Abstract
PURPOSE To compare various ocular thermography parameters in posterior scleritis (PS), choroiditis (choroidal granuloma [CG], Vogt-Koyanagi-Harada [VKH] syndrome), central serous chorioretinopathy (CSCR), and healthy controls. METHODS This retrospective, observational, comparative study evaluated cases undergoing ocular thermography between April 2017 and October 2023. The study groups included cases of PS, CG, and VKH, while the control group comprised CSCR cases and healthy individuals. Various thermography parameters were assessed, which were as follows: Ocular surface temperature (OST), central corneal temperature (CCT), average scleral temperature (ST), nasal scleral temperature (nST), temperature difference between both the eyes (∆t), and difference between scleral and corneal temperatures (ST - CCT, nST - CCT). RESULTS It was found that ∆t was significantly higher in the PS group compared to the CG ( P = 0.005), CSCR ( P = 0.0001), and control groups (dilated control: P =0.006, undilated control: P = 0.0001). ST - CCT and nST - CCT were significantly higher in the undilated control and CSCR groups and significantly lower in the PS group. ST - CCT and nST - CCT showed less difference in the affected eyes compared to contralateral healthy eyes of PS and CG cases. OST, CCT, ST, and nST displayed statistically insignificant differences across all groups. CONCLUSION It is advisable to focus on temperature differences between the affected and healthy eyes, or the difference between the central corneal and scleral temperature of the affected eye, utilizing parameters such as ∆t, ST - CCT, and nST - CCT. These composite parameters offer a more effective approach than individual measurements like OST, CCT, ST, and nST. Thermography can serve as a screening tool to suspect and differentiate PS.

Abstract
PURPOSE To study cases of Fuchs' uveitis (FU) diagnosed as uveitis other than FU at initial visits. METHODS A retrospective, observational chart review. Details of clinical presentation, initial diagnosis, treatment details, and follow-up before and after the diagnosis of FU was studied. RESULT Twenty eyes of 19 patients finally diagnosed with FU. Mean total follow-up was 39 months (range: 3-120 months, median: 30 months) and follow-up after diagnosis of FU was 18 months (range: 0-84 months, median: 11 months). Most of the cases were diagnosed with anterior plus intermediate uveitis at the presentation (n = 8, 42.1%) and received steroid treatment. Keratic precipitates (KPs) typical of FU developed after mean 5.4 months of presentation (range: 1-18 months, median: 2 months). Altered iris pattern was noted after 17 months of presentation (range: 2-70 months, median: 8.5). Vitritis of grades 1-2 was present in all eyes. Overlap of uveitis of other etiology (retinal vasculitis, presumed tubercular intermediate uveitis) was found in three patients. Systemic immune disease (systemic lupus erythematosus, pulmonary sarcoidosis) was present in two patients. No treatment for the ocular inflammation was given after the diagnosis of FU in any patient and no change in the pattern of FU was observed during further follow-up. CONCLUSION Evolving FU may lead to misdiagnosis and mismanagement. We suggest a conservative approach, withholding steroid treatment, allowing FU to evolve, in otherwise asymptomatic patients with white eye, mild to moderate anterior chamber (AC) and vitreous inflammation, absent posterior synechiae and normal fundus examination or fundus examination suggestive of resolved uveitis.

Abstract
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 Toxoplasma 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 Toxoplasma She was diagnosed with toxoplasa retinochoroiditis in OD and treated with intravitreal clindamycin injections, oral anti-Toxoplasma 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 Toxoplasma scar.

Abstract
Multiple evanescent white dot syndrome (MEWDS) is a rare form of posterior uveitis characterized by involvement in the posterior pole and mid-periphery. A viral etiology that provokes an immune-mediated response has been hypothesized to be the inciting factor of the pathology. Recently, there has been an increase in the literature regarding new-onset uveitis and reactivation of previously diagnosed cases of uveitis following COVID-19 vaccinations. The COVID-19 vaccination has been speculated to trigger an immunomodulatory shift in recipients, resulting in an autoimmune event. MEWDS following COVID-19 vaccination was reported in 31 patients. It was most commonly observed following the first dose, affecting 15 patients, and least commonly after the booster dose, in only one patient. MEWDS-like disease following anti-SARS-CoV-2 vaccinations was reported the most in 16 cases after the Pfizer-BioNTech vaccination (BNT162b2 mRNA). Most of these cases had Primary MEWDS without any previous history of a similar event in the past.

