Outcome of cataract surgery in children with presumed trematode-induced granulomatous anterior uveitis.

PURPOSE: To examine the 6-month visual outcomes and complications following cataract surgery in patients with persumed trematode induced granulomatous anterior uveitis. SETTING: Assiut university hospital, Assiut, Egypt. DESIGN: This is a retrospective non comparative case series study. METHODS: Patients presenting with significant cataract secondary to uveitis caused by trematode induced anterior chamber granuloma were included in this study. Cases with active anterior uveitis, within the last 3 months preceding surgery, and those with a history of trauma, were excluded from this study. Data collected included demographic characteristics, history of the condition including when uveitis started, treatment received and history of other health conditions that may be relevant to uveitis.Complete opthalmologic examination including assessment of best corrected visual acuity (BCVA) and OCT macula, if possible, were done. These was repeated 1 week, 1 month, 3 months and 6 months after surgery. Specular microscopy was performed preoperatively and 3 months after surgery. Patients underwent cataract surgery with posterior chamber intra ocular lens and statistical analysis was performed to compare preoperative and postoperative BCVA and corneal endothelial cell counts. Postoperative complications were recorded. RESULTS: Five eyes of 5 patients were included in the study. All study eyes showed improvement in the post-operative visual acuity. A statistically significant improvement was observed in VA in the sixth postoperative month compared to the baseline measurements (p = 0.004). No statistically significant difference was observed between the preoperative and postoperative endothelial cell counts (p = 0.696). Cystoid macular edema did not occur as a postoperative complication. CONCLUSION: Visual outcomes of cataract surgery in eyes with persumed trematode induced granulametous anterior uveitis are favorable. No sight threatening complication was observed in our series.

Central retinal vein occlusion : an uncommon complication in sarcoidosis.

Sarcoidosis is a multi-system granulomatosis of unknown etiology, defined by the presence of epithelioid and gigantocellular granulomas, without caseous necrosis. Ocular sarcoidosis manifests mainly as bilateral granulomatous anterior uveitis. Occlusion of the central retinal vein in sarcoidosis is a rare manifestation, which is the particularity of our observation. We report the case of a patient presenting with unilateral central retinal vein occlusion associated with granulomatous anterior uveitis on the same side. Systemic manifestations and further investigations led to the diagnosis of sarcoidosis.

Berlin nodules: About 3 cases.

INTRODUCTION: Granulomatous uveitis is mainly defined by the nature of keratic precipitates and iris nodules. Anterior chamber (AC) granulomas, also known as Berlin nodules (BN), are circumscribed granulomatous nodules that form in the iridocorneal angle (ICA) in response to intraocular inflammation. CASES DESCRIPTION: We present three representative cases of anterior uveitis with berlin nodules to insist on the clinical features of this entity. Case 1: A female adult was referred to our department for bilateral redness and gradual blurry vision. Slit-lamp examination of both eyes (OU) found a yellow-white nodular mass at 6 o'clock on the peripheral iris with irido-crystalline synechiae, vitreous haze and blurred fundus. Purified protein derivative skin test revealed an induration of 20 mm. A diagnosis of presumed ocular tuberculosis was made. The patient received antituberculosis drugs and steroids with good evolution. Case 2: An 11-year-old girl presented for redness and pain OU. Anterior segment examination showed circumciliary congestion, epithelial microcystic edema OU and pearly vascularized lesion against the cornea in the right eye. Fundus examination was unremarkable. A diagnosis of definite ocular sarcoidosis was made based on accessory salivary glands biopsy. The patient was treated with teroids and controlled twice a week. Case 3: A 26-year-old male presented with a redness and pain of the left eye. The slit-lamp examination showed fine keratic precipitates with pearly white nodules within the AC. Fundus examination showed a chorioretinal lesion and occlusive vasculitis. Chest CT was consistent with milliary tuberculosis. Adequate therapy was initiated with favorable outcome. CONCLUSION: BN can be associated with various ocular manifestations of several diseases. They may be the first manifestation of systemic conditions and seem to be well managed with topical steroids.

How should we approach management of childhood onset chronic anterior uveitis refractory to adalimumab?

