Abstract:
The study was conducted on sixteen apparently healthy adult mongrel dogs of either sex. The animals were randomly divided into two groups (Group I and Group II) consisting of eight animals each. An injury was created on ventral half of the cornea in the left eye in both groups. In group I, the corneal wound was protected by suturing the third eye lid with the upper eyelid and temporary tarsorrhaphy. In group, II. After 24 hrs, superficial keratectomy of the ventral half of the cornea and temporary tarsorrhaphy were performed. Clinical signs observed were swelling of eye lid. Lacrimation, scratching and pawing, corneal oedema, and vascularization of cornea in both the groups. The animals were kept under observation for a maximum of 30 days. Hemogram and fluorescent dye test was performed at different interval. The incidence of neovascularization and corneal oedema are higher after superficial keratectomy with third eye lid flap and temporary tarsorrhaphy, though complete healing of the cornea occurred within 30 days. Superficial keratectomy followed by temporary tarsorrhaphy is associated with minimal postoperative complications and complete healing occurred within 27 days. The epithelialization of the cornea was complete clinically between sixth and ninth day and can be correctly assessed by fluorescein dye testing. Topical application of Dexamethasone in the eye was found effective to suppress the vascularization of cornea after superficial keratectomy.
