This randomized controlled trial evaluated the effects of subthreshold micropulse laser photocoagulation (SMLP) versus conventional subthreshold laser photocoagulation (SLP) in 66 eyes of 33 patients with clinically significant diabetic macular edema (CSME). The study found that while both treatments were similarly effective in terms of visual acuity and other measures, SMLP led to a significant reduction in central macular thickness (CMT) earlier at 3 months compared to SLP at 6 months.
Key findings
- No significant difference in BCVA, CMT, or macular sensitivity between SMLP and SLP (all p > 0.05).
- SMLP showed significant CMT reduction at month 3, while SLP at month 6 (all p < 0.05).
Why it matters
Understanding the comparative effectiveness and safety of SMLP and SLP is crucial for optimizing treatment strategies in diabetic macular edema, potentially leading to improved patient outcomes with less retinal damage.