INTRODUCTION: The management of refractory juvenile idiopathic associated uveitis (JIAU) or childhood-onset chronic anterior uveitis (CAU) is a challenge. There is no clear consensus or evidence base for to suggest the most appropriate therapy after primary or secondary failure of biweekly adalimumab. In this scenario, most clinicians advocate switching to another anti-tumor necrosis factor alpha inhibitor; however, there are a variety of other disease modifying agents to choose from albeit with a differing levels of evidence. AREAS COVERED: We discuss how to define nonresponse and potential treatment options for patients with JIAU and CAU refractory to biweekly adalimumab. EXPERT OPINION: Uncontrolled CAU and JIAU remain one of the most challenging diseases to manage and can lead to irreversible loss of vision in a third of those affected. Amongst the possible choices, weekly adalimumab, infliximab, tocilizumab and abatacept have more evidence to support their use. JAK inhibitors seem to be a promising option. Golimumab and Rituximab has also been thought to be partially effective in some refractory cases, whereas IL-17, IL-23, and IL-12 inhibition along with apremilast seem not to be a therapeutic option currently. The route of administration should also be considered as there can be significant pros and cons for different children.

Viral infections and pathogenesis of glaucoma: a comprehensive review.

Glaucoma is a leading cause of irreversible blindness worldwide, caused by the gradual degeneration of retinal ganglion cells and their axons. While glaucoma is primarily considered a genetic and age-related disease, some inflammatory conditions, such as uveitis and viral-induced anterior segment inflammation, cause secondary or uveitic glaucoma. Viruses are predominant ocular pathogens and can impose both acute and chronic pathological insults to the human eye. Many viruses, including herpes simplex virus, varicella-zoster virus, cytomegalovirus, rubella virus, dengue virus, chikungunya virus, Ebola virus, and, more recently, Zika virus (ZIKV) and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), have been associated with sequela of either primary or secondary glaucoma. Epidemiological and clinical studies suggest the association between these viruses and subsequent glaucoma development. Despite this, the ocular manifestation and sequela of viral infections are not well understood. In fact, the association of viruses with glaucoma is considered relatively uncommon in part due to underreporting and/or lack of long-term follow-up studies. In recent years, literature on the pathological spectrum of emerging viral infections, such as ZIKV and SARS-CoV-2, has strengthened this proposition and renewed research activity in this area. Clinical studies from endemic regions as well as laboratory and preclinical investigations demonstrate a strong link between an infectious trigger and development of glaucomatous pathology. In this article, we review the current understanding of the field with a particular focus on viruses and their association with the pathogenesis of glaucoma.

Uveitis Associated with Juvenile Idiopathic Arthritis.

Juvenile idiopathic arthritis (JIA) is the most common cause of uveitis in children. While symptoms are usually mild, persistent eye inflammation could lead to severe complications and impaired vision. It is essential that JIA patients at risk are diagnosed with uveitis early, receive adequate treatment, and avoid developing complications, such as cataract, glaucoma, and amblyopia. The purpose of this mini-review is to summarize the screening strategies and clinical management for JIA-associated uveitis (JIA-U) as well as the current state of molecular markers linked to this condition. Because glaucoma is one of the most common causes of visual loss in JIA-U, special focus will be put on this serious complication. We conclude by describing the current evidence regarding the long-standing question of whether chronic anterior uveitis without arthritis may be the same disease entity as JIA-U.

Long term outcome and prognostic indicators in Posner Schlossman syndrome.

