A new rodenticide, RH-787, made in Rhom and Hass co. was introduced in this country because it was known relatively harmless to human and beasts. But many internists found that RH-787 induces diabetes in human after accidental ingestions. The effects of RH-787 on various organ are still controversial but the associaton of RH-787 with diabetes is now recognized through the clinical and experimental studies. The cataract is not infrequently seen in juvenile diabetics of several years' duration. In the case to be reported, the cataract was appeared more rapidly within about 2 years after known diabetes due to RH-787 intoxication than usual diabetic cataracts, and the visual results were good after bilateral extracapsular lens extractions with peripheral iridectomy, without any complication.

In the special cases that iris was not naturally prolapsed from the ab externo incision at the peripheral iridectomy for glaucoma(Barkan, Scheie), the iris could be easily drawn out by applying the iris suction which was designed by author. Kong iris suction is similar to the Bell erisophake, but the cup of the iris suction is transparent so that the prolapsing process through the wound could be seen. The peripheral iridectomy with smallest size of the scleral incision can be performed uing the iris suction without introducing the iris forsceps into chamber.

The first clinical trial of the Q-switch Nd:YAG laser iridectomy using Coherent model 9900 in Korea was carried out since March of 1985. 51 eye cases(48 patients) of acute and subacute narrow angle glaucoma were treated with a Q-switched Nd:YAG laser during the last one year and half. The results obtained are as follows; 1) Good results could be obtained by setting 3.0~4.9 mj with mean pulse energy of under 50. 2) Nd:YAG laser iridectomy site and normal intraocular pressure were maintained well. 3) Complications were encountered in 7 eyes(13.7%) but most cases were transitory without permanent damages.

41 cases of complicated cataract in leprosy patients were operated on from May 1989 to March 1990 at National Sorok Island Hospital. In all cases, extracapsular cataract extraction was attempted and sector or peripheral iridectomy was performed. Inferior sphincterotomy was not done in any of the cases. The postoperative results were very satisfactory in most of the operating cases. The results are as follows; 1) Corrected vision above 0.1 was obtained in 29 eyes(70.7%). 2) Corrected vision from F.C. to 0.09 was obtained in 8 eyes(19.5%). 3) Corrected vision below H.M. was obtained in 4 eyes(9.8%). 4) 37 eyes(90.2%) among the total 41 showed an improvement of corrected vision.

Persistent remnants of the pupillary membrane are extremely common, but well-formed membrane which was covering almost entire pupil is very rare. We experienced one case a 15 year-old boy who had extensive dense persistent pupillary membrane with visual disturbance in left eye and optical iridectomy was performed with improvement of vision.

During the last one year. 23 selected cases of various glaucomatous eyes were received trabeculectom y ab extemo (5 X 3mm scleral-flap with a large peripheral iridectomy and only two scleral-flap corners sutures) under surgical microscope. Success cases which were controlled ocular tension to normal are 21 eyes(91.3%) out of total 23 glaucomatous eyes. Especially, all 11 eyes of simple open angle glaucoma were obtained excellent normotension after trabeculectomy, But one case of absolute glaucoma was failed because of vitreous prolapse, and another failed case was in group of acute closed glaucoma due to surgical complication of total hyphema(Table 1, 2).

A case of Vogt-Koyanagi-Harada's Sindrome chiefly affected the anterior uvea has been clinically studied with several references. It was a typical one with hearing disturbances and was complicated with a secondary glaucoma. Following the iridectomy the I.O.P. was back to normal limit and with steroid therapy the inflammatory signs were relieved. After a considerabie period the anterior uveitis recurred. In this case the age of the patient was 10 years older than those Parker presented.

Case Report The silicone oil is widely used as an intraocular tamponade after vitrectomy but its complications were frequently found in postoperative period. The cataract was one of the most common complications in the eyes filled with silicone oil. The cataract in the eyes filled with silicone oil can be removed with either the intracapsular or the extracapsular-extraction technique. But these surgical techniques have two major problems: posterior capsular fibrosis and intraoperative loss of silicone oil. We report two cases of complicated cataract in the eyes filled with silicone oil which those were successfully performed by lens aspiration or extracapsular cataract extraction with large posterior continuous circular capsulorhexis and basal iridectomy without any loss of silicone oil under the continuous positive pressure achieved with an anterior chamber maintainer such as healon and balaneed salt solution.

PURPOSE: To report the results of anterior vitrectomy for obstruction of the aqueous outflow shunt by prolapsed vitreous strands after trabeculectomy. CASE SUMMARY: Trabeculectomy was performed on a pseudophakic primary open angle glaucoma patient with uncontrolled intraocular pressure under maximum tolerable medical therapy. Three months after trabeculectomy, the bleb flattened and the intraocular pressure elevated. On gonioscopic examination, vitreous strands prolapsed through the iridectomy site obstructing the inner ostium. The maximum tolerable medical therapy and Nd:YAG laser vitreolysis were attempted, but the intraocular pressure was not controlled. Anterior vitrectomy was performed to remove the prolapsed vitreous strands. After anterior vitrectomy, the bleb regained filtering function and the intraocular pressure was stabilized. CONCLUSIONS: In a case with a prolapsed vitreous into the anterior chamber obstructing the outflow shunt of the aqueous humor after trabeculectomy, anterior vitrectomy showed therapeutic effects.
