Therapies targeting Frizzled-7/β-catenin pathway prevent the development of pathological angiogenesis in an ischemic retinopathy model.

Retinopathies remain major causes of visual impairment in diabetic patients and premature infants. Introduction of anti-angiogenic drugs targeting vascular endothelial growth factor (VEGF) has transformed therapy for these proliferative retinopathies. However, limitations associated with anti-VEGF medications require to unravel new pathways of vessel growth to identify potential drug targets.

Spontaneous rupture of chorioretinal coloboma in an 8-year-old child is treated by temporal fascia graft.

We report the rare case of an 8-year-old boy with spontaneous scleral perforation secondary to an isolated congenital chorioretinal coloboma. Visual acuity was 20/200 and examination revealed severe hypotony with subcapsular cataract, complete exudative retinal detachment, hypotonous optic nerve swelling, and hypotony retinal fold. In the temporal periphery, there was a chorioretinal coloboma with a central full-thickness defect.

Multimodal Imaging of Reticular Pseudodrusen in a Population-Based Setting: The Alienor Study.

Purpose: To document reticular pseudodrusen (RPD) using multimodal imaging in French elderly subjects.

Methods: A total of 494 subjects (970 eyes) aged 77 years or more, from the Alienor study, were examined in 2011 and 2012. Reticular pseudodrusen were defined as definite if they were present with at least two imaging methods among color retinal photographs, macular cube (20° × 15°) of spectral-domain optical coherence tomography (SD-OCT), fundus autofluorescence (FAF), and infrared reflectance (IR).