BACKGROUND: Posner Schlossman syndrome is a well-defined uveitis entity that is characterised by relapsing remitting unilateral anterior uveitis with markedly raised intraocular pressure. The aim of this study was to determine the risk factors for progression in patients with Posner Schlossman syndrome. METHODS: Ninety-eight patients were enrolled in a retrospective case series. Progression was defined as a composite endpoint of any of development of permanent glaucoma (in patients with no evidence of glaucomatous loss on presentation), corneal failure, or chronic inflammation. Relapse was defined as a resolving episode of inflammation not meeting the criteria for progression. RESULTS: Seventy seven percent of patients relapsed on average each 2.2 years. Forty percent of patients progressed. On univariate analysis, increased age at enrolment, immunocompromise at enrolment, the presence of glaucomatous optic neuropathy at enrolment, the performance of an anterior chamber tap and a positive anterior chamber tap were all associated with increased risk of progression. On multivariate analysis, age at enrolment, immunocompromise at enrolment, the performance of an anterior chamber tap, and the presence of glaucomatous optic neuropathy at enrolment were independently associated with increased risk of disease progression. CONCLUSIONS: Posner Schlossman syndrome is not a benign uveitis entity and risk of both relapse and progression are high. Older patients, immunocompromised patients, patients with glaucomatous optic neuropathy at enrolment and those with a positive anterior chamber tap are all at increased risk of progression.

Evaluation of Uveitis Induced in Rats by a Type I Collagen Peptide as a Model for Childhood Arthritis-associated Uveitis.

Chronic asymptomatic and acute symptomatic anterior uveitis are forms of ocular inflammation associated with juvenile idiopathic arthritis (JIA) Chronic JIA-associated uveitis is characterized by young age of onset, female predilection, oligoarthritis, and antinuclear antibody (ANA) positivity. Acute JIA-associated uveitis predominantly affects older male juveniles who also develop enthesitis. A type I collagen-derived peptide (melanin-associated antigen [MAA]) induces anterior uveitis in rodents. In this study, we evaluated MAA-induced uveitis in rats as a potential model for JIA-uveitis. We characterized MAA-induced uveitis by assessing its relationship to age and sex; tracking the occurrence of arthritis, enthesitis, and ANA positivity; and measuring vitreous fluid inflammatory biomarkers. Juvenile and adult and male and female Lewis rats (Rattus norvegicus) were inoculated with MAA. Slit-lamp biomicroscopy, indirect ophthalmoscopy, and joint examinations were performed 3 times weekly. Rats were euthanized at 4 wk after MAA inoculation, and plasma ANA testing, vitreous inflammatory biomarker assays, and globe histopathology assessments were conducted. Uveitis, arthritis, ANA status, levels of inflammatory biomarkers, histopathology, and joint tomographic images were assessed in relation to age and sex and compared with nonuveitic controls. All MAA-immunized rats developed uveitis characterized by anterior chamber fibrin, iridal vessel dilation, and miosis, and uveal and choroidal lymphocytic infiltration. Levels of the vitreous fluid biomarker CCL5 were higher in uveitic rats compared with control rats. Time to uveitis onset, clinical uveitis scores, and biomarker levels did not differ based on age or sex. None of the MAA-exposed rats had arthritis, enthesitis, or ANA. None of the rats inoculated with MAA that had been treated with matrix metallopeptidase 1 had clinical, histologic, or immunohistochemical evidence of ocular inflammation. In contrast to JIA-associated uveitis in humans, MAA-induced uveitis in rats is not associated with age or sex predilections and MAA is not arthritogenic.

Incidence of and Risk Factors for Cataract in Anterior Uveitis.

PURPOSE: To estimate the incidence/risk factors for cataract in noninfectious anterior uveitis. DESIGN: Retrospective multicenter cohort study (6 US tertiary uveitis sites, 1978-2010). METHODS: Data were harvested by trained expert reviewers, using protocol-driven review of experts' charts. We studied cataract incidence-newly reduced visual acuity worse than 20/40 attributed to cataract; or incident cataract surgery-in 3923 eyes of 2567 patients with anterior uveitis. RESULTS: Cataract developed in 507 eyes (54/1000 eye-years, 95% CI 49-59). Time-updated risk factors associated with cataract included older age (≥65 vs <18 years: adjusted hazard ratio [aHR] 5.04, 95% CI 3.04-8.33), higher anterior chamber cell grade (P(trend)=0.001), prior incisional glaucoma surgery (aHR 1.86, 95% CI 1.10-3.14), band keratopathy (aHR 2.23, 95% CI 1.47-3.37), posterior synechiae (aHR 3.71, 95% CI 2.83-4.87), and elevated intraocular pressure ≥30 vs 6-20 mm Hg (aHR 2.57, 95% CI 1.38-4.77). Primary acute (aHR 0.59, 95% CI 0.30-1.15) and recurrent acute (aHR 0.74, 95% CI 0.55-0.98) had lower cataract risk than chronic anterior uveitis. Higher-dose prednisolone acetate 1%-equivalent use (≥2 drops/day) was associated with >2-fold higher cataract risk in eyes with anterior chamber cell grades 0.5+ or lower but was not associated with higher cataract risk in the presence of anterior chamber cells of grade 1+ or higher. CONCLUSIONS: Cataract complicates anterior uveitis in ∼5.4/100 eye-years. Several fixed and modifiable risk factors were identified, yielding a point system to guide cataract risk minimization. Topical corticosteroids only were associated with increased cataract risk when anterior chamber cells were absent or minimally present, suggesting their use to treat active inflammation (which itself is cataractogenic) does not cause a net increase in cataract incidence.

