Opaque/hazy ocular media preventing fundus visualization, Coexisting ocular disorders likely to mask the findings of diabetic retinopathy, Patients with presence of any of the confounding factors, like fever, active systemic infections, exercise, high protein intake, accelerated hypertension, congestive heart failure, patients not willing to participate in the study were excluded from the study. RESULTS: 444 subjects of either gender were included in our study, out of which 236 patients were females and the rest were males. Majority of the patients lied in the age group of 41-60 years (54.73%) followed by 61-80 years (29.28%) and 20-40 years (15.09%), while only 4(0.90%) patients were aged > 80 years. A statistically significant association with severity of retinopathy and the age of the patients was observed. Proportion of Group I (No retinopathy) was higher in younger patients i.e. 20-40 (74.6%) and 41-60 (54.3%) as compared to elderly cases i.e. 61-80 (46.2%) and this difference was found to be statistically significant (p < 0.001). Statistically significant association was found between the severity of retinopathy and duration of diabetes (p < 0.001). Proportion of severe to very severe retinopathy and proliferative diabetic retinopathy were higher in higher grade of microalbuminuria (Grade II and Grade III). A statistically significant association between microalbuminuria grade and severity of retinopathy was observed (p < 0.001). Total cholesterol was found to be high (240 mg/dl) in 13.74%patients. Prevalence of retinopathy was 60.7%, in patients having high total cholesterol levels. Proportional difference in severity of retinopathy in patients with different total cholesterol levels was found to be statistically significant (p = 0.002). Trivariate analysis between severity of retinopathy, microalbuminuria and serum cholesterol levels, revealed that in microalbuminuria grade 0, difference in prevalence of retinopathy in patients with different serum cholesterol levels was not found to be statistically significant. CONCLUSION: Duration of diabetes and microalbuminuria have been found to be the independent risk factors for diabetic retinopathy, but serum cholesterol levels did not show an independent role in our study. The findings in present study endorsed the view that microalbuminuria poses a risk for diabetic retinopathy which is affected by duration of diabetes, level of glycemic control and lipid levels.

International Journal of Ophthalmic Research
Department of Medicine of our facility. All cases were subjected to complete ocular examination after taking demographic and medical history. Diabetic Retinopathy was graded as per ETDRS categories. Biochemical investigations like serum creatinine, serum urea, urine microalbumin levels, Blood sugar (fasting/post prandial), HbA1c were done. RESULTS: Out of 444 cases, Male to female ratio was 0.88: 1, where majority (54.73%) were aged between 41-60 years. 246 patients who did not suffer from retinopathy were grouped as Group I, while the rest of 198 patients having retinopathy were categorized as Group II. This was further divided into IIA suffering from Very mild to moderate NPDR (58.59%), IIB suffering from Severe to very severe NPDR (29.29%), and those suffering from Proliferative diabetic retinopathy were grouped as IIC (12.12%).A statistical significant association with severity of diabetic retinopathy and duaration of diabetes was observed. A statistically significant association between severity of diabetic retinopathy and HbA1c values was found (p < 0.001). A statistically significant association between grade of microalbuminuria and severity of diabetic retinopathy was observed (p < 0.001). On trivariate analysis of severity of diabetic retinopathy, HbA1C level and microalbuminuria grade, a statistically significant difference in prevalence of diabetic retinopathy in different HbA1c levels with microalbuminuria Grade 0 was found (p < 0.001). The difference in proportion of patients suffering from very mild to moderate diabrtic retinopathy with duration of diabetes was found to be statistically significant (p < 0.001) in grade I microalbuminuria. Difference in proportion of patients suffering from diabetic retinopathy with duration of diabetes was found to be statistically significant in grade II microalbuminuria (p < 0.001). In grade III microalbuminuria, this difference was not found to be statistically significant (p = 0.093). CONCLUSION: Microalbuminuria poses a risk for diabetic retinopathy which is affected by duration of diabetes and level of glycemic control. Microalbuminuria of higher grades is a strong predictor for occurrence and severity of diabetic retinopathy.

