The COMS Grading Scheme: Graded Features

Retinal Hemorrhage

All punctuate, blot, or linear hemorrhages are included. Hemorrhages that are clearly subretinal or preretinal are excluded.  Retinal hemorrhages show blocked fluorescence on angiogram.  If an angiogram is not available, red dots on color photographs are called retinal hemorrhages unless the grader feels they represent microaneurysms.
