Advancing Insights into Pediatric Macular Diseases: A Comprehensive Review.

Pediatric macular disorders are a diverse group of inherited retinal diseases characterized by central vision loss due to dysfunction and degeneration of the macula, the region of the retina responsible for high-acuity vision. Common disorders in this category include Stargardt disease, Best vitelliform macular dystrophy, and X-linked retinoschisis. These conditions often manifest during childhood or adolescence, with symptoms such as progressive central vision loss, photophobia, and difficulty with fine visual tasks.

In this study, we evaluated clinical outcomes following a therapy switch to Faricimab, in a patient cohort affected by neovascular age-related macular degeneration (nAMD), having received prior intravitreal anti-VEGF therapy. A retrospective investigation, including 28 eyes of 23 patients, treated for nAMD at the University Medical Center Mainz, Germany was performed. A switch in therapy to Faricimab was conducted, due to an inadequate response to the previous anti-VEGF treatment.

Sequences and three-dimensional structures of the four vertebrate arrestins are very similar, yet in sharp contrast to other subtypes, arrestin-1 demonstrates exquisite selectivity for the active phosphorylated form of its cognate receptor, rhodopsin. The N-terminus participates in receptor binding and serves as the anchor of the C-terminus, the release of which facilitates arrestin transition into a receptor-binding state. We tested the effects of substitutions of fourteen residues in the N-terminus of arrestin-1 on the binding to phosphorylated and unphosphorylated light-activated rhodopsin of wild-type protein and its enhanced mutant with C-terminal deletion that demonstrates higher binding to both functional forms of rhodopsin.

Diabetic retinopathy is characterized by hyperglycemic retinal pigment epithelial cells that secrete excessive pro-inflammatory cytokines and VEGF, leading to retinal damage and vision loss. Cobalt protoporphyrin (CoPP) is a compound that can reduce inflammatory responses by inducing high levels of HO-1. In the present study, the therapeutic effects of CoPP were examined in ARPE-19 cells under hyperglycemia.

The accurate diagnosis of central serous chorioretinopathy (CSC) and its distinction from differential diagnoses is crucial for effective patient counseling and treatment. This is achieved through a targeted patient history and multimodal imaging, which distinguish CSC from other ocular diseases also characterized by subretinal fluid and changes in the retinal pigment epithelium. In this article we identify the key differential diagnoses of CSC and illustrate the characteristic differential diagnostic features of each disease.
