Explanation: Gonioscopy is a procedure commonly used to assess the anterior segment of the eye, specifically the drainage angle. It involves the use of a specialized contact lens called a gonioscope, which is placed on the eye to visualize the angle between the cornea and the iris. Gonioscopy is particularly important in the evaluation and management of glaucoma. Therefore, the correct answer is D) Gonioscopy.

It involves the use of a specialized contact lens call olens, which is placed on thesurface of the eye to visualize and assess age angle. Gonioscopy is crucial in evaluating and managing conditio as glaucoma, as it provides important information about the angle tures and helps determine the appropriate treatment approach.

Pinhole test Answer: C
Explanation: Visual acuity, which measures the sharpness and clarity of vision, can be assessed using various techniques. The Snellen chart is a commonly
used method that involves the patient reading letters or symbols from a chart placed at a specific distance. The Jaeger Near chart is used to assess near vision, particularly for reading and close-up tasks. The pinhole test involves the patient looking through a small hole, which can improve visual acuity by reducing the effects of refractive errors. Therefore, all of the options (A, B, and
C) are correct methods for assessing visual acuity.

anation: The Amsler Grid is a diagnostic tool used to evaluate the fun macula, which is the central part of the retina responsible for detaile
n. It consists of a grid of horizontal and vertical lines with a central ion point. The patient is asked to look at the grid and report any rtions, missing areas, or abnormalities in the grid's pattern. Changes i arance of the grid can indicate macular conditions such as macular neration or macular edema.

Intraocular Surgery. Cataract Extractions. Glaucoma Surgery. Foreign Body Removal. Answer: D gn objects that may have entered the eye, such as metal fragments, cles, or debris. Prompt removal of foreign bodies is crucial to prevent er damage and potential infection. Therefore, the correct answer is D) ign Body Removal. ch diagnostic test is used to evaluate macular function? isual Field. ereopsis. msler Grid. uscle Function. wer: C parti furth Fore Whi V St A M Ans Explanation: The Amsler Grid is a diagnostic tool used to evaluate macular function. It consists of a grid of intersecting lines with a central fixation point. Patients with macular disorders may experience distortions or gaps in the grid when viewing it. The Amsler Grid is particularly useful in assessing central visual field defects and detecting early signs of macular degeneration. Therefore, the correct answer is A) Amsler Grid. Which type of procedure is commonly used to assess tear function? Angiography. Tonometry. Schirmer Test. wer: C anation: The Schirmer test is a commonly used procedure to assess te ion. It measures the quantity of tears produced by the lacrimal glands. est, a small strip of filter paper is placed in the lower eyelid, and the t llowed to wick up the paper. The length of wetting on the paper is ured after a specified time. The Schirmer test helps evaluate tear uction and diagnose conditions such as dry eye syndrome. Therefore, ct answer is D) Schirmer Test. ch diagnostic test is commonly used to assess the curvature of the cor achymetry eratometry onioscopy Expl ar funct In this t ears are a meas prod the corre Whi nea? P K G Exophthalmometry Answer: B Explanation: Keratometry is a diagnostic test used to assess the curvature of the cornea, which is the clear front surface of the eye. It measures the corneal curvature by focusing on the reflection of light from the cornea. Keratometry is commonly used to evaluate corneal astigmatism and to aid in the fitting of contact lenses or the planning of refractive surgeries. phthalmic Photography. ltrasound. pecular Microscopy. unduscopy. wer: D anation: Funduscopy, also known as direct ophthalmoscopy, is a proc monly used for direct visualization of the retina. It involves the use of held instrument called an ophthalmoscope, which allows the healthcar ider to examine the internal structures of the eye, including the retina, and blood vessels. Funduscopy is important in the assessment and agement of various retinal conditions and diseases. Therefore, the corr er is C) Funduscopy.
