“…One could speculate that the high prevalence of OSA in the studies conducted by Pihlblad and Schaefer,2 Gupta et al 3 and Saidel et al 4 in patients with KC could be secondary to the high prevalence of obesity and the higher mean age of their patients; the mean BMI of patients with KC in their studies was 32.4, 31.2 and 29.9, respectively 2–4. The mean age of patients in these studies was 47, 45 and 47 years, respectively 2–4.…”

Ö ÖZ ZE ET T A Am ma aç ç: : Obstrüktif uyku apne sendromu (OUAS) olan hastaların ön segment parametrelerinin kornea topografisi ile değerlendirilmesi ve sağlıklı bireyler ile karşılaştırılmasıdır. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Bu prospektif çalışma kapsamında, 45 OUAS hastasının 45 gözü (OUAS grubu) ve 43 sağlıklı bireyin 43 gözü (kontrol grubu) değerlendirilmiştir. Tüm katılımcıların tanısı göğüs hastalıkları kliniği uyku laboratuvarında polisomnografi yapılarak konulmuştur. Hastaların rutin göz muayenelerinin ardından kornea topografisi ile ön segment ölçümleri yapılmıştır. Grupların merkezi kornea kalınlığı (MKK), dik ve düz keratometri değerleri, ön kamara derinliği (ÖKD), ön kamara hacmi (ÖKH), ön kamara açısı (ÖKA), kornea hacmi (KH), görülebilir horizontal iris çapı (GHİÇ) ve horizontal ön kamara çapı (HÖKÇ) verileri karşılaştırılmıştır. B Bu ul lg gu ul la ar r: : Gruplar arasında yaş ve cinsiyet açısından fark yok idi (p>0,05). Ortalama apne hipopne indeksi (AHI) değeri OUAS grubunda 26,78±23,56 iken, kontrol grubunda 3,00±1,64 idi (p<0,001). Gruplar arasında aksiyel uzunluk, göz içi basıncı, refraksiyon değeri ve görme keskinliği açısından anlamlı fark yok idi (p>0,05). MKK OUAS grubunda 529,28±27,63 µm, kontrol grubunda 522,17±34,17 µm idi (p=0,29). Düz ve dik keratometri değerleri OUAS grubunda sırasıyla 43,21±1,71 D ve 43,87±1,74 D, kontrol grubunda aynı sırayla 42,02±1,35 D ve 43,75±1,84 D olarak bulundu (p=0,23 ve p=0,74). Gruplar arasında ÖKA, ÖKD, ÖKH, KH, GHİÇ, HÖKÇ açısından istatistiksel anlamlı fark bulunmadı (p>0,05). S So on nu uç ç: : OUAS'ta ön segment parametrelerinin normal bireylerden farklılık göstermediği saptanmıştır.A An na ah h t ta ar r K Ke e l li i m me e l le er r: : Uyku apnesi, tıkayıcı; anterior göz segmenti; kornea topografisi A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : To evaluate the anterior segment parameters of obstructive sleep apnea syndrome (OUAS) patients using corneal topography and to compare them with those of healthy individuals. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : 45 eyes of 45 OUAS patients (OUAS group) and 43 eyes of 43 healthy individuals (control group) were evaluated in this prospective study. Diagnostic polysomnography was performed to all subjects in department of chest disease. After routine ophthalmological examination, anterior segment assesment using corneal topography was performed to the control and OUAS groups. Central corneal thickness (CCT), steep and flat keratometry, anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), corneal volume (CV), horizontal visible iris diameter (HVID) and horizontal anterior chamber diameter (HACD) of groups were compared. R Re es su ul lt ts s: : There was no difference in age and sex between the groups (p>0.05). Mean apnea hypopnea index (AHI) value was 26.78±23.56 in the OUAS group and 3.00±1.64 in the control group (p<0,001). There was no difference in axial length, intraocular pressure, refraction, visual acui...

Prevalence of Sleep Apnea Syndrome and High-Risk Characteristics Among Keratoconus Patients

Abstract: Keratoconus patients are at increased risk for sleep apnea, and different risk factors are associated with sleep apnea in keratoconus patients and controls. Ophthalmologists should consider screening keratoconus patients for obstructive sleep apnea, if appropriate.
