Electroretinography (ERG) is an objective test that evaluates the retinal function. This paper wants to present to the veterinary Romanian scientific community the importance of using this diagnostic tool for clinicians dealing with blind patients. Candidates for ERG were selected from ophthalmological patients presented with blindness because it was difficult to establish a definitive diagnosis using only ophthalmological examination. All patients underwent general anesthesia. ERG was performed using the HMsERG unit, with preprogrammed included protocols. The protocols used in this study were Short protocol for the cataract surgery candidates and ISCEV protocol for the other patients. ERG confirmed the results obtained on chromatic pupillary light reflex evaluation. ERG proved useful in the following cases: diagnosing retinal inherited disorders, differentiating between retinal and postretinal causes of blindness, evaluation of retinal function in cataract surgery candidates. ERG objectively assesses the retinal function and should be used on a scale by practitioners dealing with blind patients.
