Purpose: Pediatric uveitis poses unique challenges, characterized by difficulties in performing comprehensive examinations, potential delays in diagnosis, and a heightened risk of ocular complications. This study evaluate the etiologic and clinical characteristics of uveitis in children presenting to the Mansoura Ophthalmic Center, Mansoura, Egypt. Methods: A cross-sectional observational study was undertaken involving children diagnosed with uveitis attending the uveitis outpatient clinic at Mansoura University Ophthalmic Center. Comprehensive clinical evaluations were carried out, including detailed history taking and exhaustive ophthalmological examinations. Whenever deemed necessary, Spectral Domain Optical Coherence Tomography (OCT) and Fluorescein Fundus Angiography (FFA) were utilized to secure retinal images. An extensive systemic evaluation was also conducted to discern the diverse causes of uveitis among the participants. Results: The cohort comprised 63 children, impacting 97 eyes. Bilateral involvement was seen in 54% of cases, with a male predominance of 58.7%. The predominant etiologies of uveitis were presumed trematode-induced (36.7%), Juvenile Idiopathic Arthritis (JIA) accounting for 28.6%, and in 12.7% of cases, the cause remained undetermined. Anterior uveitis emerged as the primary presentation in 79.4% of cases. Regarding visual loss, cataract was the leading cause at 56.4%, followed by vitritis at 38.4%, and macular edema at 20.5%. Conclusion: Anterior uveitis was the most frequent presentation in our pediatric cohort. Despite the challenges, the majority of children with uveitis exhibited no significant visual impairment, with most causes of visual loss being reversible. [ABSTRACT FROM AUTHOR]

Aim: The aim of this research is to evaluate the demographic attributes and clinical manifestations of uveitis in adult patients frequenting the Mansoura Ophthalmic Center. Methods: Utilizing a cross-sectional, prospective, analytical study design, this research engaged adult patients visiting the outpatient uveitis clinic at the Mansoura Ophthalmic Center. Comprehensive case evaluations involved collecting detailed patient histories, examining ophthalmic records, and conducting thorough ocular examinations. These examinations encompassed the assessment of visual acuity, slit-lamp examination, and fundus examination. Furthermore, selected cases underwent optical coherence tomography (OCT) and fundus fluorescein angiography (FFA). Results: The Study involved an examination of 411 eyes belonging to 254 uveitic patients. In the Egyptian context, anterior uveitis surfaced as the most prevalent form of uveitis. The average Best-Corrected Visual Acuity (BCVA) among the cases studied was 0.797 ± 0.77 LogMAR, with the majority of cases demonstrating vision superior to 0.3 LogMAR. Notably, the principal causes of vision loss were generally reversible. Macular edema was identified as the leading cause of vision loss, representing 20.7% of cases as evidenced by OCT. The ratio of non-infectious to infectious uveitis stood at 92.2% to 7.8%. The most commonly observed etiologies of non-infectious uveitis included Behçet's disease (33.3%), Vogt-Koyanagi-Harada (VKH) syndrome (19.7%), idiopathic causes (19.2%), and ankylosing spondylitis (AS) (11.9%). Conversely, the most frequent infectious etiologies were trematode-induced uveitis (2.9%), herpetic uveitis (1.7%), toxoplasmosis (1.5%), tuberculosis (TB) (1.5%), and brucellosis (0.2%). Conclusions: This study conclusively indicates that anterior uveitis is the predominant anatomical type of uveitis in Egypt. Further, etiological diagnoses of uveitis should particularly emphasize Behçet's disease, VKH syndrome, and ankylosing spondylitis. [ABSTRACT FROM AUTHOR]

To outline posterior segment characteristics of presumed-trematode induced granulomatous uveitis. A cross-sectional case series. The study included 56 patients (60 eyes) presented with anterior chamber (AC) granulomas. Involvement of the posterior segment structures has been documented and reported. The mean age of the patients was 11.8 years (range 6–14 years). Posterior segment findings were vitritis in 9 eyes (15%), optic disc granuloma in 2 eyes (3.3%), optic disc hyperaemia in one eye (1.7%), macular oedema in 2 eyes (3.3%), epiretinal membrane in 3 eyes (5%), retinal vasculitis in one eye, a peripheral focus of retinitis in one eye (1.7%), and choroid thickening in 10 eyes (6.7%), with localised choroidal granuloma in one eye (1.7%). Presumed trematode-induced anterior chamber (AC) granuloma is not only restricted to the anterior segment of the eye, but posterior segment associations that may threaten vision should also be considered.

