Summary

This observational cross-sectional study will assess the impact of hypothyroidism on tear production and tear film stability. Conducted at DHQ Hospital dera ghazi khan over six months, the study will recruit 71 participants aged 20-60 years using a non-probability convenience sampling method. Patients with confirmed hypothyroidism will undergo tear assessment through the Schirmer I test, Tear Breakup Time (TBUT) test, and Ocular Surface Disease Index (OSDI) questionnaire. The Schirmer test will measure tear production, while TBUT will assess tear film stability.

Detailed description

Ocular surface staining and tear osmolarity will further evaluate ocular health. Patients with systemic conditions affecting tear production, such as diabetes or rheumatoid arthritis, will be excluded. The collected data will be analyzed to determine the relationship between hypothyroidism and dry eye symptoms, aiding in better management of ocular health in hypothyroid patients. The study aims to provide valuable insights into the association between thyroid dysfunction and tear film abnormalities.
