The neural network method is suitable for solving pattern recognition problems such as lesion patterns of various stages of severity of DR; thus the neural network method is helpful in grading DR. In the early stages of non-proliferative diabetic retinopathy, treatment may not be needed but regular comprehensive dilated eye exams or more often as recommended by the eye doctor are important for monitoring the disease.
Cost-effectiveness of detecting and treating diabetic retinopathy. The TV values for retinopathic eyes are significantly high when compared to the TV values for the healthy eyes. ETDRS report number 9. Even though there are several screening methods to detect diabetic retinopathy, debate prevails on how this screening is done.

Any community willing to invest in diabetic eye screening can expect the number of legally blind diabetic patients to decrease by twofold to threefold within 10 years and decrease the disability expenditures by an amount that is many times the initial investment.
The pattern recognition consists of two distinct methods: Blindness caused by diabetic retinopathy. Department of Health and Social Security. Patients with STDR grades R2, R3, maculopathy, and ungradable are referred to specialist ophthalmology clinics of the Hospital Authority for further management.
Sustainability of a quality-assured screening programme, ensuring that patients are compliant with appropriate screening intervals and treatment, is one of the greatest challenges that can be overcome by educating the population and empowering primary eye care workers and health care workers.
The major cause for this disease is uncontrolled diabetics [ 9 ]. Total Variation [ 13 ] is a common method used in digital image processing.
Screening for Diabetic Retinopathy Ophthalmoscopy [ 6 ] is a well-known screening technique for diabetic retinopathy. Epub ahead of print. This helps the doctor monitor the disease and determine the best treatment options. In the group of patients who developed mild retinopathy, 38 had type 1 diabetes, and 58 had type 2.
Two-field photography has the advantage of detecting DR in the nasal retina that could otherwise have been missed by single-field photography. For the patients who did not develop retinopathy during the entire period, there were 46 type 1 patients with diabetes and type 2.
American Journal of Ophthalmology. A considerable research effort is being made in diabetic eye disease. Two-field photography has the advantage of detecting DR in the nasal retina that could otherwise have been missed by single-field photography. Patients with a longer duration and higher HbA1c are also found more frequently in the groups with a higher grade of retinopathy.
Grader requirements and quality assurance The graders undergo a structured training programme to identify different features of DR, periodic assessments, and continuous monitoring of grading performance.
For this reason, mydriatic fundus photography is preferred in the diabetic population given that cataract is more prevalent as it has the advantage of having a lower percentage of ungradable images due to media opacity. Jerneld B, Algvere P.
Possible new method to improve detection of diabetic retinopathy: But what is the value of detecting diabetic change in the retina at this early stage? Ophthalmoscopy is one of the screening methods that can be used to detect the disease at an early stage.
The present study is carried upon images obtained from fundus photography screening have been used for an automatic detection of diabetic retinopathy. Understanding Keywords Diabetic retinopathy, screening, ophthalmoscope, fundus images, total variation, HRF dataset Introduction Human eye is a fundamental sense organ that enables vision.
The aim of this paper was to review the methods of screening for DR from both a global and local perspective. Opportunistic screening may not be checked for quality assurance and may not include all those at risk.
The detection ability of colour fundus photography using a fundus camera to detect DR was compared with that of doctors in diabetic clinics using ophthalmoscopy.

Department of Health and Social Security. Br J Ophthalmol —Diabetic eye disease is a major cause of blindness in the Western World and remains one of the most serious complications of diabetes mellitus.
Retinopathy is the ocular complication of diabetes that most often leads to impaired vision. In recent years laser treatment has been introduced that can.
Diabetes mellitus causes both macrovascular complications such as coronary artery disease, peripheral arterial disease, and stroke; and microvascular complications such as diabetic nephropathy, neuropathy, and retinopathy.5 Diabetic retinopathy (DR) is one of the most common microvascular complications and one of the most common causes.
Prevalence of diabetic retinopathy in Norway: report from a screening study. Purpose: The purpose of the present study was to investigate the prevalence of diabetic retinopathy (DR) Screening and prevention of blindness. A doctoral thesis.
CONCLUSION: Diabetic retinopathy is the leading cause of blindness among persons of working age in the industrialized world. Regular ophthalmological examinations, timely laser therapy depending on the stage of the disease, and close interdisciplinary cooperation are essential to prevent loss of vision.
