ObjectiveTo observe the multimodal imaging characteristics of combined hamatoma of the retina and retinal pigment epithelium (CHRRPE).MethodsA retrospective case study. From January 2013 to December 2017, 6 CHRRPE patients (6 eyes) diagnosed in Department of Ophthalmology, Sun Yat-sen Memorial Hospital were included in the study. There were 4 males and 2 females, with the mean age of 12.0±8.10 years. There were 5 eyes with BCVA ≤0.1, 1 eye with BCVA＞1.0. Corneal fluoroscopy showed 1 eye with an external oblique 15°, and the remaining eye had no abnormalities in the anterior segment. All eyes underwent fundus color photography, FAF, FFA, ICGA, OCT and color Doppler flow imaging (CDFI). The multimodal imaging characteristics were observed.ResultsAll the affected eyes CHRRPE were located in the posterior pole and showed mild elevation. Most of the retinal neuroepithelial layers had different degrees of hyperplasia, vascular tortuosity and retinal folds. Of the 6 eyes, 4 eyes (66.7%) involving the macula and optic disc, only 2 eyes (33.3%) involving the macula. OCT showed that the structure of the neuroepithelial layer was unclear and the signal intensity was uneven; it involved 2 eyes of the whole retina (33.3%) and only 4 eyes of the neuroepithelial layer (66.7%). FFA and ICGA showed that the choroidal background fluorescence of the early lesions was weakened, and the lesions showed slightly weak fluorescence; the late telangiectasia fluorescein was obviously leaked, and the lesions were stained with fluorescence. FAF mainly appears as weak autofluorescence with a small amount of strong autofluorescence. CDFI has no characteristic performance.ConclusionsCHRRPE is mainly a membrane-like hyperplasia without angiogenesis, involving the retinal neuroepithelial layer, and may also involve the entire retina. OCT is dominated by strong reflection; AF, FFA and ICGA are mainly weak fluorescence.
Objective To observe the multimodal image features of inflammatory lesions and choroidal neovascularization (CNV) in multifocal choroiditis (MFC). MethodsA retrospective clinical analysis. A total of 90 eyes of 46 patients with MFC diagnosed in the Department of Ophthalmology of Yunnan University Affiliated Hospital from May 2017 to April 2021 were included in the study. Among them, there were 21 males and 25 females; the average age was 38.30±8.97 years old. Twenty-nine cases of MFC were diagnosed in the past, and they visited the doctor again due to new symptoms; 17 cases without a clear past medical history were the first visits. All eyes underwent color fundus photography, fluorescein fundus angiography (FFA), optical coherence tomography (OCT), and OCT angiography (OCTA). With reference to the literature and the results of multimodal fundus imaging examinations, MFC lesions were divided into active CNV lesions, inactive CNV lesions, active inflammatory lesions, and inactive inflammatory lesions, with 31 (34.4%, 31/90), 12 (13.3%, 12/90), 26 (28.9%, 26/90), 90 (100.0%, 90/90) eyes. Nineteen eyes were treated with anti-vascular endothelial growth factor drugs. To summarize and analyze the manifestations of inflammatory lesions and CNV lesions in different imaging examinations. The Wilcoxon rank test was used to compare the detection rate of CNV lesions between FFA and OCTA. ResultsIn eyes with active inflammatory lesions and active CNV lesions, yellow-white lesions, retinal hemorrhage and exudation were seen on fundus color photography; FFA examination showed fluorescein leakage in the lesions; OCT examination showed retinal pigment epithelium (RPE) layer in the lesions was uplifted, the boundary was unclear, combined with subretinal and intraretinal fluid; OCTA examination showed that there was no blood flow signal in each layer of vascular tissue in active inflammatory lesions, and blood flow signals were seen in active CNV lesions. In the eyes of inactive inflammatory lesions and inactive CNV lesions, the fundus color photography showed that the lesions had clear boundaries without bleeding or exudation; FFA examination, the lesions were fluorescently stained, and there was no fluorescein leakage; OCT examination, inactive CNV lesions manifested as raised lesions with clear boundaries, and inactive inflammation manifested as scars formed by mild RPE hyperplasia or depressions in outer structures formed by atrophy; OCTA examination, inactive inflammatory lesions showed patchy loss of blood flow signal or penetrating blood flow signal below, blood flow signal can be seen in inactive CNV lesions. ConclusionMFC active inflammatory lesions and active CNV lesions are often accompanied by retinal hemorrhage and exudation; FFA shows fluorescein leakage; OCT shows that the boundary of raised lesions is unclear; OCTA can identify the nature of CNV or inflammatory lesions.
