DSSSB Previous Year MCQs: Binocular Vision Watch the video lesson below and test your knowledge! Attempted0/5 Correct0 Wrong0 Accuracy0% Q-1: The Double Maddox test is done to measure: (2019) (DSSSB Optometrist Previous MCQs) a. Esodeviation b. Exodeviation c. Cyclodeviation d. Exophoria Answer: c. CyclodeviationThe Double Maddox rod test involves placing a red Maddox rod over one eye and a white one over the other to create two distinct parallel line images. By having the patient rotate the lenses until the two lines appear perfectly parallel, the clinician can accurately detect and quantify torsional misalignment known as cyclodeviation. Q-2: To neutralise a hypertropia, the prism should be positioned with: (2024) (DSSSB Optometrist Previous MCQs) a. Apex directed inferiorly b. Apex directed superiorly c. Base directed superiorly d. Base directed obliquely Answer: b. Apex directed superiorlyHypertropia is a vertical strabismus where the visual axis of the deviated eye points upward. To optically neutralize this deviation, a correcting prism must be placed with its base over the defect (base down), which fundamentally means the apex is directed superiorly. Q-3: Which of the following is NOT true about stereopsis? (2019) (DSSSB Optometrist Previous MCQs) a. It is measured in arc b. TNO test is based on monocular clues c. Frisby test is used after 4 years of age d. Lang test is used in young children Answer: b. TNO test is based on monocular cluesThe TNO test utilizes random-dot stereograms viewed through red-green anaglyph glasses to accurately assess binocular depth perception. Its specific design completely eliminates all monocular spatial clues, forcing the visual cortex to rely purely on bifoveal disparity to identify the hidden shapes. Q-4: What is the preferred management strategy for accommodative esotropia with a high AC/A ratio? (2024) (DSSSB Optometrist Previous MCQs) a. Progressive glasses b. Trifocal glasses c. Single vision glasses d. Polaroid glasses Answer: a. Progressive glassesAccommodative esotropia with a high AC/A ratio results in a significantly larger inward deviation at near than at distance. Progressive addition lenses or executive bifocals are the gold standard optical management, as they relax the excessive near accommodation and simultaneously eliminate the over-convergence. Q-5: In case of esodeviation during PBCT, the base is placed: (2019) (DSSSB Optometrist Previous MCQs) a. Base up b. Base down c. Base in d. Base out Answer: d. Base outThe Prism Bar Cover Test (PBCT) objectively measures the exact magnitude of a strabismic deviation. To neutralize an esodeviation, the clinician must place the optical prism with its thickest portion facing outward (base out) to manually shift the image onto the displaced fovea.
