Introduction: Traditional extraocular electrical stimulation typically produces diffuse electric fields across the retina, limiting the precision of targeted therapy. Temporally interfering (TI) electrical stimulation, an emerging approach, can generate convergent electric fields, providing advantages for targeted treatment of various eye conditions.
Objective: Understanding how detailed structures of the retina, especially the optic nerve, affects electric fields can enhance the application of TI approach in retinal neurodegenerative and vascular diseases, an essential aspect that has been frequently neglected in previous researches.

Objective The objective of this study is to compare patient-reported outcome measures using the Catquest Questionnaire in patients undergoing phacoemulsification (Phaco) versus manual small-incision cataract surgery (MSICS). Materials and methods This descriptive cross-sectional study included patients aged 40 years and older with cataracts classified as nuclear sclerosis (NS) grade 3 or higher. Demographic details were recorded and a comprehensive ophthalmological exam was done.

A post hoc analysis of the OAKS phase III trial was conducted, which enrolled patients with GA secondary to age-related macular degeneration. Microperimetry using a standard 10-2 fovea centered grid was performed at baseline and follow-up visits.

Intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) medications are the primary treatment for neovascular age-related macular degeneration (nAMD). However, frequent administrations pose significant burdens on patients, healthcare providers, and systems. The treat-and-extend (T&E) regimen, which adjusts treatment intervals based on patient response, aims to reduce injection frequency while maintaining disease control.

Introduction: Phosphoribosyl pyrophosphate synthetase 1 () is an X-linked gene critical for nucleotide metabolism. Pathogenic variants cause three overlapping phenotypes: Arts syndrome (severe neurological disease), Charcot-Marie-Tooth type 5 [CMTX5] (peripheral neuropathy), and non-syndromic sensorineural hearing loss (SNHL). Each may be associated with retinal dystrophy.
