Scanning laser tomography in the diagnosis of juvenile glaucoma]

The aim of our research was to evaluate the optic nerve head parameters of children with juvenile glaucoma with the scanning laser ophthalmoscope from Laser Diagnostic Technologies Inc. The material consisted of 46 eyes of 25 children aged from 7 to 18 years. There were 18 glaucomatous eyes (I group) and 28 eyes without glaucoma (II group) as a control group. The three examinations were repeated every three months. Mean values of Vol. B in the glaucomatous group were -0.327 +/- 0.098, first visit; -0.390 +/- 0.130, second visit; 0.344 +/- 0.096 mm3, third visit. These values in the control group were--0.234 +/- 0.73; -0.224 +/- 0.071; -0.252 +/- 0.069 mm3. The difference was statistically significant. Mean values of Volume A were significantly lower in the I group: 0.216 +/- 0.034, 0.207 +/- 0.033, 0.203 +/- 0.030 mm3 than in the II group: 0.269 +/- 0.039, 0.283 +/- 0.032, 0.271 +/- 0.042 mm3. CD ratio was higher in the glaucomatous eyes: 0.447 +/- 0.080; 0.491 +/- 0.069; 0.484 +/- 0.074 in comparison with the control group: 0.376 +/- 0.060; 0.368 +/- 0.067; 0.399 +/- 0.056. It was significant difference. More changes of biomorphometric parameters of the optic nerve head were observed in the glaucomatous group during follow-up period. The role of laser scanning ophthalmoscopic tomography is very important in the diagnosis of early forms of juvenile glaucoma in the youth.
