Purpose:
To analyse results obtained from treatment of choroidal neovascular membranes (CNM) in patients with high myopia after vitrectomy and CNM extraction.
Material And Method:
A prospective study including 9 eyes (9 patients) suffering from high myopia (higher than 6 diopters of myopia and/or axial length of more than 26 mm) and subfoveal CNM treated with vitrectomy and membrane extraction. Mean age was 43.11 S.D. 9.02 years of age (range: 32-58). Mean follow up time was 28.44 S.D. 7.65 months (range: 14-39 months).
Results:
Preoperatory best corrected visual acuity (BCVA) was 0.09 S.D. 0.05 (range: 0.01-0.2). Postoperatory BCVA resulted in 0.15 S.D. 0.09 (range: 0.1-0.4). Differences did not show statistical signification (p= 0.09, Student T test). One case of membrane recurrence was observed, one case developed increased intraocular pressure and cataract requiring extraction; another presented increased intraocular pressure in the early postoperative period.
Conclusion:
Extraction of CNM in high myopia using vitrectomy does not show significant improvements in BCVA.
