Purpose: Multiple evanescent white dot syndrome (MEWDS) is a self-limiting disease in which reduced visual acuity and retinal changes recover without treatment. It also shows visual field defects including an enlarged blind spot of Mariotte. However the final outcome of the field change has rarely been documented. We therefore retrospectively studied the visual field change in eyes with MEWDS by reviewing the multiple results of automated static perimetry recorded in the clinical course of the disease.
Subjects: We reviewed the clinical course of five eyes with MEWDS using the multiple recordings of the Humphrey central 30-2 program taken during their clinical course.
Results: The initial findings of perimetry included an enlarged blind spot of Mariotte, depression of the central field, and paracentral scotoma. These field defects recovered within 2 weeks to 4 months.
Conclusion: Visual field defects as well as vision and retinal changes recover without treatment in eyes with MEWDS.
