Regression analysis on influence factors of orthokeratology controlling juvenile myopia progression

Abstract:

AIM:To explore the influence factors of orthokeratology controlling development of juvenile myopia.

Methods: A retrospective analysis of 86 cases(169 eyes)who performed orthokeratology from November 2012 to November 2013 in our hospital was carried out. Ater 2a treatment, diopter increased > -0.25D as invalid control group(54 eyes), diopter increased ≤ -0.25D as effective control group(115 eyes). The difference of various factors between two groups were compared.

RESULTS: Univariate comparison showed that the two groups had no statistical significance(P>0.05)in terms of gender, whether wear glasses in the past, anterior corneal diameter before treatment, central corneal thickness, intraocular pressure and anterior chamber depth. However, the two groups had statistical significance(P<0.05)in the terms of age, dioptre before trement, corneal curvature, and axial length basis. Logistic regression analysis showed that foundation axial length, age and corneal curvature were in line with regression model(P<0.05), these were independent factors that orthokeratology lens control juvenile myopia development.

CONCLUSION: Independent factors affecting orthokeratology control juvenile myopia development is foundation axial length, age and corneal curvature. For juvenile patients, the longer of foundation axial length, the longer the age, the greater the curvature of cornea, orthokeratology can better control the myopia's development.
