Uso de éter dimetílico, propano e isobutano no tratamento de simbléfaro em felino doméstico: relato de caso

Abstract

Symblepharon is the formation of adhesions between the corneal and conjunctival surfaces or between different conjunctival surfaces. Infection by Feline Herpesvirus type 1 (FHV-1) is one of the main causes related to this ophthalmic disorder in domestic cats. The objective of this report is to describe a clinical-surgical case of a female feline patient, mixed breed, spayed, 10 months old, seen at the Veterinary Hospital of the Federal University of Paraíba and diagnosed with bilateral symblepharon. Ophthalmic examination revealed corneoconjunctival adhesions in both eyes, epiphora, and ocular discharge. The right eye also exhibited limited movement of the eyeball and visual deficit. The animal underwent surgical treatment using the techniques of lamellar keratectomy and conjunctivoplasty to dissolve the adhesions, in association with cryotherapy using diethyl ether, propane, and isobutane (Pointts®) to prevent re-adhesions. Postoperative care included anti-inflammatory and lubricating eye drops and antibiotic ophthalmic ointment. The animal showed good clinical progress during the 21-day postoperative period, suggesting a promising outcome with the combination of surgery and cryotherapy. However, long-term observation of the patient's clinical condition is necessary to rule out the possibility of relapses and confirm the procedure's effectiveness.
