Choroidal Neovacularization in Pathologic Myopia: Three-Year Reult After Photodynamic Therapy

Purpoe To examine whether the encouraging functional reult one year after photodynamic therapy (PDT) can be maintained up to three year. Deign Propective interventional cae erie. Method Highly myopic eye that had been treated with PDT for ubfoveal choroidal neovacularization and had been oberved at leat 36 month were included. Ditance acuity (Early Treatment of Diabetic Retinopathy chart), reading acuity (Jaeger chart), 10-degree tatic threhold perimetry, fluorecein angiography, and optical coherence tomography were performed. The main outcome meaure were the difference of the value among the baeline and the month 12 and the month 36 examination. Reult Twenty eye of 18 patient were included: 15 patient were female, and 3 patient were male. The average age wa 64 year (range, 36 to 85 year). The mean ditance acuity wa 43 letter at baeline and 53 letter after 12 month and after 36 month. The mean reading acuity changed from mean J10.8 to mean J8.1 after 12 month and to mean J9.85 after 3 year. The mean defect decreaed from mean 13.5 dB at baeline to mean 12.5 dB after 12 month and mean 11.2 dB after 36 month. The maximum retinal thickne decreaed from mean 360 μm at baeline to mean 259 μm after one year and mean 238 μm after 36 month. Concluion Ditance acuity and central viual field howed tabilization after the month 12 examination up to the month 36 examination. The reading acuity decreaed between the month 12 and the month 36 examination, which might be related to an increae of retinal atrophy.
