Vernal Keratoconjunctivitis: an update focused on clinical grading system.

Area of Science:

• Ophthalmology
• Pediatric Allergy
• Ocular Surface Disease

Background:

• Vernal keratoconjunctivitis (VKC) is a severe, chronic inflammatory eye condition primarily affecting children.
• Prevalence is low, but symptoms like conjunctival hyperemia and papillary hypertrophy necessitate accurate diagnosis.
• Current diagnostic methods lack standardization, complicating disease management.

Purpose of the Study:

• To provide an updated overview of Vernal keratoconjunctivitis (VKC).
• Focus on clinical grading systems for VKC diagnosis and severity assessment.
• Review recent literature published in the last decade.

Main Methods:

• Literature search of scientific databases for papers on VKC.
• Focus on studies published within the last 10 years.
• Analysis of clinical grading systems and diagnostic criteria.

Main Results:

• No standardized diagnostic criteria currently exist for VKC.
• Lack of uniformity in defining VKC disease severity.
• Difficulty in accurate diagnosis and treatment due to inconsistent criteria.

Conclusions:

• VKC symptoms overlap significantly with allergic conjunctivitis.
• Need for probable, possible, or improbable diagnostic criteria.
• Development of parameters to aid pediatricians in referring patients to ophthalmologists for confirmation.
