Abstract

Objective: To identify an optical coherence tomography (OCT) pattern predictive of visual outcome in patients with diabetic macular edema (DME) who underwent a single dose of intravitreal triamcinolone., Design: Retrospective case analysis with prospective data collection for controls., Participants: Ninety-three cases and 25 controls., Methods: Two independent masked observers retrospectively examined preoperative macular OCTs of 93 eyes of 93 patients who were given a single dose (4 mg in 0.1 ml) of intravitreal triamcinolone for DME and categorized them as belonging to 2 groups: 1, comprised of eyes with high reflectivity (bright colors) from inner retinal layers, and 2, comprised of eyes that had low reflectivity (darker colors) from inner retinal layers. Logarithm of the minimum angle of resolution visual acuity (VA) and macular thickness measured by OCT were assessed preoperatively and postoperatively at 1 and 3 months., Main Outcome Measures: Optical coherence tomographic appearance of inner retinal layers., Results: All patients completed 3 months of follow-up. In group 1, 45 of 51 eyes (88%) experienced visual improvement of > or =2 lines on an Early Treatment Diabetic Retinopathy Study (ETDRS) chart at 1 month of follow-up. Forty-four of 51 patients (86%) experienced visual improvement of > or =2 lines on an ETDRS chart at 3 months of follow-up. In group 2, 18 of 42 patients (43%) experienced visual improvement of > or =1 lines on an ETDRS chart at 1 and 3 months of follow-up. For the remaining patients, VA remained unchanged during the postoperative course of 3 months., Conclusions: Patients in whom OCT demonstrated the high reflectivity of inner retinal layers achieved greater VA though macular thickness decreased significantly after intravitreal triamcinolone in both groups. It may be hypothesized that a lower optical reflectivity of inner retinal layers is related to the atrophy of the inner retinal layers, thus resulting in a failure of VA recovery in these patients. The level of reflectivity from inner retinal layers on OCT may provide objective criteria in predicting the response of DME to intravitreal triamcinolone and help in preoperative counseling of patients with DME.

Abstract

Aim: To evaluate the efficacy of intravitreal triamcinolone (IVTA) for the treatment of diffuse diabetic macular oedema (DME) refractory to conventional argon macular laser therapy., Methods: A prospective, consecutive, and noncomparative case series was undertaken involving 38 eyes of 38 patients with refractory DME. Triamcinolone acetonide (4 mg) in 0.1 ml was injected intravitreally. LogMar visual acuity (VA) and macular thickness measured by ocular coherence tomography (OCT) were assessed preoperatively and postoperatively at 1, 3, and 6 months., Results: All patients completed 6 months of follow up. VA (mean+/-SD) improved from 0.905+/-0.23 to 0.605+/-0.28, 0.555+/-0.29, and 0.730+/-0.30 at 1, 3, and 6 months, respectively. Macular thickness baseline (mean+/-SD) on OCT was 418.7+/-104.2 microm and this decreased to 276.9+/-72.6 microm, 250.6+/-53.1 microm, and 308.8+/-87.3 microm at 1, 3, and 6 months, respectively., Conclusions: IVTA may be a potential temporary treatment for refractory DME. It is effective in decreasing macular thickness and improving VA but the effect lasts approximately for 6 months in the majority of patients. Further investigations are required to establish the safety of IVTA for the treatment of DME.

Abstract

Several studies have shown an association between blood pressure and nephropathy, but few have been large enough to examine whether, or how, this relation is influenced by retinopathy. We have therefore examined the independent relations of blood pressure to urinary albumin excretion and retinopathy in a cross-sectional observational study of over 3000 insulin-dependent diabetic patients (the EURODIAB IDDM Complications Study). The relation of blood pressure to urinary albumin excretion differed strikingly between patients with (46%) and without (54%) retinopathy. In those with retinopathy, mean urinary albumin excretion rate was normal (20 micrograms/min) below median diastolic pressure (75 mmHg) and increased steeply (p0.001) with blood pressure above this level. However, in patients without retinopathy, mean albumin excretion rate was normal across the range of diastolic pressure. This finding could not be explained by differences in glycaemic control or duration of diabetes between patients with and without retinopathy. These data identify a subgroup of patients whose high risk of nephropathy may reflect abnormal renal vulnerability to mildly raised blood pressure. Retinopathy is a close correlate of this vulnerability. Detection of even mild retinopathy, together with raised blood pressure, may be important in assessing nephropathy risk.

Abstract

OBJECTIVE To examine the relationship between smoking and both glycemic control and microvascular complications in patients with insulin-dependent diabetes mellitus (IDDM). RESEARCH DESIGN AND METHODS This was a prevalence survey of 3,250 men and women aged 15–60 years with IDDM from 31 diabetes centers in 16 European countries. Participants completed a questionnaire, had retinal photographs taken, and performed a 24-h urine collection. HbA1c, frequency of hypoglycemic and ketoacidotic episodes, urinary albumin excretion rates, and retinopathy were compared by smoking category. RESULTS The prevalence of smoking was 35% in men and 29% in women. Current smokers had poorer glycemic control and, among men, were more likely to have had a ketoacidotic episode than were those who never smoked. Ex-smokers had equivalent glycemic control and marginally more hypoglycemic episodes did than those who never smoked. Current smokers had a higher prevalence of microalbuminuria and total retinopathy than did those who never smoked. Ex-smokers had a higher prevalence of macroalbuminuria and proliferative retinopathy than did those who never smoked, but both had a similar prevalence of microalbuminuria. Adjustment for either current or long-term glycemic control could not fully account for these differences. CONCLUSIONS Smoking is associated with poorer glycemic control and an increased prevalence of microvascular complications compared with not smoking. Ex-smokers can achieve glycemic control equivalent to and have a prevalence of early complications similar to that of those who never smoked. We suggest that poorer glycemic control can account for some of the increased risk of complications in smokers, and that quitting smoking would be effective in reducing the incidence of complications. Urgent action is required to reduce the high smoking rates in people with IDDM.
