Objective To observe the clinical features of congenital hypertrophy of retinal pigment epithelium （CHRPE）. Methods The clinical data of 13 CHRPE patients including visual acuity, slit-lamp microscope examination, indirect ophthalmoscope examination and fundus fluorescein angiography (FFA) were retrospectively analyzed. The patients, 9 males and 4 females, with the mean age of 27.8 years. Results All patients were unilateral, without systemic diseases and no subjective symptoms in majority. Only 30.77% of initial diagnosis was correct, other diagnosis include choroidal nevi, old chorioretinopathy or no diagnosis. The round or oval black lesion was found in ocular fundus of all patients, 7.69% was located on the optic disk, 46.15% was located on the inferior temporal retina, 30.77% was located on the superior temporal retina, 15.39％ was located on the inferior nasal retina. 92.31％ was pigmented CHRPE and 7.69％ was non-pigmented CHRPE. FFA showed blocked fluorescence and transmitted fluorescence in the lesion, few eyes were found dilated capillary vessel and fluorescent leakage on the late stage of FFA, most eyes had normal retinal vessels. Conclusion The isolated CHRPE is round or oval black lesion in ocular fundus which lack of subjective symptoms, mostly located on the peripheral retina; the FFA characteristics showed blocked fluorescence and transmitted fluorescence, and CHRPE often misdiagnosed as other disease, it should be combine the ocular fundus manifestation with the FFA to diagnose properly.
Open-globe injuries (OGI) result in complicated and diverse conditions with different mechanisms and anatomical locations, which lead to completely different outcomes based on when to perform pars plana vitrectomy (PPV) after trauma. The PPV operation time points are generally divided into early (0 - 3 days), delayed (4 - 14 days), and late (> 2 weeks). There are still some controversies about the PPV time points after OGI. Injuries with intraocular foreign bodies or high risk of infection usually need early surgery to reduce the occurrence of endophthalmitis. However corneal edema and vitreous hemorrhage can increase the difficulties for early diagnosis and surgery. If there is choroidal hemorrhage or severe trauma in the back part of the eye, delayed intervention can allow the blood clots to be liquefied and removed easily. But there is higher incidence of postoperative complications. Late surgery can reduce the difficulty of PPV, but the increased incidence of proliferative vitreoretinopathy may lead to severe retinal traction, tears and postoperative scar formation.
Objective To evaluate the effects of surgical treatment for severe ocular rupture with blood staining of cornea and non-light perception , and analyze the relative factors. Methods Seven severely rup tured eyes of 7 patients with blood staining of cornea and non-light perception underwent second-stage penetrating keratoplasty combined with vitrectomy using temporary keratoprosthesis. All injured eyes had blood staining of cornea, hemorrhage in anterior chamber and vitreous, and choroidal and retinal detachment before the second-stage surgery. The average interval of the two surgical stages was 18 days (12-21 days). The preoperative visual acuity was non-light percept ion in all injured eyes with the mean intraocular pressure of 3 mm Hg (1 mm Hg =0.133 kPa) (2-5 mm Hg).The mean follow-up period was 12 months (6-30 months). Results The postoperative visual acuity was better than light perception in 5 eyes with the best corrected visual acuity of light perception to 0.06. The retina was attached in 5 eyes (5/7). The mean postoperative intraocular pressure was 12 mm Hg(5-15 mm Hg)which was significantly higher than the preoperative one (Plt;0.05). Postoperative complications mainly included temporary intraocular hypertension (1 eye), corneal neovasculariza tion (4 eyes), cornea rejection (4 eyes), and ocular atrophy (2 eyes). Conclusion Penetrating keratoplasty combined with vitrectomy using temporary keratoprosthesis is a safe and effective method in treating severe ocular rupture with blood staining of cornea and non-light perception.

Retinoblastoma (RB) is the most serious eye disease that causes blindness, disability and death in infant. Loss of tumor suppressor gene RB1 leads to tumorigenesis of RB. With continuous innovation and development of new methods, the management of retinoblastoma has experienced a dramatic change from enucleation, external radiotherapy, intravenous chemotherapy, to intra-arterial chemotherapy combined with local treatment, enabling a more favorable outcome for survival, salvage and vision. However, the pathogenesis of RB is unclear in many aspects, the rate of eyeball removal in children with advanced RB remains high, and the innovation of new treatment are needed to be further promoted. Therefore, the key to improve the overall treatment level of RB is to pay attention to the study on pathogenesis, early diagnosis and treatment, as well as strengthen multi-center clinical trials and translational medicine research.
Eighteen cases of loss or obliteration of eye sockets from trauma or tumour were repaired with various methods: skin graft, postauricle flap with tempopostauricular blood vessel, forehead flap with temporal blood vessel and temporal flap with subcutaneous pedicle. Following 1 to 5 years follwup, the results were good and the improvement on outlooking was remarkable. The skin grafting was a simple and applicable method but it needed a longer time of blepharorrhaphy. The flap transfer was more complicated but suitable for the obliteration of the eye socket accompanied with depression deformity, but it usually would result in a secondary cicatricical malformation at the region around the eye. Thus, it was important to select a best operative method according to the specific condition.
