Narrow-angle glaucoma is a condition normally described by the build up of fluids in the iris, the build up finally ends up causing a fatal increment in the intraocular pressure. The condition is one of the causes of irreversible vision in the world. This paper seeks to explain the pathophysiology, manifestation, diagnostic criteria, and treatment options available to Mrs. J who suffers from narrow-angle glaucoma and who lately has been experiencing some tremor and postural instability.
Generally, understanding pathophysiology, manifestations, diagnostic criteria, and the criteria of the condition helps physicians to refer patients who are at high risk like Mrs. J for comprehensive examinations (DiPiro, 2014). To date, the pathogenesis of glaucoma has not been understood, though its related to the death of retinal ganglion. The intraocular pressure in the iris causes straining on the eye’s structures making the retina of the eye to be weaker.

Diagnostic criteria of glaucoma take six steps, that is Tonometry, Ophthalmoscopy, Perimetry, Gonioscopy and Pachymetry. Tonometry test measures pressure found inside the eye, Ophthalmoscopy on the other hand is a test used to examine the optic nerves that are damaged by glaucoma, in order to test, the eye drops are used in diluting the eye pupil (Noronha, 2014). Perimetry tests, is used to produce a clear map of the eye vision field. In order to make a map vison, the patient is asked to a head and then make an indication when light passes through the peripheral. Pachymetry test, a very simple test that encompasses the measurement of how thick the cornea is. It helps in the diagnosis because the thickness of cornea can make an influence on the pressure of the iris.
There are different treatments that Narrow-angle glaucoma patients like Mrs. J can take, one of the treatments being the use of eye drops. The eyedrops are absorbed into the eye system and may control pressure of the eye (Neuhann, 2015). Pills may also be used as treatment for glaucoma, the pills prescribed usually turn down faucets of the eye and reduce the fluids of the eye.
