"Glaucoma arises due to excess accumulation of Aqueous Humor Fluid (AHF) in anterior chamber of eye. The accumulated AHF increases Intraocular Pressure (IOP) in the eye. Traditionally, IOP of eye measure with airpuff tonometer. Airpuff tonometer cannot be used for continuous monitoring glaucoma i.e. current flow status of AHF in chamber. In reality, intraocular pressure (IOP) is not constant; it fluctuates throughout the day and even hour by hour. IOP is predicted from biomagnetic radiation from AHF of eye. Biomagnetic signal radiation of AHF increases with fluid level. The signals are acquired using GMR spintronic transducer. GMR is positioned at 1.5 cm from cornea of eye for AHF magnetic radiation signal acquisition. GMR sensor fixed close to eye using goggles. GMR signals have artifact due to eyeball movement. The artifacts are saccade, pursuit, smooth, miniature, nystagmus, compensatory and vergence. Eyeball movement lead to noise in GMR acquired AHF signal. The dataset consist of AHF signal acquired during different eyeball movements."
