Assessment of Macular Capillary Perfusion by Optical Coherence Tomography Angiography on Quiescent Unilateral Anterior Pediatric Uveitis

Purpose: Using spectral domain optical coherence tomography angiography (SD-OCTA) to evaluate tomographic and microvascular parameters in the macula in quiescent unilateral anterior pediatric uveitis (APU) patients.Methods: Forty-two eyes of 21 patients diagnosed with unilateral APU and 21 eyes of 21 normal controls (NC) were included in this study. 6*6 mm macular scanning mode of SD-OCTA was used for all subjects. The central macular thickness (CMT), subfoveal choroidal thickness (SFCT), vascular density (VD) of superficial capillary plexus (SCP) and the deep capillary plexus (DCP), the foveal avascular zone (FAZ) area, and choriocapillary flow density (CFD) were analyzed and compared among affected, fellow, and NC eyes. Correlation analysis were used to evaluate the potential correlating factors with CFD.Results: DCP VD and CFD were significantly lower in quiescent affected eyes as compared to fellow and NCs eyes (DCP VD both p<0.001; CDF1.0: p=0.012 and p=0.003; CDF1.5: p=0.015 and p=0.006; CDF3.0: p=0.036 and p=0.010, respectively). SCP VD, DCP VD and CMT were significantly lower in the fellow eyes as compared to NC eyes (p=0.021; p<0.001; p=0.037, respectively); CFD was negatively correlated with FAZ and CMT in affected eyes and fellow eyes. No significant differences were detected in FAZ among the 3 groups (p > .05).Conclusions: As compared to NC eyes, both retinal and choroidal microvasculature were impaired in eyes with quiescent APU; retinal microvasculature in unaffected fellow eyes of unilateral APU was also impaired. OCTA is a useful technology for detection of subclinical microvascular changes in APU and may be useful as an additional prognostic tool.

P060 Childhood uveitis: epidemiological, clinical and etiological profile, about 52 cases

Background Childhood uveitis is a rare, often serious condition, and accounts for 2% to13% of all uveitis. It is characterized by an asymptomatic onset delaying the diagnosis and exposing a high risk of complications. The etiological profile of childhood uveitis seems to be different from that of adults. The objective of our work is to analyze the epidemiological, clinical, etiological, therapeutic and disease course characteristics of pediatric uveitis. Method This retrospective study, carried out in a tertiary care center, involved a number of 87 eyes in 52 children under the age of 16, collected over a period extending between January 2015 and September 2019 with a minimum follow-up of 6 months. Results The patients mean age was 8.15 years with a sex ratio of 1.47 and a mean consultation delay of 6.7 months. Uveitis was bilateral in 67.3% of cases. Pan-uveitis predominated, followed by intermediate, anterior and posterior uveitis in 50%, 21%, 17% and 12% of cases, respectively. Uveitis was idiopathic in 67.3% of cases. Inflammatory uveitis was the most frequent aetiology with 5 cases of Behçet's disease, 2 cases of juvenile idiopathic arthritis (JIA) and 2 cases of TINU syndrome. Ophthalmologic complications were dominated by iridocrystalline synechiae in 13.5%, retinal detachment in 10.4%, cataract in 5.4% and macular oedema in 2.7%. Corticosteroid therapy was administered to all children, combined with immunosuppressive therapy in 48% of cases (azathioprine, methotrexate). The use of anti-TNF alpha was justified in 11 patients. The disease course was marked by complete remission in 11 children and partial remission in 15 patients, 26 children presented relapses of their uveitis with satisfactory final visual acuity in 73% of cases. Conclusion Our results show the predominance of panuveitis, probably due to diagnostic delay. Idiopathic uveitis, as described in the literature, and inflammatory causes of Behçet's disease are at the top of the list of etiologies. Pediatric uveitis is a particular entity, which requires regular monitoring by a team of experts in order to avoid eye complications and amblyopia in the youngest.

Cataract Surgery with or without Intraocular Lens Implantation in Pediatric Uveitis: A Systematic Review with Meta-Analyses

Purpose. To systematically review the results of comparative studies of modern cataract surgery in pediatric uveitis with or without intraocular lens (IOL) implantation and to perform comparative meta-analyses to compare visual acuity outcomes and complication rates. Methods. On 12 November 2020, we systematically searched the Cochrane Central, PubMed/MEDLINE, EMBASE, ClinicalTrials.gov, and all affiliated databases of the Web of Science. Two authors independently reviewed studies and extracted data. Studies were reviewed qualitatively in text and quantitatively with meta-analyses. Outcome measures were preoperative and postoperative best-corrected visual acuity (BCVA), inflammation control, and rates of postoperative complications. Results. Ten studies of 288 eyes were eligible for review of which the majority were eyes with juvenile idiopathic arthritis-associated uveitis. Summary estimates revealed that the BCVA was better in pseudophakic eyes vs. aphakic eyes (1-year postoperative: −0.23 logMAR, 95% CI: −0.43 to −0.03 logMAR, P = 0.027 ; 5-year postoperative: −0.35 logMAR, 95% CI: −0.51 to −0.18 logMAR, P = 0.000036 ). Pseudophakic eyes had more visual axis opacification (OR 6.76, 95% CI: 2.73 to 16.8, P = 0.000036 ) and less hypotony (OR 0.19, 95% CI: 0.04 to 0.95, P = 0.044 ). Conclusions. In modern era cataract surgery on eyes with pediatric uveitis with IOL implantation leads to satisfactory and superior visual outcomes and no differences in complication rates apart from an increased prevalence of visual axis opacification and a decreased prevalence of hypotony when compared to aphakia. However, limitations of the retrospective design and the presence of selection bias necessitate a careful interpretation.
