Assessment of intraocular pressure in chinchillas of different age groups using rebound tonometry Ciência Rural
Chacaltana,Flor Diana Yokoay Claros; Pigatto,João Antonio Tadeu; Denardin,Ione Terezinha.
ABSTRACT: The aim of this research was to measure the intraocular pressure (IOP) of normal chinchilla eyes using the rebound tonometer. A further aim was to assess whether there were differences in the values of intraocular pressure in relation to animals age, gender and time of day. Thirty-six chinchillas were divided into three groups of 12 chinchillas each, by age: Group I (2-6-month-old), Group II (20 and 34 months) and Group III (37 and 135 months). Ophthalmic examination was performed previously by Schirmer tear test, slit lamp biomicroscopy, indirect ophthalmoscopy and fluorescein test in all chinchillas. Three measurements of intraocular pressure were assessed on the same day (7, 12 and 19h). Tonometry was performed on both eyes using the rebound...

Avian ophthalmic peculiarities Ciência Rural
Carvalho,Clarissa Machado de; Rodarte-Almeida,Ana Carolina da Veiga; Santana,Marcelo Ismar Silva; Galera,Paula Diniz.
ABSTRACT: Morphology and physiology of bird eyes are similar to mammals; although, there are peculiarities that should be considered for a correct interpretation of an ophthalmic examination. While the ophthalmology of domestic species is already well established, there are gaps to be filled regarding birds, particularly due to the large number of existing species. This literature review consists of a brief contribution regarding peculiarities of anatomy, physiology, and ophthalmic semiotechnique of the avian eye.

Effects of submaximal exercise with water ingestion on intraocular pressure in healthy human males BJMBR
Moura,M.A.; Rodrigues,L.O.C.; Waisberg,Y.; de Almeida,H.G.; Silami-Garcia,E..
The effects of exercise and water replacement on intraocular pressure (IOP) have not been well established. Furthermore, it is not known whether the temperature of the fluid ingested influences the IOP response. In the present study we determined the effect of water ingestion at three temperatures (10, 24 and 38ºC; 600 ml 15 min before and 240 ml 15, 30 and 45 min after the beginning of each experimental session) on the IOP of six healthy male volunteers (age = 24.0 ± 3.5 years, weight = 67.0 ± 4.8 kg, peak oxygen uptake (VO2peak) = 47.8 ± 9.1 ml kg-1 min-1). The subjects exercised until exhaustion on a cycle ergometer at a 60% VO2peak in a thermoneutral environment. IOP was measured before and after exercise and during recovery (15, 30 and 45 min) using...

ABSTRACT The aim of this study was to evaluate changes in intraocular pressure (IOP), pupil size (PS), blood pressure (BP), heart rate (HR), and ECG variables (Pms wave PmV, PR interval, QRS complex, RMV wave and QT intervals) over time during the instillation of 0.5% timolol, 0.5% levobunolol and 0.5% apraclonidine in clinically normal dogs. Ten adult beagles were used. Baseline values were measured at 8a.m., 2p.m. and 8p.m., for three consecutive days. A waiting period of 10 days between the administrations of each drug was established. For 15 consecutive days, the drug being tested was instilled in one eye of each dog twice a day (7a.m. and 7p.m.). The parameters were evaluated at the aforementioned times on days 3, 6, 9, 12 and 15. Data were...

Exercise training prevents increased intraocular pressure and sympathetic vascular modulation in an experimental model of metabolic syndrome BJMBR
Castro,E.F.S.; Mostarda,C.T.; Rodrigues,B.; Moraes-Silva,I.C.; Feriani,D.J.; De Angelis,K.; Irigoyen,M.C..
The present study aimed to study the effects of exercise training (ET) performed by rats on a 10-week high-fructose diet on metabolic, hemodynamic, and autonomic changes, as well as intraocular pressure (IOP). Male Wistar rats receiving fructose overload in drinking water (100 g/L) were concomitantly trained on a treadmill for 10 weeks (FT group) or kept sedentary (F group), and a control group (C) was kept in normal laboratory conditions. The metabolic evaluation comprised the Lee index, glycemia, and insulin tolerance test (KITT). Arterial pressure (AP) was measured directly, and systolic AP variability was performed to determine peripheral autonomic modulation. ET attenuated impaired metabolic parameters, AP, IOP, and ocular perfusion pressure (OPP)...

