Good vision is not just the result of healthy eyes; it also depends on an healthy link between the eyes and the vision centers of the brain. The Eye Institute provides services for diagnosing and treating diseases that affect anatomical structures behind the eyes, which can cause symptoms such as blurred vision, double vision, asymmetrical pupils, eyelid or facial contractures, eye or head pain and unexplained vision loss.

  Orbital and Oculoplastic Surgery

The structures that support and protect the eye — the eyelids, the eye socket, the muscles that move the eyes, the soft tissues that surround the eyes and the tear system that helps keep the eyes moist — all can be affected by injuries, infections, inflammations, tumors, congenital anomalies and problems related to aging. The oculoplastic surgeons at the Eye Institute combine in-depth knowledge of the eye with expertise in reconstructive surgery to treat a broad range of conditions: eyelid abnormalities, eye socket injuries, tear system disorders and facial muscle issues.

Some of these ophthalmologists also treat adult strabismus, which is defined as misalignment of the eyes. It is commonly termed wandering eye, crossed eye or lazy eye.

  Refractive Surgery/LASIK

Many people who suffer from nearsightedness (myopia), farsightedness (hyperopia) or astigmatism are able to reduce or eliminate their dependence on glasses or contact lenses by undergoing refractive surgery, including LASIK.

  Retina and Vitreous

The retina is the inner posterior lining of the eye that contains the photoreceptor nerve cells that give us vision. The vitreous is a jelly-like substance that fills the middle eye. When a person is experiencing retina or vitreous problems, they may notice floaters and flashes, decreased vision, blurred or distorted vision or they may have no symptoms at all. The retina faculty physicians and staff at the Eye Institute are committed to providing innovative, specialized diagnosis and treatment of diseases and disorders affecting the retina, vitreous and macula.

Uveitis generally describes a group of inflammatory diseases that produces swelling and destroys eye tissues. Although often affecting a part of the eye called the uvea (hence the term “uveitis”), uveitis can also affect the lens, retina, optic nerve and vitreous. Symptoms of uveitis include pain, light sensitivity, blurred vision, floaters and redness of the eye. Uveitis can affect people of all ages and affect one or both eyes. Causes include trauma, autoimmune diseases, by other diseases affecting the body or infections from viruses, fungus or parasites.
