The present research intends to propose a fully automatic algorithm for the classification of three-dimensional (3-D) optical coherence tomography (OCT) scans of patients suffering from abnormal macula from normal candidates. The method proposed does not require any denoising, segmentation, retinal alignment processes to assess the intraretinal layers, as well as abnormalities or lesion structures. To classify abnormal cases from the control group, a two-stage scheme was utilized, which consists of automatic subsystems for adaptive feature learning and diagnostic scoring...

Increasing evidence has demonstrated that excessive blue-light (BL) with high photochemical energy and phototoxicity could induce apoptosis in retinal pigment epithelium (RPE) cells. RPE apoptosis leads to retina damage and further aggravate age-related macular degeneration (ARMD). Because of their neuroprotective, plasticity, and immunomodulatory ability, bone marrow mesenchymal stem cells (BMSCs) are recognized for retinal neuroprotection. RPE cells possess ciliary neurotrophic factor (CNTF) receptor complexes and can respond to CNTF; hence, we investigated the effects of BMSCs over-expressing CNTF on BL-injured RPE cells...

Large traumatic macular holes (TMHs) tend to be irregular and have a variable predictability. The inverted flap technique makes use of remnants of internal limiting membrane (ILM) at the periphery of the MH. The peeled-off ILM contains Müller cell fragments which can induce gliosis and help in closure of MH. We operated on a case of large TMH (~899 μ minimum linear diameter) with choroidal rupture and subretinal hemorrhage in a young female with the inverted flap technique of ILM peeling and observed successful closure of the MH...

Aptamer-related technologies represent a revolutionary advancement in the capacity to rapidly develop new classes of targeting ligands. Structurally distinct RNA and DNA oligonucleotides, aptamers mimic small, protein-binding molecules and exhibit high binding affinity and selectivity. Although their molecular weight is relatively small-approximately one-tenth that of monoclonal antibodies-their complex tertiary folded structures create sufficient recognition surface area for tight interaction with target molecules...

SIGNIFICANCE: Age-related macular degeneration (AMD) is a leading cause of irreversible vision loss. Complementary imaging techniques can be used to better characterize and quantify pathological changes associated with AMD. By assessing specific light-tissue interactions, polarization-sensitive imaging can be used to detect tissue disruption early in the disease process. PURPOSE: The aim of this study was to compare variability in central macular polarization properties in patients with nonexudative AMD and age-matched control subjects...

Protein deglycase DJ-1 (Parkinson disease protein 7) is a 20 kDa protein encoded by PARK7 gene. It is also known as a redox-sensitive chaperone and sensor that protect cells against oxidative stress-induced cell death in many human diseases. Though increasing evidence implicates that DJ-1 may also participate in ocular diseases, the overview of DJ-1 in ocular diseases remains elusive. In this review, we discuss the role as well as the underlying molecular mechanisms of DJ-1 in ocular diseases, including Fuchs endothelial corneal dystrophy (FECD), age-related macular degeneration (AMD), cataracts, and ocular neurodegenerative diseases, highlighting that DJ-1 may serve as a very striking therapeutic target for ocular diseases...
