1. Iridectomy.?I make it a rule to perform an iridectomy in nearly every case, and am of opinion that it is the safe course to pursue in moat cases ; for in the past 158 (cases) I have not had a single prolapse of the iris, and as our patients are mostly illitarate, it is not so absolutely essential to give them the slightly better vision gained by leaving the iris intact at the risk of prolaps...

Sir,?I must plead guilty to having performed many iridectomies unintentionally, and at the same time point out the cause of this little accident in most of my cases. This was a "bellying" of the blade of the Grafe's knife. If instead of the knife being, except at the point, of equal thickness and width there be a " belly " or greater width in the forepart of the blade, leaving the part near the...

In the aphakic eye, with intact iris diaphragm, silicone oil has frequently caused a pupillary block. In this situation aqueous humour accumulates behind the iris and forces silicone oil through the pupil into the anterior chamber. An iridectomy at the 6 o'clock position can effectively prevent this pupillary block. The iridectomy allows free passage of aqueous to the anterior chamber which rem...

A 5-week-old male presented with Peters' anomaly. Corneal transplantation was deferred and the patient underwent an optical sector iridectomy in his better eye with central leukoma and iridocorneal adhesions. At six months following surgery, there was a decrease in corneal opacity. The most recent ophthalmic examination was performed at age 42 months. The cornea was considerably clearer, and th...

PURPOSE To present a novel technique for the implantation of phakic iris-claw intraocular lenses (IOL) in highly myopic cases. METHODS Twelve cases, under the age of 40, with high myopia were included in this retrospective study. The mean follow-up span was 14.4+/-5.8 months. Phakic iris-claw IOL implantation was performed, through a 5.5 or 6.5 mm self sealing scleral tunnel with Bursa techni...

Purpose To report a case of bilateral iridoschisis with cataracts and corneal decompensation in a patient who underwent cataract extraction and superficial iridectomy followed by Descemet membrane endothelial keratoplasty (DMEK). Observations A 58-year-old man with previously diagnosed iridoschisis, cataracts, and diabetes mellitus experienced progressive vision loss bilaterally due to cornea...

Posterior pupillary synechiae affect a proportion of eyes subjected to iridectomy with or without drainage operation because (1) aqueous humour bypasses the pupil; (2) traumatic iridocyclitis occurs; (3) there is immobility of the iris in the iridectomy sector; (4) in eyes with angle closure glaucoma closer apposition of the iris to the anterior lens capsule increases the tendency; (5) pilocarp...
