Background: The objective of the study was to examine the effect of long-term glycemic control, as measured by glycated hemoglobin levels (HbA1C), on the onset and progression of diabetic retinopathy (DR) and diabetic macular edema (DME) over a period of 10 years.Methods: Patients who were diagnosed to have type 2 diabetes mellitus participated in this cross-sectional observational study. Duration of onset of diabetes and the glycemic control status were analyzed. Fasting and postprandial blood sugar levels and HbA1C levels were tested for every participant. Diabetic retinopathy was graded as per the ETDRS guidelines using stereoscopic fundus photographs. In addition to the clinical evaluation, optical coherence tomography was done to confirm the presence of DME.Results: A total of 212 diabetic patients were enrolled in this study. One sixty-four patients (78.1%) had DR, out of which 71 patients (43.3%) had mild non proliferative diabetic retinopathy (NPDR), 42 patients (25.6%) had moderate NPDR, 31 patients (18.9%) had severe NPDR, and 20 (12.2%) had proliferative diabetic retinopathy (PDR). Fifty-nine patients with DR (36%) had DME. Duration of diabetes (14.62±6.18 vs 9.72±3.68 years, p<0.001), higher fasting blood glucose (176.79±59.13 vs 138.46±49.44 mg/dl, p<0.001) and higher HbA1c levels (8.21±1.38 vs 7.48±1.25 %, p=0.002) were significantly associated with DR.Conclusions: The stage of diabetic retinopathy rather than metabolic status is a strong predictive factor for the development of diabetic macular edema.

Introduction. Diabetic retinopathy remains the leading cause of visual disability and blindness among professionally active adults in economically developed societies, which is of particular concern because the prevalence and incidence of diabetes mellitus is expected to increase sharply during the next decade. There are several known factors responsible for the development of diabetic retinopathy, duration of disease and blood sugar level being the most important ones. Material and Methods. Prospective study of 280 diabetic patients (diabetes mellitus type 2) divided into 3 groups according to the duration of diabetes mellitus. All diabetic patients underwent complete ophthalmological examination in artificial mydriasis and optic coherence tomography. A full medical history included patient age, the time elapsed from diabetes diagnosis, current treatment of diabetes, presence of hypertension and glycemic control assessed by glycosylated hemoglobin measurement. Results. The mean age of patients was 63.5 years (SD?6.5, range 57-70 years). Mean duration of diabetes was 7.3 years in group I, 12.4 years in group II and 17.2 years in group III. The average value of glycosylated hemoglobin was 6.58% in the group I, 7.64% in the group II and 8.29% in the third group of patients. No statistically significant difference in intraocular pressure and the level of blood pressure were found among groups. Cataract was present in 104 patients (37.1%). Complications related to diabetes among all patients included in our study were: nonproliferative diabetic retinopathy in 48.5%, proliferative diabetic retinopathy in 25.7% and diabetic macular edema in 22.5% of patients. Conclusion. The duration of diabetes is one of the most significant factors for the development of diabetic maculopathy and the progression from nonproliferative to its proliferative stage. There is significantly higher incidence of proliferative diabetic retinopathy and diabetic macular edema in patients with increased serum level of glycosylated hemoglobin. Diabetes accompanied by hypertension is related to worsening of the clinical course of diabetic eye diseases and developing diabetic macular edema and proliferative diabetic retinopathy.

Objectives: The aim of this study was to evaluate the major determinants of diabetic retinopathy. Study Design: Cross sectional, case control study. Setting: Department of Biochemistry, Basic Medical Sciences Institute, Jinnah Post Graduate Medical Centre, Karachi. Period: March 2015 to April 2016. Material & Methods: Ethical approval was taken from the Institutional Review Board of JPMC. A total of 208 people including type 2 diabetic patients and healthy control subjects; of male gender, aged between ≥30 years and ≤ 60 years were recruited and assigned to four study groups. Each group comprise of 52 individuals, depending on the ophthalmoscopy findings, i.e. healthy controls, diabetic without retinopathy (NDR), diabetic with non-proliferative diabetic retinopathy (NPDR) and diabetic with proliferative diabetic retinopathy (PDR). Fasting blood sugar was estimated using GOD-PAP method, while HbA1c was estimated by HPLC method. Data was analyzed on SPSS software version 16. Results: Diabetics with Diabetic Retinopathy had a poor glycemic control as compare to Diabetics without Diabetic Retinopathy (FBS; 109.12 ± 13.81 vs. 184.29 ± 40.07 vs. 188.6 ± 47.68 vs. 217.06 ± 62.33; p-value = 0.001) (HbA1c; 6.73 ± 0.56 vs. 8.40 ± 1.77 vs. 9.71 ± 1.85 vs. 14.91 ± 3.87; p-value = 0.001). For Diabetic Retinopathy the odds ratio of glycemic control i.e. FBS was observed as 1.019 & HbA1c was recorded as 1.561; which was statistically significant. Conclusion: Glycemic indicators; including FBS and HbA1c, are found to be the major determinants of Diabetic Retinopathy in our study.