Objective To observe the clinical and multimodel image features in patients of acute macular neuroretinopathy (AMN) associated with COVID-19. MethodsClinical data and multimodal imaging results in 12 patients (24 eyes) of AMN associated with COVID-19 which were diagnosed in our Department of Ophthalmology, The Second Hospital of The Army Medical University ranging from December 2022 to January 2023 were included. All patients were examined by best-corrected visual acuity (BCVA), color fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA), visual field tests, high-resolution computed tomography of the lungs and inflammation-related laboratory tests. After diagnosis, patients were reveived methylcobalamin and Ginaton therapy, 6 patients receiced intravenous dripping of dexamethasone. The follow-up time of this study was 4 weeks. ResultsThere were 1 male (2 eyes) and 11 females (22 eyes), with the mean age of (29.00±5.17) years. For all cases, decreased vision presented 1 to 2 days after patients being suffered from several flu-like symptoms of COVID-19. Ten eyes in 5 patients were at the acute phrase of AMN, which the vision decrease occurred 1-5 days after they were diagnosed with COVID-19; 14 eyes in 7 patients were at the progressive stage of AMN, which they were diagnosed with COVID-19 for more than 5 days. The BCVA of patients were 0.02-0.9, in company with one or more central/pericentral scotoma. Fundus ophthalmoscopy revealed reddish-brown lesion around macula, IR imaging demonstrated localized areas of hypo-shape lesions in the macula. For 16 eyes, their OCTA revealed a decreased density of blood flow in the deep layer of retinal capillary plexus, and OCT revealed that high reflex bands existed in the outer nuclear layer (ONL) and outer plexiform layer of the retina at the acute phrase of AMN, in accompany with hypo-reflection in ellipsoid zone (EZ) and interdigitation zone (IZ); for retina at the progressive stage of AMN, ONL became thinner in some cases and the continuation interruption occurred in EZ and IZ. For en-face OCT, high reflex bands with clear edges existed in the ONL and EZ layer of the retina at the acute phrase of AMN, but no high reflex bands existed in the ONL and EZ layers of the retina at the progressive stage of AMN. Instead, hypo-reflection with similar shape occurred in the EZ and IZ layers at the progressive stage of AMN. During treatment, 5 patients at the acute phrase reported a shrinking central scotomas and raised BCVA, otherwise the BCVA of 7 patients at the progressive stage changed slightly. For 10 eyes at the acute phrase of AMN, OCT revealed that the high reflex bands of ONL and OPL missed within 1 week. En-face OCT revealed the hyper-reflection in the ONL and EZ layers of retina in the acute phrase of AMN receded within 1 week, but hypo-reflection of ONL and EZ still presented. ConclusionsFor AMN associated with COVID-19, IR imaging demonstrated localized areas of hypo-shape lesions in the macula. OCT revealed high reflex bands in ONL and OPL of the retina at the acute phrase of AMN, but hypo-reflection of ONL and EZ still presented. The continuation interruption occurred in EZ and IZ at the progressive phrase. En-face OCT revealed hyper-reflection in ONL and EZ of the retina at the acute phrase which receded within 1 week, and hypo-reflection in EZ and IZ of the retina presented at all phrases during AMN progression.
