Multiple Evanescent White Dot Syndrome (MEWDS)
A 45-year-old female presented with complaints of blurred vision in the left eye for 1 week. She also had a temporal field defect in her left eye. Her corrected vision was 6/5 in the right eye and 6/12 in the left eye. Intraocular pressure was 18 mmHg in both eyes. Both anterior segments were normal. There were faint scattered white dots over the left macular mid-periphery (Fig. 13.1). A temporal scotoma was also noted in the left eye according to the visual field examination (Fig. 13.2). OCT examination showed irregular loss of the IS/OS line in the peripapillary zone (Fig. 13.3). She was diagnosed with multiple evanescent white dot syndrome (MEWDS). One month later, her vision recovered to 6/7.5 in the left eye.