Abstract
PURPOSE To study the choroidal thickness (CT) and central macular thickness (CMT) in post-fever retinitis (PFR) and their correlation with visual acuity and treatment. METHODS A retrospective, observational study of patients presenting with PFR from 2013 to 2021 and with spectral domain optical coherence tomography (SD-OCT) (Heidelberg®, SpectralisTM, Heidelberg, Germany) images were included. The CT and CMT were measured at presentation and at the final visit. The CT was measured subfoveally and at points 2000 µm superior, inferior, medial, and lateral from the fovea using the caliper tool. RESULTS Seventy-nine eyes of 65 patients were included for this study. The mean age was 39.03 (±16.00) years with female preponderance of 53.84% (n = 35). Mean follow-up duration was 30 days. Mean CT at presentation and at follow-up was 254.12 µm and 241.51 µm, respectively. CT was decreased in majority of the eyes 67.1% (n = 53) from their baseline value. Mean CMTs at presentation and final visit were 454.8 µm and 223.7 µm, respectively. Best corrected visual acuity had a positive correlation with CMT (r = 0.340; P = 0.002) and negligible correlation with CT. A significant decrease in the mean CT was noted in patients who received doxycycline either alone or in combination with a steroid as compared to those who did not receive any treatment (P < 0.001). The significance of which is unknown presently. CONCLUSION CMT has a greater role in determining the final visual outcome than CT. CT can be reduced post-treatment with no effect on vision.

Abstract
OBJECTIVE To describe a case of bilateral retinal vasculitis due to presumed sarcoidosis and rickettsial retinitis complicated with neovascularization with tear biomarker analysis. METHODS A retrospective case report. RESULTS A 16-year-old male presented with bilateral retinal vasculitis and retinitis in both eyes with inferotemporal quadrant neovascularization in the right eye. Multimodal imaging revealed the presence of active inflammation in both eyes. Weil Felix test was positive with raised ACE levels. This patient was treated with local and systemic steroids, doxycycline, and laser photocoagulation followed by oral methotrexate therapy which resulted in clinical resolution with recovery of visual acuity. Tear biomarker analysis showed raised sICAM-1 and MMP-9 levels in both eyes which significantly reduced following treatment. CONCLUSION Ocular sarcoidosis with rickettsial infection is a rare association. Tear biomarkers correlated well with clinical and imaging manifestations. High index of suspicion and aggressive anti-inflammatory therapy can help control inflammation and restore good vision.

Abstract
Acute retinal necrosis is a progressive intraocular inflammatory syndrome characterized by diffuse necrotizing retinitis that can lead to a poor visual outcome, mainly from retinal detachment. The antiviral treatment approach for acute retinal necrosis varies as there are no established guidelines. We summarize the outcomes of acute retinal necrosis with available antiviral treatments. Electronic searches were conducted in PubMed/MEDLINE, EMBASE, Scopus, and Google Scholar for interventional and observational studies. Meta-analysis was performed to evaluate the pooled proportion of the predefined selected outcomes. This study was registered in PROSPERO (CRD42022320987). Thirty-four studies with a total of 963 participants and 1,090 eyes were included in the final analysis. The estimated varicella-zoster virus and herpes simplex virus polymerase chain reaction-positive cases were 63% (95% CI: 55-71%) and 35% (95% CI: 28-42%), respectively. The 3 main antiviral treatment approaches identified were oral antivirals alone, intravenous antivirals alone, and a combination of systemic (oral or intravenous) and intravitreal antivirals. The overall pooled estimated proportions of visual acuity improvement, recurrence, and retinal detachment were 37% (95% CI: 27-47%), 14% (95% CI: 8-21%), and 43% (95% CI: 38-50%), respectively. Patients treated with systemic and intravitreal antivirals showed a trend towards better visual outcomes than those treated with systemic antivirals (oral or intravenous) alone, even though this analysis was not statistically significant (test for subgroup differences P = 0.83).

