title: Intravitreal ranibizumab for choroidal neovascularization secondary to angiod streaks. Comparison of the 12 and 24-month results of treatment in treatment-naïve eyes.
abstract: Our aim study was to compare 12 and 24-month results of intravitreal ranibizumab therapy in the management of choroidal neovascularization (CNV) secondary to angioid streaks (ST). This could be of clinical importance helping us planning optimal dosing strategies.
  
  
  
  Over a 7-year period, a consecutive series of treatment-naïve eyes with macular CNV due to AS were treated with intravitreal ranibizumab (0.5 mg). The main outcome measure was changed in best-corrected visual acuity (BCVA) at 12 and 24 months as compared to baseline.
  
  
  
  Twenty eyes completed 24-month therapy and regular follow-up visits. BCVA improved at 12 (0.42±0.26 logMAR) and 24 months (0.44±0.22 logMAR) as compared to baseline (0.75±0.26 logMAR) (p<0.001), but did not change between the 12 and 24-month follow-up (p=0.48). BCVA improved in 15 (75%) and 16 (80%) of the eyes, but in 5 (25%) and 4 eyes (20%) remained unchanged (p=0.71) at 12 and 24 months, respectively.
  
  
  
  These results suggest that during the first year of intravitreal ranibizumab therapy for patients with macular CNV due to AS, BCVA improved in most of the eyes, and was maintained during the second year.
