“…In total, 50% of the eyes with accurate VF findings had some degree of VL at presentation; however, only 21.2% did not have normal VF after treatment. Hung et al (25) followed 10 patients with IIH and found visual function improvement in all but two eyes during follow-up. At the last visit, 40% of eyes had normal VF; however, it was mild or minimal in 40% and severe in two patients (25) .…”

Purpose: To investigate the frequency of visual loss (VL), possible predictive factors of VL, and improvement in patients with pseudotumor cerebri (PTC) syn drome. Methods: We reviewed 50 PTC patients (43 females, seven males) who underwent neuro-ophthalmic examination at the time of diagnosis and after treatment. Demographic data, body mass index (BMI), time from symptom onset to diagnosis (TD), maximum intracranial pressure (MIP), occurrence of cerebral venous thrombosis (CVT), and treatment modalities were reviewed. VL was graded as mild, moderate, or severe on the basis of visual acuity and fields. Predictive factors for VL and improvement were assessed by regression analysis. Results: The mean ± SD age, BMI, and MIP were 35.2 ± 12.7 years, 32.0 ± 7.5 kg/cm², and 41.9 ± 14.5 cmH 2 O, respectively. Visual symptoms and CVT were present in 46 and eight patients, respectively. TD (in months) was <1 in 21, 1-6 in 15, and >6 in 14 patients. Patients received medical treatment with (n=20) or without (n=30) surgery. At presentation, VL was mild in 16, moderate in 12, and severe in 22 patients. Twenty-eight patients improved and five worsened. MIP, TD, and hypertension showed a significant correlation with severe VL. The best predictive factor for severe VL was TD >6 months (p=0.04; odds ratio, 5.18). TD between 1 and 6 months was the only factor significantly associated with visual improvement (p=0.042). Conclusions: VL is common in PTC, and when severe, it is associated with a delay in diagnosis. It is frequently permanent; however, improvement may occur, particularly when diagnosed within 6 months of symptom onset.

“…3,4 The incidence of IIH tends to be quite low in Asians. 7,8 Only two cases (one man and one woman) with IIH were reported in Hokkaido, Japan, during a 1-year study in 1993. 7 Fourteen patients were diagnosed with IIH between January 1999 and June 2006 in Korea.…”
