Retinal Nonperfusion in the Posterior Pole Is Associated With Increased Risk of Neovascularization in Central Retinal Vein Occlusion.

Purpose: To review the definition of ischaemic central retinal vein occlusion (CRVO) and stratify the risk of neovascular complication based on wider areas of visible retinal non-perfusion.

Design: Retrospective consecutive case series and image analysis study.

Methods: Setting: Moorfields Eye Hospital, London, United Kingdom.
