Ophthalmology + ENT Flashcards
Uveitis symptoms and management
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
What are the differenr stages of diabetic retinopathy and how are they managed?
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
Optic neuritis
Symptoms
Investigations
Management
subacute or acute onset of pain in the eye worse with eye movements
Reduced colour vision
RAPD
Vision loss- central scotoma - described as seeing through cloud/fog
MS = RF
MRI optic nerve
Methylprednisolone and prednisolone
scleritis symptoms
Dark red eyes
Severe eye pain especially with eye movement
50% associated with systemic disease especially RA
Episcleritis is similar. It can cause irritation but importantly NO PAIN
Visual field defects
Go through diagram
Obstructive sleep apnea
Symptoms
Investigations
Management
Chronic snoring, excessive daytime sleepiness, insomnia
1st line = polysomnography = AHI ≥15 episodes/hour or AHI ≥5 with symptoms or comorbidities
CPAP
Upper airway surgery if discrete anatomical lesions present
BPPV
Symptoms
Investigation
Management
Vertigo from bppv - <30s
Nausea, imbalance, lightheadedness - may persist longer
Absence of neurological or otological symptoms
Suggestive history + a positive Dix-Hallpike manoeuvre(unilateral delayed onset torsional nystagmus) or a positive supine lateral head turn
Repositioning maneuvers - Epley manoeuvre is best
Tonsillitis
Symptoms
Management
Fever >38
Pain on swallowing
Tonsillar exudate (in bacterial causes)
Sore throat, cough, swelling of neck glands may occur
Usually viral and resolve on own
Antibiotics
Rhinosinusitis
Symptoms
Management
Purulent nasal discharge
+ nasal obstruction or facial pain/pressure/fullness
<10 days = viral cause
< 4 weeks = bacterial cause or if they worsen after initial improvement
Antibiotics if bacterial
Differentials - Allergic and non allergic rhinitis
Menieres disease
Symptoms
Investigation
sudden onset of vertigo, hearing loss(low frequencies), tinnitus, and sensation of fullness
Audiological tests
Scleritis symptoms
Painful eye movement Eye pain which is boring and aching Deep pink colour to the eye Visual acuity preserved to late Associated with rhuematoid arthritis and other systemic symptoms
