If your eyes are itching, tearing, burning, or red you may have eye allergies, or what doctors call allergic conjunctivitis. Allergies develop when the body's immune system becomes sensitized to something such as pollen, dust, pet dander, or mold. These are called allergens, and there are many potential allergens in our environment that can come into contact with our eyes. With allergic conjunctivitis, allergens cause the eyes and surrounding tissues to become inflamed and uncomfortable. These symptoms may occur alone, or in combination with general allergic symptoms such as coughing, sneezing, or a stuffy nose. There are two main types of eye allergies: Seasonal and Chronic. Seasonal eye allergies are the most common form and occur in the spring or fall when the amount of pollen in the air is very high. Chronic eye allergies are less common, but potentially more severe than seasonal allergies. This form is non-seasonal and occurs continuously throughout the year. Chronic eye allergies may be triggered by dust, mold, pets or other allergens that are present year-round. While ocular allergies may be an ongoing condition, the right treatment from your eye care professional can reduce or eliminate symptoms.

Corneal refractive therapy (CRT) is a non-surgical treatment option for people suffering from mild to moderate presbyopia, nearsightedness, farsightedness, or astigmatism. CRT offers a legitimate alternative to laser vision correction for many people. This procedure uses specially designed contact lenses, which are prescribed to reshape the surface of the cornea and reduce or eliminate the need for glasses or regular contact lenses. CRT treatment involves changing the curvature of the cornea by temporarily molding its shape using a gas permeable contact lens.

Blepharitis is a common condition, that results in inflammation affecting the eyelids, and eyelashes. Symptoms of blepharitis include redness, irritation, crusting, and a dry or sandy feeling in the eyes and eyelids. In most cases, this condition does not cause damage to one's vision. Typical causes of this condition include bacterial infections, allergic reactions, excessive oil production by glands in the eyelid, or poor eyelid hygiene. If you are experiencing symptoms of Blepharitis, contact your eye care professional to schedule an eye examination.

Ocular surface diseases are disorders of the surface of the cornea, the transparent layer that forms the front of the eye. These diseases include dry eye syndrome, meibomian gland dysfunction, blepharitis, rosacea, allergies, scarring from glaucoma medications, chemical burns, and immunological conditions. Ocular surface diseases can severely affect eyesight and quality of life. Symptoms may include blurry vision, discomfort or pain, redness and itching, and in severe cases, blindness due to corneal scarring. Unfortunately, cases often go undiagnosed and untreated due to a lack of understanding of symptoms and inaccurate evaluation.

When we are young, the lens inside of our eye is extremely flexible, and allows us to easily focus on close objects. Over time, the lens gradually loses its flexibility, which makes it difficult to focus on close objects. This condition is called Presbyopia, and it is a normal part of the aging process that happens to everyone, even those who have never had a vision problem before.

In a healthy eye, a balance exists between the fluid produced, and the fluid that leaves the eye. This balance keeps the eye pressure at a healthy level. In order to maintain balance the eye has a built-in drainage system. This drainage system controls the inflow and outflow of fluids, which is responsible for nourishing the eye. The eye's drainage system works a lot like a sink. Fluid is produced from the faucet and exits through the drain. If a blockage develops in the eye's drainage system, or if fluid is produced faster than it can escape - an overflow will occur. In the eye, this overflow causes the pressure to elevate. The optic nerve is most vulnerable to damage from elevated pressure. Continuous elevated pressure or spikes in pressure can damage the optic nerve. If left untreated, damage to the optic nerve can lead to vision loss and even blindness. The main goals of glaucoma surgery are to reduce eye pressure and prevent vision loss. When treating glaucoma one option to reduce pressure, is to turn off the faucet. Another option to reduce pressure is to remove the blockage that's slowing the fluid from escaping. And the final option for reducing pressure is to create a new channel for the fluid to escape through. Your doctor will recommend the best option for you.

Healthy tears consist of a precise mixture of oil, water, and mucus. Meibomian gland dysfunction, also called MGD, is a condition where the meibomian glands do not produce the proper quality or quantity of oil in the outer layer of the tear film. In normal tears, the layer of oil produced by the meibomian glands seals the tear film and helps prevent tears from evaporating too quickly. In MGD, the glands become blocked and do not produce normal oil, due to inflammation. Inflammation can be related to problems of the lid, contact lenses, hormones, or even incomplete or infrequent blinking. When the glands do not produce enough quality oil, tears evaporate more quickly than normal, resulting in dry eye syndrome. MGD is the leading cause of dry eye. While MGD is not generally sight-threatening, it can have a negative impact on quality of life if left untreated. Symptoms of MGD can include dryness, scratchiness, a burning sensation and even problems with visual acuity. MGD can also lead to chalazia and infections of the lid margins, which can be painful and unsightly for patients. Lastly, for patients who wear contact lenses, MGD can make wearing lenses very difficult. MGD does not usually go away on its own, and requires treatment and follow up examinations by an eye care professional.
