Retino-choroidal ischemia in central retinal vein occlusion

A 41-year-old gentleman with insulin dependent diabetes had decreased vision in the right eye due to non-ischemic central retinal vein occlusion with macular edema. One month following intravitreal ranibizumab, he developed retinochoroidal ischemia with further loss of vision. Authors show the fluorescein angiographic transition from non-ischemic central retinal vein occlusion to retino-choroidal ischemia

Volcano like pattern in optical coherence tomography in chronic diabetic macular edema

In this article we herein report an interesting vitreo-macular interface abnormality associated with chronic diabetic cystoid macular edema. It is an observational case study of three diabetic patients examined in the diabetic clinic. All the patients had proliferative diabetic retinopathy with chronic macular edema. A serial cross sectional OCT examination and tracking of both the longitudinal progression of macular thickening and vitreo-macular interface revealed cystoid macular edema with a characteristic hyperreflective vitreous shadow emerging from the vitreofoveal interface. All the patients had dehiscence of inner retinal layers. This particular morphological feature at the vitreo-foveolar interface, which we name as "volcano sign", has not been described earlier. The probable mechanism of such a finding probably could be due to slow progressive leakage of chronic cytoid fluid into the vitreous with condensation of the overlying vitreous. Vitreo-macular traction followed by posterior vitreous detachment probably would have contributed to such a morphological event

Verteporfin therapy for subfoveal choroidal neovascularisation associated with choroidal osteoma / 国际眼科杂志(Guoji Yanke Zazhi)

· AIM: To report a case of verteporfin therapy for subfoveal choroidal neovascularisation associated with choroidal osteoma.· METHODS: A 32-year-old patient was diagnosed as subfoveal choroidal neovascularisation (CNV) associated with choroidal osteoma in the right eye, with present visual acuity (VA) of 20/80; N24. He underwent 2 sessions of photodynamic therapy (PDT) in the right eye for 12mo.· RESULTS: At the end of 12mo, the patient's VA was 20/200 with complete regression of the CNV.· CONCLUSION: PDT could be a treatment option in subfoveal CNV associated with choroidal osteoma.
