Background:
This study investigates a new instrument, called the Microperimeter-1 (MP-1), which maps areas of retinal sensitivity, in a series of patients with multiple evanescent white dot syndrome (MEWDS).
Methods:
A retrospective observational case series from a private retina practice, in which 3 patients with a diagnosis of MEWDS underwent testing with the MP-1.
Results:
All 3 patients in this series showed an enlarged blind spot on MP-1 testing.
Interpretation:
Microperimetry is a useful tool in visual field testing for patients with MEWDS. The MP-1 allows retinal sensitivity mapping to be displayed on a fundus photograph, which permits correlation of scotomata with retinal pathology.
