Correction of entropion and ectropion

Area of Science:

• Ophthalmology
• Oculoplastics
• Ocular Surface Disease

Background:

• The ocular surface requires intact eyelids and adnexal structures for proper function.
• Eyelid malpositions, including entropion and ectropion, are common and can compromise ocular surface health.
• These conditions pose significant risks to the success of ocular surface and intraocular surgeries.

Purpose of the Study:

• To provide a comprehensive overview of eyelid malpositions (entropion and ectropion).
• To discuss the etiology, clinical examination, and surgical management principles for these conditions.
• To describe practical surgical techniques for common and effective eyelid malposition corrections.

Main Methods:

• Review of causes of congenital and acquired eyelid malpositions (involutional, cicatricial, paralytic).
• Description of clinical examination techniques for assessing eyelid anatomy and function.
• Explanation of surgical principles and step-by-step surgical procedures for corrective operations.

Main Results:

• Detailed classification of entropion and ectropion based on etiology.
• Emphasis on the importance of thorough clinical assessment for surgical planning.
• Demonstration of surgical techniques to restore normal eyelid anatomy and function.

Conclusions:

• Understanding the causes and proper examination of eyelid malpositions is crucial for successful surgical outcomes.
• Effective surgical correction of entropion and ectropion can preserve ocular surface integrity and improve surgical success rates.
• This chapter serves as a guide to the principles and practice of eyelid malposition surgery.
