Insights

This study details unique retinal abnormalities in an infant with muscle-eye-brain disease, including congenital retinal detachment and foveal dysplasia. Aberrant retinal vasculogenesis is proposed as a novel mechanism.

Area of Science:

  • Ophthalmology
  • Genetics
  • Developmental Biology

Background:

  • Muscle-eye-brain disease is a rare genetic disorder characterized by neuronal migration defects.
  • Congenital retinal detachment is a severe condition that can lead to vision loss.
  • Understanding the ocular manifestations of genetic disorders is crucial for early diagnosis and management.

Purpose of the Study:

  • To report novel retinal findings in an infant diagnosed with muscle-eye-brain disease.
  • To propose a new mechanism contributing to congenital retinal detachment in this condition.

Main Methods:

  • A case report was utilized to describe the clinical presentation and findings.
  • Ophthalmic examination and genetic testing were performed to confirm the diagnosis.

Main Results:

  • The infant presented with total retinal detachment, peripheral retinal avascularity, and neovascularization in one eye.
  • The other eye showed optic nerve hypoplasia and foveal dysplasia with peripheral avascularity.
  • Genetic testing confirmed muscle-eye-brain disease, a disorder of aberrant neuronal migration.

Conclusions:

  • This case highlights previously unreported retinal findings in muscle-eye-brain disease, including peripheral avascularity leading to retinal detachment and foveal dysplasia.
  • Disordered retinal neuron migration and patterning are suggested as the cause of aberrant retinal vasculogenesis and detachment.
