These changes to vision typically go unnoticed because one eye can compensate for the other. Glaucomas are a group of eye disorders characterized by progressive optic nerve damage in which an important part is a relative increase in intraocular pressure (IOP) that can lead to irreversible loss of vision. May 26, 2016 - Explore Timothy Joseph's board "Pathophysiology Flowcharts" on Pinterest. Additional copy of chromosome 21 results in elevated expression of many of the genes encoded on this chromosome, leading to variying expression of genes associated with this chromosome. Based on pathophysiology, anatomy glaucoma is classified as close-angle glaucoma and open-angle glaucoma. Hypertension is a chronic elevation of blood pressure that, in the long-term, causes end-organ damage and results in increased morbidity and mortality. Jan. 19, 2018.

There are three common forms of laser surgery for glaucoma: laser peripheral iridotomy: creates a new drainage hole in the iris, allowing the iris to fall away from the outflow channel so fluid can drain out of the eye. This article will review pathophysiology of uveitic glaucoma along with modalities available to control intractable glaucoma. Blood pressure is the product of cardiac output and systemic vascular resistance. Pathogenesis of cataract The lens is composed of specialized proteins (called crystallins), whose optical properties are dependent on the fine arrangement of their three-dimensional structure and hydration.
