Two-Year Anatomical and Functional Outcomes After Macular Hole Surgery: A Prospective, Controlled Study
Ophthalmic Surgery, Lasers & Imaging Retina
|October 16, 2015
Summary
Macular hole surgery patients showed thinning in the retinal nerve fiber layer and ganglion cell layer two years post-operation. Larger retinal defects predicted better visual recovery after macular hole repair.
Area of Science:
- Ophthalmology
- Retinal Imaging
- Surgical Outcomes
Background:
- Macular hole (MH) surgery aims to restore vision.
- Understanding long-term anatomical and functional changes is crucial.
Purpose of the Study:
- To assess 2-year anatomical and functional outcomes following MH surgery.
- To identify predictors of visual recovery after MH repair.
Main Methods:
- Spectral-domain optical coherence tomography (SD-OCT) was used to analyze retinal layers.
- Measurements included retinal nerve fiber layer (RNFL), external limiting membrane (ELM), inner segment/outer segment (IS/OS) junction, cone outer-segment tips (COST) line, and ganglion cell inner plexiform layer (GCIPL) thickness.
- Evaluations were performed preoperatively and at 3, 12, and 24 months postoperatively in 10 patients.
Main Results:
- Eyes undergoing MH surgery exhibited thinning in the inferior peripapillary RNFL and average GCIPL compared to the fellow eye.
- A significant correlation was found between the size of defects in the ELM, IS/OS junction, and COST line and visual recovery.
- Inferior peripapillary RNFL was thinner in the surgical eye (SE) (110 ± 12.2) versus the fellow eye (FE) (123 ± 9.82) (P < .05).
Conclusions:
- Macular hole repair is associated with long-term thinning of the inferior RNFL and GCIPL.
- The size of ELM, IS/OS junction, and COST line defects are significant predictors of visual recovery after MH surgery.
