Wy­stę­po­wa­nie krót­ko­wzrocz­no­ści szkol­nej u stu­den­tów me­dy­cy­ny

Introduction
To estimate the frequency and dynamic changes in refractive errors in population of students of medical (MF) and dental (DF) faculties of Pommeranian Medical Academy in Szczecin.

Material and methods
Medical records from ophthalmic examinations performed in 176 medical students (117 females and 59 males) during the 2nd and 4th course of studies were analyzed (2-years long observation).

Results
Refractive error was found in 42% of MF students and 39.5% of DF students on the 2nd course and in 51% and 47% on the 4th course respectively. Myopia was found in 75% of ametropic eyes. In 2 years observation time, there was a statistically significant progression of refracive error in 50% of myopic students (from -2.9 ± 2.3 D to -3.4 ± 1.9D in MF and from -2.0 ± 1.5 to -2.4 ± 1.5D in DF). Myopia developed in 13% of initially emmetropic students.
