Introduction The EyeCOPE study characterized noninfectious intermediate posterior, or panuveitis (NIIPPU) before biologic agents were widely available. Methods This retrospective, observational study included adults with NIIPPU attending a routine ophthalmological visit. Data were collected from the study visit and medical records. Results Of 565 patients, 58.8% were female, and the mean age was 41.3 years; 33.8% had idiopathic uveitis and 45.8% had panuveitis. The median time from symptom onset to diagnosis and treatment was 27.0 and 30.5 days, respectively. Patients received immunosuppressants and systemic/local corticosteroids. Most patients experienced substantial decline in ocular function (mean best corrected visual acuity, 0.4 logMAR). Mean total work productivity impairment among employed patients was 31.0%. Most patients reported ocular complications (70.8%) such as vision loss and cataracts. Conclusions Despite treatment, most patients with NIIPPU experienced a decline in ocular function and ocular complications. There is an unmet need for additional NIIPPU treatment, such as targeted monoclonal antibodies.
