Summary
Inner retinal dimples are common after internal limiting membrane peeling surgery. These dimples enlarge over 12 months post-surgery before decreasing in size, with no impact on visual acuity.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Optical Coherence Tomography
Background:
- Internal limiting membrane (ILM) peeling is a common surgical technique for macular hole repair.
- The morphologic consequences of ILM peeling on the inner retina are not fully understood.
Purpose of the Study:
- To characterize the morphology and evolution of inner retinal dimples after ILM peeling using spectral domain optical coherence tomography (SD-OCT).
- To assess the impact of these dimples on visual outcomes.
Main Methods:
- Retrospective analysis of SD-OCT scans from 43 eyes undergoing macular hole surgery with ILM peeling.
- Evaluation of dimple presence, location, dimensions, and changes over time.
- Comparison of preoperative and postoperative visual acuity.
Main Results:
- Inner retinal dimples were observed in 86% of eyes post-surgery.
- Dimples were most frequent in the inferotemporal quadrant and showed significant enlargement during the first 12 months.
- Postoperative visual acuity improved significantly compared to preoperative levels, with no apparent correlation to dimple presence or size.
Conclusions:
- Inner retinal dimples are a frequent finding after ILM peeling without staining.
- Dimple evolution involves initial enlargement followed by a gradual decrease in size.
- These dimples do not appear to adversely affect visual acuity outcomes.
