AIM: Evaluation of the proportion of patients affected by subfoveal choroidal neovascularization secondary to age-related macular degeneration who are non-respondent to intravitreal ranibizumab injections (IVRI). METHODS: Patients received 3 monthly IVRI, with monthly retreatments, in accordance with a pro re nata scheme (fluid on optical coherence tomography, leakage on fluorescein angiography, new haemorrhages). Non-responders were classified as follows: functional non-responder (best-corrected visual acuity worsening by a minimum of 2 ETDRS lines); anatomical non-responder (central foveal thickness not decreasing by at least 10% compared with baseline value); complete non-responder (both anatomical and functional non-responder criteria apply)...

In macular spectral domain optical coherence tomography (SD-OCT) volumes, detection of the foveal center is required for accurate and reproducible follow-up studies, structure function correlation, and measurement grid positioning. However, disease can cause severe obscuring or deformation of the fovea, thus presenting a major challenge in automated detection. We propose a fully automated fovea detection algorithm to extract the fovea position in SD-OCT volumes of eyes with exudative maculopathy. The fovea is classified into 3 main appearances to both specify the detection algorithm used and reduce computational complexity...
