Embodiment Construction

[0036] As shown in the accompanying drawings, for purposes of illustration, the present invention is directed to a course of treatment for treating the eye to stop or delay the onset or symptoms of retinal diseases, including chronic progressive retinal diseases, such as diabetic retinopathy ( DR) and age-related macular degeneration (AMD).

[0037] As discussed above, conventional thinking is that tissue damage and damage must be caused by retinal laser therapy to have a therapeutic effect. However, the inventors have found that this is not the case at all, and have shown that such thermal retinal damage is not necessary, and have questioned whether it confers the benefits of conventional laser therapy. The inventors have found that the therapeutic changes in cytokine production of retinal pigmented epithelial cells (RPE) elicited by conventional photocoagulation originate from cells at the margin of conventional laser burns that are affected but not killed by laser irradiati...

Abstract

A process for treating an eye to stop or delay the onset or symptoms of retinal diseases includes determining that the eye has a risk for a retinal disease before detectable retinal imaging abnormalities. A laser light beam is generated that provides preventative and protective treatment of the retinal tissue of the eye. At least a portion of the retinal tissue is exposed to the laser light beam without damaging the tissue. The retina may be retreated according to a set schedule or periodically according to the determination that the retina of the patient is to be retreated by monitored visual and / or retinal function or condition.

Description

technical field [0001] The present invention generally relates to phototherapy and photostimulation of biological tissue, such as laser retinal photocoagulation. More particularly, the present invention is directed to the procedure of treating the eye using harmless, subthreshold phototherapy or photostimulation to stop or delay the onset of symptoms of retinal disease in a patient. Background technique [0002] Complications of chronically progressive retinal diseases such as diabetic retinopathy (DR) and age-related macular degeneration (AMD) constitute a major cause of vision loss worldwide. Complications of diabetic retinopathy remain the leading cause of vision loss in people under the age of sixty. Diabetic macular edema is the most common cause of legal blindness in this patient population. Diabetes, the cause of diabetic retinopathy, and diabetic macular edema are increasing in incidence and prevalence worldwide, becoming prevalent not only in developed countries b...