ObjectiveTo observe the multimodal imaging features of acute macular neuroretinopathy (AMN) associated with COVID-19. MethodsA retrospective case study. A total of 52 eyes of 26 patients of AMN associated with COVID-19 diagnosed in Handan Eye Hospital from December 8 to 20, 2022 were included in the study. There were 8 males and 18 females, with the mean age of (33.8±8.1) years. All the patients were bilateral. The time from diagnosis of COVID-19 to the onset of vision loss was 3 to 6 days. All patients underwent the examinations of best corrected visual acuity (BCVA), fundus color photography, infrared fundus photography (IR), fundus autofluorescence (AF), and optical coherence tomography (OCT). Fluorescein fundus angiography (FFA) combined with indoxine green angiography (ICGA) were performed in 12 eyes, and visual field were performed in 18 eyes. Multimodal image features of the affected eye were retrospectively analyzed. ResultsThe BCVA of the affected eye was 0.25 to 1.0. Round or mottled grayish-white lesions in the macular area were seen in all affected eyes. IR examination showed irregular map-like weak reflex in macular region. AF examination showed speckled fluorescence enhancement in lesion related areas in 3 eyes. FFA combined with ICGA showed weak fluorescence in the macular region in 8 eyes. OCT examination showed patchy strong reflection in the outer plexus layer (OPL) and outer nuclear layer (ONL) of macular area in all affected eyes, and partial absence of outer membrane and ellipsoid band. The en-face OCT showed petal-like intense refleciton between OPL and ONL. Eighteen eyes underwent visual field, and 15 eyes had central dark spots. ConclusionThe characteristic manifestations of AMN associated with COVID-19 are speckled or round-like grayish-white lesions in the macular area, weak reflexes in IR, enhanced OPL and ONL reflexes in OCT, and petal-like intense refleciton changes between OPL and ONL can be seen in en-face OCT.
ObjectiveTo observe the multimodal imaging characteristics of multiple evanescent white dot syndrom (MEWDS).MethodsThis was a retrospective series case study. Eighteen patients (18 eyes) diagnosed with MEWDS in Eye Center of The Second People’s Hospital of Foshan from September 2015 to April 2017 were enrolled in this study. There were 12 females and 6 males, with the mean age of 35.9 years. The disease course ranged from 3 to 90 days, with the mean of 14 days. All the patients underwent BCVA, slit-lamp microscope with +90D preset lens, fundus photography, spectral domain OCT (SD-OCT) and FAF examinations. FFA was simultaneously performed in 6 eyes, FFA and ICGA were simultaneously performed in 12 eyes. Ten patients received the treatment of glucocorticoids and vasodilator substance, and other 8 patients without any treatment. The follow-up duration was 4.5 months. The multimodal imaging characteristics were reviewed and analyzed.ResultsFundus color photography showed a variable number of small dots and large spots lesions (14 eyes), and/or fovea granularity (7 eyes) and disk swelling (5 eyes). A variable number of little dots and larger spots lesions showed respectively in FFA, FAF and ICGA were needle-like dots distributed in a wreathlike pattern and a large plaque occasionally confluent of early highly fluorescent, highly autofluorescence and hypofluoresence. Combined hypofluorescent spots with overlying dots were observed in 10 eyes of the late stages of the ICGA. Black lesions in the gray background show in ICGA were the most obvious and the most extensive, gray-white lesions in the gray-black show in FAF were the second, light gray-black lesions in the gray show in FFA were the least. Gray-white lesions in an orange background show in fundus photography were not obvious and transient. SD-OCT showed disruption of the ellipsoid zone and/or accumulations of hyperreflective material from the ellipsoid layer toward the outer plexiform layer and vitreous cells. During the period of following-up, some patients were prescribed low-dose glucocorticoid and some not, almost all the patients except one patient experienced recovery in BCVA and the lesions in fundus imaging.ConclusionsThe lesions in MEWDS eyes in modern multimodal imaging modalities among fundus photography (fovea granularity), FFA (needle-like dots distributed in a wreathlike pattern and a large plaque occasionally confluent of early highly fluorescent), ICGA (flake hypofluorescent) and SD-OCT (disruption of the ellipsoid zone) showed good consistency. Almost eyes were recovery.
