Summary
Congenital optic disc pits can lead to serous retinal detachment through fluid flow facilitated by schisis. Optical coherence tomography revealed communication pathways in affected eyes, highlighting the pit
Area of Science:
- Ophthalmology
- Retinal Imaging
- Congenital Eye Anomalies
Background:
- Congenital optic disc pits are rare developmental anomalies.
- Maculopathy associated with optic disc pits can lead to vision loss.
- The exact pathogenesis of fluid accumulation in these cases remains debated.
Observation:
- Optical coherence tomography (OCT) was used to image ten eyes with congenital optic disc pits.
- Patients were categorized into groups based on the presence and resolution of serous macular detachment.
- Detailed cross-sectional retinal images were obtained using high-resolution OCT.
Findings:
- Communication between schisis cavities or subretinal space and the optic nerve pit was evident in eyes with active detachment.
- Cystic degeneration and schisis were observed in the peripapillary retina and macula in most eyes.
- No direct communication between the subretinal space and vitreous cavity was identified.
Implications:
- Schisis formation is integral to serous retinal detachment in congenital optic disc pits.
- Optic disc pits may act as conduits for fluid, contributing to retinal pathology.
- OCT imaging provides valuable insights into the pathogenesis of maculopathy associated with optic disc pits.
