Double peak sign on ultrasonography: A new prognostic marker before surgery for white cataract.

ABSTRACT: A mature, hypermature, or white cataract needs posterior segment evaluation before surgery for prognostification. Ultrasonography is the preferred method for this. White cataract or intumescent cataract risks intraoperative capsulorhexis running out leading to devastating complications due to high intralenticular pressure. Altghough sligh-lamp examination before surgery can gives clue regarding fluid pockets under anterior capsule in these types of cataract, fluid in posterior compartment of lens can be detected by ultrasonography. The author here described a new sign, the double peak sign which can predict the high intra-lenticular pressure especially in posterior compartment of the lens. So if it detected before surgery, all precautions can be taken during surgery to prevent complication
