Q-2: Strabismic amblyopia is more common in patients with: (BFUHS Optometry Previous Year Question Paper)
A) Intermittent squint
B) Alternate squint
C) Constant squint
D) Latent squint
Click “Show more” to see the answer and explanation.
Answer: C) Constant squint
Constant squint disrupts binocular vision, leading to amblyopia due to suppression of the deviated eye. Intermittent and alternate squints are less likely to cause amblyopia as the eye gets visual input periodically.

Q-3: In worth’s 4 dot test, patient with Right eye suppression will see: (BFUHS Ophthalmic Officer Previous Year MCQs)
A) 2 dots
B) 3 dots
C) 4 dots
D) 5 dots
Click “Show more” to see the answer and explanation.
Answer: B) 3 dots
In the Worth 4 Dot test, the right eye views through a red filter and the left eye through a green filter. If the right eye is suppressed, the patient will fail to see the lights filtered for that eye and only perceive the three green lights visible to the left eye.

Q-4: In paralytic squint: (BFUHS Optometry Previous Year Question Paper)
A) Primary deviation is more than Secondary deviation
B) Primary deviation is equal to Secondary deviation
C) Primary deviation is less than Secondary deviation
D) Secondary deviation is absent
Click “Show more” to see the answer and explanation.
Answer: C) Primary deviation is less than Secondary deviation
In paralytic squint, the deviation is larger when the paretic eye is used for fixation (secondary deviation). This phenomenon occurs due to Hering’s Law, where excessive innervation required to move the paralyzed muscle is simultaneously sent to the yoke muscle of the healthy eye.

Q-5: Binocular single vision is present since birth? (BFUHS Ophthalmic Officer Previous Year MCQs)
A) True
B) False
C) Don’t understand
D) Maybe
Click “Show more” to see the answer and explanation.
Answer: B) False
Binocular single vision is not present at birth; it is an acquired reflex that develops during the first few months of life. Newborns often exhibit uncoordinated eye movements, with fusion typically beginning to solidify around 3 to 6 months of age.

B) 3
C) 4
D) 5
Click “Show more” to see the answer and explanation.
Answer: D) 5
A patient with manifest strabismus who is not suppressing will experience diplopia, seeing the 2 red dots and 3 green dots as separate images. This results in a total of 5 dots, confirming the presence of diplopia without suppression.

Q-8: Grade 2 of Binocular Vision is: (BFUHS Ophthalmic officer Previous Year Question Paper)
A) Stereopsis
B) Perception
C) Fusion
D) None of the above
Click “Show more” to see the answer and explanation.

Q-9: The Prism Bar Cover Test is used to evaluate: (BFUHS Ophthalmic Officer Previous Year MCQs)
A) Visual acuity
B) Squint
C) Corneal curvature

Q-10: In Concomitant squint: (BFUHS Ophthalmic Officer Previous Year MCQs)
A) Primary deviation > secondary deviation
B) Primary deviation < secondary deviation
C) Primary deviation = secondary deviation
D) None of the above
Click “Show more” to see the answer and explanation.
Answer: C) Primary deviation = secondary deviation
In concomitant squint, the deviation remains equal regardless of which eye is fixing (primary = secondary deviation). This distinguishes it from paralytic squint where deviations differ.
.
Q-11: How many grades of Binocular vision are there? (BFUHS Ophthalmic Officer Previous Year MCQs)
A) 1 grade
B) 2 grades
C) 3 grades
D) 4 grades
Click “Show more” to see the answer and explanation.
Answer: C) 3 grades
Classically, binocular single vision is categorized into three grades: Grade I (Simultaneous Perception), Grade II (Fusion), and Grade III (Stereopsis). This hierarchical classification represents progressive levels of binocular function.