Abstract Objectives Periodontitis and diabetes are known to have a bidirectional relationship. Diabetic macular edema is a complication of diabetes that is strongly influenced by inflammatory pathways. However, it remains to be established whether inflammation at other locations, such as periodontitis, affects diabetic macular edema. Here, we investigated the prevalence of periodontitis in patients treated for diabetic macular edema. Materials and methods Patients with diabetic macular edema were recruited for this cross-sectional study at the Medical University of Graz. Macular edema was documented by optical coherence tomography. Periodontal status was assessed by computerized periodontal probing and panoramic X-ray imaging. Bleeding on probing, clinical attachment level, probing pocket depth, and plaque index were compared between different stages of diabetic retinopathy. Results Eighty-three eyes of 45 patients with diabetic macular edema were enrolled. Forty-four eyes (53.0%) had early stages of diabetic retinopathy (mild and moderate), and 39 eyes (47.0%) had late stages (severe and proliferative). Patients with mild or moderate DR were more likely to have more severe periodontal conditions than patients with severe or proliferative DR. Fourteen patients with mild DR (82.4%), 7 patients with moderate DR (87.5%), 4 patients with severe DR (100.0%), and 15 patients with proliferative DR (93.8%) had some degree of PD. The periodontal inflamed surface areas and the percentages of tooth sites that bled on probing were significantly higher in patients with early stages of diabetic retinopathy than in those with late stages of the disease (p < 0.05). Patients with periodontal inflamed surface areas of more than 500 mm2 required significantly more intravitreal injections in the last year than those with milder forms of periodontitis (n = 6.9 ± 3.1 versus n = 5.0 ± 3.5, p = 0.03). Conclusion In patients with diabetic macular edema, periodontitis is more prevalent in early stages of diabetic retinopathy. We suggest regular dental check-ups for diabetic patients, especially when diabetic macular edema is already present. Clinical relevance Patients with diabetic macular edema should be screened for periodontitis and vice versa, particularly early in the course of diabetes.

The most described techniques used to detect diabetic retinopathy and diabetic macular edema have to be interpreted correctly, such that a person not specialized in ophthalmology, as is usually the case of a primary care physician, may experience difficulties with their interpretation; therefore we constructed, validated and implemented as a mobile app a new tool to detect diabetic retinopathy or diabetic macular edema (DRDME) using simple objective variables. We undertook a cross-sectional, observational study of a sample of 142 eyes from Spanish diabetic patients suspected of having DRDME in 2012–2013. Our outcome was DRDME and the secondary variables were: type of diabetes, gender, age, glycated hemoglobin (HbA1c), foveal thickness and visual acuity (best corrected). The sample was divided into two parts: 80% to construct the tool and 20% to validate it. A binary logistic regression model was used to predict DRDME. The resulting model was transformed into a scoring system. The area under the ROC curve (AUC) was calculated and risk groups established. The tool was validated by calculating the AUC and comparing expected events with observed events. The construction sample (n= 106) had 35 DRDME (95% CI [24.1–42.0]), and the validation sample (n= 36) had 12 DRDME (95% CI [17.9–48.7]). Factors associated with DRDME were: HbA1c (per 1%) (OR = 1.36, 95% CI [0.93–1.98],p= 0.113), foveal thickness (per 1 µm) (OR = 1.03, 95% CI [1.01–1.04],p< 0.001) and visual acuity (per unit) (OR = 0.14, 95% CI [0.00–0.16],p< 0.001). AUC for the validation: 0.90 (95% CI [0.75–1.00],p< 0.001). No significant differences were found between the expected and the observed outcomes (p= 0.422). In conclusion, we constructed and validated a simple rapid tool to determine whether a diabetic patient suspected of having DRDME really has it. This tool has been implemented on a mobile app. Further validation studies are required in the general diabetic population.

Purpose: To explore the relationships of region-specific properties of ultra-widefield fluorescence angiography (UWFFA) images with two adverse outcomes, diabetic macular edema (DME) and proliferative diabetic retinopathy (PDR), and also the severity of diabetic retinopathy (DR).Methods: A cross-sectional observational study was performed to retrospectively analyze UWFFA images of patients with DR. All patients underwent UWFFA and optical coherence tomography examination. Leakage index and microaneurysm (MA) count were measured using Trainable Weka Segmentation, a machine learning algorithm, and ischemic index (ISI) was measured manually. The correlation between UWFFA parameters and severity of DR was analyzed, and receiver operating characteristic curves were used to estimate their diagnostic value for DME and PDR.Results: A total of 108 eyes from 108 patients with DR (mean age of 56.04 ± 8.85 years) were analyzed. As the severity of DR increased, the ISI and leakage index of the panretina and all subregions increased. Panretinal MA count and leakage index were significantly higher in eyes with DME than those without DME (p = 0.044 and 0.001, respectively). Leakage index and ISI were significantly higher in eyes with PDR than those without PDR in both panretinal and subregion-specific measurements (all p &lt; 0.05). Throughout the retina and specifically in the posterior area (PoA), the leakage index had a higher diagnostic value for DME than ISI or MA count (all p &lt; 0.05). The diagnostic value of MA count for PDR was lower than that of ISI and leakage index (all p &lt; 0.05).Conclusion: The ISI, leakage index, and MA count in the PoA and panretina correlated with the severity of DR, especially the posterior parameter. The leakage index was more valuable than ISI and MA count in determining the occurrence of DME. ISI and leakage index were better predictors of PDR.

