Abstract
- To investigate of lacrimal punctal size in normal korean adults, we measured diameter and area of punctum and punctal papilla according to sex and age group using slit lamp photography in 120 persons, 120 eyes. In upper eyelid, the average diameter and area of lacrimal punctum were 0.57+/-0.2mmxo.29+/-0.1mm, 0.13+/-0.07mm2 andthe average diameter and area of punctal papilla were 1.34+/-0.37mmx0.89+/-0.24mm, 0.98+/-0.53mm2. In lower eyelid, the average diameter and area of lacrimal punctum were 0.61+/-0.17mmx0.3+/-0.1mm, 0.15+/-0.08mm2 and the average diameter and area of punctal papilla were 1.46+/-0.32mmx0.99+/-0.19mm, 1.15+/-0.4mm2. In size difference between lacrimal punctum, lower punctum was larger than upper punctum, but not statistically significant. In size difference between punctal papilla, lower papilla was significantly larger than upper papilla. There is no difference in punctal and papilla size between male and female. The size distribution of punctum was related to age, but size distribution of papilla was not.
