From: Rate of central corneal thickness changes in primary angle closure eyes: long-term follow-up results
Comparison of central corneal thickness changes between the trabeculectomy and laser peripheral iridectomy only groups over time. Changes of central corneal thickness (CCT) over the 11 years. The CCT of the trabeculectomy group is lower than that of the laser peripheral iridectomy (PI) only group, which was revealed to be statistically insignificant (P = 0.112).
