This is a case report of central retinal vein occlusion (CRVO) associated with COVID-19 treated with oral aspirin therapy. A 56-year-old woman reported decreased vision in her left eye. Her left eye vision was 6/18, N10. Anterior segment was within normal limits. Left eye fundus was suggestive of CRVO and macular oedema. Optical coherence tomography showed cystoid macular oedema and neurosensory detachment. Blood work-up revealed elevated D-dimer levels and erythrocyte sedimentation rate (ESR). She was started on treatment with low-dose aspirin 150 mg/day. After 1 month, her vision improved to 6/6, N6. Left eye fundus showed reduced retinal haemorrhages and complete resolution of macular oedema. Her repeat blood work-up showed reduced D-dimer and ESR levels. The patient was asked to be reviewed after 3 months. This case highlights that specific treatment for reducing the hypercoagulable state caused by COVID-19 with oral aspirin therapy can result in complete resolution of CRVO macular oedema.

Background To report spectral domain optical coherence tomography (SDOCT) imaging findings in type 2 macular telangiectasia (MacTel) and correlate them with clinical stages and visual acuity. Methods This retrospective, cross-sectional study included type 2 MacTel cases who underwent SDOCT imaging with Spectralis machine. Macular SDOCT images were analysed. Imaging features were tested for correlation with different clinicals stages and visual acuity. Results 212 eyes of 108 type 2 MacTel patients were included. Hyperreflective middle retinal layer (87%) was the most frequently detected abnormality. This was followed by inner retinal cavities (49%), outward bending of inner retinal layers (35%), retinal pigment clumps (35%) and foveal contour irregularity (31%). Hyperreflective middle retinal layers (p < 0.001), inner (p = 0.032) and outer retinal (p = 0.002) cavities and internal limiting membrane drape (p = 0.031) were associated with poor vision in non-proliferative group and presence of retinal pigment clumps (p = 0.002), subretinal fluid (p = 0.037) and foveal contour irregularity (p < 0.001) were associated with poor vision in proliferative group. Conclusion The described SDOCT features are practical for the diagnosis and staging in type 2 MacTel. Presence of hyperreflective middle retinal layers, hyporeflective inner and outer retinal cavities and internal limiting membrane drape were associated with poor vision in the non-proliferative group while retinal pigment clumps and subretinal neovascular membrane were associated with proliferative group and poor vision. Further long-term studies are required to describe the progressive and sequential changes on SDOCT.
