Best's Disease in a 20-Month-Old Child

Area of Science:

• Ophthalmology
• Genetics
• Medical Diagnostics

Background:

• Best disease is an autosomal dominant genetic disorder affecting the macula.
• It is characterized by progressive, bilateral vitelliform macular lesions.
• The condition's onset and progression can vary significantly among individuals.

Purpose of the Study:

• To report the youngest documented case of Best disease.
• To highlight the early diagnosis of hereditary Best disease in a pediatric patient.
• To emphasize the utility of photographic documentation in early diagnosis.

Main Methods:

• Clinical examination of a 20-month-old child presenting with symptoms suggestive of macular disease.
• Genetic assessment to confirm autosomal dominant inheritance.
• Ophthalmic imaging, likely including fundus photography, to document vitelliform macular lesions.

Main Results:

• A 20-month-old child was diagnosed with hereditary Best disease.
• The diagnosis was confirmed through photographic documentation of characteristic macular lesions.
• The patient inherited the condition from his father.

Conclusions:

• Early diagnosis of Best disease is possible, even in very young children.
• Photographic documentation is a crucial tool for diagnosing Best disease.
• This case expands the understanding of the earliest presentations of this genetic macular disorder.