Features of hemodynamic and immunological parameters in patients with recurrent uveitis complicated by hypertension, Fuchs heterochromic uveitis and Posner-Schlossman syndrome.

Introduction: Uveitis is a disease that manifests with increased vascular permeability and occlusion, with some ischemia and inflammatory mediators. It is characterized by a wide range of pathological processes, including inflammation, increased vascular permeability and occlusion, local ischemia and cell alteration by inflammatory mediators, and is characterized by the presence of complications. Aim: To study the state of ocular hemodynamics by rheoophthalmography, as well as the immune status in patients with idiopathic recurrent anterior uveitis complicated by intraocular hypertension, Fuchs heterochromic uveitis, Posner-Schlossman syndrome, during the relapse period. Materials and methods: 93 patients with idiopathic recurrent anterior uveitis were included in this study, 8 patients with Fuchs' uveitis, and 6 patients with Posner-Schlossman syndrome. According to clinical signs, relapse and remission were considered. The control group (healthy volunteers of the same age) consisted of 27 people. In this regard, 5 groups of subjects were formed. The mean age of the patients was (M ± SD) 39.2 ± 14.6 years. According to the Median (range), the duration of the disease in patients was 2033 (350-3285) days, intraocular hypertension being recorded at P0 > 20 mm Hg. Statistical analysis was carried out in spreadsheets using STATISTICA 8.0 (StatSoft.Inc) program. Quantitative indicators were evaluated according to the correspondence to the normal distribution and to the Kolmogorov-Smirnov criterion. With a normal distribution, arithmetic means (M) and standard deviations (SD), limits of the 95% confidence interval (95% CI) and Student's t-test were calculated. Results: The volumetric blood filling of the eye according to the rheoophthalmographic indicator RQ during the period of remission of uncomplicated and complicated by hypertension anterior uveitis was reduced by 32.4%-40.5%, respectively, compared with the norm. During the period of relapse, RQ was significantly higher by 28% (p<0.05) than in remission, in the group of uncomplicated uveitis, and in the group of uveitis with increased IOP, no significant differences between the periods of remission and relapse were observed, which reflected the ischemic process in the relapse period. Volumetric blood filling in Fuchs and Posner-Schlossman syndromes in the acute period did not differ from the norm. Cellular immunity in the groups of uncomplicated and complicated by intraocular hypertension idiopathic uveitis, as well as with Fuchs and Posner-Schlossman syndromes, had a higher level of CD4 helper lymphocytes and a lower level of CD8 suppressor lymphocytes, which reflected higher values of the immunoregulatory index. The increase in the immunoregulatory index is most pronounced in Fuchs and Posner-Schlossman syndromes. Discussion: In the presented study, the incidence of idiopathic recurrent anterior uveitis complicated by intraocular hypertension was 9,9% among all cases of idiopathic recurrent anterior uveitis in one-time period. According to literature, this complicated form of uveitis occurs in 11,5%-46,1% of cases. Most often (up to 92% of cases), the anterior chamber angle was open. Conclusions: Different activity of the mechanisms regulating the balance of cellular and humoral immunity, sensitivity of T-cells to eye antigens in idiopathic anterior uveitis, Fuchs and Posner-Schlossman syndromes was assumed. Peculiarities of eye hemodynamics in these forms of uveitis were also revealed.

