Ocular Disease



We provide diagnosis, treatment and management of diseases which affect the human eye and visual system.  Some examples include:


Diabetic Retinopathy  is a condition when a diabetic persons blood sugar is not controlled well and the increased sugar levels start a series of events which end in damaged blood vessel walls.  The blood vessels begin to leak fluid or bleed, causing the retina to swell and form deposits know as exudates.  Vision can be lost if these spots are not watched and treated.  Dr. Valella carefully examines the back of your eyes to follow and manage this and many other important eye diseases.



Macular Degeneration is a condition in which the central part of the back of the eye loses blood circulation.  For most, it is considered a natural aging process.  There is a breakdown of retinal pigment epithelium cells in the macular region.  As the disease progresses, central vision diminishes.  It is believed that this breakdown may be due to a lack of nutrients being supplied to the region. Additional studies have found a genetic link to this disease.  Treatment can range from better nutritional management, sometimes to include a tablet containing the primary minerals and vitamins that are found lacking in many macular degenerated patients.  New treatment for both the wet and dry forms of the disease are being developed.


Cataract is a clouding or opacity of the natural internal lens of the eye.  This opacity may be a small spot or may include the entire lens.  When light enters an eye with a cataract, it is scattered, causing images to appear hazy and blurred.  There are many different types of cataracts.  The one shown here is a cortical cataract.  Here the opacity forms first in the periphery of the lens and develops inward, like spokes of a wheel.  Ultimately, the best  treatment if a cataract is causing significant vision loss is to remove the cataract lens and replace it with an acrylic man made lens.  This is referred to as cataract surgery. Dr. Valella works closely with her cataract surgeons to help her patients achieve the best surgical outcomes possible.



Dry Eye Syndrome  occurs when the normal flow of tears over the eyes is interrupted, or the tear film is abnormal.  In many cases, dry eye syndrome is a life long problem.  You can relieve the symptoms, but not cure the original cause.  Artificial tear lubricants, prescription drugs and/or in some cases blocking the tear ducts will concentrate the limited tears that are available. Dr. Valella provides all these services.
