Photo Essay: Retinal Changes in Type 3 Gaucher Disease

Area of Science:

• Ophthalmology
• Medical Genetics
• Biochemistry

Background:

• Gaucher disease is a rare genetic disorder characterized by the buildup of glucocerebroside in cells.
• Ocular manifestations of Gaucher disease are diverse, including gaze abnormalities and macular changes.
• Type 3 Gaucher disease is a severe neurological form with progressive symptoms.

Purpose of the Study:

• To report and characterize bilateral fovea sparing macular deposits in a patient with type 3 Gaucher disease.
• To investigate the potential correlation between retinal deposits and systemic disease burden.

Main Methods:

• Clinical case report of a 21-year-old woman with diagnosed type 3 Gaucher disease.
• Ophthalmic examination including funduscopy to assess macular features.
• Review of existing literature on ocular manifestations of Gaucher disease.

Main Results:

• The patient presented with bilateral macular deposits that specifically spared the fovea.
• These deposits are hypothesized to result from glucocerebroside accumulation within histiocytes in the retinal layers.
• The findings suggest a potential link between the extent of retinal involvement and systemic Gaucher disease severity.

Conclusions:

• Macular deposits, particularly fovea sparing, can be an ocular finding in type 3 Gaucher disease.
• Retinal histiocyte infiltration by glucocerebroside may underlie these deposits.
• Further research is warranted to confirm the correlation between ocular and systemic disease progression in Gaucher disease.
