Presbyopia Flashcards
a term used to indicate the condition whereby amplitude diminishes with increased age
Presbyopia
he said that “Presbyopia is not a disease, pathological condition or anomaly
it is an expected and inevitable concomitant of the physiologic, healthy aging process of humans”
K. Brookman 1996
he said that “the generally accepted cause of presbyopia is considered to be a sclerosis of the lens fibers and capsule”

Classification of Presbyopia:
- Absolute Presbyopia
- Incipient Presbyopia
- Premature Presbyopia
- Nocturnal Presbyopia
presbyopia in which accommodative ability is commonly absent
a presbyopia in which some convex lens power is necessary for reading small print
Absolute Presbyopia
early stage of presbyopia, beginning presbyopia
sometimes described as the stage in which small print may be read without the addition of convex lens power. but with effort
Incipient Presbyopia
Presbyopia manifested at an early age
before the age of 40 yrs
Premature Presbyopia
a reduction in the apparent amplitude of accommodation induced by the reduction of the intensity of illumination
Nocturnal Presbyopia
usual amplitude of accommodation of Presbyopia
Below 5.00 Diopters
in presbyopia the Positive relative accommodation is ____
decreasing
in presbyopia there is _____ exophoria or _____ esophoria at near
