Tear film breakup time and Schirmer tear test in normal dogs: Effects of age, sex, reproductive status, skull type, and nasolacrimal duct patency.

Objective: The present study aimed to determine the effects of age, sex, reproductive status, skull type, and nasolacrimal duct (NLD) patency on tear production and tear film breakup time (TBUT) in normal dogs.

Animals Studied: The ophthalmic data of 82 healthy adult dogs were evaluated in this study.

Procedures: Age, sex, breed, and reproductive status were recorded.

Effect of Topically Applied 0.5% Apraclonidine Versus 0.5% Timolol Maleate on Intraocular Pressure of Healthy Horses.

This study aims to assess the effect of topical 0.5% apraclonidine on Intraocular pressure (IOP) in horses and compare the effects of timolol maleate 0.5% with 0.

Effects of long-term oral administration of melatonin on tear production, intraocular pressure, and tear and serum melatonin concentrations in healthy dogs.

Objective: To evaluate the effects of long-term (30-day) oral administration of melatonin on tear production, intraocular pressure (IOP), and concentration of melatonin in the tears and serum of healthy dogs.

Animals: 20 healthy sexually intact adult male dogs.

Procedures: 10 dogs were given melatonin (0.

Comparison of conjunctival microbiota of clinically normal Persian cats with and without nasolacrimal duct obstruction.

Objective: This study was performed to determine the conjunctival microbiota of Persian cats with and without nasolacrimal duct obstruction (NLDO).

Animals Studied: Twenty-five Persian cats: 15 with bilateral NLDO (Group A) and 10 with no NLDO (Group B).

Procedures: All fifty eyes were assessed.

Effect of topical 0.5% tetracaine hydrochloride on intraocular pressure in ophthalmologically normal cats.

Objectives: The aim of this study was to assess the effect of topical tetracaine hydrochloride 0.5% on intraocular pressure (IOP) in ophthalmologically normal cats.

Methods: Twenty domestic shorthair cats (40 eyes) were used in this study.

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).

Evaluation of tear production using the Schirmer tear test I in healthy cats; effect of age, life stage, sex, breed and neuter status.

Background: The purpose of this study was to evaluate the values of Schirmer tear test (STT) and determine effects of age, life stage, sex, breed and neuter status on tear production in healthy cats.

Methods: Three hundred and forty-three domestic shorthair (DSH) and Persian cats, 50 days through 18 years old, were examined in this study. STT I was used to measure tear production in both eyes of each cat.

Effect of Topical 1% Cyclopentolate Hydrochloride on Tear Production, Intraocular Pressure, and Pupil Size in Healthy Turkman Horses.

This study was performed to evaluate the effect of topical 1% cyclopentolate hydrochloride on tear production (STT), intraocular pressure (IOP), and vertical pupil diameter (VPD) in healthy Turkman horses. Forty eyes of 20 clinically normal horses were used for this study, which were randomly assigned to two groups. Before instillation of 1% cyclopentolate, the baseline STT, IOP, and VPD of each group were recorded.

Pilot evaluation of the circadian rhythm of tear production in a population of healthy adult cats.

Objectives: The purpose of this study was to determine if a circadian rhythm exists in Schirmer's tear test (STT-1) values in a group of healthy adult cats.

Animals Studied: Twenty adult neutered Domestic Short-haired cats (DSH) were used in the study.

Procedures: Tear production was measured with the Schirmer tear test (STT-1) at 12 different time points over a 48-hour period.

Seasonal Effects on the Corneoconjunctival Microflora in a Population of Persian Cats in Iran.

This study was performed to determine the normal seasonal aerobic and an-aerobic corneoconjunctival bacterial flora in cats. Thirty eyes of 15 clinically normal client-owned Persian cats were evaluated. All cats lived in a similar indoor/outdoor home environment being fed the same diet for the entire year.
