How Obstructive Sleep Apnea Causes Glaucoma

Scientists at Hokkaido University have found out how ‘Obstructive Sleep Apnea Syndrome’ (OSAS) causes glaucoma. OSAS is a condition in which the person’s breathing stops during sleep for a significant period of time because of upper airway obstruction. Glaucoma is a condition in which optic nerve is damaged irreversibly leading to visual field defects and later serious vision loss. High intraocular pressure is a risk factor for development of glaucoma. In the study, scientists measured [...]

Role of Glaucoma Drainage Devices in Glaucoma Surgeries

Glaucoma causes damage to optic nerve resulting into irreversible loss of vision. There are multiple factors involved but high intraocular pressure (IOP) plays an important role in the process of damage. High IOP is also a factor around which a whole range of treatment modalities revolve. Glaucoma drainage devices of various types are the latest addition to the traditional treatment methods for glaucoma. Known as a “glaucoma drainage device,” “tube shunt,” “glaucoma valve,” or “Seton,” [...]
