Rapidly progressive unilateral proptosis is
usual, Average age of onset is 7 years. The
tumour is derived from undifferentiated
mesenchymal cells. Various genetic
predispositions have been identified, including
variants of the RB1 gene.
3. Question

2) What is the most common site in the orbit?
3) Which type is the worse prognosis?
4) Which is the most confirmatory diagnosis?
4. Answer
1) Rhabdomyosarcoma
2) Most commonly superonasal or superior orbit
3) Alveolar
4) Incisional biopsy followed by histopathology

5. OSPE: 2
Do the Schirmer test 2 & write down your
interpretation
6. 1) Excess tears are delicately dried. If topical
anaesthesia is applied the excess should be
removed from the inferior fornix with filter
paper.
7. 2) The filter paper is folded 5 mm from one end
and inserted at the junction of the middle and
outer third of the lower lid, taking care not to
touch the cornea or lashes.
8. 3) The patient is asked to keep the eyes gently
closed.
4) After 5 minutes the filter paper is removed
and the amount of wetting from the fold
measured.
9. Interpretation: Less than 10 mm of wetting
after 5 minutes without anaesthesia or less than
6 mm with anaesthesia is considered abnormal.

10. OSPE 3
A patient came to you with corneal opacity.
What history should you take from that patient
mention with explanation for the relevant
histories?
11. Answer
• History of onset: Age of onset. If early onset
best possible treatment could not help
satisfactorily because of amblyopia
• History of trauma: If so, there may be cataract,
retain foreign body in presence trauma. And B-
Scan should be done before surgery
12. • H/O Associated pain, redness, watering,
discharge to exclude any corneal ulcer,
aphakic/pseudophakic bullous keratopathy
• H/O past surgeries
13. • H/O associated frequent change of glass
keratoconus
• H/O associated systemic problem
Hyperlipidaemia/Hypercalcemia

Q: History taking of a patient suffering from
recurrent uveitis
A: Following points to be noted during history
taking:

18. 1) PATIENT DETAILS:
1) Age: Juvenile rheumatoid arthritis (JRA) is
common in patients less than 15 years.
2) Sex: JRA is common in females, HLA – B 27
associated uveitis in males. (but during
history taking you should not asked about
gender)
19. 2) OCULAR HISTORY:
Is the disease unilateral or bilateral ?
When was the first attack?
When was the last/current attack?
What was the approximate frequency of the
attacks between the first and the last attack?
Details of prior ocular treatment.
Any previous history of rise IOP or use any
antiglaucoma agents.

related uveitis).

22. OSPE: 6
When performing cycloplegic retinoscopy on an
anxious 7-year-old boy, you notice that the
central reflex shows with movement while the
peripheral reflex shows against movement.
23. Question
1) What is the most likely physiological cause?
2) Why there are different central and peripheral
reflexes?
3) If it is physiological how will you overcome
of it?
4) What is the most likely pathological cause?
24. Answer
1) Spherical aberration
2) The periphery of the human lens is more curved
than the center, so the incoming light rays show
increased refraction compared with the light rays
that strike the central lens. In retinoscopy, this
can result in the appearance of different central
and peripheral reflexes.
25. Answer
3) Concentrate on the central light reflex when
performing retinoscopy.
4) Keratoconus

2) Give one reason in favour of your IOL choice
3) What are the options to correct astigmatism
during cataract surgery? Mention 2
28. Answer

black spot because of central scotoma, the lines help
to maintain fixation and allows the patient to outline
the limits of scotoma.
