NEET-PG 2017 - Ophthalmology PYQs Practice Questions

Q: Which of the following is correct about the image shown? (Recent NEET Pattern 2016-17)

A = Kayser Fleischer ring, B = Arcus senilis. ***A = Kayser Fleischer ring, B = Arcus senilis*** - Image A displays a **Kayser-Fleischer ring**, a greenish-brown ring in the periphery of the cornea, characteristic of **Wilson's disease** due to copper deposition. - Image B shows **arcus senilis**, a milky-white or grayish ring around the cornea, which is a **common age-related change** due to lipid deposits, and can appear at any age. *A = Arcus senilis, B = Kayser-Fleischer ring* - This option incorrectly identifies the lesions; the ring in image A is associated with copper deposition, not lipid deposition. - The ring in image B is clearly a common lipid ring often seen in older individuals, contrasting with the distinct appearance of a Kayser-Fleischer ring. *A = Arcus senilis, B = Hudson-Stahli line* - Image A does not show arcus senilis; its color and location are consistent with copper deposition. - Image B does not depict a Hudson-Stahli line, which is a thin, brownish-linear deposit of iron in the corneal epithelium, typically horizontal and not circumferential. *A = Hudson-Stahli line, B = Arcus senilis* - Image A's appearance, as a circumferential greenish-brown deposit, is not consistent with a linear Hudson-Stahli line. - While image B correctly identifies arcus senilis, the identification of A as a Hudson-Stahli line is incorrect.

Q: A 3-year-old girl brought with swelling in left eye which had shown rapid growth in last 4 weeks. On examination it is a bulbous fleshy mass about 5 x 4 cm arising from lower eyelid. No organomegaly or was noted and lymph node examination was unremarkable. The Complete blood counts are normal. Probable diagnosis is?

Rhabdomyosarcoma. ***Rhabdomyosarcoma*** - This is the most common **primary orbital malignancy in children**, often presenting as a rapidly growing, fleshy periorbital mass, consistent with the 3-year-old girl's symptoms. - The rapid growth (4 weeks) and the description of a **bulbous, fleshy mass** arising from the eyelid are classic presentations of rhabdomyosarcoma. *Retinoblastoma* - This is a malignancy of the retina and typically presents with **leukocoria (white pupillary reflex)**, strabismus, or vision impairment, not usually as an external fleshy mass arising from the eyelid. - While it is a common pediatric eye tumor, its clinical presentation differs significantly from the described external swelling. *Chloroma* - Also known as granulocytic sarcoma, chloroma is an extramedullary manifestation of **acute myeloid leukemia** and would typically be associated with systemic symptoms of leukemia (e.g., anemia, thrombocytopenia, leukocytosis/leukopenia) and abnormal blood counts. - The patient's normal CBC and lack of organomegaly/lymphadenopathy make chloroma less likely. *Orbital metastasis* - While possible, orbital metastases in children are rare and typically arise from **neuroblastoma** or occasionally other primary tumors. - Such metastases usually present with features suggestive of the primary tumor, which are not mentioned here.

Q: The following alphabet of Snellen's chart will subtend an angle of how many minutes at nodal point of the eye?

5. ***Correct Option: 5 minutes*** - The **entire optotype (letter)** of a Snellen's chart subtends an angle of **5 minutes of arc** at the nodal point of the eye when viewed from the standard testing distance - This is the fundamental design principle of the Snellen chart for visual acuity testing - At 6 meters (20 feet), a letter on the 6/6 (20/20) line subtends 5 minutes of arc in total height and width - This standardization allows for consistent visual acuity measurement across different testing scenarios *Incorrect: 1 minute* - This is the angle subtended by **each component part** of the letter (e.g., the width of a stroke or gap between strokes) - Not the angle for the entire letter - Used to define the detail that must be resolved for normal vision *Incorrect: 3 minutes* - No standard optical principle supports this value - Not related to Snellen chart design parameters *Incorrect: 10 minutes* - This angle is too large for standard Snellen chart optotypes - Would indicate significantly reduced visual acuity requirements - Not consistent with 6/6 (20/20) vision standards [Practice more Ophthalmology PYQs on OnCourse]

Q: The chart shown in the image is:

Snellen's chart. ***Snellen's chart*** - The image displays a series of rows with **optotypes (letters)** that decrease in size, which is characteristic of a **Snellen chart**. - This chart is specifically used to measure **visual acuity** by determining the smallest row of letters a person can read at a specific distance. *Ishihara's chart* - **Ishihara charts** are used to test for **color blindness** and consist of plates with colored dots that form numbers or patterns, which are not depicted in the image. - The chart shown focuses on letter recognition and size differentiation, not color perception. *Farnsworth-Munsell hue test* - The **Farnsworth-Munsell hue test** is used for precise **color discrimination** and involves arranging caps of varying hues in a continuum. - This test is distinct from the letter-based visual acuity chart shown in the image. *Pelli-Robson chart* - The **Pelli-Robson chart** is used to measure **contrast sensitivity**, presenting letters of a constant size but decreasing contrast. - While it uses letters, the chart in the image has letters of decreasing size, indicating a visual acuity test rather than contrast sensitivity.

Q: Identify the stain instilled in the eye in the following image:

Fluorescein stain. ***Fluorescein stain*** - The image shows a **green-yellow fluorescence** under cobalt blue light, which is characteristic of **fluorescein dye** pooling in areas of epithelial defect or healthy tear film. - Fluorescein is a commonly used diagnostic dye in ophthalmology to visualize **corneal abrasions**, ulcers, or contact lens-related issues as it stains damaged corneal epithelial cells. *Rose Bengal stain* - **Rose Bengal** stains devitalized epithelial cells and mucus a **red or purple color**, not green or yellow. - It is particularly useful for identifying **dry eye syndrome** and herpes simplex keratitis but would appear distinctly different from the image. *Lissamine green stain* - **Lissamine green** stains damaged or devitalized conjunctival and corneal cells a **blue-green color**, similar to Rose Bengal. - While it has a greenish hue, it typically does not fluoresce and produces a distinct staining pattern different from the bright, uniform green seen with fluorescein under blue light. *Rhodamine stain* - **Rhodamine** dyes, which are typically **red or pink fluorescent**, are not routinely used as a standard ophthalmic stain for general corneal evaluation. - Its spectral properties and clinical applications are distinct from the common diagnostic dyes used on the ocular surface.
