Pterygium and dry eye--a clinical correlation

Area of Science:

• Ophthalmology
• Corneal diseases
• Ocular surface disease

Background:

• Pterygium is a common ocular surface condition.
• The impact of pterygium on tear film dynamics is not fully understood.
• Assessing tear film quality is crucial for ocular surface health.

Purpose of the Study:

• To evaluate tear film function in patients with pterygium.
• To compare tear film parameters between pterygium patients and healthy controls.
• To determine if pterygium affects tear film adequacy.

Main Methods:

• Schirmer's test was performed on 56 eyes with pterygium.
• Tear film break-up time (BUT) was measured in the same eyes.
• Results were compared to 50 eyes of age-, sex-, and geographically-matched healthy controls.

Main Results:

• Schirmer's test values were significantly reduced in pterygium patients.
• Tear film break-up time (BUT) was significantly lower in pterygium patients.
• These findings indicate inadequate tear film in individuals with pterygium.

Conclusions:

• Pterygium is associated with impaired tear film function.
• Reduced tear film adequacy may contribute to ocular discomfort in pterygium patients.
• Further research should explore the clinical implications of these findings.
