check if opthalmoscope is in good working condition
inform examiner that u would tell the pt that u r going to flash bright light in his eyes to have a look at the back of his eyes and during examination u will come very near to his face
ask him to fix his gaze at a distant object
DIM LIGHTs
examination of rt eye e ophthalmoscope held in rt hand and look through e ur rt eye vice versa is for lt eye
--hold instrument to eye e index finger on thelens dial
--approach from shallow angel (15--20 degree)
approach on the same level as equator
--note and comment on red reflex
--note and comment on anterior surface of eye
--come near and focus on retina
--identify optic disc and comment on colour ,cup,size and margins
--follow blood vessels in 4 quadrants
--seek to identify the macula and fovea
--some times 2 eyes of dummy will have 2 different pathologies
--report ur findings to the examiner

common slides kept r
hypertensive retinopathy
-diabetic retinopathy
3--pappiloedema
--normal

diabetic retino pathy(lazer)
extensive pan retinal photocoagulation for previous proliferative retinopathy
macula looks healthy, visual acuity at this stage is 6/9 and would be maintained at this level

sajida · Sunday 1st of August 2004 10:32:59 PM (6 years ago) #3

diabetic retinopathy(maculopathy)

rt fundas of young type 1 diabetic showing hard exudate close to macula.visual acuity is 6/5,this is an early case of diabetic maculopathy and may require laser treatment

sajida · Sunday 1st of August 2004 10:36:34 PM (6 years ago) #4

diabetic retinopathy(background_)
fundas photograph rt eye, dot and blot haemorrhagess mainly temporal to the macula and a nerve fiber haemorrhage in the upper part of fundas,there is a cresent temporal to the optic disc which is e in normal limits

sajida · Sunday 1st of August 2004 10:39:55 PM (6 years ago) #5

diabetic retinopathy(proliferative)
fine new vessels on the optic disc,dot/blot haemorrhages elsewhere, rainbow type leison in the lower part of the pic is an artefact,pt require panretinal photocoagulation to preserve vision

sajida · Sunday 1st of August 2004 10:43:34 PM (6 years ago) #6

diabetic retinopathy(maculopathy and cotton wool spot)
area of hard exudate adjacent to lt macula(circinate) e central dot haemorrhages,cotton wool spot(retinal ischemia) inferior to optic disc,visual acuity 6/6, for focal laser

sajida · Monday 2nd of August 2004 02:11:05 AM (6 years ago) #7

diabetoic retinopathy(maculopathy)
exudation temporal to macula and close to the fixation marker in the lt eye ,there r dot and blot haemorrhages temporal to macula ,this is classified as diabetic maculopathy

sajida · Monday 2nd of August 2004 02:14:02 AM (6 years ago) #8

diabetic retinopathy(microaneurysm)
there r some red dots in the fundas which represent microaneurysm and small dot haemorrhages, the optic disc is normal and the optic disc vessel on it r also e in normal limits

NORMAL

sajida · Monday 2nd of August 2004 02:19:23 AM (6 years ago) **#10**

extensive scarring(glial tissue formation) e traction lines,old laserburns,fovea is healthy,visual acuity is 6/9

sajida · Monday 2nd of August 2004 02:23:17 AM (6 years ago) **#11**

there r nerve fiber haemorrhages,which look feather shaped,also some dot and blot haemorrhages and a cotton wool spot associated e retinal haemorrhage adjacent to optic disc,some of retinal vessels r rather tortous and dilated ,vision is unaffected at this stage

SOME MORE SLIDES

this is a microangiopathy chacterized by microaneurysm, dot and blot haemorrhages causing occlusion and leakage resulting in retinal ischemia

sajida · Friday 6th of August 2004 04:36:44 PM (6 years ago) **#17**

retinal vein occlusion
retinal ischemia leading to neovascularisation which increases the risk of intraoccular haemorrhage

sajida · Friday 6th of August 2004 05:36:05 PM (6 years ago) **#18**

this is a central retinal vein occlusion,the central vein became blocked and hydrostatic pressure developed which resulted in multiple ruptures e i n the capillary bed of the retina giving the appearance of 360 degree of retinal haemorrhage

Image showing the funduscopic findings in miliary tuberculosis - note the pale lesions (marked by arrow) representing tuberculous infiltrates of the choroid. Miliary tuberculosis is a complication of primary infection with Mycobacterium tuberculosis. Miliary TB most frequently affects the lungs (90%), meninges (tuberculous meningitis 25%), liver/spleen, kidneys, adrenal glands and the choroid
