[Postoperative behavior of intraocular pressure after posterior Nd:YAG laser capsulotomy--critical evaluation in preventive administration of local carbonic anhydrase II inhibitor dorzolamide hydrochloride (Trusopt)].

Background: The aim of the present study was to examine the influence of the topical carbonic anhydrase-II-inhibitor dorzolamide hydrochloride (Trusopt) in regarding to behaviour of intraocular eyepressure after Nd:YAG-laser-capsulotomy.

Patients And Methods: The study was carried out as a double-blind-test. In a period of nine months, 120 patients underwent Nd:YAG-laser-capsulotomy.

Refractive errors after cryotherapy in retinopathy of prematurity.

Because of acute retinopathy of prematurity 14 premature infants (900-1,630 g birth weight) were treated with cryocoagulation (10 children, both eyes; 4 only one eye) between 1976 and 1984 and were followed up until they were 2-7 years of age. The average refractive power of 20 eyes (those in which refraction could be determined) was -1.5 +/- 4.

Peeling technique for cataracta secundaria associated with posterior chamber lenses.

A new method for removing a secondary cataract with a posterior chamber lens in situ was developed using a specially designed irrigation/aspiration handpiece. In two cases, a focal rupture of the posterior capsule without vitreous prolapse occurred. There were no other serious complications observed in 367 patients who were treated.

[Follow-up after enucleation in choroid melanoma].

We report on 31 patients who underwent enucleation between 1976 and 1984 for uveal melanoma and had a mean follow-up of 107 months. There was no irradiation to the globe or orbit prior to enucleation, which was done under general anesthesia. Histology showed that: the average diameter of the tumors was 10.

[Automatic biometry and keratometry in comparison with the manual technic].

In order to determine the power of intraocular lenses more easily prior to cataract surgery, we compared the results obtained by automatic measurement of the corneal refractive power by the Humphrey Autokeratometer with manually obtained measurements using the Zeiss ophthalmometer. Similarly, the axial length was determined by automatic measurements using the Digital B System IV (Cooper Vision) and manual measurements using the Ophthascan S (Biophysic Medical). Statistical evaluation showed that there were no significant differences in the corneal refractive power determined by the two methods or in the IOL power calculated using the SRK formula.