Cytomegalovirus Anterior Uveitis: Clinical Manifestations, Diagnosis, Treatment, and Immunological Mechanisms.

Little is known regarding anterior uveitis (AU), the most common ocular disease associated with cytomegalovirus (CMV) infection in immunocompetent populations. CMV AU is highly prevalent in Asia, with a higher incidence in men. Clinically, it manifests mainly as anterior chamber inflammation and elevated intraocular pressure (IOP). Acute CMV AU may resemble Posner-Schlossman syndrome with its recurrent hypertensive iritis, while chronic CMV AU may resemble Fuchs uveitis because of its elevated IOP. Without prompt treatment, it may progress to glaucoma; therefore, early diagnosis is critical to prognosis. Knowledge regarding clinical features and aqueous humor analyses can facilitate accurate diagnoses; so, we compared and summarized these aspects. Early antiviral treatment reduces the risk of a glaucoma surgery requirement, and therapeutic effects vary based on drug delivery. Both oral valganciclovir and topical ganciclovir can produce positive clinical outcomes, and higher concentration and frequency are beneficial in chronic CMV retinitis. An extended antiviral course could prevent relapses, but should be limited to 6 months to prevent drug resistance and side effects. In this review, we have systematically summarized the pathogenesis, clinical features, diagnostic and therapeutic aspects, and immunological mechanisms of CMV AU with the goal of providing a theoretical foundation for early clinical diagnosis and treatment.

Immunity status and expression of molecular markers (ICAM-1, CD5, CD25, CD95) on lymphocytes of patients with recurrent anterior uveitis complicated by macular edema.

BACKGROUND: Treatment of macular edema in uveitis is a key goal of treatment, because this complication remains a potential therapeutic problem for specialists. MATERIAL AND METHODS: Examination was carried out in 1-2 groups - 50 persons with uncomplicated recurrent anterior uveitis (AU) in the stage of relapse or remission - and 3-4 groups - 26 persons with recurrent AU complicated by uveitic macular edema (UME) in the stage of relapse or remission of AU. Control group - 27 healthy volunteers. All patients underwent an ophthalmologic examination, using OCT (Spectralis HRA + OCT (Heidelberg Engineering)). The state of cellular and humoral immunity and the expression of activation markers on blood lymphocytes in all patients were assessed. An immunohistocytochemical analysis using monoclonal antibodies (the peroxidase-anti-peroxidase method) was employed to assess the expression of lymphocyte activation markers. The monoclonal antibody panel (MCAP) for immunophenotyping included antibodies reacting with CD5, CD54 (ICAM-1), CD25, and CD95 (FAS) antigens. Immunophenotyping was performed using immunohistochemistry. RESULTS: In the patients with AU + UME, the parameters of the T-cell link of the immune response were increased and the parameters of humoral immunity (CD19, IgA, IgG) were decreased in comparison with the uncomplicated AU patients. The absolute and relative numbers of natural killer cells in the peripheral blood were higher, and the relative numbers of phagocytic neutrophils were lower in the group of anterior uveitis with UME than in uncomplicated AU. The absolute and relative expression levels of ICAM-1 (CD54) and the absolute expression level of CD5 on peripheral blood lymphocytes were increased in relapse at patients with AU + UME compared with uncomplicated AU. The expression levels of CD25 and CD95 were not different in these groups. CONCLUSION: Activation of cellular immunity markers ICAM-1 and CD5 seems to play a role in uveitic macular edema. The expression levels of CD25 and CD95 were not significantly different in these groups.

BILATERAL UVEITIS AND HYPOTONY FOLLOWING TREATMENT WITH TOPICAL CIDOFOVIR.

