This study shows that meibomian gland lipid composition changes in these patients.And with the use of oral doxycyline meibomian lipid composition converts back to normal which results in improvement in preocular film stability and improvement in dry eye symptoms.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Purpose : To determine the preocular tear film function and lipid composition of meibomian gland secretion of patients with acne rosacea.Methods : Twenty one patients diagnosed as acne rosacea and 17 age-matched controls were included in this study.
📊
Key Findings & Data:These acne rosacea patients were examined in two groups; the first group had 8 patients who were taking oral doxycycline and the second group had 13 patients who did not get any treatment.Tear film functions were determined by Schirmer 1 and fluorescein break-up time (BUT) tests.
💡
Conclusion & Impact:This study shows that meibomian gland lipid composition changes in these patients.And with the use of oral doxycyline meibomian lipid composition converts back to normal which results in improvement in preocular film stability and improvement in dry eye symptoms.

Abstract

Purpose : To determine the preocular tear film function and lipid composition of meibomian gland secretion of patients with acne rosacea.Methods : Twenty one patients diagnosed as acne rosacea and 17 age-matched controls were included in this study. These acne rosacea patients were examined in two groups; the first group had 8 patients who were taking oral doxycycline and the second group had 13 patients who did not get any treatment.Tear film functions were determined by Schirmer 1 and fluorescein break-up time (BUT) tests. Meibomian secretions were obtained from each eye and analyzed by gas-chromatography/mass-spectrometry.Results : Acne rosacea patients had significantly higher frequency of dry eye symptoms and lid collarette. The tear film meniscus height and the quality of meibomian gland secretion were significantly reduced in the nontreatment group. Acne rosacea patients in nontreatment group had significantly lower Schirmer 1 (left eye) test and BUT test values. In lipid analysis diglycerides and unsaturated free fatty acids were significantly higher. triglyceride and cholesterol levels were lower in the nontreatment group. relative to treatment and control groups.Conclusion : In acne rosacea. the patients have dry eye symptoms due to insufficient tear production and evaporative tear loss. This study shows that meibomian gland lipid composition changes in these patients.And with the use of oral doxycyline meibomian lipid composition converts back to normal which results in improvement in preocular film stability and improvement in dry eye symptoms.

Özet

Amaç : Akne rozasea´lı hastalarda göz yaşı fonksiyonlarını ve meibomian bezin lipid yapısını incelemek.Yöntem : Çalışmaya akne rozasea tanısı alan 21 hasta ile kontrol grubu olarak yaş uyumlu 17 hasta alındı. Akne rozasea´lı hastalar 2 gruba ayrıldı.İlk grupta oral doksisiklin tedavisi alan 8 hasta. ikinci grupta ise hiçbir tedavi almayan 13 hasta mevcuttu. Gözyaşı fonksiyonları; Schirmer 1 ve floresein kırılma zamanı testleri ile tespit edildi. Meibomian salgıları her iki gözden toplandı ve gaz kromatografi-kitle spektrometri ile analize edildi.Sonuçlar : Akne rozasea´lı hastalarda anlamlı olarak yüksek oranda kuru göz semptomları ve kapak kenarında telenjektazi mevcuttu. Göz yaşı film menisküs yüksekliği ve meibomian bez sekresyon kalitesi. tedavi edilmeyen grupta belirgin olarak düşüktü. Tedavi edilmeyen akne rozasea hastalarında schirmer 1 testi (sol göz) ve floresein kırılma zamanı testi değerleri anlamlı olarak düşüktü. Lipid analizinde. digliserit ve doymamış yağ asitleri tedavi edilmeyen grupta. tedavi edilen ve kontrol grubuna oranla belirgin olarak yüksek; trigliserit ve kolesterol düzeyleri ise belirgin olarak düşüktü. Tartışma : Akne rozasea´lı hastalarda göz yaşı yetersizliği ve evaporasyonla göz yaşı kaybından dolayı kuru göz semptomları oluşmaktadır. Bu çalışma akne rozasea hastalarında meibomian bezin lipid bileşiminin değiştiğini göstermektedir. Doksisiklin tedavisi meibomian bez lipid bileşimini normale çevirerek. preoküler film stabilitesinde ve kuru göz semptomlarında düzelme sağlayabilmektedir
