25
optic tract meet maternal geniculate uncles. one goes through temporal and one through parietal lobe. temporal lobe is inferior to parietal lobe it takes things form the superior optic radiation and the partial lobe gets it from the inferior optic radiation
visual field defects
26
pituitary tumour classically cause what visual field defect
bitemporal hemianopia
27
60yr old patient with diabetes preens with gradual deterioration of vision and dazzling of view in well lit places
cataracts
28
cataracts is lens opacity, risk facts are age and diabetes and stereo smoking and alto sue and genetics diagnosis's via slit lamp treatment via phaecoemulfificaiton and lens implant symtposm
bilateral painless blurring of vision over years, glare whilst driving at night cataracts does not require urgent surgery

scleritis is inflammation of the sclera and RF include ocdntions such as RA, GP And polyarteritis ndoosa symptoms are diagnosis are ophthalmology examination and rheumatology review - could be flare
red eye, deep boring pain on the eyes, pain on movement , photophobia and decreased acuity Treatment with high dose seteriods and DMARDS
31
sudden loss of vision in right eye. hypertension , hyperlipidemain and diabetes and carotid bruit on examination
central retinal artery occlusions pale retina with cherry red spot - stroke int eh artery
32
central retinal artery occlusion is stroke of central retinal artery RF including CVD and stroke and carotid disease symptoms are
sudden painless monocular severe visual loss and pale retina dn cherry red spot. treatment is excluded giant cell arteritis ( temporal arteritis - check CRP or ESR) , stroke work up and according to local protocols easily treateded with steroids
33
which is typical appearance of a retina with CRAO
pale retina with cherry red spot
34
CMV retinitis

central retinal vein occlusion
stormy sunset appearance exactly same symptoms as arteries
37
60 yr old man if refereed to you by opticiity after fundoscopy shown eye with big bright spot
(chronic) glaucoma
38
chronic glaucoma is progressive characteristic of optic nerve damage and visual field losss. RF is age , raised intracoular pressure , black African and high myopia symtposm are diagnose is slit lamp exam ( CDR>1/3, gonioscopy , perimetry and tonometry treatment is
none until late acute scotoma peripheral VL spot needs to be bigger than 1/3 topical latanoprost and trabeculoplasty, trabeculectomy advanced cases tunnel vision only can see through there macula
39
myopia is a risk factor for chronic glaucoma
yes but not for acute angle closure glaucoma
40
10 yr old male with right eye difficult to open after sleep, diffuse conjunctival injection and significant mucopuruletn discharge
bacterial conjunctivitis red/pink eye and itchy if allergic , one purulent if bacterial treatment for bacterial is chloramphenicol if docent resolve allergic avoid allergen and antihistamines viral self resolves
41
what is visual acuity
Visual acuity (VA) is a measure of the ability of the eye to distinguish shapes and the details of objects at a given distance.
42
on routine review of diabetic man has this eye cataract diabetic retinopathy age related macular degneraton or glaucoma
diabetic retinopathy
43
diabetic retinopathy one of the microvasuclar complications- include chronic hyperglycaemia causing cap damage RF are DM fro over 20 years clinicla features include painless bilateral VL exudates and haemorrhage treatment is
strict glycemic control panretinal photocoagulation PRP intravitreal anti-VEGF
44

retinopathy nephrotpathy neuropahty
45
previously healthy 63yr old man left eye pieced by intermitted flashes and curtain like loss of lateral vision that began when he woke up
retinal detachment
46
retinal detahcenet is neural retina separation from RPE , high myopia, trauma and age and strong sneeze are RF - clinical features treatment
flashes and floaters curtain coming down diagnosed on fundoscopy time critical surgery - gas tamponade
