[The role of Stratus OCT in anti-VEGF therapy. Qualitative and quantitative assessment of neovascular AMD]. / Die Rolle des Stratus-OCT bei der Anti-VEGF-Therapie : Qualitative und quantitative Beurteilung bei neovaskulärer AMD.

ABSTRACT

BACKGROUND: The evaluation of OCT3 during anti-VEGF therapy. METHODS: A total of 29 patients with choroidal neovascularization secondary to AMD received 3 intravitreal injections of ranibizumab. OCT examination and visual acuity testing (ETDRS) were performed before therapy onset, after 1 week and after 1, 2 and 3 months. RESULTS: The central retinal thickness (CRT) was assessed correctly by OCT in 128 out of 145 measurements. There was a distinct (84%) but not significant correlation between decrease in central retinal thickness and increase in visual acuity. Incorrect retinal layer segmentation and inadequate CRT measurements were a significant technical limitation. CONCLUSION: During anti-VEGF therapy, OCT allows documentation and quantification of morphologic retinal changes and in most cases also for an estimation of functional improvement.