OCT angiography (OCTA) is a fast, noninvasive and quantifiable new technique, which is especially suitable for long-term follow-up in patients with hereditary retinochoroidal degeneration, such as retinitis pigmentosa, Best vitelliform macular dystrophy, adult onset foveomacular vitelliform dystrophy, doyne honeycomb retinal dystrophy, choroideremia and Stargardt disease. During the follow-up, clinicians can find the subtle signs that explain disease development from the blood flow imaging, quantitatively describe the vascular density, timely detect and treat choroidal neovascularization. It is significant to explore the etiology and monitor the course of these diseases. With the development of more treatments for these diseases, OCTA parameters can also be used as indicators to evaluate and compare different therapeutic effects. In the future, more quantitative indicators of OCTA will be applied to evaluate the course of hereditary retinochoroidal degeneration, and provide valuable basis for early diagnosis and treatment.
Objective To study prospectively the morphological relations among hemorrhage of optic disc, defect of retinal nerve fiber layer, and peripapillary atrophy in normal-tension glaucoma (NTG). Methods Qualitative and quantitative methods were applied to evaluate the relations among hemorrhage of optic disc, defect of retinal nerve fiber layer, and peripapillary atrophy by using stereo ocular fundus photography and computer analyzer systems. Results In 37 patients (42 eyes) in NTG hemorrhage group, 50 hemorrhagic spots at optic disc was found, including coloboma of retinal nerve fiber layer in 35 eyes (83.3%)(35/42). In 35 patients (40 eyes) in non-hemorrahge group, partial coloboma of retinal nerve fiber layer was found in 21 eyes (52.5%)(21/40). The difference of incidence of coloboma of retinal nerve fiber layer between the two groups was not significant (chi;2=1.403, P=0.236). The incidence of atrophic arc in hemorrhage group differed much from which in non-hemorrhage group (chi;2=7.008, P=0.008). The area of atrophic arc at beta;section in hemorrhage group ［(2.05plusmn;0.88)mm2］ was significantly different from which in non-hemorrhage group［(1.42plusmn;0.53)mm2］(t=-2.618, P=0.012). In the follow-up period, the difference of incidence of disc-rim loss between hemorrhage and non-hemorrhage group was significant, (chi;2=5.802, P=0.016); while the difference of the incidence of visual field defect between the two groups was not. Conclusion In eyes with NTG, hemorrhage of optic disc, coloboma of retinal nerve fiber layer and atrophic arc are closely related. More disc-rim loss and changes of atrophic-arc area in hemorrhage group in the follow-up period suggests that hemorrhage of optic disc is the risk factor of development of NTG.

In recent years，there are more and more cases of retinal infectious diseases in China，however，the diagnosis and management of those patients are still big challenges for our ophthalmic clinicians. It is our top priority to improve their capacity of early diagnosis for those diseases. We need to know the relationship between retinal infectious diseases and systemic infections, their predisposing factors. We also need to be familiar with the typical as well as atypical clinical features of those diseases. Vitreoretinal surgery already becomes a powerful tool to make diagnosis of retinal infectious diseases now；we need to make full use of this tool combined with modern technologies of microbiology, cytology, immunology and molecular biology to provide objective scientific evidences for the early diagnosis of retinal infectious diseases.
Objective To evaluate the efficacy of transpupillary thermotherapy（TTT）on three kinds of intraocular benign tumors. Methods Seventeen patients with 3 kinds of intraocular tumors，3 eyes of 3 patients with papillary hemangioma，9 eyes of 9 patients with choroidal hemangioma and 8 eyes of 5 patients with choroidal osteoma were treated with transpupillary thermotherapy.All patients underwent pretreatment ocular examination，including visual acuity，biomicroscopy for anterior segment and fundus examination，fundus fluorescein and indocyanine green angiography，optic coherence tomography，perimetry test，ultrasonography，and CT.TTT was conducted with infrared diode laser at810nm.with power of 360-1200 mW;beam diameter of 3 mm or combined 2-5 spots according to the tumor size;the exposure time was 60-80 seconds.The treatment was completed in one session，and another treatment was given 1-3 month later if active leakage demonstrated.The follow-up period was 6-36 months（mean 14.5 month）. Results The best corrected visual acuity with Snellen chart on average for papillary hemangioma was 0.17 before TTT and 0.27 after;for choroidal hemangioma was 0.39 before TTT and 0.46 after;for choroidal osteoma was 0.20 before TTT and 0.31 after.Three eyes with papillary hemangioma had operation to release subretinal fluid and intraocular laser coagulation;the tumor remained reddish color with dilated vessels and patches of hemorrhages on the surface.After TTT the color appeared pale yellowish，hemorrhages absorbed，subretinal fluid subsided，and choroidal retinal atrophy disclosed along the lower border of the tumor.In 9 eyes with choroidal hemangioma, the red-light area disappeared, subretinal fluid subsided, and the pigment proliferation in the treatment area was found.Eight eyes with choroidal osteoma had choroidal neovessels and macular hemorrhages;after TTT blood disappeared，subretinal fluid absorbed，and the color of tumor showed pale yellow with dark pigment and thin scar tissue.There was no significant complication associated with TTT. Conclusions Transpupillary thermotherapy is effective on papillary hemangioma，circumscribed choroidal hemangioma and choroidal osteoma either as preliminary or supplementary treatment.
