Purpose: To present an interesting case report of a healthy 34-year old female who presented to our ophthalmology clinic with unilateral non ischemic central retinal vein occlusion, two months after she was tested positive for SARS-CoV-2.

Case Presentation: We present a 34-y old female who was referred to our ophthalmology clinic with blurred vision in her right eye, without other systemic symptoms. She was diagnosed as COVID-19 two months before onset of her visual symptoms. Further investigation ruled out any medical disease or any other known etiological factor related to hypercoagulable state.

Results: During eye examination BCVA was 6/6 on both eyes. The anterior segment was without pathological changes, normal pupillary light reflex and intraocular pressure. On fundus examination, the right eye showed presence of dot-blot and flame-shaped hemorrhages in all quadrants, dilated and tortuous veins and mild swollen optic disc. Fluorescein angiography showed delay in arteriovenous transit time, perivenous fluorescein staining of dilated tortuous veins and retinal hemorrhages were masking the retinal capillary bed, confirming non ischemic central retinal vein occlusion. OCT imaging did not show macular edema and therefore the patient was only observed.

Conclusion: The hypercoagulable state induced by COVID-19 may be associated with CRVO. This may implicate awaring of COVID-19 related thromboembolic phenomena as a cause of CRVO. We hope that our case report that illustrate CRVO as a complication of COVID-19 will allow us to increase more our knowledge about various possible ocular manifestations of COVID-19 disease. Further studies and case reports should be reported to better understand the connectivity between Covid-19 and retinal vascular diseases.
