          Abstract

          Objetivo: Comparar los resultados obtenidos en una muestra de población de 741 pacientes diabéticos tipo II en el año 1993 con una muestra actual de 741 pacientes diabéticos tipo II, determinando la prevalencia de retinopatía diabética, y valorando el impacto sobre la misma de los nuevos criterios diagnósticos y el mayor control de los pacientes diabéticos. Métodos: Estudio transversal en el que la muestra fue recogida mediante selección al azar de 741 pacientes afectos de diabetes mellitus tipo II del total del archivo de pacientes visitados regularmente a lo largo del período comprendido entre el 1 de enero y el 31 de diciembre del año 2005. Resultados: Se observa un descenso de prevalencia de retinopatía diabética del 39,41% en el primer estudio al 27,55% actual, manteniéndose igual el edema macular (7,15% en el primer estudio y 7,90% en el actual). Se ha observado un descenso en el número de pacientes ciegos, de un 11,20% a un 4,90%. Asimismo los pacientes tratados previamente con fotocoagulación láser aumentaron en el estudio actual, un 13,49% frente a un 6,20%. En el estudio estadístico los factores de riesgo son: el tiempo de evolución de la diabetes, el tratamiento con insulina de la misma, y los niveles elevados de HbA1c. Conclusiones: El mayor control ejercido sobre los pacientes diabéticos nos permite observar una mejoría en la agudeza visual. Observándose también que aumenta el número de pacientes tratados. Por otro lado al existir un mayor número de pacientes diabéticos conocidos, se produce un efecto de disminución de la prevalencia de la retinopatía.

          Objective: The aim of the study was to compare the results with those of a previous study by the same author in 1993 when 741 type II diabetic patients were recruited. We determined the prevalence of diabetic retinopathy and the impact of the new diagnostic criteria and stricter control of diabetes on the results obtained. Methods: The study sample was obtained by hazard selection of 741 type II diabetic patients, from the total diabetic patients visited in the interval between January 1 and December 1 in 2005. Results: We observed a decrease in the prevalence of diabetic retinopathy between the two studies. In the first study the incidence was 39.41% while in the present study it was 27.55%. The diabetic macular edema prevalence was similar in both studies (7.15% in the past and 7.90% in the present study). There was also a decrease in the number of blind patients (11.20% in 1993 and 4.90% in the current study). The number of patients treated with laser photocoagulation increased (13.49% in the current study as compared to 6.20% in the previous study). Statistic analysis revealed the risk factors for retinopathy: diabetes mellitus duration, elevated HbA1C levels and the need for insulin treatment. Conclusions: A better control of diabetes mellitus may lead us to observe an increase in visual acuity, and a better control of diabetic retinopathy. The incidence of diabetic retinopathy certainly decreased between the study periods; however the overall incidence of diabetes in the community has increased during the last few years, making firm conclusions difficult.

          Epidemiology of diabetic retinopathy and macular oedema: a systematic review.

          To systematically review the literature on the prevalence and incidence of diabetic retinopathy (DR) and macular oedema (MO). A search of the bibliographic databases (Medline, Embase, CINAHL) was conducted up to October 2001. Selected relevant studies were scrutinized and included in the review. A total of 359 studies were included. The studies were reported in nearly 100 different journals and in over 50 countries. The majority of the studies were US-based, with large studies such as the Wisconsin Epidemiologic Study of Diabetic Retinopathy dominating the literature. The studies were quite dated and highly heterogeneous in nature in terms of patient selection with variable inclusion criteria (age range, gender, diabetes duration and type, ethnicity, comorbidity, and DR status, assessment, and classification). There are inconsistencies between epidemiological studies, and differences in study methods may contribute to conflicting reports of prevalence and incidence of DR and MO in diabetic populations. As new therapies for DR and its associated complications emerge, the need to capture and monitor new epidemiological data becomes increasingly important to be able to assess the impact and effectiveness of these therapies. Robust, longitudinal capture of patient data is, therefore, essential to evaluate the impact of current practice on the epidemiology of diabetic eye complications.

