[Predictive parameters for anatomical surgical success in full-thickness macular holes : A retrospective evaluation of 391 eyes].

Abstract

Background: Full-thickness macular hole (FTMH) is a rare disease. Not all FTMHs can be closed by primary surgical intervention.

Objective: This work aims to characterize a large patient population with FTMHs and to detect possible predictive factors for anatomical treatment success.

Materials and methods: The study comprises a retrospective analysis of all consecutive idiopathic macular holes between March 2008 and June 2019 at the University Eye Hospital Cologne. Epidemiologic data, preoperative parameters (size of the FTMH), and surgical technique were examined in relation to the closure rate following primary surgery.

Results: The anatomical closure rate for idiopathic FTMH after primary surgery was 83.6%. No association between age, gender, and lens status and closure rate could be shown. Regarding anatomical surgical success, the favorable prognostic factors identified were a small FTMH size, short symptom duration, performance of transconjunctival 23-gauge vitrectomy, and application of the inverted flap technique of the internal limiting membrane (ILM).

Conclusion: Surgical treatment represents a valuable treatment option for patients with macular holes due to good prospects of success. Prompt intervention after diagnosis using 23-gauge vitrectomy and an ILM flap with gas tamponade seems to result in the most favorable outcomes.
