[Variables that influence visual acuity after macular hole surgery]
Purpose:
To evaluate the variables that influence visual acuity and visual improvement after macular hole surgery.
Methods:
Our study included 421 eyes in which maculor holes were successfully closed after surgery and followed up at least 1 year after the last surgery. Surgical techniques were conventional methods (Group 1: 350 eyes) with retinal pigment scalping of the macular hole basis added in the refractory cases (Group 2: 71 eyes). The variables used for the multiple regression were gender, age, preoperative visual acuity, hole stage, duration of symptoms, hole size, and axial length.
Results:
The variables that most influenced postoperative visual acuity were as follows: Group 1: gender (r = -0.011, p = 0.016), age (r = -0.17, p = 0.005), preoperative visual acuity (r = 0.51, p < 0.0001), duration of symptoms (r = -0.015, p < 0.0001), and axial length (r = -0.090, p = 0.045). Group 2: age (r = -0.18, p = 0.047), and preoperative visual acuity (r = 0.47, p < 0.0001).
Conclusions:
The variables that influenced visual acuity and visual improvement after macular hole surgery were common. In Group 1: gender, age, preoperative visual acuity, duration of symptoms, and axial length; in Group 2: age and preoperative visual acuity.
