Pediatric Uveitis

Uveitis is less common in children than in adults, and its diagnosis and management can be particularly challenging. Young children are often asymptomatic either because of inability to express complaints or because of the truly asymptomatic nature of their disease. Even in advanced cases, parents may not be aware of severe visual impairment until the development of externally visible changes such as band keratopathy, strabismus, or leukocoria. 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. In children who present with amblyopia or strabismus, a careful examination is required to rule out uveitis as an underlying cause. Delayed and variable presentations cause a distinct challenge in the diagnosis of uveitis in children, furthermore differential diagnosis also requires awareness of etiologies which are different from adults. There are unique forms of uveitis and masquerade syndromes in this age group, while some entities commonly encountered in adults are rare in children

Pattern recognition is a sequential process-accurate diagnosis and treatment 20 years after presentation

A 25-year-old woman presented with ophthalmic and neurological manifestations. Her ocular manifestations included bilateral uveitis, multifocal retinal phlebitis, vitreitis and multiple retinal haemorrhages. Her neurological manifestations included migrainous headaches with visual aura, transient sensory symptoms and posterior circulation Transient Ischemic Attack (TIA). Magnetic resonance imaging of the brain demonstrated lesions that involved the deep white matter lesions initially and progressed to also involve the juxta cortical white and deep grey matter and brain stem, but without further neurological manifestations. She was sequentially treated with intravenous and oral glucocorticoid, cyclophosphamide and mycophenolate mofetil, but she continued to suffer with persistent episodes of retinal haemorrhages. Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL), Susac syndrome and Behcet's disease were considered in the differential diagnosis. Genetic workup and clinical picture were not suggestive of the former two. Further history of oro-genital ulceration in younger age emerged, which pointed strongly towards a diagnosis of Behcet's disease with neurological involvement. She was treated with infliximab and methotrexate with complete resolution of her symptoms and withdrawal of corticosteroids for the first time in over two decades

Clinical Study Cellular Debris in the Anterior Vitreous in Silent Eyes of Behçet Patients as a Clue of Asymptomatic Ocular Involvement

properly cited. Purpose. To investigate if there is a prognostic implication of the presence of cellular debris in the anterior vitreous in patients with Behçet's disease (BD) without any ocular symptoms. Methods. One hundred and twenty eyes of 60 patients with BD were included in the study. The eyes were divided into two groups according to the presence of cellular debris in the anterior vitreous. The first group included 54 eyes which were cellular debris (+) (group A), and the second group included 66 eyes which were cellular debris (−) (group B). Fluorescein angiography (FA) was performed to all patients following routine ocular examination. Patients were called for the six monthly control visits to investigate possible new ocular involvement during followup. The Kaplan-Meier method was used to estimate survival curves. Results. Seven eyes (13%) in group A and four eyes (6.1%) in group B showed optic disc hyperfluorescence on FA ( = 0.2). None of the eyes with disc hyperflourescence on initial examination developed uveitis attacks in their followup. In Kaplan-Meier survival analysis there was a significant difference between the groups (group A 20.6% and group B 4.2%) by means of ocular involvement during their followup (log-rank = 6.85, = 0.009). Conclusions. Presence of cellular debris in the anterior vitreous may have prognostic implications in patients with BD screened for ocular involvement

Presumed Necrotizing Viral Retinitis after Intravitreal Triamcinolone Injection: Case Report

A 56-year-old man presented with anterior chamber inflammation, increased intraocular pressure, peripheral retinal infiltration, and generalized retinal arterial obstruction suggesting acute retinal necrosis five months after intravitreal triamcinolone acetonide injection (IVTA). He was treated with intravenous antiviral agents and aspirin. Shortly after treatment, retinal infiltrations were resolved, and partial recanalization of the obstructed vessel was observed. Viral retinitis may occur as an opportunistic infection following IVTA due to the local immune modulatory effect of the steroid; hence, close observation following IVTA is necessary
