Inflammation of the middle or inner layers of the eye, including the iris or choroid.
To support a rating based on incapacitating episodes, the most important evidence is a clear record of each clinic visit made specifically to treat your eye condition within the past 12 months. Medical records that show the date of each visit, the provider seen, and the treatment given — such as an injection, a laser procedure, a prescription for immunosuppressants or biologic agents, or another surgical intervention — directly address the visit-count criteria at each rating level.
Records showing fewer than three treatment visits support the 10% criteria. Records confirming at least three visits build toward 20%, at least five toward 40%, and seven or more toward 60%. Pharmacy records, surgical reports, infusion logs, and ophthalmology or rheumatology notes can all help document that a visit was for treatment rather than routine monitoring.
If your condition has also reduced your vision, records of visual acuity testing, visual field testing, or other eye examination findings are relevant to the visual impairment rating path. Statements from you or people who know you describing how flare-ups affect your ability to work or carry out daily activities can help show the severity and frequency of episodes.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
