Combined iridencleisis and posterior sclerectomy in surgical treatment of glaucoma secondary to uveitis in a dog: a case report

In early diagnosed and causally treated cases of secondary glaucoma, it is possible to save the sight in a glaucomatous eye and to preserve the sight in a healthy eye. The most common causes of secondary glaucoma include anterior uveitis, in which diverse pathological processes can lead to an increase in IOP. In cases of treating glaucoma secondary to uveitis with annular posterior synechiae in connection with peripheral anterior synechiae, iridencleisis is the method of choice. This article presents the results of the eight-month treatment of such a case with iridencleisis combined with posterior sclerectomy. This method makes it possible to increase the area of aqueous humour outflow to the subconjunctival space. The treatment resulted in the reduction of IOP in the left eye from the preoperative value of 72 mmHg to 15 mmHg, which was maintained at a constant level during the eight-month period following the surgery. Sight assessment in the operated eye, carried out on the basis of PLR, menace and dazzle response, brought a moderately positive result.
