“…Wygnanski-Jaffe and Barequet21 reported nine congenital glaucoma cases with thinner CCT in the eye with the more severe glaucomatous damage in bilateral cases or in the glaucomatous eye compared with the normal fellow eye in unilateral glaucoma cases. These findings were explained by the corneal stretching and/or scarring.…”

PurposeStudying the role of ultrasound biomicroscopy (UBM) in detection of anterior segment changes in infants with primary congenital glaucoma (PCG).MethodsCross-sectional study that included 25 eyes of 15 patients suffering from PCG and a control group of 15 eyes of ten age- and sex-matched participants. Diagnosis of PCG was based on clinical data (intraocular pressure, corneal diameter, fundus examination and amplitude-modulation scan measurement of axial length). UBM examination was done for all participants for measurement of central corneal thickness, anterior chamber depth, lens thickness, iris thickness (measured 2 mm from the iris root and again at the thickest point near the pupil), zonular length, posterior chamber depth, and angle of anterior chamber. Qualitative evaluation was done for abnormal angle membranes, iris insertion level, and ciliary processes position and configuration.ResultsMean age ± standard deviation was 10.32±3.59 months in the study group and 14.54±5.9 months in the control group. The central corneal thickness, anterior chamber depth, zonular length, and angle of anterior chamber were significantly larger in the study group than in the control group, with mean values 700±190 μm, 3.55±0.32 mm, 1.02±0.15 mm, and 58.47°±5.57°, respectively. The posterior chamber depth had a mean of 0.33±0.06 mm, which was significantly smaller than that of the control group. In the study group, the mean iris thickness 2 mm from the iris root was 0.32±0.04 mm, the mean iris thickness at the thickest point near the pupil was 0.38±0.08 mm, and the mean lens thickness was 3.32±0.18 mm. These three parameters were smaller than the control group but the difference was insignificant. Loss of normal iris configuration was detected in all eyes of the study group. Anterior iris insertion was detected in 56% of the eyes in the study group, and abnormal angle membrane was found in 12%.ConclusionUBM is a useful tool for detection of anterior segment changes in PCG, which is helpful especially in cases with opaque cornea or cases with borderline clinical findings.

“…Pachymetry measurements have been made in children with congenital glaucoma and in patients with congenital cataracts. The CCT was found to be significantly thinner in nine eyes of patients with congenital glaucoma compared with the normal eye (mean, 57 mm thinner) [10]. This would mean that the measured IOP could underrepresent the true IOP by 2-3 mmHg.…”

“…Большинство авторов, отмечая это обстоятельство, вместе с тем сообщают, что еди-ное мнение по поводу динамики центральной тол-щины роговицы при врождённой глаукоме пока отсутствует [13,16,25,26,30,36,40,44,54,56,57]. Более подробно эти сведения рассмотре-ны ниже.…”

“…В частности, T. WygnanskiJaffe (2006) отмечает, что ЦТР у детей с врож-дённой глаукомой ниже (522,3 ± 65,2 мкм) по сравнению с их здоровыми сверстниками (579,7 ± 44,5 мкм) [57]. Аналогичный результат был получен S. Guigou et al (2008), исследо-вавшими 69 глаз детей с врождённой глаукомой в возрасте от 3 до 18 лет (519 ± 34 мкм -в ис-следуемой группе и 529 ± 32 мкм -в контроль-ной).…”

This review discusses the results of various studies conducted in recent years on the comparison of modern methods of measuring intraocular pressure (IOP) in children: pneumotonometry, Maklakov applanation tonometry, and tonometry using Perkins tonometer, Goldmann tonometer, Icare tonometer, Ocular Response Analyzer, TonoPen handheld tonometer, transpalpebral tonometer TIOP01, or a dynamic contour Pascal tonometer. This study discusses the advantages and disadvantages of different methods of measurement of IOP in children, including the evaluation of patients with fibrous lens capsules that might affect the measurement of IOP and an analysis of the characteristics of evaluation of IOP in children with congenital glaucoma.

Central Corneal Thickness in Congenital Glaucoma

Abstract: CCT was significantly thinner in glaucomatous eyes than in normal fellow eyes in phakic children with congenital glaucoma. This finding may be another confounding factor when measuring IOP in these patients.
