[The applications of three-dimensional ultrasound scans in ophthalmology]. / Zastosowanie trójwymiarowej ultrasonografii w okulistyce.

Development of ophthalmology in recent years is connected with perfecting diagnostic methods and equipment. Ultrasound examination, because of its good availability, repetitiveness and non-invasiveness has become a commonly used method in ophthalmic diagnosis. Three-dimensional ultrasound (3DUS), also called three-dimensional ultrasound tomography, is an advanced method based on digital analysis of series of two-dimensional images. This technique is especially useful in ocular oncology, vitreoretinal pathologies and ocular trauma. Authors present selected cases visualised using 3DUS technique and discuss its advantages in comparison with traditional two-dimensional scans.

[Massive choroidal hemorrhage as a late trabeculectomy complication ]. / Masywny krwotok podnaczyniówkowy jako pózne powiklanie trabekulektomii.

The purpose of this paper was to present the case of an unusual late complication of filtering glaucoma surgery. A massive choroidal hemorrhage occurred 5 years after trabeculectomy and extracapsular cataract extraction. The diagnosis was confirmed by MRI examination. Improvement in choroidal status and in visual acuity (from hand motions to 6/12 with aphakic correction of 12 diopters) was observed during three weeks of medication. The retina and the choroid remained attached during two years of observation.

[Refraction changes after cataract extraction with IOL implantation in the eyes with previous performed vitrectomy]. / Zmiany refrakcji po operacji zacmy z wszczepieniem sztucznej soczewki wewnatrzgalkowej w oczach po uprzednio wykonanej witrektomii.

PURPOSE: To determine differences between the predicted and postoperative refraction after cataract extraction with intraocular lens implantation in the eyes, which previous underwent vitrectomy. MATERIAL AND METHODS: Fifty three eyes of 52 patients underwent the analysis: twenty five in group I, nineteen in group II and nine eyes with previous scleral buckling in group III. All the eyes had ECCE and IOL with PMMA implantation after vitrectomy. In groups II and. III silicone oil tamponade was used and removed before cataract extraction. Thirty eyes of the control group K underwent cataract surgery and IOL implantation alone. The IOL power calculation was performed with SRK II formula. The predicted and postoperative refractions were compared. The follow-up was minimum 4 months (on average 15 +/- 12.71 months). RESULTS: The postoperative refractions were significantly shifted toward myopia than it was predicted--1.41 +/- 1.21 D in group I, -0.81 +/- 2.11 D in group II and -3.03 +/- 1.49 D in group III. In the control group K the difference was--0.07 +/- 0.91. CONCLUSIONS: Myopic shift of postoperative refraction after cataract surgery should be considered, when calculating the IOL power in the eye after vitreoretinal procedures.
