Technique
Gonioscopy can be accomplished using one of two methods.
Method 1: Place the gonioscope on the eye with mirrors arranged perpendicular and planar to horizon.

- Observation is begun in the inferior angle using the superior mirror.
- Next, lower the slit lamp beam to the inferior mirror to check the superior angle.
- Finally, with the beam horizontal and tilted, observe the angle near the 180° meridian.
Method 2: Place the gonioscope on the eye with the mirrors arranged obliquely (diamond position). In this orientation, nearly all of the angle can be observed.
With the slit lamp beam vertical, simply move the slit lamp from right to left across the two superior mirrors.
Next, lower the beam and move the slit beam from left to right across the two inferior mirrors. Complete observation of the angle can be quickly achieved with minimal rotation of the lens (11° in either direction) is needed to view the small sections of angle, which were missed during the initial sweep.
Because of the light weight and small size of this gonio lens, it is easily applied to the eyes of small children and individuals with narrow palpebral fissures.
