Abstract
Pediatric age group has a specific uveitis pattern, some diseases are more common than others in pediatric population. Pediatric uveitis may be infectious or non-infectious in etiology. The etiology of non-infectious uveitis is presumed to be autoimmune or autoinflammatory. Young children are often asymptomatic either because of inability to express complaints or because of the truly asymptomatic nature of their disease. Therefore, the diagnosis is often delayed and severe complications may be seen at the time of initial visit. Young children may not be cooperative for a complete ocular examination and subtle findings of intraocular inflammation such as trace cells may be easily missed in the early stages of the disease. Children, in general, tend to have more severe and chronic intraocular inflammation that frequently results in ocular complications and visual loss This study was conducted to report the etiologic and clinical features of uveitis in children seen at Mansoura ophthalmic center. This study included 63 children with uveitis who were attending uveitis outpatient clinic of Mansoura university Ophthalmic Center over the period between September 2019 and August 2021. Bilateral affection was observed in 34 cases, so the total number of included eyes was 97. After obtaining a written informed consent, the cases were subjected to full history taking and full ophthalmological examination including assessment of visual acuity, slit lamp examination, examination by autorefractometer and measurement of IOP. Topcon DRI OCT Triton plus was used to obtain retinal images Our study revealed that male prevalence was observed in the included cases and most of the included cases showed bilateral affection. The most frequent cause of uveitis is presumed trematode induced followed by JIA then idiopathic uveitis. The most common type of uveitis was anterior uveitis. The pathological examination revealed high prevalence of non-granulomatous type of uveitis. Most of the included cases show no marked affection of vision. The most common causes of vision loss in the included cases were cataract followed by dense vitritis and macular edema. The most frequent OCT findings were macular oedema followed by neurosensory detachment then CNV. The most common US findings were vitritis, followed by RD then combined vitritis & RD. FFA findings showed vascular staining, macular leakage, and combined vascular staining & leakage. Conclusion The anterior uveitis was the most common type of uveitis among the included cases in the study. The most common cause of uveitis in Mansoura, Egypt was presumed trematodes induced uveitis followed by juvenile idiopathic arthritis then idiopathic uveitis. Male prevalence was observed in the included cases and most of the included cases showed bilateral affection. Most of cases after aggressive and appropriate treatment had a chance to regain vision, and complicated cataract was found to be the commonest cause of diminution of vision in our study.
