From basic to clinical research: a journey with the retina, the retinal pigment epithelium, the cornea, age-related macular degeneration and hereditary degenerations, as seen in the rear view mirror Nilsson SEActa Ophthalmol Scand 2006[Aug]; 84 (4): 452-65; 451PURPOSE: This Acta Ophthalmologica Award and Gold Medal Honorary Lecture (the Lundsgaard Gold Medal Honorary Lecture) reviews some of the work I have carried out with my mentors and many of my wonderful collaborators and research students over more than 40 years, also including related work by other groups. It concentrates on the basic electrophysiology and ultrastructure of the retina and the retinal pigment epithelium (RPE), as well as covering basic and clinical aspects of the cornea, contact lenses, age-related macular degeneration (AMD) and hereditary diseases. METHODS: The review describes research performed using light and electron microscopy, basic and clinical electrophysiology, genetics and biochemistry in animal experiments and in research on patients. It also outlines clinically used techniques, such as laser and photodynamic treatment and scanning laser ophthalmoscopy. RESULTS: The paper reports on the following subjects: the mechanisms behind some of the electrical potentials originating in the retina and the RPE and the use of these potentials in hereditary diseases; corneal receptors for lectins and presumably for bacteria; the turnover of the photoreceptor outer segment and the formation of lipofuscin, including the relation of these processes to AMD; certain treatments for AMD, and hereditary degenerations in animal models, such as the RPE65 gene mutation in Briard dogs, which makes them a model of Leber's congenital amaurosis. The dogs are now treated successfully with gene therapy in the USA, and a clinical trial is in preparation. CONCLUSIONS: During the last 40 years we have had the good fortune to experience a dramatic growth in knowledge and understanding within ophthalmic science of basic mechanisms. Huge progress has been made in diagnostics and clinical ophthalmological treatments, much to the benefit of our patients. Even a small contribution made by my group to these developments has been well worth the effort, particularly as scientific work is not just deeply satisfying: it is also fun!|*Awards and Prizes[MESH]|Cornea/*physiology/ultrastructure[MESH]|Electrophysiology[MESH]|Eye Diseases, Hereditary/*physiopathology/rehabilitation[MESH]|History, 20th Century[MESH]|History, 21st Century[MESH]|Macular Degeneration/*physiopathology/rehabilitation[MESH]|Ophthalmology/*history[MESH]|Pigment Epithelium of Eye/*physiology/ultrastructure[MESH]|Retina/*physiology/ultrastructure[MESH]|Societies, Medical[MESH]|Sweden[MESH] |
