Abstract

Purpose : To assess the prevalence of peripheral neuropathy findings in patients diagnosed with diabetic retinopathy (DR) for over 5 years having follow up care in Medical Retina (MR) clinic.

Methods : Thirty-three patients were invited randomly and consecutively evaluated in one day in our MR clinic. Along with indirect ophthalmoscopy to evaluate the patients’ retinas, various tests to assess the presence and severity of peripheral neuropathy were performed. Semmes-Weinstein monofilament test, abnormalities in posterior tibial and dorsalis pedis pulse, presence of active or inactive diabetic foot ulcers (DFUs), and questions such as history of DFUs or inadequate outdoor footwear were made throughout the examination. The results were, then, correlated.

Results : Among mild, moderate and severe retinopathy patients: 39,4% presented abnormal Semmes-Weinstein monofilament test; 42,5% and 30,3% showed weak or absent pulse (posterior tibial and dorsalis pedis respectively); While 24,2% reported history of diabetic foot ulcer, only 9,1% demonstrated active DFUs and 3% had amputation history. The inadequate outdoor footwear use was reported by 39,4% of the patients.

Conclusions : Peripheral neuropathy is a common manifestation of diabetes in patients diagnosed with diabetic retinopathy for over 5 years undergoing clinical follow-up in a MR clinic. Therefore, we may infer that, being two of the three most common diabetes manifestations, diabetic retinopathy may be a biomarker for peripheral neuropathy in diabetic patients. Furthermore, patients presenting peripheral neuropathy from diabetic foot that were never submitted to a fundoscopic evaluation have a good chance of presenting undiagnosed diabetic retinopathy.
