Laser iridocystotomy for bilateral acute angle-closure glaucoma secondary to iris cysts.

PURPOSE: To report laser iridocystotomy for bilateral acute angle-closure glaucoma secondary to peripheral iris cysts. METHOD: Case report. RESULTS: In a 55-year-old man with increased bilateral intraocular pressure, gonioscopy revealed varied angle narrowing. Bilateral angle-closure glaucoma secondary to peripheral iris cysts was diagnosed by ultrasound biomicroscopy. The peripheral iris cysts could not be seen in mydriasis by gonioscopy. Therefore, we decided to perform laser iridocystotomy with argon and Nd:YAG laser. Collapse of the cysts after laser treatment was demonstrated by ultrasound biomicroscopy. At follow-up, 9 months after laser treatment, intraocular pressure had dropped below 20 mm Hg in both eyes without further therapy. The iris cysts did not recur, which was demonstrated by ultrasound biomicroscopy. CONCLUSIONS: Peripheral iris cysts may produce angle closure and may cause secondary angle-closure glaucoma. If transpupillary laser cystotomy is not possible, laser iridocystotomy may produce collapse of the iris cysts and correction of secondary angle closure.

[Pseudoexfoliation (PEX) syndrome and intraoperative complications in cataract surgery].

BACKGROUND: Conventional wisdom holds that pseudoexfoliation syndrome (PEX) leads to an increased risk during cataract surgery with regard to zonular dialysis, rupture of the posterior capsule and luxation of the lens into the vitreous as a consequence of insufficient zonules. The present study is focused on the impact of pseudoexfoliation syndrome on the outcome of cataract surgery. PATIENTS AND METHODS: We included in a prospective study 1210 patients which underwent cataract surgery (phacoemulsification) and implantation of a posterior chamber lens in our department from October 1997 until June 1999. The course of surgery, relevant associated diagnoses, and intraoperative complications are described. The patients were divided in a PEX-group and non-PEX-group. RESULTS: There was no difference in the percentage of glaucoma patients between the PEX-group (16.2%) and non-PEX group (17.7%). There were statistically significant more women in the PEX-group and the average age was higher. Intraoperative complications, such as rupture of the posterior capsule, zonular dialysis and displacement of the lens into the vitreous body were similar in the two groups. CONCLUSION: This present study shows, that modern cataract surgery makes it possible to achieve good operative results, even in risk patients. Preoperative presence of PEX had no influence on the complication rate of cataract surgery.

[The revised PEDINFUS computer program for total and added parenteral nutrition in children].

The computer program PEDINFUS, first described in 1991, has been fundamentally revised and further developed. The area of application has been considerably widened as additive parenteral nutrition has been included and the group of newborn and preterm infants has been taken into account. Consequently, the program can be used for children of all age groups. In addition, the program has a graphical user interface and can be used on several hardware platforms. The flexibility of the program has also been increased to a considerable degree. Now the nutrient amounts per kilogram per day, the limits of the laboratory values, the combination of enteral food and infusion solutions, and the already drawn-up infusion plans can be changed at liberty. Considerably more matters of clinical interest accompanying parenteral nutrition have been integrated in the program. Further plausibility controls have also been introduced to achieve greater certainty in the calculation of the infusion solutions. In consequence, the preconditions for ensuring and controlling the quality of infusion therapy regimens can be established on an improved level.

[Computer program for improved diagnostic coding in ophthalmology based on the expanded ICD 10].

BACKGROUND: The coding of ophthalmological diagnoses is a long-standing problem that has recently been highlighted by the planned introduction of ICD 10. METHODS: Using an alphanumerical classification system for the first time, ICD 10 offers the space needed for necessary expansion without leading once again to dislocations in the numbering system. The FoxPro 2.5 database system was used to create a program based on an expanded ICD 10 that can be applied from DOS and Windows. RESULTS: ICD 10 was expanded by the addition of a numerical fifth digit, thus increasing the number of classifiable ophthalmological disorders by a factor of 4.2 from 390 to 1635. The new program greatly facilitates the handling of this substantial amount of data. CONCLUSIONS: The enhanced diagnosis coding achieved with the expanded ICD 10 permits nosologically exact statistics to be kept for use as a basis for further scientific work.

[PEDINFUS computer program for total parenteral nutrition of children].

The computer program PEDINFUS permits the fast and simple definition of the individual nutrient amounts and infusion volumes in accordance with age, weight and possible metabolic complications for children up to 18 years. All components needed for total parenteral nutrition are taken into account. The conditions necessary for the optimal satisfaction of the individual needs of each patient by means of combined solutions have thus been created.
