Background:
Cilioretinal artery occlusion rarely results in neovascular glaucoma, especially in cases of extensive cilioretinal infarction and combined retinal vascular occlusion.
Case:
A 62-year-old man with diabetes mellitus and essential hypertension showed a visual acuity of counting fingers, retinal whitening temporal to the optic disc with mild dilation and tortuosity of the retinal veins, and retinal hemorrhages in four quadrants of his right eye. Fluorescein angiography demonstrated a delayed filling of the central retinal vein and cilioretinal artery.
Observations:
Two months later, neovascular glaucoma developed and retinal ablation was performed using an argon laser. Trabeculectomy was also performed due to the intractability of the glaucoma, and central artery occlusion was found. On magnetic resonance angiography, the right distal common carotid artery was irregularly narrowed and the right ophthalmic artery was almost entirely occluded.
Conclusions:
In cases of cilioretinal artery occlusion and perfused central retinal vein occlusion with multiple risk factors, close follow-up is advised.
