Disease or damage to the retina or macula that may affect central vision.
To support a rating based on incapacitating episodes, records that clearly show the date of each clinic visit and confirm the visit was for treatment of your eye condition are central. Treatment notes, operative reports, injection logs, and pharmacy records documenting systemic immunosuppressants or biologic agents all help establish both the number of visits and the nature of the treatment within the past 12 months. To support a rating based on visual impairment, you would need evidence of reduced visual acuity or visual field loss measured through formal eye examinations, because VA uses specific acuity and field charts under 38 CFR 4.75–4.78. Statements from you or people who know you describing how your vision or treatment schedule affects your ability to work, drive, read, or carry out daily tasks can help show the overall impact of the condition. Because VA uses whichever method produces the higher rating, having complete records on both visual testing and treatment visits gives the fullest picture of your condition.
