Wykorzystanie trabekulektomii chirurgicznej w leczeniu jaskry u psów

Aqueous humor is produced by the ciliary body by active secretion and filtration of plasma. Most of the aqueous humor flows from the posterior chamber, through the pupil, to the anterior chamber, and goes out at the iridocorneal angle into the intrascleral venous plexus. The balance between formation and drainage maintains intraocular pressure. In glaucoma the pressure in the eye increased. Prolonged or recurrent elevation of intraocular pressure lead to degeneration of the retina and optic nerve. The presence of a “red eye”, corneal edema, mydriasis, blepharospasm, blidness, and buphtalmos can be seen. Pupillary light reflex may be slow or absent. Glaucoma is divided into primary (including congenital) and secondary categories. The iridocorneal angle may be open, narrow or closed in either type. Secondary glaucoma is most frequently due to severe anterior uveitis or iris melanoma. Aggressive medical and possibly surgical therapy is indicated for patients with glaucoma that continues to progress despite use of medications therapy. In some cases, trabeculectomy surgery may be recommended. This procedure we applied in the case of our patient.
