Remember: The lamina papyracea, which forms part of the medial wall, is
paper-thin and perforated by numerous foramina for nerves and blood
vessels. Orbital cellulitis is therefore frequently secondary to ethmoidal
sinusitis.

placing a thumb firmly
against the patient’s brow
to negate the action of the
frontalis muscle, with the
eyes in downgaze. The
patient then looks up as far
as possible and the amount
of excursion is measured
with a rule. Levator
function is graded as normal
