Artificial intelligence prediction algorithms for refractive error onset and progression in children and adolescents: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract This systematic review and meta‐analysis evaluates the performance of artificial intelligence (AI)‐based models for predicting the onset and progression of refractive error (RE) in children and adolescents and quantitatively synthesizes their prediction accuracy.

Biopsy of Iris and Anterior Chamber Tumours: Fine Needle, Minimally Invasive and Excision Techniques ‐ Review

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Several benign, inflammatory and malignant lesions can present as iris or anterior chamber masses, including iris naevi, cysts, adenomas, leiomyomas, nodules, vascular tumours, melanomas, metastases, as well as iris and pigment epithelium adenocarcinomas. Fortunately, benign iris lesions are much more common than malignant tumours and many can

Prevalence and Pattern of Refractive Errors Among Yanomami Indigenous People in the Brazilian Amazon: A Cross‐Sectional Observational Study

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Refractive errors are the leading cause of preventable visual impairment worldwide, yet data from isolated Indigenous populations remain virtually absent from the global literature. The Yanomami, one of the largest Indigenous peoples in the Americas with recent and limited contact with non‐Indigenous society, have no prior ...
