Effect of four irrigation solutions on the intraocular pressure and total bacterial count of the normal eye in dogs

Abstract

There are numerous agents that have been used for irrigation of the ocular tissue from attached foreign bodies, inflammatory exudate and microorganisms. For evaluation of four agents of these irrigation solutions, sixteen clinically healthy dogs of both sexes were used in this study. The dogs were allocated into four equal groups. The right eye of dogs for each group was irrigated 3 times daily for three successive days. The groups were irrigated as following: The first group: ringer’s lactate, the second group: normal saline 0.9%, the third group: boric acid 2% and sodium bicarbonate 1% was used for the fourth group. The left eye was considered control one. The results revealed that the four solutions did not cause any obvious alteration of the eyes and change the intraocular pressure (IOP). According to their effects on the total bacterial count, the four irrigation solutions had not any significant effect. It could be concluded that all of these agents may be used for irrigation of the intact eye and removal of the attached exudate and foreign bodies.
