Diabetic Retinopathy

Diabetic retinopathy is a well-recognized complication of diabetes mellitus. Well-conducted clinical trials have shown that good control of diabetes and hypertension significantly reduces the risk for diabetic retinopathy, and there is evidence from studies spanning more than 30 years that treatment of established retinopathy can reduce the risk for visual loss by more than 90%. Once vision has been lost due to diabetic retinopathy, it usually cannot be restored, although some forms of retinopathy can be treated by complex vitreo-retinal surgery. Screening programmes for detecting diabetic retinopathy at a stage at which treatment can prevent visual loss and health education programmes are the mainstay of prevention of blindness due to diabetic retinopathy. Care for diabetic retinopathy is relatively expensive and requires properly trained eye-care professionals. The decisions made by each country are adapted to their resources, social expectations and available
health-care infrastructure. Effective services for prevention and treatment of diabetic retinopathy can be provided only if adequate medical services for patients with diabetes mellitus are in place.

Current situation
Diabetic retinopathy is responsible for 4.8% of the 37 million cases of blindness due to eye diseases throughout the world (i.e. 1.8 million persons). The proportion of blindness due to diabetic retinopathy ranges from close to 0% in most of Africa, to 3–7% in much of South-East Asia and the Western Pacific, to 15–17% in the wealthier regions of the Americas, Europe and the Western Pacific (6).

At least 171 million people worldwide have diabetes, and this figure is likely to more than double by the year 2030, to 366 million (33). About 50% of persons with diabetes are unaware that they have the condition, although about 2 million deaths every year are attributable to complications of diabetes.After 15 years, about 2% of persons with diabetes become blind, and about 10% develop severe visual loss. After 20 years, more than 75% of patients will have some form of diabetic retinopathy (34).

Overall, the direct health-care costs of diabetes range from 2.5% to 15% of annual health-care budgets, depending on the prevalence of diabetes and the sophistication of the services available. The costs of lost production can be as much as five times the direct health-care cost according to estimates derived from 25 Latin American countries (35, 36). In some countries, persons known to have diabetes are registered, so that screening programmes can be set up or the coverage of existing programmes be improved.

Childhood Blindness

As the causes of blindness in children differ from those in adults, different control measures are needed. In low-income countries, high proportions of children are blind due to preventable causes, which require community-based interventions. In all regions, children with treatable diseases, principally cataract, can have their sight restored. Childrens’ eyes cannot, however, be considered smaller versions of adults’ eyes, and specific expertise and equipment are required. Unlike adults, children require longterm follow-up after surgery, to manage complications and to prevent amblyopia (‘lazy eyes’). The understanding and involvement of parents is critical. In all regions, children with irreversible visual loss must be assessed for low-vision services, early visual stimulation, rehabilitation or special education, depending on their age and level of residual vision.

Current situation
It has been estimated that there are 1.4 million blind children in the world, 1 million of whom live in Asia and 300 000 in Africa (26). The prevalence ranges from 0.3/1000 children aged 0–15 years in affluent countries to 1.5/1000 children in very poor communities. Although the number of blind children is relatively low, they have a lifetime of blindness ahead, with an estimated 75 million blind-years (number blind × length of life), second only to cataract.

The same report showed that 500 000 children become blind each year (nearly one per minute). Many die in childhood from the underlying cause, such as measles, meningitis, rubella, prematurity, genetic diseases and head injuries. Most blind children are either born blind or become blind before their fifth birthday. Owing to demographic differences, the number of children who are blind per 10 million population varies from approximately 600 in affluent countries to approximately 6000 in very poor communities. About 40% of the causes of childhood blindness are preventable or treatable.

The causes of childhood blindness vary, but the main avoidable causes are:

  • corneal scarring in Africa and poorer countries in Asia;
  • cataract everywhere;
  • glaucoma everywhere;
  • retinopathy of prematurity in high- and middle-income countries and some cities in Asia;
  • refractive errors everywhere, but particularly in South-East Asia; and low vision, which encompasses visual impairment and blindness from untreatable causes, in all regions.

The main causes of blindness in children change over time. As a consequence of child survival programmes (for example, integrated management of childhood illness), corneal scarring due to measles and vitamin A deficiency is declining in many developing countries, so that the proportion due to cataract is increasing. Retinopathy of prematurity is emerging as an important cause in the middle-income countries of Latin America and eastern Europe and is likely to become an important cause in Asia over the next decade. The prevalence of refractive errors, particularly myopia, is increasing in school-age children, especially in South-East Asia.

Trachoma, which is the most common infectious cause of blindness, is caused by Chlamydia trachomatis. Children which have the active stages of the disease are the reservoir of infection, while blindness, which occurs after repeated episodes of infection, principally affects adults. Boys and girls are equally affected by active infection, while blindness is more common in women. Trachoma is a condition of poverty and is a focal disease, affecting communities that have poor water supplies and sanitation and poor health services. The organism is transmitted from person to person through direct and indirect contact and by flies. Blindness can be prevented by surgery to correct inturning of the upper eyelid(trichiasis),while the infection and its transmission can be reduced with surgery, antibiotics, facial cleanliness and environmental improvement (the SAFE strategy).