Abstract
Anterior uveitis is the most common type of uveitis worldwide. The etiologies of anterior uveitis can be divided into infectious and non-infectious (idiopathic, autoimmune, autoinflammatory, trauma, and others). The viral pathogens most commonly associated with infectious anterior uveitis include Herpes Simplex Virus, Varicella-Zoster Virus, Cytomegalovirus, and Rubella Virus. Other emerging causes of viral anterior uveitis are West Nile Virus, Human-Immunodeficiency Virus, Epstein-Barr Virus, Parechovirus, Dengue Virus, Chikungunya Virus, and Human Herpesvirus type 6,7, and 8. Early recognition allows prompt management and mitigates its potential ocular complications. This article provides an updated literature review of the epidemiology, clinical manifestations, diagnostic tools, and treatment options for viral anterior uveitis.

Abstract
In the current literature, clinical registry cohorts related to ocular inflammation are few and far between, and there are none involving multi-continental international data. Many existing registries comprise administrative databases, data related to specific uveitic diseases, or are designed to address a particular clinical problem. The existing data, although useful and serving their intended purposes, are segmented and may not be sufficiently robust to design prognostication tools or draw epidemiological conclusions in the field of uveitis and ocular inflammation. To solve this, we have developed the Ocular Autoimmune Systemic Inflammatory Infectious Study (OASIS) Clinical Registry. OASIS collects prospective and retrospective data on patients with all types of ocular inflammatory conditions from centers all around the world. It is a primarily web-based platform with alternative offline modes of access. A comprehensive set of clinical data ranging from demographics, past medical history, clinical presentation, working diagnosis to visual outcomes are collected over a range of time points. Additionally, clinical images such as optical coherence tomography, fundus fluorescein angiography and indocyanine green angiography studies may be uploaded. Through the capturing of diverse, well-structured, and clinically meaningful data in a simplified and consistent fashion, OASIS will deliver a comprehensive and well organized data set ripe for data analysis. The applications of the registry are numerous, and include performing epidemiological analysis, monitoring drug side effects, and studying treatment safety efficacy. Furthermore, the data compiled in OASIS will be used to develop new classification and diagnostic systems, as well as treatment and prognostication guidelines for uveitis.

Abstract
PURPOSE Chikungunya is a re-emerging viral infection across the globe. The purpose of this article is to review the systemic and ophthalmic manifestations associated with chikungunya fever. METHOD A review of literature was conducted using online databases. RESULTS In this report, we have reviewed the presently available literature on uveitis caused by chikungunya and highlighted the current knowledge of its clinical manifestations, imaging features, laboratory diagnostics, and the available therapeutic modalities from the systemic and ophthalmic standpoint. CONCLUSIONS Ocular involvement in chikungunya infection may occur at the time of systemic manifestations or it may occur as a delayed presentation many weeks after the fever. Treatment relies on a supportive therapy for systemic illness. Treatment of ocular manifestation depends on the type of manifestations and usually includes a combination of topical and oral steroids.

Abstract
BACKGROUND Immunologic and inflammatory adverse effects following vaccination against COVID-19 are being reported. While some reactions may develop denovo others concern its immunogenic effect in patients with pre-existing inflammatory conditions. METHODS Retrospective consecutive patients diagnosed with ocular inflammatory manifestations within 8 weeks of receiving COVID-19 vaccination who presented to a tertiary eye care centre in South India. RESULTS Ninety-eight eyes of 67 patients presenting with ocular inflammatory manifestations within 8 weeks following COVID-19 vaccination were studied. The mean age was 43 years (+/- 14.82; range 19-80 years). The most common presentations were anterior uveitis (n = 31, 31.7%), followed by panuveitis (n = 24, 24.5%). The mean time to onset of symptoms was 25 days (+/- 15.48; range 2-55 days) following a dose of vaccine. Among all patients, 39 (58.2%) had a previous history of ocular inflammation. Mean presenting visual acuity was 0.4 (0-4) logMAR units and mean final visual acuity was 0.2 (0-4) logMAR units. The causes for reduced vision included of cystoid macular edema (n=2, 2%), chorioretinal atrophy (n=2.2%), optic atrophy (n=1.1%), retinal vascular occlusion (n=1.1%) and acute retinal necrosis (n=1.1%). CONCLUSION Infective and immunogenic adverse events should be watched out for after COVID-19 vaccination. It is difficult to establish causality for such manifestations, nevertheless, most of them were mild and had good final visual outcomes.

