Purpose: To report on a case of Crohn's disease and unilateral retinal vasculitis, branch retinal artery occlusion and subsequent retinal neovascularization., Methods: We examined a 38-year-old woman with severe left visual loss and biopsy-proven Crohn's disease diagnosed four years prior to the ocular involvement. A Heidelberg scanning laser ophthalmoscope was used for fundus fluorescein angiography and indocyanine green angiography. Retinal neovascularization was detected during the follow-up., Results: Successful regression of retinal neovascularization was achieved after argon green laser panretinal photocoagulation in addition to oral steroid and salazopyrine., Conclusion: Retinal vascular involvement is a rare ocular feature of Crohn's disease and may result in retinal neovascularization that may necessitate prompt laser photocoagulation.

Purpose: To evaluate pseudoexfoliation (PE) and pre-existent glaucoma in eyes with branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO)., Methods: Consecutive eyes with a diagnosis of BRVO (73 eyes of 70 patients) and CRVO (53 eyes of 49 patients) examined between July and December 1998 comprised the study eyes. Age-matched control group consisted of 384 eyes of 192 outpatients. The prevalence of PE and glaucoma were determined and appropriate statistical tests were performed., Results: PE was present in six of 73 eyes with BRVO (8.2%), 11 of 53 eyes with CRVO (20.8%) and 20 of 384 control eyes (5.2%). Two of 73 eyes with BRVO (2.7%) and 10 of 53 eyes with CRVO (18.9%) had glaucoma. Compared with the control eyes, PE was significantly more common in eyes with CRVO and coexistent glaucoma was significantly more common both in eyes with CRVO and in eyes with BRVO., Conclusion: While glaucoma seems to be a risk factor both for BRVO and CRVO, PE is a likely risk factor for CRVO.

We report a case with progressive visual loss whose ophthalmic examination revealed bilateral optic atrophy and choroidal folds in the left eye. Neuroimaging demonstrated a sellar mass compressing the optic chiasm and the left optic nerve was to be stretched. We assume the traction created on the optic nerve by the mass stretched the optic nerve and caused the choroidal folds.
