[Frequency of Nd:YAG capsulotomy after implantation of PMMA and silicon intraocular lenses]. / Frequenz der Nd:YAG-Kapsulotomie nach Implantation von Intraokularlinsen aus PMMA und Silikon.

UNLABELLED: The aim of this investigation was to ascertain the frequency of secondary cataract after implantation of PMMA or Silicone IOLs. PATIENTS AND METHODS: In our series of patients we implanted 900 PMMA IOLs in a period of 4 years. In the following 3 years we implanted 1600 silicone IOLs. After the operation, a Nd:YAG laser capsulotomy was indicated there was a reduction in visual acuity and the patient asked for improvement. With the help of computer documentation we had the possibility to follow up a period of 6 years after PMMA and 3 years after silicone IOL implantation. RESULTS: (1) PMMA IOL: After implantation of PMMA IOLs we found a frequency of 22% capsulotomies during the investigation period of 6 years; 4.9% of them occurred during the 1st year and 8% during the 2nd year. (2) Silicone IOL: During the control period of 3 years we found a capsulotomy rate of 9.9%. Most happened in the 1st year. CONCLUSIONS: Our 22.9% capsulotomy rate after PMMA IOL implantation is lower than the rate mentioned in the literature. We noticed a peak of capsulotomies in the 2nd year after the operation. During a control period of only 3 years after implantation of silicone IOLs we found a capsulotomy rate of 9.9%.

[Acute Borrelia infection. Unilateral papillitis as isolated clinical manifestation]. / Akute Borreliainfektion. Einseitige Papillitis als isolierte klinische Manifestation.

BACKGROUND: Borrelia burgdorferi is the cause of erythema chronicum migrans and Lyme disease. Ticks like Ixodes ricinus are responsible for transmission. Frequently, the tick bite is not noticed by the patient. Eye manifestations, such as keratoconjunctivitis, scleritis, chronic uveitis, vitritis, chorioretinitis, optic nerve disease, orbital myositis and paresis of the eye muscles, often occur after a long period of time and vary greatly. PATIENTS AND METHODS: We present below the case reports of a man 38 years old and a woman of 31, each with manifestation of an ocular Borrelia infection (papillitis and panuveitis, respectively). RESULTS: By antibody-screening with the ELISA technique and Western Blot analysis we were able to prove the serological infection. After specific antibiotic therapy, ocular inflammation improved rapidly, as did visual acuity. The papillitis only healed partially. CONCLUSIONS: In case of therapy-resistant inflammation of the eye we have to exclude general infections because cortisone therapy alone may result in worsening the condition. VECP can be used effectively in the differential diagnosis of papilloedemas. Early diagnosis and therapy of an acute Borrelia infection restrict the extent of the lesions and prevent ocular and general late manifestations. Seronegative values in subjects strongly suspected of having Lyme disease do not necessarily exclude the diagnosis of Lyme disease.
