Therapy-resistant dry itchy eyes.

Area of Science:

• Ophthalmology
• Nutrition Science
• Pediatrics

Background:

• Dry eye symptoms in children can be challenging to diagnose and treat.
• Persistent dry eye unresponsive to conventional therapies warrants investigation into underlying systemic causes.
• Vitamin A deficiency is a rare but significant cause of ocular surface disease.

Purpose of the Study:

• To highlight vitamin A deficiency as a critical differential diagnosis for pediatric dry eye.
• To present a case study of successful management of vitamin A-deficiency-related dry eye.
• To emphasize the importance of nutritional assessment in pediatric ophthalmology.

Main Methods:

• Clinical examination of an 8-year-old male with persistent dry eye.
• Laboratory confirmation of vitamin A deficiency.
• Treatment with vitamin A supplementation and nutritional counseling.
• 6-month follow-up to assess symptom resolution.

Main Results:

• The patient presented with multiple signs consistent with vitamin A deficiency.
• Laboratory tests confirmed low vitamin A levels.
• Vitamin A substitution therapy resulted in rapid improvement of dry eye symptoms.
• Nutritional counseling ensured sustained symptom-free status over 6 months.

Conclusions:

• Vitamin A deficiency should be considered in pediatric cases of unexplained dry eye.
• Early diagnosis and intervention, including supplementation and dietary modification, are crucial for effective management.
• This case underscores the importance of a holistic approach, integrating ophthalmology and nutrition, for pediatric eye health.
