Idiopathic glaucoma in an 11-year-old crossbred mare.

An 11-year-old crossbred mare was presented with left eye buphthalmia, a mydriatic minimally responsive pupil, locally extensive ventral corneal edema, and corneal striae. Intraocular pressures exceeding 80 mmHg lead to a presumptive diagnosis of glaucoma. Following several days of treatment there was no improvement and enucleation was performed.
