Background: The aim of the Posner-Schlossman Syndrome European Study Group (PSS-ESG) is to acquire a comprehensive dataset of European patients with PSS. Here, we present the first report on the study protocol and the clinical findings of the patients at baseline. Methods: The PSS-ESG is a retrospective, multicentre study designed to evaluate patients with PSS. The study, designed and driven by a European Expert Committee includes three datasets: (1) the baseline, (2) the follow-up and (3) the intraocular pressure (IOP)/glaucoma dataset. Results: A total of 11 centres adhered to the PSS-ESG and 107 patients were included (68 males, 39 females) mostly Caucasian (93.4%). At uveitis onset, the patient's age ranged between 11 and 76 years, (mean age: 42±15 years). Best-corrected visual acuity was >0.5 in 80.3% of the eyes, IOP was >40 mm Hg in 44% of the eyes. Keratic precipitates were found in 78.5% of the eyes. No flare or cells in anterior chamber were detected in 56% and 53% of the cases, respectively. PCR analysis on aqueous sample was positive for cytomegalovirus-DNA in 50.6% out of the 81 tested patients. Conclusions: The PSS-ESG is the first multicentre study aimed to collect a comprehensive dataset of patients with PSS in non-Asian countries. A middlde-aged Caucasian male with a low-grade anterior chamber inflammation, keratic precipitates, preserved visual acuity and marked increased in IOP seemed to be the standard PSS patient across the 11 uveitis and glaucoma centres participating in the PSS-ESG.

Objectives: To evaluate the long-term anatomical and functional prognosis of patients with retinal detachment (RD) secondary to acute retinal necrosis (ARN) treated with pars plana vitrectomy (PPV). Methods: This retrospective case series included 21 eyes from 21 patients with RD secondary to ARN. The study analyzed vitreous or aqueous biopsy results, the impact of antiviral therapy, time to retinal detachment, changes in visual acuity (VA), and anatomical and surgical outcomes. All cases underwent 23-gauge PPV with silicone oil tamponade, and an episcleral encircling band was used in 11 cases. All patients received systemic antiviral therapy at diagnosis. Results: Retinal reattachment was achieved in 91% of cases during follow-up, with an average follow-up period of 39.5 ± 36.8 months. The average time from ARN diagnosis to RD onset was 33.3 ± 27.5 days. VZV was detected in 10 eyes through PCR analysis. Significant differences in visual prognosis were found between macula-off and macula-on RD (p = 0.048). Eyes with optic nerve head inflammation had worse final VA (p = 0.010). No significant difference was observed between preoperative VA and VA at the end of follow-up (p = 0.665). Conclusions: VZV was the primary virus associated with ARN-related RD. Early involvement of the macula and optic nerve in retinitis negatively impacted the final visual prognosis. [ABSTRACT FROM AUTHOR]

Vogt–Koyanagi–Harada (VKH) is a rare multisystem inflammatory disease affecting the eyes, ears, brain, skin, and hair. The Coronavirus Disease 2019 (COVID-19) is a new contagious infection that might trigger the onset of VKH disease, as previously proposed for other viruses. Moreover, after the mass vaccination against SARS-CoV-2 worldwide, cases of VKH disease associated with COVID-19 vaccination have been reported. We present an overview of VKH and a comprehensive literature revision of all the VKH cases described after COVID-19 infection and vaccination, adding our experience. No differences have been found considering epidemiology and clinical findings of the disease compared to those reported in the no-COVID era. All of the patients promptly responded to systemic and local corticosteroid therapy with a good final visual prognosis. Different possible pathogenetic mechanisms underlying the onset of VKH after COVID-19 vaccination are discussed, while the presence of the HLA DR4 antigen as a genetic predisposition for the onset of the disease after COVID-19 infection and vaccination is proposed. VKH disease is one of the most frequently reported uveitic entities after COVID-19 vaccination, but a good response to therapy should not discourage vaccination. Nevertheless, ophthalmologists should be alerted to the possibility of VKH occurrence or relapse after COVID-19 vaccination, especially in genetically predisposed subjects. [ABSTRACT FROM AUTHOR]

The uveitides are a collection of over 30 diseases characterised by intraocular inflammation. Previous work demonstrated that the agreement among uveitis experts on diagnosis was modest at best with some pairs of experts having chance alone agreement on selected diseases. The Standardisation of Uveitis Nomenclature (SUN) is a17‐year collaboration among experts in uveitis, ocular image grading, informatics, and machine learning to improve clinical and translational uveitis research. The SUN "Developing Classification Criteria for the Uveitides" project used a rigorous, multi‐phase approach to develop classification criteria for 25 of the most common uveitic diseases. The project's phases were: (1) informatics; (2) case collection; (3) case selection; (4) machine learning; and (5) consensus review and publication. The results were classification criteria with a high degree of accuracy (93.3%–99.3% depending on anatomic class of the uveitis), the goal of which is to form the basis for future uveitis research.

