Q

Painful red eye with a mucopurulent discharge. There is circumcorneal redness, with a hypopyon and a white opacity of the cornea

A

Keratitis

22
Q

When is a hypopyon seen?

A

When pus cells accumulate in the anterior chamber of the eyes

23
Q

Unilateral red eye pain, photophobia and mild reduction in visual acuity, and a small pupil?

A

Iritis

-the pupil is smaller than the unaffected side

24
Q

Where are keratic precipitates seen?

A

These are aggregates of cells on the posterior surface of the cornea

25
Q

Severely painful red eye in an elderly man with reduced visual acuity, nausea and vomiting. The pupil is fixed and semi-dilated. There is intense engorgement of the corneal and episcleral vessels with corneal oedema.

A

Acute glaucoma

26
Q

Which condition is most commonly seen in older patients with long-sightedness?

A

Glaucoma

27
Q

Photophobia and acute painful erythema limited to the inferolateral quadrant of the eye in a 35 year old woman

A

Scleritis

  • usually self-limiting over 7-10 days
  • can prescribe artificial tear or even mild topical steroids if the discomfort is severe
  • episcleritis can also be limited to a particular area of the sclera but it is characteristically less painful and more of an irritation
28
Q

Holmes-Adie pupil

A

Characterised by a dilated pupil, which shows a delayed and incomplete constriction to light
If this occurs in association with reduced deep tendon reflexes, it is called Holmes-Adie syndrome

29
Q

A 35 year old female patient presented with photophobia and an enlarged left pupil, which showed a delayed and incomplete constriction to light. Accomodation was relatively normal. A pilocarpine test was positive and no other neurological abnormality was found?

A

Holmes-Adie syndrome

30
Q

Treatment for anterior uveitis?

A

Topical steroids and mydriatics

e.g. pred. forte and cyclopentolate

31
Q

Treatment for meibomian cyst?

chalazion

A

Apply heat and massage daily

  • self limiting
  • no role for topical antibiotics
32
Q

In predisposed individuals, certain drugs can induce angle closure. Name some examples

A

Nebulised ipratropium and TCA

because of their anti-muscarinic effects

33
Q

Short-acting mydriatic

A

Tropicamide (most commonly used)

34
Q

What is phenylephrine?

A

Intermediate acting mydriatic

35
Q

Long acting mydriatic

A

Cyclopentolate and atropine

36
Q

In which condition would adrenaline dilate the pupil?

A

Horner’s syndrome (pupil is sensitised to effects of adrenalina)

37
Q

Hypromellose

A

Artificial tears

-you could use these in Sjogrens

38
Q

Initial treatment for chronic glaucoma?

A

Topical beta blocker (e.g. timolol)
-if this doesn’t work, you can try parasympathomimetics (e.g.pillocarpine), carbonic anhydrase inhibitors (e.g. dorzolamide) and prostaglandin analogues (e.g. latanoprost). If medical treatment fails –> trabeculectomy

39
Q

Complete third nerve palsy and dilatation of the pupil?

A

Yes

50
Q

A 34 year old man presents to his GP complaining of pain in both eyes, which is worse when he presses on them through closed eyelids.
