Retinal vessel diameters of 45 diabetic children and adolescents with diabetes were measured on black-and-white fundus photographs (negatives) using digital image analyses technique and microdensitometry as well as with direct micrometry. The changes in vessel diameters in two sets of photographs taken at an interval of 2.4 +/- 0.3 years were compared with(More)
PURPOSE AND METHODS Adolescent patients with insulin-dependent diabetes mellitus (IDDM) were retrospectively analyzed for the occurrence and possible predisposing factors of diabetic cataract in a population-based series of some 600 pediatric diabetics followed up during the years 1975-1995. RESULTS Six patients (1%) needed cataract surgery. At the(More)
Amiodarone is a commonly prescribed and one of the most effective anti-arrhythmic drugs available. However, its use is limited by serious toxic adverse effects including optic neuropathy. Previously, amiodarone-associated optic neuropathy has been reported at an incidence of 1.3%-1.8%. Nearly, one-third of patients with amiodarone-induced toxic optic(More)
PURPOSE It is necessary to develop tools for patient selection to target cataract surgery to patients with the best expected outcomes. We used visual acuity, visual functioning 14 (VF-14) test, the 15-dimension health-related quality-of-life questionnaire (15D) and the New Zealand priority criteria to evaluate the criteria for cataract surgery in a post hoc(More)
PURPOSE The Pyhäjärvi Cataract Study aims to study demand for cataract surgery in the population of a rural town in Finland. METHODS A random, population-based sample of 881 persons aged > or = 60 years were interviewed by telephone to obtain a Visual Function-14 (VF-14) score. A total of 294 persons were invited for an ophthalmic examination based on(More)
The prevalence of retinopathy in children with insulin-dependent diabetes mellitus (IDDM) was studied in a population-based survey on 194 of the 216 subjects (89.8%) with IDDM aged 4.6 to 16.6 years living in the county of Oulu, Finland. The diagnosis of retinopathy was based on fundus photography. The median age of the children was 12.2 years and the(More)
AIM A population-based study was carried out to evaluate the prevalence and risk factors of diabetic retinopathy (DR) in children with type 1 diabetes (T1D) in The Northern Osthrobothnia Hospital District, Finland. The aim was to compare the current prevalence and the risk factors with those obtained in a study performed in a similar setting 17 years(More)
AIM To determine the sensitivity and specificity of the stereometric optic nerve head (ONH) parameters of the Heidelberg Retina Tomograph (HRT) to detect an event of progression verified in serial stereoscopic ONH photography. METHODS A retrospective study of 476 eyes of 342 patients with more than 18 months of follow-up with successful stereoscopic ONH(More)
PURPOSE The purpose of this study was to retrospectively evaluate whether it is possible to decrease the risk of Molteno tube erosion through the conjunctiva by using a new technique where the silicone tube is inserted into a scleral tunnel instead of being covered only by the conjunctiva. METHODS We reviewed Molteno implants carried out at the University(More)
