Embodiment Construction

[0046] The present invention relates to systems and methods for treating retinal diseases, including vascular retinal diseases such as diabetic retinopathy and diabetic macular edema, by producing predetermined parameters of harmless, true subthreshold photocoagulation. Contrary to conventional thinking and practice, the inventors have found that retinal laser therapy does not cause any laser-induced retinal damage, but can be at least as effective as conventional retinal photocoagulation.

[0047] Conventional thinking assumes that physicians must intentionally create retinal damage as a prerequisite for therapeutically effective treatment. Referring to Figure 2, Figures 2A-2D are graphical representations of the effective surface area of ​​various retinal laser treatment modalities for retinal vascular disease. The gray background represents retina 18 unaffected by laser treatment. Black areas 24 are areas of the retina that have been damaged by conventional laser technique...

Abstract

A process for performing retinal phototherapy or photostimulation includes generating a laser light that creates a therapeutic effect to retinal and / or foveal tissues exposed to the laser light without destroying or permanently damaging the retinal or foveal tissue. The laser light is applied to a first treatment area of the retina. After a predetermined interval of time, within a single treatmentsession, the laser light is reapplied to the first treatment area of the retina. During the interval of time between the laser light applications to the first treatment area, the laser light is applied to one or more additional areas of the retina that is spaced apart from the first treatment area and one another. The laser light is repeatedly applied to each of the areas to be treated until a predetermined number of laser light applications to each area to be treated has been achieved.

Description

Background technique [0001] The present invention generally relates to phototherapy or photostimulation of biological tissue, such as laser retinal photocoagulation. More specifically, the present invention relates to systems and methods for treating retinal diseases and disorders through the use of innocuous, subthreshold phototherapy or photostimulation of the retina. [0002] Complications of diabetic retinopathy remain the leading cause of vision loss in people under the age of sixty. Diabetic macular edema was the most common cause of legal blindness in this patient group. Diabetes is the cause of diabetic retinopathy and thus diabetic macular edema is increasing in incidence and prevalence worldwide and becoming prevalent not only in developed countries but also in developing countries. Diabetic retinopathy may begin to appear in people with type I (insulin-dependent) diabetes within three to five years of disease onset. The prevalence of diabetic retinopathy increase...
