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.

Objective: To evaluate central macular thickness and choroidal thickness in patients with macular edema due to diabetic retinopathy versus controls. Study Design: Cross-sectional comparative study. Place and Duration of Study: Department of Ophthalmology, Lahore General Hospital, Lahore, from Jan to Jul 2018. Methodology: A retrospective data of 100 eyes from 50 patients having with diabetic macular edema associated with diabetic retinopathy was extracted from hospital registry. Additionally, 100 eyes of 50 individuals without any preexisting ocular conditions, comprising a control group was included in the study. Choroidal thickness measurements were made from the posterior edge of the retinal pigment epithelium to the choroid/sclera junction at subfoveal level using optical coherence tomography. Central macular thickness was also measured for all the enrolled patients. Results: One hundred patients fulfilling the inclusion criteria were enrolled in our study. The mean age was 56.27 ± 14.41 years. The mean Central macular thickness of all the patients were reported as 270.49 ± 72.38 μm, while the choroidal thickness was 284.89 ± 96.51 μm. There was statistically significant difference in central macular thickness between both healthy and diabetic retinopathy with diabetic macular edema groups (p=0.001), whereas insignificant difference existed between the two groups forchoroidal thickness (p=0.735). Conclusion: In patients with diabetic macular edema no significant change in choroidal thickness was observed compared with healthy controls, while the thickness of the retina was high in patients with macular edema due to diabetes.

Purpose:  To study the effects of Intra-vitreal injection of Bevacizumab as an adjunct during phacoemulsification in patients with diabetic retinopathy. Study Design:  Quasi experimental study. Methods:  Hundred diabetic patients who were scheduled to undergo phacoemulsification were included in the study. They were equally divided into two groups; Bevacizumab and control group. Complete ocular examination and macular thickness and volume were determined using an OPTOVUE-OCT machine. The patients in the Bevacizumab group were given intra-vitreal injection of 1.25 mg/0.05ml of Bevacizumab at the time of Phacoemulsification. A written ethical approval was obtained and the study was conducted according to principles of declaration of Helsinki. Results:  The bevacizumab group manifested low value of CMT one month post-surgery as compared to the control group (262.2 ± 32.2 and 288.5 ± 54.1, respectively) with P = 0.01. The Total Macular volume, and Best-corrected visual acuity in the two groups showed no significant difference one month after surgery. Amongst the patients who developed postsurgical macular edema, four patients did not possess a positive history for diabetic retinopathy and 3 of them had Non Proliferative Diabetic Retinopathy. We found no significant relationship between the post-surgical macula edema with the presence of mild Non Proliferative Diabetic Retinopathy. (Fisher's test, P = 0.321). Conclusion:  The ocular anti-VEGF therapy substantially reduces macular edema secondary to post-surgical inflammation in diabetic patients. It effectively reduces the central macular thickness although the results are not found to be statistically significant when compared with the control group. Key Words:  Diabetes mellitus; diabetic macular edema; diabetic retinopathy: Bevacizumab.

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 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 the study was to evaluate central corneal thickness in diabetic patients and to compare the results with controls without diabetes mellitus. Sixty-five diabetic patients (65 eyes) constituted the study group, and 50 eyes were from the healthy control group (50 non-diabetic patients). The study group was subdivided into group 1 (no diabetic retinopathy, n = 35), group 2 (mild to moderate nonproliferative diabetic retinopathy, n = 20), and group 3 (proliferative diabetic retinopathy, n = 10). Central corneal thickness measurements in microns were determined using ultrasound pachymetry. The mean central corneal thickness was significantly greater in the study group (567.14 μm ± 14.63 μm) than in the control group (531.14 μm ± 5 μm). In addition, the mean central corneal thickness was found to be greater in group 3 (577 μm ± 12 μm) than in groups 1 (562 μm ± 13 μm) and 2 (566.86 μm ± 15 μm), but the difference did not reach statistical significance. We found that the mean central corneal thickness for diabetic patients was thicker than that of the healthy controls. Thicker central corneas associated with diabetes mellitus should be taken into consideration when obtaining accurate intraocular pressure measurements in diabetics.

