BACKGROUND/OBJECTIVES
Studies on uveitis in Sierra Leone were conducted prior to the Ebola Virus Disease epidemic of 2013-16, which was associated with uveitis in 20% of survivors. They did not include imaging or investigation of tuberculosis and used laboratory services outside the country. We performed a cross-sectional study on patients presenting with uveitis to establish their clinical characteristics and identify the impact of in-country laboratory diagnoses.
METHODS
We invited uveitis cases presenting to Eye Clinics in Sierra Leone from March to September 2022 to participate in the study. They underwent a diagnostic work-up, including fundus and ocular coherence tomography imaging. Active uveitis cases underwent further investigations including serology and immunological tests for syphilis, tuberculosis, herpetic viruses and HIV and chest radiographs.
RESULTS
We recruited 128 patients. The median age was 34 (IQR 19) years and there was an equal gender split. Panuveitis was the predominant anatomical uveitis type (n = 51, 40%), followed by posterior uveitis (n = 36, 28%). Bilateral disease affected 40 patients (31%). Active uveitis was identified in 75 (59%) cases. ICD 11 definition of blindness with VA < 3/60 occurred in 55 (33%) uveitis eyes. Aetiology of uveitis from clinical and laboratory assessment demonstrated that most cases were of undifferentiated aetiology (n = 66, 52%), followed by toxoplasmosis (n = 46, 36%). Trauma contributed to eight (6%) cases, syphilis to 5 (4%) cases and Ebola to 2 (2%).
CONCLUSIONS
Uveitis was associated with high levels of visual impairment. Posterior and panuveitis contributed to the highest proportion of uveitis cases. Laboratory studies helped differentiate syphilis as a significant aetiology of uveitis.

A woman in her late 30s presented with sudden diminution of vision, redness and pain in the right eye (OD) of 10 days' duration. Best corrected visual acuity (BCVA) was 20/160 in OD and 20/20 in the left eye (OS). Anterior segment of OD showed keratic precipitates, flare 3+, cells 2+ and a festooned pupil. Vitreous haze and cells were seen in OD. Frosted branch angiitis (FBA) was seen in all quadrants in OD and old scar was seen in both eyes. Serum toxoplasma immunoglobulin G (IgG) was positive and IgM negative, and PCR of an aqueous humour sample was negative for She was diagnosed with toxoplasa retinochoroiditis in OD and treated with intravitreal clindamycin injections, oral anti- antibiotics and steroids. Three months later, her BCVA in OD was 20/40 with resolving inflammation. She presented 2 months later with a new focus of retinochoroiditis without FBA and an old scar.

Ocular Immunology and Inflammation May 2024To characterize and describe clinical experience with childhood-onset non-infectious uveitis.
OBJECTIVE
To characterize and describe clinical experience with childhood-onset non-infectious uveitis.
STUDY DESIGN
A multicenter retrospective multidisciplinary national web-based registry of 507 patients from 21 hospitals was analyzed. Cases were grouped as immune disease-associated (IMDu), idiopathic (IDIu) or ophthalmologically distinct. Characteristics of juvenile idiopathic arthritis-associated (non-HLA-B27-related) uveitis (JIAu), IDIu, and pars planitis (PP) were compared.
RESULTS
IMDu (62.3%) and JIAu (51.9%) predominated in young females; and IDIu (22.7%) and PP (13.6%) in older children, without sex imbalance. Ocular complications occurred in 45.3% of cases (posterior synechiae [28%], cataracts [16%], band keratopathy [14%], ocular hypertension [11%] and cystoid macular edema [10%]) and were associated with synthetic (86%) and biologic (65%) disease-modifying antirheumatic drug (DMARD) use. Subgroups were significantly associated ( < 0.05) with different characteristics. JIAu was typically anterior (98%), insidious (75%), in ANA-positive (69%), young females (82%) with fewer complications (31%), better visual outcomes, and later use of uveitis-effective biologics. In contrast, IDIu was characteristically anterior (87%) or panuveitic (12.1%), with acute onset (60%) and more complications at onset (59%: synechiae [31%] and cataracts [9.6%]) and less DMARD use, while PP is intermediate, and was mostly bilateral (72.5%), persistent (86.5%) and chronic (86.8%), with more complications (70%; mainly posterior segment and cataracts at last visit), impaired visual acuity at onset, and greater systemic (81.2%), subtenon (29.1%) and intravitreal (10.1%) steroid use.
CONCLUSION
Prognosis of childhood uveitis has improved in the "biologic era," particularly in JIAu. Early referral and DMARD therapy may reduce steroid use and improve outcomes, especially in PP and IDIu.

