The wrinkle sign in tear duct obstruction

Area of Science:

• Ophthalmology
• Oculoplastics

Background:

• Tear duct obstruction affects the nasolacrimal drainage system.
• Accurate diagnosis is crucial for effective treatment of punctal and canalicular obstructions.

Purpose of the Study:

• To introduce and describe the
• wrinkle sign
• a novel skin configuration observed during tear duct probing.
• To evaluate the clinical significance of the
• wrinkle sign
• in diagnosing specific types of tear duct obstructions.

Main Methods:

• The study describes the technique for eliciting the
• wrinkle sign
• during tear duct probing.
• Case observations of patients with canalicular and common internal punctal obstruction were analyzed.

Main Results:

• The
• wrinkle sign
• is a distinct skin configuration observed in specific tear duct obstruction cases.
• Its presence is correlated with the obstruction type.

Conclusions:

• The
• wrinkle sign
• is a useful clinical sign.
• It serves as a valuable adjunct to standard tear duct probing for diagnosing canalicular and common internal punctal obstruction.
