Childhood ocular safety after postnatal exposure to topical dexamethasone during retinopathy of prematurity screening

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Dexamethasone eye drops are being introduced off‐label to prevent progression of severe retinopathy of prematurity (ROP). We evaluated ophthalmologic outcomes in early childhood after postnatal topical dexamethasone exposure in pre‐term infants at a standardized follow‐up examination.

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

open access: yesClinical &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
