Ophthalmology Flashcards
Deep red eye that is very painful and may be associated with reduced visual acuity and blurred vision and systemic connective tissue disorders:
Scleritis
Causes of relative afferent pupillary defect:
Retinal detachment
Optic neuritis (multiple sclerosis, might present with headaches and red desaturation too)
What drops can be used to distinguish between episcleritis and scleritis
Phenylephrine
Painful red eye with photophobia and epiphora, next step:
Fluorescein staining, if epithelial defect refer urgently, managed with topical aciclovir for herpes simplex keratitis
Treatment for Herpes zoster ophthalmicus
Immediate referral/oral aciclovir
Argyll-Robertson Pupil (ARP) is Accommodation Reflex Present (ARP) but Pupillary Reflex Absent (PRA), most common cause in the UK

Elder, deterioration in vision at night, fluctuation from day to day, drusen in Bruch’s membrane:
Dry age-related macular degeneration
Bilateral recurrent uveitis with a history of pulmonary disease

Ptosis + dilated pupil = Ptosis + constricted pupil =
Third nerve palsy

Type of visual defect found in a pituitary tumour:
Bitemporal hemianopia, upper quadrant defect
Type of defect in primary closed angle glaucoma:
Unilateral peripheral visual field loss
Large irregular pupil, reacts sluggishly to light, once constricted it remains like that for a long time:
Holmes Adie pupil
Pupil doesn’t react to light, when exploring the other pupil, both dilate:
Marcus Gunn pupil
