36. The Mydriasis Provocative Test is a test for which glaucoma

  1. A. POAG
  2. B. PACG✓
  3. C. NTG
  4. D. All

Mydriatic provocative test is usually not preferred nowadays because this is not physiological. In this test either a weak mydriatic or simultaneously a mydriatic and miotic (10% phenylephrine and 2% pilocarpine) are used to produce a mid-dilated pupil. A pressure rise of more than 8 mm Hg is considered positive.

37. Dark room test is a provocative test for

  1. A. POAG
  2. B. PACG✓
  3. C. NTG
  4. D. None

In Darkroom test IOP is recorded and patient is made to lie prone in a darkroom for 1 hour. Patient should must remain awake so that pupils remain dilated. After 1 hour, the IOP is again measured. An increase in IOP of more than 8 mm Hg is considered diagnostic of PACG suspect.

38. Mydriatics are contraindicated if the anterior chamber is

  1. a. Deep
  2. b. Shallow✓
  3. c. Normal
  4. d. Irregular
This is because of the risk of angle closure glaucoma.

39. Pachymetry is done in

  1. a. Glaucoma
  2. b. Fuch's distrophy
  3. c. Before LASIK
  4. d. All✓

pachymetery is the measurement of thickness of cornea Pachymetery is important in Keratoconus screening, IOP measurements, before surgeries like LASIK, Limbal Relaxing Incisions (LRI) 

40. Treatment of choice for the other eye in primary narrow angle glaucoma is

  1. A. Trabeculectomy
  2. B. Laser iridotomy✓
  3. C. Laser trabeculoplasty
