[Research of myopia development in children with self-regression of retinopathy of prematurity and in children with regression after cryotherapy].
OBJECTIVE
The aim of the paper is to estimate the influence of self-regression of retinopathy of prematurity (ROP) and regression after cryotherapy for development of axial myopia in premature babies.


METHODS
The researches concerned 4 groups of premature babies in the 6th, 12th and 24th month of life. Group 1--without ROP, group 2--with self-regression of ROP, group 3--with regression of ROP after cryotherapy and group 4--with one eye with self-regression of ROP and second eye with regression after cryotherapy.


RESULTS
In the 6th and 24th month of life mean axial length of eyeball in children from group 3 was statistically significantly higher than mean axial length of eyeball in children from group 1 and 2. In the 12th month of life mean axial length of eyeball in children from group 3 was statistically significantly higher than mean axial length of eyeball in children from group 1. In group 4 mean axial length of eyeball with regression of ROP after cryotherapy was statistically significantly higher than mean axial length of eyeball with self-regression of ROP.


CONCLUSIONS
Self-regression of ROP and regression of ROP after cryotherapy may cause development of axial myopia in premature babies.
