AIM
To analyse
the visual results obtained in the treatment of subretinal choroidal
neovascularisation (CNV) in patients with high myopia by vitrectomy and
extraction of the neovascular membrane.
METHODS
22 eyes of 22 patients with high myopia (>
6 dioptres and/or axial length >26 mm)
with subfoveal CNV treated by extraction of the CNV were
analysed
retrospectively. The patients' mean age was 60.27 (SD 16.41) years (range 32-83 years). The mean follow up was 29.3 (9.9) months (range 12-42 months).
RESULTS
Best corrected
visual acuity (BCVA) preoperatively was 0.09 (0.07) (range 0.01-0.3).
After treatment BCVA was 0.12 (0.10) (range 0.01-0.4), a difference
without statistical significance (p=0.03, Student's
t test paired data). In four cases the CNV recurred, in three cases cataract developed that required extraction, and in one case retinal detachment occurred in the early postoperative period. Topical treatment was necessary in two cases to lower the
intraocular pressure.
CONCLUSIONS
The
treatment of subfoveal CNV in highly myopic patients by surgical
removal by vitrectomy does not achieve any significant improvement of
the BCVA.
