Q-1: Lid retraction, lid lag, and proptosis are commonly seen in which ocular condition? (2024) (DSSSB Optometrist Previous MCQs)
a. Ptosis
b. Ocular Grave’s disease
c. Exotropia
d. Myopia
Answer: b. Ocular Grave’s disease
Ocular Grave’s disease, or Thyroid Eye Disease (TED), is an autoimmune condition that causes inflammation and swelling of the extraocular muscles and orbital fat. This increased orbital volume physically pushes the globe forward (proptosis) and leads to classic signs like upper eyelid retraction (Dalrymple’s sign) and lid lag on downgaze (Von Graefe’s sign).

Q-2: Which of the following is NOT a sign of 3rd nerve palsy? (2019) (DSSSB Optometrist Previous MCQs)
a. Ptosis
b. Ipsilateral mydriasis
c. Ptosis increases in the evening
d. Defective accommodation
Answer: c. Ptosis increases in the evening
A true oculomotor (third cranial nerve) palsy typically presents with a constant, severe ptosis alongside an unreactive dilated pupil and a “down and out” eye deviation. Ptosis that progressively worsens toward the evening due to muscle fatigue is a classic hallmark of myasthenia gravis, a neuromuscular junction disorder, rather than a cranial nerve palsy.

Q-3: In which of the following conditions the corneal sensations are lost? (2019) (DSSSB Optometrist Previous MCQs)
a. Herpes simplex keratitis
b. Fungal keratitis
c. Bacterial keratitis
d. Marginal keratitis
Answer: a. Herpes simplex keratitis
Herpes simplex virus is highly neurotropic, meaning it actively invades and travels along the ophthalmic division of the trigeminal nerve. A classic clinical hallmark of herpetic ocular infection is a significant reduction or complete loss of corneal sensitivity due to the direct viral damage to the subepithelial nerve plexus.

Q-4: Which is the most common cause of diminished vision in diabetic retinopathy? (2019) (DSSSB Optometrist Previous MCQs)
a. Microaneurysm
b. Macular edema
c. Retinal hemorrhage
d. Retinal detachment
Answer: b. Macular edema
While microaneurysms and retinal hemorrhages are classic signs of diabetic retinopathy, they often occur in the peripheral retina without immediately affecting central visual acuity. Diabetic macular edema involves the leakage of fluid and lipid exudates directly into the macula, making it the leading cause of moderate to severe vision loss in diabetic patients.

Q-5: Which of the following is an inflammatory ocular condition? (2024) (DSSSB Optometrist Previous MCQs)
a. Exotropia
b. Optic Atrophy
c. Keratitis
d. Poliosis
Answer: c. Keratitis
Keratitis refers directly to the inflammation of the cornea, which can be infectious or non-infectious in origin. The other conditions listed are structural (exotropia), degenerative (optic atrophy), or pigmentary (poliosis) rather than primarily inflammatory processes.
