RESUMO

Objective: To demonstrate the morpho-functional profile of the evaluation of patients with diabetic retinopathy without low severe visual acuity in a public hospital of reference in endocrinology, determining in this sample, the relation between the time of diabetes, age and visual acuity with the retinal thickness measured by the optical Coherence tomography (OCT) and fundus picture (FP). Materials and Methods: Prospective, linear study was carried through, in transversal cut of 61 consecutive patients with diabetic retinopathy registered in the HRT, and refered from the services of ophthalmology and endocrinology. Patients had been submitted to a complete ophthalmic evaluation including clinical history, visual acuity with correction and pin hole. The patients who had presented diabetic retinopathy, with transparent media, without previous surgery, nor previous Laser photocoagulation and with visual acuity better than 20/100 at snelen scale, had been included in the study. After the elimination of the patients who had not obeyed the inclusion/exclusion criteria 109 eyes of 55 patients then had been submitted the OCT and FP for evaluation of the presence or absence of edema by the FP and of the quantitative evaluation (measured of the retinal thickness of the 9 regions of the ETDRS), and of the qualitative evaluation (presence or absence of retinal edema for the central slit, number 1). Results/Conclusions: The average time of diabetes was of 12 years, varying of 23 to 86 years old. 51% were female, and 49% male. The OCT demonstrated discrete reduction of the retinal thickness with elapsing of the age. It did not have statistical significant correlation between the retinal thickness and the time of diabetes. The patients of the ophthalmology had greaters values of retinal thickness of what of the group of the endocrinology. The evaluation of the visual acuity improved with pin hole in 47% (51/109). The endocrinology group were 45% (23/50) of the eyes and the ophthalmology group were 55% (28/59). Only 22% (24/109) of the eyes presented corrected visual acuity of 20/20 with correction and without Diabetic Macular Edema (DME). In 83% (91/109) of the cases it had agreement and in 17% (18/109 eyes) it had discord in relation the presence/absence of DME in the profile of the morphologic evaluation carried through by the optic coherence tomography and the fundus picture, in the eyes of the amostral group.
