Valor esperado del grosor foveal en mexicanos diabéticos con edema macular

摘要: Background: The tomographic cut-off point to detect macular edema uses an international reference of retinal thickness, which is greater than that in our population. We undertook this study identify the expected value central subfield mean thickness (CSMT) Mexican patients with diabetes clinically significant (CSME) and proportion using only for clinical (>300 µm) could overlook diagnosis. methods: carried out observational, analytical, crosssectional prospective study. Eyes diabetic CSME (January 2006-June 2007) a fluorescein angiography optical coherence tomography were included. sample was divided according angiographic type: monofocal (group 1), multifocal 2), or diffuse 3). CSMT each group weighed by represented calculate all-type value. eyes ≤300 µm identified. results: Ninety three Mean age 60.9 years; there 57 females (61.3%). Forty one assigned 1 (44.1%, 210.63 µm), 31 2 (33.3%, 279.65 21 3 (22.6%, 327.14 µm). 259.9 µm, 37.75% over normal population 23% American reference. <300 79.6% (95% CI 71.4-87.8). Conclusions: within range internationally regarded as subclinical. Using local references recommended avoid overlooking diagnosis overestimating its treatment effect.
