Ocular Hypertension

The medical term ocular hypertension is used to any condition in which the pressure inside the eye known as intraocular pressure is higher than normal. In order to measure pressure inside the eye, eye doctor called ophthalmologist uses an instrument named tonometer. In order to determine other problems for your intraocular pressure an oculist can assess the extent of the damage of your drainage system named angle. The ophthalmologist uses a technique named gonioscopy during the examination. Gonioscopy technique is used for checking up the drainage angles or drainage channels in your eyes whether they are open, closed or narrowed. High eye pressure should not be thought about an eye disease by itself. On the contrary, the term ocular hypertension is used to explain people who should be kept under observation more closely. Although ocular hypertension mostly describes an increased intraocular pressure there is no optic nerve damage or or vision loss in it. Rarely encountered complication of ocular hypertension is the vein blockage in the retina known as retinal vein occlusion. The retinal vein occlusion may lead to vision loss. Sex is a risk factor in intraocular pressure and ocular hypertension. Women are mostly tending to intraocular pressure and ocular hypertension than men are. Besides, female could be at a higher risk for ocular hypertension, especially after menopause. However, instead male with high eye pressure may be at a higher risk for glaucomatous damage rather than female. Intraocular pressure is a condition which rises slowly rises with aging. Although ocular hypertension is not an eye disorder yet it is one of the major risk factors for glaucoma. The cause of ocular hypertension is: An imbalance in the production of aqueous humor and drainage of eye fluid in the eye leads to high pressure named intraocular pressure in the eye. The channels can not drain the fluid from inside the eye normally. The excess fluid in the eye raises the pressure.

In other words, please imagine a water balloon. To fill the more water in the balloon results in, the higher pressure inside the balloon. Most of those with ocular hypertension do not practice any signs and symptoms. Due to this reason, an ophthalmologist should examine and rule out any injure or harm to the optic nerve because of the high pressure in regular eye examinations. The risk factors both for ocular hypertension and intraocular hypertension known as secondary glaucoma are: Advanced age, alcohol usage, current medications, eye pain, eye redness, eye surgery, eye trauma, family history, headaches, head trauma, myopia, multicolored halos,nearsightedness, obesity, past illnesses, past surgeries, previous eye disease, past ocular history, race and smoking. For measuring intraocular pressure the ophthalmologist does tests. These tests not only recognize the symptoms of the high eye pressure but besides rule out and diagnose the early primary open-angle glaucoma or secondary causes of glaucoma. The tests are: 1- Visual acuity test: It is done in order to determine a person’s visual acuity. The ophthalmologist wants from him/her to read letters from across a room using an eye chart. This test refers to how well an individual see a point. 2- Microscopic or slit-lamp examination: The oculist using a special microscope named slit lamp examines divisions of eyes such as anterior chamber, cornea, iris and lens. 3- Tonometry: Tonometry is a technique used for measuring the pressure inside the eye. These measurements are done for both eyes on at least two or three times. Pressure measurements are taken at different times of daytime because intraocular pressure ranges from hour to hour in every person.4- Optic nerve examination: Each optic nerve and pathways are examined for any injuries in order to make sure one’s dilation of the pupil. 5- Fundus observation: Optic disk photographs are taken. 6- Gonioscopy: It is done to confirm the drainage angle of one’s eye.
