OBJECTIVE To provide new and original images of the anterior segment (AS) of the eye of selected Ophidian, Chelonian, and Saurian species and to compare the AS architecture among and within these three groups. ANIMALS STUDIED 17 Saurians, 14 Ophidians, and 11 Chelonians with no concurrent systemic or eye disease were included in the study. PROCEDURE(More)
OBJECTIVE To evaluate the efficacy of bovine pericardium (BP) graft in the treatment of deep melting corneal ulcers in three dogs and corneal sequestra in three cats. PROCEDURE Three dogs with keratomalacia affecting the deep third of the stroma and three cats with corneal sequestrum were evaluated and underwent surgery. Following keratectomy, BP material(More)
OBJECTIVE To describe a case of intracranial meningioma causing visual impairment in a cat, successfully treated by surgery. PROCEDURES An adult neutered male domestic cat was referred with a 10-month history of progressive visual impairment and altered behavior. Investigations included physical, ophthalmologic and neurological examinations as well as(More)
OBJECTIVE To determine the effect of 0.5% tropicamide and the resultant mydriasis on the anterior segment in normotensive dogs using ultrasound biomicroscopy. PROCEDURE Twenty-four dogs without ocular disease underwent ultrasound biomicroscopic examination of both the eyes under general anesthesia. Pharmacologic mydriasis was induced in the right eye of(More)
Differences in visual capabilities are known to reflect differences in foraging behaviour even among closely related species. Among birds, the foraging of diurnal raptors is assumed to be guided mainly by vision but their foraging tactics include both scavenging upon immobile prey and the aerial pursuit of highly mobile prey. We studied how visual(More)
OBJECTIVE To evaluate the use and complications of a penetrating keratoprosthesis implantation in the management of corneal opacification in dogs. METHODS A retrospective clinical study describes the indications for the surgical technique utilized and the outcomes of this procedure in 20 eyes of 19 dogs with blindness of corneal origin. A successful(More)
In both humans and dogs, the primary risk factor for glaucoma is high intraocular pressure (IOP), which may be caused by iridocorneal angle (ICA) abnormalities. Oxidative stress has also been implicated in retinal ganglion cell damage associated with glaucoma. A suspected inherited form of glaucoma was recently identified in Eurasier dogs (EDs), a breed for(More)
The surgical resection of a squamous cell carcinoma in a cat was performed on both the palpebral and nasal aspects of the OD medial canthus. A two-stage surgical technique was employed, involving two different transposition flaps, taking care to maintain eyelid function and estheticism, with a long follow-up.
PURPOSE One of the singularities of the eyes of snakes is the presence of the spectacle, a transparent and vascularized integument covering the cornea. The spectacle is completely renewed during ecdysis. Combined scanning laser ophthalmoscopy (SLO), optical coherence tomography (OCT), and conventional macrophotography were used to image this phenomenon. (More)
OBJECTIVE To describe a means of converting the Kowa RC-2 camera to a digital version. PROCEDURE The optic (OP) and the film portions (FP) of the Kowa RC-2 were separated. The lateral rails were unscrewed from the front plate of the FP. The front plate was detached from the FP. The plate was fixed to an anodized aluminum plate (AAP). The rails were(More)
