Retinal vein occlusion (RVO) is a partial or total blockage in a vein that drains blood from the retina, often called an "eye stroke". The retina is a layer of tissue at the back of the eye that helps translate light into images you can see. A blockage in a retinal vein prevents blood from leaving the retina. This can lead to complications, including raised pressure in the eye and swelling, leading to sudden blurry or lost vision. There's no current safe way to unblock the vein. However, treatment can manage complications and protect a patients' vision.

Qdata Retinal Vein Occlusion is a curated, high-quality dataset from the American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight) that provides an accurate way to mine EHR data to analyze patients with retinal vein occlusion, as well as their associated clinical outcomes through clinical notes and images.

Qdata Retinal Vein Occlusion by Verana Health is a research-ready, fit-for-purpose real-world dataset that can be used to analyze patients with RVO and track their outcomes. These outcomes are derived from unstructured and semi structured fields in EHRS and include visual acuity, Snellen test values, and intravitreal agents.
