 H/o trauma at the age of 5yrs to left eye

On usg-





The globe is reduced in size (usually <20 mm) with a thickened/folded posterior sclera. Dystrophic calcification is common, and osseous metaplasia sometimes occurs, forming what is called "intraocular bone". 




  • small and shrunken globe with foci of calcium deposits and ossification in the sclera, cornea, lens, retina, and optic nerve
  • distortion of globe components with challenging to separate and identify structures
  • fibrotic scarring with irregular globe contour and diffusely increased attenuation
