VASCULITIS OF RETINA

Purpose The purpose of this study is to determine aetiologies of vascu litis of retina in Morocco. Material and methods This is a retrospecti ve study on 108 cases of vasculitis of retina admitted in the ophthalm ology department, for a 5-year period (1987-1993). Our patients had a complete ophthalmological examination:fluorescine angiography, colour vision, general examination and biological study. Results Many aetiolo gies have been found predominantly Behcet's disease. The neovasculariz ation of retina which complicates the vasculitis was detected in 30 % of our patients. A laser photocoagulation was performed on these cases , sometimes a vitrectomy was necessary when a haemorrhage of vitreous body occurred complicating the neo-vessels of retina. The therapeutics received by our patients was based on the corticotherapy. An An immun osuppression treatment was prescribed in most cases of Behcet's diseas e and in severe vasculitis. Outcome after treatment has been satisfact ory, but many patients relapse very frequently, mainly those with Behc et's disease. Conclusion Causes of vascular retinitis are variable, mo st of them are due to Behcet's disease.
