Hodges JS, Marcus S, Page E. It's not a tumor, it's a cataract! rapid myopic progression and diplopia secondary to the formation of an oil-drop cataract. Mil Med. 2013;178(3):e372-5.
Oil-drop cataracts are detrimental to patients because of their capacity to cause rapid, and often unexplained, myopic progression with concomitant diplopia complaints. When not properly identified, they can lead to costly and unnecessary workups and referrals. Early diagnosis is important but unfortunately is often difficult because of the subtle nature in which these cataracts present, resulting in under-recognition by clinicians. This case report and discussion will focus on ways to assist the practitioner in diagnosing oil-drop cataracts to ensure appropriate management of the troublesome symptoms affected patients confront.
