Device for Detecting Glaucoma
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2019, Vol 14, Issue 1
Abstract
This is a diagnostic device to measure the Intraocular Pressure (IOP) of eyeball, a key indicator for glaucoma. This is a degenerative disease characterized by progressive loss of visual field. According to Glaucoma society of India 12 million people are affected by Glaucoma i.e. 12.8 % of total cases of blindness. About half of glaucoma patients go undetected until they lose substantial vision and suffer from irreversible loss of visual function if untreated. The innovative device being developed is expected to help in early detection, screening, and treatment of glaucoma, the leading preventable cause of blindness. The degenerative disease glaucoma is the world’s leading cause of preventable blindness. Glaucoma stems from optic nerve damage due to a buildup of Intraocular Pressure (IOP) in the eyeball. Normal IOP ranges between 10-21mm Hg. After 23mm Hg, the risk of glaucoma increases by 10% for every additional 1mm Hg pressure. Higher pressure damages the neuronal tissue in the optic nerve head (lamina cribrosa). Current treatment involves reducing the pressure to slow the progression of the disease. This requires accurate methods to measure IOP [1]. The intraocular pressure is a fundamental parameter of ocular health and disease, with major importance in the diagnosis and management of glaucomatous conditions. The most common cause of chronically elevated IOP is a decrease of trabecular outflow. If this state persists, glaucomatous condition may be developed (Figure 1). Unfortunately, nearly 50% of people with glaucoma may go undetected until they have lost substantial vision. Glaucoma stems from optic nerve damage due to a buildup of Intraocular Pressure (IOP) in the eyeball. Normal IOP ranges between 10- 21mm Hg. After 23mm Hg, the risk of glaucoma increases by 10% for every additional 1mm Hg pressure. Higher pressure damages the neuronal tissue in the optic nerve head (lamina cribrosa), (Figure 2). Current treatment involves reducing the pressure to slow the progression of the disease. This requires accurate methods to measure IOP. The innovative device being developed is expected to help in early detection, screening, and treatment of glaucoma, the leading preventable cause of blindness [2].
