Summary
Optical coherence tomography (OCT) reveals a novel finding in pathologic myopia (PM). This study suggests reclassifying peripapillary detachment in PM as peripapillary intrachoroidal cavitation based on OCT imaging.
Area of Science:
- Ophthalmology
- Medical Imaging
Background:
- Pathologic myopia (PM) is associated with various posterior segment abnormalities.
- Peripapillary detachment in pathologic myopia (PDPM) is a recently described condition.
Observation:
- An observational case report detailing findings in a 69-year-old woman with bilateral PDPM.
- Clinical presentation included bilateral yellow-orange peripapillary lesions at the inferior border of the myopic conus.
Findings:
- Optical coherence tomography (OCT) demonstrated a large intrachoroidal hyporeflective space.
- This space was located below the retinal pigment epithelium (RPE) plane.
- No RPE detachment was observed; the RPE appeared flat.
Implications:
- OCT findings challenge the existing terminology for this anomaly.
- The proposed term 'peripapillary intrachoroidal cavitation' may better describe the OCT appearance.
- This reclassification could refine understanding and diagnosis of posterior segment changes in pathologic myopia.
