Glaucoma Powerpoint Presentations
Pathophysiology of glaucoma revolves around the aqueous humour dynamics. The principal ocular
structures concerned with it are ciliary body, angle of anterior chamber and the aqueous outflow system.
Angle of anterior chamber
Angle of anterior chamber plays an important role in the process of aqueous drainage. It is formed by root of iris, anterior-most part of ciliary body, scleral spur, trabecular meshwork and Schwalbe’s line (prominent
end of Descemet’s membrane of cornea). The angle width aries in different individuals and plays a vital role in the pathomechanism of different types of glaucoma. Clinically the angle structures can be visualised by gonioscopic examination
Glaucoma
Glaucoma is not a single disease process but a group of disorders characterized by a progressive optic neuropathy resulting in a characterstic appearance of the optic disc and a specific pattern of irreversible visual field defects that are associated frequently but not invariably with raised intraocular pressure (IOP). Thus, IOP is the most common risk factor but not the only risk factor for development of glaucoma. Consequently the term ‘ocular hypertension’ is used for cases having constantly raised IOP without any associated glaucomatous damage. Conversely, the term normal or low tension glaucoma (NTG/LTG) is suggested for the typical cupping of the disc and/or visual field defects associated with a normal or low IOP.
