Glaucoma are frequently characterized by ocular discomfort blindness and increase intraocular pressure (IOP). Glaucoma is still a diagnostic and therapeutic dilemma. Surgical intervention and chemical ablation of the ciliary body is prefered method in case of glaucoma in blind eye and always associated with a high risk of failure or reactivation of the inflammatory disease.


In this case use transscleral cyclophotocoagulation (TSCPC) for control intraocular pressure of traumatic glaucoma dog.


Siberian Husky, male, 3-month-old dog was referred with problem, cloudy right eye and increased intraocular pressure (IOP).The dog suffered from an accident. Physical eye exam revealed severe corneal edema with bullous keratopathy, deep perilimbal hyperemia, IOP 36 and blindness. First the dog was treated by medication but poor control and then used TSCPC (DioVetTM - Iridex) and combine with medication. Ophthalmic evaluation application tonometry (Tono-Pen Vet - Riechert) and fundus camera (Smartscope, Acrivet) were perform on day 2, 6, 15, 30, 40 and then every month until 6 months after TSCPC.


The dog has IOP decrease in range 9–21 mm Hg by completion of the evaluation period and vision back. No serious side effects such as activation of the inflammatory process or persistent hypotonia were observed but fundus photograph has showed permanently optic cup and tapetal hyper-reflex.


Transscleral cyclophotocoagulation is safe, less complication and effective procedure for the treatment of traumatic secondary glaucoma. Transscleral cyclophotocoagulation may become the surgical procedure of choice in treating secondary glaucoma and used to reduce parameters for application.
