Grand Rounds Jinghua Chen, MD, PhD October 21, 2016 Department of Ophthalmology and Visual Sciences History CC: 29 yo young male complained of sudden blurred vision in right eye. HPI: This is a 29 yo young male from Peru who came to
US two months ago to study. Two nights ago he stayed very late to study for an exam. He noticed that he could only see periphery with right eye, central vision was very blurry. Past Medical History POH: Refractive error OU

Multiple Evanescent White Dot Syndrome (MEWDS) First described by Jampol L. M in 1984 Young, healthy women in the second to fourth decades of life Symptoms: a viral prodrome unilateral, acute painless vision loss

An orange-yellow fovea with granularity Vitreous inflammation, optic disc edema. Multiple Evanescent White Dot Syndrome (MEWDS) FA reveals early punctate hyperfluorescence in a wreath-like pattern and late staining
OCT: Discontinuities in inner segmentouter segment junction Immune-mediated vascular inflammation that affects various retinal layers, including the choroid, RPE and photoreceptors.2,5 Early identification MEWDS is generally benign APMPPE may be associated with systemic vasculitis.
MCP has a chronic recurrent course responsive to anti-inflammatory therapy. PIC a significant risk of choroidal neovascular membrane formation References 1.
