Abstract

Aim: This research aimed to assess the impact of topical diclofenac Na versus systemic and topical diclofenac Na in pain control at or after trans-scleral diode application
Patients and Method: After institutional board (IRB) review was gained with approval code (MKSU 26-5-21), An investigation involving 37 glaucoma patients whether primary or secondary was carried out in a randomized controlled design. The patients were classified into two groups, group A: individuals undergoing diode application with applying local and systemic diclofenac eye drops. Group B: patients who underwent diode application with applying systemic diclofenac only.
This prospective interventional study was conducted in the period between Jun. 2021 and Dec. 2021 in the ophthalmology department, Kafrelshiekh University Hospital, Kafrelshiekh University, Egypt.
Results: Group A (mean age 54.83±11.79 years) showed significant VAS score reductions at 1 day, 1 week, and 1 month (p<0.001). Both groups exhibited significant VAS score improvements compared to pre-operative levels on 1st-day post-op (p<0.001). The mean 1st day visual acuity differed significantly between groups (p<0.001). Group two demonstrated a more substantial intraocular pressure reduction at 3 months (p<0.01).
Conclusion: Combined local and systemic diclofenac administration was associated with more pain control and should be used frequently in routine practice.
