The relationship between cVFD and MH stage, as well as the postoperative ellipsoid zone disruption were evaluated using Spearman's correlation test. RESULTS: Our analysis determined Spearman coefficient is 0.705 for the correlation between sLV and MH stage(P<0.01), 0.877 for the correlation between sLV and postoperative ellipsoid zone disruption(P<0.01) and 0.721 for the correlation between MD and postoperative ellipsoid zone disruption(P<0.01). A significant relationship was also detected between postoperative ellipsoid zone disruption and MH stage(r=0.470, P<0.05). Univariate regression analysis indicated that sLV and MD were associated with postoperative ellipsoid zone disruption(P<0.01, P<0.01, respectively). CONCLUSION: Postoperative cVFD is highly correlated with MH stage and postoperative ellipsoid zone disruption in patients with MH.展开更多

Material - Methods : A 46 – year old male presented in emergency ophthalmologic department complaining for difficulties in performing tasks related to color discrimination in his occupation (PC technician). The patient underwent a thorough ophthalmological examination and then he was referred to the neurological department for further evaluation. Results: The patient presented an atypical pattern of color perception disturbance. His best corrected visual acuity decreased progressively during hospitalization. He also experienced visual allesthesia paroxysmally (illusory left homonymous transpositions of subjects viewed in the right homonymous visual field). The visual field evaluation revealed homonymous left hemianopsia. Magnetic resonance imaging revealed glioblastoma multiforme confirmed by biopsy. Conclusions: A thorough ophthalmological and neuro-imaging control is suggested in patients with sudden color perception disturbance. Patients with temporal or occipital cortex damage may experience visual allesthesia.展开更多
