Visual Field Defect Estimation Using Sequentially Optimized Reconstruction Strategy on Healthy and Glaucoma Subjects

Glaucoma, Open-Angle Clinical Trial

Official title:
Non-inferiority Study for Visual Field Mean Defect Estimation Using Sequentially Optimized Reconstruction Strategy (SORS) With an OCTOPUS 900 Perimeter on Healthy and Glaucoma Subjects

Clinical Trial Summary

Perimetry is a well-established method that is used to measure the visual field functions of humans. Commercially available products, such as the OCTOPUS 900 (Haag-Streit AG, Koeniz, Switzerland), are commonly used for assessing the visual field. Such devices are of critical value for patients suffering of glaucoma and neuro-ophthalmic conditions. The operating principle is to sequentially present light stimuli of different intensity at different locations within the visual field in an automatic way. Algorithms that select what locations and intensities to present over time are called strategies. These have the goal to provide both a fast and accurate estimation of the visual field function.

Recently, new strategies were developed that are faster and equally accurate as the strategies used today. The technological advancement of these new methods lies primarily in the ability to estimate location sensitivities without observing them directly but by leveraging previously queried locations. For this the investigators plan to implement the next generation of perimetry strategies into an OCTOPUS 900 and to test it in healthy subjects and glaucoma patients.
