Central retinal vein occlusion and branch retinal vein occlusion in the same eye
A 55-year-old hypertensive male, who had previously been diagnosed to have right eye inferio-temporal (IT) branched retinal vein occlusion (BRVO) 3 years ago and received treatment for the same, presented with sudden loss of vision in the same eye. Diffuse multiple flame-shaped hemorrhages along with tortuous vessels were noted in all three quadrants except the IT quadrant which had sclerosed vessels. The patient was diagnosed to have a fresh episode of central retinal vein occlusion (CRVO) in the same eye sparing the area of BRVO.
The fundus image [Fig. 1] illustrates a rare presentation of CRVO and BRVO in the same eye. Hayreh et al. propose that around 2.5% have chances of developing recurrent RVO (CRVO or BRVO) in the same affected eye. A vigilant follow up is necessary for all the RVO patients as they are prone to second attack.
