“…On one hand, several studies demonstrated abnormal flash fullfield and foveal ERGs in various retinal vasculopathies 21,27,28 and choroidal perfusion abnormalities. 29 On the other hand, a previous finding of reduced oscillatory potentials in eyes with glaucoma, 1 similar to reductions found in diabetic vasculopathy 30 and central retinal vein occlusion 31 can be consistent with underlying vascular insufficiency in some eyes with glaucoma.…”

ResumenObjetivo: Predecir el resultado visual posoperatorio en pacientes con desprendimiento de retina traccional complejo y grave deterioro visual. Material y métodos: Se realizó electrorretinograma preoperatorio a pacientes a quienes se les realizó vitrectomía vía pars plana traocular. Resultados: Se incluyeron en el estudio 9 ojos de 9 pacientes, los cuales fueron seguidos durante 6 meses. En ningún paciente se logró mejoría en la agudeza visual (AV) posoperatoria y en 3 pacientes (33.4%) a los 6 meses se produjo empeoramiento visual, 6 pacientes (66.66%) permanecieron con AV preoperatoria y posoperatoria a los 6 meses sin cambios. En todos los pacientes se obtuvieron respuestas abolidas en el electrorretinograma estandarizado preoperatorio. Conclusiones: El electrorretinograma como examen preoperatorio en pacientes con desprendimiento de retina traccional diabético y AV sumamente comprometida, permite predecir el mal resultado visual posoperatorio. Electroretinogram standardized in patients undergoing vitrectomy by advanced proliferative diabetic retinopathy AbstractObjective: Predicting postoperative visual outcome in patients with complex tractional retinal detachment and severe visual impairment. Material and methods: Electroretinogram was performed preoperatively to patients who unResults: Nine eyes of nine patients were followed for six months. No patient achieved improvement in postoperative visual acuity. In three patients (33.4%) at six months, visual worsening occurred, six patients (66.66%) remained with preoperative visual acuity and postoperative at

“…The fmacERGs are elicited by focal stimuli centered on the macula with [15][16][17] and without [18][19][20] a bright background illumination. Studies using the conventional fmacERGs [19] and mfERGs [14,[21][22][23] techniques have demonstrated that the OPs are not uniformly distributed in the macular area.…”
