Glaucoma after chemical burns and radiation.

Glaucoma after chemical burns represents a posttraumatic glaucoma, usually open-angle glaucoma. It is a frequent complication of chemical burns, especially with alkali and it can appear in the acute stage or as a late complication. Because of the complications and scars, the treatment is very difficult. Topical treatment is based on AC inhibitors, ß-blockers, α2-agonists. Trabeculectomy, shunts, cyclophotocoagulation, and cryotherapy are the solutions in the late stages. Glaucoma after irradiation is a closing-angle secondary glaucoma. The risk factors such as the radiation dose and the volume of the radiated structure are important in the appearance and evolution of this type of glaucoma. Topical treatment is usually ineffective, the preferable options being laser and surgical treatments. Although it is not a frequently seen pathology, it is important to know how to diagnose and treat this type of glaucoma. There are various options available for treatment, but choosing one is difficult because of the possible complications.

CURRENT OPTIONS FOR SURGICAL TREATMENT OF GLAUCOMA.

The purpose of this study is to review current surgical treatment and new and better alternatives for patients with glaucoma. Glaucoma refers to a group of related eye disorders that have in common an optic neuropathy associated with visual function loss. It is one of the leading causes of irreversible blindness worldwide. Optic nerve damage and glaucoma-related vision loss can be prevented or limited by early diagnosis and treatment. Surgery offers a better control of the intraocular pressure then medical therapy. Nowadays, research continues for improving current surgical alternatives for treatment.
