SECONDARY MULTIPLE EVANESCENT WHITE DOT SYNDROME AFTER BLUNT TRAUMA

Area of Science:

• Ophthalmology
• Retinal Diseases
• Neuro-ophthalmology

Background:

• Multiple Evanescent White Dot Syndrome (MEWDS) is an idiopathic inflammatory condition affecting the outer retina.
• While often unilateral and self-limiting, its association with specific triggers is being increasingly recognized.

Purpose of the Study:

• To document a unique case of secondary unilateral MEWDS.
• To highlight the delayed onset of MEWDS following blunt ocular trauma.

Main Methods:

• An observational case report detailing a single patient's presentation and clinical course.
• Ophthalmic examination, including best-corrected visual acuity (BCVA) and optical coherence tomography (OCT).

Main Results:

• A 25-year-old male developed MEWDS two years after blunt force trauma to the eye.
• Initial symptoms included decreased vision, iritis, commotio retinae, and pigment epithelial detachment.
• Subsequent examination revealed characteristic white dot lesions, ellipsoid zone disruption, and significant visual recovery within two months of observation.

Conclusions:

• This case represents a significantly longer latency period between blunt eye trauma and the onset of MEWDS than previously reported.
• The findings suggest that blunt trauma may be a trigger for MEWDS even with a substantial delay.
