Eye disorders other than diabetic retinopathy in patients with diabetes

Purpose. To identify any possible relation between glycaemic control and previous laser photocoagulation for diabetic retinopathy.Methods. Seventy-two patients with diabetes were included in the study and were separated into 2 groups according to previous treatment (group A) or not (group B) with argon laser photocoagulation. Glycaemic control was estimated by measuring blood levels of HbA1c in four consecutive measurements.Results. Blood levels of HbA1c in group A were significantly lower 3, 6, and 12 months after laser treatment as compared to blood levels of HbA1c before laser treatment (7.1±0.4% versus7.6±0.9%,7.2±0.2% versus7.6±0.9%, and7.1±0.2% versus7.6±0.9%, resp., allP<0.05). Blood levels of HbA1c in group B did not differ significantly in four consecutive measurements.Conclusion. Our results suggest that we should anticipate a better glycaemic control in cases of patients with diabetes previously treated with laser photocoagulation.

Knowledge Attitude And Practice

Background: Diabetes mellitus is a common metabolic disorder which is characterized by elevated blood sugar level. It is a major cause of blindness in our country, which is preventable and treatable, if healthy practice and knowledge regarding this disease is applied. The study was undertaken to assess the knowledge, attitude and practice of Diabetic Retinopathy, amongst diabetic patients attending eye OPD in GMC Jammu.Methods: 300 patients diagnosed with diabetes mellitus attending eye OPD, over a period of 10 months, in GMC Jammu, were incorporated in this study. Self administered questionnaires were used to assess knowledge, practice and attitude of diabetic retinopathy amongst the diabetic patient, after their due consent.Results: This study incorporated 300 diabetic patients out of which 168 (56%) were males and 132 (44%) were females. Most of the patients (70%) were aware of the fact that diabetes can cause eye disorders. 67.33% believed that they should go for regular eye check-ups. 79.33% agreed that timely intervention can delay the complications in diabetic eye disease.Conclusions: Diabetes can lead to serious ocular complications which can be prevented by appropriate awareness and optimistic attitude and good approach towards the disease.

AbstractThe aim of this study was to measure macular perfusion in patients with type 1 diabetes and no signs of diabetic retinopathy (DR) using volume rendered three-dimensional (3D) optical coherence tomography angiography (OCTA). We collected data from 35 patients with diabetes and no DR who had OCTA obtained. An additional control group of 35 eyes from 35 healthy subjects was included for comparison. OCTA volume data were processed with a previously presented algorithm in order to obtain the 3D vascular volume and 3D perfusion density. In order to weigh the contribution of different plexuses’ impairment to volume rendered vascular perfusion, OCTA en face images were binarized in order to obtain two-dimensional (2D) perfusion density metrics. Mean ± SD age was 27.2 ± 10.2 years [range 19–64 years] in the diabetic group and 31.0 ± 11.4 years [range 19–61 years] in the control group (p = 0.145). The 3D vascular volume was 0.27 ± 0.05 mm3 in the diabetic group and 0.29 ± 0.04 mm3 in the control group (p = 0.020). The 3D perfusion density was 9.3 ± 1.6% and 10.3 ± 1.6% in diabetic patients and controls, respectively (p = 0.005). Using a 2D visualization, the perfusion density was lower in diabetic patients, but only at the deep vascular complex (DVC) level (38.9 ± 3.7% in diabetes and 41.0 ± 3.1% in controls, p = 0.001), while no differences were detected at the superficial capillary plexus (SCP) level (34.4 ± 3.1% and 34.3 ± 3.8% in the diabetic and healthy subjects, respectively, p = 0.899). In conclusion, eyes without signs of DR of patients with diabetes have a reduced volume rendered macular perfusion compared to control healthy eyes.

Endothelial Growth Factor

Eye disorders have a special place in diabetes since visual impairment has a significant effect on the quality of life. Therefore, determining risk factors and prognostic criteria for disease course are essential for developing strategies for early prevention of diabetic retinopathy (DR). This paper addresses studies on various aspects of DR in patients with myopia. It was demonstrated that DR arises, develops, and progresses in different ways under various axial lengths (AL). Thus, many authors report that DR barely occurs in high myopia. Some of them account for this phenomenon for poor blood circulation in a long myopic eye. Others refer to a significantly lower vascular endothelial growth factor (VEGF) concentration in longer eyes or eyes with myopic refraction. The third authors argue a focal disintegration of retinal pigment epithelium to eliminate metabolic end products through the choroid and sclera. As a result, neither acidosis nor venous congestion develops, and endothelial barrier function remains unaffected Keywords: diabetic retinopathy, myopia, axial length, vascular endothelial growth factor, emmetropia, hyperopia, diabetes.
