Hemicentral retinal artery occlusion in young adults
I would like to correct my comment in my original letter, commenting on the article published by Rishi et al., which is “this condition is unlikely to occur on ground of embryology, as the central retinal artery develops from a single hyaloid artery and enters the lamina cribrosa.” Now, my attention has been drawn by Dr. S S Hayreh that on certain occasions it is possible to have two central retinal arteries. Therefore, it is possible to have the condition as described by Rishi et al.