Q-12: In worth’s 4 dot test, patient with Abnormal Retinal Correspondence will see: (BFUHS Optometry Previous Year Question Paper)
A) 2 dots
B) 3 dots
C) 4 dots
D) 5 dots
Click “Show more” to see the answer and explanation.
Answer: C) 4 dots
A patient with Abnormal Retinal Correspondence may report seeing 4 dots despite having a manifest strabismus. This occurs because the brain has adapted to fuse images from non-corresponding retinal points, mimicking a normal fusion response.

Q-11: Which of these help in visualization of corneal cells?
A Confocal microscope
B Optical coherence tomography
C Pachymeter
D Slit lamp biomicroscope
Answer: A) Confocal microscope
A confocal microscope allows detailed, in vivo imaging of corneal cells, including endothelial and epithelial layers. It provides high-resolution cellular-level imaging essential for diagnosing corneal pathologies.
Q-12: Which are not the uses of single or double frequency Nd:YAG laser?
A Spectacle removal
B Laser iridotomy
C Pan retinal photocoagulation in diabetic retinopathy
D Ablation of posterior capsular opacification
Answer: A) Spectacle removal
Nd:YAG lasers are used for iridotomy, posterior capsular opacification ablation, and sometimes diabetic retinopathy treatment. They cannot be used for spectacle removal, which requires refractive surgery like LASIK.
Q-13: Slit lamp biomicroscope cannot be used for which of the following:
A Measurement of corneal epithelial defect
B Observing the optic disc and macula with 90D lens
C Laser iridectomy in angle closure glaucoma
D Fluorescein staining with cobalt blue light
Answer: C) Laser iridectomy in angle closure glaucoma
A slit lamp is a diagnostic tool and cannot perform surgical procedures like laser iridectomy. Such procedures require specific laser devices designed for therapeutic interventions.
Q-14: Gold standard for measurement of IOP is:
A Digital tonometry
B Schiotz tonometry
C Pneumotonometry
D Applanation tonometry
Answer: D) Applanation tonometry
Goldmann Applanation Tonometry is widely regarded as the gold standard for measuring intraocular pressure. It works by measuring the force required to flatten a fixed area of the cornea and is considered the most accurate method for glaucoma diagnosis and management.
Q-15: Which laser is used in the management of after-cataract?
A Argon
B Krypton
C Nd:YAG
D Excimer
Answer: C) Nd:YAG
The Nd:YAG laser is the standard tool used for posterior capsulotomy to disrupt opacified posterior capsule. This restores clear vision in patients who develop after-cataract following cataract surgery.
Q-16: Instrument used to measure phoria for near (33 cm) is:
A Maddox rod
B Maddox wing
C RAF rule
D None of the above
Answer: B) Maddox wing
The Maddox wing is specifically designed for measuring heterophoria at near distance (typically 33 cm). It uses a combination of red and white lights with a dissociating effect to quantify the deviation.
Q-17: Auto-refractometer is a method of refraction:
A Subjective
B Objective
C Both of the above
D None of the above
Answer: B) Objective
Auto-refractometry is an objective method of refraction that measures the eye’s refractive error without requiring patient responses. It provides a reliable starting point for subjective refraction.
Q-18: Jackson’s cross cylinder is used to check:
A Axis of the cylinder
B Power of the cylinder
C Both of the above
D None of the above
Answer: C) Both of the above
The Jackson Cross Cylinder is used to refine both the axis and power of the cylindrical correction during subjective refraction. It allows precise adjustment of astigmatic correction by presenting two alternative lens positions.
Q-19: Keratometry measures:
A Retinal thickness
B Corneal curvature
C Lens power
D Visual fields
Answer: B) Corneal curvature
Keratometry measures the radius of curvature of the anterior corneal surface. This measurement is essential for contact lens fitting, IOL power calculation, and diagnosing corneal conditions like keratoconus.
Q-20: Which instrument is used to measure intraocular pressure?
A Perimeter
B Retinoscope
C Tonometer
D Ophthalmoscope
Answer: C) Tonometer
A tonometer is the instrument used to measure intraocular pressure, with Goldmann Applanation Tonometry being the gold standard. Regular IOP measurement is essential for glaucoma diagnosis and management.