International Journal of Ophthalmology 2024To determine the common causes and visual outcome after treatment among uveitis and scleritis patients.
AIM
To determine the common causes and visual outcome after treatment among uveitis and scleritis patients.
METHODS
This is a retrospective cohort observational study. All consecutive clinical records of patients with newly diagnosed uveitis and scleritis over a 4-year period, from Jan. 1, 2017 to Dec. 31, 2020, were analysed. Data was collected at the presentation and included a follow-up period of one year.
RESULTS
A total of 288 patients were recruited during the study period. Anterior uveitis was the most common anatomical diagnosis (50.0%) followed by panuveitis (25.0%), scleritis (13.5%), posterior uveitis (6.9%), and intermediate uveitis (4.5%). Viral Herpes was the most common cause of infectious cases, while Vogt-Koyanagi-Harada (VKH) disease and human leucocyte antigen (HLA) B27 spondyloarthropathy were the leading causes of identifiable non-infectious cases. Majority of patients presented with unilateral, non-granulomatous uveitis with an absence of hypopyon. Anatomical locations like posterior uveitis and panuveitis, and visual acuity worse than 3/60 at presentation were the factors associated with poor visual outcomes (<0.05). About 60% of patients had an identifiable cause for the uveitis and scleritis, with nearly equal distribution of infectious (=85, 29.5%) and non-infectious causes (=84, 29.2%). About 14.5% of patients were clinically blind at 1y of follow-up. The most common complication in our uveitis patients was glaucoma (47.5%), followed by cystoid macula oedema (18.9%) and cataract (13.9%).
CONCLUSION
Uveitis and scleritis are important causes of ocular morbidity. They are potentially blinding diseases which can have a good outcome if diagnosed and treated early.

INTRODUCTION
Ocular toxocariasis is a rare disease, predominantly affecting children and young adolescents, and usually presenting as unilateral posterior uveitis. We report the case of a child with toxocariasis associated with serous retinal detachment.
OBSERVATION
A 8-year-old child with no previous history of toxocariasis was referred for a 1-year decline in visual acuity, unimproved by optical correction, with vitreous condensation on examination, without central or peripheral granulomas, and serous retinal detachment on OCT. The diagnosis was made after extensive questioning, with evidence of contact with dogs and positive serology. Medical treatment combining corticosteroid therapy and antiparasitic therapy was initiated, and the clinical picture improved.
DISCUSSION
Ocular toxocariasis is a rare infection, unilateral in 90% of cases. Its clinical manifestation in children is pars planitis, posterior uveitis with a posterior pole chorioretinal focus associated with vitreoretinal traction and/or peripheral granuloma. In our case, the patient presented with vitreous condensation only, with OCT serous retinal detachment and no peripheral or central granulomas. Positive plasma serology or ocular samples confirmed the diagnosis.
CONCLUSION
Ocular toxocariasis should not be ruled out in the absence of a typical clinical picture, and seropositivity enables confirmation of the diagnosis when clinical suspicion arises.