Purpose: Orbital myositis is a common cause of orbital inflammation with localized involvement of the extra ocular muscles. This study aimed to assess the value of infliximab in controlling orbital myositis and reducing its relapse rate. Methods: We conducted a retrospective review of the medical records of all consecutive patients with orbital myositis treated with infliximab between 2007 and 2016. We examined change in corticosteroid and immunomodulatory doses as well as relapse rates following treatment with infliximab. Results: The study included seven patients with an average follow up of 19 ± 13.4 months. The mean dose of systemic corticosteroid was reduced from 28.57 ± 14.35 mg/day at the time of infliximab initiation to 7.00 ± 6.83 mg/day at final follow-up (p =.003). Long-term remission was achieved in 85.7% (n = 6). Conclusion: This study supports the role of infliximab in treating refractory orbital myositis and this was associated with clinical improvement, decreasing relapse rate with dose reduction of conventional treatment.

To investigate the UBM characteristics of presumed trematode-induced granulomatous uveitis. Prospective case series. Thirty patients who presented with anterior chamber (AC) granuloma were included. UBM Imaging included Cornea, iris, AC angle, posterior chamber, ciliary body, and vitreous base. Thirty eyes were included with a mean age of 12.4 ± 2.5 years. UBM findings were retrocrneal membrane (33%), sub conjunctival nodule (10%), AC granuloma (100%); peripheral anterior synechia, granuloma-like lesion in posterior chamber; ciliary body edema with localized granuloma at specific site (100%), cataract in 30% either localized or generalized, and dot or thread-like high reflection on vitreous base in (20%). Presumed trematode-induced AC granuloma is common among children living in the rural areas of Egypt. UBM examinations can demonstrate various pathologic changes of anterior segment of the eye and provide objective evidence for the exact origin of those granulomas. [ABSTRACT FROM AUTHOR]

Aim: To investigate the longitudinal correlation between drusen characteristics and retinal layer volumes pre conversion and subsequent type of choroidal neovascularisation (CNV). Methods: This was a single-centre retrospective study. The study participants were patients with wet age-related macular degeneration (AMD) in one eye who developed wet AMD in the contralateral eye, with at least 2 years of follow-up prior to conversion. The Moorfields Eye Hospital database was searched for eligible patients and their data were recorded. Eyes were classified as occult or classic based on fundus fluorescein angiography. Optical coherence tomography (OCT) images were analysed for drusen characteristics and retinal layer volumes were analysed over time using automated software (Topcon 3D OCT-2000 and Orion, Voxeleron LLC, respectively). All values were obtained at baseline as well as year 1 and year 2 before conversion to wet AMD. Results: Fifty-one eyes with bilateral CNV showed high correlation of type of CNV between eyes (kappa statistic 0.89). A total of 49 wet AMD eyes (29 occult, 20 classic) were analysed for drusen parameters. Two patients with retinal angiomatous proliferation were excluded. Drusen count, area, and volume did not differ by CNV type, but the rates of change of drusen area (p = 0.046) and drusen volume (0.022) were higher in the occult group in the year preceding CNV development. Of the 49 eyes, 17 (10 occult, 7 classic) with available good quality OCT were analysed for retinal layer volumes. There was a progressive reduction in outer nuclear layer (ONL) volume (p = 0.002) and an expansion in outer plexiform layer volume (p = 0.015) in eyes that developed occult CNV. Conclusion: Our study shows that rate of increase in drusen load and reduction in ONL are significant features seen in eyes developing occult CNV, highlighting new imaging markers that need to be replicated in larger studies. These markers provide insight into the pathogenesis of CNV and may serve as prognostic indicators, as classic CNV carries a poorer prognosis compared to occult CNV. [ABSTRACT FROM AUTHOR]
