Simultaneous Bilateral Primary Choroidal Melanoma Linked to Bilateral Ocular Melanocytosis: A Rare Case Study.

BACKGROUND Choroidal melanoma is the most common primary intraocular tumor in adults. Most primary choroidal melanomas are unilateral and unifocal. Bilateral primary choroidal melanomas are considered to be a rare occurrence.

Significant Preoperative Anxiety Associated with Perceived Risk and Gender in Cataract Surgery.

: Cataract surgery is an often-sought solution to the universal problem of lens opacification. Studies of perioperative anxiety have yielded conflicting results, reporting a high prevalence but low clinical significance. The objective of this study was to ascertain anxiety levels immediately after the scheduling of surgery, controlling for trait anxiety and other related factors.

Intraocular pressure, primary open-angle glaucoma and the risk of retinal vein occlusion: A Mendelian randomization mediation analysis.

Background: The etiological connection between intraocular pressure (IOP) and the risk of retinal vein occlusion (RVO) remains elusive, particularly regarding whether this risk emanates from the direct influence of elevated intraocular pressure (IOP), irrespective of the presence of primary open-angle glaucoma (POAG), or if it arises as a consequence of the sequelae of POAG. Therefore, we conducted a Mendelian Randomization (MR) mediation analysis to elucidate the mediating role of POAG in the association between IOP and RVO.

Methods: We identified 47 single-nucleotide polymorphisms (SNPs) associated with IOP (P-value < 5 × 10) leveraging data from a genome-wide association study (GWAS) (N = 97,653) obtained from the UK Biobank and 50 SNPs associated with POAG (P-value < 5 × 10) from a GWAS meta-analysis (16,677 cases and 199,580 controls).

Endothelin-1 Plasma and Aqueous Humor Levels in Different Types of Glaucoma: A Systematic Review and Meta-Analysis.

: Several studies suggest the complex relationship between Endothelin-1 (ET-1) levels with various types of glaucoma. This systematic review and meta-analysis explore ET-1 levels in plasma and aqueous humor among different types of glaucoma. : A literature search (PubMed, ScienceDirect, Cochrane Library) was made up to April 2024 (PROSPERO: CRD42023430471).
