Diabetic Retinopathy - Essay ExampleResults from numerous clinical campaigns of laser photocoagulation and various other treatments and a well(p) understanding of the pathogenesis would have a huge impact on blindness in the diabetic population. PubMed - indexed for MEDLINEThe prevalence of retinopathy is strongly linked to the duration of diabetes. A stringent control of blood stops levels delays the onset of diabetes. Vision loss with diabetic retinopathy may occur from several different mechanisms such as Macular oedema or ischemia which may misdirect central vision.Extensive studies have reported the cost effectiveness of screening for diabetic retinopathy as it saves vision at reduced costs. The cost of screening modalities depends generally on various factors such as trained professionals and accessibility of screening equipment.Current management of diabetic retinopathy includes systematic control of blood pressure and glucose levels, surgical process including laser pho tocoagulation or pars plana vitrectomy and currently developed pharmacologic interventions. Vitrectomy is capable of restoring utilitarian vision to patients suffering from severe diabetic retinopathy and vitreous hemorrhage either with or without an accompanying traction retinal detachment. PubMed - indexed for MEDLINESystemic ControlDevelopment and progression of diabetic retinopathyis delayed by glycemic control. Laser photocoagulation, which represents the only treatment modality in large, controlled, prospective randomized, clinical trials, shows limited efficacy. Currently, new pharmacologic modalities now being evaluated show promise, but should undergo rigorous prospective randomized clinical trial in order to gain widespread acceptance. Intensive therapy brought down the risk of developing diabetic retinopathy by 76% and reduced the risk of progression of already existing retinopathy by 54%. Maintaining a strict and systematic control of blood pressure and glucose has prove n to be difficult for many patients with diabetes. A good number of them will still develop progressive retinopathy and would require either vitrectomy or laser photocoagulation PubMed - indexed for MEDLINESurgeryThe latest in surgical techniques is the use of the metre Electron Avalanche Knife (PEAK-fc, Carl Zeiss Meditec, Jena, Germany) (British Journal of Ophthalmology 200791949-954) which is a new pulsed electrosurgical device that helps in the precise cold traction- free tissue dissection. It is very useful in all complicated eye surgeries.For late stages of retinopathy, current laser or surgical treatments are applicable. It also includes proliferative diabetic retinopathy or sight-threatening ME. The study that was conducted be that photocoagulation can reduce the risk of severe visual loss by about 50%. PubMed - indexed for MEDLINEIn this process, laser photocoagulation leads to decreased oxygen levels by the retina due to the decease of the photoreceptor.Anakinra, which is a drug used in arthritis has tested favorably for reducing blood sugar levels. Benfotiamine is a fat-soluble form of vitamin B1 has proved effective by reversing the defile done to the retina due to high blood sugar in the cells. Another surgical research is the
