Introduction
Pressing on the corner of the eye and hearing a crackling sound may be caused by tissue friction or air in the tear sac, which is considered a normal phenomenon. However, conditions such as dry eye syndrome or tear duct insufficiency can also trigger this symptom; therefore, it is recommended to seek medical attention promptly for early diagnosis and treatment. Avoid staying in environments with excessive dust or particulate matter, minimize exposure to such settings, and refrain from rubbing your eyes with dirty hands.
Pressing on the corner of the eye may produce a crackling or squeaking sound, which could be caused by tissue friction or air in the tear sac. This is generally considered a normal phenomenon. On the other hand, conditions such as dry eye syndrome or lacrimal drainage system dysfunction may also trigger this symptom. It is advisable to seek medical attention promptly for early diagnosis and treatment.
1. Normal Phenomenon
The squeaking sound when pressing on the eyes occurs due to friction between fluid and gas within the conjunctival sac, or possibly because of trapped air in the lacrimal sac. This condition is usually a normal physiological occurrence and does not require specific treatment.
2. Dry Eye Syndrome
Dry eye syndrome is a very common ophthalmic condition, typically caused by abnormal secretion or distribution of tears. Symptoms mainly include dryness, foreign body sensation, burning, photophobia, blurred vision, and eye fatigue. In some cases, a crackling sound may also occur when pressing on the corner of the eye. Usually, treatment involves using artificial tear eye drops as directed by a physician. Additionally, treatments can be combined with moisture chamber glasses or silicone eye masks to enhance effectiveness.
3. Lacrimal Drainage System Dysfunction
A noticeable sound when pressing on the eye corner may indicate lacrimal drainage system dysfunction. The human lacrimal apparatus consists of the tear secretion system and the tear drainage system. Tears are secreted by the lacrimal glands, lubricate the eye surface, and then drain through the nasolacrimal duct into the nasal cavity. Typically, a lacrimal irrigation test should first be performed to check for any blockage. If a blockage is present, probing of the tear ducts may be used for treatment. For punctal stenosis (narrowing of the tear duct opening), dilators can be used to enlarge the puncta; in some cases, surgical intervention may be necessary to widen the openings.
To prevent complications, avoid prolonged exposure to dusty or particle-filled environments. Minimize contact with such environments, avoid rubbing the eyes with dirty hands, and ensure that personal hygiene items such as towels and basins are cleaned and disinfected regularly, to prevent bacteria from unclean tools or hands entering the eyes.