Current situation
Trachoma is endemic in 55 countries: Afghanistan, Algeria, Australia, Benin, Brazil, Burkina Faso, Cambodia, Cameroon, Central African Republic, Chad, China, Côte d’Ivoire, Djibouti, Egypt, Eritrea,Ethiopia, Fiji, Gambia, Ghana, Guatemala, Guinea, Guinea-Bissau, India, Islamic Republic of Iran, Iraq, Kenya, Kiribati, Lao People’s Democratic Republic, Libyan Arab Jamahiriya, Malawi, Mali, Mauritania,Mexico, Morocco, Mozambique, Myanmar, Namibia, Nepal, Niger, Nigeria, Oman, Pakistan, Papua New Guinea, Senegal, Solomon Islands, Somalia, Sudan, Togo, Uganda, United Republic of Tanzania, Vanuatu, Vietnam, Yemen, Zambia and Zimbabwe. The estimated number of affected people has dropped from 360 million in 1985 to about 80 million today. Trachoma affects the poorest and most remote rural areas of Africa, Asia, Central and South America, Australia and the Middle East (30). Updated reports on 36 countries are available (31), while 19 endemic countries have not yet reported data.

There are approximately 10.6 million people with inturned eyelashes (entropion trichiasis), for which eyelid surgery is needed to prevent blindness. The majority of these people are women. An estimated 8 million adults are irreversibly visually impaired from corneal scarring due to trachoma.


According to WHO definition: "Cataract is clouding of the lens of the eye which impedes the passage of light. Although most cases of cataract are related to the aging process, occasionally children can be born with the condition, or a cataract may develop after eye injuries, inflammation, and some other eye diseases."

Globally, cataract (opacification of the lens) is the single most important cause of blindness, and cataract surgery has been shown to be one of the most cost-effective health-care interventions. Most cataract is related to aging and cannot be prevented, but cataract surgery and insertion of an intraocular lens are highly effective, resulting in almost immediate visual rehabilitation. In well-managed eye units, high-quality, high-volume surgery is possible, one ophthalmologist being able to undertake 1000–2000 or more operations a year, as long as there are adequate support staff, infrastructure and patients who are able and willing to access the facilities.

Current situation
There are estimated to be almost 18 million people who are bilaterally blind from cataract, representing almost half of all causes of blindness due to eye diseases globally. The proportion of blindness due to cataract among all eye diseases ranges from 5% in western Europe, North America and the more affluent countries in the Western Pacific Region to 50% or more in poorer regions. The main non-modifiable risk factor is ageing. Other frequently associated risk factors are injury, certain eye diseases (e.g. uveitis), diabetes, ultraviolet irradiation and smoking. Cataract in children is due mainly to genetic disorders. Visually disabling cataract occurs far more frequently in developing countries than in industrialized countries, and women are at greater risk than men and are less likely to have access to services.

The cataract surgical rate—the number of cataract operations per million population per year—is a quantifiable measure of the delivery of cataract surgical services (Annex V). It is meaningful, however,only when it includes all cataract operations performed in a country, including those in the private sector and during outreach, and when the population size and age structure can be defined. Cataract surgical coverage indicates the number of individuals with bilateral cataract causing visual impairment, who have received cataract surgery on one or both eyes, in other words, the proportion who were eligible for surgery and who received it. This indicator is used to assess the degree to which cataract surgical services meet the need. The data are obtained from population-based surveys or rapid assessments. Software for monitoring and assessing the quality of cataract surgery is available, and VISION 2020 encourages the monitoring of quality so that performance continues to improve.

There are two main surgical techniques for removing a cataract: extracapsular cataract extraction and phacoemulsification. In extracapsular cataract extraction, the lens capsule is opened and the nucleus of the lens and the cortex are removed, leaving the posterior capsule in place. This can be done through a small incision, which does not usually require sutures, or through a standard incision closed by removable sutures. In phacoemulsification, an ultrasound probe is used to fragment the lens, which is aspirated through a small incision.

There are three ways of correcting aphakia, an eye with a surgically removed lens: spectacles, contact lenses or an intraocular lens. Thick spectacles are required for patients who have undergone intracapsular extraction, and this technique was widespread in the past. Contact lenses are not appropriate in most settings. An intraocular lens, implanted after the cataract has been removed, is the optimal method, as it makes the use of thick spectacles unnecessary. Nevertheless, light spectacles are often necessary to compensate the loss of accommodation.

World Health Oranisation Estimates

According to WHO estimates:

  • Approximately 285 million people worldwide live with serious vision impairment
  • Of these, 39 million people are blind and 246 million have moderate to severe visual impairment;
  • Also included, 153 million people are visually impaired due to uncorrected refractive errors (near-sightedness, far-sightedness or astigmatism). In most cases, normal vision could be restored with eyeglasses or contact lenses
  • Yet 75% of blindness is avoidable - i.e. treatable and/or preventable
  • 90% of blind people live in low-income countries
  • Restorations of sight, and blindness prevention strategies are among the most cost-effective interventions in health care
  • Infectious causes of blindness are decreasing as a result of public health interventions and socio-economic development. Blinding trachoma now affects fewer than 80 million people, compared to 360 million in 1985
  • Aging populations and lifestyle changes mean that chronic blinding conditions such as diabetic retinopathy are projected to rise exponentially
  • Women face a significantly greater risk of vision loss than men
  • Without effective, major intervention, the number of blind people worldwide has been projected to increase to 76 million by 2020

Know about Eye

Eyes are organs that detect light, and convert it to electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye is a complex optical l system which collects light from the surrounding environment; regulates its intensity through a diaphragm; focuses it through an adjustable assembly of lenses to form an image; converts this image into a set of electrical signals; and transmits these signals to the brain , through complex neural pathways that connect the eye, via the optic nerve, to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods

The simplest "eyes", such as those in microorganisms , do nothing but detect whether the surroundings are light or dark , which is sufficient for the entrainment of ciradian . From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment.
