Common perceptual, neurological, or cognitive issue and contributing factors

Perceptual Issue: Age-Related Macular Degeneration (AMD)

Description of the Issue:

Age-Related Macular Degeneration (AMD) is a common progressive eye condition that primarily affects the macula, the central part of the retina responsible for sharp, central ¹ vision needed for activities like reading, driving, and recognizing faces. AMD ² causes a gradual deterioration of this central vision, while peripheral vision typically remains intact. Individuals with AMD may experience blurry or distorted central vision, difficulty seeing fine details, and the appearance of a dark or blurry spot in the center of their visual field. In advanced stages, it can lead to significant vision loss, although complete blindness is rare.  

Contributing Factors:

AMD is a multifactorial condition, meaning several factors contribute to its development and progression. These include:

• Age: This is the most significant risk factor. AMD is most common in people over the age of 60.
• Genetics and Family History: Having a family history of AMD significantly increases an individual’s risk. Specific genes have been identified that are associated with an increased susceptibility to the condition.
• Smoking: Smoking is a well-established modifiable risk factor. Smokers are at a higher risk of developing AMD and its progression to more advanced stages.
• Cardiovascular Disease: Conditions affecting the heart and blood vessels, such as high blood pressure and high cholesterol, may increase the risk of AMD due to reduced blood flow to the retina.
• Obesity: Some studies suggest a link between obesity and an increased risk of advanced AMD.
• Diet: A diet low in antioxidants and certain vitamins and minerals may contribute to the development or progression of AMD.
• Sunlight Exposure: While the evidence is not conclusive, some research suggests that long-term exposure to ultraviolet (UV) light may increase the risk of AMD.
• Race: Caucasians have a higher prevalence of AMD compared to other racial groups.

Steps for Prevention or Health Promotion for the Patient and Family:

Given the contributing factors, several steps can be recommended for prevention and health promotion:

For the Patient:

• Regular Eye Examinations: Annual dilated eye exams by an ophthalmologist or optometrist are crucial for early detection of AMD and other eye conditions. Early detection allows for timely intervention and management.
• Smoking Cessation: If the patient smokes, strongly encourage and support smoking cessation. This is one of the most significant modifiable risk factors. Provide resources and referrals for smoking cessation programs.
• Healthy Diet: Promote a diet rich in fruits, vegetables (especially leafy greens like kale and spinach), and omega-3 fatty acids (found in fish like salmon). Emphasize foods containing antioxidants like lutein and zeaxanthin, which are beneficial for macular health. Consider discussing the potential benefits of specific eye-healthy supplements if recommended by an eye care professional.
• Manage Cardiovascular Risk Factors: Encourage the patient to manage conditions like high blood pressure and high cholesterol through lifestyle modifications (diet, exercise) and prescribed medications, as advised by their primary care physician.
• Maintain a Healthy Weight: If the patient is overweight or obese, encourage weight loss through a balanced diet and regular physical activity.
• UV Protection: Advise the patient to wear sunglasses that block 99-100% of UVA and UVB radiation when outdoors, even on cloudy days.
• Home Modifications: As vision changes occur, suggest modifications to improve safety and independence, such as good lighting, large-print materials, and assistive devices.
• Utilize Low Vision Aids: If vision loss progresses, encourage the patient to explore low vision aids and strategies, such as magnifiers, telescopic glasses, and adaptive technology.

For the Family:

• Encourage Regular Eye Exams: If there is a family history of AMD, encourage other family members, especially those over 50, to have regular comprehensive eye exams.
• Support Healthy Lifestyle Choices: Encourage and participate in healthy eating habits and regular physical activity as a family. Support the patient in their efforts to quit smoking.
• Create a Supportive Environment: Understand the challenges the patient may face with vision loss and offer emotional and practical support. This may include assisting with tasks that require sharp central vision, providing transportation, and creating a safe and accessible home environment.
• Learn About AMD: Educate yourselves about AMD, its progression, and available resources to better understand and support the patient.
• Accompany to Appointments: Offer to accompany the patient to eye appointments to provide support and help with understanding and remembering information.

Public Health Departments or Local Resources in Kenya for Support:

Identifying specific local resources in Kenya requires knowledge of the exact geographical area. However, here are general types of public health departments and local resources that the patient and family could reach out to for support related to vision health and chronic conditions:

• Ministry of Health (MOH) – National and County Levels: The MOH is the primary government body responsible for public health in Kenya. They often have departments or programs focused on non-communicable diseases (NCDs), which may include eye health initiatives. Contacting the local County Health Department would be a good starting point to inquire about vision health programs, awareness campaigns, and potential partnerships with eye care professionals.
• Local Public Health Centers and Dispensaries: These facilities, run by the government or non-governmental organizations (NGOs), often provide primary healthcare services and may conduct basic eye screenings or refer patients to specialists. They can also offer health education and advice on managing chronic conditions.
• Ophthalmological Societies and Associations: Kenya likely has professional organizations for ophthalmologists and other eye care professionals. These organizations may have information on eye health, local specialists, and support groups. Searching online for “Ophthalmological Society of Kenya” or similar terms could yield valuable contacts.
• Non-Governmental Organizations (NGOs) Focused on Eye Health: Several national and international NGOs work in Kenya to improve eye health and prevent blindness. Researching NGOs active in the patient’s region could connect them with valuable resources, including eye screenings, low vision services, and support networks. Examples of international organizations working on eye health globally include Orbis International, Sightsavers, and the Fred Hollows Foundation. Local Kenyan NGOs may also exist.
• Organizations Supporting People with Disabilities: Organizations that support individuals with disabilities may offer resources and support services for people experiencing vision loss due to AMD, such as assistive technology training and peer support groups.
• Community Health Workers (CHWs): CHWs often work within local communities to provide health education and connect individuals with healthcare services. They can be a valuable link to information and resources within the patient’s specific area.

To find the most relevant local resources, the patient or family should:

• Contact their local public health center or dispensary.
• Ask their primary healthcare provider for referrals to eye specialists or support organizations.
• Conduct online searches using specific keywords related to eye health and disability support in their county or region of Kenya.
• Inquire within their community networks for information about local support groups or organizations.

By addressing modifiable risk factors and utilizing available resources, individuals with or at risk of AMD can take proactive steps to protect their vision and manage the condition effectively.
