Written answer 33 Which VA abbreviation indicates without correction? Written answer 34 Which scenario requires reporting ‘E’ chart usage? a Color chart b Ring chart c Pediatrics d Landmark chart 35 Which distance VA testing method uses a projector and occluder? a Color vision test b Ophthalmoscopy procedure c Distance Visual Acuity d Near Visual Acuity 36 Which metric is used to describe visual angle? a Degrees or minutes of arc b Radians c Pascals d Liters 37 Which VA term indicates with correction? Written answer 38 What is the consequence of a patient reading one line incorrectly? a Document entire chart unreadability b All lines are invalid c That line is not considered readable; record last readable line d Skip recording Feedback 1 Snellen chart is standard for distance VA 2 20/20 indicates normal acuity at 20 ft; the denominator differs for comparison. 3 Always start with the OD before OS in VA testing. 4 CF denotes Count Fingers 5 HM means the patient can perceive hand movement but not letters. 6 NLP is recorded when no light is perceived; document and continue as appropriate. 7 Pinhole helps separate refractive error from other pathology. 8 NLP = No Light Perception; used when light is not perceived. 9 NVA denotes Near Visual Acuity; separate from distance VA. 10 Distance VA is typically tested at 20 feet; meters are used for conversion. 11 cPH = with pinhole; used after pinhole testing. 12 Chair color is not a VA factor; lighting and optics are. 13 Occlusion ensures monocular VA is measured without binocular influence. 14 Record the lowest line read with more than half correct. 15 F&F indicates infant tracking of a bright object; other methods differ. 16 Improper illumination can degrade test accuracy. 17 Snellen meters to feet conversions use proportional math; example 6/6 = 20/20. 18 OD/OS/OU denote right/left/both eyes acuity. 19 Record the last line where half or more of optotypes were read correctly. 20 PH relates to pinhole testing context. 21 Near VA uses closer reading distances (e.g., 14 inches). 22 LP indicates perception of light presence. 23 Pediatric VA requires reassurance and engagement. 24 Numerator indicates the test distance (e.g., 20 ft). 25 VAsc = Distance Visual Acuity with correction. 26 D indicates distant acuity in records. 27 If 20/20 not read, use pinhole or other modalities as per protocol. 28 Meters are used in Snellen format; 6/6 corresponds to 20/20 feet. 29 If hand motion is perceivable, report HM (not LP/NLP). 30 Binocular VA is used in specific situations, such as nystagmus. 31 Conversions between meters and feet involve changing units/denominators. 33 sc stands for Without Correction. 34 E Chart is common for basic or pediatric VA. 35 Distance VA testing uses a Snellen chart with projector/occluder setup. 36 Visual angle is given in degrees or minutes of arc. 37 cc = with correction; sc = without correction. 38 Only lines read with majority correctness count.
