Abstract
Purpose: :
To determine the prevalence of angiographic cystoid macular edema (CME) in patients with clinically significant diabetic macular edema (CSME) and investigate the impact of CME on visual acuity.
Methods: :
Retrospective review of the medical and photographic records of patients undergoing fluorescein angiography following the diagnosis of CSME in the Penn State Department of Ophthalmology.
Results: :
The medical and photographic records of 278 patients with CSME were evaluated. Angiographic CME was detected in 43% of eyes with CSME. Patients with CME were 2.31 times more likely to have reduced visual acuity compared to patients without CME (p–value < 0.0001). The role of cataract surgery in these patients was not statistically significant.
Conclusions: :
Angiographic CME is commonly present in patients with CSME. The presence of CME is associated with reduced visual acuity compared to patients without CME.
