PURPOSE: To study the change of corneal birefringence at different pressures in vitro to determine whether corneal birefringence changes along with pressure. METHODS: The pattern of corneal birefringence was recorded at different intraocular pressures. The pressure differences were 0.10, 0.50 and 1.00 mm Hg, respectively. To compare the pattern sequence at two pressure values, a nonpaired t test was performed. RESULTS: Statistical analysis indicates that the difference of the corneal birefringence is significant when the pressure difference was more than 0.50 mm Hg in polarized light. CONCLUSION: The results of corneal photoelasticity in vitro demonstrate that the change in pressure on the cornea leads to a change in corneal birefringence. |
