Background. Diabetic retinopathy, one of the major complications of diabetes, is one of the leading causes of low vision and blindness. One of the main causes of decreased central vision in patients with diabetic retinopathy and type 2 diabetes mellitus is diabetic maculopathy (DMP). DMP with possible development of diabetic maculopathy edema can be detected even in patients with initial changes in the fundus. The purpose was to investigate the safety profile and effectiveness of various modern vitreoretinal interventions in the treatment of diabetic maculopathy. Materials and methods. We observed 313 patients with type 2 diabetes mellitus (313 eyes) with DMP and initial (group I; n = 40), moderate-to-severe non-proliferative (group II; n = 92) and proliferative diabetic retinopathy (group III; n = 181). All patients underwent conventional ophthalmological examinations. Three hundred and thirteen patients (313 eyes) who underwent surgical treatment were divided into 4 observation groups: group 1 — 78 people (78 eyes) who underwent pars plana vitrectomy 25G (PPV); group 2 — 85 individuals (85 eyes) who underwent PPV and internal limiting membrane (ILM) peeling; group 3 — 81 patients (81 eyes) who underwent PPV, ILM peeling and panretinal photocoagulation (PPC); group 4 — 69 people (69 eyes) who underwent PPV, ILM peeling, PPC and phacoemulsification. The nature and frequency of surgical, postoperative complications and the effectiveness of different vitreoretinal interventions were studied. Terms of observation were 1, 3, 6 months and 1 year after surgery. Results. The effectiveness of different vitreoretinal interventions was studied 1, 3 and 6 months after surgery. High efficiency of intervention for all types of vitrectomy is established. Modern vitreoretinal interventions in the treatment of DMP and diabetic maculopathy edema is effective after 1 month in 60.7, 82.4, 85.2 and 68.12 % of cases, and after one year — in 76.0, 75.0, 73.1 and 73.5 %, respectively. The recurrence rate of DMP one year after vitreoretinal interventions was 24.0–27.0 % and did not depend on their modification. The effectiveness of DMP treatment depended on the stage of diabetic retinopathy and was 72.5 % in the initial non-proliferative diabetic retinopathy, 77.2 % with moderate-to-severe non-proliferative diabetic retinopathy and 66.3 % with proliferative diabetic retino-pathy. Recurrences of DMP were divided into three types: early transient, early persistent and late. The most frequent were early persistent relapses, which ranged from 16.1 to 25.6 % taking into account different methods of treatment. Conclusions. All stages of surgery must be strictly justified. The risks of each stage of the intervention should always be considered to obtain optimal functional results, especially in the long-term follow-up.

Background and Objectives: The global epidemic of diabetes, especially type 2 (DM2), is related to lifestyle changes, obesity, and the process of population aging. Diabetic retinopathy (DR) is the most serious complication of the eye caused by diabetes. The aim of this research was to assess the prevalence of diabetic retinopathy in type 1 and type 2 diabetes mellitus patients in north-east Poland. Materials and Methods: The eye fundus was assessed on the basis of two-field 50 degrees color fundus photographs that showed the optic nerve and macula in the center after the pupil was dilated with 1% tropicamide. Results: The experimental group included 315 (26%) patients with type 1 diabetes mellitus (DM1) and 894 (74%) patients with DM2. DM1 patients were diagnosed with DR in 32.58% of cases, with non-proliferative diabetic retinopathy (NPDR) in 24.44% of cases, proliferative diabetic retinopathy (PDR) in 1.59% of cases, diabetic macular edema (DME) in 5.40% of cases, and PDR with DME in 0.95% of cases. DR was found in DM2 patients in 23.04% of cases, NPDR in 17.11% of cases, PDR in 1.01% of cases, DME in 4.81% of cases, and PDR with DME in 0.11% of cases. Conclusions: The presented study is the first Polish study on the prevalence of diabetic retinopathy presenting a large group of patients, and its results could be extrapolated to the whole country. Diabetic retinopathy was found in 25.48% of patients in the whole experimental group. The above results place Poland within the European average, indicating the quality of diabetic care offered in Poland, based on the number of observed complications.

