A patient is referred to you by an outside ophthalmologist.  The patient recently underwent a successful cataract surgery to remove a dense white cataract.  Unfortunately, two months after surgery, the patient’s best refracted visual acuity is still 20/400 despite a totally normal examination of the anterior segment.  The outside ophthalmologist wants your opinion on what is limiting the patient’s vision. On exam, you see the above and order an OCT.

Which of the following most likely explains the patient’s limited visual acuity?

a. chronic cystoid macular edema b. retained lens material c. macular hole   d. clinically significant macular edema from uncontrolled diabetes
