  • Abstract
  • Look Inside

An analysis of optical features of Koeppe-and Goldmann-type was carried out as a preli-minary step to the construction of an improved setup for biomicrogoniophotography.

1. Spot-diagram analysis of Koeppe- and Gold-mann-type goniolenses, when combined with the Gullstrand model eye, has shown that certain aberrations do exist. The estimated aberrations were of similar order for both types and were independent of the angle of the incident ray.

2. 4.8% of the incident ray was lost before reaching the chamber angle and was converted into flare or ghost of the gonioscopic image.
