Comparative Study
Comparison of the scanning peripheral anterior chamber depth analyzer and the modified van Herick grading system in the assessment of angle closure.
To compare the performance of the scanning peripheral anterior chamber depth analyzer (SPAC) and the modified van Herick grading system in the assessment of angle closure, using gonioscopy as the reference standard. ⋯ The SPAC correlated well with the modified van Herick system in grading peripheral ACD. However, the SPAC appeared to overestimate the proportion of eyes with narrow angles relative to gonioscopy and the modified van Herick grading system.

To study the association of annual surgeon volume of cataract procedures with the risk of postoperative adverse events. ⋯ Selected adverse event rates for surgeons performing more than 50 cataract surgeries per year are low. There is a volume-outcomes relationship for cataract surgery, and this relationship persists even for very high-volume surgeons.
