Correlation between central retinal thickness after successful macular hole surgery and visual outcome

Area of Science:

• Ophthalmology
• Retinal Surgery
• Optical Coherence Tomography

Background:

• Idiopathic macular holes (MH) are a common cause of visual impairment.
• Vitreous surgery is a standard treatment for MH closure.
• Predicting visual outcomes after MH surgery is crucial for patient management.

Purpose of the Study:

• To investigate the relationship between central retinal thickness (CRT) post-vitreous surgery and final visual acuity in patients with idiopathic macular holes (MH).

Main Methods:

• Prospective study of patients undergoing MH surgery.
• Analysis of best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) parameters (CRT, MH diameter) pre- and postoperatively.
• Regression analysis to determine correlations between OCT parameters and visual outcomes.

Main Results:

• Successful MH closure was achieved in all cases.
• Postoperative BCVA improved, and CRT decreased over time.
• A significant positive correlation was found between CRT at 1 month and visual acuity at 12 months (P < 0.0001).
• MH diameter correlated positively with early CRT and negatively with postoperative visual acuity.

Conclusions:

• Early postoperative CRT (at 1 month) is linked to preoperative MH size and long-term visual acuity.
• Elevated CRT in the early stages after MH surgery may indicate a favorable visual prognosis.
