Is continuous positive airway pressure therapy associated with an increase in intraocular pressure in obstructive sleep apnea?
Patients with OSA demonstrated significant 24-hour IOP fluctuations, with the highest values at night. CPAP therapy causes an additional IOP increase, especially at night. Regular screening of visual fields and the optic disc is warranted for all patients with OSA, especially those treated with CPAP.
Interaural place of stimulation mismatch decreases sensitivity to binaural cues that are important for accurate sound localization. However, deliberate and careful centering of auditory images does not seem to significantly counteract the effects of mismatch. Hence, to obtain maximal sound localization benefits of bilateral implantation, clinical and surgical techniques are needed that take into account differences in electrode array insertion depths across the ears.
