Background:
The aim of this study was to quantify and to evaluate changes concerning anterior chamber depth, central corneal thickness and chamber angle width because of altered forces on the eye bulb after eye muscle surgery in children by means of optical coherence tomography.
Patients And Methods:
Over the course of four months, we measured central corneal thickness (CCT), anterior chamber depth (ACD) and chamber angle width at 0 degrees (CW0) and 180 degrees (CW180) in 28 eyes of 28 children, who underwent eye muscle surgery on one horizontal muscle. Measurements were taken preoperatively, one week and four months postoperatively using Visante (TM) OCT (Carl Zeiss, Meditec, Jena). Exclusion criteria were an age under five years at the time of surgery, previous intraocular surgery and other pathological conditions of the anterior segment. The median age at surgery was 6.5 years (range: 7.1, max: 8.9; min: 5.3).
Results:
Mean values taken preoperatively, one week and four months postoperatively were: CCT: 534 +/- 32 microm; 533 +/- 30 microm; 536 +/- 31 microm (p = 0.12); ACD: 2.98 +/- 0.3 mm; 2.97 +/- 0.3 mm; 2.96 +/- 0.4 mm (p = 0.73); CW 0: 38.1 +/- 3.6; 38.9 +/- 4.7; 38.3 +/- 4.7; CW 180: 34.7 +/- 4.2; 35.3 +/- 4.3; 36.2 +/- 5.2; (p = 0.41). The differences between the mean values in all measurement rows were not significant.
Conclusion:
In children who underwent eye muscle surgery on one horizontal muscle this procedure had no significant impact on central corneal thickness, anterior chamber depth and chamber angle width of the operated eyes within a postoperative period of four months.
