What does a traumatic cataract look like?

Cataracts caused by blunt trauma classically form stellate- or rosette-shaped posterior axial opacities that may be stable or progressive, whereas penetrating trauma with disruption of the lens capsule forms cortical changes that may remain focal if small or may progress rapidly to total cortical opacification.

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.

What is traumatic Iridodialysis?

Traumatic Iridodialysis after blunt eye trauma. Iridodialysis is the disinsertion of the iris from the scleral spur. It is in contrast from cyclodialysis, which is disinsertion of the ciliary body from the scleral spur. This patient suffers from monocular diplopia and glare.

Can you get a cataract from trauma?

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.

How do you treat a traumatic cataract?

Traumatic Cataract Treatment In eyes with existing injuries, if the lens damage is clear and extensive with cortical material in the anterior chamber, lens removal is performed at the same time as repair of the cut in the cornea, termed as the primary procedure.

WHAT IS lens subluxation?

In lens subluxation, zonular fibers are broken, and the lens is no longer held securely in place but remains in the pupillary aperture. Lens dislocation occurs following complete disruption of the zonular fibers and displacement of the lens from the pupil. Trauma is the leading cause of lens dislocation.

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%.

Can a traumatic cataract be cured?

What type of trauma causes cataracts?

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 is the morphology of traumatic cataracts?

Most traumatic cataracts are intumescent, but their type and clinical course depend on trauma mechanism and the integrity of the capsular bag. The morphology of a classic traumatic cataract is referred to as a rosette or stellate type ( Fig. 1 ).

What are the signs and symptoms of iatrogenic surgical trauma to the iris?

Patients at high risk for iatrogenic surgical trauma to the iris, include those with a history or a predisposition of Intra-operative Iris Floppy Syndrome (IFIS), psuedoexfoliation syndrome, or history of iritis. Patients with photic symptoms due to iris defects report glare, haloes in brightly lit conditions, and trouble reading.

Can trauma cause cataracts to develop?

A history of trauma is necessary but may not be recent, as cataracts often develop slowly, and may appear years after the incident. Traumatic cataracts can be unilateral or bilateral. Injury due to blunt trauma is most commonly encountered, although penetrating trauma and other non-mechanical agents can also cause them [1] [2].

What are the visual signs of traumatic iritis?

Some of the visual signs of traumatic iritis, such as ciliary flush, Vossius ring, and hypopyon, can be seen with the naked eye. Others, like cell and flare or synechiae, require a special high-powered microscope called a slit lamp to view inside the eye.
