Summary
Congenital retinal macrovessels can cause reduced macular sensitivity. This case report details reduced sensitivity in the superior macula detected by liquid crystal display (LCD) microperimetry.
Area of Science:
- Ophthalmology
- Retinal Imaging
- Visual Electrophysiology
Background:
- Congenital retinal macrovessels are rare vascular anomalies.
- Macular sensitivity is crucial for detailed visual tasks.
- Microperimetry is a key tool for assessing retinal sensitivity.
Observation:
- A case report of a patient with a congenital retinal macrovessel in the left eye (OS).
- Fundus examination revealed a normal right eye (OD).
- The patient presented with normal visual acuity in both eyes.
Findings:
- Liquid crystal display (LCD) microperimetry demonstrated reduced retinal sensitivity in the superior macula of the affected eye (13.0 dB) compared to the inferior macula (15.0 dB).
- No significant sensitivity difference was observed in the unaffected right eye.
- These findings suggest a localized impact of the macrovessel on retinal function.
Implications:
- Congenital retinal macrovessels may lead to relative angioscotomas.
- Reduced macular sensitivity can occur secondary to these vascular anomalies.
- Microperimetry can detect functional deficits associated with retinal vascular variations.
