Question: Frequent change of presbyopic glasses is an early symptom of

a. closed angle glaucoma b. open angle glaucome c. senile cataract d. after cataract

Answer: c. senile cataract

One of the early symptoms of senile cataract is frequent change in presbyopic glasses. Presbyopia is the term for age-related loss of close vision resulting from firmness in the lens. Age-related senile cataract is characterized by loss of lens clarity and hardening with denaturation forming protein clumps that accumulate.

In the course of developing a senile cataract, the lens becomes more and more opaque and rigid. This affects its refraction and accommodation especially at the near point. The upgrade of the lens change in patients with emerging cataract is so visible to them that they make frequent changes in their near glasses. Finally, they end up being nearsighted as well as presbyopia.

On the other hand, open and closed angle glaucoma has no influence on lens accommodation or presbyopia. Glaucoma occurs due to optic nerve damage caused by pressure inside the eye. Secondary cataract, which follows the surgery for a cataract and not associated with aging is also known as after-catarcat.

In conclusion, the need for presbyopic glasses to be constantly reinforced is typical of senile cataracts as they age because this lens loses transparency and flexibility. This makes it different from other age-related eye disorders such as glaucoma or post cataract.
