Abstract

Purpose: To evaluate the effect of systemic isotretinoin treatment on the ocular surface by using conjunctival brush cytology. Material and Methods: Patients who were treated with oral isotretinoin because of acne vulgaris were examined prospectively. A complete ophthalmologic examination was done before treatment and 1 month, 2 months, 3 months and 4 months after treatment. Additionally, conjunctival brush cytology was performed before and 4 months after treatment. Results: Twenty-four patients were enrolled into the study. The mean age of the patients was 20.5±4.3 years. Before and after isotretinoin treatment, there wasn’t significant difference in refraction error, flourescein break-up time and Schirmer I examination. The conjunctival brush cytology results were grade 0 in 75% of the patients (18/24), and grade 1 in 25% (6/24). Four months after treatment, the conjunctival brush cytology results were worsened from grade 0 to grade 1 in 4 cases, from grade 1 to 2 in 2 cases and from grade 0 to 2 in 2 cases. In the remaining of the 16 cases no cytologic change was determined. The cytology results showed statisticaly significant difference in conjunctival metaplasia before and 4 months after isotretinoin teratment (p=0.008). Conclusion: In this study, conjunctival epithelial abnormalities and decrease in number of goblet cells were determined 4 months after oral isotretinoin treatment.

Özet

Amaç: Sistemik izoretinoin kullanımının oküler yüzey üzerine etkisinin konjonktiva fırça sitolojisi ile değerlendirilmesi. Gereç ve Yöntem: Akne vulgaris nedeniyle oral izotretinoin başlanan hastalar ileriye dönük olarak incelendi. Hastaların izoretinoin tedavisi başlamadan önce ve tedaviye başladıktan sonra 1., 2., 3. ve 4. aylarda oftalmolojik muayeneleri yapıldı. Aynı zamanda tedavi öncesi ve tedaviden 4 ay sonra tüm olguların konjonktiva hücre görünümü, fırça sitolojisi ile değerlendirildi. Bulgular: Düzenli kontrollere gelen 24 hasta çalışmaya alındı. Hastaların yaş ortalaması 20.5±4.3 yıl idi. İzotretinoin tedavisi öncesi ve sonrasında hastaların refraksiyon kusurunda, gözyaşı kırılma zamanında ve Schirmer I testinde anlamlı bir değişiklik izlenmedi. İzotretinoin başlanmadan önce yapılan fırça sitolojisinin incelenmesinde %75inin (18/24) evre 0, kalan %25inin (6/24) evre1 olduğu saptandı. Tedaviden 4 ay sonra alınan sitoloji örneklerinde ise 4 olguda evre 0’dan 1’e, 2 olguda evre 1’den 2’ye ve 2 olguda da evre 0’dan 2’ye geçiş olduğu görüldü. Geri kalan 16 olgunun sitolojik bulgularında değişiklik saptanmadı. Dört ay izotretinoin kullandıktan sonraki sitoloji bulguları tedavi öncesi ile karşılaştırıldığında istatistiksel olarak anlamlı derecede konjonktival metaplazi gösterdi (p=0.008). Sonuç: Bu çalışmada 4 ay süreyle oral izotretinoin kullanan hastalarda, tedavi öncesine göre konjonktiva epitelinde anormallikler ve goblet hücre sayısında azalma saptanmıştır.