Objective Adropin, a newly identified regulatory protein encoded by Enho gene, is correlated with insulin sensitivity and diabetes. The aim of this study is to determine whether serum and vitreous adropin concentrations are correlated with the presence of diabetic retinopathy. Methods A population of 165 patients with type 2 diabetes mellitus (52 without diabetic retinopathy, 69 with non-proliferative diabetic retinopathy and 44 patients with proliferative diabetic retinopathy) was enrolled in this study. The control group enrolled 68 healthy subjects who had underwent vitrectomy for retinal detachment. Serum and vitreous adropin concentrations were examined using enzyme-linked immunosorbent assay method. Results Control subjects had significantly higher serum and vitreous adropin concentrations compared with diabetic patients. Serum and vitreous adropin concentrations in proliferative diabetic retinopathy patients were significantly reduced compared with those in non-proliferative diabetic retinopathy patients and type 2 diabetes mellitus patients without diabetic retinopathy. In addition, there were lower serum and vitreous adropin concentrations in non-proliferative diabetic retinopathy patients compared with type 2 diabetes mellitus patients without diabetic retinopathy. Logistic regression analysis revealed that serum and vitreous adropin were associated with a decreased risk of type 2 diabetes mellitus and diabetic retinopathy. Conclusion Serum and vitreous adropin concentrations are negatively associated with the presence of diabetic retinopathy.

  Objectives: In India, 69.1 million are diabetics as of 2015 compared to 18 million in 1995. Pan India prevalence study in diabetics carried out at 194 centers by All India Ophthalmological Society reported the prevalence of diabetic retinopathy (DR) among diabetics as 21.8%. DR is of two types, non-proliferative diabetic retinopathy (NPDR), and proliferative diabetic retinopathy (PDR). The severity of NPDR depends on microaneurysms, hemorrhages, cotton wool spots, and beading of veins and can progress to PDR. Inherit characteristic of PDR is neovascularization. The aim of this observational prevalence study is to study the prevalence of diabetic retinopathy in Type 2 diabetic patients attending diabetic clinic and to study the distribution of diabetic retinopathy with respect to age, sex, and duration of disease in a tertiary care hospital in southern India.Methods: This is a retrospective observational study. Age above 20 years and patients diagnosed with Type 2 diabetes mellitus (DM) and examined by the ophthalmologist were included and others excluded. Data documented were analyzed using statistical software SPSS version 16.Results: About 52.07% of patients with Type 2 DM for more than 10 years had diabetic retinopathy and 13.07 % of patients with Type 2 DM for more than 5 years have diabetic retinopathy.Conclusion: India being the diabetic capital of the world and DR being the most common cause for visual impairment and blindness and it becomes empirical to assess the factors for its rising prevalence, which will significantly contribute in reducing the progression of DR.

Aim/hypothesis The aim of our study was to characterize the human salivary proteome and determine the changes in protein expression in 2 different stages of diabetic retinopathy with type-2 diabetes mellitus: (1) with non-proliferative diabetic retinopathy (NPDR) and (2) with proliferative diabetic retinopathy (PDR). Type-2 diabetes without diabetic retinopathy (XDR) was designated as control. Method In this study, 45 saliva samples were collected (15 samples from XDR control group, 15 samples from NPDR disease group and 15 samples from PDR disease group). Salivary proteins were extracted, reduced, alkylated, trypsin digested and labeled with iTRAQ before analyzing by Orbitrap fusion tribrid mass spectrometer. Proteins annotation, fold change calculation and statistical analysis were interrogated by Proteome Discoverer. Biological pathway analysis was performed by Ingenuity Pathway Analysis. Data are available via ProteomeXchange with identifiers PXD003723-PX003725. Results A total of 315 proteins were identified from the salivary proteome and 119 proteins were found to be differentially expressed. The differentially expressed proteins from the NPDR disease group and the PDR disease group were assigned to respective canonical pathways indicating increased LXR/RXR activation, FXR/RXR activation, acute phase response signaling, sucrose degradation V and regulation of actin-based motility by Rho in the PDR disease group compared to the NPDR disease group Conclusions/Interpretation Progression from non-proliferative to proliferative retinopathy in type-2 diabetic patients is a complex multi-mechanism and systemic process. Furthermore, saliva was shown to be a feasible alternative sample source for diabetic retinopathy biomarkers.
