No , glaucoma is not cancer as it is not link to the proliferation of cell mass . malignant neoplastic disease is a purposeless proliferation of cells which can be benignant or malignant whereas glaucoma ’s independent aetiology is increased in intraocular pressure level which damages the optical nerve and thus chair toblindness .
When the intraocular air pressure is more than 21 mm Hg then there are chances of visual nerve degeneration which conduce to sudden painless deprivation of vision .
There is no proliferation of cell in glaucoma but it is related to increased product of sedimentary humour by the ciliary physical structure epithelial cells . When there is an unbalance in production and drainage of sedimentary humor there is an increase in the pressure level on the eyeball . The main drive of decreased drainage of aqueous humor is fibrosis of trabecular meshwork which increases the intraocular pressure .
There can be increased yield of aqueous humor by the ciliate soundbox that is why the major object of maximal drug is beta cells present in the epithelium of ciliary dead body . Thus beta blocker are among the most common drugs that are used for glaucoma as they are targeted against beta cells . aside from beta blocking agent , the alpha protagonist is even used which causes vasoconstriction of line vas present in the ciliary dead body thus decreasing the yield of aqueous humor .
Is Glaucoma Cancer?
Glaucoma is not a tumour , but it is relate with a number of other neoplasm , which are creditworthy for increasing the intraocular force per unit area . If there is any a tumor in the orb which use pressing on the iris can get glaucoma . Like in case of retinoblastoma where there can be endogenous proliferation it can get along to that extent where there is increased pressure on iris from behind . As pressure sensation advances , iris bombe is formed , which campaign forward to block the trabecular meshwork thus precipitate glaucoma . Apart from tumour at times lens thing which is released during the inflammatory procedure can even block the trabecular meshwork thus increase the pressure .
So in curt glaucoma itself is not a neoplasm , but it can be associated with a tumor . So there are various tumors of the orb which can fall glaucoma .
Glaucoma can be of two types of open angle or angle closure . opened - angle glaucoma usually occur when there is trabecular fibrosis or occlusion of trabecula by any atom like electron lens protein or rabble-rousing cells . Whereas slant - closure glaucoma occurs due to adherence of the iris to the lens of the eye which commonly take post when there is mid - dilated state of the pupil . When adhesiveness pass there is an growth in intraocular pressure on ulterior compartment which leads to the geological formation of iris bombe . Once iris bombe is form it , mover , ahead and jam the trabeculae .
If one sees the coin from another side at prison term undetermined - slant glaucoma may appear like a tumour as it also blocks the trabeculate mesh , but indeed it is not because for calling something tumor it should be associated with the proliferation of cell . Few people initially employ to think that there is hyperplasia of ciliary epithelium cells of the ciliary body but this hypothesis is refuse as there is no hyperplasia or hypertrophy rather there is hyperactivity of ciliate epithelium cells of the cilial body . So initially it was considered as glaucoma because of this thoughtfulness , but as it is turn out now so no lit considers it as a tumour . So it would be judicious saying that it is not a tumour itself , but is precipitate by the number of eyeball tumors , which increases the atmospheric pressure of orb .
No matter what make glaucoma initial step of direction is a reduction of pressure sensation which is done by giving acetazolamide , beta blockers , an alpha agonist , and prostaglandin analogue . Plus the intervention of a tumor in case of glaucoma associate with a neoplasm is a must .
