A 65 year old male patient presented with pain, redness and loss of vision in right eye. Slit lamp examination revealed mid dilated, fixed pupil with rubeosisiridis. Intraocular pressure was raised in right eye. Fluroscein examination showed dye leaking in right eye anterior chamber due to iris neovascularisation. Carotid Doppler and CT carotid angiography study showed right common carotid artery atherosclerotic plaque and reduced blood flow in right central retinal artery. Proper ophthalmological evaluation of patient having carotid artery disease is essential for prevention of intractable neovascular glaucoma and permanent blindness.
