Most cases are idiopathic (pars planitis); only few children presented associated systemic disease. Macular edema and severe vitritis at presentation are associated with increased risk of visual impairment. Cystoid macular edema is the main cause of visual impairment.

Uveitis is rarer in children than in adults. Patients with anterior uveitis comprised the largest group. Posterior uveitis in the pediatric population has a lower incidence than some decades ago. Visual prognosis of pediatric uveitis is improving, owing to an earlier diagnosis and a correct treatment.

Aim: To assess the morphological characteristics of uveitic macular edema studied with Spectralis optical coherence tomography (OCT) and to investigate the correlation between the tomographic features and visual acuity. Methods: 71 eyes of 55 patients underwent examination with Spectralis OCT (Heidelberg Engineering, Germany). Data was correlated with logMAR best-corrected visual acuity (BCVA). Results: Two morphological patterns were observed: cystoid macular edema (CME) in 69% and diffuse macular edema in 31% of eyes. BCVA was 0.2 in CME, 0.1 in diffuse edema (p = 0.008). Foveal thickness was 413.4 ± 212 µm in CME, 311.27 ± 53 µm in diffuse edema (p = 0.03). BVCA was 0.3 in eyes with serous retinal detachment (SRD), 0.2 in eyes without SRD (p = 0.02). BCVA was 0.4 in eyes with inner segment/outer segment (IS/OS) disruption, 0.1 in eyes with integrity of the IS/OS junction (p = 0.01). Conclusions: BCVA is negatively correlated with cystoid pattern, foveal thickening and SRD. Disruption of the IS/OS junction is associated with poor vision in uveitic macular edema.

Visual prognosis is good despite ocular complications. Incidence of macular edema seems to be higher when using OCT. Microperimetry may represent a useful tool in detecting alteration in retinal sensitivity that may supplement visual acuity in the follow-up of macular edema.

Purpose. To study epidemiology, clinical findings and visual prognosis of patients with Fuchs' Heterochromic Iridocyclitis (FHI). Methods. A retrospective analysis was performed on 158 patients with FHI. Thirty-five patients were observed only once; the remaining 123 had a mean follow-up of 30.7 months (50 of them had a mean follow-up of 63.5 months) and in those we assessed complications, medical and surgical treatment, and long-term visual prognosis. Results. Average age at uveitis diagnosis was 27.2 years and 18.3% of patients were children. Blurred vision (54.5%) and floaters (40.5%) were the most frequent presenting symptoms. Small to medium-sized keratic precipitates (95.6%), iris atrophy (86.8%), and vitreous opacities (91.2%) were the most common signs; the prevalence of cataract and IOP increase was 63.5% and 20.1%, respectively, and their incidence was 0.1 and 0.06 eye/year. Significant risk factor for visual loss was IOP increase at presentation (p = 0.02). At final examination 98% of the eye had a visual acuity ≥ 0.6, and topical (p < 0.001) and systemic (p < 0.001) corticosteroids therapy were used less frequently than before referral. Conclusions. FHI has a good visual prognosis, despite the significant incidence of cataract and glaucoma. A correct and prompt diagnosis might avoid unnecessary therapies and provide excellent visual outcomes.

To prospectively investigate morphologic and functional changes after intravitreal bevacizumab for persistent diffuse and clinically significant diabetic macular edema. In total, 26 eyes in 26 patients were treated with three intravitreal injections of bevacizumab (Avastin™) given at 4-week intervals. Study parameters included: visual acuity (VA), perceived visual improvement, central macular thickness as measured by Spectralis OCT, macular sensitivity and fixation pattern as measured by MP-1 microperimetry, and the incidence of ocular and systemic side-effects. At the time of follow-up, 76.9 % of eyes showed a significant improvement in VA (p = 0.012), 38.4 % showed a one-line improvement on the ETDRS chart compared with VA at day 0, 30.7 % showed a two-line improvement, and 7.6 % showed at least a three-line improvement. The mean central macular thickness was 447 microns at day 0 and 311.1 microns at follow-up (p = 0.003). The mean baseline macular sensitivity, by MP-1 microperimetry, was 8.29 dB; at follow -up, macular sensitivity had improved to 14.26 dB (p = 0.025). These results support further controlled trials on the efficacy of intravitreal bevacizumab in treating diabetic macular edema. Microperimetry and OCT are important tools in managing diabetic patients, providing a detailed study of the macular region, particularly when it is necessary to monitor the morphological and functional outcome after various interventions. A good correlation between retinal sensitivity and perceived visual performance was found.

Central serous chorioretinopathy may be the presenting symptom of Cushing syndrome in a patient with adrenocortical adenoma.

We report the clinical history of a child affected by Crohn's disease in which uveitis precedes intestinal involvement by years and occurs with the atypical features of anterior chronic inflammation complicated by unilateral optic disc edema, rather than recurrent anterior uveitis with sudden onset which has been more widely reported in inflammatory bowel diseases. The uveitis onset occurred 8 years before symptoms of the primary intestinal disease, while in inflammatory bowel diseases the intestinal inflammation typically precedes ocular symptoms, and ocular inflammation only occasionally precedes inflammatory involvement of the bowel.
