Show less 29. One may perform poorly on a stereopsis test if a) Suppression of one eye b) Unequal retinal image quality in the two eyes c) Amblyopia d) All of the above Click "Show more" to see the answer and explanation. Show more Ans: d) All of the aboveExplanation:Stereopsis, or depth perception, requires proper binocular vision. Conditions like suppression, unequal retinal images (anisometropia), and amblyopia (lazy eye) can all affect stereopsis performance. Show less 30) A patient's manifest refraction in BE: -2.50DS. His PRA was found to be 6.50DS without correction. What is his amplitude of accommodation? a) 4.00D b) 5.00D c) 5.50D d) 6.50D Click "Show more" to see the answer and explanation. Show more Ans: d) 6.50DTo get AOA from PRA we can use the formula: AOA = PRA (without minus sign) + 2.50Here PRA is 6.5D without correction. So actual PRA after subtraction of correction will be: 6.5 – 2.50 or 4.5D.So, AOA will be AOA = 4.5 + 2.5 or 6.5D Show less 31) A patient's manifest refraction in BE: -2.00DS. Sustained blur was reported while adding minus lenses with -6.00DS. What is his amplitude of accommodation? A) 6.00D B) 6.50D C) 8.00D D) 8.50D Click "Show more" to see the answer and explanation. Show more Ans: B) 6.50DExplanation:To get AOA from PRA we can use the formula: AOA = PRA (without minus sign) + 2.50Here PRA is 6.0 without correction. So, actual PRA after subtraction of correction will be: 6.0 – 2.00 or 4.0D.So, AOA will be AOA = 4.0 + 2.5 or 6.5D Show less 32) Three in one CL solution except a) Optifree b) Aqua lens c) Doxysept Click "Show more" to see the answer and explanation. Show more Ans: c) DoxyseptExplanation:"Three in one" solutions are used for cleaning, disinfecting, and storing contact lenses.

Show less 33) Suitable low vision aid for a patient with weak hand a) Stand Magnifier. b) Hand Magnifier c) Spectacle Magnifier Click "Show more" to see the answer and explanation. Show more Ans: c) Spectacle MagnifierExplanation:Spectacle magnifiers are hands-free and are ideal for patients with weak hands or limited dexterity, unlike hand-held magnifiers that require manual handling. Show less 34. Fifth nerve palsy could cause: a. Ptosis. b. Proptosis. c. Neuropathic keratopathy. d. Lagophthalmos. Click "Show more" to see the answer and explanation. Show more Answer: c. Neuropathic keratopathy.Explanation:The fifth cranial nerve, also known as the trigeminal nerve, is responsible for sensation in the face, including the cornea. When the trigeminal nerve is affected, it can lead to neuropathic keratopathy (also known as neurotrophic keratopathy). This condition is characterized by a reduction or loss of corneal sensation, leading to impaired healing, corneal ulcers, and in severe cases, corneal perforation. Show less 35. After 48 hours of a cataract extraction operation, a patient complained of ocular pain and visual loss. On examination, this eye looked red with ciliary injection, corneal oedema and absent red reflex. The first suspicion must be: a. Secondary glaucoma. b. Anterior uveitis c. Bacterial endophthalmitis. d. Acute conjunctivitis Click "Show more" to see the answer and explanation. Show more Ans: c. Bacterial endophthalmitis.Explanation:Bacterial endophthalmitis is a serious infection that can occur after cataract surgery. The symptoms described are typical of this condition and require immediate treatment. Show less 36. Topical steroids are contraindicated in a case of viral corneal ulcer for fear of: a. Secondary glaucoma b. Cortical cataract. c. Corneal perforation d. Secondary viral infection. Click "Show more" to see the answer and explanation. Show more Answer: c. Corneal perforationExplanation:Topical steroids can worsen viral corneal ulcers by suppressing the immune response, leading to thinning and potential perforation of the cornea. Show less 37. The sure diagnostic sign of corneal ulcer is a. Ciliary injection b. Blepharospasm c. Miosis d. Positive fluorescein test. Click "Show more" to see the answer and explanation. Show more Answer: d. Positive fluorescein test.Explanation:A positive fluorescein test, where fluorescein dye stains the ulcerated area of the cornea, is a definitive sign of a corneal ulcer. Show less 38. The effective treatment of dendritic ulcer of the cornea is: a. Surface Anesthesia b. Local corticosteroids c. Systemic corticosteroids d. Acyclovir ointment Click "Show more" to see the answer and explanation. Show more Answer: d.

Herpes simplex keratitis is characterized by: a. Presence of pus in AC b. No tendency to recurrence c. Corneal hypoesthesia d. Tendency to perforate Click "Show more" to see the answer and explanation. Show more Answer: c. Corneal hypoesthesiaExplanation:Herpes simplex keratitis often leads to decreased corneal sensation (hypoesthesia), which is a distinguishing feature of this condition. Show less 40.

Click "Show more" to see the answer and explanation. Show more Ans: a. Neisseria gonorrhoea.Explanation:Neisseria gonorrhoeae is one of the few bacteria capable of penetrating an intact corneal epithelium, leading to severe eye infections.