Parvovirus B-19 (B19V) is a common infection in children, occasionally complicated by ocular manifestations. In patients infected with severe acute respiratory syndrome virus (SARS-CoV-2), many cases of bacterial, fungal, and viral co-infections have been described. We report on a case of bilateral conjunctivitis, keratitis, and anterior uveitis that occurred in a patient co-infected by B19V and SARS-CoV-2. A young nurse developed, 20 days after the onset of asthenia and fever, a maculopapular rash and, in the following month, B19V-related arthritis. Shortly after a course of antibiotics and corticosteroids and the resolution of the arthritis, she began to complain of hearing loss and tinnitus. A polymerase chain reaction for SARS-CoV-2, previously negative, turned out positive; IgM for B19V decreased while IgG increased and antinuclear autoantibody and rheumatoid factor test results were positive. Ear symptoms disappeared after a course of prednisone, but eye burning and itching appeared 2 weeks after the coronavirus disease 2019 (COVID-19) positive swab. Bilateral conjunctivitis, keratitis, and anterior uveitis were diagnosed, which responded completely to a topical corticosteroid and mydriatic therapy. No relapses were observed in the following 12 months. The onset and progression of the symptoms, along with the laboratory findings, suggest a double pathogenesis of the ocular manifestations: keratitis and uveitis, along with the ear symptoms, seem to be the expression of an autoimmune reaction to B19V infection, while the conjunctivitis was likely related to direct infection of the conjunctiva by SARS-CoV-2.

to study the clinical features of uveitis-glaucoma-hyphema (UGH) syndrome, particularly those useful for a differential diagnosis from unilateral hypertensive acute anterior uveitis. A retrospective chart review was conducted on the clinical features of 9 patients with UGH syndrome. These features were then compared with those detected in 50 patients with unilateral hypertensive acute anterior uveitis. Fine and pigmented keratic precipitates (p =.0002 and p =.00004, respectively), iris atrophy (p =.0122), hyphema and vitreous opacities > 2+ (p =.0003), and cystoid macular edema (p =.009) were statistically associated with UGH syndrome. These clinical signs show a high specificity, ranging from 58 to 100%; the presence of pigmented keratic precipitates in the setting of a unilateral acute hypertensive anterior uveitis has a sensitivity and specificity of 89% and 84%, respectively. In patients operated on for cataract, UGH syndrome can be differentiated from unilateral hypertensive acute anterior uveitis considering specific clinical signs. [ABSTRACT FROM AUTHOR]

To study the epidemiological and clinical features of uveitis post-COVID-19 vaccination. Retrospective chart review of patients presenting with uveitis after COVID-19 vaccination in tertiary uveitis services. In total, 25 patients, 76% females, mean age 43.2 years, were included. Uveitis occurred after Pfizer, Moderna, Astra-Zeneca and Covaxin vaccination. Anterior uveitis was the most frequent type of uveitis (56%). History of uveitis was found in 19 cases (76%), among whom 90.9% of the tested patients developed anti-Sars-CoV-2 spike antibodies after vaccination. In a mean follow-up of 5 months, one-line decrease in visual acuity was found in 12% of patients. During post-vaccine uveitis, 15.8% of cases needed an increase in their systemic therapy. According to Naranjo score, new-onset uveitis had a higher probability of being associated with vaccination (p <.01). COVID-19 vaccination can cause uveitis but has no significant impact on the visual prognosis after resolution. [ABSTRACT FROM AUTHOR]

