Objective To observe the clinical effect of photodynamic therapy (PDT）based comprehensive treatment for choroidal neovascularization (CNV) in patients with multifocal choroiditis (MC). Methods Nine eyes of 8 MC patients (7 females and 1 male) with CNV who had undergone PDT based comprehensive treatment were enrolled in this study. The patients aged from 25 to 54 years with the mean of (41.8 plusmn;10.6) years. The examinations of best-corrected visual acuity (BCVA), slit lamp microscope, indirect ophthalmoscopy, fundus fluorescein angiography and optical coherence tomography were performed. The BCVA ranged from 20/333 to 20/50 (mean logMAR 0.68 plusmn;0.32). The mean CNV area was (0.767 plusmn;0.445) mm2. The central retinal thickness (CRT) was (355.2 plusmn;65.2) mu;m. Among the 8 patients,4 eyes received only PDT, 2 eyes received PDT and oral corticosteroid, 1 eye received PDT and intravitreal injection of 1.25 mg bevacizumab, 2 eyes received PDT and subtenon injection of 40 mg triamcinolone acetonide. The follow-up period ranged from 3 to 22 months, with the mean of (14.0 plusmn;5.7) months. The BCVA, mean CNV area and CRT before and after treatment were analyzed. Results By the end of last visit, the BCVA improved to 20/250 to 20/25 (mean logMAR 0.58 plusmn;0.37), but the difference was not statistically significant (t=1.890, P=0.095). Visual acuity improved 3 lines in 3 eyes (33.3%), improved 1.5 lines in 1 eye (11.1%), unchanged in 4 eyes (44.4%) and decreased 1.5 lines in 1 eye (11.1%). The mean CNV area decreased to (0.684 plusmn;0.371) mm2, but the difference was not statistically significant (t=0.996, P=0.349). The CRT decreased to (295.3 plusmn;79.4) mu;m, but the difference was not statistically significant (t=2.242, P=0.055). Conclusion PDT can stabilize visual acuity in patients with subretinal CNV secondary to MC, especially when combined with intravitreal injection of antivascular endothelial growth factor drugs or steroid.
