26 3-66a3-66a - Shunt Vessels (Post-papilledema)The retino-choroidal collaterals seen with chronic papilledema begin with a "Hairnet" of telangiectasias that gradually winnow down to one or more large collateral tortuous draining channel. The presence of these vessels is evidence of long standing disc swelling. When the CSF pressure is lowered, t...Shunt Vessels (Post-papilledema)

28 4-354-35 - Cupped Optic NerveAtrophic Glaucoma Atrophic glaucomatous discs show thinning of the neuro-retinal rim, "saucerization" (which is shallow cupping), evidence of peripapillary atrophy, and pallor of the very narrow neuroretinal rim. Notice that there is severe atrophy of the nerve fiber layer.Cupped Optic Nerve

33 Figure-15Aberrant Regeneration of the Right PupilAberrant regeneration of the right pupil in a man with a large intracavernous sinus meningioma causing a pupil-involving, incomplete third cranial nerve palsy. His pupil is round when he gazes straight ahead (top). When he tries to rotate the eye medially, the pupil constricts, but a segment of the ...Pupil Disorders; Aberrant Regeneration; Third Nerve Palsy
34 Figure-12An Enhancing Bladder Metastasis Involving the Tectum of the MidbrainMagnetic resonance image of an enhancing bladder metastasis involving the tectum of the midbrain of a 56-year-old man who developed double vision resulting from skew deviation and divergence insufficiency.

37 Figure-14Argyll Robertson PupilsArgyll Robertson pupils in an elderly man treated for tabes dorsalis in 1952. His pupils are small and slightly irregular, constrict poorly in response to light stimulation (top), dilate poorly in darkness (middle), but constrict promptly in response to near stimulation (bottom).Argyll-Robertson Pupil; Diagnosis, Pupil Disorders; Etiology, Pupil Disorders; History, Pupil Disorders; Pathology, Pupil Disorders
38 Figure-10Assessment of an Afferent Pupillary Defect When Only One Iris is FunctionalAssessment of an afferent pupillary defect when only one iris is functional. In this example, a right-sided parasellar tumor is compressing both the optic and oculomotor nerves, causing an optic neuropathy and a pupil-involving third crainial nerve palsy. The pupil on the affected side has both an a...Pupil Disorders; RAPD; Afferent Pupillary Defect
39 coloboma.jpgBilateral Iris ColobomasColoboma literally means a "gap"-and can be used to describe any fissure, hole, or gap in the eye. The term most often is used to refer to a congenital gap in the disc, retina, the choroid, and the iris. Colobomas occur because the embryonic fissure fails to fuse. Since the fissure closure begins in...Congenital Pupillary Abnormalities; Pupil; Etiology, Pupil Disorders; Pathology, Pupil Disorders; Correctopia

41 Figure-23Enhanced Mydriasis in Response to HydroxyamphetamineEnhanced mydriasis in response to hydroxyamphetamine in a 77-year-old woman with a long-standing, preganglionic, right-sided Horner's syndrome that occurred following cervical neck dissection for thoracic outlet syndrome 30 years earlier. Miosis of the right pupil is apparent in room light (top).

44 Figure-11Hand-held Equipment Used to Measure a Relative Afferent Pupillary DefectHand-held equipment used to measure a relative afferent pupillary defect and to record pupil sizes. Four neutral density filters (0.3, 0.6, 0.9, 1.2 log units) are conveniently carried in a soft cloth carrying pouch. A bright light source (a Finhoff model illuminator is shown here) is ideal for stim...RAPD; Relative Afferent Pupillary Defect; Pupil; Reflex, Pupillary; Pupil Disorders; Afferent Pupillary Defect
45 Figure-21Left-sided Dilation Lag in a Man with Horner's SyndromeLeft-sided dilation lag in a 29-year-old man with Horner's syndrome caused by a posterior mediastinal ganglioneuroma. Note that the degree of anisocoria is greater after 5 seconds in darkness (top) compared with findings after 15 seconds in darkness (bottom).Diagnosis, Horner Syndrome; Physiopathology, Horner Syndrome; Reflex, Pupillary; Dilation Lag; Horner's Syndrome

49 Figure-03Location of Pupillomotor FibersLocation of pupillomotor fibers are depicted as dark regions on cross-sections of the right (R) and left (L) oculomotor nerve at various locations along its course, including its emergence from the brain stem in the interpeduncular fossa (1), the midsubarachnoid segment (2), the level of the dorsum ...Autonomic Anatomy; Pupillomotor Fibers
50 glaucoma notchingNotching of the Neuro-retinal RimThe neuro-retinal rim becomes thinner; in particular the rim superotemporally and inferortemporally may develop a notch which is usually superior or inferior and rarely nasal or temporal. These notches are believed to be due to focal ischemic damage to the neuro-retinal rim. Glaucoma with Notching a...Glaucoma