Diabetic retinopathy is one of the leading causes of blindness in working-age individuals. Diabetic patients with proteinuria or those on dialysis usually present severe forms of diabetic retinopathy, but the association of diabetic retinopathy with early stages of diabetic nephropathy has not been entirely established. A cross-sectional study was conducted on 1214 type 2 diabetic patients to determine whether microalbuminuria is associated with proliferative diabetic retinopathy in these patients. Patients were evaluated by direct and indirect ophthalmoscopy and grouped according to the presence or absence of proliferative diabetic retinopathy. The agreement of diabetic retinopathy classification performed by ophthalmoscopy and by stereoscopic color fundus photographs was 95.1% (kappa = 0.735; P &amp;lt; 0.001). Demographic information, smoking history, anthropometric and blood pressure measurements, glycemic and lipid profile, and urinary albumin were evaluated. On multiple regression analysis, diabetic nephropathy (OR = 5.18, 95% CI = 2.91-9.22, P &amp;lt; 0.001), insulin use (OR = 2.52, 95% CI = 1.47-4.31, P = 0.001) and diabetes duration (OR = 1.04, 95% CI = 1.01-1.07, P = 0.011) were positively associated with proliferative diabetic retinopathy, and body mass index (OR = 0.90, 95% CI = 0.86-0.96, P &amp;lt; 0.001) was negatively associated with it. When patients with macroalbuminuria and on dialysis were excluded, microalbuminuria (OR = 3.3, 95% CI = 1.56-6.98, P = 0.002) remained associated with proliferative diabetic retinopathy. Therefore, type 2 diabetic patients with proliferative diabetic retinopathy more often presented renal involvement, including urinary albumin excretion within the microalbuminuria range. Therefore, all patients with proliferative diabetic retinopathy should undergo an evaluation of renal function including urinary albumin measurements.
Study of Prevalence of Diabetic Retinopathy in Diabetics with Microalbuminuria
2019
Background: The concordance of microalbuminuria and diabetic retinopathy (DR) has been well reported in persons with type 1 diabetes; however, for type 2 diabetes, there is paucity of data especially from population based studies. The aim of this study was to estimate the prevalence of microalbuminuria among persons with type 2 diabetes. Methods: A population-based cross sectional study was conducted in cohort of 160 subjects with type 2 diabetes. All the subjects underwent comprehensive eye examination with the help of indirect ophthalmoscope by the practicing ophthalmologist. A morning urine sample was tested for albuminuria. Subjects were considered to have microalbuminuria, if the urinary albumin excretion was between 30 and 300 mg/24 hours. The statistical software used was SPSS for Windows and X test, to compare proportions amongst groups were used. Results: The prevalence of microalbuminuria in the study subjects was 27.5% (44/160). Overall prevalence of Diabetic Retinopathy ...

To evaluate the association of microalbuminuria with the severity of diabetic retinopathy. Methodology: This is a cross-sectional study that was conducted at Combined Military Hospital Lahore from Dec 2019 to Dec 2020. All Patients having type II diabetes mellitus fulfilling the inclusion and exclusion criteria were selected for this study. All patients underwent complete ocular examination including fundoscopy to grade the stage of diabetic retinopathy using the ETDRS chart. To assess the extent of microalbuminuria, a urine albumin to creatinine ratio was carried out using the urine spot test and classified as mild, moderate and severe according to KIDGO 2012 clinical practice guidelines. Results: Out of 300 patients 104 (34.6%) had some stage of diabetic retinopathy. Microalbuminuria was present in all (104) patients with diabetic retinopathy and in 55 (28.06%) patients with no diabetic retinopathy. The severity of microalbuminuria correlates with the advancement in stages of retinopathy with a p value < 0.001 as the number of patients with moderate and severe microalbuminuria had higher stages of diabetic retinopathy. None of the patients with very mild diabetic retinopathy had moderately or severely increased microalbuminuria whereas 88% of patients with advanced diabetic retinopathy had moderately increased microalbuminuria and 4% had severely increased microalbuminuria. Furthermore, 76% of the patients had moderately increased and 12% had severely increased microalbuminuria in patients >7 HbA1c and only 28% of patients had moderately increased microalbuminuria and none had severely increased microalbuminuria in patients with ≤ 7 HbA1c. Conclusion: This study showed that the degree of microalbuminuria increases with each higher stage of diabetic retinopathy.

This cross-sectional study looked at the prevalence of microalbuminuria and retinopathy in a cohort of 926 young, Type 1 and Type 2 diabetes mellitus (DM) patients, and determined the factors which were associated with these microvascular complications. The prevalence of microalbuminuria, defined as the albumin:creatinine ratio ] 2.5 (for males) or ]3.5 mg/mmol (for females), was 13.4% in Type 1 DM, 69.5% in insulin-requiring Type 2 DM and 16% in Type 2 DM treated only with oral hypoglycemic agents. Compared to those with normal renal functions, these patients were older (P5 0.01), had significantly elevated blood pressures (P B 0.01 or P= 0.0001), and in the case of Type 1 DM, with a higher body mass index (P= 0.0001) and waist -hip ratio (P B 0.01). The prevalence of diabetic retinopathy in Type 1 DM was found to increase with the duration of diabetes, from 1.4% in the newly-onset (B 5 years), to 9.9% in those with 5-10 years disease, to 35% among patients with more than 10 years of diabetes (PB0.0001). In this study, it was also observed that 10% of the Type 2 DM patients already had retinopathy within 5 years of diagnosis, and the prevalence increased significantly to 42.9% (PB 0.0001) among patients who had been diabetics for more than 10 years. Stepwise multiple regression analysis showed that besides the disease duration, systolic blood pressure was the most common and significant determinant for both microalbuminuria and retinopathy in both types of DM, thus implying that in order to reduce the risk of microvascular complications in diabetes mellitus, systolic and not just the diastolic blood pressure, should be effectively controlled.
