BACKGROUND/AIMS: Patients with rhegmatogenous retinal detachment (RRD) who develop postoperative proliferative vitreoretinopathy (PVR) have been found to have higher preoperative laser flare values than patients with RRD who do not develop this complication. Measurement of laser flare has therefore been proposed as an objective, rapid and non-invasive method for identifying high-risk patients. The purpose of our study was to validate the use of preoperative flare values as a predictor of PVR risk in two additional patient cohorts, and to confirm the sensitivity and specificity of this method for identifying high-risk patients...

We describe an electrochemical method of harvesting cells cultured on a biodegradable polymeric nanosheet (cell/nanosheet construct), which is stabilized on a self-assembled monolayer (SAM) of thiol molecules. A poly(lactic-co-glycolic acid) (PLGA) nanosheet was attached by hydrophobic interactions onto the surface of a SAM of l-cysteine coated onto a gold electrode. Retinal pigment epithelial cell lines (RPE-J cells) were cultured on the nanosheet to form a monolayer. An AA-size dry battery was used to apply a negative electrical potential, causing reductive desorption of the SAM from the gold surface...

A 12-year-old boy presented with a total rhegmatogenous retinal detachment and a giant retinal tear in the right eye. Clinical examination, optical coherence tomography, and fundus images showed an optically empty vitreous, lattice degeneration, and retinoschisis of the macula. Genetic testing revealed mutations in the COL2A1 and RS1 genes, confirming a dual diagnosis of Stickler syndrome and X-linked retinoschisis, respectively. This represents the first published account of a patient with both Stickler syndrome and X-linked retinoschisis...

Subretinal injections have been successfully used in both humans and rodents to deliver therapeutic interventions of proteins, viral agents, and cells to the interphotoreceptor/subretinal compartment that has direct exposure to photoreceptors and the retinal pigment epithelium (RPE). Subretinal injections of plasminogen as well as recent preclinical and clinical trials have demonstrated safety and/or efficacy of delivering viral vectors and stem cells to individuals with advanced retinal disease. Mouse models of retinal disease, particularly hereditary retinal dystrophies, are essential for testing these therapies...

AIM: Perfluorocarbon liquid (PFCL) can migrate into subretinal space in detached and stiffened retina with open holes during vitreoretinal surgery. An innovative 'soft shell' technique was introduced to reduce the complication using hyaluronate (HA) to 'cover' the retinal hole. This study aims to study the effectiveness of this technique in vitro. METHODS: Ex vivo porcine retina was mounted on a transwell insert. Beneath the retina was an aqueous solution. Two retinal holes were made using needle punctures...
