Ocular proptosis is among the most recurrent ocular affections in Cavia porcellus, occurring from different causes. In this species, displacement of the eyeball may occur due to internal compression caused by the tooth root. The aim of this paper is to report two cases of enucleation and exenteration for correction of ocular proptosis secondary to acquired dental disease syndrome (ADDS). Case report: Two guinea pigs were treated with proptosis of the right eyeball, consanguineous and were affected by dental disease, with tooth root growth of the premolars and reserve crowns, with an aspect of dental intrusion, and alteration of the table occlusal of molars and premolars, promoting force and expulsion of the eyeball. As there was no tissue viability, they were submitted to surgery with enucleation and exenteration techniques and collections of secretion for culture with antibiogram in the pre-and intraoperative period and histopathology of the ocular tissues were performed. Results: The application of surgical techniques proved to be effective for the correction of the installed pathology, with effective healing and aesthetic character. The result of bacterial cultures was positive for only one of the animals, with results of Staphylococcus sp. negative coagulase and Aeromonas sp. pre-and trans-operatively, respectively, being sensitive to the antibiotic of choice. In addition to demonstrating tissue alterations compatible with panophthalmitis and squamous metaplasia, both course with a neutrophilic character. Conclusions: It is concluded that the techniques of enucleation and exenteration are effective in correcting proptosis, and ADDS is one of the main causes of this disease in this species, so clinical follow-up is essential to prevent and/or contain the worsening of the syndrome, preventing the evolve with the need to remove the eyeball.
