What is traumatic cataract?
Traumatic cataract is a clouding of the lens that may occur after either blunt or penetrating ocular trauma that disrupts the lens fibers. Most traumatic cataracts are intumescent, but their type and clinical course depend on trauma mechanism and the integrity of the capsular bag.
Can hitting your head cause cataracts?
Physical injury or trauma: A blow to the eye, a cut or puncture, chemical burns, or electric shock; Radiation: Long-term exposure to ultraviolet radiation from the sun (both UVA and UVB); in addition, radiation used to treat certain types of head and neck cancers can cause cataracts to develop.
What causes cataracts to grow quickly?
Trauma-related cataracts are typically the most fast-growing type of cataracts. Radiation: Radiation-related cataracts, sometimes listed under trauma-related cataracts, occur after the lens has been exposed to radiation. Exposure to high levels of radiation can result in clouded vision in as little as two years.
What is the treatment for traumatic cataract?
According to Trivedi and Wilson, primary posterior capsulectomy and vitrectomy should be considered irrespective of age in children undergoing surgery for traumatic cataract. Pars plana lensectomy and vitrectomy may be best in cases of posterior capsular rupture, posterior dislocation, or extreme zonular instability.
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.
What are the symptoms of a secondary cataract?

What is oil drop cataract?
The oil-drop cataract is a common yet often overlooked cause of progressive vision loss. Although the nuclear change can be subtle on slitlamp biomicroscopic examination, retinoscopy reveals the classic oil droplet silhouetted against the red reflex.
How do you get a traumatic cataract?
Traumatic cataract is clouding of the lens and eyes that may occur after either blunt or penetrating ocular trauma that disrupts and damages the lens fibers. Most of the traumatic cataracts lead to eye lens swelling, but the type and clinical course depends on trauma and the integrity of the capsular bag.
How quickly can traumatic cataract form?
Traumatic cataracts can occur immediately after an eye injury or, in some cases, months or even years later. While cataracts that result from trauma can present unique challenges compared to age-related cataracts, skilled and experienced eye surgeons such as Dr.
How long does it take for a traumatic cataract to form?
Traumatic cataracts can occur as a result of a sharp penetrating injury to the lens capsule and/or lens, or a blunt concussive force. They may take days to years to develop. The diagnosis of traumatic cataracts is based on an abnormality in the red reflex.
What is the main cause of cataract?
Most cataracts develop when aging or injury changes the tissue that makes up the eye’s lens. Proteins and fibers in the lens begin to break down, causing vision to become hazy or cloudy. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts.
