Patients who showed persistent DME after receiving at least six doses of anti-VEGF agents for DME treatment were included.Results: The study population consisted of 72 participants (29 females, 43 males) having an average age of 66 years. All patients had best-corrected visual acuity (BCVA) less than 0.7 (6/9) and SD-OCT documented center-involved DME. The study results showed that the average baseline BCVA improved from 0.205± 0.1 before DEX injection to 0.358± 0.1 at 3 months post-injection (p< 0.0001). The central mean thickness (CMT) showed significant improvement also (539.347± 132.402 to 379.041± 99.430, p< 0.0001). There was a mean of 3 mmHg increase in intraocular pressure at 3 months post-injection (p< 0.0001), however, only 4% of patients required medical treatment. Other inflammatory biomarkers in OCT, such as intraretinal hyper-reflective dots (HRD), showed significant improvement also (23.67± 16 to 14.83± 13, p< 0.0001). No other significant safety concerns were noticed.Conclusion: A single DEX injection showed significant clinical and anatomical improvement in DME cases that are persistent after anti-VEGF treatment in our sample, with an excellent safety profile. In case of supply shortage of intravitreal injections, which occurs frequently at our center, a single DEX injection may be utilized as an effective DME therapy. Further research is mandated to identify clinical response in a larger sample and more frequent injections.Keywords: diabetic macular edema, dexamethasone, anti-VEGF, Ozurdex, Jordan