Abstract
Dengue fever is a significant global public health concern with increasing incidence over the past two decades. The symptoms range from mild to severe, including fever, headache, rash, and joint pain. Ocular complications are prevalent among hospitalized patients, estimated to be between 10% and 40.3%, with varying incidences based on the serotype and severity of dengue. These complications can be hemorrhagic or inflammatory and typically occur after the onset of fever. Modern diagnostic tools such as Optical Coherence Tomography (OCT) and Fundus Fluorescein Angiography (FFA) have enabled physicians to better understand the extent of ocular involvement and guide treatment. This article provides an updated overview of the various manifestations of dengue uveitis, including their diagnosis and treatment.

Abstract
AIM The aim of the study is to analyze visual fields defects (VFDs) in epidemic retinitis (ER). METHODS Patients with ER and Humphrey's visual field (HFA) 30-2 performed after resolution were studied. VFD severity grading was performed. Patients treated with oral doxycycline (Group-A) versus doxycycline-steroids (group-B) were compared. RESULTS Thirty-five eyes of 25 patients were studied. Nasal, inferior, temporal and central VFD were seen in 19 (54.2%), 13 (37.1%), 7 (20%) and 6 (17.1%) eyes, respectively. Grade 0, 1, 2 and 3 VFDs were seen in 4 (11.4%), 15 (42.8%), 12 (34.2%) and 4 (11.4%) eyes respectively. Seven eyes with ≥1 year of follow-up post-resolution also showed grade 0-3 scotomas. Mean severity of scotoma was grade 1.15 (Median: 1) and 1.42 (Median: 1.5) in groups A (n = 13) and B (n = 14), respectively (p = .637). CONCLUSION ER can cause VFD persisting long after resolution. Treatment with oral doxycycline without steroids was non-inferior to combined treatment with respect to VFD.

Abstract
INTRODUCTION Ocular toxoplasmosis is the leading cause of posterior uveitis worldwide, affecting individuals acrossdifferent age groups. The key to reducing vision loss includes prompt diagnosis and treatment. However, despite the prevalence of ocular toxoplasmosis, there has been little consensus regarding its pathophysiology,clinical features, diagnosis, and especially management. METHODS The data sources were literature reviews, including Pub Med and Medline databases. Search terms included toxoplasmosis, retinitis, vasculitis, vitritis, uveitis alone or in combination with, serum, aqueous, vitreous eye, ocular and review. RESULTS In this review paper, we have sought to provide an overview of the pathophysiology, epidemiology, and clinical features of the disease, both based on current literature and our own clinical experience. We have also discussed the use of serology, ocular fluid, and ophthalmic investigations that could further facilitate the diagnosis of ocular toxoplasmosis.Different management strategies have been reported worldwide, including newer approaches such as local therapy. CONCLUSION A better understanding of critical aspects of ocular toxoplasmosis will hopefully lead to reduced morbidity, including blindness associated with this condition.

INTRODUCTION Coronavirus disease (COVID-19) vaccines have been reported to have ocular side effects including scleritis and episcleritis. PURPOSE To report scleritis and episcleritis within a month following administration of COVID-19 vaccine. METHODS Retrospective case series. RESULTS 15 eyes of 12 consecutive patients with scleritis and episcleritis from March 2021 to September 2021 were included. The mean time of onset of symptoms in patients with scleritis was 15.7 days (range, 4-30) and for episcleritis it was 13.2 days (range 2-30). Patients received COVISHIELD™ (10 patients) and COVAXIN™ (2 patients). Five patients had denovo inflammation and seven had recurrent inflammation. Episcleritis patients were treated with topical steroids and systemic COX2 inhibitors while patients with scleritis were treated with topical steroids/oral steroids/antiviral medications depending on the aetiology. CONCLUSION Scleritis and episcleritis following COVID-19 vaccination are milder and do not require intensive immunosuppression except in rare cases.

