Loss of intrinsically photosensitive retinal ganglion cells in glaucoma may affect sleep quality
Decreased function of intrinsically photosensitive retinal ganglion cells may affect pupillary response and sleep quality in glaucoma patients, according to a study.The cross-sectional study evaluated both eyes of 32 glaucoma patients and 13 healthy subjects using pupillary light reflex and polysomnography to correlate intrinsically photosensitive retinal ganglion cell function and retinal nerve fiber layer (RNFL) thickness with structural damage parameters in glaucoma.
