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.
The major symptom related to rosette shaped cataract is the clouding of the lens which could extend to the entirety of the lens.
Some of the causes for rosette cataract are:
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.
The treatment of rosette cataract 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.
If you’re thinking of getting your treatment done, do visit Dr. Agarwal’s Eye Hospital and consult with the best eye specialists. Walk in for a consultation and go back after a successful surgery the same day.
