The word glaucoma comes from the Ancient Greek word γλαυκός (glaukós), meaning 'gleaming, blue-green, gray'. 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.
Glaucoma is a genus of freshwater ciliates in the Oligohymenophorea. Cells in this genus are between 30–150 μm long, and have three membranelles (structures formed from multiple modified cilia ) that surround the oral cavity. [ 1 ]
The crystalline lens inside the human eye has been implicated as a causative factor in many forms of glaucoma. Lens induced glaucomas or Lens related glaucomas are either open-angle or closed-angle glaucomas that can occur due to a neglected advanced cataract (cloudiness of the lens) or a dislocated lens.
Primary congenital glaucoma is classified into three subtypes: [4] true congenital glaucoma, which causes signs of increased intraocular pressure within the first month of life, infantile glaucoma, which presents between one month and three years, and; juvenile glaucoma, which becomes clinically apparent after three years of age and before age 40.
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 ...
Principal causes of secondary glaucoma include optic nerve trauma or damage, [2] eye disease, surgery, neovascularization, [3] tumours [4] and use of steroid and sulfa drugs. [2] Risk factors for secondary glaucoma include uveitis, [ 1 ] cataract surgery [ 5 ] and also intraocular tumours. [ 5 ]
Phacolytic glaucoma (PG) is a form of glaucoma which is caused due to a leaking mature or immature cataract.Inflammatory glaucoma which occurs in phacolysis is a condition which is a result of the leakage of protein within the lens into the capsule of a mature or hyper mature cataract and involves a simple procedure to be cured that is referred to as cataract extraction.
[4] [19] Another found that PEX was present in 6% of an "open-angle glaucoma" group. [20] Pseudoexfoliation syndrome is considered to be the most common of identifiable causes of glaucoma. [5] If PEX is diagnosed without glaucoma, there is a high risk of a patient subsequently developing glaucoma. [3] Country and region. Prevalence of PEX ...
