Abstract
Abstract
Background
The purpose of this study was to compare the impact of intravitreal dexamethasone (DEX) implant during a 12-month period in nondiabetic and diabetic patients without diabetic retinopathy (DR) as a treatment for refractory pseudophakic cystoid macular edema (PCME) following prior treatment with topical nepafenac 0.1% and prednisolone 1%.
Methods
Forty-two consecutive medical records of patients diagnosed with PCME after uneventful cataract surgery were included. The outcomes measured included best corrected visual acuity (BCVA) and central foveal thickness (CFT). Linear regression analysis was statistically applied.
Results
Following topical treatment, nondiabetic and diabetic subjects presented a mean ± SD gain of − 0.11 ± 0.11 and − 0.18 ± 0.11 BCVA logMAR and a CFT reduction of − 43.42 ± 53.66 µm and − 58.76 ± 36.28 µm, respectively. The mean BCVA gain at month 12 subsequent to DEX implantation was − 0.35 ± 0.17 in nondiabetic (p < 0.001) and − 0.55 ± 0.26 in diabetic patients (p < 0.001), with CFT reductions of − 195.71 ± 93.23 µm (p < 0.001) and − 260.81 ± 198.69 µm (p < 0.001), respectively. Patients who responded with better VA after topical treatment presented better visual outcomes at month 12 following DEX implantation (r2 = 0.46; rho = − 0.71, p < 0.01).
Conclusion
Nondiabetic and diabetic patients without DR demonstrated similar results after DEX implant after combined topical therapy, suggesting that selected diabetic patients may have a response comparable to that of nondiabetic patients with PCME.
