Opthalmology Flashcards
Painless loss of vision differentials
Retinal detachment Central retinal artery occlusion Central retinal vein occlusion Ischaemic optic neuropathy Vitreous haemorrhage Optic neuritis CVA
Differentials for gradual loss of vision
Cataracts Glaucoma Macular Degeneration Retinitis pigmentosa Optic neuritis
Painful red eye
Conjunctivitis - bacterial/viral/allergic
Acute angle-closure glaucoma
Infectious keratitis
Uveitis
Episcleritis
Scleritis
Subconjunctival haemorrhage - may be painless
Glaucoma vs uveitis
glaucoma - semi dilated pupil, hazy cornea
Uveitis - small fixed oval pupil, ciliary flush
Rheumatoid arthritis eye problems
Keratoconjunctivitis sicca (most common) Episcleritis Scleritis Corneal ulceration Keratitis
