Purpose To investigate the clinical effects and outcomes of intravitreal injection of 4 mg of triamcinolone acetonide (IVTA) after or concomitant with macular laser photocoagulation (MP) for clinically significant macular edema (CSME). Methods Forty-nine eyes of 49 patients with nonproliferative diabetic retinopathy and CSME were randomized into three groups. The eyes in the laser group (n=17), group 1, were subjected to MP 3 weeks after IVTA; the eyes in the IVTA group (n=13), group 2, were subjected to MP, concomitant with IVTA; the eyes in the control group (n=19), group 3, underwent only IVTA application. Visual acuity (VA), fundus fluorescein angiography, and photography were performed in each group. Results In the first group, the mean VA improved from 0.17±0.09 at baseline to 0.28±0.15 (p=0.114) and in the second group, deteriorated from 0.19±0.08 at baseline to 0.14±0.08 at the sixth month (p=0.141), respectively. In Group 3, the mean VA improved from 0.16±0.08 at baseline to 0.28±0.18 (p=0.118) at the end of the follow-up. When VA was compared between the control and study groups, significant difference was detected at the sixth month (p=0.038). Conclusions MP after IVTA improved VA, rather than MP concomitant with IVTA, and only IVTA application for CSME. MP after IVTA may reduce the recurrence of CSME and needs further investigations in a longer period.

Introduction. Diabetic retinopathy is the most common cause of visual loss and blindness in the age group of 20 to 64 years. This study aimed to evaluate the efficacy of oral Losartan adjuvant therapy in combination with intravitreal injection of Bevacizumab in the treatment of diabetic macular edema. Methods. In this randomized clinical trial, 61 eyes of 47 patients with normal blood pressure and diabetic macular edema and nonproliferative diabetic retinopathy were studied. Patients were randomly divided into Losartan (n = 33) and control (n = 28) groups. All patients received 3–6 intravitreal injections of Bevacizumab over 6 months. General examination including blood pressure and glycosylated hemoglobin measurements were performed in all patients. Complete ophthalmologic examination and macular OCT were performed at the first, third, and sixth months of treatment in all patients. Results. The mean age of the patients studied was 57.1 ± 7.4 years and 37.7% of the patients were male. There was no significant difference between the two groups in terms of initial visual acuity, central macular thickness, and frequency of injections. There was no significant difference in visual acuity and central macular thickness between the two groups at the first, third, and sixth months of treatment. Age, frequency of injection, and initial macular thickness less than 450 microns were effective in patients’ final visual acuity. Conclusion. Short-term adjuvant treatment with Losartan in patients with diabetic macular edema and nonproliferative diabetic retinopathy has no greater effect than the standard treatment.

The Early Treatment Diabetic Retinopathy Study (ETDRS) was a randomized clinical trial involving nearly four thousand diabetic patients with early proliferative retinopathy, moderate to severe nonproliferative retinopathy, and/or diabetic macular edema in each eye. This paper (ETDRS report number 9) examined the question of when in the course of diabetic retinopathy it is most effective to initiate photocoagulation therapy. Based on the study findings, the authors recommended that panretinal scatter photocoagulation not be carried out in eyes with mild or moderate nonproliferative diabetic retinopathy; when retinopathy is more severe, however, panretinal scatter photocoagulation usually should not be delayed if the eye has reached the high-risk proliferative stage. Focal treatment should be considered for eyes with macular edema that involves or threatens the center of the macula, preferably before scatter photocoagulation for high-risk proliferative retinopathy becomes urgent.

The Early Treatment Diabetic Retinopathy Study (ETDRS) was a randomized clinical trial involving nearly four thousand diabetic patients with early proliferative retinopathy, moderate to severe nonproliferative retinopathy, and/or diabetic macular edema in each eye. This paper (ETDRS report number 1) describes the findings in the subgroup of eyes in the ETDRS that were identified as having mild to moderate nonproliferative diabetic retinopathy and macular edema. The analysis showed that immediate focal argon laser photocoagulation of “clinically significant” diabetic macular edema substantially reduced the risk of visual loss, increased the chance of visual improvement, decreased the frequency of persistent macular edema, and caused only minor visual field losses. The authors recommended immediate focal argon laser photocoagulation for all eyes with clinically significant macular edema and mild or moderate nonproliferative diabetic retinopathy, regardless of the level of visual acuity.

The purpose of this study was to evaluate the effectiveness of intravitreal ranibizumab (Lucentis, Genentech, South San Francisco, Calif, USA) combined with cataract surgery for the prevention of clinically significant macular edema (CSME) in patients with diabetic retinopathy (DR). This prospective interventional case series included fifty-four eyes of 54 patients with a previous diagnosis of nonproliferative diabetic retinopathy (NPDR) without macular edema preoperatively. Subjects were assigned in a 1 : 1 ratio to receive an intraoperative intravitreal ranibizumab injection (n=27) or not (control group,n=27) associated with standardised phacoemulsification surgery. The main outcome measure was the incidence of CSME one and three months after surgery. One month after surgery the incidence of CSME in the control group was 25.92% and 3.70% in the treatment group and at three months was 22.22% and 3.70%, respectively. Short-term results suggest that intravitreal ranibizumab immediately after phacoemulsification prevents CS ME in patients with NPDR.
