Comparative Outcomes of Standard Perioperative Eye Drops, Intravitreal Triamcinolone Acetonide-Moxifloxacin, and Intracameral Dexamethasone-Moxifloxacin-Ketorolac in Cataract Surgery

Background: Since the advent of cataract surgery, topical eye drops have been the mainstay of postoperative prophylaxis and treatment. Due to factors such as high expenses and poor patient compliance, there has been a growing interest and acceptance of “dropless” alternatives. The purpose of this study is to compare the effectiveness of intravitreal triamcinolone acetonide-moxifloxacin and intracameral dexamethasone-moxifloxacin-ketorolac to a standard eye drop regimen in controlling postoperative inflammation, corneal edema, and intraocular pressure (IOP) among cataract patients.Methods: A retrospective longitudinal comparative study among 619 consecutive eyes receiving either a standard eye drop regimen, intraoperative triamcinolone acetonide-moxifloxacin or dexamethasone-moxifloxacin-ketorolac was performed between October 2016 and December 2020. Primary endpoints at postoperative day one (POD1), week one (POW1), and month one (POM1) included corneal edema, anterior chamber inflammation (ACI), and IOP.Results: Throughout the postoperative time points, there were no significant differences in corneal edema between intravitreal triamcinolone acetonide-moxifloxacin versus the standard eye drop therapy (OR [95%CI]: 1.09 [0.82, 1.45], P = .54) and intracameral dexamethasone-moxifloxacin-ketorolac versus the standard eye drop treatment (OR [95% CI]: 1.22 [0.89, 1.67], P = .22). The postoperative ACI severity was lower in the dexamethasone-moxifloxacin-ketorolac group compared to the triamcinolone acetonide-moxifloxacin group by 35% on postoperative day 1 (P = .01). The differences at subsequent postoperative time points were not statistically significant (P = .27 and P = 1.00 for POW1 and POM1 respectively). IOP at POM1 follow up visit was statistically significantly higher for the triamcinolone acetonide-moxifloxacin group [mean (±SD): 15.64 (4.26)] compared to the dexamethasone-moxifloxacin-ketorolac [mean (±SD): 14.16 (4.02)] (P < .01). There was no statistical difference in rates of CME (P = .16) and there were no cases of endophthalmitis.Conclusions: Intravitreal triamcinolone acetonide-moxifloxacin and intracameral dexamethasone-moxifloxacin-ketorolac demonstrate similar levels of efficacy to a standard eye drop regimen after cataract surgery. This study reinforces them as viable alternatives to traditional postoperative drops.

Long-term outcomes of administration of intravitreal triamcinolone acetonide after posterior vitreous detachment during pars plana vitrectomy for proliferative diabetic retinopathy

AimTo evaluate the long-term outcomes of intravitreal triamcinolone acetonide (TA) administration after posterior vitreous detachment (PVD) during pars plana vitrectomy (PPV) for patients with proliferative diabetic retinopathy (PDR).MethodsA total of 189 eyes (152 patients) who underwent PPV for severe PDR were reviewed. Intravitreal injection of TA (IVTA) was administered during PPV in 118 eyes (PPV+IVTA group), and 71 eyes did not receive IVTA (PPV group). Immediately after PVD, when most of the vitreous and proliferative membranes were removed, 0.1 mL TA (40 mg/mL) was injected into the vitreous cavity in the PPV+IVTA group. All patients were followed-up for least 12 months. Visual outcomes and postoperative complications were recorded and compared between the two groups.ResultsIVTA was helpful for proliferative membrane peeling and haemostasis during PPV. In the PPV+IVTA group, best-corrected visual acuity had significantly improved and the intraocular pressure was controlled well during the follow-up. The incidence of early recurrent vitreous haemorrhage after PPV was significantly lower in the PPV+IVTA group (1.7%) than in the PPV group (9.9%) (p=0.028).ConclusionThe administration of IVTA after PVD during PPV can effectively improve the final visual outcomes and prevent postoperative complications in patients with severe PDR.

EFFECT OF INTRAVITREAL TRIAMCINOLONE ACETONIDE IN REFRACTORY DIABETIC MACULAR EDEMA

Objective: To investigate the effects of intravitreal triamcinolone for refractory diabetic maculopathy after 03 unsuccessful intravitreal bevacizumab injections. Study Design: Prospective observational study. Place and Duration of Study: Retina department of Al-Shifa Trust Eye Hospital Rawalpindi, from Jun 2016 to Jul 2017. Methodology: Total 35 eyes of 35 patients who were diagnosed with diabetic maculopathy and having history of minimum three intravitreal Bevacizumab injections were included. Detailed eye examinations included visual acuity, anterior and posterior segment examination and intraocular pressure measurement was performed in all patients. Central macular thickness was also measured. Then intravitreal triamcinolone was administered to eyes by principal researcher (Ophthalmologist). After one month, follow up examination of patient’s eyes was done to assess the effects of injection. Results: Majority of the participants were males 19 (55%) in this research. There was statistically significant difference between means of intra ocular pressure (mean difference= 4.30 ± 5.41), Visual acuity (mean difference=2.8 ± 2.4) and central macular thickness (mean difference = 236.4 ± 13) pre and post injection was found (p-value<0.05). Conclusion: There was statistically significant difference of central macular thickness and visual acuity, pre and post intravitreal triamcinolone acetonide injection was found.

