How does senile cataract develop?

How does senile cataract develop?

Senile cataracts are part of the aging process and occur in both animals and humans. These lesions are frequently preceded by the formation of a dense nuclear sclerosis. Opaque streaks extend from the nucleus toward the cortical equator like spokes of a wheel.

What is the most common type of senile cataract?

Nuclear Sclerotic Cataracts This the more common type of age-related cataract. Its primary cause is the hardening and yellowing of the lens over time. It is referred to as “Nuclear” due to the centrally located clouding on the lens called the nucleus. The hardening of the lens is called “Sclerosis.”

Is senile cataract curable?

Senile cataract is a vision-impairing disease characterized by gradual, progressive thickening of the lens. It is the leading cause of blindness in the world today. This is unfortunate, considering that the visual morbidity brought about by age-related cataract is reversible.

What causes traumatic cataract?

Traumatic Cataract – Another common cause of cataracts is trauma: blunt or penetrating ocular trauma, electric shock, chemical burns or ionizing radiation. A traumatic cataract can develop even years after these types of eye injuries. Diabetes – People with diabetes are 60% more likely to develop cataracts.

What will happen if cataract is left untreated?

If left untreated, cataracts will eventually cause total blindness. The good news is that cataracts can be easily treated. The primary treatment for cataracts is surgery to remove and replace the cloudy lens. Cataract surgery is a simple procedure that typically takes just about 15 minutes to complete.

Can stress cause cataracts?

Because emotional or psychological stress is associated with increased oxidant production and oxidative damage, long-term exposure to emotional or psychological stressors may enhance the risk of many diseases associated with oxidative stress, including cataracts.

How will you manage a case of senile cataract?

The definitive management for senile cataract is lens extraction. Over the years, various surgical techniques have evolved from the ancient method of couching to the present-day technique of modern phacoemulsification. Phacoemulsification offers the advantage of a smaller incision size at the time of cataract surgery.

How long does a cataract operation take?

What Happens In Cataract Surgery? Patients spend about 2-4 hours in pre-op and surgery and another 2 hours or so resting afterward—mostly sleeping off the light medication that kept them calm during the procedure.

Can traumatic cataract be cured?

Conclusions: In this study, a majority of eyes with traumatic cataract were safely rehabilitated with posterior chamber lens implantation. Visual acuity improved in 90% of eyes; complications were seen in 15%.

What are the 3 types of cataracts?

A cataract is a clouding of the lens of the eye that impairs vision. There are three main types of cataract: Nuclear Sclerotic, Cortical and Posterior Subcapsular. The types of cataracts are classified based on where and how they develop in the eye.
