VF defects revealed central scotoma in 26 eyes (53.1%), paracentral scotoma in 12 eyes (24.5%), cecocentral defects in 6 eyes (12.2%), blind spot enlargement in 3 eyes (6.1%), and quadrantanopia in 2 eyes (4.1%) within 1 week after onset.
Patients often exhibit relative afferent pupillary defect, dyschromatopsia, and central, cecocentral, or arcuate visual field defects.
(15) Visual field defects are common and show a central or cecocentral scotoma.
Localized cecocentral scotomas typical of optic neuropathy due to tobacco amblyopia were detected in all the subjects whereas their central vision was preserved.
The most common defects seen in IIH are blind spot enlargement, generalized constriction, and loss of the nasal visual fields, especially inferonasal (6) Other common field defects described include inferior altitudinal loss, superonasal and superotemporal, loss, arcuate defects, and scotomas (central, cecocentral, and paracentral.
Visual field defects in optic neuritis at presentation included diffuse visual field loss (48%), altitudinal defects (15%), central or cecocentral scotoma (8.3%), arcuate or double arcuate (4.5%), hemianopic defects (4.2%), and others.
The neuropathy has included an optic form--characterized by subacute (i.e., 3-30 days) onset, decreased visual acuity, decreased color vision, and/or central or cecocentral scotomata--and a peripheral form; both forms have been characterized by weight loss and easy fatigability.
(*) For the optic form, major criteria were 1) decreased visual acuity (below 20/25), 2) decreased color vision (failure to identify two or more of the first eight Ishihara plates), 3) bilateral central or cecocentral scotomata, 4) decreased contrast sensitivity, and 5) bilateral loss of optic nerve fibers in the papillo-macular bundle; minor criteria were 1) temporal pallor of optic disk (1 month after symptom onset), 2) photophobia or ocular burning sensation, and 3) loss of horizontal smooth pursuit.
Of 136 eyes from 68 patients that underwent visual field examination, central scotoma accounted for 69.9%, cecocentral scotoma connected with blind spot for 8.0%, paracentral and temporal defect for 6.6%, and diffuse defect for 15.5%.
In addition, if patients had abnormal color vision, any neurological symptoms, a history of acute visual disturbance, nonglaucomatous visual field defect (e.g., visual field defect respecting the vertical meridian, central, or cecocentral visual field defect), and the presence of optic disc pallor, they were excluded from this study.
