- 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
