Abstract

Purpose

To investigate the prevalence of ocular Demodex folliculorum (DF) in an Irish population. To validate a modified Ocular Surface Disease Index questionnaire and employ it to evaluate the relationship between dry eye symptoms and the presence of DF.

Methods

One hundred and fifty-six subjects were enrolled in an epidemiological cross-sectional prevalence study. Each subject completed a novel questionnaire on ocular symptoms and was assessed for the presence of DF. Data was analysed to assess prevalence and to search for significant links between each symptom and DF.

Results

An overall prevalence of 68% was found. Total mean number of DF found on microscopic examination was 3.83 mites per subject (range 0–25). The presence of symptoms was higher among individuals with DF (P = 0.04). Itch was found to be the symptom most significantly associated with the presence and number of DF (P = 0.025 and P = 0.035, respectively). The questionnaire showed good internal consistency (Cronbach’s alpha; α > 0.7) and good reliability (Intra-class Correlation Co-efficient; ICC > 0.7). The sensitivity and specificity of a positive symptom result using the questionnaire were 70.8% and 46.9%, respectively.

Conclusion

There is a strong association between the prevalence of DF and symptoms, in particular itchy eyes. However, not all patients with DF will be symptomatic. The newly developed questionnaire is a reliable instrument for measuring change in symptoms over a period of time and suitable for observing patient reported outcomes in interventional treatment studies.

Metastase in der periokulären Region

Metastasen Leitthema

Orbitale und periokuläre metastatische Tumoren galten früher als sehr selten. Aber mit der ständigen Aktualisierung von Medikamenten und Nachweismethoden für die Krebsbehandlung werden neue Chemotherapien und Strahlenbehandlungen eingesetzt. Die …

Staging und Systemtherapie bei okulären und periokulären Metastasen

Metastasen Leitthema

Metastasen bösartiger Erkrankungen sind die häufigsten Tumoren, die im Auge diagnostiziert werden. Sie treten bei ungefähr 5–10 % der Patienten mit soliden Tumoren im Verlauf der Erkrankung auf. Besonders häufig sind diese beim Mammakarzinom und …

CME: Wundheilung nach Trabekulektomie

Trabekulektomie CME-Artikel

Wird ein Glaukom chirurgisch behandelt, ist die anschließende Wundheilung von entscheidender Bedeutung. In diesem CME-Kurs lernen Sie, welche Pathomechanismen der Vernarbung zugrunde liegen, wie perioperativ therapiert und Operationsversagen frühzeitig erkannt werden kann.

„standard operating procedures“ (SOP) – Vorschlag zum therapeutischen Management bei periokulären sowie intraokulären Metastasen

Metastasen Leitthema

Peri- sowie intraokuläre Metastasen sind insgesamt gesehen selten und meist Zeichen einer fortgeschrittenen primären Tumorerkrankung. Die Therapie ist daher zumeist palliativ und selten kurativ. Zudem ist die Therapiefindung sehr individuell. Die …
