Several studies have found a broad range of incidence of PVD, from 20% of autopsy cases to 57% in a more elderly population of patients (average age was 83.4 years). [4] People with myopia (nearsightedness) greater than 6 diopters are at higher risk of PVD at all ages. Posterior vitreous detachment does not directly threaten vision.
It most commonly occurs in people over the age of fifty and in the United States is the most common cause of vision loss in this age group. [1] [3] About 0.4% of people between 50 and 60 have the disease, while it occurs in 0.7% of people 60 to 70, 2.3% of those 70 to 80, and nearly 12% of people over 80 years old. [3]
Fundus of geographic atrophy. Geographic atrophy (GA), also known as atrophic age-related macular degeneration (AMD) or advanced dry AMD, is an advanced form of age-related macular degeneration that can result in the progressive and irreversible loss of retinal tissue (photoreceptors, retinal pigment epithelium, choriocapillaris) which can lead to a loss of central vision over time.
In the young (under 50 years of age), these cells occasionally pull free and disintegrate on their own; but in the majority of those affected (over 60 years of age) the condition is permanent. The underlying photoreceptor cells , rod cells and cone cells , are usually not damaged unless the membrane becomes quite thick and hard; so usually ...
Keeping a sense of balance requires the brain to process a variety of information received from the eyes, the nervous system, and the inner ears. If the brain is unable to process these signals, such as when the messages are contradictory, or if the sensory systems are improperly functioning, an individual may experience lightheadedness or ...
The majority of people with poor vision are in the developing world and are over the age of 50 years. [1] Rates of visual impairment have decreased since the 1990s. [1] Visual impairments have considerable economic costs both directly due to the cost of treatment and indirectly due to decreased ability to work. [16]
Most women over 60 have entered a new phase in life and health: post-menopause. According to Dr. Tara Scott, MD , gynecologist and Medical Advisor at Versalie, by the age of 60, most women are ...
Dilated fundus examination (DFE) is a diagnostic procedure that uses mydriatic eye drops to dilate or enlarge the pupil in order to obtain a better view of the fundus of the eye. [1] Once the pupil is dilated, examiners use ophthalmoscopy to view the eye's interior, which makes it easier to assess the retina , optic nerve head , blood vessels ...
