On which of the following might you use different plus adds for near in
eye - unilateral Horners, unilateral Adies, Argyll-Robertson pupils,
unilateral aphakia, anisometropia, unilateral pseudophakia (other eye normal)
Corneal topography- mcqs I forget about reflective versus projected
Can saccades be measured by videophotography
Do saccades occur in 0.001secs
Protective glasses- are they made of PMMA, can laminated safety glasses
Spherical correction, when laminates shatter do they have sharp edges
Is corneal curvature in reduced eye 7.8mm
Is base curve in plus meniscus lenses on posterior surface
Does a spherocylindrical lens have one spherical and one cylindrical surface

PRK causes a photochemical reaction
Xanthophyll absorbs blue light
Usually abnormal VEP in amblyopia
Neutral density filter doesn't decrease VA in amblyopia
Some crap about lateral inhibition of ganglion cells in amblyopia

Hruby lens on table. what is this? Draw a ray diagram of it.
Line drawing of lacrimal apparatus straight from Kanski. what is this?
What is labelled A (inferior canaliculus), What is labelled E (valve
FFA. Describe the principles of this test. what does it show (it was
ink blot CSR or PED).
B scan. What is this. describe its principles. what structures are
involved. (the gain was awful-could have been a weather photo of a
snowstorm- it was probably a large retinoblastoma involving most of
cavity with calcification on its head-ie behind lens)
CT orbits. What is this. What does it show (bilateral lacrimal gland
swelling). what symptoms would the patient have?
Biometry print out- what is this (i think). which is the most accurate
reading and why (left eye as lower standard deviation), to aim for
which lens would you choose for the right eye? If the A constant was
instead of 118 how would the dioptric power of the lens change (the
was only done for an a constant of 118 so you had to understand the
rather than read it off)
Hess chart. what is this? describe its principles. what does it show?
Acute cranial nerve 6 palsy (no muscle sequelae)
Humphrey Visual fields of right and left eyes (sides were labelled).
is this? What does it show? (left superior arcuate defect with nasal
right superior hemispheric defect with some points detected around
spot) Where is the lesion?
Visual fields. At very start detected left sensory inattention (very
man) by flapping hands with patient having both eyes open looking straight
me. Then progressed to uniocular field testing with targets (I had
made from bits and bobs from staples the office superstore as I couldn't
any company that sold hat pins) it became apparent at this stage that
patient couldn't move his right arm to cover his eye (I advise all
to bring orthoptic patches to look smooth here - I didn't have them).
didn't map out much of a field defect there was certainly no sharp
cut off. my diagnosis right parietal lesion with left field defect.
questions- did i think the defect was congruous, what was the significance
it being not, what is the use of red targets.
Ocular motility. asked to do cover test. i would advise get in fast
cover test for near without glasses then straight for versions and
you don't have time for doing near then distance with glasses on then
obviously say ideally you would like to and some clinical situations
examiners may ask for it but in the vast majority getting rid of the
and just doing near accentuates the defect and gets to the point fast.
patient had right hypertropia and esophoria. didn't fit with any neurological
condition i knew (i said) and i felt must be mechanical. question-
of mechanical problem would you think it is? My answer ted. Is there
else you would like to do? T got myself a bit lost and started talking
a thyroid eye disease exam rather than mentioning how I would confirm
a mechanical versus
neurological exam (ie ductions versus versions, forced duction, slow
saccades). As I talked about TED I was asked to demonstrate lagophthalmos.
Binocular indirect ophthalmoscopy. Patient was sitting in chair. I
offered to use the
couch but was told I was fine to do it with him sitting. findings -
naevus at disc possibly
pigment stippling at macula. show how you would examine his superonasal
retina. Show how you would indent (given indenter but not actually
use it- gave a talk through). merits of 20d versus 28d lens. Who would
28d (answer paeds). Examine his other eye. No red reflex-indicates
as indirect powerful-time up
Direct-nasal chorioretinal scar. what could be the cause? its a little
for toxoplasma but that could be a cause-so any cause of
chorioretinitis?-yes-examine the anterior segment of the other eye
give you the diagnosis. It was a shell. dx trauma evisceration followed
Focimeter. bifocals. how does it work. straight forward station.
von Helmholtz keratometer. Big controversy over this station and multiple
complaints from candidates. I think it may not have been counted. External
assessor from Edinburgh had pages of candidates complaints about this.
asked about optics of the device. what would be the significance of
reading of 47.
Pupils. Bilateral Holmes-Adie though no light near dissociation detected.
your dx is bilateral Holmes-Adies is it? -yes- What else would you
do?-deep tendon reflexes, slit lamp for vermiform movements, pilo.-So
would examine for deep tendon reflexes in the clinic would
you?-yes-really?-yes. so you put pilocarpine in both eyes would you?
Slit lamp. Beam decentered, and focus out at start. Examine cornea,
retroilluminate to look for zonules (lens subluxed superiorly), what
Retinoscopy - nearly went down I think - remember that the aim is not
get the prescription right but to demonstrate the you can do retinoscopy
as you can't do a subjective with a child and the consequence could
amblyopia so take the time to not leap onto subjective fast before
that you can do an accurate retinoscopy. obviously you don't want to
yourself with only 3 minutes at the end to do all of your subjective
