Visual system involvement in GFAP astrocytopathy: two case reports and a systematic literature review
<p>Background and Objectives: Glial fibrillary acidic protein (GFAP) antibodies can associate with an astrocytopathy often presenting as a meningoencephalitis. Visual involvement has been reported, but scarcely defined. We describe two cases of GFAP astrocytopathy with predominant visual symptoms and present a systematic review of the literature. Methods: We describe two patients with GFAP astrocytopathy from our neurology department. We performed a systematic review of the literature according to PRISMA guidelines, including all patients with this disease and available clinical data, focusing on visual involvement. Results: Patient 1 presented with bilateral optic disc edema and severe sudden bilateral loss of vision poorly responsive to therapy. Patient 2 showed bilateral optic disc edema, headache, and mild visual loss with complete recovery after steroids. We screened 275 records and included 84 papers (62 case reports and 22 case series) for a total of 592 patients. Visual involvement was reported in 149/592 (25%), with either clinical symptoms, or paraclinical test-restricted abnormalities. Bilateral optic disc edema was found in 80/159 (50%) of patients investigated with fundoscopy, among which 49/80 (61%) were asymptomatic. One hundred (100/592, 17%) reported visual symptoms, often described as blurred vision or transient visual obscurations. Optic neuritis was rare and diagnosed in only 6% of all patients with GFAP astrocytopathy, often without consistent clinical and paraclinical evidence to support the diagnosis. Four patients (including patient 1) manifested a severe, bilateral optic neuritis with poor treatment response. In patients with follow-up information, a relapsing disease course was more frequently observed in those with vs without visual involvement (35% vs 11%, p=0.0035, OR 3.6 [CI 1.44 - 8.88]). Discussion: Visual system involvement in GFAP astrocytopathy is common and heterogeneous, ranging from asymptomatic bilateral optic disc edema to severe bilateral loss of vision, but optic neuritis is rare. GFAP CSF antibody testing should be considered in patients with encephalitis/meningoencephalitis or myelitis and bilateral optic disc edema, even without visual symptoms, and in patients with severe bilateral optic neuritis, especially when AQP4 antibodies are negative. Visual symptoms might associate with a higher relapse risk and help to identify patients which may require chronic immunosuppression.</p>
Clinical assessment of the TechArm system on visually impaired and blind children during uni- and multi-sensory perception tasks
<p>Introduction</p> <p>This dataset includes the raw data linked with the paper “Clinical assessment of the TechArm system on visually impaired and blind children during uni- and multi-sensory perception tasks ”.</p> <p>In this paper, we validated the TechArm system on a pediatric population of visually impaired (low-vision and blind), and sighted children.</p> <p>Raw data concerning sighted children are collected in the first sheet, while raw data for visually impaired children are in the second sheet. Encoding is available in the third sheet.</p> <p>Methods</p> <p>8 blind children (B, mean age 10.50 ± 4.21 y.o.), 23 children with low vision (LV, mean age 92 9.87 ± 3.09 y.o.), and 23 age-matched sighted children (S, mean age 9.83 ± 3.01 y.o.) were enrolled in the study. Four TechArm units were used to deliver uni- (audio or tactile) or multi-sensory stimulation (audio-tactile) on the participant’s arm, and subject was asked to evaluate the number of active units (see Martolini et al, Brain Sciences, 2021 for a presentation of the protocol).</p> <p>Results (in brief)</p> <p>Results showed no significant difference among groups (normal or impaired vision). Overall, we observed the best performance in tactile condition, while auditory accuracy was around chance level. Also, we found that the audio-tactile condition is better than the audio condition alone, suggesting that multisensory stimulation is beneficial when perceptual accuracy and precision are low. Interestingly, we observed that for low-vision children the accuracy in audio condition improved proportionally to the severity of the visual impairment. Our findings confirmed the TechArm system's effectiveness in assessing perceptual competencies in sighted and visually impaired children, and its potential to be used to develop personalized rehabilitation programs for people with visual and sensory impairments.</p>
