Van Herick Test is used for:
Van Herick's method Measures anterior chamber depth with a slit lamp, focus at peripheral cornea near limbus at an angle of 60 deg It Compares anterior chamber depth with corneal thickness. Van Herick's Grading Grade 4 PAC >= CT Grade 3 PAC = 1/4 to 1/2 of CT Grade 2 PAC = 1/4 of CT Grade 1 PAC < 1/4 of CT CT - Corneal thickness PAC - Peripheral anterior chamber depth Grade 4 means likelihood of angle closure is rare