ObjectiveTo observe the multimodal imaging characteristics of tamoxifen retinopathy. MethodsA retrospective case study. From January 2019 to December 2021, 4 patients (8 eyes) with tamoxifen retinopathy diagnosed in Tangshan Eye Hospital were included in the study. All patients were female, with sick binoculus. The age was 59.5±4.6 years. After breast cancer resection, tamoxifen 20 mg/d was taken orally consecutively, including 1, 1, and 2 cases who took tamoxifen orally for 5, 7, and ≥10 years. All eyes were examined by fundus color photography, optical coherence tomography (OCT), OCT angiography (OCTA), fundus fluorescein angiography (FFA), and fundus autofluorescence (AF). The multi-mode image features of the fundus of the affected eyes were observed. ResultsThe yellow white dot crystal like material deposition in the macular area was observed in all eyes. In fundus AF examination, macular area showed patchy strong AF. FFA examination showed telangiectasia and fluorescein leakage in macular area at late stage. OCT showed that punctate strong reflexes could be seen between the neuroepithelial layers in the macular region with the formation of a space between the neuroepithelial layers, the interruption of the elliptical zone (EZ), and the formation of a hole in the outer lamella including 4, 5 and 3 eyes; The thickness of ganglion cells in macular region decreased in 7 eyes. OCTA showed that the blood flow density of the superficial retinal capillary plexus around the arch ring was decreased, and the retinal venules were dilated in 2 eyes; Deep capillary plexus (DCP) showed telangiectasia. ConclusionDeposition of yellowish white dot like crystals can be seen in the macular region of tamoxifen retinopathy; dotted strong reflex between neuroepithelial layers, cavity formation, thinning of ganglion cell layer, EZ middle fissure and outer lamellar fissure; DCP capillaries and venules around the arch were dilated; telangiectasia in macular region; flaky strong AF in macular region.
ObjectiveTo observe and analyze the multimodal imaging characteristics of fundus in patients with sympathetic ophthalmia (SO). Methods A retrospective study. From October 2012 to December 2021, 28 patients (36 eyes) diagnosed SO in the Department of Ophthalmology, Beijing Tongren Hospital were inclued in the study. There were 19 males (25 eyes) and 9 females (11 eyes), with the mean age of 51.61±12.02 years. There were 8 exciting eyes and 28 sympathizing eyes. The time to onset after trauma or surgery was 46.10±107.98 months. All patients underwent examinations including vision test, color fundus photograph, optical coherence tomography (OCT), fundus fluorescence angiography (FFA), indocyanine green angiography (ICGA). Angio-OCT (OCTA) was performed on 3 eyes and fundus autofluorescence (AF) was performed on 8 eyes. The early and late phase were defined respectively as ≤2 months and ＞2 months. Their multimodal imaging characteristics were summarized. ResultsIn 8 exciting eyes, subretinal fibrosis with mutifocal retinal atrophy and pigmentation was noted in 5 eyes (62.50%, 5/8), the other 3 eyes showed sunset glow fundus (37.50%, 3/8). In 28 sympathizing eyes, in the early phase, the fundus photograph showed shallow retinal detachment with optic disc edema in 9 eyes (32.14%, 9/28); in the late phase, peripapillary yellowish-white subretinal lesions in 11 eyes (39.29%, 11/28). In the late course of the disease, there were yellow-white lesions around the optic disc (peridisc) and peripheral subretinal area in 11 eyes (39.29%, 11/28). Dalen-Fuchs nodules were found in 10 eyes (35.71%, 10/28). On OCT, multiple serous retinal detachment and irregular choroidal folds were noted in the early phase; hill-like subretinal hyperreflective elevation was noted in peripapillary area and subfovea with presence of cystic spaces in the intraretina in the late phase. FFA examination showed "pinpoint-like" strong fluorescence in the early stage, and "multi-lake-like" fluorescein accumulation and leakage in the late stage; "map-like" weak fluorescence around the disc in the early stage of the disease, dot-like strong fluorescence lesions in each quadrant of the peripheral retina, and fluorescence in the late stage of the disease course. enhanced. ICGA examination showed that the FFA strong fluorescence lesions in the middle and late stages were weak fluorescence. FAF examination, point-like strong and weak autofluorescence lesions with unclear boundaries. Nine sympathizing eyes with subretinal yellow-white lesions has vision without light-0.1 (significantly decreased vison), while 8 eyes with sunset glow fundus was 0.5-1.0 (mildly decreased vison). ConclusionsSO could not only show the semblable features of acute phases of Vogt-Koyanagi-Harada syndrome, but also the yellowish-white lesions in the peripapillary area, macula and periphery. Most of the eyes with peripapillary lesions has a significantly decreased vison, while the eyes with sunset glow fundus has a mildly decreased vison.
