Ethmoidal Sinus Mucocele as a Cause of Acquired Brown Syndrome

lenge. Surgery can lead to iridodialysis, cyclodialysis, and subsequent bleeding [5]. The following steps prevented these complications in the two patients presented here. First, we used a modified Siepser technique for creation of the knot in situ. This type of knot minimizes the force pulling on the iris from the direction of the corneolimbal angle. Second, we used an IOL manipulator to create a counter-force when the needle was passed through the iris. Third, the viscoelastics is inserted in a step-wise manner. This was performed to prevent iris prolapse through the primary incision, which would subsequently trigger a sharp spike in IOP. Finally, the needle was maneuvered extremely gently when passing horizontally through the anterior chamber to as to avoid contact with the lens. This is the first report to describe the adaptation of a modified Siepser slipknot technique to treat symptomatic LPI in phakic eyes.
