Purpose: To study the effect of punctal plug placement in patients undergoing refractive surgery for correction of poor vision.
Methods: A retrospective study was performed of 12 patients (21 eyes) who presented for initial refractive surgery or retreatment after LASIK or photorefractive keratectomy to improve visual acuity. Uncorrected visual acuity (UCVA) was documented in each eye. If tear normalization test was positive (indicating dry eye), silicone punctal plugs were placed in the lower lids of both eyes. Subjective patient UCVA and Snellen UCVA were assessed at 1 month.
Results: At 1 month, two eyes improved by three Snellen lines, nine eyes improved by two lines, seven eyes improved by one line, and three eyes remained unchanged. Uncorrected visual acuity was considered statistically significant (P < .0001) using the paired t test. No eye demonstrated decrease in visual acuity. One patient experienced punctal plug extrusion in both eyes. No other adverse outcomes were reported. One patient pursued additional refractive surgery after plug placement. No patient requested plug removal.
Conclusions: Patients with low refractive errors note improvement in visual acuity after punctal plug placement.

The optimal therapeutic intervention for pediatrics with optic pathway glioma (OPG) remained controversial in the literature. Recently, due to substantial adverse events (AEs) of chemotherapy and its impact on children's lives, the efficacy of other options has been investigated. Bevacizumab (BVZ) is an anti-vascular endothelial growth factor (VEGF) agent that alters the lesion microenvironment.

Background: Choroidal neovascular membranes (CNVM) associated with optic nerve head drusen (ONHD) are rare but vision threatening. A variety of treatments, including laser photocoagulation, subretinal surgery, and anti-VEGF injections, are effective but pose risks, particularly in pediatric patients, underscoring the need for a comprehensive review.
Methods: A systematic review was conducted using PubMed, Embase, and Web of Science.

The prevailing narrative in scientific literature has long overemphasized the role of ocular axes in intraocular lens (IOL) implantation, perpetuating misconceptions that have led to unnecessary exclusions of patients. Historical assumptions, coupled with inconsistent terminology and statistical inaccuracies, have muddled clinical decision-making. This review delves into these misconceptions, offering a critical reassessment of their relevance.

Aim: To evaluate the impact of fluid volume fluctuations quantified with artificial intelligence in optical coherence tomography scans during the maintenance phase and visual outcomes at 12 and 24 months in a real-world, multicentre, national cohort of treatment-naïve neovascular age-related macular degeneration (nAMD) eyes.
Methods: Demographics, visual acuity (VA) and number of injections were collected using the Fight Retinal Blindness tool. Intraretinal fluid (IRF), subretinal fluid (SRF), pigment epithelial detachment (PED), total fluid (TF) and central subfield thickness (CST) were quantified using the RetinAI Discovery tool.
