*Nineteen eyes that did not receive subsequent surgical intervention in the 5-year follow-up period were used in this analysis. Three eyes were missing one or more OCT. Only one eye from each patient was used in this analysis. †P-values refer to comparison with pre-SLT values. Bold values indicate the p-value <0.05.
