Elschnig's spots: seen in Hypertensive choriodopathy
Elschnig's pearls(Elschnig's bodies): a type of after cataract
Elschnig's scleral ring : Scleral ring is a white circular band that separates the
intrapapillary region of optic disc from the peripapillary area.The scleral ring itself does
not belong to optic disc.This is important for all optic disc measurements because the
inclusion of scleral ring as part of optic disc falsely enlarges the neuroretinal rim & decreases cup/disc ratio.Loss of nerve fiber layer in Glaucoma can make the scleral ring
more visible due to loss of overlying tissue.
Elschnig's conjunctivitis: Chronic conjunctivitis associated with hyperplasia of the tarsal
gland and the frothy secretions
Z-plasty (Elschnig's operation): is useful to correct mild to moderate degree of cicatricial
Ectropion.
Elschnig's syndrome(Elschnig’s complex): Also known as Blepharo-cheilo-dentin (BCD)
syndrome. Features include ectropion of lower eyelids, distichiasis of upper eyelids,
euryblepharon(symmetrical enlargement of the palpebral aperture associated with large
eyelids), bilaterally cleft lip/palate, oligodontia, and conical crown form. Initially known
under the eponym Elschnig syndrome.
Elschnig's theory: Elschnig suggested the anaphylactic theory of the pathogenesis of
sympathetic ophthalmia. According to this theory, it is not a question of a particular
infection, but of an anaphylactoid inflammation against the body’s own uvea tissue.
Under certain conditions, uvea tissue damaged by trauma will act as an antigen and
subsequently occasion a sensibilisation of the body’s own uvea albumin. This causes an
anaphylactic uveitis on the undamaged eye.
Elschnig's intracapsular forceps: fine untoothed forceps for holding tissue, swabs,
sutures, etc; removing things like clots, capsule fragments, lens, etc; used in cataract
surgery.

  • 1st Purkinje image is the reflection from the anterior surface of the cornea.
