Bilateral, anterior stromal ring opacity of the cornea

AIMS/BACKGROUND: To describe a bilateral, mid peripheral, ring-shaped corneal opacity, not resembling any known corneal degeneration, dystrophy, or other disorder, and occurring without ocular or systemic disease. METHODS: Ophthalmic examination, haematological screening, and ultrasound biomicroscopy. RESULTS: A 25 year old man showed grey-white, granular opacities in both corneas, with an 8 mm diameter ring configuration, and a V-shaped distribution in the anterior stroma. The surrounding corneal stroma was clear, and the tear film, the epithelium and its basement membrane, Descemet's membrane, and the endothelium were normal. Evidence of systemic disease was not found. Family members did not show corneal abnormalities. CONCLUSION: A bilateral corneal ring opacity may occur in healthy, asymptomatic, young people. These corneal rings may result from depositions of unknown origin, or possibly a rare corneal dystrophy

Increase in treatment of retinopathy of prematurity in the Netherlands from 2010 to 2017

Purpose: Compare patients treated for Retinopathy of Prematurity (ROP) in two consecutive periods. Methods: Retrospective inventory of anonymized neonatal and ophthalmological data of all patients treated for ROP from 2010 to 2017 in the Netherlands, subdivided in period (P)1: 1-1-2010 to 31-3-2013 and P2: 1-4-2013 to 31-12-2016. Treatment characteristics, adherence to early treatment for ROP (ETROP) criteria, outco

Postoperative management and follow-up after corneal flap loss following laser in situ keratomileusis.

Item does not contain fulltextWe present 3 cases of flap loss within 2 weeks of unilateral laser in situ keratomileusis. In all patients, spontaneous regeneration of the epithelial layer, covering the ablated stroma, was expected. In 2 patients, the best spectacle-corrected visual acuity recovered to 20/25 within 6 months and in 1 patient, a contact lens was fitted 6 months after the accident, restoring visual acuity to 20/25. The 6-month follow-up and the contact lens fitting technique are described
