What is Rosette Cataract?

Rosette cataract is a type of traumatic cataract. Traumatic cataract is the clouding of the lens that occurs either by blunt trauma to the head or eye region or penetrating ocular trauma resulting in the disruption of the lens fibers. This in turn prevents a clear image from forming on the retina. As mentioned, a rosette cataract can be formed by the sudden impact of blunt force. This holds true specially if the impacted area is or around the eye-ball. 60% of traumatic cataracts happen after the onset of minor concussion. The rosette cataract may be stable or progressive and can occur due to various shearing forces that introduce pathologic changes to the lenticular composition.

Rosette Cataract Symptoms

The major symptom related to rosette shaped cataract is the clouding of the lens which could extend to the entirety of the lens.

Causes of Rosette Cataract

Some of the causes for rosette cataract are:

  • Blunt force trauma to the head

  • Ocular trauma to the eyeball

  • Exposure to radiation

  • Electrocution

  • Chemical burns

Rosette Cataract Types

Rosette cataract is one of the most common traumatic cataracts involving blunt force trauma following both concussion and perforating injuries. It can occur either in the presence or the absence of a capsular tear. 

Early rosette cataract – The formation of early rosette cataract occurs in the anterior capsule and sometimes in posterior capsules or both simultaneously. It generally appears as feathering lines of opacities along the star shaped suture line.

Late rosette cataract – The formation of late rosette cataract generally occurs a few years after an injury. It is usually found deep lying in the cortex and nucleus and develops in the posterior cortex. This type of cataract has sutural extensions that are shorter and more compact as compared to early rosette. 

Rosette Cataract Treatment

The rosette cataract treatment can be done through surgery. The surgical treatment is generally selected depending on the morphology and the condition of the tissues other than only the lens.

When the cataract is membranous, membranectomy and anterior vitrectomy is done via either the anterior or the pars plana route. In cases where the lens has a white soft type rosette cataract, unimanual or bimanual aspiration is carried out. The process of phacoemulsification is carried out in the case of hard, large nuclei.

When phacoemulsification is carried out, the cataract is broken into small particles and taken out by the surgeon. An intraocular lens is implanted. This is done even when the anterior lens capsule has been ruptured. Intraocular implantation is generally preferred in the case of corneal injury. The whole surgery can be done in less than an hour.

Frequently Asked Questions (FAQs)

What defines a rosette cataract?

A rosette cataract is a specific type of cataract characterized by the formation of star-shaped or rosette-like opacities in the lens of the eye. These opacities can obstruct vision and cause visual disturbances.

Common visual symptoms associated with rosette cataracts include blurred vision, glare, difficulty seeing in low light conditions, and decreased visual acuity. These symptoms can progressively worsen as the cataract develops.

Rosette cataracts typically develop due to the clumping or aggregation of lens fibers within the eye’s lens. This aggregation causes areas of opacity to form, resembling rosettes or star shapes. The exact cause of rosette cataracts may vary but can be influenced by factors such as age, genetics, and environmental factors.

Specific risk factors linked to the occurrence of rosette cataracts may include advancing age, a family history of cataracts, certain medical conditions such as diabetes or metabolic disorders, prolonged exposure to sunlight or UV radiation, smoking, and certain medications such as corticosteroids.

Treatment options for rosette cataracts at Dr Agarwals Eye Hospital may include surgical intervention, such as phacoemulsification with intraocular lens implantation. During this procedure, the cloudy lens affected by the cataract is removed and replaced with an artificial intraocular lens (IOL) to restore clear vision. The specific treatment approach will depend on the individual patient’s eye health, the severity of the cataract, and other factors assessed during a comprehensive eye examination by an ophthalmologist at the hospital. It’s important to consult with an eye care professional for personalised treatment recommendations.