To report a relapse of Vogt-Koyanagi-Harada (VKH) disease in a patient after COVID-19 vaccination. A VKH disease patient, well controlled on azathioprine therapy, presented a uveitis relapse eleven days after the first vaccination for COVID-19. She received an induction high-dose intravenous corticosteroid therapy, followed by oral therapy, which led to a complete recovery from the uveitis in two weeks. No relapses occurred in the following five months of follow-up. Despite high-dose corticosteroid therapy and azathioprine, and one dose only of vaccination, the patient resulted positive for anti-RBD spike COV19 antibody. Relapse of VKH disease can occur after COVID-19 vaccination, despite an appropriate immunosuppressive therapy is ongoing. It responds to the classic therapy for VKH, and a serological response to an incomplete COVID-19 vaccination can also be found [ABSTRACT FROM AUTHOR]

Background: Vogt–Koyanagi–Harada (VKH) disease is a form of uveitis that is rare in Western countries. The aim of this study was to report on the long-term real-life treatment and prognosis of VKH in Italy. Methods: The clinical features, complications, and final visual acuity were retrospectively evaluated in 38 patients with VKH (mean follow-up: 120 months) globally, according to oral or intravenous corticosteroid treatment at onset and subsequent immunosuppressive therapy. Results: The mean final visual acuity was 0.13 ± 0.4 logMAR, which was a significant increase from the baseline (p < 0.0001). The patients who received intravenous rather than oral corticosteroids relapsed less (p = 0.026), with fewer relapses/patient/month of follow-up (p < 0.0001), and showed less frequent sunset glow fundus (33.3% versus 55%) and more relapse-free cases after induction therapy (p = 0.007). Delayed immunosuppressive therapy (median: 180 days from the onset of symptoms) reduced the rate of sunset glow fundus. The onset of sunset glow fundus was associated with a worse final visual acuity (p = 0.006). Conclusion: The long-term prognosis of VKH is quite good. Intravenous corticosteroids given at the onset of VKH are more effective than oral corticosteroids. Even if it is not given immediately after symptoms onset, immunosuppressive therapy is able to reduce the incidence of sunset glow fundus and to improve the final visual prognosis.

Background: Juvenile idiopathic arthritis (JIA) is a rheumatic condition of childhood that is frequently associated with anterior chronic uveitis. Evidence suggests that uveitis may persist up to adulthood in some cases, possibly causing severe visual impairment. Methods: We conducted a retrospective study on a series of patients aged 16 years or older with JIA-related active uveitis who were referred to the Uveitis Service of Sapienza University of Rome from 1990 to 2019 to evaluate the characteristics of ocular disease in patients with JIA-associated uveitis (JIA-U) who still exhibit uveitis in adulthood. Data on clinical features, treatment, complications and visual outcomes were collected. Results: Twenty adults (85% female; median age 23.4 ± 6.6 years, range 16–38 years) with ongoing uveitis (35 eyes) were identified. The median age at JIA onset was 6.15 ± 2.9 years (range 2–10), and uveitis onset was 8.7 ± 4.7 years (range 3–20). The patients were observed in a median follow-up of 16 ± 7.7 years (range 4–35). Fifty-seven percent of affected eyes (20 eyes) had good visual acuity (>0.4 logMAR), while eleven percent of affected eyes (4 eyes) were blind (≤20/200). Uveitis required topical steroids and mydriatic/cycloplegic in all cases. Orbital steroid injection was performed in 13 eyes. Systemic corticosteroids and biologic drugs were used in 14 patients. Conclusions: Although the visual prognosis of JIA-U has improved in recent years, persistent uveitis up to adulthood is still observed. Therefore, protracted follow-up of JIA-U patients is warranted because of the high burden of delayed visual complications. [ABSTRACT FROM AUTHOR]

Purpose: To assess the frequency of clinical signs in patients with viral acute anterior uveitis (AAU), and their ability to differentiate viral versus non-viral AAU. Methods: 168 patients with AAU, including 84 with presumed viral etiology, were evaluated. Sensitivity, specificity, area under the curve (AUC), positive and negative predictive value were calculated for each clinical sign. The model built with these parameters was tested on a validation group comprising 66 patients with AAU. Results: The most useful clinical signs were unilaterality (sensitivity: 98.8%, specificity: 57.1%), intraocular pressure (IOP) ≥24 mmHg (sensitivity: 68.7%, specificity: 91.7%), and the association between the two (sensitivity: 68.7%, specificity: 95.2%). In the validation group, the model built with these parameters presented AUC of 0.939. Adding iris atrophy AUC increased to 0.97. Considering these signs, it was possible to diagnose viral uveitis in 93.9% of the patients. Conclusion: Unilaterality, IOP≥24 mmHg and iris atrophy are significant predictors of possible viral etiology in AAU. [ABSTRACT FROM AUTHOR]

