1. Retinal Transplants: Growth Differentiation Integration Organization and Survival
Abstract : The goal of the study was to get a better understanding of factors controlling the growth, differen-tia-tion, integration, organization and survival of retinal transplants, with the long-term view of eventually developing retinal transplantation into a clinically useful procedure for treating degenerative retinal disorders such as retinitis pigmentosa. Embryonic day 15 rabbit retinas were transplanted into adult rabbit eyes and were allowed to survive for various times. READ MORE

2. rd1 Photoreceptor Degeneration: Photoreceptor Rescue and Role of Metalloproteases in Retinal Degeneration
Abstract : The thesis is focused on an attempt to delay photoreceptor cell death in the rd1 mouse using Lens Epithelium Derived Growth Factor (LEDGF), Glutathione S-Transferase mu (GST-?? and Glutathione S-Transferase alpha (GST-?? in an organ culture paradigm as well as the role of metalloproteases (MMPs) and their tissue inhibitors in photoreceptor degeneration (TIMPs). The rd1 mouse model displays a retina degeneration which starts around day 10 with rod photoreceptor cell death. READ MORE

3. Genes and proteins controlled by cGMP-PKG during retinal degeneration
Abstract : prevalence was reported as 1:3000-4000 worldwide, making it the main reason for blindness in the working population in industrial countries. The mutations of over 70 genes have been related to this genetic disorder, and there is generally no effective treatment, except for gene therapy for the RPE65 mutations. READ MORE

4. Retinal function in deaf-blind syndromes
Abstract : A variety of disorders can cause retinal degeneration and hearing impairment, and it is of great value to have an early diagnosis since there is a large variation in phenotype and prognosis both within and between the different disorders. The general aim of this thesis was to characterize the retinal function, to describe the phenotype, and – where appropriate – to relate the phenotype to genotype in patients with combined visual and hearing impairment.

5. The potential role of retinal cGMP-interaction partners within the degeneration mechanism causing Retinitis Pigmentosa
Abstract : The eye disease Retinitis Pigmentosa (RP) represents a heterogeneous group of inherited retinal dystrophies, and it has been estimated that 1 in 3000 to 7000 people worldwide has the disease. The symptoms of RP are photoreceptor degeneration that leads to night blindness, followed by a decline in peripheral and central vision, and potential blindness. READ MORE
