Opthalmology Flashcards
(29 cards)
Loss of colour vision and reduced acuity?
Typically optic neuritis
Feature of proliferative diabetic retinopathy which can cause vitreous haemorrhage?
Neovascularisation
Earliest feature of diabetic retionopathy?
Microvascular aneurysms
Acetazolamide/dorzolamide mechanism? What do they do?
Carbonic anhydrase inhibitors
Lower IO pressure
Band keratopathy association?
Sarcoid
(or any hypercalcaemia)
MS vs NMO/MOG disease?
In NMO/MOG the visual loss is often severe and bilateral, with profound optic disc swelling
Connective tissue disease and a painful red eye?
Uveitis
Findings in CMV retinitis?
Necrotising vasculitis with haemorrhages
“bushfire”
Classic occular finding in acne rosacea?
Keratitis
Peripheral visual loss, night vision loss and myopia? Either fit and well or syndromic
Retinitis Pigmentosa
Arteriolar attenuation, pigmented bone spicules in the periphery and waxy optic disc pallor?
RP
What, primarily, is dysfunctional in retinitis pigmentosa?
Rods (rhodopsin protein)
Occular finding in Marfans?
Ectopia lentis (lens subluxation or dislocation)
Lisch nodules of the iris?
Neurofibromatosis
Where may the lesion be in Horner’s syndrome?
Go by the level of anhydrosis
Head, arms and trunk = central lesion
Just face = pre=ganglionic i.e. Pancoast’s or cervical rib
Absent = carotid artery
Primary angle closure glaucoma management?
1st line Prostaglandin analogues e.g. LatanoPROst
These increase uveoscleral outflow
2nd line BB or carbonic anhydrase inhibitor - these reduce aqueous production
Sudden painless loss of vision with a dense shadow starting peripherally and moving centrally?
Retinal detachment
Loss of vision and cherry red spot?
Retinal artery occlusion
Flashes and floaters?
Vitrious detachment
Visual deterioration and hazy cornea?
Acute angle closure glaucoma
Central scotoma =?
Optic neuritis
Drug causes of acute glaucoma?
TCA
Anticholinergics
Dilating drops
Superior vs inferior hemianopia?
PITS
Parietal = inferior
Temporal = superior
Drusen
Dry AMD
