A 44 year old man notices that in the last few months he is having blurred vision at normal reading distance. He has to hold reading materials at arm's length to read properly. He also complains of eye fatigue and headaches. Examination, including fundoscopy were unremarkable.
The most likely pathology is?
a) presbyopia b) age-related macular degeneration c) bilateral occipital lobe infarcts d) conversion disorder e) retinal detachment
Correct Answer: A
Explanation:
The most common ocular complaint over 40 years old is a diminished ability to focus clearly at normal (less than arm's length) reading distances. This is called presbyopia . Presbyopia is caused by thickening of the lens within the eye. In the older eye, the already thickened lens responds more slowly to changes in tension of the elastic capsule.