Objective To evaluate the clinical features of acute macular neuroretinopathy (AMN) associated with COVID-19. MethodsA retrospective case series studies. A total of 12 eyes of 8 patients diagnosed of AMN associated with COVID-19 at Peking University People’s Hospital from December 5, 2022 to January 5, 2023 were included. Of the 8 patients, 2 were male (4 eyes) and 6 were female (8 eyes), with an average age of (29.38±8.60) years. All patients underwent best-corrected visual acuity (BCVA), spectral-domain optical coherence tomography (OCT), and infra-red fundus photography (IR). After definite diagnosis, the patients were given symptomatic treatment such as local vasodilation, anti-inflammatory and systemic circulation improvement and nutritional nerve. Follow-up time was 21-30 days weeks. Clinical manifestations, OCT and IR image characteristics, and treatment outcomes were retrospectively analyzed. ResultsThe time from diagnosis of COVID-19 to the onset of ocular symptoms was (3.00±0.93) days. Among 12 eyes, 6 had complaints of paracentral scotoma, with 2 of them accompanied by visual acuity loss; and 6 had complaints of dark shadows in the vision, with 2 of them accompanied by visual acuity loss. At the initial examination, 2 eyes had a BCVA of less than 0.05, 2 eyes had a BCVA between 0.4 and 0.6, and 8 eyes had a BCVA between 0.8 and 1.0. At the last follow-up, visual symptoms improved in 7 eyes and remained unchanged in 5 eyes. Fundus color photography showed reddish-brown lesions in the macular area. Spectral-domain OCT revealed localized thickening and strong reflection of the outer plexiform layer (OPL) in the macular area, patchy strong reflections in the outer nuclear layer (ONL), and varying degrees of local discontinuity in the adjacent external limiting membrane, ellipsoid zone/interdigitation zone (EZ/IZ), with reduced local reflection in the adjacent retinal pigment epithelium layer in 2 eyes. The strong reflection area of the ONL on corresponding structural OCT was observed more clearly as a lesion range with strong reflection on en-face OCT. The incomplete structure of the EZ/IZ band was observed more clearly as a lesion range with weak reflection on en-face OCT. IR showed several clear-bordered and weakly reflecting lesions at the center of the macula, with the tip pointing to the fovea. ConclusionsAMN associated with COVID-19 tends to occur in young females. The OCT findings of AMN are characterized by strong reflections in the OPL and ONL, and lesion ranges can be observed more clearly at different levels using en-face OCT. The lesions on IR appear as weak reflections.
ObjectiveTo observe and analyze the clinical and imaging features of eyes with cystoid macular degeneration (CMD) secondary to chronic central serous chorioretinopathy (cCSC). MethodsA retrospective clinical study. From February 2018 to June 2023, 9 patients of 15 eyes with cCSC secondary CMD diagnosed by ophthalmology examination in Yunnan University Affiliated Hospital were included in the study. All patients were male. The age was (53.67±3.83) years. The cases of binocular and monocular were 6 and 3 respectively. The visual acuity of the affected eye ranges from 0.02 to 0.1, which cannot be corrected. Visual acuity decreased and the duration of shadow occlusion was ＞1 year. Half dose photodynamic therapy (PDT) was performed on 8 eyes. All the patients underwent the best corrected visual acuity, posterior mydriatic fundus color photography, infrared fundus photography (IR), fundus autofluorescence (AF), fluorescein fundus angiography (FFA), optical coherence tomography (OCT), and multi-wavelength dazzling imaging (MC). The patients who received half dose PDT were followed up until 3 months after treatment. Patients who did not receive treatment were followed up to 2 years after the first diagnosis. ResultsThe light reflection in macular area decreased or disappeared in all eyes, and abnormal macular pigmentation was observed in 12 eyes. IR examination showed diffuse patchy weak fluorescence in the macular area in all affected eyes, and dotted strong fluorescence in the periphery. Fundus AF examination showed disc-like weak AF in the macular area, and scattered small amounts of strong AF in the middle and margins, among which the retinal pigment epithelium (RPE) atrophy trace in the