OK BlackNDecker will post my qns in a single thread....
Thanks Rendar5 for ur input..... Heres what i learnt...
.Adie's Pupil
Dilated pupil which may react better to near than to light. It is probably due to disease
affecting the ciliary ganglion. Is hyper-sensitive to any weak Pilocarpine (eg. 0.1%) with
constriction of the pupil, in contrast to the pharmacologically dilated pupil (eg. by atropine)
which will not constrict.
There may be an associated loss of tendon reflexes, particularly the ankle jerks, but there is
almost never any associated systemic disease. Over a period of years, the condition is likely
to become bilateral and the initially dilated pupil will gradually reduce in size. However, its
poor reaction to light will continue.
2.- Marcus Gunn Pupil-paradoxical dilatation of pupils in swinging flash-light test,seen in retinal detachment,optic neuritis etc.
3.Pupils in pontine lesions-; pontine lesions cause miosis but normal light response. pin-point pupils following pontine haemorrhage;
4.central diencephalic herniation causes fixed dilated pupils:
5.Argyll Robertson Pupil- Accomodation Reflex Present(ARP-mnemonic).
6.Pupil in Uncal herniation- findings include ipsilateral pupillary dilation, loss of light reflex, and ptosis due to compression of cranial nerve III.
