Free Content Prevalence of papilloedema in patients with sleep apnoea syndrome: a prospective study

Download Article:

The association of papilloedema (PO) with respiratory diseases and especially obstructive sleep apnoea (OSA) syndrome has been emphasised in many reports. The pathophysiology could rely on the episodic increase of intracranial pressure related to apnoeic episodes during night sleep. Nevertheless, prevalence of papilloedema in patient with OSA syndrome remains unknown. As this information could improve diagnosis and therapeutic strategies, the aim of the present study was to investigate the prevalence of PO in an OSA syndrome population. From 95 successive, recently diagnosed OSA patients, 35 answered a questionnaire about visual symptoms and underwent fundoscopic examination. Visual symptoms suggestive of PO were present in 40% of the patients, but none had PO. As a conclusion, PO does not seem to be frequently associated with OSA syndrome and systematic screening of PO in these patients does not seem to be warranted. Nevertheless, patients with visual complaints evocative of papilloedema should have their eye fundus checked since the association between OSA and PO exists. Further studies, including more patients, might be useful to establish which patients are at particular risk for this complication.
