You cannot underestimate the importance of regular eye exams when it comes to caring for your eyes. Many eye diseases such as glaucoma and macular degeneration may not show symptoms early on. A regular eye checkup with VisionFirst Eye Center might prevent these diseases before they become too advanced.
Diabetic retinopathy is the most common diabetic eye disease and a leading cause of blindness in American adults. It is caused by changes in the blood vessels of the retina.
In some people with diabetic retinopathy, blood vessels may swell and leak fluid. In other people, abnormal new blood vessels grow on the surface of the retina. The retina is the light-sensitive tissue at the back of the eye. A healthy retina is necessary for good vision.
If you have diabetic retinopathy, at first you may not notice changes to your vision. But over time, diabetic retinopathy can get worse and cause vision loss. Diabetic retinopathy usually affects both eyes.
Like many other eye diseases, often there are no symptoms in the early stages of the disease, nor is there any pain. Be sure to have a comprehensive dilated eye exam at least once a year.
However, the first symptom you may notice is blurred vision. This may occur when the lens of the eye swells or the macula—the part of the retina that provides sharp central vision—swells from leaking fluid. This condition is called macular edema.
If new blood vessels grow on the surface of the retina, they can bleed into the eye and block vision. At first, you may see a few specks of blood, or spots, “floating” in your vision. If spots occur, see your eye care professional as soon as possible. You may need treatment before more serious bleeding occurs.
Sometimes, without treatment, the spots clear, and you will see better. However, bleeding can reoccur and cause severely blurred vision. You need to be examined by your eye care professional at the first sign of blurred vision, before more bleeding occurs.
If left untreated, proliferative retinopathy can cause severe vision loss and even blindness. Also, the earlier you receive treatment, the more likely treatment will be effective.
Dry eye occurs when the eye does not produce tears properly, or more commonly when the tears are not of the correct consistency and evaporate too quickly. Inflammation of the surface of the eye may occur along with dry eye. If left untreated, this condition can lead to pain, ulcers, or scars on the cornea, and some loss of vision. Permanent loss of vision from dry eye is uncommon.
Dry eye can make it more difficult to perform some activities, such as using a computer or reading. It can decrease tolerance for dry environments or enclosed areas.
Aqueous tear-deficient dry eye is a condition in which the tear glands do not produce enough tears to lubricate the eyes.
Evaporative dry eye may happen when the glands in the eyelids, that make the lipid or oily part of tears, slows evaporation and keeps the tears stable.
Some of the causes of dry eye include:
Dry eye can be managed as an ongoing condition. The first priority is to determine if a disease is the underlying cause of the dry eye. If so, then the underlying disease needs to be treated.
Cyclosporine, an anti-inflammatory medication, is the only prescription drug available to treat dry eye. It decreases corneal damage, increases tear production, and reduces symptoms of dry eye. In some cases of severe dry eye, short term use of corticosteroid eye drops that decrease inflammation is required.
If dry eye results from taking a medication, your doctor may recommend switching to a medication that does not cause the dry eye side effect.
If contact lens wear is the problem, your eye care practitioner may recommend another type of lens or reducing the number of hours you wear your lenses. In the case of severe dry eye, your eye care professional may advise you not to wear contact lenses at all.
Use of over-the-counter tears and gels offer temporary relief and provide an important replacement of naturally produced tears. Avoid artificial tears with preservatives if you need to apply them more than four times a day or preparations with chemicals that cause blood vessels to constrict.
Wearing glasses or sunglasses that fit close to the face (wraparound shades) or that have side shields can help slow tear evaporation from the eye surfaces. Indoors, an air cleaner to filter dust and other particles helps prevent dry eyes. A humidifier also may help by adding moisture to the air.
Avoid dry conditions and allow your eyes to rest when performing activities that require you to use your eyes for long periods of time. Instill lubricating eye drops while performing these tasks.
Glaucoma is an eye disease that damages the eye’s optic nerve. That’s the nerve that carries information from the eye to the brain. Left untreated, this disease can lead to vision loss and blindness. Often, you may not know you have glaucoma until it is very advanced. That’s why it is so important to have eye exams on a regular basis. Glaucoma can sometimes be caused by eye injuries or eye surgery. Even some medications such as corticosteroids can cause glaucoma.
There are six tests used to determine if you have glaucoma.
Most risk factors such as age, race and family medical history are out of the control of patients. We recommend having a dilated eye exam every 1 to 2 years, especially if you have a family history of glaucoma.
There is no restoring vision that is lost to glaucoma so the sooner you treat it the better.
Glaucoma treatments include medicines, laser trabeculoplasty, conventional surgery, or it could be a combination of any of these forms of treatment.
Macular degeneration, also known as age-related macular degeneration or AMD, is a condition where damage has occurred to the macula, a small spot near the center of the retina. The result is a blurry spot in the center of your field of vision. Over time, the blurry spot may grow larger or you may develop blank spots in your vision. AMD may not necessarily lead to total blindness, but it can affect or limit many activities such as driving, reading, writing, cooking or other types of close work. As you age, the macula can degenerate so that it is less effective in focusing images on your retina.
Wet AMD occurs when abnormal blood vessels behind the retina start to grow under the macula. These new blood vessels tend to be very fragile and often leak blood and fluid. The blood and fluid raise the macula from its normal place at the back of the eye. Damage to the macula occurs rapidly.
With wet AMD, loss of central vision can occur quickly. Wet AMD is also known as advanced AMD. It does not have stages like dry AMD.
An early symptom of wet AMD is that straight lines appear wavy. If you notice this condition or other changes to your vision, contact your eye care professional at once. You need a comprehensive dilated eye exam.
Dry AMD occurs when the light-sensitive cells in the macula slowly break down, gradually blurring central vision in the affected eye. As dry AMD gets worse, you may see a blurred spot in the center of your vision. Over time, as less of the macula functions, central vision is gradually lost in the affected eye.
The most common symptom of dry AMD is slightly blurred vision. You may have difficulty recognizing faces. You may need more light for reading and other tasks. Dry AMD generally affects both eyes, but vision can be lost in one eye while the other eye seems unaffected.
Smoking, race, age and family history are among the main causes of AMD. The disease is most likely to occur after the age of 60. Having a family history of AMD increases your risk and research has proven that smoking doubles your risk. AMD is also more common among Caucasians.

Neurotropic keratitis is a disease characterized by decreased corneal sensitivity which can lead to poor corneal healing. It is caused by the loss of sensory function to the ophthalmic portion of the trigeminal nerve, the nerve responsible for sensation and motor functions in the face like blinking and chewing.
This disorder leaves the cornea very susceptible to injury. It also decreases your eye’s natural function of tearing when you blink which can cause severe dry eye syndrome, corneal ulceration, scarring, and vision loss. Herpes zoster, Herpes simplex, and surgery on the trigeminal nerve are the most common etiologies of neurotrophic keratitis.
The ophthalmologists at VisionFirst Eye Center are board-certified and trained in the detection, management, and treatment of corneal diseases including neurotrophic keratitis.
