Summary
This study found that patients with unilateral pterygium experience reduced tear secretion in the affected eye, indicating a link between dry eye and pterygium. Further research is needed to confirm this association.
Area of Science:
- Ophthalmology
- Dry Eye Disease Research
- Ocular Surface Disease
Background:
- Pterygium is a common ocular surface condition.
- Dry eye disease is a prevalent condition affecting tear film stability.
- The relationship between pterygium and dry eye is not fully understood.
Purpose of the Study:
- To investigate the correlation between the presence of pterygium and dry eye.
- To assess basic tear secretion in patients with unilateral pterygium.
Main Methods:
- A prospective study was conducted on 30 patients diagnosed with unilateral pterygium.
- Schirmer's test with anesthesia was performed on both eyes of each patient to measure tear secretion.
- Tear secretion values were compared between the eye with pterygium and the contralateral healthy eye.
Main Results:
- The mean Schirmer's test value in the eye with pterygium was 11.6 +/- 0.4 mm.
- The mean Schirmer's test value in the healthy contralateral eye was 12.4 +/- 0.4 mm.
- A statistically significant decrease in tear secretion was observed in the eye affected by pterygium.
Conclusions:
- The study concludes that patients with unilateral pterygium exhibit significantly reduced tear secretion in the affected eye.
- This finding suggests a potential link between dry eye and the pathogenesis or progression of pterygium.
- Further investigation is warranted to elucidate the causal relationship and clinical implications.
