Sudden mono-ocular blindness with recurrent transient diplopia and ptosis in a middle-aged woman.

Sudden painless loss of vision is an ophthalmologic and a medical emergency resulting from various causes such as occlusion of retinal artery or vein, macular or vitreous haemorrhages, retinal detachment, and anterior and posterior ischaemic optic neuropathy. We report a 48-year-old woman presenting with right monocular blindness due to branch retinal artery occlusion whose vision recovered due to timely paracentesis coupled with treatment with adequate antiplatelet agents and anticoagulants. The patient had transient diplopia and ptosis despite adequate antiplatelet agents and anticoagulants.
