The aim of the study is to analyse the aetiology and clinical presentation of rubeosis iridis in a tertiary eye care centre.
MATERIALS AND METHODS
It was an analytical prospective study. About 50 patients were studied at our institution for six months. The aetiology and the clinical profile of the patients with rubeosis iridis was studied. Inclusion criteria was patients with comorbid conditions like diabetes and hypertension were included in this study. Patients with preexisting glaucoma either primary open angle or angle closure glaucoma and patients who had received more than three sittings of pan-retinal photocoagulation were excluded in this study. The initial presenting complaints, detailed history of the course of the disease, visual acuity, detailed slit lamp examination, intraocular pressure, detailed fundus examination and gonioscopic grading was done for all the patients.
Almost, all the cases had florid rubeosis along the pupillary border. Those extending to the angles presented with an increase in the intraocular pressure. Patients with chronic uveitis, long-standing retinal detachment and vitreous haemorrhage presented with poor vision. Male preponderance was noted in our study. About 70% presented with raised intraocular pressure. Unilateral presentation of rubeosis iridis was noted in the patients presenting with chronic uveitis and long-standing retinal detachment.
In our study, diabetes topped the aetiology of rubeosis very closely followed by central retinal vein occlusion and hypertension. It was also noted in few cases of chronic uveitis and long-standing retinal detachment. About 70% of the study population presented with neovascular glaucoma.