PURPOSE: To report a case of bilateral uveitis and hypotony associated with topical cidofovir treatment. METHODS: Case report. RESULTS: A 59-year-old diabetic man with HIV/AIDS presented with photophobia, ocular pain, and decreased vision. He was found to have bilateral hypotony, anterior uveitis, and serous choroidal detachments. Infectious disease workup, patient-reported history, and review of the patient's electronic medication list did not identify the etiology. Treatment with intensive topical corticosteroids led to resolution of uveitis and choroidal effusions within 3 months and resolution of hypotony within 9 months. Two years after his initial presentation, the patient developed acute recurrence of bilateral hypotony, anterior uveitis, and serous choroidal detachments shortly after intravenous cidofovir treatment. Careful reevaluation of the patient's outside medical records revealed that he had initiated treatment for rectal herpes simplex virus with compounded topical cidofovir one month before his initial presentation. CONCLUSION: To our knowledge, this is the first reported case of topical cidofovir causing ocular toxicity. Compounded and topical medications, like cidofovir in this case, may not appear on a patient's electronic medication list, so a focused review of outside medical records may be beneficial when a particular medication toxicity is suspected.

Atypical herpes zoster ophthalmicus with madarosis of upper eyelid, recurrent iridocyclitis and atrophic multifocal chorioretinopathy.

INTRODUCTION: Ocular involvement due to varicella-zoster virus (VZV) infection includes conjunctivitis, scleritis, keratitis, uveitis, and necrotizing retinitis. Non-necrotizing chorioretinopathy as a late manifestation has been described. CASE REPORT: A 50-year-old immunocompetent man developed herpes zoster ophthalmicus (HZO) in the right V1 dermatome with acute anterior uveitis (AAU) treated with oral valaciclovir and topical steroid and a chalazion in the upper eyelid with associated madarosis. Four months later, he presented recurrence of the AAU and multiple areas of chorioretinal atrophy on fundoscopy. Biopsy of the upper eyelid lesion revealed granulomatous inflammation of the eyelid margin and polymerase chain reaction study (PCR) tested positive for VZV-specific DNA. The iridocyclitis was resolved with oral valaciclovir at maximum doses with minimal choroidal pigmentary changes. DISCUSSION: VZV ophthalmic infection starts by reactivation from the trigeminal ganglion, and it spreads to the isthmus of the pilosebaceous follicles and the epidermis, which can cause involvement of follicle and sebaceous glands. Chorioretinopathy is a rare form of late-onset non-necrotizing herpetic uveitis characterized by atrophic-appearing hypopigmented lesions, the pathogenesis of which is unknown. A direct viral infection or secondary to occlusive choroidal vasculitis is postulated at the level of the choriocapillaris and more recently it has been referred to as "choroidal vitiligo" due to possible involvement of choroidal melanocytes, as occurs in cases of cutaneous vitiligo due to VZV infection.

The microbiome in HLA-B27-associated disease: implications for acute anterior uveitis and recommendations for future studies.

The pathogenesis of human leukocyte antigen (HLA)-B27-associated diseases such as acute anterior uveitis (AAU) and ankylosing spondylitis (AS) remains poorly understood, though Gram-negative bacteria and subclinical bowel inflammation are strongly implicated. Accumulating evidence from animal models and clinical studies supports several hypotheses, including HLA-B27-dependent dysbiosis, altered intestinal permeability, and molecular mimicry. However, the existing literature is hampered by inadequate studies designed to establish causation or uncover the role of viruses and fungi. Moreover, the unique disease model afforded by AAU to study the gut microbiota has been neglected. This review critically evaluates the current literature and prevailing hypotheses on the link between the gut microbiota and HLA-B27-associated disease. We propose a new potential role for HLA-B27-driven altered antibody responses to gut microbiota in disease pathogenesis and outline recommendations for future well-controlled human studies, focusing on AAU.

Etiology of Pediatric Uveitis in a Tertiary Pediatric Eye Hospital in Egypt.

PURPOSE: To report the causes of childhood-onset uveitis in a tertiary pediatric ophthalmology hospital in Egypt. METHODS: Retrospective study of the medical records of all uveitis patients following up at a tertiary pediatric ophthalmology hospital in Egypt from January 2017 to December 2020. RESULTS: The present study included 388 patients. The most common anatomical category was intermediate uveitis (30.4%), and around half of these children had pars planitis. This was followed by panuveitis (25.5%), posterior uveitis (23.5%), and anterior uveitis (20.6%), in decreasing frequency. Juvenile idiopathic arthritis, toxoplasmosis, and Vogt-Koyanagi-Harada syndrome were the most common causes of anterior uveitis, posterior uveitis, and panuveitis respectively. Cataract (40.5%), glaucoma (33.8%), and cystoid macular edema (31.6%) were the most frequent ocular complications. CONCLUSION: The present report provides the relative prevalence of the different anatomical types of uveitis, as well as their main causes in a cohort of Egyptian patients with childhood-onset uveitis.

