myopia treatment

BACKGROUND: Rhegmatogenous retinal detachment (RRD) is a serious condition that occurs when the retina detaches from its underlying retinal pigment epithelium. RRDs associated with giant retinal tears (GRTs) are caused by retinal tears at least 90° or one-quarter of the circumferential extent. This scoping review systematically identifies and summarizes clinical studies evaluating surgical techniques for the management of GRT-related RRDs, discusses functional and visual outcomes and the risk factors affecting treatment outcomes...

We report the case of a 32-year-old male who presented with an acute myopic shift as a result of uveal effusion following a single administration of 250 mg acetazolamide. The drug was discontinued and following cycloplegia and topical steroid therapy, we observed progressive deepening of the anterior chamber, reopening of the iridocorneal angle, and complete resolution of the myopic shift after 5 days. A literature review since 1956 identified 23 cases, including ours, which developed a myopic shift after a median time of 24 h (3 - 24) following a median dose of 500 mg (125 - 1000) acetazolamide, with about a third complicated by angle closure ocular hypertension...

A review of the literature completes our observation...

Myopia, the most prevalent eye condition, has sparked notable interest regarding its origin and prevention. MicroRNAs (miRNAs) are short, non-coding RNA strands typically consisting of 18-24 nucleotides. They play a central role in post-transcriptional gene regulation and are closely associated with both normal and pathological processes in organisms. Recent advances in next-generation sequencing and bioinformatics have provided novel insights into miRNA expression and its regulatory role in myopia. This review discusses the distinct expression patterns, regulatory functions, and potential pathways of miRNAs involved in the onset and progression of myopia...
