[Selected cases of metastatic tumors to the visual system]. / Wybrane przypadki przerzutów nowotworowych do narzadu wzroku.

Metastases are always bad prognostic symptoms. They occur rather rarely, but may involve each element of visual system uni- or bilaterally. Usually we found these metastatic tumors in patients with earlier diagnosed neoplastic disease, in various tissues and organs. Therefore, in majority of cases treatment is only palliative, especially in those with the only eye or when the process is bilateral.

[Effect of breaking up of the anterior border membrane of the vitreous body on the localization of anterior-chamber intraocular lenses]. / Wplyw przerwania blony granicznej przedniej ciala szklistego na lokalizacje soczewki przedniokomorowej.

Cataract extraction with implantation of an anterior chamber lens was performed in 83 patients (118 eyes). In 3 patients occurred an intraoperative breaking up of the anterior limiting vitreous membrane. It had no influence on the early or late localization of the implanted lens. In the postoperative course one could observe the breaking up of the anterior limiting vitreous membrane in 1 case only; the vitreous pucker caused a delicate deflection of the implanted lens without causing any deterioration of the visual acuity.
