What is the most appropriate test to confirm a diagnosis in a patient presenting with gradual vision loss in the left eye, visual acuity of 20/20 in the right eye and 20/100 in the left, with normal ocular examination findings and suspected malingering? Testing for involuntary eye movement using optokinetic stimuli Using a reflective surface to evaluate fixation response with the unaffected eye covered Placing a prism with base-up in front of the left eye while the patient reads with both eyes open Performing a refraction with fogging lenses None 2. Which of the following statements about the visual evoked response (VER) is incorrect? VER is an electrical signal extracted from the electroencephalogram (EEG). Stimuli for VER include white light flashes or patterns presented transiently or through pattern reversal. Key parameters for functional evaluation are the amplitude of the first positive wave and its latency. Flash VER is commonly used to assess visual acuity in preverbal children and is reliable for detecting factitious visual loss. None 3. Which of the following findings is LEAST likely to be associated with Cancer-Associated Retinopathy (CAR)? Abnormal full-field ERG with reduced a- and b-wave amplitudes. Cystic spaces and loss of the ellipsoid layer on OCT. Optic disc swelling in the early stages of the disease Peripheral visual field deficits and nyctalopia. None 4. A patient with MAR undergoes full-field ERG. Which of the following findings is most consistent with this condition? Delayed photopic and scotopic implicit times Reduced photopic b-wave with normal scotopic a-wave Normal a-wave and severely reduced b-wave in dark-adapted conditions Absence of both photopic and scotopic responses None 5. Which of the following is true about Cancer-associated Retinopathy (CAR)? ERG findings are normal. The tumor expresses an antigen homologous to recoverin, a 23-kd calcium-binding protein. Breast cancer is the most common associated malignancy. Vision loss is stationary. None You have reached the end of this quiz. Please click the Submit button to view the result.
