Bilateral Sequential Profound Visual Loss in Tuberous Sclerosis

Area of Science:

• Ophthalmology
• Genetics
• Neurology

Background:

• Tuberous sclerosis (TSC) is an autosomal dominant disorder causing benign tumor growth in multiple organs.
• Ocular manifestations in TSC commonly include astrocytic hamartomas of the retina and optic nerve head.
• These retinal lesions typically have a benign clinical course with rare visual deterioration.

Observation:

• A 17-year-old male with a history of TSC presented with profound bilateral vision loss.
• The patient had a history of intracranial lesions, hydrocephalus, and optic nerve swelling.
• Asymmetric astrocytic hamartomas were noted in the optic nerve head and retina.

Findings:

• Despite the generally benign nature of ocular hamartomas in TSC, this patient experienced severe visual impairment.
• The case highlights a rare instance of catastrophic vision loss in a young patient with TSC.
• Complex interactions between neurological and ocular manifestations likely contributed to the vision loss.

Implications:

• This case underscores the potential for severe visual complications in tuberous sclerosis, even when rare.
• Understanding the mechanisms behind such vision loss is crucial for early detection and management.
• Further research into the factors influencing visual outcomes in TSC patients is warranted.
