Central Retinal Artery Occlusion with Patent Cilioretinal Ar
A 35 year old female presented with sudden painless decrease of vision in her right eye. Visual acuity in her right eye was 6/12 on distant Snellen’s acuity chart. A relative afferent pupillary defect was noted. Fundus examination in right eye showed optic disc swelling, retinal opacification and retinal edema with a perfused area of retina (Figure 1, arrowhead) at posterior pole suggestive of central retinal artery occlusion with patent cilioretinal artery. A detailed medical history revealed that she had taken a dose of depot progesterone three months back for contraception. Complete haemogram, coagulation profile and lipid profile was normal. Carotid Doppler showed presence of a thrombus in right internal carotid artery for which she is under care of cardiologist. Central retinal artery occlusion with a patent cilioretinal artery presents with constriction of visual fields but central vision is preserved.
