Anterior vitriotomy for aphakic flat anterior chamber.

In a retrospective study of flat anterior chamber after cataract extraction, which was carried out at the University of Illinois Eye and Ear Infirmary (I959-I970), an incidence of 7-58 per cent. was found among 8,553 cases. Re-formation of the anterior chamber usually occurred after therapy with mydriatics (Reese, 1949), miotics, acetazolamide (Thorpe, 1954), or osmotic agents (Jaffe and Light, I966). Surgical therapy, consisting of air or saline injection into the anterior chamber (Kronfeld, 1957), drainage of choroidal detachments (Kronfeld, I957), or iridectomy (Chandler and Johnson, I947), was required for aphakic eyes with flat anterior chamber unresponsive to medical therapy. The present communication reports four cases in which aphakic eyes with a flat anterior chamber
