38 Cases Clinical Analysis Of Children With High Intraocular Pressure

Objective: Discuss the characteristics of children in high intraocular pressure and the related factors, and analysis of children's risk of high intraocular pressure.Methods: We collected 38 cases (64 eyes),age from 5ys to 14ys, who's non-contact intraocular pressure are high of our hospital from March 2010 to February 2011.Besides,we did examinations of diopter, central corneal thickness(CCT), retinal nerve fiber layer(RNFL) and cup/disc(C/D) for them, and analyze their sex, age, eye, diopter, CCT with NCIP.Results: 64 eyes in 38 patients who's age from 5ys to 14ys, mean 11.21ys, NCIP in the range between 21-34mmHg, mean 25.58±2.90mmHg, including 34 eyes in 21 patients of male and 30 eyes in 17 of female, 33eyes of left eye and 31 eyes of right eye. Analysis by t-test, our research find NCIP between sexes, yes are no statistically significant. But ages are significantly different between the NCIP. CCT range from 490 to 623 um, mean 548.69±36.59 um, which 28 eyes' CCT are more than 560um, mean ( 586,.39±14.39) um, 36 eyes' CCT are less than or equal to 560um, mean ( 519.36±15.10 )um. CCT and NCIP was positively correlated. Dioper range from -( 0.25～6.75) D, mean -( 2.66±1.98 )D. Including 37 eyes which are emmetropia and less than -3.00D, 24 eyes are -( 3.00～6.00 )D, 3 eyes >-6.00D. Different degrees of myopia there are differences between the NCIP, especially between the low and moderate myopia are obvious. NCIP in moderate myopia are generally higher than low myopia. During follow-up, 1 patient developed juvenile open angle glaucoma(JOAG), and received local hypotensive therapy. In our research the incidence of glaucoma is 2.63%. 3 cases of intraocular pressure decrease after refractive correction, suggesting that after glasses the ciliary muscle spasm may be reduced, the road of trabecular meshwork has been open, increase aqueous outflow.Conclusions: Children with high intraocular pressure is closely relate to central corneal thickness and myopia. The intraocular pressure in persons with low myopia are less than those with moderate myopia. Juvenile with myopia should check his/her intraocular pressure routinely for early detection of whether the high intraocular pressure and prevent glaucoma.