Primary antibody deficiency-associated arthritis shares features with spondyloarthritis and enteropathic arthritis.

OBJECTIVE: The clinical spectrum of primary antibody deficiencies (PADs) and especially common variable immunodeficiency (CVID) includes various autoimmune disorders. We studied the prevalence and the features of articular rheumatic disease in a cohort of patient with PADs. METHODS: In this retrospective cohort study, complete clinical data of 268 patients with PADs, mainly consisting of patients with CVID, visiting the immunology outpatient clinic of a German tertiary hospital between 2018 and 2021 were collected. Those included case history, physical examination, laboratory as well as radiological findings. RESULTS: Inflammatory arthritis was diagnosed in 16.4% of studied patients and was significantly more common among patients with PAD-associated enteropathy (OR 13.39, p=0.0001), splenomegaly (OR 6.09, p=0.0001) or atopic diseases (OR 3.31, p=0.021). Given HLA-B27 status, the involvement of the axial skeleton and the presence of features, such as anterior uveitis, inflammatory bowel disease, psoriasis and/or dactylitis, 75% of studied patients fulfilled the Assessment of Spondyloarthritis International Society classification criteria. CONCLUSION: PAD-associated arthritis frequently shares features with spondyloarthritis (SpA) and enteropathic arthritis. The latter may suggest the interconnected pathomechanisms of inflammatory arthritis in SpA and PADs.

[BILATERAL OCULAR PLASMACYTOMA PRESENTING AS ACUTE ANTERIOR UVEITIS].

INTRODUCTION: A 64-year-old woman, presented to the ophthalmology outpatient clinic with abrupt onset of pain, blurred vision and redness in her right eye. Her medical history is remarkable for multiple myeloma, with successful bone marrow transplantation and recurrent disease as secondary plasma cell leukemia, managed with a biologic agent. Examination revealed severe fibrinous anterior uveitis, accompanied by keratic precipitates, rubeosis iridis and raised intra-ocular pressure (IOP) and normal fundus. The patient was treated intensively with topical steroids, IOP lowering agents, systemic acyclovir and prednisone. Response was partial, with further development of posterior synechiae, iris bombe and 360o angle closure. An anterior segment ultrasound demonstrated severely thickened iris. The appearance of bilateral sub-conjunctival salmon patches in both eyes facilitated histopathologic diagnosis by extraocular tissue biopsy which revealed plasma cells infiltration, suggestive of plasmacytoma. Ruthenium plaque radiotherapy administered in a 40Gy dose was initiated in both eyes with a new cycle of systemic chemotherapy. Complete regression after treatment was achieved bilaterally. AIMS: To report a case of bilateral ocular plasmacytoma presenting as an acute anterior uveitis. BACKGROUND: Plasmacytoma, associated with multiple myeloma, is a solid tumor of the lymphoid system composed of monoclonal plasma cells. Ocular involvement is rare and direct infiltration of both eyes is even rarer. METHODS: A case report. CONCLUSIONS: Extramedullary plasmacytoma rarely involves ocular structures. In the setting of systemic malignancy, ocular involvement should be considered, especially when acute inflammation is recalcitrant to therapy.

Covid-19 association with anterior uveitis (post-covid acute anterior uveitis).

The Covid-19 outbreak in Wuhan on 31st December 2019 soon became a pandemic. Ocular manifestations in post covid patients have been widely reported. Anterior uveitis is a common form of intraocular inflammation observed on a daily basis by Ophthalmologists. Diagnosis of AAU is relatively simple but identification of its etiology is difficult, specifically with Covid-19. Post Covid-19 AAU is not reported in Pakistan yet. The patient in the given case is investigated thoroughly, no possible cause of AAU is identified. The patient was managed for uveitis.