Comparison of Safety and Efficacy of Grid Laser Versus Combination of Sequential Intravitreal Triamcinolone Acetonide and Grid Laser in Treatment of Diabetic Macular Oedema - Randomized Open Label Study, Bangalore, Karnataka

BACKGROUND The reported prevalence of diabetic retinopathy in diabetics is around 40 %. Diabetic macular oedema (DME) is defined as macular thickening resulting from diabetic retinopathy, due to leakage from micro aneurysms, or from a diffuse leakage of hyper permeable capillaries. Intravitreal injection of triamcinolone acetonide (IVTA) has gained considerable interest and clinical use because it often has beneficial effect on retinal thickening in DME. The synergistic action of IVTA and laser photocoagulation might increase and prolong the beneficial effects of IVTA in reducing ME. Hence the need for a study to compare efficacies of grid laser, and combination of sequential IVTA and grid laser in treating patients with DME. We wanted to evaluate functional and morphological outcome of grid laser versus combination of sequential intravitreal triamcinolone acetonide and grid laser in treatment of diabetic macular oedema. METHODS The study included 62 eyes with DME. There were 31 eyes which received grid laser photocoagulation (group 1) and 31 eyes which received grid laser photocoagulation following IVTA (group 2) and visual acuity, CMT on OCT was compared at baseline and after day 1, 1st week, 4th week and 12th week. Outcome and comparative efficacies were evaluated. RESULTS Our study shows reduced macular thickness and improved visual acuity in group 2 compared to group 1 in all follow ups. On intragroup analysis, we found a significant reduction in CMT in both groups at 1 week, 4 weeks and 12 weeks as compared to baseline. In our study we also compared CMT between group 1 and group 2 which did not show significant difference at baseline. But, difference in CMT from baseline at each follow up which is at 1 week, 4 weeks and 12 weeks between two groups showed more reduction in CMT in group 2 compared to group 1. CONCLUSIONS There was a significant reduction in CMT in all the follow ups of both groups, but group 2 had more reduction in CMT compared to group 1. The synergistic action of IVTA and laser photocoagulation might increase and prolong the beneficial effect of IVTA in reducing ME. This study found evidence of synergistic effects of IVTA and laser photocoagulation in DME in terms of improving visual acuity and in reducing CMT compared to grid laser alone and should be tried as a modality of treatment in DME.

Adjunctive Intravitreal Triamcinolone Acetonide for Exudative Retinal Detachment in Coats Disease

Purpose: This work aims to assess the value of intravitreal triamcinolone acetonide (IVTA) as an adjunctive therapy in advanced Coats disease with exudative retinal detachment (ERD). Methods: A retrospective review was conducted of patients with Coats disease stage 3 or higher who received IVTA to decrease subretinal fluid (SRF), facilitate retinal ablative therapy, and avoid surgical drainage. Primary outcomes were SRF resolution and avoidance of surgical SRF drainage. Results: Seventeen eyes of 17 patients (mean, [SD] age, 3.9 [3.4] years) met the inclusion criteria. ERD configuration was bullous in 7 and shallow in 10 eyes. Following a single IVTA injection, ablative therapy was achieved after a mean (SD) of 2.1 (3.0) weeks. Complete SRF resolution was observed in 13 eyes (76.4%) after a mean of 1.3 IVTA injections and a mean of 2 (SD, 1.27) laser sessions, and none of these eyes required SRF drainage up to last follow-up (mean [SD], 50.5 [26.24] months). In 4 eyes with bullous ERD at presentation, SRF persisted ( P = .015) despite additional measures including surgical drainage. Final visual acuity ranged from 20/100 to no light perception. Cataract developed in 12 of the 17 eyes (70.5%). None developed an increase in intraocular pressure at final follow-up. Conclusions: IVTA injection can be a helpful adjunctive modality to address SRF in advanced Coats disease. It may obviate the need to surgically drain SRF to effectively treat the condition, particularly when the ERD is not highly bullous.

Efficacy of Intravitreal Triamcinolone Acetonide in the Treatment of Macular Oedema in Retinal Vein Occlusion Refractory to Anti-VEGF Therapy - A Prospective Interventional Study from a Tertiary Care Centre in Eastern India

BACKGROUND Macular oedema due to retinal vein occlusion can be refractory to treatment with anti-vascular endothelial growth factor agents in some patients. We wanted to evaluate the efficacy of single dose of intravitreal triamcinolone acetonide in the treatment of macular oedema due to retinal vein occlusion, which is refractory to anti-vascular endothelial growth factor agents. METHODS 32 patients with refractory macular oedema were included in this prospective, interventional, comparative study. 20 patients were included in the study group and received 4 mg / 0.1 ml of intravitreal triamcinolone acetonide. 12 patients in control group did not receive any treatment. Best corrected visual acuity (BCVA) and central foveal thickness (CFT) were assessed in each group at 1 week, 1 month, 2 months and 3 months following injection. RESULTS Mean BCVA in study group improved from 1.36 ± 0.33 logarithm of minimum angle of resolution (LogMAR) at baseline to 0.94 ± 0.49 LogMAR at the end of 3 months. Mean CFT at baseline and 3 months was 498.65 ± 90.64 and 331 ± 100.57 microns respectively in the study group. The mean baseline BCVA and CFT in the control group was 1.19 ± 0.43 LogMAR and 428.33 ± 101.75 microns respectively. Mean BCVA and CFT at the end of 3 months was 1.16 ± 0.45 LogMAR and 424.75 ± 98.75 microns respectively. Change in mean BCVA and CFT at baseline and at the end of 3 months was found to be statistically significant (P = 0.000) between the 2 groups. There was increase in macular oedema in the study patients after the 2nd month following injection leading to slight worsening of visual acuity. CONCLUSIONS Intravitreal triamcinolone acetonide is an option in the treatment of macular oedema due to retinal vein occlusion refractory to anti-vascular endothelial growth factor agents. However, the efficacy of a single injection is short lived. Multiple injections might be needed to maintain the visual gains.
