RESUMO
Gonioscopy is an important component of evaluation of any glaucoma patient. Goldmann two-mirror and Sussman or Zeiss four-mirror are the commonly used gonioscopes. Presence of synechia in the angle is diagnostic of angle closure disease in an occludable angle. A patient with pseudo-goniosynechia that disappeared on indentation gonioscopy with Sussman lens but persisted with manipulation gonioscopy with a Goldmann lens is reported.

Precautions to prevent spread of infection through tonometers and gonioscopes are described in this article. Tonometers and gonioscopes should not be used in the presence of clinically manifest conjunctivitis and keratitis. The Schiotz tonometer should be dipped in a 1:1000 merthiolate solution, and rinsed in saline/distilled water prior to use. The Goldmann applanation prism tip can be wiped with gauze soaked in 70% isopropyl alcohol and then dried before use. Gonioscopes should be cleaned in running water, wiped with gauze soaked in 70% isopropyl alcohol, and then dried before use. Koeppes and goniotomy lenses can be sterilized with ethylene oxide, prior to use in surgery.
