Intravitreal Triamcinolone and Biomarkers in Rhegmatogenous Retinal Detachment

This prospective, randomized, controlled clinical study evaluates the effects of preoperative intravitreal triamcinolone acetonide (TA) on growth factors and inflammatory mediators in patients with rhegmatogenous retinal detachment (RRD) and proliferative vitreoretinopathy (PVR). Participants are assigned to either an intervention group receiving a 2-mg intravitreal injection of TA 5-7 days before vitrectomy or a control group receiving standard surgical treatment. The study evaluates TGF-β2, TGF-β3, MMP-2, and MMP-9 levels in aqueous humor and vitreous, macrophage cell counts and inflammatory activity in vitreous, subretinal fluid optical density assessed by optical coherence tomography, and vessel diameter index assessed by optical coherence tomography angiography after surgery.