To provide recommendations for diagnosis of vitreoretinal lymphoma (VRL). Literature was reviewed for reports supporting the diagnosis of VRL. A questionnaire (Delphi 1 round) was distributed to 28 participants. In the second round (Delphi 2), items of the questionnaire not reaching consensus (75% agreement) were discussed to finalize the recommendations. Presenting symptoms include floaters and painless loss of vision, vitreous cells organized into sheets or clumps. Retinal lesions are usually multifocal creamy/white in the outer retina. Other findings include retinal lesions with "leopard-skin" appearance and retinal pigment epithelium atrophy. Severe vitreous infiltration without macular edema is the most likely presentation. Diagnostic vitrectomy should be performed. Systemic corticosteroid should be discontinued at least 2 weeks before surgery. An interleukin (IL)-10:IL-6 ratio > 1, positive mutation for the myeloid differentiation primary response 88 gene and monoclonality are indicators of VRL. Multi-modal imaging (optical coherence tomography, fundus autofluorescence) are recommended. A consensus meeting allowed the establishment of recommendations important for the diagnosis of VRL.

Purpose: To study macular microvascular changes in ocular Behçet disease (OBD) using optical coherence tomography angiography (OCTA).Methods: Quantitative and qualitative analyses of OCTA were performed on 23 OBD patients with active or inactive uveitis and compared with healthy controls.Results: Deep capillary plexus (DCP) is the most frequently involved in OBD (p < 0.001). Its vessel density (VD) is reduced compared with controls in both active (p < 0.007) and inactive uveitis (p = 0.03). In inactive uveitis, VD is inversely related to the number of uveitis relapses (superficial capillary plexus: r = -0.694, p = 0.004; DCP: r = -0.541, p = 0.037) and it is significantly reduced in patients with a uveitis-free period ≥5 years compared with healthy controls (p < 0.038).Conclusions: Macular VD is reduced in Behçet patients with active and inactive uveitis, especially in DCP. In inactive uveitis, VD is inversely related to the number of ocular relapses and cannot be restored during time. [ABSTRACT FROM AUTHOR]

Purpose: To study epidemiology and clinical findings of cataract in HIV+ patients. Methods: A total of 32 HIV+ patients, 11 with uveitis/retinitis before surgery and 21 without, mean follow-up 44.9 ± 36.6 months, and 114 HIV- patients, 57 with uveitis/retinitis before surgery and 57 without, were retrospectively compared. Results: Visual acuity improved in all HIV+ patients (p < 0.001), who were younger (p = 0.01) and more frequently males (p = 0.027). HIV+ patients with uveitis prior surgery improved less (p = 0.046) than HIV- (p < 0.001); their anterior chamber inflammation was similar to baseline. Male sex (p = 0.005), younger age (p < 0.001), dyslipidaemia (p = 0.058), HBV+ (p = 0.037), and unilateral cataract (p = 0.001) were more frequent in HIV+ patients with senile cataract, but they showed the same postoperative course as HIV- patients. Conclusion: Cataract surgery in HIV+ patients is safe and effective. Uveitis prior to surgery did not significantly affect the postoperative course. Systemic comorbidities are more frequent in HIV+ patients with senile cataract than in HIV- subjects. [ABSTRACT FROM AUTHOR]

Purpose: To describe the epidemiology of macular edema (ME) in patients with uveitis.Methods: Review of articles listed on PubMed pertaining to uveitic ME.Results: Reported rates of uveitic ME ranging from 20% to 70%, depending on the ancillary tests used (fundus examination, fluorescein angiography, optical coherence tomography). Macular edema might develop due to uveitis itself, or occur as an adverse effect of drugs taken for different diseases. It is more frequently observed in adults than in children, in chronic uveitis, and in intermediate uveitis. Males with ankylosing spondylitis are more prone to develop ME than females. Three patterns of uveitic ME are observed, either isolated or in combination: cystoid ME, the most frequently encountered pattern seen in up to 80% of cases, diffuse ME and serous retinal detachment.Conclusion: Older age, chronicity of uveitis and intermediate uveitis are risk factors for the development of ME in patients with uveitis.

