Postoperative microstructural re-modelling and functional outcomes in idiopathic full thickness macular hole

Area of Science:

• Ophthalmology
• Retinal Imaging
• Surgical Outcomes

Background:

• Idiopathic full-thickness macular hole (FTMH) affects vision and requires surgical intervention.
• Understanding factors influencing surgical success is crucial for patient management.

Purpose of the Study:

• To analyze the impact of macular hole indices and postoperative microstructural retinal changes on functional outcomes in FTMH patients.
• To correlate pre- and post-operative optical coherence tomography (OCT) findings with visual acuity.

Main Methods:

• Prospective analysis of OCT scans from 36 eyes with idiopathic FTMH before and after surgery.
• Evaluation of macular hole indices, ellipsoid zone (EZ) and external limiting membrane (ELM) integrity, retinal defects, and cystoid resolution.

Main Results:

• Macular hole indices (MHI, THI, HFF) significantly correlated with hole closure types.
• Intact ELM and EZ postoperatively were associated with better best-corrected visual acuity (BCVA).
• Absence of outer and inner retinal defects, and cystoid resolution correlated with improved BCVA.

Conclusions:

• Macular hole indices are key predictors of surgical closure type.
• Postoperative outer retinal layer regeneration and defect resolution are critical for visual recovery.
• ELM integrity is essential for EZ regeneration, with no new inner retinal defects observed within 3 months.
