MCQs
MCQs:
More squint stuff than expected (particularly
gadgets such as Bagolini glasses etc). Went
pretty well and reading Elkington x (almost) 2,
doing a few chapters from Bahn and reading the
squint chapter from Kanski more than enough.
OSE:
Entirely predictable. Know the principles, pass
the exam. Oculus course very helpful hear –
really don’t need to know much detail about
tests.
-
Humphrey visual field = homonymous
hemianopia with predictable questions about
reliability indices etc
-
CT orbits = calcified lesion; didn’y know
what it was, but then again wasn’t asked.
Questions re test and possibility clinical
signs from lesion
-
Hess = Brown’s; principles etc. Not actually
asked for diagnosis.
-
Ray diagram = slit lamp (i.e. compound
microscope) – had to make he light bend a
bit for the diagram to work!
-
IOL calculation = which formula to use, etc.
I didn’t notice that the eye had short axial
length, so should have mentioned that I
guess (i.e. SRK-T etc)
-
Ultrasound = RD (I think – can’t remember!).
Principles….yada yada yada
-
Induced prismatic effect from decentration
-
FFA; wasn’t entirely sure about diagnosis,
but again they didn’t ask!
OSCE:
I had been on the Opticus course in Bradford, so
this felt familiar to me despite it being my 1st
attempt at the exam.
-
Visual fields station was a bit odd – found
a small, nasal scotoma but didn’t map it
very well.
-
Slit lamp OK – patient had PI and shallow AC
(only had to describe techniques – Friday’s
tutorial a great help here!)
-
Keratometer – took a while to switch the
thing on. Found a horizontal reading OK, but
struggled a little with the vertical
meridian (image seemed to be very inferior
on the cornea and not possible to centre) –
I got a reading in the end ~ the first, but
apparently lots of people couldn’t get a
second at all, which led to the diagnosis of
keratoconus being revealed! Questions about
principles of keratometer and other ways to
assess corneal curvature (topography etc)
-
Focimeter - wobbly machine so I had to hold
the specs against the lens rest. Bifocals –
seemed straight forward (-1.25 + 2.00 x 175
with a +3.00 add), but the chap then asked
‘how did you find the axis’, which got me
worried and, after theoretical bit, gave me
a simple +2.00 spherical lens to do.…
-
Direct – was quite straightforward. One
cupped disc – asked differential… ‘is macula
normal?’
-
Indirect – struggled as I expected, but
found treated lesion ?MM. Predictable
questions, but wasn’t sure if I looked slick
enough.
-
Pupils – R RAPD. Had to do reverse as looked
like trauma to R eye. The examiner was
asking if I could like the patient having ‘2
pupils’ and RAPD – I couldn’t think of
anything else, but is there a syndrome he
was getting at? Random question re Horner’s
and pharmacological tests, which was fine
and entirely predictable.
-
Motility – teenage girl with accommodative
eso. A little frustrating because she
clearly had a L/R that they weren’t
interested in! Seemed to go OK, though
Refraction:
Couldn’t have gone better. 50 yo chap; 6/36 BE
to 6/5 after ret (very clear reflex and decent
size pupils). Leisurely subjective and did
Maddox Rod before reading add. Finished after 20
minutes. I had practised for this a lot (lucky
to work in a department with friendly optoms
with plenty of time to teach and all cataract
patients refracted at 4 weeks); I think you need
to be able to do a pretty tricky patient
comfortably in 28ish minutes, so there is margin
for error. I was lucky to get a really good
patient, but as lots of people had said that the
refraction is the ‘killer’ I put much more time
in here than on the OSCE and made sure I
understood what I was doing (not as simple as
doing n refractions). Get the ret accurate and
then subjective etc is easy – no skill to that
bit, just need to look slick.
