iridectomy

[ī′ridek′təmē]
Etymology: Gk, iris, rainbow, ektomē, excision
surgical removal of part of the iris of the eye. It is performed most often to restore drainage of the aqueous humor in glaucoma or to remove a foreign body or a malignant tumor. An incision is made through the cornea, and the iris is grasped with forceps or a hook and drawn out through the incision. The affected area is cut away, and the elastic iris is allowed to slip back into place. Subjunctival antibiotics may be instilled, and an eye pad is applied. After surgery, the patient is observed for signs of local hemorrhage or excessive pain.

iridectomy

Surgical removal of part or all of the IRIS of the eye, for the treatment of an iris tumour or to allow free circulation of the AQUEOUS HUMOUR. The term ‘peripheral iridectomy’ is used to refer to the production of a small hole in the iris near the root, but this should more properly be called an iridotomy. Iridotomy is usually performed, as an outpatient procedure, with a laser.

iridectomy

The surgical removal of part of the iris. The main reasons for iridectomy are to reduce the intraocular pressure, to enlarge an abnormally small pupil, to excise an iris tumour and, in cataract extraction, to prevent possible blockage of the angle of the anterior chamber. Nowadays, laser iridotomy is preferred in the treatment of angle-closure glaucoma because the incision obtained by this technique can be carried out as an outpatient procedure with only topical anaesthesia, although the cornea must not be hazy (Fig. I16). See iridotomy.
