title: Incidence of Reopening and Variables That Influence Reopening After Macular Hole Surgery.
abstract: Purpose: To evaluate the incidence and variables of reopening of macular holes after macular hole surgery.Methods: Our study included 467 eyes in which macular holes were successfully closed after surgery. Surgical techniques consisted of conventional methods (358 eyes) and scalping methods (109 eyes) with retinal pigment scalping of the macular hole basis added in such cases: reoperation, hole size (more than 0.4 disc diameter), duration of symptoms (more than 2 years). Long term incidence of reopening was predicted by life table method. After we compared reopened cases with non-reopened cases, the variables of gender, stage, biocular occurrence, age, duration of symptoms, hole size, preoperative visual acuity, refraction axial length ratio, and intraoperative retinal tears were used for the multiple regression.Results: Reopening was found in 20 eyes (5.6%) treated by conventional methods and in 10 eyes (9.2%) treated by scalping methods. Survival ratio was 87% for the conventional methods in 6 years and 79% for the scalping methods in 5 years. The variables influencing reopening were as follows: conventional methods: gender (r = 0.065, P =.19), biocular occurrence (r = 0.12, P =.026), and refraction axial length ratio (r = -0.11, P =.045); scalping methods: hole size (r = 0.14, P =.25).Conclusions: Incidence of reopening in scalping methods was high. The variables that influenced reopening after macular hole surgery were biocular occurrence and refraction axial length ratio in conventional methods. The shape of the eye may be related to reopening.
