INFLUENCE OF FOVEAL GLIAL TISSUE AFTER MACULAR HOLE SURGERY ON OUTER RETINAL RESTORATION AND VISUAL ACUITY

Area of Science:

• Ophthalmology
• Retinal Surgery
• Visual Neuroscience

Background:

• Macular hole (MH) surgery aims to restore vision by closing the retinal defect.
• The role of foveal glial tissue in post-surgical outcomes remains incompletely understood.

Purpose of the Study:

• To investigate the impact of foveal glial tissue on anatomical and functional results after macular hole surgery.
• To determine if glial tissue size influences outer retinal layer restoration and visual acuity improvement.

Main Methods:

• 141 eyes undergoing successful MH vitrectomy were analyzed.
• Pre- and postoperative best-corrected visual acuity and outer retinal defect length were evaluated.
• Multiple regression analysis assessed the influence of glial tissue size, surgical technique, and high myopia.

Main Results:

• Foveal glial tissue significantly limited outer nuclear layer, external limiting membrane, and ellipsoid zone restoration.
• Glial tissue also significantly impaired best-corrected visual acuity improvement post-surgery.
• Surgical technique and high myopia did not significantly affect these restorative processes.

Conclusions:

• Foveal glial tissue is a significant factor that attenuates retinal layer restoration and visual acuity improvement after macular hole surgery.
• Reducing or managing foveal glial tissue may be crucial for optimizing surgical outcomes in MH repair.
