Area of Science:

  • Ophthalmology
  • Endocrinology
  • Genetics

Background:

  • Partial lipodystrophy is a rare condition characterized by loss of subcutaneous fat.
  • Retinal pigment epithelial changes can be associated with various systemic and genetic disorders.

Observation:

  • A 27-year-old Lebanese woman presented with incidental findings of cuticular drusen and retinal pigment epithelial changes.
  • Despite macular involvement, her visual acuity remained normal.

Findings:

  • The patient exhibited hypocomplementaemia, impaired glucose tolerance, and mild hypertriglyceridaemia.
  • A notable finding was the complete absence of growth hormone response to hypoglycemia.
  • Continuous infusion of glucose with model assessment (CIGMA) indicated low-normal tissue insulin sensitivity and high-normal pancreatic beta cell function.

Implications:

  • The simultaneous occurrence of partial lipodystrophy and retinal pigmentary changes suggests a newly recognized syndrome.
  • This case expands the understanding of lipodystrophy spectrum disorders and their ocular manifestations.
  • Further research is warranted to elucidate the genetic and pathophysiological basis of this syndrome.
