Abstract Details

Purpose:

To describe a case of rapid-onset bilateral cataract in a young patient with Fahrﾒs syndrome secondary to hypoparathyroidism.

Setting:

Fahr's disease (idiopathic basal ganglia calcification) is a rare disorder in which there are calcium deposits in the basal ganglia as a complication of hypoparathyroidism. The Fahr triad consists of symmetrical calcification of the basal ganglia, neuropsychiatric symptoms, and hypofunction of the parathyroid gland.

Methods:

A 24-year-old woman was addressed to the ophthalmology clinic with a complaint of rapidly progressive bilateral blurry vision. She had a history of epilepsy, hypoparathyroidism and severe hypocalcemia (60 ng/l), and was recently diagnosed with Fahrﾒs disease. Upon examination, her best corrected visual acuity (BCVA) was counting fingers, the eyelids presented a generalized cutaneous desquamation. She suffered from dry eye with reduced break-up time test bilaterally and superficial punctate inferior keratitis in both eyes. She presented a bilateral dense posterior subcapsular cataract associated to a cortical type. Fundoscopy was unsuccessful due to the density of the cataract.

Results:

The patient was prescribed artificial tears and ointment, and an ocular ultrasonography was requested to study the posterior segment. The biology assessment showed a persistent severe hypocalcemia even with supplementary treatment, which required to delay cataract surgery until the full stabilization of the patientﾒs clinical and biology assessment.

Conclusions:

This case is noteworthy because it illustrates a rare etiology of cataracts in young patients, but also because it presents a challenge for its management, given that such cases of metabolic cataracts are at high risk of post-operative complications.
