Evaluation of central retinal sensitivity after vitrectomy with removal of choroidal neovascular membrane for age-related macular degeneration

摘要

PURPOSE: To evaluate retinal sensitivity in patients with age-related macular degeneration (AMD) before and after surgery. METHODS: Seven consecutive patients with AMD underwent vitrectomy with removal of choroidal neovascular membrane(CNV). Static microperimetry using a scanning laser ophthalmoscope(SLO) was performed before and after surgery. Central dense scotoma size was measured. RESULTS: Retinal sensitivity improved in all cases. Mean size of the central dense scotoma was decreased by 42%(range 14-62%). CONCLUSION: The results suggest that vitrectomy with removal of CNV can improve the central retinal sensitivity.
