Association of Fuchs Heterochromic Iridocyclitis with Multiple Sclerosis.

PURPOSE: To draw attention to the higher proportion of Fuchs heterochromic iridocyclitis (FHI) cases in patients with multiple sclerosis (MS). MATERIALS AND METHODS: Retrospective study of data collected at the Center for the Diagnosis and Treatment of Uveitis. RESULTS: An analysis of the medical records of 3016 patients with uveitis (in the years 2003-2020) was performed with a focus on MS. MS-associated uveitis was diagnosed in 90 patients (3%): anterior uveitis (n = 7), intermediate uveitis (n = 23), retinal vasculitis (n = 24), and panuveitis (n = 36). A clinical examination revealed signs of FHI in the anterior segment in 11 out of 90 cases (12%). Atypical manifestations of FHI included a higher incidence of bilateral involvement (45%), retinal vasculitis (27%), and vitreous snowballs (18%). The diagnosis of FHI preceded the diagnosis of MS in 4 cases. The median latency was 10.5 (range 8-15) years. In 4 patients, the diagnosis of demyelinating disease was established within one year of the diagnosis of FHI. We recommended a neurological examination for optic neuritis (n = 1), paresthesia (n = 3), relapse of motor deficit (n = 1), and screening of etiology in cases with involvement of the posterior segment (n = 3). In the other 3 cases, the diagnosis of MS preceded the diagnosis of FHI, with a median latency of 13 (range 8-19) years. CONCLUSION: We detected clinical symptoms of FHI in 12% of uveitis cases associated with MS, more often in bilateral manifestations of intraocular inflammation. Based on our experience, we recommend an investigation of the medical history of patients with FHI for manifestations of sensitive, sensory and motor deficits, especially in bilateral cases.

Prognostic factors of cataract surgery in patients with uveitis.

PURPOSE: To evaluate the long-term visual outcomes of patients with uveitis undergoing cataract surgery and to identify possible factors influencing the visual prognosis and the development of postoperative complications. METHODS: Retrospective study of all patients with uveitis who underwent cataract surgery between January 2015 and February 2020 in our tertiary referral center. RESULTS: A total of 78 eyes from 78 patients were included in the study. The best-corrected visual acuity (BCVA) improved in 86% of patients, and a BCVA of 0.5 or better was achieved in 57 (73%) patients. A significant correlation was shown between the preoperative and postoperative BCVA (Spearman r = 0.521, p < 0.01). Final BCVA differed between diverse anatomical uveitis entities (p = 0.047), and anterior uveitis demonstrated the best outcomes. Chronic uveitis resulted in a worse final BCVA than acute recurrent uveitis (p = 0.001). The presence of CME any time before the surgery and intermediate uveitis were associated with worse visual prognosis, while systemic therapy for uveitis before surgery and iris manipulation during surgery were not related to visual outcomes. Postoperative development of cystoid macular edema (CME) was closely associated with preexisting CME (p < 0.001) and intermediate uveitis (p = 0.01). CONCLUSIONS: Visual results of cataract surgery in patients with uveitis were beneficial, but limited visual outcomes were more frequently observed in patients with chronic uveitis and intermediate uveitis with a history of CME. In consequence, prevention, or adequate treatment of CME, especially in patients with intermediate uveitis, might result in better visual results of their cataract surgery.

The Incidence and Risk Factors of Optic Nerve Damage of Posner-Schlossman Syndrome: A Meta-Analysis.

Objective: To explore the incidence and associated factors of glaucoma optic nerve damage (GOND) among patients with Posner-Schlossman syndrome. Methods: We retrieved relative studies till July 2022 using databases including PubMed, CNKI, VIP, and Wan-Fang. The retrieval terms include "Posner-Schlossman syndrome", "Glaucomatocyclitic Crisis", and "visual field". The Chinese retrieval terms were the corresponding Chinese terminologies for the English terms mentioned above. The outcomes were the incidence of GOND among PSS patients, the male proportion, patient age, the proportion of patients with single eye affected, disease duration, and intraocular pressure during the episode in patients with or without GOND. Review manager 5.3 was used for the analysis. Results: In total, 19 studies were included in our analysis. The pooled incidence of GOND among PSS patients was 0.26 (95% CI = 0.16-0.43). Age [MD = 11.3(5.86, 16.73); P < .0001], disease duration [MD = 4.27 (3.38, 5.16), P < .00001], and single or double eye affected [RR = 0.69 (0.49, 0.98), P = .04] were significantly associated with the development of GOND. Whereas, gender [RR = 1.09 (0.91, 1.29), P = .35] and intraocular pressure at episodes [MD = 2.66 (-0.38, 5.7), P = .09] were not significantly associated with GOND development. Conclusion: A fraction of PSS patients ultimately develop GOND so physicians should not be highly optimistic about the prognosis of PSS patients and timely and effective treatment is very important. Patients of higher age, those with double eyes affected, and suffering from a long disease duration might be at a greater risk of developing GOND.

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.

A Case of Syphilis with a Rare Finding: Subretinal Hypopyon.

