The iridotomy is a laser procedure type that is basically used to treat or prevent the narrow angle glaucoma. Acute angle-closure glaucoma is associated with a very high intraocular pressure abruptly. It is caused by a problem with space inside the eye, the drain is blocked, the output of the eye fluid is difficult and raises the pressure. It relates particularly in patients with a small eye (hyperopia) and cataract. The growth of the cataract is one of the main factors and fortunately if early diagnosis is made, you can operate and this situation can be prevented. Discomfort present with severe pain, which may be accompanied by like vomiting, blurred vision and redness of the eye. It is considered an ophthalmologic emergency and it is important to monitor and treat both eyes, since the other is also very risky. Iridotomy creates openings in the iris to facilitate drainage of fluid from the eye and prevent acute glaucoma.


The action of the iridotomy is to create communications through the iris to facilitate drainage and fluid exit the eye (aqueous humor). In this way is possible to increase the space inside the eye, preventing pupillary block and an attack of acute glaucoma.


The decision of the iridotomy is done in a complete eye examination. In some cases there may be an urgent need for the eye. One has to consider a combined operation in cases of cataract and glaucoma.


The iridotomy procedure is performed under topical anesthesia, ie putting numbing drops in your eye. The procedure is quick, lasting about 5 minutes. The result of the procedure is very successful, with a very rapid and satisfactory visual recovery. The patient may reinstate your daily life easily.

This procedure is successful in most cases a single application. Some patients may have special tissues rebellious and sometimes treatment may require surgery.

It is recommended in patients with a narrow angle to assess the possibility of cataract surgery to increase the spaces in the anterior segment and facilitate drainage of fluid from the eye.
