PROGRESSION OF MYOPIC MACULOPATHY IN PATIENTS WITH MYOPIC TRACTION MACULOPATHY AFTER VITRECTOMY

Purpose:To compare the progression of myopic maculopathy with or without vitrectomy in patients with myopic traction maculopathy (MTM).Methods:Seventy-seven eyes with MTM were classified into either the observation group (n = 38) or the vitrectomy group (n = 39). Progression of myopic maculopathy was assessed with fundus photography using infrared images. Progression within stage was evaluated as an increase in the area of atrophic lesions on infrared images using ImageJ software. The rate of progression was compared using the paired t-test.Results:The mean follow-up period was 60.0 +/- 47.5 months. The initial mean stage of myopic maculopathy for the observation group was 1.86 +/- 0.86, and it progressed to 2.00 +/- 0.83 (P = 0.023) at the last visit. For the vitrectomy group, the stage progressed from 1.82 +/- 0.96 to 2.05 +/- 1.09 (P = 0.011). Four eyes (10.5%) in the observation group showed progression at 87.3 months, and seven eyes (17.9%) in the vitrectomy group showed progression at 31.3 months.Conclusion:Surgery in patients with MTM may accelerate the progression of myopic maculopathy. Therefore, care should be taken when considering surgery for patients with MTM.
