Abstract

Purpose

Apply monitoring child's congenital glaucoma, imaging of the optic nerve of adult glaucoma tests: RNFL and analysis of ganglion cells in Optical coherence tomography.

Methods

We studied 30 childrens with congenital glaucoma balanced aged 6 to 18 years whose usual monitoring focuses on visual acuity, intraocular pressure and visual field. Using Zeiss Cirrus HD OCT Spectral Domain, we studied the structure of the optic nerve of these patients (RNFL and ganglion complex) and was compared to that of adults.

Results

The values obtained for young patients with normal visual field are identical to those of an adult an average of 99μm for the RNFL and 85 μm for ganglion cells analysis. For other patients anomalies are consistent with campimétriques deficits observed. Imaging of the optic nerve found the same abnormalities of function and structure of the optic nerve in adults. Thanks to the rapid acquisition of OCT images, this review is implementation easier and earlier than the visual field study in children. OCT allows monitoring of glaucoma patients for several years. However, in children, this monitoring is not carried out in practice common and could serve as an additional tool.

Conclusion

Child's congenital glaucoma requires regular monitoring based on intraocular pressure and when age permits the study of the visual field. the monitoring of these patients can be started earlier with the study of the optic nerve in Oct (RNFL and ganglion cells analysis) to the consistency of results between adults and children. The completion of the visual field is difficult before the age of 8, the feasible before OCT this age allows earlier monitoring of this disease.
