Abstract

Aim: To determine the effect of smoking on choroidal thickness by using spectral domain optical coherence tomography. Material and Method: 30 healthy smokers whose mean duration of smoking was 5 years (Group 1), 30 healthy smokers whose mean duration of smoking was 10 years (Group 2) and 30 non-smokers (control group) participated in this study. Choroidal thickness (at the fovea and five more extrafoveal points) were measured by using spectral domain optical coherence tomography. Results: Mean age of the Group 1, Group 2 and control group was 32.4 ±5.1 (27-37 years), 34.4±4.6 (28-39 years), 30.1±6.1 (24-38 years), respectively. There were 15 female and 15 male subjects in all groups. Mean average smoking index of Group 1 and Group 2 was 6.4 ± 0.8 (5-9), 11.2±2.3 (10-15), respectively. Mean average choroidal thickness of the Group 1, Group 2 and control group was 262.3±43.2 μm, 224.3±31.2 μm, 311.1±63.1 μm, respectively. The difference between groups was statistically significant in choroidal thickness. Conclusion: We found statistically significant correlation between choroid thickness and chronic smoking. Choroidal thickness decreases with increasing smoking index.

Özet

Amaç: Sigara kullanımının koroid kalınlığı üzerine olan etkilerini spektral optik koherans tomografi (OKT) ile incelemek. Gereç ve Yöntem: Ortalama sigara kullanım süresi en az 5 yıl olan 30 kişi (Grup 1), orta- lama sigara kullanım süresi en az 10 yıl olan 30 kişi (Grup 2) ve sigara kullanmayan 30 ki- şi (kontrol grubu) çalışmaya dahil edildi. Tüm katılımcıların spektral OKT ile foveal ve 5 eks- trafoveal nokta dahil 6 noktadan yapılan ölçümlerle koroid kalınlıkları ölçüldü. Bulgular: Grup 1’de yaş ortalaması 32,4±5,1 (27-37 yaş) idi. Grup 2’de yaş ortalaması 34,4 ± 4,6 (28 - 39 yaş) idi. Kontrol grubundaki olguların yaş ortalaması 30,1 ± 6,1 (24 - 38 yaş) idi. Tüm gruplarda olguların 15’i (%50) kadın, 15’i (%50) erkeklerden oluşmaktaydı. Grup 1’in ortalama sigara içme indeksi 6,4 ± 0,8 (5 - 9) , Grup 2’in ortalama sigara içme indeksi 11,2 ±2,3 (10-15) idi. Grup 1’de koroid kalınlığı 262.3±43.2 μm, Grup 2’de 224.3±31.2 μm, kontrol grubunda ise koroid kalınlığı 311,1±63.1 μm olarak tespit edildi. Koroid kalınlığı açısından gruplar arasındaki fark istatistiksel olarak anlamlı bulunmuştur. Sonuç: Kronik sigara kullanımı ile koroid kalınlığı arasında istatistiksel açıdan anlamlı bir ilişki bulunmaktadır. Sigara içme indeksi artıkça koroid kalınlığının azaldığı görülmüştür.
