Q

Uveitis symptoms and management

A

Anterior Uveitis:
Acutely painful red eye, decreased vision
Synechiae = iris adherence to cornea or lens (Seen on slit lamp examination)
Flare = leukocyte accumulation, HYPOPON may form (pus seen as white fluid level)
PHOTOPHOBIA
CONSTRICTED OR NON-REACTIVE DILATED PUPIL
TEARING
OPTIC DISC swelling and macular oedema may occur

Differentials = acute angle closure glaucoma(patients typically older than 40!!, patients may see Halos around lights, eye will be DILATED)

Associated w autoimmune systemic diseases

Posterior Uveitis:
Painless, floaters/flashers, lacrimation, decreased visual acuity

Steroid and Cycloplegic(a.g atropine) eye drops

+ management of underlying disease
Infectious causes = urgent specialty consultation

Q

What are the differenr stages of diabetic retinopathy and how are they managed?

A

Background retinopathy

  • hard exudates, microaneurysms, blot haemorrhages
  • glyceamic control

Pre-prolifereative

  • cotton wool spots/soft exudates
  • pan retinal photocoagulation

Proliferative

  • visible new vessels
  • pan retinal photocoagulation

Pre-proliferative with macular oedema
- anti VEGF injection = aflibercept, ranibizumab, bevacizumab
