The diameters of the optic nerves in 54 patients with high intracranial pressure(ICP)were checked and measured with B type ultrasonic tomography and the relationship between thewidth of optic nerve and the optic papiliedema was studied. The results showed that the average diameter (6. 324-0.53)mm of the optic nerves in patients with high ICP was wider than that(3.61 ~:0.29 )mm in health subjects (P(0.01). The rate of increasing width of optic nerve (87.00%)was higher than that (67.00~)of papilledema (P(0.05). In addition,in 19 patients with ICP between 1.97 and 2.50 kPa, the rate of increasing width of optic nerve (79. 00~)was higher than that (42.00%)of papilledema (P (0. 05). These results indicated that measuring the diameter of optic nerve might be more practical than observing tile presence of papilledema in diagnosing high ICP,especially in early stage. （Chin J Ocul Fundus Dis,1996,12: 86-87）
OBJCTIVE :To investigate the fundus ocu]i changes in hypnxie isehemic encepbalnpa ally(HIE)of new[x,rns. METHODS:One hundred and two newblt;~rns suffered from HIE were investi- gated to observe lhe pathological neular fundus changes by di~et ophthabnoseopy after mydria~s. RE- SULTS:Seventy seven ca.~s(154 eyes)were found to have ophthalmoscopic changes in the ~ular fundi including papilledema .white retina vaseolar abnormality and hemorrhage. CONCLUSIONS:In clinical view .the severity of HIE depends on the pathological ebanges of the brain .and ftmdus ahnormalby will be very often in middle and .~vere sufforers of HIE.
Idiopathic intracranial hypertension (IIH) is a neurological disease, characterized by increased intracranial pressure and papilledema, and often associated with headache, transient loss of vision and pulsatile tinnitus. IIH typically occurs in women of childbearing age. Over 90.0% of patients are with obesity or over weighted. Loss of sensory visual function is the major morbidity associated with IIH and some patients even develop into blindness. Most patients will have varied degrees of visual impairment, or even a few become blind. Frisén grading system, visual field examination and spectral-domain optical coherence tomography can be used to evaluate and monitor the IIH papilledema functionally and morphologically. In recent years, IIH treatment trials in other countries confirmed that, weight loss and low-salt diet combined with acetazolamide treatment has a clear improvement for IIH patients with mild visual impairment. In-depth understanding of the etiology, clinical manifestations, diagnostic criteria and the main treatment has important clinical significance for IIH patients
ObjectiveTo compare the clinical features of patients with acute Vogt-Koyanagi-Harada syndrome (VKH syndrome) of optic disc swelling (ODS) and serous retinal detachment (RD).MethodsA retrospective clinical study. From January 2013 to November 2019, 212 patients with acute VKH syndrome diagnosed in the Department of Ophthalmology of Shanghai Xuhui District Central Hospital were included in the study. Among them, there were 105 males (210 eyes) and 107 females (214 eyes). The average age was 40.84±13.90 years. All affected eyes were examined by BCVA, FFA, and OCT. The standard logarithmic visual acuity chart was used for BCVA examination, which was converted into logMAR visual acuity in statistics. According to the changes in the fundus, the patients were divided into the ODS group and the RD group, 36 patients with 72 eyes (16.98%) and 176 patients with 352 eyes (83.02%), respectively. The independent sample t test was performed to compare the age of onset, visit time and BCVA of the two groups of patients, the χ2 test was performed to compare the count data.ResultsAmong the 72 eyes of 36 patients in the ODS group, there were 16 males with 32 eyes (44.44%), 20 females with 40 eyes (55.56%). The average age was 40.56±16.57 years, the average visit time was 22.47±19.98 days, the average logMAR BCVA was 0.68±0.53. Among the 352 eyes of 176 patients in the RD group, there were 89 male patients with 178 eyes (50.56%), and 87 female patients with 174 eyes (49.43%). The average age was 40.90±13.34 years, the average visit time was 17.25±24.40 days, the average logMAR BCVA was 0.80±0.56. The average age (t=－0.116), gender composition ratio (χ2=0.448), average visit time (t=1.204), average logMAR BCVA (t=－1.661) comparisons between the two groups showed no statistically significant differences (P＞0.05). There was no statistically significant difference in the average logMAR BCVA between the RD group and the ODS group of different eyes (t=0.227, 0.810; P＞0.05). There were 50 (69.44%, 50/72) and 272 (77.27%, 272/352) eyes in the ODS group and RD group with inflammation of the anterior segment. There were anterior segment reactions between the two groups. There was no statistically significant difference in the number of eyes (χ2=1.003, P＞0.05). There were 34 (19.32%, 34/176) and 2 (5.56%, 2/36) patients with headache and hearing loss, respectively. The comparison of the number of patients with headache and hearing loss between the two groups showed statistically significant differences (χ2=4.015, P＜0.05).ConclusionCompared the patients with ODS acute VKH syndrome, the patients with serous RD acute VKH syndrome are more likely to have extraocular symptoms such as headache and hearing loss.
