[Corneal alterations in eyelid diseases]

Area of Science:

• Ophthalmology
• Corneal disease
• Eyelid pathology

Background:

• Corneal complications are common in patients with eyelid diseases.
• These complications significantly impact disease management and patient outcomes.
• Manifestations range from refractive errors to severe corneal damage.

Purpose of the Study:

• To review the spectrum of corneal changes associated with various eyelid diseases.
• To elucidate the pathophysiological mechanisms linking eyelid and corneal conditions.
• To highlight the clinical relevance for ophthalmologists and eye care professionals.

Main Methods:

• Literature review of studies on eyelid diseases and associated corneal pathologies.
• Analysis of pathophysiological factors including mechanical, inflammatory, and infectious causes.
• Categorization of eyelid conditions and their specific corneal sequelae.

Main Results:

• Corneal changes include refractive anomalies, degeneration, ocular surface disease, infiltrates, vascularization, ulceration, and perforation.
• Pathophysiological mechanisms involve compressive forces, exposure, trichiasis, distichiasis, eye rubbing, inflammation, and infection.
• Associated eyelid diseases encompass malposition, tumors, infections, dermatitis, blepharitis, meibomitis, and Meibomian gland dysfunction.

Conclusions:

• Eyelid diseases represent a significant risk factor for diverse corneal pathologies.
• Prompt diagnosis and management of eyelid conditions are essential to prevent or mitigate corneal damage.
• A comprehensive understanding of the eyelid-cornea relationship is vital for optimal patient care.
