[Possible recurrent multiple evanescent white dot syndrome and chroroidal neovascularization]

Area of Science:

• Ophthalmology
• Retinal Diseases
• Inflammatory Eye Conditions

Background:

• Multiple evanescent white dot syndrome (MEWDS) is typically an inflammatory condition with a favorable visual prognosis.
• Recurrent and bilateral presentations of MEWDS are uncommon.
• Subretinal neovascularization (SRNV) is a rare complication of MEWDS.

Observation:

• A patient experienced three bilateral episodes of MEWDS over nine years.
• Thirteen years after the initial MEWDS diagnosis, the patient developed SRNV.
• The SRNV responded well to photodynamic therapy, resulting in a final visual acuity of 20/40.

Findings:

• This case highlights an unusual presentation of recurrent, bilateral MEWDS.
• The development of SRNV in the context of MEWDS is exceptionally rare.
• Photodynamic therapy proved effective in managing the SRNV associated with MEWDS.

Implications:

• Long-term follow-up is recommended for patients with MEWDS.
• Early detection and management of SRNV are critical for preserving vision in MEWDS patients.
• This case expands the understanding of potential complications and long-term outcomes in MEWDS.
