1. Optics for Low Vision Enabling
Sammanfattning : For people with central visual field loss, eccentric vision is all that they have to rely on. Even for those who learn how to correctly utilize their eccentric vision, it will never be as good as the central for two entirely different reasons: the off-axis optics of the eye can result in large refractive errors, and the low function of the peripheral retina.

2. Optimal Use of Peripheral Vision
Sammanfattning : People who lose their central vision have to rely on their peripheral vision for all visual tasks. The ability to resolve fine details in the periphery is reduced due to retinal limitations and the optical aberrations arising from the use of off-axis vision. LÄS MER
3. Improving Peripheral Vision Through Optical Correction and Stimulus Motion
Sammanfattning : The loss of central vision subsequent to macular disease is often extremely debilitating. People with central field loss (CFL) must use other peripheral areas of the retina in order to see; areas with inferior resolution capacity, which are also affected by off-axis optical errors.

4. 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
5. Age-related maculopathy and macular degeneration : New diagnostic and therapeutic procedures
Sammanfattning : Age-related maculopathy (ARM) may progress into age-related macular degeneration (AMD), which is often disastrous to near vision and reading. Currently used treatment is generally not successful in a long-term perspective. Therefore, searching for an early detection of functional disturbances as well as for prophylactic treatment appears important. LÄS MER
