Скачать или смотреть What are the different types of glaucoma? - Dr. Sirish Nelivigi

Basically glaucoma is divided broadly into two categories. One is the open-angle glaucoma and other is the angle-closure glaucoma. This differentiation is based on the fact that the fluid in the eye, which is called as the agueous humour is getting produced constantly from one area which we call as the ciliary body and then moves out of the eye to another area known as the trabecular meshwork. Now in certain circumstances, this trabecular meshwork which is at the corner of the eye gets blocked by a natural tissue of the eye, called as iris. When this natural tissue of the eye which is called iris, blocks the trabecular meshwork ,we call this as angle-closure glaucoma. In certain circumstances this tissue keeps the meshwork open, but that can be an inherent molecular level block of the trabecular meshwork. So in such situations we call as the open angle glaucoma. In addition to this the classification of glaucoma can also be based on the causes of glaucoma ,like say for example, when there is a trauma which causes glaucoma, we call it as traumatic glaucoma. When there is glaucoma that comes from childhood , then we call it as juvenile glaucoma, when it occurs from birth we call it as congenital glaucoma. We can have glaucomas due to steroids. So we call it as steroid induced glaucoma. We can have glaucomas caused by various medicatons. We can have glaucomas caused by various diseases in the eye especially conditions like uveitis, which is inflammatory conditions of the eye can cause glaucoma. So we can have glaucomas based which we can classify based on the type of glaucoma like open-angle and closed-angle glaucoma. Then we can have glaucoma based on the causation of glaucoma, say traumatic glaucoma or cataract induced glaucomas.
