macular edema following diabetic retinopathy is one of the ocular complications associated with diabetes, and it is the leading cause of visual loss in the active young and middle aged population in developed countries. while all patients with diabetes particularly those with diabetic retinopathy are at increased risk of developing eye complications, early detection and timely intervention may ...
Introduction Currently, three types of therapy are approved for the treatment of exudative age-related macular degeneration (AMD): laser photocoagulation, photodynamic therapy with Verteporfin and intravitreal injections of antiangiogenic agents (Ranibizumab and Pegaptanib). Other treatments revealed to be ineffective or even more aggressive than natural disease progression. Examples of these l...

SUMMARY laser operate on the principle that excited atoms can be stimulated to emit photons, Resulting in a Markedly amplified light that possesses the Unique properties of coherence, Monochromacy and high Intensity. The Nature of this light allows precise alteration of tissues, primarily by photocoagulation and disruption which has been Utilized in several forms of surgery.
THE photocoagulating beam was studied in the first article of this series. This second article is devoted to the observation system, the essential requirement of which is proper illumination of the fundus. Taking into account that the coagulating beam is already directed towards the patient's eye, it seems obvious that it should also be used for illuminating the fundus. In fact, this has been t...
OBJECTIVES To evaluate the long-term natural history and effects of laser photocoagulation treatment in patients with diabetic retinopathy. DESIGN Follow-up study of the 214 surviving patients enrolled originally at the Johns Hopkins Clinical Center for the Early Treatment Diabetic Retinopathy Study (ETDRS), which was a clinical trial designed to evaluate the role of laser photocoagulation an...
PURPOSE To analyze the influence of age on retinochoroidal wound healing processes and on glial growth factor and cytokine mRNA expression profiles observed after argon laser photocoagulation. METHODS A cellular and morphometric study was performed that used 44 C57Bl/6J mice: 4-week-old mice (group I, n=8), 6-week-old mice (group II, n=8), 10-12-week-old mice (group III, n=14), and 1-year-old...
