Oneof the most familiar eye problems of the elderly is thepresence of cataracts.Cataracts come about due to changes in the eye lenses making themless transparent. The changes may prevent the penetration of light tothe retina thus, leading to cloudy or misty vision. The modificationof the lens’ composition and structure of the lenses occur due tochanges in the proteins that constitute the lenses (Ball,Dains, Flynn, Solomon, & Stewart,2015). The clumps of protein on, or in the lens are responsible forthe blurry vision experienced by individuals with cataracts.
Maculardegenerationinvolves the deterioration of the eye’s macula. The macula is asmall region of the retina that has a greater sensitivity to detailsthan the entire retina. The macular degeneration process involves theformation of drusen below the retina, and the growth of unusual formsof blood vessels under the retina. The thinning and ageing of themacular tissues are also known to cause macular degeneration. Theabnormalities in the tissue in turn affect the vision, and may leadto loss of vision. Macular degeneration can also start on one eye andaffect the other eye as well.
Open-angleglaucomaoccurs due to pressure buildup within the intraocular region. Thepressure is usually too high thus, compromising the health status ofthe eye (Ball et al., 2015). The condition is also characterised bythe loss of the optic nerve fibres. The state can also becharacterised by atrophy and cupping of the optic disc, which mightoccur in the nonexistence of any other causes of glaucomatousdisease. Continued damage to the optic nerve is responsible for theloss of vision in the later stages of the condition (Ball et al.,2015). The intraocular pressure buildup leads to the development offrequent headaches, and pain of the eye.
Oneof the evidence-based recommendations for eye health is to ensurethat one undergoes regularsight checks.In most medical conditions, prevention of greater damages can beundertaken once a problem is noted at the earlier stages (HeathyPeople.gov, 2013). Individuals should therefore, visit the opticiansfor a full examination of the eye on a regular basis. Some healthconditions such as diabetes are also known to affect the health ofthe eye. People who have such conditions, or have greater chances ofdeveloping such conditions should visit the opticians to check thehealth of the eye. Check-ups are essential for the early interventionof a health condition such as cataracts before much damage isexperienced (Healthy People.gov, 2013). Also, when noted and treatedearly, eye conditions such as cataracts can be reversed or treated.
Properdietis also recommended for healthy eyes. Unhealthy eating is known tocause diseases such as diabetes, which is known to affect the healthof the eyes. In fact, some individuals with Type 2 Diabetes and Type1 Diabetes are known to develop Diabetic Retinopathy (HealthyPeople.gov, 2013). Maintenance of healthy blood sugars and healthyblood fat levels in both types of diabetes is known to reduce thechances of developing Diabetic Retinopathy. One can lower the risk ofgetting Age-Related Macular Degeneration through the inclusion ofcertain foods in the diet. Development of cataracts can also beprevented through the intake of foods containing vitamin E, vitaminC, and omega-3 fatty acids. Foods that are rich in lutein andzeaxanthin are also known to help greatly in promoting the health ofthe eyes.
