Acute Angle-Closure Glaucoma (cont.)

Is Follow-up Necessary After the Initial Treatment of Acute Angle-Closure Glaucoma?

Because one may experience temporary increases in IOP after an iridotomy, IOP is checked one hour after laser treatment. A visit is then arranged for the next day. At this visit, the health care provider examines the eye and IOP is checked again. The other eye will probably be examined at this time, so the health care provider can determine if it is at risk for angle-closure glaucoma and possibly prevent its occurrence.

The patient should continue using the medicines that were chosen to treat the acute attack of glaucoma for 1 day after leaving the hospital or clinic following the iridotomy; after one day, the patient may stop taking these medications. To help reduce any inflammation, the ophthalmologist may also prescribe corticosteroid drugs for one week following surgery.

If a laser iridotomy is not successful in reducing the pressure, an ophthalmologist may repeat the gonioscopic examination to rule out the presence of peripheral anterior synechiae. If peripheral anterior synechiae are found, the patient may need a laser gonioplasty or a surgical iridotomy. If plateau iris is found and continues to cause intermittent elevation of intraocular pressure, lens extraction may be necessary. The eye doctor will discuss the next appropriate step in the patient's treatment plan with him or her.

Is It Possible to Prevent Acute Angle-Closure Glaucoma? What Is the Prognosis of Acute Angle-Closure Glaucoma?

Regular eye examinations with an ophthalmologist may identify people who are at risk for acute angle-closure glaucoma. In some people who are at high risk, a laser iridotomy may be performed to prevent an attack of acute angle-closure glaucoma. If a patient has developed primary acute angle-closure in one eye, the ophthalmologist may suggest laser iridotomy in the other eye to prevent an attack.

The prognosis for acute angle-closure glaucoma is favorable with early detection and treatment. Vision loss can occur without prompt treatment. If pain and/or decreased vision occur, the patient should promptly seek professional treatment from an ophthalmologist.
