Hintergrund. In der Vergangenheit konnten wir mit Einsatz der elektronischen intraokularen Nadeldruckmessung zeigen, dass die Applanationstonometrie bei pathologischen Hornhäuten ganz überwiegend falsch niedrige Werte liefert. Ziel dieser Studie war es zu untersuchen, ob bei diesen Hornhäuten die Impressions-Tonometrie genauere Ergebnisse liefert, als die(More)
Background: Applanation tonometry in eyes with pathological corneae can often not be performed or delivers rather questionable results. We report on our 4-year experience with electronic intraocular needle tonometry. Patients and methods: After since 1994 developing and calibrating a system for intraocular needle tonometry, we have performed 395(More)
Background: Problems with epithelial healing are the main cause of corneal graft failure in patients with limbal stem cell deficiency. This post-operative complication cannot be eliminated by conventional penetrating keratoplasty alone, but only by additional limbal grafting, which is, however, highly immunogenic. We report here our 3 years' experience(More)
· Background: The incidence of cytomegalovirus (CMV) retinitis in patients with acquired immunodeficiency syndrome (AIDS) reaches 20–45%. Despite aggressive medical treatment, rhegmatogenous retinal detachments develop in up to 30% of the affected eyes. Surgical repair is often difficult due to multiple, large and hardly visible retinal holes with vitreal(More)
A total of 83 eyes with transsclerally sutured PCLs were followed for an average of 10.5 months (range 2–23 months). The vast majority of patients benefitted considerably from the procedure; 8% of cases experienced a reduction in visual acuity and 2% suffered monocular visual loss. General vascular risk factors seemed to be important in bringing about(More)
· Background: Cytomegalovirus (CMV) retinitis is the most common opportunistic ocular infection in AIDS patients. Cidofovir has proved to be highly effective in treatment of CMV retinitis. Iritis and bulbar hypotony are known as the major complications after intravenous and intravitreal use of this antiviral drug. Cystoid macular edema (CME) after(More)
PURPOSE To ascertain the benefit from radiotherapy in age-related macula degeneration in a single-arm longitudinal study. METHODS AND MATERIALS From 1997 to 1998, 39 patients with occult and 33 patients with classic choroidal neovascularization (CNV) were irradiated with 16 Gy. Fluorescein angiography and measurements of visual acuity were performed(More)
Background: CMV retinitis is the most common opportunistic ocular infection and the main cause of blindness in AIDS patients with a T-helper cell count ≤ 50/μl. Cidofovir is a nucleotide analogue with a long half-life time after phosphorylation intracellularly. It is effective against CMV and can be given intravenously and intravitreally. The aim was to(More)
Hintergrund.“Highly active antiretroviral therapy” (HAART) führt bei Patienten mit der Immunschwäche Aids zu einer teilweisen Rekonstitution ihrer Immunkompetenz. Ein Anstieg der CD4-Zellen und ein Absinken der Viruslast sind dafür die wichtigsten Verlaufsparameter. Durch diese verbesserte Immunlage sinkt das Risiko für opportunistische Infektionen. Eine(More)
