PURPOSE: To determine the relationship between different spectral domain optical coherence tomography (SD-OCT) signs of retinal ischemia in acute central retinal vein occlusion (CRVO) and whether they predict anterior segment neovascularization (ASNV). DESIGN: Retrospective, observational study. SUBJECTS: Thirty-nine consecutive patients with acute CRVO and 12 months of follow-up. METHODS: We graded baseline SD-OCTs for increased reflectivity of the inner retina, loss of definition of inner retinal layers, presence of a prominent middle-limiting membrane (p-MLM) sign, and presence of paracentral acute middle maculopathy (PAMM)...

PurposeRanibizumab, an anti-vascular endothelial growth factor, and dexamethasone, a corticosteroid, have been shown to be effective in treating macular oedema secondary to retinal vein occlusion (RVO) (central RVO (CRVO) and branch RVO (BRVO)). Their real-world usage, however, has yet to be compared. We therefore evaluated ophthalmology visits for both drugs using US patient-level data.MethodsThe IMS Health Real-World Data Medical Claims database was used to identify treatment-naive patients receiving ranibizumab intravitreal injections or dexamethasone intravitreal implants between June 2010 and February 2014 who had 12 months of follow-up data...

Purpose: Retinal ischemia has been traditionally assessed by fluorescein angiography, visualizing perfused vessels. However, this method does not provide any information about nonperfused vessels, and although it is often assumed that vessels in ischemic areas regress, we know little about how nonperfused retinal vessels change over time. Here, we aim to learn more about the long-term fate of nonperfused vessels in the retinal vasculature. Methods: Optical coherence tomography (OCT) was used to visualize perfusion as well as structural properties of the retinal vasculature in patients suffering from retinal vascular occlusions...

A 21-year-old healthy female presented with acute-onset vision loss in the left eye. Multimodal imaging, including fundus photography and fluorescein angiography, was unremarkable. En face optical coherence tomography (OCT) demonstrated paracentral acute middle maculopathy (PAMM) lesions in a perivenular fern-like pattern leading to the diagnosis of central retinal vein occlusion (CRVO). En face OCT can be an important modality to identify the distribution of abnormalities of the middle retina such as PAMM...
