A case of giant optic disc drusen is presented. Diagnostic difficulties and a role of fluorescein angiography, CT and static perimetry in diagnosing these alterations are described.
The authors presented results of treatment of 230 cases of posterior lens capsule opacities after cataract extraction with IOL implantation. In 200 cases, Nd: YAG laser of Q-Switch type was applied, in 30 capsulotomy was made with classic surgical method through pars plana. Both methods were highly efficacious. The most common complications after laser capsulotomy were traces on the lens and increase of the intraocular pressure. No retinal complications were observed. After surgical incisions of the posterior lens capsule, in some cases inflammatory reactions occurred and, in 3, retinal complications. They were retinal detachment in 2 eyes and macular edema in 1 eye. Follow-up of the patients treated with laser was 3 years and those with surgical method 5 years.
The connection between the values of the intraocular pressure before cataract surgery and the number of intraoperative complications was checked. It was established that the preoperative hypotony improves in an essential manner the operative conditions and influences favourably the decrease of the number of complications in the course the surgery. It was confirmed that the manual massage of the eye is equally efficient and less influencing generally the patient than the pharmaceutical lowering of the IOP.
The IOP was measured in large groups of patients with an implanted posterior chamber lens with or without the use of natrium hyaluronate. It was established that implantation of an artificial lens alone does not influence the value of the intraocular pressure. In cases when natrium hyaluronate was used the pressure was slightly higher but only exceptionally it exceeded 35 mm Hg (most frequently in persons with glaucoma existing before the cataract extraction). The IOP was controlled in the course of several days in all the patients without any harmful consequences for the visual function.
