Retinal dystrophy in Jeune's syndrome.

Area of Science:

• Ophthalmology
• Genetics
• Pediatrics

Background:

• Jeune syndrome (νεφροφθαλμική δυσπλασία) is an autosomal-recessive disorder.
• It is characterized by skeletal, renal, and ocular abnormalities.
• While often fatal in infancy due to respiratory issues, some patients survive to adulthood.

Observation:

• This study followed two siblings with Jeune syndrome for 3.7 years.
• Visual field and electroretinogram (ERG) testing were used for monitoring.
• Evidence of disease progression was observed in both patients.

Findings:

• Progressive electroretinographic abnormalities were documented.
• One patient showed a decrease in rod and cone responses.
• The other patient exhibited an increased b-wave implicit time with 30-Hz flicker stimulation.

Implications:

• Ocular abnormalities in Jeune syndrome can progress over time.
• This progression impacts visual function and prognosis.
• Findings are crucial for genetic counseling and long-term patient management.
