    Notes: Abstract A femtosecond pulse laser in the visible spectral region shows promise as a potentially new powerful corneal sculpting tool. It combines the clinical and technical advantages of visible wavelengths with the high ablation quality observed with nanosecond-pulse excimer lasers at 193 nm. A femtosecond and a nanosecond dye laser with pulse durations of 300 fs and 7 ns, and centre wavelengths at 615 nm and 600 nm, respectively, both focused to an area of the order of 10−5 cm2, have been applied to human corneal ablation. Nanosecond laser pulses caused substantial tissue disruption within a 30–100 μm range from the excision edge at all fluences above the ablation threshold of F th≈60 J cm−2 (I th≈9 GW cm−2). Completely different excisions are produced by the femtosecond-pulse laser: high quality ablations of the Bowman membrane and the stroma tissue characterised by damage zones of less than 0.5 μm were observed at all fluences above ablation threshold of F th≈1 J cm−2 or I th≈3 TW cm−2 (3×1012 W cm−2). The transparent cornea material can be forced to absorb ultrashort pulses of extremely high intensity. The fs laser generates its own absorption by a multiphoton absorption process.

    Blepharitis — a diagnostic and therapeutic challenge (1991)

    Notes: Abstract Over the last few years the number of patients with chronic bilateral blepharitis has increased dramatically. From January 1985 until the end of 1989, a total of 407 patients with this diagnosis underwent ophthalmological and dermatological investigations at our out-patient clinic. Keratoconjunctivitis sicca (KCS) in conjunction with blepharitis occurred in 14.5% of the patient population who also suffered from acne rosacea. A comparison of the spectrum of microorganisms that have previously been isolated from affected sites with data obtained in the present study revealed that the range of microorganisms associated with this chronic localized inflammation has apparently shifted in recent years. The prevalence of Staphylococcus aureus, which was considerable in the pre-antibiotic era, has markedly decreased, although a distinct entity of staphylococcal blepharitis seems to remain, either alone or in combination with seborrheic blepharitis (62.8% of our patients). The clinical picture, microbiological findings and therapy for this condition are presented.

    Description / Table of Contents: Zusammenfassung Im Rahmen der Spezialambulanz für infektiöse Augenkrankheiten der 2. Universitäts-Augenklinik wurden in einem Zeitraum von über acht Jahren (vom 1. 1. 1983 bis zum 30. 4. 1991) insgesamt 27 Patienten mit der Diagnose einer „infektiösen Endophthalmitis“ behandelt. Routinemäßig wurden Bindehautabstriche durchgeführt und auf aerobe und anaerobe Bakterien und Pilze untersucht. Bei 19 Patienten (70,4% wurden diagnostische Vorderkammer-Punktionen durchgeführt, bei 22 (81,5%) dann im Rahmen einer Vitrektomie zur Entfernung der infizierten Massen Glaskörper-Proben zum Keimnachweis herangezogen. Auffallend ist bei diesem Patientenkollektiv, daß der Bindehaut-Abstrich im Falle einer intraokulären Infektion äußerst unsichere Resultate zeigt, die nur in 36,84% mit den tatsächlich verantwortlichen Mikroorganismen identisch waren. Bei den letzten 11 Patienten (40,7%) haben wir auch mehrmals Entzündungsparameter im Serum getestet. C-reaktives Protein, Elastase und die leichten Immunglobulin-Ketten (Kappa, Lambda). Klinische Ergebnisse, Mikrobiologie und Therapiemöglichkeiten werden präsentiert und diskutiert.
    Notes: Summary A review of 27 cases of bacterial endophthalmitis diagnosed and treated at the Specialized Outpatient Department for Infectious Eye Diseases at the 2nd Department of Ophthalmology of the University of Vienna over a period of eight years (January 1983–April 1991) is presented. In 70% of the cases the patients had undergone surgical intervention. Conjunctival samples were routinely taken for microbiological investigations (aerobic as well as anaerobic cultures). In 19 patients (70.4%) aqueous specimens were obtained, in 22 cases (81.5%) vitreous specimens collected during vitrectomy for the removal of infected material were used for microbiological diagnosis. The results for the patient population described showed the poor reliability of conjunctival cultures from intraocular infections with only 36.84% being identical with those of the vitreous specimens. In the most recent 11 patients three serological parameters of inflammation were tested on various occasions: C-reactive protein, PMN- elastase and light immunoglobulin chain assembling (kappa/lambda). Clinical results, microbiological findings and therapeutic approaches are presented and discussed.
