The CLASS Surgical Site Characteristics in a Clinical Grading Scale and Anterior Segment Optical Coherence Tomography: A One-Year Follow-Up

Table 5

Correlation between AS-OCT scleral lake measurements (SL anteroposterior extent, SL height) and intraocular pressure (IOP) in 23 patients presenting clinically successful CLASS at 1 month (1M), 3 months (3M) and 12 months (12M) following the surgery. The correlation coefficient (r) is not significant.
