Abstract

Purpose: To determine the effect of androgen deficiency on the preocular tear film function and lipid composition of meibomian gland secretions. Material and Methods: Twenty eight prostate cancer patients who were on antiandrogen therapy and 20 age-matched controls were included in this study. Patients were questioned for presence of dry eye symptoms and then underwent an anterior segment examination. Tear film functions were determined by Schirmer 1 and fluorescein break-up time tests. Meibomian secretions were obtained from each eye and analyzed by gas chromatography/mass spectrometry . Results: Patients who were on antiandrogen therapy, had significantly higher frequency of dry eye symptoms, conjunctival tarsal injections, lid collarettes, irregular lid margins, orifice metaplasia of the meibomian glands, and had more debris and mucus in their tear film. The tear film meniscus height and the quality of meibomian gland secretions were significantly reduced in the androgen deficiency group, compared to the control group. Patients in the androgen deficiency group had significantly lower Schirmer 1 (left eye) test and shorter tear film break up time test (right and left eyes) values, when compared to the control group. In lipid analysis, diglycerides, saturated and unsaturated free fatty acids were significantly higher, triglyceride and cholesterol levels were lower in the androgen deficiency group. Conclusion: This study indicates that chronic androgen deficiency is associated with meibomian gland dysfunction and dry eye.The changes in lipid composition of meibomian glands may be responsible for this clinical picture.

Özet

Amaç: Androjen eksikliğinin göz yaşı fonksiyonları ve meibomian bezi lipid yapısına etkisini incelemek. Gereç ve Yöntem:Çalışmaya prostat kanseri tanısı ile izlenen ve antiandrojen tedavisi alan 28 hasta ve kontrol grubu olarak da, yaş uyumlu 20 hasta alındı. Hastalarda kuru göz semptomları sorgulandı, tam bir ön segment muayenesi yapıldı. Gözyaşı fonksiyonları; Schirmer 1 ve floresein kırılma zamanı testleri yapılarak değerlendirildi. Her iki gözden meibomian bez sekresyonu toplandı ve lipid yapısı açısından gaz kromatografi-kütle spektrometri ile analize edildi. Bulgular: Antiandrojen tedavi alan hastalarda; kuru göz şikayetleri, konjonktiva kızarıklığı, kapakta telenjiektazi, kapak kenarı düzensizliği, meibomian bez ağızlarında metaplazi, göz yaşında mukus ve debris varlığı daha fazla izlendi. Androjen eksikliği olan hastalarda göz yaşı menisküs yüksekliği ve meibomian sekresyon kalitesi anlamlı derecede azalmıştı. Schirmer 1 testi (sol göz) ve floresein kırılma zamanı testi (sağ-sol göz) sonuçları androjen eksikliği olan grupta; kontrol grubuna göre anlamlı derecede düşük izlendi. Lipid analizinde androjen eksikliği olan grupta digliserit, doymuş ve doymamış yağ asitlerinde anlamlı derecede artış, trigliserit ve kolesterol düzeylerinde ise anlamlı derecede azalış tesbit edildi. Sonuç: Bu çalışma kronik androjen eksikliğinin kuru göz sendromu ve meibomian bez disfonsiyonu ile birlikteliğini göstermektedir. Meibomian bez lipidlerinin yapısındaki değişiklik bu klinik tablodan sorumlu olabilir.
