Intraocular Pressure Measurements Using Rebound Tonometry in Eight Different Species of Companion Birds.

The purpose of this study was to determine reference interval intraocular pressure (IOP) values in 8 different species of companion birds. One hundred and nineteen companion birds (238 eyes) from a captive colony were examined: 21 pigeons (; 18%), 17 African grey parrots (; 14%), 22 common mynahs (; 18%), 24 cockatiels (; 20%), 12 zebra finches (; 10%), 9 budgerigars (; 8%), 6 domestic canaries (; 5%), and 8 ring-necked parakeets (; 7%). Intraocular pressure was measured by rebound tonometry (TonoVet) avoiding induced, undesired pressure on the head, neck, or eyes.

Effect of Topical 1% Tetracaine Hydrochloride on Intraocular Pressure in Ophthalmologically Normal Horses; a Pilot Study.

The aim of this study was to evaluate the effect of topical 1% tetracaine hydrochloride on the intraocular pressure (IOP) in ophthalmologically normal horses. Thirty eyes of 15 clinically normal horses were used for this study. The animals were randomly assigned to two groups (treatment and control).

Effects of oral administration of trimethoprim-sulfamethoxazole on tear production in clinically normal guinea pigs.

Objective: To determine the effects of short-term oral administration of trimethoprim-sulfamethoxazole on tear production in clinically normal guinea pigs.

Animal Studied: Thirty-two healthy adult Abyssinian guinea pigs were used in this study.

Procedure: One day before the start of the trial, the pretreatment baseline phenol red thread test (PRTT) values were recorded.
