Visual loss reversed after treatment of acute bacterial sinusitis

Visual loss is a rare complication of acute bacterial sinusitis (ABS). Very few cases have been reported in the literature. Only two cases of visual loss reversed after treatment of ABS are found in the English-language literature. We present three cases in which significant visual loss was reversed after treatment of ABS. The experience with visual loss associated with ABS is small; therefore, no definitive statement about treatment can be made, However, on the basis of our experience, it appears that immediate surgical drainage with antibiotic therapy may be important in restoring vision.