Intraocular pressure and its correlation with blood gas parameters in crested caracaras (Caracara plancus) anesthetized with isoflurane and sevoflurane Arq. Bras. Med. Vet. Zootec.
Ribeiro,A.P.; Vitaliano,S.N.; Thiesen,R.; Escobar,A.; Duque Ortiz,J.P.; Belmonte,E.A.; Werther,K.; Laus,J.L..
The intraocular pressure (IOP) and its correlations with arterial carbon dioxide partial pressure (PaCO2) and arterial pH were studied in five crested caracaras (Caracara plancus) anesthetized with isoflurane (ISO) and sevoflurane (SEV). Baseline IOP values were measured in both eyes (M0). Brachial artery was previously catheterized to obtain blood gas and cardiorespiratory analysis. Anesthesia was induced with 5% ISO and maintained with 2.5% for 40 minutes. IOP measurements and blood samples were evaluated in different moments until the end of the procedure. After recovering, a second anesthesia was induced with 6% SEV and maintained with 3.5%. Parameters were evaluated at the same time points of the previous procedure. IOP reduced significantly (P=...

Lip twitch restraint on rebound tonometry in horses Ciência Rural
Andrade,Maria Cristina Caldart de; Hünning,Paula Stieven; Pereira,Fabiana Quartiero; Dutra,Kadigia Pitol; Pigatto,João Antonio Tadeu.
ABSTRACT: The purpose of this study was to verify the effect of the upper lip twitch restraint on intraocular pressure (IOP) of healthy horses. In this study, forty five Criollo horses, aged between two to 20 years (male or female) were evaluated with rebound tonometer, with and without upper lip twitch restraint. A previous ophthalmic examination was performed with Schirmer tear test, fluorescein test, slit lamp biomicroscopy and direct ophthalmoscopy in all horses. Only healthy animals with no ocular findings were used. The order of the IOP measurements (with or without twitch) and order of the eye (right or left) were randomized. Three measurements of each eye were made and the mean was calculated. Head position was kept above the heart level and no...

Modified extracapsular extraction versus endocapsular phacoemulsification: intraoperative and immediate postoperative events Arq. Bras. Med. Vet. Zootec.
Honsho,C.S.; Oriá,A.P.; Pigatto,J.A.T.; Laus,J.L..
The clinical events and variations in intraocular pressure (IOP) that occur in endocapsular phacoemulsification technique were compared to the modified extracapsular extraction technique during the intraoperative and immediate postoperative periods. Phacoemulsification technique caused less corneal edema, less ocular discomfort and fewer postoperative complications than the modified extracapsular extraction technique. The observed increase in postoperative IOP, especially in the case of phacoemulsification, makes pressure monitoring mandatory, as well as the use of ocular hypotensive agents when the IOP exceeds acceptable limits.

Trabeculectomy and optic nerve head topography BJMBR
Paranhos Jr.,A.; Lima,M.C.; Salim,S.; Caprioli,J.; Shields,M.B..
The objective of the present study was to evaluate changes in optic nerve head parameters, measured by confocal laser tomography, before and after trabeculectomy in order to identify outcome measures for the management of glaucoma. The optic nerve head of 22 eyes (22 patients) was analyzed by confocal laser tomography with the Heidelberg retinal tomogram (HRT) before and after trabeculectomy. The median time between the first HRT and surgery was 4.6 months (mean: 7.7 ± 8.3) and the median time between surgery and the second HRT was 10.8 months (mean: 12.0 ± 6.8). The patients were divided into two groups, i.e., those with the highest (group A) and lowest (group B) intraocular pressure (IOP) change after surgery. Differences in the 12 standard topographic...
