Age-Related Macular Degeneration (AMD) is a relatively common visual impairment that is one of the leading causes of vision loss in older adults.
The ailment typically manifests in the form of blurriness of one’s central vision. While those diagnosed with AMD are unlikely to lose their vision completely, their vision can deteriorate to the point where common tasks such as driving and cooking become too difficult to perform safely.
While the condition has been known to damage the macula – a part of the retina that enables clarity in one’s central vision – the rate at which AMD develops can vary drastically from person to person. The condition typically progresses as a person ages.
It is common for most symptoms of AMD to be overlooked during its initial stages. However, these symptoms will grow to become more severe as the disease progresses.
Reduced central vision is a primary symptom of AMD, and the condition also has other negative consequences that include:
AMD is able to manifest in two different types: wet AMD and dry AMD. The former is associated with an increased rate of visual deterioration, while the latter tends to progress more gradually.
Wet AMD occurs when the macula scars as a result of leaked fluids or blood from abnormal blood vessels located under the retina. This causes a loss of central vision that causes your sight to become blurry, presenting a sign of an AMD condition.
Conversely, dry AMD happens as a consequence of the macula growing thinner as we age. This allows yellow protein deposits known as drusen to accumulate on the macula that results in reduced central vision.
Furthermore, AMD can be further classified into three stages: early, intermediate, and late. Dry AMD occurs throughout all three stages of AMD, while wet AMD solely appears at the later stages.
There are several health factors that are linked with an increased risk of developing AMD, such as being overweight or having an unhealthy diet. Here is a list of some risk factors associated with AMD:
Habitual smoking of cigarettes
Being 50 years of age or older
Eating a diet high in saturated fat
Having high blood pressure (hypertension)
Having a family history of AMD
Increased risk of heart diseases

An ophthalmologist will often recommend that a patient undergo an Optical Coherence Tomography (OCT) when signs of AMD manifest themselves. This procedure allows ophthalmologists to observe detailed photographs of the internals of one’s eye and pinpoint the nature and scope of the damage on the macula. Doctors would hence be able to determine both the type and severity of the condition.
Alternatively, AMD can also be diagnosed via a regular eye screening, which is a pain-free process. During this procedure, ophthalmologists examine a patient’s eyes for signs of AMD after the administration of eye drops that dilate the pupil.
At this current point in time, there is no known cure for AMD. However, there are many treatments developed to help manage the progression of the condition and mitigate its effects on their vision. At Eyecentric in Park City Medical Centre (PMC), there are many strong treatment options for AMD under Eyecentric, such as:
