BACKGROUND
Meibomian Gland Dysfunction (MGD) is widely prevalent condition that is associated with evaporative dry eye disease. Many a times, patients are not symptomatic, so the condition goes unnoticed in early stages.
The aim of the study is to investigate the association of MGD in relation to age, occupation and lid hygiene in rural population.
MATERIALS AND METHODS In our prospective observational study, 100 patients in each case and control group were enrolled and detailed personal history including occupational, medical and drug history was recorded. Symptoms and visual acuity of patients was recorded followed by examination of lids, adnexa, ocular surface and surrounding nasal and paranasal area. MGD was graded as per the quality and expressibility of meibomian gland secretion.
RESULTS Prevalence of MGD increases with advancing age. Chi-square test is suggestive of strong association with increasing age and MGD (x2=58.3; P<0.0001). MGD in rural population is more severe in animal handlers as compared to farmers and other occupations. Chi-square test of association was statistically significant (x2=51.49, P <0.0001).
CONCLUSION
We conclude that prevalence of MGD increases with advancing age and severity of MGD is more in animal handlers as compared to farmers and other occupations. Patient education on correct lid scrubbing and effective lid warming practices must be followed meticulously.