Abstract Purpose To investigate the intravitreal and blood Asymmetric dimethylarginine (ADMA) level in diabetic retinopathy (DR). Materials and Methods Twenty eyes of 20 patients with DR with the decision of vitrectomy, and 20 eyes of 20 patients without diabetes as a control group were included in the study. During vitrectomy, vitreous and minimum 3ml peripheral blood samples were taken simultaneously. Serum and vitreous ADMA levels were compared between the two groups. Results The serum ADMA level was higher in the diabetic group compared to the non-diabetic group (p=0,009). However, there was no statistically significant difference between the mean vitreous ADMA levels. There was no correlation between serum and vitreous ADMA levels. Conclusion In patients with diabetic retinopathy, serum ADMA levels increased, but no increase in vitreous ADMA levels was detected.

Background: This study was aimed to compare the effect of laser photocoagulation (LF), intravitreal bevacizumab (IVB) and combined treatments on biomarkers of oxidative stress such as aldehhyde dehidrogenase (ALDH), malondialdehyde (MDA) level, superoxide dismutase (SOD) activities, and vitreal vascular endothelial growth factor (VEGF) on proliferative diabetic retinopathy (DR) patients.Methods: In this single blind randomized clinical trial, 72 eyes from 69 cases of proliferative DR in Cipto Mangunkusumo Hospital between February 2011 - June 2013 were randomized into 4 groups : 1) control (n = 18); 2) LF pre-vitrectomy (n = 18); 3) IVB pre-vitrectomy (n = 18); and 4) combined IVB and LF pre-vitrectomy (n = 18). One-way ANOVA was used to compare oxidative stress parameters in the four groups.Results: There were no statistically significant differences in the average plasma ALDH activity (0.034 ± 0.02; 0.027 ± 0.02; 0.025 ± 0.02; 0.031 ± 0.11 IU/mg protein; p = 0.66), vitreal MDA level (1.661 ± 1.21; 1.557 ± 1.32; 1.717 ± 1.54; 1.501 ± 1.09 nmol/mL; p = 0.96) and SOD activity) (0.403 ± 0.50; 0.210 ± 0.18; 0.399 ± 0.49; 0.273 ± 0.32 U/mL; p = 0.38) among these four groups, respectively. However, the VEGF vitreal level (pg/mL) showed a statistically significant difference (0.356 ± 0.60; 0.393 ± 0.45; 0.150 ± 0.24; 0.069 ± 0.13; p = 0.05). The VEGF level in combination group was five times lower than the control group (p = 0.05).Conclusion: Combined treatments of DR by IVB and LF were correlated with lower vitreal MDA and plasma VEGF level, but did not have any effect on plasma ALDH and vitreal SOD in proliferative DR. Combined treatments with IVB and LF are recommended for the management of proliferative DR patients.

Abstract Background Panretinal photocoagulation treatment (PRP) have been known as a standard treatment for proliferative diabetic retinopathy (PDR) or severe nonproliferative diabetic retinopathy (sNPDR). However, there is no consensus on when PRP should be administrated if anti-VEGF treatment is needed for the concurrent diabetic macular edema (DME). This study is to evaluate the difference between two groups of PRP prior to, or after intravitreal conbercept (IVC) for patients with PDR or sNPDR combined with DME. Methods This was a retrospective study. Fifty-eight eyes with DME secondary to PDR or sNPDR were divided into two groups; the PRP after (PRP-after group), or prior to (PRP-prior group), IVC. Changes in number of IVC injections, best corrected visual acuity (BCVA), and central subfield macular thickness (CSMT) were compared after 4 weeks, 12 weeks, 1 year, and 2 years from the first IVC injection. Results The mean number of injections in PRP-after group was 4.8 (1 year) and 6.4 (2 year), lower than 6.4 (1 year) and 8.5 (2 year) in PRP-prior group (both p = 0.002). There was no significant difference in change in BCVA and CSMT between two groups after each follow-up. Conclusion PRP after IVC requires less injections but also yields similar visual and anatomic outcome comparing with PRP prior to IVC in patients with diabetic retinopathy combined with DME.
