At a Glance
Category Detail
Condition Key Mechanisms Target Population Patients with persistent visual disturbances for more than 3 months and associated symptoms. Care Setting
Key Highlights
Symptoms include continuous visual static, palinopsia, photophobia, nyctalopia, and tinnitus. Prevalence of comorbidities: migraine (50-72%), tinnitus (62-75%), anxiety/depression (up to 35%). Normal neuro-ophthalmologic findings despite persistent symptoms. Escitalopram showed subjective improvement in visual static intensity, but overall efficacy is low (6-7% improvement in patients). Nonpharmacologic approaches like cognitive behavioral therapy and colored filter lenses may reduce symptoms. Guideline-Based Recommendations
