A 45-year-old male presented with complaints of reduced vision in both eyes (BE) for the past one year. Visual acuity was 6/18 improving to 6/9 in right eye (RE) and 6/60 improving to 6/24 in left eye (LE) respectively. Slit-lamp examination of BE showed presence of central posterior sub-capsular cataract (PSC). In addition, LE showed radiating-feathery lenticular opacities resembling flower petals along with presence of central disc of PSC resembling flower pistil. A distinct transparent zone around the PSC delineating it from the surrounding rosette can be appreciated [Figure 1].

The patient didn't reveal any history of ocular trauma or drug abuse. There was no history of any systemic illness, metabolic disease, family history or previous ocular surgery. Intraocular pressure, gonioscopy and fundoscopy were unremarkable in BE. The patient underwent cataract surgery in LE with implantation of posterior chamber intraocular lens and had satisfactory visual outcome.
| Discussion|| |
Rosette-shaptxed lenticular opacification is usually seen in patients with blunt trauma, diabetes, lightning injury, exposure to infrared or ionizing radiations. The typical rosette shape is acquired due to the dysfunctional lens epithelium causing edema of the posterior cortical lens fibers and creating a lamellar zone of vacuolation. This vacuolation zone delineates the cortical sutures in the shape of a star along the architectural pattern of the lens, hence producing radiating feathery lines resembling flower petals [Figure 2].

Rosette cataract can occasionally regress after good glycemic control in diabetics. Similarly, trauma, Nd: Yag iridotomy or vitrectomy–induced rosette cataract can also undergo spontaneous remission.,
Our case is noteworthy because a fully-developed rosette cataract surrounding the pre-existing central PSC with a delineating transparent zone having negative history of ocular trauma or systemic illness has never been reported in the literature.
