Q-1
Which of the following bones do NOT make up the bony orbit? (DSSSB Optometrist Previous Year Question Paper)
👆 Click an option to check your answer
✓ Correct Answer: D. Parietal
The bony orbit is composed of seven bones: Maxilla, Frontal, Zygomatic, Ethmoid, Lacrimal, Sphenoid, and Palatine. The Parietal bone forms the upper-lateral vault of the cranium and does not extend into the orbital cavity.
Q-2
The volume of an adult bony orbit is: (DSSSB Optometrist Previous Year Question Paper)
👆 Click an option to check your answer
✓ Correct Answer: A. 30 ml
The average volume of a fully developed human bony orbit is approximately 30 millilitres. This compact space houses the globe, extraocular muscles, orbital fat, and neurovascular structures. Options B, C, and D are all too large — a common exam trap.

Q-3
The structures passing through the superior orbital fissure are:(DSSSB Optometrist Previous Year Question Paper)
👆 Click an option to check your answer
✓ Correct Answer: B
The superior orbital fissure transmits: CN III (oculomotor), CN IV (trochlear), CN VI (abducens), the ophthalmic branch of V1, and the superior ophthalmic vein. The ophthalmic artery does NOT pass here — it enters through the optic canal with CN II.
Q-4
The opening of the nasolacrimal duct in the nose is at:(DSSSB Optometrist Previous Year Question Paper)
👆 Click an option to check your answer
✓ Correct Answer: B. Inferior meatus
The nasolacrimal duct drains tears from the lacrimal sac into the nasal cavity. It terminates beneath the inferior nasal concha, in the area called the inferior meatus. The middle meatus drains the paranasal sinuses — a common confusion.

Q-5
The vertical and horizontal anterior diameter, respectively, of cornea in adults is:(DSSSB Optometry MCQs with Answers)
👆 Click an option to check your answer
✓ Correct Answer: A. About 11 and 12 mm
The adult cornea is slightly elliptical. Vertical diameter ≈ 11 mm, Horizontal diameter ≈ 12 mm. The cornea is wider horizontally. Option B reverses the values — the most common trap in this question.
Q-6
How many layers are there in the neurosensory retina?(DSSSB Optometry MCQs with Answers)
👆 Click an option to check your answer
✓ Correct Answer: A. 9 layers
Total retina = 10 layers. The outermost is the Retinal Pigment Epithelium (RPE). The remaining 9 inner layers = neurosensory retina. When the question specifically asks “neurosensory retina,” the answer is 9, not 10.

Q-7
Which tissue of the eye is called the suspensory ligament of Lockwood? (DSSSB Optometry MCQs with Answers)
👆 Click an option to check your answer
✓ Correct Answer: A. Fascia bulbi
The suspensory ligament of Lockwood is a hammock-like structure derived from the lower part of the fascia bulbi (Tenon’s capsule). It provides structural support to the globe, preventing inferior displacement of the eye within the orbit.
Q-8
How many extraocular muscles are present in the human eye? (DSSSB Optometrist Solved Papers PDF)
👆 Click an option to check your answer
✓ Correct Answer: B. Six
Each eye has 6 extraocular muscles: 4 rectus muscles (superior, inferior, medial, lateral) and 2 oblique muscles (superior oblique and inferior oblique). All 6 produce coordinated, precise eye movements.

Q-9
On which day do the optic pits form in a developing embryo?(DSSSB Optometrist Solved Papers PDF)
👆 Click an option to check your answer
✓ Correct Answer: D. Day 22
Optic pits are the earliest precursors of the eye, forming on Day 22 of embryonic development. They invaginate → optic vesicles → optic cups → retina and other ocular structures. This embryology topic appeared NEW in the DSSSB 2024 paper.
Q-10
Where do the stroma and blood vessels of the iris develop from?(DSSSB Optometrist Solved Papers PDF)
👆 Click an option to check your answer
✓ Correct Answer: D. Vascular mesenchyme
The stroma and blood vessels of the iris develop from vascular mesenchyme (neural crest cells). The neural ectoderm contributes to the pigmented layers. This iris embryology topic was new in the 2024 DSSSB paper — expect similar questions in 2026.