PURPOSE: To report clinical features and follow-up of a case with subretinal hypopyon due to syphilis infection. CASE PRESENTATION: We present a case of syphilis admitted with optic neuritis and treated with intravenous pulse steroids without antibiotics. The patient was referred to the uvea clinic in the follow-up because of decreased vision and the onset of multiple retinitis foci. We determined subretinal hypopyon in the left eye and a positive TPHA test. A significant regression was observed in retinitis and hypopyon with antibiotic therapy. CONCLUSION: Before starting a steroid treatment, infective etiologies should be considered in patients with optic neuritis. Treating with a high dosage of steroids without antibiotics in syphilis would worsen the clinical features and prognosis.

Multimodal Imaging Approach in a Patient with Vogt-Koyanagi-Harada-like Syndrome Due to Dabrafenib and Trametinib Use for Cutaneous Melanoma.

PURPOSE: To describe a case of ocular inflammation associated with dabrafenib and trametinib chemotherapy for cutaneous melanoma by using a multimodal image approach. MATERIALS AND METHODS: We report on a 51-year-old woman with Vogt-Koyanagi-Harada-like syndrome, which occurred while she was undergoing treatment with dabrafenib and trametinib for cutaneous melanoma. The patient complained of sudden, bilateral vision loss of 2 days' duration. Anatomical and functional improvement was observed after administration of systemic steroids and cessation of chemotherapy. Later on, 6 weeks after restarting dabrafenib, she had an episode of granulomatous anterior uveitis, which was successfully managed with topical mydriatics and steroids. Strict follow-up with multimodal imaging was performed until recovery. CONCLUSIONS: This report emphasizes the importance of strict ophthalmological follow-up with multimodal imaging in patients receiving dabrafenib and trametinib, and the need for a multidisciplinary approach in the management of ocular inflammation during chemotherapy.

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.

Intravitreal Fluocinolone 0.19mg Implant in the Management of Chronic Non-Infectious Uveitis: 12-Month Outcomes from a Single Tertiary Centre.

AIM: To present efficacy and safety of 0.19 mg fluocinolone acetonide insert (FAi) to treat chronic noninfectious uveitis (NIU) in a single referral center. METHODS: A retrospective observational clinical study of 11 eyes with NIU complicated by chronic cystoid macular edema (CMO). RESULTS: The main indication for treatment was chronic CMO in all 11 eyes. The mean central retinal thickness (CRT) at baseline was 435 µm ± 176, improving to 296 µm ± 67 at 12 months. Raised intraocular pressure (IOP) was the commonest adverse event. An IOP >21 mmHg was observed in three eyes, and >30 mmHg in one eye, managed with topical therapy. The mean best corrected visual acuity (BCVA) was stable at 12 months. There were no observed recurrences of uveitis. Two eyes received adjunctive treatment for worsening CRT. CONCLUSIONS: Our results suggest FAi is an effective maintenance treatment for NIU with favorable functional and anatomical outcomes.

Efficacy of B Cell Depletion Therapy with Rituximab in Refractory Chronic Recurrent Uveitis Associated with Vogt-Koyanagi-Harada Disease.

PURPOSE: To evaluate the efficacy of B cell depletion therapy with the chimeric mouse/human anti-CD20 monoclonal antibody rituximab for refractory chronic recurrent granulomatous uveitis associated with Vogt-Koyanagi-Harada (VKH) disease. METHODS: Retrospective study of 9 patients (18 eyes) who failed to respond to conventional combination immunosuppressive therapy. RESULTS: All the patients received 3 rituximab infusions. The follow-up period after initiation of rituximab therapy ranged from 9 to 36 months (mean ±SD, 19.2 ± 10.1). All patients achieved remission and visual acuity significantly improved (p < .001). Rituximab provided corticosteroid-sparing effect along with control of inflammation. No rituximab-related complications were observed. CONCLUSIONS: Rituximab is effective for the treatment of refractory chronic recurrent granulomatous uveitis associated with VKH disease.

Changes in Etiology of Uveitis in a Single Center in Japan.

Purpose: We investigated the changes in etiology of uveitis at the Uveitis Clinic of Tokyo Medical University Hospital in recent years.Methods: Medical records of patients with uveitis diagnosed between 2011 and 2017 (Group A) and between 2001 and 2007 (Group B) were reviewed.Results: 1,587 patients in group A and 1,507 patients in group B were analyzed. For noninfectious uveitis, frequencies of Vogt-Koyanagi-Harada disease, intraocular lymphoma (IOL) and iridocyclitis in young girls increased, while those of sarcoidosis and Behçet's disease decreased in the recent era. For infectious uveitis, herpetic iridocyclitis, ocular toxoplasmosis, ocular syphilis, and bacterial endophthalmitis increased, while acute retinal necrosis and ocular toxocariasis decreased. Unclassified uveitis decreased, whereas infectious uveitis and IOL increased due to the availability of new diagnostic tests.Conclusion: Etiologies of uveitis have changed over the years. Further development of novel tests and diagnostic criteria would increase definitive diagnosis for unclassified uveitis. (147/150 words).
