Variation of intraocular pressure comparing rebound (TONOVET Plus®) and applanation (TONO-PEN VET®) tonometry in New Zealand rabbits treated with Amlodipine®

Rabbits have played an important role in ophthalmological research processes, however the environment there has been a deficiency of sensitive equipment measurement intraocular pressure for this species. To compare (IOP) measured with rebound (TONOVET Plus®) and applanation (TONO-PEN VET®) tonometry healthy New Zealand rabbits treated Amlodipine. Twelve male white rabbits, 5 months old; two groups 6 individuals were used study. The experimental group was given Amlodipine® at dose mg/kg, once day month. Blood before treatment h after period one A trend is noted where animals amlodipine® presents lower values than control group, both systolic diastolic pressure. showed average 116.5 ± 7.9 mmHg 117.4 8.9 113.6 111.8 10.0 (pretreatment posttreatment respectively). Tonometry: obtained using TONOVET Plus® (19 3 mmHg) are on higher TONO-PEN VET® (17 mmHg). It possible to demonstrate relationship between systemic blood rabbits. Rebound less variability results tonometry. This study confirmed that tonometers reliable measuring IOP
