Purpose: We compared the efficacy of sub-Tenon triamcinolone acetonide (STTA) to intravitreal triamcinolone aceto-nide (IVTA) injections during cataract surgery (CS) for patients with diabetic macular edema (DME).
Methods: The medical records of 33 eyes (26 patients) with DME which had undergone CS with STTA were compared to those of 34 eyes (27 patients) with DME which had undergone CS with IVTA. Central foveal thickness and best-corrected visual acuity (BCVA) were measured at the baseline and 1, 3, and 6 months after the surgery.
Results: The BCVAs after STTA and IVTA were significantly improved at 3 and 6 months. Thirteen eyes in the IVTA group and 21 eyes in the STTA group required other therapies (p < 0.05). One case developed intraocular pressure elevation after IVTA and underwent selective la ser trabeculoplasty.
Conclusions: Ophthalmologists should consider the merits and demerits of IVTA and STTA for DME treatment after CS.

Department of Ophthalmology, Slovak Medical University and University Hospital in Bratislava, Antolska 11, 851 07, Bratislava, Slovakia.
Introduction: This study was performed to compare the efficacy and safety of PreserFlo MicroShunt (PMS) implantation with mitomycin C (MMC) applied by sub-tenon injection versus conventional application by MMC-soaked sponges.
Methods: This retrospective, 1-year cohort study included 100 eyes of 100 patients with glaucoma who underwent PMS implantation with MMC (0.4 mg/ml) delivered either by sub-tenon injection (50 eyes) or via soaked sponges (50 eyes).

Article Synopsis
- The study aimed to evaluate the safety and effectiveness of two anesthesia methods—sub-Tenon and subconjunctival—in small-incision cataract surgery for patients with hard-grade cataracts.
- A total of 196 eyes were included in the research, with no significant differences in pain levels, surgical times, or complications between the two anesthesia groups.
- The findings concluded that both anesthesia techniques are safe and effective for the surgery, suggesting that the choice should be based on the surgeon's preference.
Effect of aflibercept combined with triamcinolone acetonide on aqueous humor growth factor and inflammatory mediators in diabetic macular edema.

Aim: To investigate the efficacy of aflibercept combined with sub-tenon injection of triamcinolone acetonide (TA) in treating diabetic macular edema (DME) and to examine changes in growth factors and inflammatory mediator levels in aqueous humor after injection.
Methods: Totally 67 DME patients (67 eyes) and 30 cataract patients (32 eyes) were enrolled as the DME group and the control group, respectively. The DME group was divided into the aflibercept group (34 cases) and the aflibercept combined with TA group (combined group, 33 cases).
Background: Recently, trabeculectomy with mitomycin C (MMC) where MMC is applied by injection into the Tenon layer has attracted close attention. However, the data on efficacy and safety of this technique is still limited and more clinical studies are needed. Therefore, the work is aimed at comprehensive evaluation of the effectiveness of trabeculectomy using MMC applied by intra-Tenon injection.