Abstract
To demonstrate viral proteins/inflammatory cytokines in a patient with unilateral keratouveitis. Retrospective case report. A 70-year-old Asian-Indian male presented with acute onset of blurring of vision in the left eye (OS) of 2 days duration. He had was coronavirus disease 2019 (COVID-19)-positive 3 months earlier. He had undergone cataract surgery/retinal laser photocoagulation in both the eyes. The corrected distance visual acuity (CDVA) (Snellen) in the right eye (RE) (OD) and left eye (LE) (OS) was 20/20 and 20/80, respectively. OS showed decreased corneal sensation, Descemet's folds, mild stromal edema, and fine and pigmented keratic precipitates with anterior chamber 1+ flare and 1+ cells. Fundus evaluation showed scattered laser marks in the OD and temporal sectoral laser marks in OS. He was diagnosed with viral keratouveitis in OS. Tear samples were collected on Schirmer's strips and tear wash for mass spectrometry and cytokines, which had 368 and 451 viral proteins in the RE and LE, respectively, using nano liquid chromatography-mass spectrometry, which were more than controls. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and varicella zoster virus proteins were detected. Cytokine analysis using flow cytometer analysis showed higher inflammation in OS as compared to OD. The patient was treated with oral acyclovir and topical steroids and resulted in resolution of his keratouveitis. SARS-CoV-2 proteins were present in the tear sample 3 months after COVID-19. The presence of viral proteins does not indicate causality.

Abstract
Characteristics and course of known seasonal diseases of pre-coronavirus disease (COVID-19) pandemic era may or may not change during the pandemic. Labelling COVID-19 as a novel etiology for those seasonal diseases or considering it as coinfection is debatable. Appropriate investigations are required to rule out previously known etiologies before correlating it with COVID-19. Epidemic retinitis (ER) or post fever retinitis is one such entity with seasonal variation. Multiple seropositivity for various organisms has been reported for ER during pre-pandemic era. This may significantly increase during the pandemic as the possibility of coinfection with COVID-19 is high. In the absence of gold-standard tests to exclude previously reported causes of ER, one should not undermine the possible coinfection before considering ER as post-COVID-19 syndrome. A study of incidence and pattern of seasonal variation of ER before and during the pandemic is needed before presumptively associating it with COVID-19.

Abstract
Purpose To study the impact of the novel coronavirus disease-2019 (COVID-19) pandemic on incidence, seasonal variation, clinical presentation, and disease outcome of epidemic retinitis (ER) and to compare clinical outcomes with positive and negative COVID-19 serology. Methods This is a retrospective, observational study conducted at a tertiary eye care hospital from August 2020 to June 2022. A graph of ER cases against the month of presentation was compared with the graph of the COVID-19 pandemic in the same region. Cases presented before COVID-19 vaccination, with positive COVID-19 serology (Group 1) were compared with cases with negative serology (Group 2). Results One hundred and thirty-two cases of ER were seen. The least number of cases were seen during and immediately after the peak of the pandemic (May 2021-August 2021). COVID-19 serology was positive in 13 (22 eyes)/60 (21.6%) unvaccinated cases. Along with COVID-19, positive serology for other ER etiologies was seen in 5/13 cases (38.4%). All patients received oral doxycycline with/without steroids. Groups 1 and 2 included 22 and 21 eyes of 13 cases each. Macular edema resolved in 43.6 and 32 days in groups 1 and 2, respectively. Retinitis resolved at 1 month in both groups. Corrected distant visual acuity was 20/50 and 20/70 at the presentation, which improved to 20/20 and 20/25 in groups 1 and 2, respectively. Mean and median follow-up was 6 months and 4.5 months, respectively, in both groups. No complications or recurrences were seen. Conclusion No significant impact of the COVID-19 pandemic on ER was observed.

