Zusammenfassung
Hintergrund: Das Ziel dieser Studie war eine Analyse des Geruchssinns bei Patienten mit einem Primäroffenwinkelglaukom. Methoden und Patienten: Geruchsschwelle, Identifikation und Diskrimination wurden bei 30 Primäroffenwinkelglaukom-Patienten und 30 Alter- und geschlechtgematchten Patienten untersucht. Der „Sniffin’ Sticks” Test wurde bilateral durchgeführt, die Ergebnisse gemittelt und mit dem Mann-Whitney-Test zwischen den Gruppen verglichen. Ergebnisse: Die Ergebnisse für die Geruchsschwelle waren 5,9 ± 2,2 und 7,4 ± 2,1 respektiv in der POWG- und Kontrollgruppe (p = 0,01), für die Geruchsdiskrimination 10,5 ± 2,0 und 10,8 ± 1,6 (p = 0,65), und für die Geruchsidentifikation 11,8 ± 2,1 und 10,6 ± 1,6 (p = 0,008). Glaukompatienten mit negativer Anamnese von kalten Hände/Füße (n = 12) haben schlechtere Geruchsschwelleergebnisse erzielt, 4,8 ± 2,6, als Glaukompatienten mit vasospastischer Anamnese (n = 18), 6,6 ± 1,5 (p = 0,036); keine Gruppenunterschiede bei anderen zwei Olfaktionsmodalitäten wurden festgestellt. Schlussfolgerung: Wie bei anderen neurodegenerativen Prozessen, z. B. bei Parkinson- oder Alzheimer-Patienten, scheint der Geruchssinn auch bei Patienten mit primärem Offenwinkelglaukom verändert zu sein.
Abstract
Purpose: The aim of this study was to assess the olfactory function of primary open-angle glaucoma patients. Patients and Methods: We analyzed odour threshold, identification, and discrimination in 30 primary open-angle glaucoma patients and 30 age- and gender-matched healthy control subjects. The ”Sniffin’ Sticks” test battery was applied sequentially on both sides, scores of two nostrils were averaged and means were compared with Mann-Whitney U-test between the groups. Results: Scores for odour threshold were 5.9 ± 2.2 and 7.4 ± 2.1 in glaucoma and control group, respectively (p = 0.01), for odour discrimination 10.5 ± 2.0 and 10.8 ± 1.6 (p = 0.65), and for odour identification 11.8 ± 2.1 and 10.6 ± 1.6 (p = 0.008). Comparing within glaucoma group between those with (n = 18) and without history (n = 12) of cold hands and feet, the former had significantly better odour threshold scores, 6.6 ± 1.5, than the latter, 4.8 ± 2.6 (p = 0.036); no difference in other two olfactory modalities were detected. Conclusion: Changes of olfactory function have been described in neurodegenerations such as Alzheimer and Parkinson diseases. Complex alterations of olfactory performance seem to be present in POAG patients as well.
