Abstract Details

Purpose:

To compare macular thickness (MT) and subfoveal choroidal thickness (SFCT) after cataract surgery in diabetic patients using spectral domain optical coherence tomography (SD-OCT)

Setting:

Ophthalmology Department, University of Siena, Italy

Methods:

This prospective cohort study included 40 eyes with mild-moderate nonproliferative diabetic retinopathy (NPDR) without macular edema that underwent uncomplicated cataract surgery divided in 2 groups according to post-operative treatment. Patients were randomized to receive topical nonsteroidal antiinflammatory drug (NSAID) and steroidal treatment (group 1) or topical steroidal drug alone (group 2) for 6 weeks after phacoemulsification. Before surgery and at 1- and 3-month postoperative visits, all patients underwent SD-OCT with enhanced depth imaging protocol. The mean MT and the SFCT were measured by the same operator.

Results:

The 20 eyes treated with NSAIDs and steroids showed a reduction on MT and SFCT compared with the 20 eyes of group 2 at all follow-up visits, but the difference was statistically significant (p=.03) only at 1 month follow-up. Changes in SFCT did not correlate with changes in macular thickness.

Conclusions:

Diabetic eyes treated with NSAIDs and steroids have a low risk of increased MT and SFCT on SD-OCT after cataract surgery, Treatment to prevent this might improve early outcomes in diabetic patients. FINANCIAL INTEREST: NONE
