Abstract: The Esterman program should be used for driving visual field assessments, and may be performed as a binocular or monocular test dependent on the patient’s visual acuity in either eye. A monocular Esterman test is suitable for monocular drivers and a binocular Esterman test is recommended for all binocularly sighted drivers. The monocular and binocular program assesses 100 and 120 points respectively. The target size is equivalent to a size III Goldmann target and the target intensity is 10 decibels. Esterman program should be performed with drivers’ typical prescription which they use for driving. Results are presented in printout including personal and instrumental information, reliability indices, a coding map, numbers of the seen and no seen points, Esterman efficacy score. Also in the binocular Esterman test, the patient’s fixation as part of the reliability indices should check by the practitioner during the test. The minimum field of vision for safe driving is defined as a field of at least 120 degrees on the horizontal that there should be no significant field defect within 20° of fixation either above or below the horizontal meridian and that there should be no significant scotoma close to fixation. It also reduces the risk of the Esterman visual field testing in drivers with advanced retinal and visual pathway diseases such as glaucomatous in severe stages and Homonymous or bitemporal defects to prevent accidents caused by efficient visual field.
