[Prognostic factors for idiopathic macular hole surgery: Report of 107 eyes (Approach by univariate statistical analysis)]

Abstract

Purpose: To identify prognostic factors influencing the success of idiopathic macular hole surgery, including initial visual acuity, hole size and stage, and type of gas used for tamponade.

Patients and methods: Retrospective single-center descriptive analysis of all patients with an idiopathic macular hole operated by the same surgeon, treated in the ophthalmology department of Mulhouse hospital, between January 2004 and July 2014. Patients whose functional and anatomical results could be confounded by the coexistence of other ocular pathologies and patients with secondary macular holes were excluded.

Results: We included and followed 107 eyes of 104 patients for at least 6 months. Initial closure after the first surgery was obtained in 92 eyes (85.98 %), allowing 2 groups to be defined, the cases of success and failure. Initial visual acuity, hole size, stage according to Gass, Gaudric and IVTS classifications, and presence or absence of a PVD, were statistically significant prognostic factors (P<0.05) CONCLUSION: Our univariate statistical analysis identified multiple prognostic factors. These factors may predict success and the choice of surgical technique, including whether to peel the internal limiting membrane, the choice of gas for tamponade, and postoperative positioning.
