Relationship between Daytime Sleepiness and Intrinsically Photosensitive Retinal Ganglion Cells in Glaucomatous Disease.

Patients with glaucoma showed to have higher daytime sleepiness measured by Epworth sleepiness scale. In addition, this symptom was associated with pupillary reflex and polysomnography parameters. These ipRGC functions might be impaired in patients with glaucoma, leading to worse quality of life.

Intrinsically photosensitive retinal ganglion cell activity is associated with decreased sleep quality in patients with glaucoma.

Purpose: To use the pupillary light reflex and polysomnography to evaluate the function of intrinsically photosensitive retinal ganglion cells (ipRGCs) and to correlate this function with structural damage in glaucoma.

Design: Cross-sectional study.

Participants: A study was conducted on both eyes of 45 participants (32 patients with glaucoma and 13 healthy subjects).
