Retinal Detachment
The majority of retinal detachments are rhegmatogenous in origin, that is they are caused by a break in the retinal neuroepithelium. Others reflect the development of static traction forces within the vitreous gel, along the detached posterior hyaloid membrane or on the retinal surface. Two other broad groups of retinal detachments are recongnized as solid detachments and serous detachments. Retinal detachments must also be distinguished from other disturbances in the coats of the eye which may simulate detachment of the retina. Common signs and symptoms of retinal detachment are flashes of light, appearance of floaters, a cloud over a certain area of your vision, loss of vision, and/or blood distorted vision. If you notice any of these symptoms, please call the emergency contact number to rule out a retinal detachment.

Infantile retinoschisis is a rare disorder with a sex-linked mode of inheritance; it's therefore affects young males. A common presentation is vitreous hemorrhage, while central vision may be impaired by associated foveal schisis. Progression to a retinal detachment is unusual. After middle-age, bilateral retinoschises are frequently discover during routine examination of the peripheral fundus, and tend to be located inferotemporally. The outer leaf of the schisis often has a grey translucency with a mottled pattern. Retinoschisis should be monitored to show that no progression has occured.

Diabetic Retinopathy
Background retiinopathy is the most common form of diabetic retinopathy. Breakdown of the blood-retinal barrier has already occured by the time opthalmoscopic changes are visible, either as a result of changes in the barriers of the retinal circulation or the retinal pigment epithelium. At first, background retinopathy is normally most prominent in the retina temporal to the macula, probably because this is a watershed area in the retinal circulation. Maculopathy is the most common cause of legal blindness from diabetic retinopathy. Proliferative diabetic retinopathy tends to occur in diabetics who have evidence of severe involvement of other systems and these patients generally carry a poorer prognosis for life. A life expectancy, on average, of less than six years after the onset of the retinal neovascularization is often quoted but this is improving with better medical treatment. The importance of monitoring is essential.

Visit 1: Retinal Imaging, Visual Field Testing, and Dialation
Visit 2: Macula OCT, VEP, pERG, and Color Testing (if needed)
