Diabetic Retinopathy, trauma
DIABETIC RETINOPATHY
In this report, we analyse participant baseline demographics, trauma history and ocular history including baseline biomicroscopic ocular exam results prior to surgery. The baseline eye exam included the Early Treatment Diabetic Retinopathy Study (ETDRS) letter score measured using the standard validated ETDRS chart at a starting distance of 4 m in the eye operated on. If 20 or more letters were read at 4 m, 30 was added to the total letter score. If less than 20 letters were read correctly at 4 m then the distance was moved to 1 m and the number of letters read at 1 m formed the total score. If no letters were seen at 1 m then the score is 0 and test for Counting Fingers, Hand Movements and Light Perception.
