Webb7 apr. 2024 · Dry eye is clinically subdivided into two subtypes: aqueous-deficient DED (with decreased tear secretion) and hyperevaporative DED (with increased tear evaporation) [ 15 ]. Medical students are at risk of DED due to the excessive reliance on electronic devices for e-learning and possibly the prolonged use of facemasks. Webb5 jan. 2024 · The tear evaporation rate (TER) test can be used to detect eye dryness and tear film instability, in combination with the other tests [ 37, 38 ]. The test is simple, fast, repeatable, non-invasive, and convenient. Various techniques can be used to determine the TER rate with a normal eye up to 25 g/m 2 h (at a humidity of 30%).