BACKGROUND
Fuchs uveitis syndrome (FUS) is a chronic intraocular inflammatory disease. It can lead to glaucoma which can be intractable to both medical and surgical treatment. In the present report, we describe our experience with GATT as a primary surgical option in the treatment of glaucoma secondary to FUS.
RESULTS
Four consecutive patients with FUS-associated glaucoma underwent GATT in a single institution. Case 1 was a 28-year-old pseudophakic male with a preoperative intraocular pressure (IOP) of 43 mmHg had unsuccessful circumferential cannulation; his IOP remained high after GATT and received trabeculectomy followed by Ahmed glaucoma valve (AGV) implantation to control IOP. Although IOP was stable following AGV, he required descemet membrane endothelial keratoplasty due to persistent corneal decompansation. He had a stable IOP of 12 mmHg over 21 months. Case 2 was a 42-year-old male with preoperative IOP of 35 mmHg and posterior subcapsular cataract had 360-degree GATT combined with phacoemulsification; his IOP reduced to 14 mmHg over 18 months. Case 3 was an 52-year-old pseudophakic male with a preoperative IOP of 28 mmHg had 360-degree GATT; his IOP remained stable at 10 mmHg over 18 months. Case 4 was an 47-year-old pseudophakic female with a preoperative IOP of 39 mmHg had 360-degree GATT; her IOP remained stable at 14 mmHg over 12 months.
CONCLUSION
GATT may be used as an initial approach in secondary glaucoma due to FUS. But, further evidence is still warranted to better ascertain the usefulness of GATT in this specific patient population.

PURPOSE
To ascertain whether the use of ultra-wide-field fluorescein angiography (UWFFA) at baseline visit alters the assessment of disease activity and localization, as well as the management of patients presenting to a tertiary uveitis clinic.
DESIGN
Retrospective comparison of diagnostic approaches.
METHODS
Baseline visits of 158 patients who presented to the Uveitis Clinic at the Byers Eye Institute at Stanford between 2017 and 2022 were evaluated by 3 uveitis-trained ophthalmologists (I.K., A.B., and H.G.). Each eye had undergone clinical examination along with ultra-wide-field fundus photography (UWFFP) (Optos Plc), spectral-domain optical coherence tomography (SD-OCT, Spectralis Heidelberg, Heidelberg Engineering) and UWFFA (Optos Plc) at the baseline visit. Investigators were asked to successively determine disease activity, localization of disease (anterior, posterior or both), and management decisions based on clinical examination and UWFFP and SD-OCT (Set 1) and Set 1 plus UWFFA (Set 2). The primary outcome was the percentage of eyes whose management changed based on the availability of UWFFA compared with Set 1.
RESULTS
The mean age of the patients was 46.9 ± 22.4 years (range, 7-96), and 91 (57.6%) were female. With Set 1 alone, 138 eyes (55.2%) were found to have active disease; localization was anterior in 58 eyes (42.0%), posterior in 53 eyes (38.4%), and anterior + posterior in 27 eyes (19.6%). With Set 2, 169 eyes of 107 patients had active anterior, posterior, or panuveitis. In comparison with Set 1, assessment with Set 2 identified additional 31 eyes (18.3%) with active disease (P = .006) and an additional 31 eyes (18.3%) having disease in both anterior + posterior segments (P < .001). Regarding the primary outcome, management was changed in 68 eyes (27.4%) in Set 2 compared with Set 1.
CONCLUSIONS
Baseline UWFFA may alter assessment of disease activity, localization, and management decisions compared with clinical examination with only UWFFP and SD-OCT for eyes with uveitis. Thus, UWFFA may be considered as an essential tool in the evaluation of patients with uveitis at the baseline visit.

Multiple evanescent white dot syndrome (MEWDS) is a rare inflammatory eye condition. We report an atypical case of MEWDS in a man in his 30s who presented with blurred vision (visual acuity 6/9), floaters and photopsia in his left eye. Funduscopy examination showed mild peripheral nasal vascular sheathing with subtle grey-white dots highlighted on fundus autofluorescence. As far as the authors are aware, this is the first case presentation whereby areas affected by MEWDS started in the peripheral retina and migrated centrally. Fluorescein angiography showed hyperfluorescent areas in wreath-like patterns nasally. Optical coherence tomography showed disruption of the ellipsoid zone and hyperreflective projections into the outer nuclear layer. The size of the involved area increased over 3 weeks and subsequently resolved over 4 months. Simultaneously, the patient's symptoms also resolved, without treatment. This case highlights the importance of multimodal imaging, especially ultrawidefield imaging in diagnosing MEWDS.
