Unilateral retinal vasculitis, branch retinal artery occlusion and subsequent retinal neovascularization in Crohn's disease

摘要

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 laserpanretinal 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.
