Comparison between the rebound (TD - 8000 portable) and applanation tonometer (Tono-Pen AviaTM) managed by different evaluators for intraocular pressure measurements in rabbits

Abstract This study aimed to compare values of intraocular pressure (IOP) by different tonometers and evaluators (veterinary ophthalmologist specialist veterinary not a specialist). For this, 30 rabbits were used, in all (n = 60 eyes), the IOP was initially measured with rebound tonometer (model TD - 8000 portable, Apramed Indústria e Comércio de Equipamentos Médicos Ltda) and, subsequently, an applanation (portable model Tono-Pen AviaTM®, Reichert Technologies®, USA). With two devices, measurements mmHg performed central region corneas, always same period, professional (specialist) (not Data statistically compared using simple analysis variance test. tonometer, ranged from 7 14 when both evaluators; while 9 15 8 16 non-specialist.
