Since it was first described, A number of noninfectious etiological theories have been proposed including autonomic dysregulation, allergy, variation of developmental glaucoma, autoimmune/HLA-Bw54 and abnormality of the ciliary vasculature. [2] Initially, infectious etiologies were not considered because of the episodic nature of the acute attacks.
Glaucoma is a group of eye diseases that can lead to damage of the optic nerve. The optic nerve transmits visual information from the eye to the brain. Glaucoma may cause vision loss if left untreated. It has been called the "silent thief of sight" because the loss of vision usually occurs slowly over a long period of time. [5]
Anterior chamber paracentesis is used in the management of acute angle closure glaucoma, and uveitis. [ 1 ] [ 2 ] It can also prevent a raise in IOP after intravitreal injections . [ 3 ] Aqueous humor collected using anterior chamber paracentesis may be used for clinical diagnosis of infectious uveitis.
Because uveitic glaucoma is a progressive stage of anterior non infectious uveitis, uveitic glaucoma involves signs and symptoms of both glaucoma and uveitis.. Patients with acute non infectious anterior uveitis may experience the following symptoms: pain, blurry vision, headache, photophobia (discomfort or pain due to light exposure), or the observance of haloes around lights.
These provide a statistical summary of the field with one number. Although not used for initial diagnosis, they are essential for monitoring glaucoma progression. [3] They include: Mean deviation (MD): Derived from the total deviation and represents the overall mean departure from the age-corrected norm. [18]
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few ...
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.
Tonometry is the procedure that eye care professionals perform to determine the intraocular pressure (IOP), the fluid pressure inside the eye.It is an important test in the evaluation of patients at risk from glaucoma. [1]
