We Can Help You Adjust to Changes in
Your Vision

Low vision is a condition that describes when your vision is reduced to a point where glasses, contact lenses, or surgery can no longer help correct it. The World Health Organization classifies severe low vision as when vision with the best possible eyeglass prescription is 20/200 or worse.

Although it may take some lifestyle adjustments and support from your loved ones, most individuals with low vision continue to lead fulfilling and engaging lives. At Optical Illusions: An Optometric Practice, we’ll work with you to develop a plan that helps you live comfortably.

What Causes
Low Vision?


Low vision can be caused and progressed by different health-related issues and various eye diseases.

Age-Related Macular Degeneration

Age-related macular degeneration, or AMD, is a degenerative condition that affects the retina. The retina is the light-sensitive lining at the back of the eye where light focuses to create the images we see. With AMD, the central-most part of the retina, called the macula, begins to deteriorate and cause blurred vision.

AMD can progress to a point where central vision is completely blocked, making it the leading cause of severe vision loss in people over 50.

Glaucoma affects the optic nerve, which carries information from the visual system to the brain, and is often asymptomatic until vision loss begins to occur. The most common type of glaucoma occurs when the eye’s fluid cannot drain properly, causing internal eye pressure to rise. The elevated intraocular pressure puts stress on the optic nerve and subsequently damages it.

If diagnosed and treated early, vision loss related to glaucoma can often be minimized. However, if the condition is allowed to progress, severe vision loss can occur.

Uncontrolled diabetes can lead to various changes to the eye including cataracts and diabetic retinopathy. Diabetic Retinopathy is quantified by the amount of microaneurysms, dot/blot hemorrhages, cotton wool spots, exudates, and macular edema in the retina. There are five stages, starting from mild, moderate, severe, very severe, and proliferative diabetic retinopathy as the end stage.

Blood sugar control, medication compliance, and regular visits with primary care physician are the best ways to prevent the occurrence of diabetic retinopathy.

Retinal detachment is a sight threatening condition with an incidence of approximately 1 in 10000.

Risk Factors for Retinal detachment:

  • Retinal Detachment
  • Lattice degeneration
  • Peripheral retinal breaks
  • Pathologic myopia
  • Previous intraocular surgery
  • Trauma
  • Previous retinal detachment
  • Family history

Patients with known risk factors for retinal detachment should have dilated fundus examinations yearly. Protective eyewear is recommended for individuals with high myopia that participate in contact sports.
