Retina edema causes, Retinopátia | Egészséges étel a közelemben
Luigi Sacco University Hospital Rövid összefoglaló Macular edema is the most important cause of visual impairment in diabetic patients. Intravitreal injections of antiVEGF vascular endothelial growth factor agents and laser treatment are two effective therapies for stabilising visual acuity. However, antiVEGF therapy is very expensive and potentially needs to to be repeated for all patients life.
Laser treatment, according to modified ETDRS early treatment diabetic retinopathy studyproduces retinal burns with possible negative consequences such as alterations in the visual fields. In this way the amount of energy delivered to the retina and retinal pigment epithelium RPE is significantly reduced. This finer control of the photothermal effects retina edema causes avoid any retinal and RPE damage.
At the same time, according to several published reports, the efficacy of treatment appears to be equivalent to conventional laser therapy. Previous studies investigated the effects of nm micropulse laser therapy.

Recently, this treatment modality has been made available also with nm wavelength, which corresponds to the maximum absorption level for blood. Aim of this study is to assess the safety and efficacy of nm micropulse laser treatment compared to conventional modified ETDRS laser therapy. Átfogó állapot.
