| Summary: |
The consequences of sleep
apneas in patients with obstructive sleep apnea (OSA)
syndrome may influence the function of visual system. In
21 patients with OSA syndrome (apnea / hypopnea index –
AHI 50±20) the detailed ophthalmologic studies,
including tonometry, biomicroscopic evaluation of the
anterior segment of the eye, automatic perimetry and
stereoscopic examination of the eye fundus have been
performed. In 4 patients (19%) the signs of lesions in
the optic tract have been found. These were: defects in
visual field caused by glaucoma (primary open-angle
glaucoma and normal-tension glaucoma) in 2 patients and
defects in visual field (concentric and quadrantic
homonymous) caused by diffuse lesions in the
cortico-nuclear tract in 2 patients. In patients with
the lesions in the optic tract there were severe
disorders of breathing during sleep: AHI >60, mean SaO2
at the end of the apneas <86% and minimal SaO2 at the
end of the apneas <70%. The authors conclude that in OSA
patients there is a high risk of the lesions of the
optic tract as a consequence of severe and repetitive
hypoxemia during sleep. |
