Abstract
The comparison of the results of ophthalmometry performed using the Icare tonometer, transpalpebral tonometer TVGD-01, pneumotonometry and Maklakov tonometer in healthy children and patients with congenital glaucoma. We examined 20 children (40 eyes) with compensated congenital glaucoma at the age of 5-17 years, the control group consisted of 43 patients (86 eyes) - healthy children and children with mild myopia. The cornea radius of curvature in children with congenital glaucoma was 8,24±0,08 mm, in healthy children - of 7,68±0,03 mm Hg. Central corneal thickness in 52,5% of patients was 599,20±8,07 pm, 47,5% of patients had 508,90±7,28 pm, while children in the control group had 562,46±4,00 pm. The average intraocular pressure (Po), obtained by tonometry using Icare was 15,3±1,04 mm Hg in children with congenital glaucoma, 18,26±0,46 mm Hg in children of the control group, pneumotonometry was 16,23±2,07 mm Hg and 17,48±0,34 mm Hg respectively. Indicators transpalpebral tonometry (PT) in children with congenital glaucoma - 16,90±0,50 mm Hg, children in the control group - 18,60±0,48 mm Hg, Maklakov tonometry - 18,14±0,58 mm Hg and 18,98±0,24 mm Hg respectively. Positive direct correlation between Icare tonometry and corneal curvature radius (r=0,79) and between central corneal thickness and IOP on Maklakov (r=0,93). A negative correlation between the value of the anteroposterior size of the eye and results transpalpebral tonometry (r=-0,47). Interpretation of intraocular pressure measurementresultsin children with congenital glaucoma should be based on the modified properties of the cornea in these patients.
