Animal welfare related to evaluate intraocular pressure in anatolian buffaloes: Preliminary report

Abstract

One of the main cause of stress in livestock is the vision problems. The goal of this study was to determine Intraocular Pressure (IOP) in Anatolian Buffaloes (AB) by means of applanation tonometry using Tono-Pen XL for the investigation of a stress factor in welfare of the anatolian buffaloes. A total of 2118 eyes were examined from 1059 apparently healthy AB aged between 1 and 8 years old from both sexes. IOP of AB were measured with Tono-Pen XL three times for each eyes in the morning at noon and in the evening during afternoon examination. IOPs of the left eyes were found to be 22.05±2.68 mmHg (range 16.5-27.3 mmHg) whereas the right eyes were 22.07±2.68 mmHg (range 16.1-27.0 mmHg). Comparison of the tonometry between the right and left eyes of AB showed no significant difference. IOP was decreased in accordance with the age of the animal. To the knowledge, this is the 1 st report of tonometrical investigation performed in AB. It was determined that IOP for AB could be 22.05±2.68 mmHg (range 16.1-27.3 mmHg). © Medwell Journals, 2011.
