One of the most important differentials for painless sudden loss of vision is CRVO (Central retinal vein occlusion). It is one of the leading diseases causing vision loss especially in elderly population. However, bilateral simultaneous CRVO in a young patient with no other co morbidities is rare. This case illustrates a young male of 40 years with no well-known comorbidities who experienced sudden onset diminution of vision in right eye followed by left eye in 2 weeks gap. No history of smoking, diabetes, hypertension, dyslipidemia or any other systemic disorders. Patient is not on any topical or systemic medications. There was no significant family history. On evaluation of right eye, the BCVA (best corrected visual acuity) was 6/36 and left eye was finger counting 3 meters. Intra ocular pressure in both eyes was 18 mm Hg. Anterior segment showed all normal findings. Dilated fundus evaluation in both eyes showed multiple superficial and deep hemorrhages with hard exudates and macular edema. OCT (Optical Coherence tomography) displayed macular edema in both eyes. Blood investigations showed all values within normal limits except Vitamin D levels which were found to be deficient.
