Purpose

To determine changes in Meibomian glands and TBUT with prolonged use of face shield versus face mask

Setting

Future center for cornea and refractive surgery, Sohag, Egypt

Methods

200 eyes of 100 subjects aged 18-40 years were included. Exclusion criteria were refractive or lid surgery, autoimmune diseases and contact lens wearers.

Group A (face shield): 80 eyes of 40 subjects.

Group B (face mask): 120 eyes of 60 subjects.

Duration of wear during the last 6 months: 6 hours or more/day, 4 days or more/week.

Outcomes: Meibograde and meiboscore, NIF-BUT and NIAvg-BUT.

Non-contact meibography and Non-contact BUT

Instrument: sirus ocular topographer.

Results

Group A: Meibograde (14% grade 0, 37% grade1, 29% grade 2, 17% grade 3, 3% grade 4). Average meiboscore was 3.2±0.8. NIF-BUT and NIAvg-BUT were 14±2.4 seconds and 12±3.1 seconds respectively.

Group B: Meibograde (4% grade 0, 19% grade1, 34% grade 2, 28% grade 3, 15% grade 4). Average meiboscore was 5.1±0.6. NIF-BUT and NIAvg-BUT were 8±1.8 seconds and 10±2.1 seconds respectively.

Conclusion

Prolonged face mask wear is associated with MGD compared to face shield.
