[Clinical study of optic neuritis combined with viral hepatitis]

To investigate the clinical manifestation, management and prognosis of optic neuritis combined with viral hepatitis.

Retrospective study case series. Clinical data from twenty patients with optic neuritis combined with hepatitis who were hospitalized in Beijing Tongren Hospital neural eye ward from September 2003 to June 2010 were collected, the clinical characteristics and visual field changes in the group of patients were summarized, and comparison between the vision before and after treatment was made by the Wingerchuk vision classification.

Among the twenty patients, eighteen patients had chronic hepatitis B and two patients had chronic hepatitis C. Thirteen (65%) patient were monocular, sixteen (80%) patients were single-phase course. Twenty-seven eyes were affected. Disc edema was very common which was found in 14 eyes (52%), severe vision impairment (Best corrected visual acuity worse than 20/200) were recorded in 19 eyes (70%). Lower altitudinal visual field impairment was more common which was found in 10 eyes (50%). All patients were followed for 3 months after steroid therapy, complete visual recovery or significant improvement was seen in only 3 eyes (11%) or 4 eyes (15%). Minor improvement was seen in 12 eyes (44%), while 8 eyes (30%) had no improvement.

In this study, optic neuritis combined with hepatitis usually showed severe visual impairment. Although the vision of some patients could completely recover after steroid therapy, most of the patients had poor recovery. Combination of steroid and anti-viral therapy should be considered in the management of optic neuritis combined with hepatitis.
