Purpose: To sum up ophthalmological features of the Covid-19 and effects that its therapies may have on the ocular tissues, even after recovery. There is general uncertainty about ocular sequelae in Covid-19 patients which corresponds to our data needs and this research can help us narrow down to concrete, researchable findings. The established literature so far primarily focuses on ocular manifestations during Covid-19. Methods: Cross-sectional observation study conducted in a tertiary care, teaching hospital on all patients >18 years. Study population of 105 patients included all adult Covid-19 positive patients 10 days after symptom onset plus at least 3 additional days without symptoms and who have been discharged. Patients were followed up on day 15, day 30 and day 90 post recovery to screen for ocular sequelae such as retinal alterations and other parameters like changes in visual acuity, intraocular pressure, and ocular surface manifestations. Results: Sixty-one patients had no abnormalities on eye examination. Retinal hemorrhages were found in 4 patients (4%) and small drusens were noted in 6 cases (6%). Two cases each of Central Serous Chorioretinopathy (CSCR) in young and epiretinal membrane were noted. Single patients also presented with cilioretinal artery occlusion and central retinal vein occlusion. Orbital mucormycosis was noted in 17 cases with periorbital swelling (16%). Endophthalmitis was noted in 1 patient (1%) and retrobulbar optic neuritis (unilateral) was observed in 4 patients (4%). Conclusion: Covid-19 has innumerable ophthalmological manifestations and sequelae ranging from mild surface disorders to severe ocular morbidities. These may be attributed to the direct effects of the disease or the indirect effects of it. Hence, we recommend all patients of Covid-19 should undergo detailed eye evaluation and screening even post recovery to curtail ocular morbidities especially in terms of development of cataract, glaucoma, vascular occlusions, and the late complication of mucormycosis.
