A case of a Brazilian Terrier puppy presenting diabetic lens opacity that restored transparency after insulin therapy and control of blood glucose levels is reported. This entity has been rarely reported in human beings and has not been reported in dogs before. The rapid glycemic control may have been responsible for the transparency recovery.
Relata-se o caso de um cão jovem, terrier brasileiro, apresentando opacidade lenticular diabética bilateral, a qual regrediu, sendo reassumida a transparência do cristalino após a terapia com insulina e controle dos níveis glicêmicos. Essa afecção tem sido reportada raramente em indivíduos da espécie humana, mas não há relatos de sua ocorrência em cães. O rápido controle glicêmico pode ter sido o responsável pela recuperação da transparência.

Topical effects of chondroitin sulfate, a monosulfated glycosaminoglycan, on the healing of alkali-burned corneas were studied.Forty albino rabbits were divided into two groups (GI and GII, n =20) submitted to corneal ulceration with 3 M sodium hydroxide(NaOH). GI was treated with a topical solution of 5% chondroitin sulfate 4 and chondroitin sulfate 6 and GII was treated with 0.9%physiological saline at 6 hour intervals in both cases. The rabbits were studied over a period of 60 days by biomicroscopy witha slit lamp in order to evaluate blepharospasm, blepharitis, chemosis, conjunctival congestion, ocular secretion, and cornealedema, neovascularization and macula. The fluorescein test was performed daily to monitor the evolution of the ulcers. Theanimals were submitted to eye enucleation for histopathology on the 1st, 3rd, 10th, 30th and 60th day after ulcer induction. Whencompared to GII, GI showed 4 perforations. In the eyes in which no perforation occurred, no clinical or microscopic differenceswere observed between groups, except for ocular secretion, which persisted for a longer time in GII animals. Except for thosewith perforations, the corneas tended to heal, on average, within 30 days. The results permit us to conclude that the 5%chondroitin sulfate solution, when instilled on alkali-burned rabbit corneas did not alter healing when compared to the animalstreated with 0

An unilateral corneal epithelial inclusion cyst in a 7-year-old male Boxer dog is reported. The cyst had been observed for thirty days, was unique, not congenital and only one eye was involved. Seven months prior to the referral the dog had manifested indolent corneal ulcer treated with grade keratotomy and third eyelid flap. The cyst was removed by superficial keratectomy followed by a conjunctival pedicle graft. Recovery was uncomplicated and there wasnt recurrence seven months after the surgery.
Relata-se o caso de um cisto de inclusão epitelial em um cão macho, boxer, com 7 anos de idade. O cisto havia sido observado por trinta dias, era único, não congênito e apenas um olho estava acometido. Sete meses antes da consulta, o cão apresentou ulceração corneana indolente, tratada com ceratectomia e recobrimento de terceira pálpebra. O cisto foi removido através de ceratectomia superficial, seguida de enxerto conjuntival pediculado. A recuperação foi descomplicada e não houve recidiva após sete meses de pós-operatório.
