How genetics works? An illustrative case report

Area of Science:

• Ophthalmic Genetics
• Pediatric Ophthalmology
• Medical Genetics

Background:

• A four-year-old boy presented with severe vision loss in his right eye and milder impairment in the left.
• Ocular findings included a falciform retinal fold with exudates and peripheral pigmentation in the right eye, and temporal dragging of vessels with laser scars in the left.
• Systemic features included developmental delay, obesity, dysmorphic facies, and tapered fingers, suggesting a complex genetic disorder.

Observation:

• A four-year-old boy presented with severe vision reduction in the right eye and mild impairment in the left.
• Ocular examination revealed a falciform retinal fold, exudates, and pigmentation in the right eye, and vessel dragging with laser scars in the left.
• Systemic features included developmental delay, obesity, dysmorphic facies, and tapered fingers.

Findings:

• The patient's combined ocular and systemic features suggest a specific, undiagnosed genetic disorder.
• A systematic, step-wise diagnostic strategy was employed to investigate the potential genetic condition.
• The case illustrates the utility of modern ocular genetics in diagnosing complex pediatric cases.

Implications:

• This case underscores the importance of a thorough, integrated approach to diagnosing pediatric patients with suspected genetic disorders.
• Cost-efficient genetic testing strategies can significantly improve diagnostic yield and patient management.
• Advances in ocular genetics offer new hope for diagnosing and potentially treating rare genetic eye diseases.
