2. 1. On the necessity of screening and national registration of congenital cataracts

   Author : Gunilla Magnusson; Göteborgs universitet; []
   Keywords : congenital cataract; glaucoma; intraocular surgery; posterior capsular opacification PCO ; prevalence; visual acuity VA ; visual impairment; screening; newborn examination; blindness prevention; cost-utility analysis; quality- adjusted life year QALY ;

   Abstract : Objectives: The overall aim of this thesis was to contribute to improvements in the management of congenital cataract by defining the most efficient screening procedure, examining the magnitude of the morbidity rate, optimizing the timing of surgery by relating surgical outcome to age at intervention and severity of visual deprivation and furthermore by evaluating costs versus consequences of introducing the most efficient screening procedure found, on a national basis.Methods: Paper I: 72 children born between 1992 and 1998 in the Stockholm County Council region, Västra Götaland and Halland county, Linköping-Motala, Malmö, and Lund, who had surgery for congenital cataract before the age of one year were included in a retrospective study.

4. 2. Usher syndrome. Prevalence and phenotype - genotype correlations

   Author : Mehdi Sadeghi; Göteborgs universitet; []
   Keywords : deafblindness; Usher syndrome; retinitis pigmentosa; prevalence; Usher type I; Usher type II; Usher type III; vestibular deficiency; hereditary hearing loss;

   Abstract : Aims: the main purpose of this thesis was to estimate the prevalence of Usher syndrome type I, II and III in Sweden (study I) and to determine the clinical differences between Usher syndrome subtypes (studies II-IV). The hypothesis to be tested was that different genes for Usher syndrome will produce different phenotypes even when they belong to the same clinical type (studies II and III). READ MORE

5. 3. Fuchs’ endothelial corneal dystrophy : Genetic aetiology and as a risk factor in cataract surgery

   Author : Andreas Viberg; Berit Byström; Irina Golovleva; Patrik Danielson; Madeleine Zetterberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fuchs’ endothelial corneal dystrophy; genetics; TCF4; trinucleotide repeat disorder; registry-based study; cataract surgery; outcome; PROM; corneal transplantation; dense cataract; posterior capsule rupture; oftalmiatrik; ophthalmology; Clinical Genetics; klinisk genetik;

   Abstract : Fuchs’ endothelial corneal dystrophy (FECD) is a bilateral, often hereditary degenerative corneal disease, in which the disrupted endothelial cell function causes corneal swelling and reduced vision. An early clinical sign of FECD is corneal guttata, an irregularity of the endothelial layer. READ MORE

6. 4. Studying prevalence using capture-recapture methods : visual impairment in Portugal

   Author : Pedro Lima Ramos; António Filipe Macedo; Ines Sousa; Amândio Rocha Sousa; Linnéuniversitetet; []

7. 5. Hyperglycaemia and diabetic eye complications - a clinical and epidemiological study

   Author : Marianne Henricsson; Oftalmologi (Malmö); []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mortality; blindness; cataract surgery; oral antihyperglycaemic agents; hyperglycaemia; insulin treatment; non-insulin dependent diabetes mellitus; diabetic retinopathy; insulin-dependent diabetes mellitus; Ophtalmology; Oftalmologi;

   Abstract : Aim: To study the relationship between hyperglycaemia and the onset/progression of retinopathy, blindness/moderate visual impairment or death, as well as the impact of improved glycaemic control on retinopathy in patients with non-insulin-dependent diabetes mellitus (NIDDM). Methods: Between January 1990 and October 1995 a total of 3,220 diabetic patients were enrolled in a programme for control and screening for retinopathy. READ MORE
