North Texas Eye Care Disease Management

Glaucoma

Glaucoma is the name given to a group of optic nerve conditions which are characterized by a raised intraocular pressure. This is usually associated with typical changes to the optic disc and in the visual field, but identical changes can ocassionally be seen in patients whose intraocular pressure has never been raised (low-tension glaucoma). It has been estimated that approximately three hundred people per one hundred thousand suffer from glaucoma; the prevalence increases with age and, in some studies, glaucoma has been shown to affect one percent of the population over forty years of age.

Retina Related

The vitreous cavity is the space within the eye bounded anteriorly by the lens and its zonular fibres. Its volume is usually about 4mls, though this may increase to as much as 10mls in highly myopic eyes. Normally the space is entirely occupied by vitreous gel, a virtually acellular viscous fluid with a ninety-nine percent water content. Many common retina related occurences can include retinal detachment, peripheral retinal degeneration, or common flashes and floaters.

Macular Degeneration

Proper functioning of the macula is essential for normal visual acuity and many patients with retinal disease only present when the macula is involved and central vision is disturbed. Central distortion of the visual image or minification are pathognomonic for macular disease. Closer questioning may reveal symptoms of photophobia, glare or dazzle, poor color perception and a central or paracentral scotoma. Clinically, it is useful in the differential diagnosis and classification of macular lesions to localize the primary defect to the correct anatomical layer. Investigation of macular disease requires careful refraction and assessment of acuity for distance and near vision. Fundus photography (Optos), visual field, and macular ocular coherence tomography (Macular OCT) are essential in the diagnosis and documentation of the macula. Apart from the use of low visual aids, no treatment is available for the vast majority of retinal dystophies and degenerations. In the management of the patient, perhaps the most important factor is to be able to give a diagnosis, visual prognosis, and genetic and occupational counselling where required. It is unusual for any degenerative macular disease to progress to total blindness and in most cases patients have a central scotoma with good peripheral vision and can lead independent lives.

Dry Eye Syndrome

Dry Eye Syndrome affects more than 60% of the United States population. If your eyes are constantly dry, or if you are a contact lens wearer, or you notice sudden loss of vision, at North Texas Eye care we can design a plan of care to increase moisture in the eyes.

Trauma

Whether you have irritated/scratchy eyes, red eyes, severe pain, blunt trauma, or serious injury, at North Texas Eye Care we can diagnose you present illness and design a plan of care that will suite your needs.

Keratoconus

Keratoconus is a condition in which the normally round shape of the cornea is distorted and a cone-like shape is created. This creates severe visual impairment. This condition normally begins in a patient's late teens or early twenties and goes through a progression that can last five to twenty years. As the keratoconus progress, then cornea becomes thinner and becomes irregular, and can form corneal scars.
