<prompt> Van Herick Test is used for:Measuring cells and flareMeasuring anterior chamber depthMeasuring angleMeasuring anterior chamber volume  <response>: Van Hericks 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 Hericks Grading Grade 4 PAC CT Grade 3 PAC 14 to 12 of CT Grade 2 PAC 14 of CT Grade 1 PAC 14 of CT CT - Corneal thickness PAC - Peripheral anterior chamber depth Grade 4 means likelihood of angle closure is rare
