RETINAL NERVE FIBER LAYER ANALYSIS IN OBSTRUCTIVE SLEEP APNEA

Öz

Objective: To investigate the retinal nerve fiber thickness (RNFL) in patients with Obstructive sleep apnea syndrome (OSAS) and to determine the correlation of ocular changes with the severity of disease.

Material and Methods: 21 patients with Respiratory Disturbance Index (RDI) between 5-29 were included in group 1 and 33 patients with RDI > 29 in group 2. Patients received RNFL measurement with optical coherence tomography (OCT). The difference between the groups and the correlation of RFNL with RDI, mean and minimum O₂ saturation was evaluated.

Results: The mean RNFL was 117.33±7.57 in group 1, 111.91 ±8.64 μm in group2. There was statistically significant difference (p=0.023). RNFL in inferior quadrant was 147.95 ±12.97 for group 1, 137.27±17.94 μm for group 2. The difference was statistically significant (p=0.032). Mean RNFL was correlated with RDI.

Conclusion: There is a significant decreare in RFNL occur in patients with OSAS and changes show correlation with severity of disease. Awareness of relationship helps ophthalmologists to question their patients in terms of OSAS symptoms.

Obstrüktif uyku apne sendromunda retina sinir lifi analizi

Öz

Amaç: Obstrüktif uyku apne sendromu (OUAS) hastalarını retina sinir lifi tabakası (RSLT) kalınlıkları yönünden incelemek ve oküler değişikliklerin hastalığın şiddeti ile ilişkisini belirlemek.

Gereç ve Yöntem: OUAS tanılı 54 hasta göz bulguları açısından değerlendirildi. Respiratory Disturbance Index-Anormal Solunum Olayı İndeksi (RDI) 5-29 olan 21’i grup 1, RDI>29 olan 33’ü ise grup 2 kapsamında sınıflandırıldı. Hastalara Optik Koherens Tomografi (OKT) ile RSLT ölçümleri yapıldı. Gruplar elde edilen veriler açısından karşılaştırılırken, verilerin RDI, ortalama ve minimum O₂ satürasyonu ile olan ilişkileri de incelendi.

Bulgular: Ortalama RSLT grup 1’de 117,33±7,57 μm, grup 2’de ise 111,91 ±8,64 μm olarak ölçüldü.  RSLT’deki incelme istatistiksel olarak anlamlı bulundu (p=0,023). İnferior RSLT grup 1’de 147,95 ±12,97 μm, grup 2’de 137,27±17,94 μm olarak bulundu. Grup 2’deki incelme istatistiksel olarak anlamlı bulundu (p=0,032). Ortalama RSLT ile RDI arasında negatif korelasyon saptandı .

Sonuç: OUAS hastalarında RSLT kalınlığında azalma meydana gelmekte ve bu değişimler OUAS’ın ağırlığı ile korelasyon göstermektedir. Bu iki durum arasındaki ilişkinin bilinmesi hastaların öncelikle göz hekimi tarafından görüldüklerinde olası OUAS semptomları yönünden sorgulanmalarına olanak sağlayacaktır.
