Abnormal adhesion between the eyelid and the eyeball, restricting eye movement.
Because symblepharon is rated based on its specific findings, the evidence that helps most is whatever documents those findings clearly. If the fusion affects how your eyelid closes, records showing lid movement and corneal exposure support a lagophthalmos rating. If visible scarring or disfigurement is present, photographs and clinical descriptions of the affected area support a disfigurement rating. For any visual impairment, eye exam records showing measured visual acuity or visual field loss are relevant.
For incapacitating episodes under the General Rating Formula, treatment records are central. These should show the date of each clinic visit and confirm that the visit was for active treatment — such as systemic immunosuppressants, biologic agents, intravitreal or periocular injections, laser treatments, or surgical procedures — not routine monitoring. A count of qualifying visits within a 12-month period determines which percentage applies. Statements from you or people who know you describing how episodes affected your ability to work or carry out daily activities can help establish the severity and frequency of those episodes.
