One of the most prevalent of the diabetes-related eye diseases is glaucoma. In fact, people with diabetes are between 40% and 50% more likely to develop glaucoma than non-diabetics.
Glaucoma causes the pressure within the eye to increase gradually, damaging the optic nerve and leading to partial or complete vision loss. The exact mechanisms for this are unknown. While there are several types of glaucoma, the most common form is open-angle glaucoma.
The eye is full of fluid which continually refreshes. Normally, fluid drains at a point in the eye where the iris and the cornea meet. If this opening becomes even partially blocked the fluid drains out of the eye too slowly, even as new fluid is added. This backup of fluid causes an increase in pressure within the eye, damaging the optic nerve.
Open-angle glaucoma does not cause any symptoms until the disease is well-advanced. By that time, vision is impacted, with loss of peripheral vision first, advancing to tunnel vision and then total vision loss as the disease progresses.
The goal of treatment is to lower intraocular pressure. This can be approached one of three ways: lower eye pressure, improve drainage of fluid from the eye or decrease the volume of fluid produced within the eye.
There are a variety of eye drops that may be prescribed.
Prostaglandins (xalatan, lumigan) and cholingeric agents (isopto carbine and isopto carbachol) act to increase outflow of fluid from within the eye.
Beta blockers (betimol, timoptic, betoptic) and carbonic anhydrase inhibitors (trusopt, azopt) reduce the production of fluid within the eye.
Alpha-adrenergic agonists (iopidine, alphagan) both lessen fluid production and increase fluid outflow.
Physicians may prescribe a combination of the above.
Oral medications may also be prescribed, if eye drops alone are not sufficient. These are usually in the form of a carbonic anhydrase inhibitor.
If medications are not sufficient to halt progression of the disease, then surgery might be necessary.
Drainage implants might be inserted within the eyes to facilitate drainage.
Laser surgery, known as laser trabeculoplasty, can be done to open clogged drainage canals.
Filtering surgery, known as trabeculectomy, removes a small piece of tissue from the location of the drainage canals, widening the opening and improving drainage.
The best possible treatment for glaucoma is prevention. Everyone above 40 years of age should have an eye exam at least every three years. Diabetics should have a dilated examination of their eyes annually.
Well-controlled blood sugar level are another preventive measure that will lessen the odds of developing glaucoma.

Sight is one of our most important senses. To ensure that your vision is not compromised, regular eye examinations are essential. This is regardless of age and overall health because the only way to diagnose conditions in the eye in the early stages is with a comprehensive eye exam. By arresting them in the early stages, many eye disorders can be easily controlled and treated.
During a routine eye examination, the doctor will look into a number of aspects of your eye's health. An eye examination can also indicate serious health issues like diabetes, macular degeneration and glaucoma. Some of the conditions an eye doctor looks for during an eye exam are:
- Refractive error: If you already have a prescription this will be checked. In other cases, the strength of the eye muscles is checked for near sightedness, far sightedness and astigmatism which can be corrected with lasik surgery, spectacles or lenses. The earlier a refractive error is corrected, the lower are its chances of increasing. When it comes to children, they often do not realize signs of vision deterioration and hence, an eye examination becomes essential.
- Amblyopia: This is a condition where one eye has a much higher refractive error than the other or where the eyes are misaligned. If this is not treated in time, amblyopia can stunt vision in the affected eye and result in blindness.
- Strabismus: Crossed or turned eyes are termed as cases of strabismus. This is caused by the misalignment of the eyes and can cause problems with depth perception. This can lead to amblyopia and eventual blindness if not treated in time.
- Focusing and communicative problems between the eyes: An eye examination can also determine problems with focusing on objects. With children this can be a sign of underdeveloped focusing skills while in adults it can be a symptom of presbyopia or age related diminished focusing ability. Your doctor will also check how well your eyes work together. If they do not work in tandem, it can cause headaches, eye strains and problems with reading.
- Diseases: By looking at the blood vessels and retina of the eyes, doctors can detect signs of high blood pressure, cholesterol etc. Leaks in the blood vessels or bleeding in the eyes can also be a sign of diabetes or swelling of the macula.
- Age related conditions: As with the rest of the body, the eye tissues and muscles also degenerate with time. Cataract is one of the most common age related issues that affect the eyes.
