What Is the Medical Treatment for Glaucoma?

Image
Treatment is designed to lower the IOP by reducing production or increasing outflow of aqueous humor. Depending on the type of glaucoma, medications or surgery are used. IOP usually can be lowered using different medications in the form of eyedrops (see How to Instill Your Eyedrops) and oral or IV medications. What Are the Medications for Glaucoma? Beta-adrenergic blocking agents, alpha-adrenergic agonists, and prostaglandin analogues are some of the most commonly used medications. Beta-blockers, such as timolol (Timoptic), can reduce the amount of aqueous humor produced. Alpha-adrenergic agonists, such as brimonidine (Alphagan), decrease the production of aqueous humor and also improve the drainage of aqueous humor. Another group of drugs called prostaglandin analogs have recently been used. One that may be prescribed is latanoprost (Xalatan). They work near the drainage area within the eye to increase the secondary route of aqueous humor outflow in order

What Are the Exams and Tests for Glaucoma?

Many different methods are used to measure pressure within the eye. Other tests determine whether you have glaucoma and how advanced your glaucoma may be. Most diagnostic tests need to be repeated on a regular basis to follow the presence or progression of glaucoma. Air puff test: The "air puff" test is the most common. This test is a way to measure the IOP without having to actually touch the eye. For this test, you sit in front of a machine with your chin resting on a brace. The eye doctor points a small jet directly at your eye. This jet then delivers a quick puff of air onto the surface of your eye. By measuring the response of the eye to the puff of air, the doctor can make a rough estimate of the intraocular pressure. This is a good screening test for elevated IOP, but it is not very accurate. Direct tonometry: Direct tonometry on the surface of the front part of the eye is a much more accurate measurement of IOP. It, however, requires greater skill and

CATARACT: SYMPTOMS, PREVENTION AND TREATMENTS

Image
A cataract is the muddying of the normally functioning lens of the eye. For individuals who have cataracts, seeing through cloudy eye lens is somewhat similar to glancing through a chilly or misted-up window. Obfuscated vision brought about by cataracts can make it increasingly hard to read anything, to drive a vehicle (particularly around evening time) or to see anyone’s face.  Most cataracts grow gradually and don't upset eyesight from the get-go. However, with time, cataracts start interfering with the person’s vision.  In beginning, more grounded lighting and eyeglasses can assist the individual with managing cataracts. However, whenever vision becomes weaken enough, it’s time to get the cataract surgery.Luckily, cataract surgery is a commonly protected and compelling method to regain the normal vision.  There are many forms of Cataract: - 1. Cataract with Old Age 2. Congenital Cataract (People who are born with Cataracts.) 3. Secondary Cataract due to

GLAUCOMA: DEFINITION, SYMPTOMS, CAUSES, TYPES AND TREATMENT

What is Glaucoma? Glaucoma is an eye-illness in which damage is caused to the optic nerve. The optic nerve is responsible for sending visual information to the brain. The brain can’t interpret the information without any signals from the optic nerves. In most cases, Glaucoma is caused due to unusually high pressure inside the eye with age. That high pressure becomes the chief reason for eroding the nerves; thus leading to vision deficiency or blindness.  Symptoms of Glaucoma Open-Angle Glaucoma is the most recognized Glaucoma in the world. It has no signs or indications aside from slow vision loss with time.  Other cases of Glaucoma might show symptoms such as: - 1. Severe eye pain 2. Nausea 3. Vomiting  4. Redness in the eye 5. Sudden Blurred Vision Causes of Glaucoma What causes pressure imbalance in the eye isn’t known specifically, however ophthalmologists attribute it to certain factors such as: - 1. Eye Drops for Dilating 2. Ce

What Symptoms and Signs May Be Associated With Eye Pain?

Pain is a variable measure. Each person may interpret pain differently. Discomfort in the temple area or the forehead is often due to tensing of the facial muscles after use of the eyes for close work. This is commonly known as eye strain and is usually not associated with any eye disease. Other symptoms often described by those experiencing pain in and around the eye include the following: Partial or complete loss of vision Extreme light sensitivity Tearing Double vision Halos (colored circles or halos around lights) New floaters (spots, strings, cobwebs, or shadows seen before the eyes) Limitation of normal eye movement Pain with movement of the eye in different directions Sensation of flashes or streaks of light Severe headache associated with eye pain All of these symptoms should seek a prompt evaluation from an ophthalmologist or other medical professional. A doctor or an ophthalmologist may see the following signs as evidence of eye problems:

What Facts Should You Know About Eye Pain?

Eye pain is often described as burning, sharp, shooting, dull, gritty, a feeling of "something in my eye," aching, pressure, boring, throbbing, or stabbing. People sometimes confuse pain originating from the eye with other symptoms, such as a headache, sinus pain, toothache, or a migraine. Seek emergency medical care for eye pain if you've experienced a chemical or flash burn, a traumatic event, or have accompanying vision loss. Treatment depends upon the cause of the eye pain. Eye pain is a very common reason for people to seek medical care from their family doctor or an ophthalmologist, a medical doctor specializing in the diagnosis and treatment of eye diseases. What Causes Eye Pain? Causes of eye pain fall into two broad categories: ocular pain and orbital pain. Conjunctivitis is one of the most common eye problems. Conjunctivitis can be an allergic, chemical, bacterial, or viral inflammation of the conjunctiva (the delicate membrane l
