Glaucoma detection

Research Description

Glaucoma is mostly an asymptomatic blinding disease. An early and accurate diagnosis is desirable to reduce morbidity.

We are developing new imaging devices and scanning techniques to improve diagnosis. We are testing new devices to explore their diagnostic ability.

We are developing new diagnostic parameters and exploring new methods of combining information from various scanning regions. We are working on new ocular imaging devices. We are exploring combinations of structure and functional information.

We are working towards identifying confounders that might affect structure dependent diagnosis such as scan location and image quality.

Devices used to detect glaucoma

  1. Visual field pattern deviation map shows inferior functional damage. 

  2. Scanning laser polarimetry imaging indicates a thin retinal nerve fiber layer (RNFL) in the superotemporal region, which corresponds to the visual field damage.

  3. Imaging with confocal scanning laser ophthalmoscope indicates superior abnormalities.

  4. Spectral domain optical coherence tomography deviation map indicates abnormalities both superiorly and inferiorly.

  5. The cross section image from time domain optical coherence tomography shows a thin RNFL in the circumpapillary region.
