OBJECTIVE To report dynamic changes in the retinal ganglion cell layer (GCL) and visual function in acute and chronic optic neuritis (ON). METHODS Sixteen eyes (15 patients) with acute ON were followed for 3.5 to 31 months (average, 10.2). The best-corrected visual acuity (BCVA) and thickness of the GCL plus the inner plexiform layer (GCL+IPL) were measured 4 to 13 times between baseline and the final visit using the ganglion cell analysis software in the Cirrus HD-OCT [high-definition optical coherence tomography] instrument. Goldmann perimetry was performed at baseline and at the final visit. RESULTS The thickness of the GCL+IPL at baseline was within normal limits in the affected (80.4 ± 4.9 microns) and unaffected fellow eyes (80.5 ± 5.0 microns). Rapid thinning to 69 ± 7.3 microns occurred during month 1 in the affected eyes, slowing during month 2, and then reaching a minimum level (63.6 ± 8.7 microns). In contrast, BCVA was lowest (mean ± standard deviation logarithm of the minimum angle of resolution, -1.29 ± 0.96) in 11 eyes at baseline, increased markedly to -0.15 ± 0.37 during month 1, and reached a maximum level (-0.18 ± 0.19) during month 2 and (-0.02 ± 0.23) at the final visit. The BCVA in the other five eyes fluctuated during month 1, increased markedly during month 2, and then reached a maximum plateau (-0.07 ± 0.20). The patterns of visual field defects at baseline were varied, and were determinants of BCVA. The visual field largely recovered in 11 eyes, but small central scotomas in four eyes and an enlarged blind spot in one eye remained at the final visit. Eyes with the least GCL+IPL thinning at month 1 or 2 had the least depression in the final deviation map. CONCLUSIONS In acute ON, the progression toward irreversible ganglion cell loss occurs rapidly during months 1 and 2. In contrast, visual function recovers rapidly during the same period. Remodeling of the neural network may occur between the photoreceptors and the reduced numbers of ganglion cells during the first months of ON. The small number of residual ganglion cells appears to compensate for the initial visual dysfunction.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D009902	Optic Neuritis	Inflammation of the optic nerve. Commonly associated conditions include autoimmune disorders such as MULTIPLE SCLEROSIS, infections, and granulomatous diseases. Clinical features include retro-orbital pain that is aggravated by eye movement, loss of color vision, and contrast sensitivity that may progress to severe visual loss, an afferent pupillary defect (Marcus-Gunn pupil), and in some instances optic disc hyperemia and swelling. Inflammation may occur in the portion of the nerve within the globe (neuropapillitis or anterior optic neuritis) or the portion behind the globe (retrobulbar neuritis or posterior optic neuritis).
