Traumatic cataracts occur secondary to blunt or penetrating ocular trauma. Infrared energy (glass-blower’s cataract), electric shock, and ionizing radiation are other rare causes of traumatic cataracts.
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 meant by 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 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%.
How do you treat a 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.
How common is traumatic cataract?
Traumatic cataracts occur in 24% of patients with globe contusions across the globe. A concussion cataract may occur due to and in a blunt trauma.
At what stage should cataracts be removed?
In most cases, you need surgery when blurry vision and other symptoms of a cataract starts to interfere with daily activities like reading or driving. There is no drug or eye drop to prevent or treat cataracts. Removing them is the only treatment.
What causes oil drop cataract?
Bilateral lens changes. Zonular or nuclear opacity with increased refractive power of the nuclear portion causes an “oil droplet” appearance on retroillumination. Lenticular myopia.
Can cataract surgery cause trauma to the eye?
Depending on the surgical approach during cataract surgery, up to 20% loss of endothelial cells has been reported. Lenticular injuries comprise 7% of ocular trauma, and they are the most common type of complication from penetrating ocular injuries that result in loss of vision.
Can eye injury cause cataracts?
Penetrating ocular injury may induce a cataract by puncturing the lens capsule, and the eye may still contain this intraocular foreign body. Blunt ocular injury can cause a diffuse cataract with a higher chance for zonular loss.
How common is congenital cataracts?
Congenital cataract are one of the most common treatable causes of visual impairment and blindness during infancy, with an estimated prevalence of 1 to 6 cases per 10,000 live births.
What does vision look like with cataracts?
Cataract Symptom: Blurry Vision
Blurry vision at any distance is the most common symptom of cataracts. Your view may look foggy, filmy, or cloudy. Over time, as the cataracts get worse, less light reaches the retina. People with cataracts may have an especially hard time seeing and driving at night.
