Optical coherence tomography (OCT) has become an established diagnostic technology in the clinical management of age-related macular degeneration (AMD). OCT is being used for primary diagnosis, evaluation of therapeutic efficacy, and long-term monitoring. Computer-based advances in image analysis provide complementary imaging tools such as OCT angiography, further novel automated analysis methods as well as feature detection and prediction of prognosis in disease and therapy by machine learning. In early AMD, pathognomonic features such as drusen, pseudodrusen, and abnormalities of the retinal pigment epithelium (RPE) can be imaged in a qualitative and quantitative way to identify early signs of disease activity and define the risk of progression...

In a number of cases of retinal detachment, treatment may require the removal of the vitreous humour within the eye and replacement with silicone oil to aid healing of the retina. The insertion of silicone oil offers the opportunity to also deliver drugs to the inside of the eye; however, drug solubility in silicone oil is poor and release from this hydrophobic drug reservoir is not readily controlled. Here, we have designed a range of statistical graft copolymers that incorporate dimethylsiloxane and ethylene glycol repeat units within the side chains, allowing short chains of oligo(ethylene glycol) to be solubilised within silicone oil and provide hydrogen bond acceptor sites to interact with acid functional drug molecules...

We report a case of a choroidal neovascular membrane (CNVM) associated with sclerochoroidal calcification (SCC). An asymptomatic, 72-year-old male was referred to our institution for yellow-white placoid retinal lesions of both eyes. B-scan ultrasonography confirmed the diagnosis of SCC, and indocyanine green angiography confirmed the presence of an associated CNVM. Due to enlargement of a hemorrhagic pigment epithelial detachment associated with the CNVM over the course of 7 months, the patient was treated with a series of bevacizumab injections followed by photodynamic therapy (PDT)...

Retinal fibrosis, characterized by dysregulation of extracellular matrix (ECM) protein deposition by retinal endothelial cells, pigment epithelial cells, and other resident cell-types, is a unifying feature of several common retinal diseases. Fibronectin is an early constituent of newly deposited ECM and serves as a template for assembly of other ECM proteins, including collagens. Under physiologic conditions, fibronectin is found in all layers of Bruch's membrane. Proliferative vitreoretinopathy (PVR), a complication of retinal surgery, is characterized by ECM accumulation...
