Diagnosis: Phthisis bulbi
On CT scan with plain study: Left eye ball appears small with calcified lens and globe.
Phthisis bulbi, also known as end-stage eye, is an atrophic scarred, and disorganized globe that may result from a variety of severe ocular insults.
Clinical signs: Decreased intraocular pressure.
Prognosis: Phthisis bulbi is an end-stage condition with no chance of improvement.
Trochlear calcifications may occur in adults as aging-related normal variants or may be seen in young patients with diabetes mellitus. They typically have a superomedial location within the orbit.
Metastatic calcification: abnormal calcium and phosphate metabolism.
