摘要:

SummaryThis report involves a retrospective study of five horses with an unusual form of progressive peripheral corneal ulcers. These ulcers were located at the perilimbal region of the cornea and spread both centripetally to mid periphery and circumferentially. Lipping of the epithelial edge was observed often. The depth ranged from superficial to mid stroma. Patients ranged from two and a half to eight years, both sexes, and were referred after a variety of antibacterial therapy. Histories were similar in that all ulcers were initially located adjacent to the limbus in one or more quadrants. No trauma was known to antedate the corneal disease and the patients were in good general health. Conjunctivectomy was performed in three patients which revealed an abundance of plasma cells and lymphocytes. All five cases were negative for a specific bacterial pathogen. Patients responded to a variety of treatment modalities: topical corticosteroid, surgical debridement, therapeutic soft contact lens (TSCL), and/or conjunctivectomy.

摘要:

SummaryThe clinical, gross and microscopic ophthalmic lesions of iridial hypoplasia, limbic dermoids and cataracts in a Quarterhorse stallion and a group of its offspring are described. It is proposed that the lesions in the stallion were the result of an independent mutation and that the defects were transmitted to its offspring by an autosomal dominant gene.

摘要:

SummaryAniridia presents with very characteristic typical signs and has been reported in man (Newell and Ernest 1974), calves (Saunders and Fincher 1951) and horses (Ericksson 1955; Joyce 1983). This case report records aniridia in a Thoroughbred.The animal, a two‐month‐old brown colt, presented with a history of unusual brightness in both eyes and strange behaviour. Clinical examination revealed curtain‐like pigmentation in the upper part of the cornea from the superior limbus which was thickened and poorly demarcated. Some vascularisation was present in the affected corneal region. The iris was absent and the tips of the ciliary body processes were apparent around the lens equator. A small central cataract was present. Intraocular pressure was normal and there were no abnormalities detected on ophthalmoscopic examination of the fundus (Fig 1). The condition was bilateral. Examinations at three and five years of age revealed no further abnormalities.The colt was well developed from birth and although behaving as the other colts, photophobia was evident in the paddock at all times. The horse was quiet in the stable and would sometimes stare in one direction for long periods. It was nervous outside; training was carried out in the early morning as the animal exhibited certain wild behaviour in bright sunshine and reacted sharply to reflected light from pools of water. However, it was placed first on four occasions, second on five occasions and third on one occasion from 37 starts. The colt was gelded at 16 months and was the eighth foal from a mare imported from Ireland; none of the other offspring were affected and the mare showed no evidence of illness during preg
