Detection of Retinal and Choriocapillaris Microvascular Changes in Retinal Vein Occlusion and Fellow Eyes by Optical Coherence Tomography Angiography: A Systematic Review and Meta-Analysis.

Introduction: This study aims to summarize the retinal and choroidal microvascular features detected by optical coherence tomography angiography (OCTA) in the affected and fellow eyes of patients with retinal vein occlusion (RVO).
Methods: A comprehensive search of the PubMed, Embase, and Ovid databases was conducted to identify studies comparing OCTA metrics among RVO, RVO-fellow, and control eyes. Outcomes of interest included parameters related to foveal avascular zone (FAZ) and fovea- and optic nerve head (ONH)-centered perfusion measurements of superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris layer.
Evaluation of change in the contact of IOL with the posterior capsule with respect to the orientation of haptics of the IOL using intraoperative spectral domain optical coherence tomography.

Purpose: To study change in the contact of intraocular lens (IOL) with the posterior capsule with respect to the vertical versus horizontal orientation of the haptic-optic junction of the IOL using intraoperative spectral domain optical coherence tomography (SD-OCT).
Methods: Fifty eyes of 50 patients with senile immature cataract underwent topical phacoemulsification procedure with implantation of a monofocal IOL by a single experienced surgeon. The Rescan 700 SD-OCT system was used for intraoperative imaging.
Transconjunctival Orbital Decompression in Cherubism.

Department of Ophthalmology, School of Medicine of Ribeirão Preto, University of São Paulo.
Cherubism is a rare fibro-osseous disease characterized by the progressive expansion of the mandible and maxilla during childhood. Orbital involvement occurs in a subset of patients and is clinically manifested as upward displacement of the affected eye. The bony changes tend to spontaneously diminish or even regress after puberty.

The use of optogenetic tools offers an excellent method for spatially and temporally regulated gene and protein expression in cell therapeutic approaches. This could be useful as a concomitant therapeutic measure, especially in small body compartments such as the inner ear, for example, during cochlea implantation, to enhance neuronal cell survival and function. Here, we used the blue light activatable CRY2/CIB system to induce transcription of brain-derived neurotrophic factor (BDNF) in human cells.

Polymethacrylate and its derivatives are widely used in food industry and biomedical applications for their plasticity, biocompatibility and optical transparency. However, susceptibility to bacterial growth on their surfaces limits their applications. In this study, linear and branched polyethyleneimine (PEI) molecules were grafted onto poly(ethyl methacrylate) (PEMA) via aminolysis using a simple one-step method to enhance the antibacterial properties of PEMA films.