Abstract
Purpose To study the clinical presentation and treatment outcome of epidemic retinitis (ER) during pregnancy. Methods This is a retrospective, observational chart review of pregnant patients diagnosed with ER from January 2014 to February 2023. Demographic details, month of pregnancy at the onset of ocular symptoms, history of present illness, clinical manifestations, and treatment outcomes were studied. Results In 9 years, ER was seen in 86 females, of whom 12 (13.9%) were pregnant. Twenty-one eyes of those 12 patients were studied. Most of the patients presented in the sixth month of pregnancy (range: 5-9 months, mean: 6.3 months). Physicians diagnosed viral exanthematous fever in six, typhoid in three, and suspected rickettsia in one patient. Medical termination of pregnancy (MTP) was performed in two patients before presentation. Weil-Felix test was positive in five, Brucella in one, WIDAL in three, and coronavirus disease 2019 (COVID-19) IgG and dengue IgG in one patient each. Oral antibiotics were given in five patients (two post-medical termination of pregnancy [MTP]) for the retinitis. All except four received oral steroids. Mean presenting corrected distant visual acuity (n = 21) was 20/125 (range: 20/20-20/20,000), which improved to (n = 18) 20/30 (range: 20/20-20/240). Macular edema (n = 11) resolved in 33.18 days (range: 20-50 days), and retinitis (n = 13) resolved in 58 days (range: 30-110 days). Ocular and systemic examination of newborn was possible in two and the babies were normal. Conclusion ER is seen commonly at the beginning of the third trimester. Lack of antibiotics may delay the resolution of retinitis. Ocular health needs to be assessed in larger series to conclude absence of retinal involvement in newborns.

Abstract
Acute retinal necrosis (ARN) as the term suggests is recognized as necrotic inflammation of retina, in contrast to toxoplasma retinochoroiditis where involvement of choroid can be appreciated as choroidal thickening on optical coherence tomography scan during active stage. Secondly, sequelae of ARN, such as chronic anterior uveitis and cystoid macular edema, could be challenging to manage as steroid use in various forms poses a risk of virus reactivation. We present a case of ARN caused by varicella zoster virus with an initial confusing clinical picture with toxoplasma retinochoroiditis, documented with choroidal involvement. The patient also developed a chronic anterior uveitis with macular edema after resolution of ARN which was treated with topical interferon (IFN) alfa 2b therapy with successful outcome. This report supports the recently described choroidal involvement in ARN and suggests topical IFN as a novel treatment in management of chronic macular edema post ARN.

Abstract
BACKGROUND Ocular inflammatory events following COVID-19 vaccination have been reported in the adult population. METHODS Multinational case series of patients under the age of 18 diagnosed with ocular inflammatory events within 28 days of COVID-19 vaccination. RESULTS Twenty individuals were included. The most common event was anterior uveitis (n = 8, 40.0%), followed by intermediate uveitis (7 patients, 35%), panuveitis (4 patients, 20%), and posterior uveitis (1 patient, 5%). The event was noticed in the first week after vaccination in 11 patients (55.0%). Twelve patients (60.0%) had a previous history of intraocular inflammatory event. Patients were managed with topical corticosteroids (n = 19, 95.0%), oral corticosteroids (n = 10, 50.0%), or increased dose of immunosuppressive treatment (n = 6, 30.0%). Thirteen patients (65.0%) had a complete resolution of the ocular event without complications. All patients had a final visual acuity unaffected or less than three lines of loss. CONCLUSION Ocular inflammatory events may happen in the paediatric population following COVID-19 vaccination. Most events were successfully treated, and all showed a good visual outcome.

Abstract
A group of self-limiting and frequently neglected diseases exist in the literature like Rickettsial disease, Malaria, Dengue fever, Chikungunya, West Nile virus infection, Rift Valley fever, Bartonellosis, or Lyme disease which are poorly understood due to lack of proper diagnostic testing. Currently, multimodal imaging has become a critical modality in the diagnosis and management of ocular diseases. Optical coherence tomography (OCT) is one such remarkable imaging modality in the field of ophthalmology providing high-resolution, cross-sectional images of the retina and choroid with the recent advances such as enhanced depth imaging and swept source OCT. Additionally, OCT angiography (OCTA) has further revolutionised dynamic imaging of retinal and choroidal vasculature non-invasively. This review article highlights the OCT and OCTA biomarkers in the diagnosis and prognosis of the aforementioned neglected diseases.
