Nuremberg, Bavaria; died 13th May, 1885, Göttingen

27. Henle's fibers
1.Outer plexiform layer makes synapses with dendrites of bipolar
cells In the macular region, this is known as the Fiber layer of Henle

28. Hassle-Henle bodies
Small hyaline excrescences in the periphery of the Descemet
membrane.

29. Crypts of Henle
.microscopic pockets found in the conjunctiva They are responsible for
secreting mucin

30. Elschnig

(August 22, 1863 – 1939) was an ophthalmologist born in Leibnitz, Austria.

with advanced hypertensive retinopathy

form of Coat's disease.

50. von Graefe

51. Friedrich Wilhelm Ernst Albrecht
von Graefe
German ophthalmologist, born 22nd May, 1828, Finkenheerd (Mark

down.

53. Graefe's knife
knife designed for cataract extraction. Now of historical interest.

American ophthalmologist, born 1908, Fall River, Massachusets; died 9th
September, 1993, Bethesda.

56. Cogan’s Dystrophy
epithelial basement membrane dystrophy

57. Cogan's sign
Cogan's lid twitch, in patients with myasthenia. When the patient's
eyes are directed downward for 10 to 20 seconds and the patient is
then instructed to make a vertical saccade back to primary position,
the upper eyelid elevates and either slowly begins to droop or else
twitches several times before settling into a stable position

58. Cogan-Reese disease
characterized by a matted or smudged appearance to the
surface of the iris, unilateral glaucoma in the eyes with multiple
peripheral anterior synechiae, multiple nodules of the iris

59. Cogan's syndrome
Syndrome of interstitial keratitis characterized by abrupt onset of
vertigo, tinnitus, and usually rapid development of bilateral deafness

60. Cogan’s rule
Testing for optokinetic nystagmus. Finding asymmetrical OKN ...the
lesion is more likely to reside in the parietal lobe, and more likely to be
nonvascular, that is a tumor (Cogan's rule(

Scottish ophthalmologist, born 1850, Dunnet – died on 29 November
1909, Hindhead

63. Marcus Gunn jaw-winking
phenomenon
unilateral eyelid movement with movement of the jaw

64. Marcus Gunn pupil
relative afferent pupillary defect caused by optic nerve lesion or
extensive retinal disease.

65. Gunn's dots
light reflectios from internal limiting membrane around
disc and macula

66. Gunn’s Sign
AV, or arteriovenous nicking is the phenomenon where a small
artery (arteriole) is seen crossing a small vein (venule), which results
in the compression of the vein with bulging on either side of the
crossing. This is most commonly seen in eye disease caused by
high blood pressure