macular area was observed in 7 eyes. By MC examination, the green signal in the macular area of the posterior pole of all affected eyes was uneven and mottled. FFA examination showed that no abnormal fluorescein leakage was observed in 15 eyes and 8 eyes showed strong fluorescence caused by diffuse permeation fluorescence. A small amount of active fluorescein was found in 7 eyes. OCT examination showed that there were several cystic cavities of different sizes in all the affected eyes, RPE atrophied to different degrees, and RPE cell compensatory ridges and tubular structures in the outer retina were seen in 6 eyes; 7 eyes with CMD and active leakage showed signs of subcortical fluid accumulation. Choroidal hypertrophy was seen in all affected eyes, with significant expansion of the great vascular layer and compression of the middle vascular layer and capillary layer. In 8 eyes treated with half-dose PDT, 6 eyes were ineffective at 3 months after treatment. The treatment was effective in 2 eyes. In 7 eyes that did not receive half-dose PDT, CMD structure did not improve significantly after 2 years of follow-up. The visual acuity decreased with the prolongation of the disease. ConclusionsCMD is more common in cCSC with a long course of disease, which has significant effects on vision and poor prognosis. Fundus color photography shows that the reflection in the macular area of the pole is weakened or disappeared, which may be combined with macular abnormal pigmentation. IR and AF examination show uneven fluorescence in macular area. The green signal in macular area is not uniform according to MC inspection. FFA shows strong fluorescence caused by diffuse permeable fluorescence and fluorescein leakage in active lesions. OCT examination shows that multiple small sacs or connections between sacs were broken and fused, and RPE atrophied to varying degrees.
Objective To observe the multimodal imaging features of retinal diseases associated with COVID-19. MethodsA retrospective case study. Sixteen patients (30 eyes) of retinal diseases associated with COVID-19 admitted to the Ophthalmology Department of the Second People's Hospital of Zhengzhou in December 2022 were included in the study. There were 5 males and 11 females, with the mean age of (26.69±9.88) years; 14 patients were bilateral and 2 patients were unilateral. The time of ocular symptoms after the diagnosis of COVID-19 was (2.63±0.89) days. All patients underwent the examinations of best corrtected visual acuity (BCVA), fundus color photography (FP), infrared fundus photography (IR), optical coherence tomography (OCT). Fluorescein fundus angiography (FFA) was performed in 2 patients (4 eyes). There were 20 eyes with acute macular neuroretinopathy (AMN), including 6 eyes with cotton wool spots; 10 eyes with Purtscher-like retinopathy (PLR). The BCVA of the patients was 0.1-1.0. No obvious abnormality was found in anterior segment examination. The features of FP, IR and OCT were analyzed retrospectively. ResultsIn 20 eyes of AMN, irregular reddish brown lesions in the central or paracentral area of the macula in 14 eyes; FP showed no obvious abnormality in 6 eyes; IR showed irregular map like low reflection in the central or paracentral area of macular in all eyes; OCT showed hyperreflectivity in outer plexiform layer and outer nuclear layer, hyporeflectivity in the ellipsoid zone and photoreceptor layers in all eyes; no abnormal fluorecence was observed in 2 eyes examined by FFA. In 10 eyes with PLR, cotton wool spots and retinal hemorrhage were observed in the posterior pole and/or peripapillary area, and the peripheral retina was generally normal, Purtscher spot was found in 5 eyes and macular edema in 4 eyes; OCT showed strong reflex signal in neuroepithelial layers, edema in neuroepithelial layers in 6 eyes; in the 2 eyes examined by FFA, fluorescein leakage from the retinal vein wall was observed, the posterior pole and peripapillary area retinal arteriole occlusions showed patchy hypofluorescence, the fluorescence was obscured by retinal hemorrhage below at inferior retina. ConclusionsFor AMN associated with COVID-19, IR can show the lesion contour , OCT shows lesions in the outer retina. PLR associated with COVID-19 are usually at the posterior pole and/or peripapillary area in FP, OCT shows neurocortical edema.
