6. Diagnosing and monitoring open-angle glaucoma. Pupillometry and other novel techniques
Sammanfattning : Aim:To investigate the ability of a custom-built pupillometer and other novel diagnostic instruments to detect and monitor optic nerve damage in glaucoma.Methods:In the first two studies we investigated pupillary reactions to light in patients with glaucoma and in healthy persons using a custom-built pupillometer.

7. Improved computerized perimetric threshold strategies
Sammanfattning : Perimetric threshold examination is the most important method for diagnosing and monitoring patients with glaucoma. Such examination, however, is time-consuming and often difficult for the elderly patients in whom glaucoma is prevalent. Shorter test strategies have been proposed, but unfortunately also with lower test quality. LÄS MER
8. Investigations or perimetry and gaze-stability in healthy and deceased retina
Sammanfattning : Our visual world is composed of images of colours, textures, edges and contrasts. In addition, these images may be moving or flickering. The goal of visual testing is to quantify these functions. LÄS MER
9. The Rarebit fovea test : a new measure of visual function
Sammanfattning : Visual acuity (VA) measurement by the use of letter charts is the most frequently used method for testing foveal function. However, since a decimal visual acuity of 1. LÄS MER
10. Machine Learning Algorithms for Improved Glaucoma Diagnosis
Sammanfattning : Primary open angle glaucoma, one of the leading causes of blindness in the world, constitutes a slow progressing condition characterized by damage to the optic nerve and retinal nerve fibre layer, and results in visual field defects afflicting the visual function. Highly specific and sensitive diagnostic tests able to detect the clinically significant glaucomatous changes in the structure of the nerve fiber layer and visual field are therefore required for the early detection and management of this disease.