            Early worsening of diabetic retinopathy in the Diabetes Control and Complications Trial.

            (1998)
            To document the frequency, importance of, and risk factors for "early worsening" of diabetic retinopathy in the Diabetes Control and Complications Trial (DCCT). The DCCT was a multicenter, randomized clinical trial comparing intensive vs conventional treatment in insulin-dependent diabetic patients who had no to moderate nonproliferative retinopathy. Retinopathy severity was assessed in 7-field stereoscopic fundus photographs taken at baseline and every 6 months. For this study, worsening was defined as progression of 3 steps or more on the Early Treatment Diabetic Retinopathy Study final scale, as the development of soft exudates and/or intraretinal microvascular abnormalities, as the development of clinically important retinopathy, or as any of the above, and was considered "early" if it occurred between baseline and 12-month follow-up visits. Early worsening was observed at the 6- and/or 12-month visit in 13.1% of 711 patients assigned to intensive treatment and in 7.6% of 728 patients assigned to conventional treatment (odds ratio, 2.06; P < .001); recovery had occurred at the 18-month visit in 51% and 55% of these groups, respectively (P = .39). The risk of 3-step or greater progression from the retinopathy level present 18 months after entry into the trial was greater in patients who previously had had early worsening than in those who had not. However, the large long-term risk reduction with intensive treatment was such that outcomes in intensively treated patients who had early worsening were similar to or more favorable than outcomes in conventionally treated patients who had not. The most important risk factors for early worsening were higher hemoglobin A1c level at screening and reduction of this level during the first 6 months after randomization. We found no evidence to suggest that more gradual reduction of glycemia might be associated with less risk of early worsening. Early worsening led to high-risk proliferative retinopathy in 2 patients and to clinically significant macular edema in 3; all responded well to treatment. In the DCCT, the long-term benefits of intensive insulin treatment greatly outweighed the risks of early worsening. Although no case of early worsening was associated with serious visual loss, our results are consistent with previous reports of sight-threatening worsening when intensive treatment is initiated in patients with long-standing poor glycemic control, particularly if retinopathy is at or past the moderate nonproliferative stage. Ophthalmologic monitoring before initiation of intensive treatment and at 3-month intervals for 6 to 12 months thereafter seems appropriate for such patients. In patients whose retinopathy is already approaching the high-risk stage, it may be prudent to delay the initiation of intensive treatment until photocoagulation can be completed, particularly if hemoglobin A1c is high.

              United Kingdom Prospective Diabetes Study, 30: diabetic retinopathy at diagnosis of non-insulin-dependent diabetes mellitus and associated risk factors.

              To report on the prevalence of retinopathy in patients with newly diagnosed non-insulin-dependent diabetes mellitus (NIDDM) and to evaluate the relationship of retinopathy to clinical and biochemical variables. A multicenter, randomized, controlled clinical study of therapy in patients with NIDDM. Patients were part of the United Kingdom Prospective Diabetes Study, a 23-center study of 2964 white patients who had both eyes photographed and assessed. The presence and severity of diabetic retinopathy were evaluated by sex, and the relationship of retinopathy to medical and biochemical parameters was assessed. Retinopathy, defined as microaneurysms or worse lesions in at least 1 eye, was present in 39% of men and 35% of women. Marked retinopathy with cotton wool spots or intraretinal microvascular abnormalities was present in 8% of men and 4% of women. The severity of retinopathy was related in both sexes to higher fasting plasma glucose levels, higher systolic and diastolic blood pressure, lower serum insulin levels, and reduced beta-cell function. In addition, in men, increased alcohol consumption was related to increased severity of retinopathy, while leaner women had more severe eye lesions. Visual acuity was normal in most patients, but in men there was a trend for those with more severe retinal lesions to have worse visual acuity. Diabetic retinopathy is common in patients with newly diagnosed NIDDM. Careful ophthalmic assessment at diagnosis is important.
