Ranibizumab for vascularized pigment epithelial detachment: 1-year anatomic and functional results.

PURPOSE: To assess the anatomical and functional efficacy of ranibizumab on vascularized pigment epithelial detachment (V-PED) secondary to neovascular age-related macular degeneration (nAMD). METHODS: One hundred and nine patients (116 eyes) were retrospectively selected from medical records of 2097 patients who benefited from intravitreal injection between January 2011 and June 2013 in a tertiary-care University-based Department of Ophthalmology. Inclusion criteria were: nAMD, treatment-naive eyes, presence of V-PED higher than 250 µm, intravitreal ranibizumab with a loading phase, followed by a pro-re-nata regimen, and 1-year follow-up. Baseline characteristics and type of choroidal neovascularization (CNV) were analyzed. PED height, central macular thickness (CMT) and best-corrected visual acuity (BCVA, logMAR) were measured at baseline, months 3, 6 and 12. RESULTS: CNV was of type 1 in 91 eyes (78.4 %), type 2 in seven (6 %), type 3 in six (5.2 %), and polypoidal choroidal vasculopathy in 12 (10.3 %). Mean CMT at baseline was 572.1 µm and decreased to 396.6 µm (p < 0.0001) at 12 months. Mean height of PED was 458.2 µm at baseline and 306.8 µm (p < 0.0001) at 12 months. Mean BCVA improved from 0.46 at baseline to 0.39 at 12 months (p = 0.013). CONCLUSIONS: Treatment with ranibizumab improved visual and anatomical outcome in nAMD patients with V-PED.

En face enhanced depth imaging optical coherence tomography features in adult onset foveomacular vitelliform dystrophy.

BACKGROUND: Our purpose was to describe the different morphological features in adult onset foveomacular vitelliform dystrophy (AOFVD), using en face enhanced depth imaging (EDI) spectral-domain optical coherence tomography (SD-OCT). METHODS: Thirty eyes of 22 consecutive patients presenting with diagnosis of AOFVD were enrolled. Diagnosis of AOFVD was concluded based on fundus examination, autofluorescence imaging, fluorescein angiography and SD-OCT. En face OCT imaging was obtained with the Spectralis EDI SD-OCT; 97 inverted sections (nine averaged B-scans per image) were acquired. RESULTS: On en face OCT, vitelliform lesions appeared as regular concentric rings of different reflectivity. From the periphery to center of the ring, we observed: (1) the hypereflective ring representing the inner segment/ outer segment (IS/OS) junction, which was continuous in 23 out of 30 eyes, and (2) a well-detectable hyporeflective ring between the IS/OS junction and vitelliform material in 20 out of 30 eyes; the innermost composant of the lesion was hypereflective, and it corresponded to vitelliform material. In eight out of 30 eyes, a hyporeflective "croissant"-shaped lesion with inferior concavity in the upper part of the hyperreflective material was present. Hypereflective retinal pigment epithelium (RPE) elevations or bumps were detected in 25 out of 30 eyes. These areas of focal RPE thickening or bumps appeared to be intensely hypereflective on infrared reflectance imaging. CONCLUSION: En face imaging of the retina helps visualizing the distribution of vitelliform material in AOFVD. The sedimentation of vitelliform lesions is characterized by a upper "croissant"-shaped hypoflectivity. The bumps/thickening of RPE appeared as hypereflective lesions on IR imaging.
