[Maculopathy with areolar retinal pigment epithelium defects]
Summary
Fenestrated sheen macular dystrophy causes bilateral perifoveolar retinal pigment epithelium defects, leading to metamorphopsia. This rare condition, often asymptomatic, has a good visual acuity prognosis despite no available therapy.
Area of Science:
- Ophthalmology
- Medical Genetics
- Retinal Diseases
Background:
- Maculopathy with retinal pigment epithelium (RPE) defects presents diagnostic challenges, especially in young adults with preserved visual acuity.
- Early and accurate diagnosis is crucial for managing expectations regarding disease prognosis.
Observation:
- A 36-year-old female presented with bilateral perifoveolar RPE defects and metamorphopsia, despite maintaining good visual acuity.
- Symptoms began 8 years prior to presentation, indicating a slowly progressive condition.
Findings:
- Autofluorescence photography and optical coherence tomography (OCT) visualized the perifoveolar RPE defects.
- Functional testing revealed deficits in perimetry, microperimetry, and multifocal electroretinography.
- Clinical presentation and disease course were consistent with fenestrated sheen macular dystrophy.
Implications:
- Fenestrated sheen macular dystrophy is a rare, autosomal-dominant inherited condition.
- While no specific therapy exists, the prognosis for visual acuity is generally favorable.
- This case highlights the importance of advanced imaging and functional testing for diagnosing rare macular dystrophies.
