Vision, Eye Diseases and Visual Impairment

SCIENTIFIC WORK

According to forecasts, in the next decades, the global need for ophthalmic care will increase sharply, which creates a serious problem for health care systems. Despite coordinated actions during the last 30 years, significant problems still remain. The World Report on Vision Problems is intended to stimulate countries' actions to solve these problems, offering comprehensive ophthalmological care (IPEC) oriented to people's needs as an approach to strengthening the health care system, which serves as the basis for providing services that meet the needs of the population.

A newborn needs sight to recognize and connect with her mother, a toddler to balance and walk, a schoolchild to go to school, read and learn, a young woman to participate in work activities, an older woman to maintain her independence. Eye diseases are extremely common. Everyone has it a person who has lived to old age has at least one vision problem. Globally, at least 2.2 billion people live with some form of visual impairment or blindness, and of these, at least 1 billion people have preventable or reversible visual impairment. However, planning requires more reliable data on met and unmet eye care needs. In addition, the prevalence of eye diseases and visual impairment is uneven. In general, the prevalence of these diseases is higher in low and middle-income countries and among populations that underserved, such as women, migrants, indigenous people, people with certain disabilities, and rural communities. In the coming decades, the growth and aging of the population, changes in behavior and lifestyle, and urbanization will lead to a sharp increase in the number of people with eye diseases, visual impairment and blindness (Desrosiers, Wanet-Defalque, Temisjian, Gresset, Dubois, Renaud, 2009: 1227-34). In a global society built on the ability to see, vision plays a crucial role in every aspect and at every stage of life. Of the five human senses, sight is the key and plays a crucial role in all aspects of our lives. Vision is an integral part of interpersonal and social interactions in person, when information is conveyed through non-verbal cues such as gestures and facial expressions (Heine, Browning, 2002: 763-73). From the moment a child is born, vision is critical for its development. For babies visual recognition and responses to parents, family members and caregivers care, promotes cognitive and social development and improvement of motor skills, coordination and balance (Warren,1994). From early childhood to adolescence, vision provides free access to educational materials and plays a key role in education (Ethan, Basch, 2008: 411-6; Toledo, Paiva, Camilo, Maior, Leite, Guerra, 2010: 415-9). Vision helps develop social skills to strengthen friendships, self-esteem and well-being (Rainey, Elsman, van Nispen, van Leeuwen, van Rens, 2016: 2633-43). Vision is also important for participation in sports and social activities, which are essential for physical development, mental and physical health, personal integrity and socialization (Oh, Ozturk, Kozub, 2004: 39). In adulthood, vision ensures participation in labor activities, contributing to the receipt of economic benefits and maintaining self-esteem (Nyman, Gosney, Victor, 2010: 1427-31). Vision also allows you to enjoy many other areas of life that are based on the ability to see, such as sports or cultural activities. In later life, vision helps maintain social contact and independence, and facilitates the treatment of other diseases. Vision also helps support mental health and well-being, which are higher in people with good vision (La Grow, Daye, 2005). Although not all eye diseases result in to visual impairment, often such diseases are accompanied by personal and financial difficulties. Eye diseases cover a wide and varied range of diseases that have a negative impact on the various components of the visual system and the visual 84 ELMİ İŞ Beynəlxalq elmi jurnal.

One way to classify is to distinguish between diseases that are not usually associated with visual impairment and those that do so (Tables 1.1). Table 1.1 The most common eye diseases that do not usually lead to visual impairment Blepharitis-Inflammation of the eyelids at the base of the eyelashes,characterized by redness and irritation of the eyes and eyelids. Chalazion and hordeolum (barley) Common inflammatory diseases of the eyelids, caused by obstruction of the outlet channel of the gland or local infection, which may be accompanied by pain Conjunctivitis inflammation of the conjunctiva (the clear membrane that covers the inside of the eyelids and the white part of the eye), most commonly caused by an allergy or infection. Dry eye syndrome a pathological condition characterized by insufficient production of tear fluid, which can lead to irritation and blurred vision. 85 ELMİ İŞ Beynəlxalq elmi jurnal.

In advanced cases, pterygium can affect the cornea and lead to vision loss. Subconjunctival hemorrhage The accumulation of blood in the space between the sclera and the conjunctiva due to damage to the blood vessels. Table 1.2 Most common eye conditions that can lead to visual impairment, including blindness Age-related macular degeneration damage to the central part of the retina for detailed vision, leads to the appearance of dark spots, shadows or distortion of central vision. The risk of developing macular degeneration increases with age. 86 ELMİ İŞ Beynəlxalq elmi jurnal.

Cloudy of the cornea A number of conditions that cause corneal scarring or clouding. Cloudiness is most commonly associated with trauma, infection, or vitamin A deficiency in children. Diabetic retinopathy Damage to the blood vessels in the retina, resulting in increased permeability or blockage of the vessels. Loss of vision most often occurs due to swelling in the central part of the retina, which can lead to visual impairment. Abnormal growth of blood vessels also occurs in the retina, which can cause hemorrhage or scarring of the retina and blindness. 87 ISSN: 2663-4619 e-ISSN: 2708-986X ELMİ İŞ Beynəlxalq elmi jurnal.

Refractive anomalies A group of diseases in which a decrease in visual acuity due to a violation of the focus of the image on the retina due to the irregular shape or length of the eyeball. There are several types of refractive errors - The most frequently mentioned in the report are: Myopia is a difficulty in seeing distant objects (myopia). Presbyopia - difficulty seeing objects located at close range, progressive with age (i.e. after 40 years). Trachoma An eye disease caused by a bacterial infection. If the infection recurs over many years, the eyelashes can turn inward (called trichiasis), which can lead to scarring of the cornea and, in some cases, blindness. 88 ISSN: 2663-4619 e-ISSN: 2708-986X ELMİ İŞ Beynəlxalq elmi jurnal.

Many eye diseases are multifactorial in nature. Conclusion Many factors influence the risk of developing or progressing these diseases. These include aging, lifestyle and behaviour, infections and a number of other diseases. Aging is a major risk factor for many eye diseases. With age, the prevalence of presbyopia, cataracts, glaucoma, and agerelated macular degeneration increases dramatically (Brown, Barrett, 2011: 364-73). Genetics also play a role in the development of several eye diseases, including glaucoma, refractive errors, and retinal degenerative changes such as retinitis pigmentosa. Ethnicity is an example of a nonmodifiable risk factor development of certain eye diseases. Lifestyle or behavior is also associated with many eye diseases. Smoking is a major modifiable risk factor for age-related macular degeneration (Fitzgerald, Parkes, 1998: 1160-3) and plays a role in the development of cataracts (Wang, Mitchell, Smith, 2000: 49-54). Diet can also play an important role in the development of eye diseases. For example, vitamin A deficiency as a result of chronic malnutrition in children can cause corneal clouding. In addition, certain occupational and leisure activities, such as agricultural or mining work and contact sports, are associated with an increased risk of eye injury. References 1.