Introduction :  Diabetic Retinopathy (DR) is one of the major cause of visual acuity deterioration in diabetic patients. The loss of central visual acuity in diabetic patients are mainly due to macula edema, which is found in 29% diabetic patients with the over 20 years duration of disease. The aim of this study is to evaluate and investigate the possible correlation among changes of visual acuity (VA), central macular thickness (CMT) using Spectral Domain Optical Coherence Tomography (SD-OCT). Electrophysiological responses using multifocal electroretinography (MfERG) in diabetic macular edema (DME) following intravitreal injection of bevacizumab. Methods: Single arm clinical trial. Thirty-three eyes of 33 DME patients (16 non-proliferative diabetic retinopathy and 17 non-high-risk proliferative diabetic retinopathy), receives intravitreal bevacizumab 1,25mg. All patients underwent complete ophthalmic examination including ETDRS VA testing, Sixty-one scaled hexagon MfERG and SD-OCT scan at baseline, 1-week and 1-month post-injection. Components of the first order kernel (N1, N2 and P1) in central 2o were measured. Result : MfERG showed reduced P1 amplitude (P<0.05) at 1-week after injection followed by increased P1 amplitude (P>0.05) at 1-month after treatment as compared to the baseline in all subjects. There was 19% improvement CMT and 0.2Logmar VA improvement in 1-month post-injection compared to the baseline (P<005). This study showed no serious ocular adverse effects. There was no significant correlation between changes in visual acuity with changes in CMT or other MfERG parameters. Conclusion: Intravitreal injection bevacizumab resulting in improved VA, reduction in CMT and mild improvement in the MfERG responses. Although VA changes did not correlate with reduced CMT nor with improved responses of MfERG, the combined use of SD-OCT and MfERG may be used to evaluate macular function in DME patient with worsened visual acuity post anti-VEGF injection.

Objectives: Blindness is one of the most widespread final pathways of diabetic retinopathy and its associated diabetic macular edema. The general practitioners are the first to encounter these diabetic patients. Fundoscopy is now considered as an ideal way for the diagnosis of patients with diabetic retinopathy. Therefore, this study was undertaken to know the ability and skills of general practitioners for the diagnosis and management of patients with diabetic retinopathy and diabetic macular edema. Methods: This study was conducted in all major cities in Qassim province of Saudi Arabia during January to May 2017. A validated questionnaire was used to assess the general practitioners’ knowledge and practice for the management of diabetic retinopathy and diabetic macular edema. Questions related to referrals, diagnosis, and treatment options to diabetic retinopathy and diabetic macular edema were asked to the general practitioners. Results: Of 96 general practitioners, 76 returned the questionnaire with a response rate of 79.2%. Only 26.3% general practitioners referred patients with type 1 diabetes to ophthalmologists as per guidelines set by the American Academy of Ophthalmology, whereas 74% of general practitioners showed good knowledge for referring patients with type 2 diabetes to ophthalmology clinics. Lack of knowledge was also noticed for the treatment of diabetic retinopathy, as only 36.8% of general practitioners replied positive for dilated fundus examination option, whereas 78.9% of general practitioners chose laser photocoagulation as a treatment option. Similar response from them was observed for patients with diabetic macular edema. Furthermore, data also showed years in practice of general practitioners was well correlated with their knowledge for the management of diabetic retinopathy and diabetic macular edema. Conclusion: The general practitioners included in this study showed lack of knowledge in handling patients with diabetic retinopathy and diabetic macular edema. Therefore, refresher courses are needed that highlight the acquisition of their skills in fundoscopy.

Diabetic macular edema and proliferative diabetic retinopathy is the most important cause of vision loss in diabetic patients. Vascular endothelial growth factor has been shown to play a major role in retinal neovascularization and vascular hyperpermeability in eyes with diabetic patients. Recent studies have demonstrated the usefulness of an intravitreal injection of bevacizumab in the reduction of diabetic macular edema, vascular permeability, and fibrovascular proliferation in retinal neovascularization secondary to proliferative diabetic retinopathy. This review aimed to evaluate the intravitreal bevacizumab in diabetic retinopathy and diabetic macular edema.
