3. In a patient with uveitis it is important
to ensure that there is no potentially
life-threatening systemic disease present
or an infectious cause for the
inflammation
4. Urgent specialist
cardiovascular
evaluation is needed
in a patient with a
retinal artery
occlusion in order
to reduce the risk
of a stroke or a
similar event
occurring in the
fellow eye
5. Avoid the use of carbonic anhydrase
inhibitors in patients with sickel cell
anaemia as these drugs can cause sickling
and vascular occlusion
6. In a patient with painless visual loss
after severe body trauma, examine the
posterior pole of both eyes for signs of
Purtscher retinopathy.
7. All forms of corticosteroid treatment
should be discontinued if possible in
patients with chronic or recurrent central
serous chorioretinopathy.
8. Patients with oculocutaneous albinism are
at increased risk of cutaneous basal cell
and squamous cell carcinoma and should
take precautions to avoid exposure to
sunlight
9. Immediate systemic steroid treatment
should be prescribed for a patient with
ischaemic optic neuropathy secondary to
temporal arteritis, to reduce the risk of
visual loss in the fellow eye
10. Urgent CT angiography is needed in a
patient who presents with an acute third
nerve palsy that involves the pupil, to
exclude an expanding intracranial
aneurysm.
11. Hearing and corneal sensation should be tested
in patients with a sixth nerve palsy, to exclude
a vestibular schwannoma (acoustic neuroma).
15. All patients with papilloedema should
undergo urgent neuroradiological
investigation to exclude intracranial
pathology.
16. Neurological lesions causing optic nerve or chiasmal
compression can produce visual field defects that may be
misinterpreted as glaucomatous, and neuroimaging should
be performed if there is any suspicion; some practitioners
routinely perform a cranial MRI in all cases of NTG.
