Purpose: To present a case who developed Bell’s palsy while using interferon alpha 2a for Behçet uveitis.
Methods: A patient with Behçet disease presented with decreased vision in his right eye. Ophthalmic examination, fundus fluorescein angiography and optical coherence tomography were performed. After developing facial paralysis while on interferon therapy, the patient was referred to our neurology service for differential diagnosis and treatment.
Results: Examination of right eye revealed panuveitis with branch retinal vein occlusion, so high dose steroids were prescribed. In three days there was no improvement in terms of vitreous inflammation and so steroids were replaced with interferon. At the seventh month, patient experienced a facial paralysis. After eliminating other causes, including viral infections, trauma, cold exposure and neurological evaluation with cranial MRI, the patient was diagnosed to have Bell’s palsy by a neurologist. Interferon was replaced with mycophenolate mofetil and the Bell’s palsy was treated with oral steroids.
Conclusion: It is important to be alert to both common and rare complications while treating with interferon.
Objectives:The aim of this study was to identify the causes of visual impairment in children attending schools for students with visual impairment and to identify children suitable for treatment and rehabilitation.Materials and Methods:All students were examined in our department by a pediatric ophthalmologist and an ophthalmologist experienced in low vision and visual rehabilitation. The children’s medical histories were recorded. All children underwent ophthalmological examination including visual acuity measurement, anterior segment and dilated fundus evaluation, retinoscopy with cycloplegia, and intraocular pressure measurement. The causes of visual impairment were grouped as avoidable and unavoidable. Children with residual visual acuity better than 20/1250 were included in the low vision rehabilitation programme.Results:A total of 120 patients were evaluated and 79.2% were legally blind (visual acuity less than 0.05), 18.4% had low vision (visual acuity between 0.05 and 0.3), and 0.8% had normal vision (>0.3). The main causes of visual impairment were retinal dystrophies (24.2%) and retinopathy of prematurity (17.5%). Of all diseases related to visual impairment, 27.6% were avoidable. Improvement in visual acuity was achieved with low vision aids in 57.5% of all patients.Conclusion:The incidence of visual impairment due to avoidable causes can be decreased by ophthalmic screening. Treatment of these children in the early stages of visual development can improve visual acuity. Even in cases with delayed diagnosis, low vision aids are important for visual and neurobehavioral development, and these programmes may improve quality of life and education in these children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
