Of the different types of glaucoma, the most common are called open-angle glaucoma and closed-angle glaucoma. [7] Inside the eye, a liquid called aqueous humor helps to maintain shape and provides nutrients. The aqueous humor normally drains through the trabecular meshwork. In open-angle glaucoma, the draining is impeded, causing the liquid to ...

Over many years, glaucoma has been defined by an intraocular pressure of more than 20 mm Hg. Incompatible with this (now obsolete) definition of glaucoma was the ever larger number of cases that have been reported in medical literature in the 1980s and 1990s who had the typical signs of glaucomatous damage, like optic nerve head excavation and thinning of the retinal nerve fiber layer, while ...
Phacomorphic glaucoma is an eye disease that can occur due to a neglected advanced cataract.In this, the mature cataractous lens cause secondary angle closure glaucoma.The presence of an asymmetric mature cataractous lens, shallow or closed anterior chamber angle, raised intraocular pressure (IOP) and other typical signs and symptoms of angle-closure glaucoma in the eye may lead to a diagnosis ...
However, early-stage secondary glaucoma rarely occurs with the readily available prescription of anti-inflammatory medications. On the other hand, late-stage glaucoma is commonly associated with open-angle glaucoma but the mechanisms are currently unconfirmed. Yet, it is believed to be closely related to the onset of trabeculitis or vitreous ...
Determining the anterior chamber depth (ACD) is important in estimating the risk of angle closure glaucoma. There are various methods of measuring ACD, including examination through a slit lamp, ultrasound and Scheimpflug photography. These methods require sophisticated examination equipment and expertise.
