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.