Ocular involvement is a common manifestation of inflammatory rheumatic diseases, often requiring a multidisciplinary collaboration between rheumatologists and ophthalmologists. The aim of this study was to standardize “red flags” for referral for rheumatologists and ophthalmologists using a Delphi consensus for the management of rheumatic diseases with ocular involvement. The scientific board comprised 11 Italian hospital-based rheumatologists (N = 6) and ophthalmologists (N = 5). A systematic review identified potential red flags for referral. The panel developed 19 statements consisting of (a) referral from ophthalmologist to rheumatologist (b) referral from rheumatologist to ophthalmologist and (c) overarching principles relating to multidisciplinary roles/goals and management. Voting was performed anonymously using an online Delphi method. Each participant expressed a level of agreement on each statement using a 5-point scale (1=“strongly disagree”; 5=“strongly agree”). Total cumulative agreement was defined as the sum of the percentage of response to items 4 (“agree”) and 5 (“absolutely agree”), consensus defined as ≥ 80% cumulative agreement for each statement. Positive consensus among 11 participants was reached for 15/19 (78.9%) statements. Statements not reaching consensus were discussed in a face-to-face meeting prior to the second vote (10 participants). Positive consensus was reached for all 19 statements, with final total cumulative agreement of 90-100%. This is the first Delphi consensus undertaken to standardize red flags for referral to rheumatologists and ophthalmologists for patients with rheumatic diseases and ocular involvement.

Ocular tuberculosis remains a presumptive clinical diagnosis, as the gold standard tests for diagnosing ocular tuberculosis are often not useful: Mycobacterium tuberculosis cultures require weeks to process on Lowenstein-Jenson media and have low yield from ocular samples; while acid-fast bacilli smears or polymerase chain reaction detection of M. tuberculosis DNA have low sensitivities. Thus, diagnosis is often based on suggestive clinical signs, which are supported by positive investigations: tuberculin skin test or interferon-gamma release assays; chest X-ray findings suggestive of pulmonary tuberculosis, and/or evidence of associated systemic tuberculosis infections in the absence of other underlying disease. The aim of this review is to provide an update on the methods of diagnosing ocular tuberculosis, and discuss the challenges of its diagnosis. We also suggest a step-ladder approach to a more accurate diagnosis of ocular tuberculosis by combining the available diagnostic tests. [ABSTRACT FROM AUTHOR]

Purpose: To investigate demographic, clinical features and complications of Italian patients with ocular Behçet's disease (BD) over time.Methods: Retrospective study of 385 patients examined from 1968 to 2011, 265 of whom had follow-up ≥ 12 months.Results: A significant increase in the proportion of females (p = 0.03) and anterior uveitis (p < 0.001), and a decrease in the complete type of BD in all patients (p = 0.003) and in males (p = 0.002), and in hypopyon (p = 0.024) were observed over time. Optic neuropathy (p < 0.0001), maculopathy (p = 0.002), retinal detachment, and retinal neovascularization (p = 0.02) decreased over time, with no difference between genders, concomitant with an increase in the use of immunosuppressive drugs (p = 0.003). Visual acuity ≤1/10 was detected more often in males than females (p = 0.003).Conclusions: A significant shift in clinical manifestations of BD patients was observed over 44 years. Immunosuppressive therapy succeeded in lowering ocular complications. The incidence of ocular BD is increasing in females, but visual prognosis is still worse in males. [ABSTRACT FROM AUTHOR]

Purpose. To study epidemiology, clinical findings and visual prognosis of patients with Fuchs’ Heterochromic Iridocyclitis (FHI). Methods. A retrospective analysis was performed on 158 patients with FHI. Thirty-five patients were observed only once; the remaining 123 had a mean follow-up of 30.7 months (50 of them had a mean follow-up of 63.5 months) and in those we assessed complications, medical and surgical treatment, and long-term visual prognosis. Results. Average age at uveitis diagnosis was 27.2 years and 18.3% of patients were children. Blurred vision (54.5%) and floaters (40.5%) were the most frequent presenting symptoms. Small to medium-sized keratic precipitates (95.6%), iris atrophy (86.8%), and vitreous opacities (91.2%) were the most common signs; the prevalence of cataract and IOP increase was 63.5% and 20.1%, respectively, and their incidence was 0.1 and 0.06 eye/year. Significant risk factor for visual loss was IOP increase at presentation (p=0.02). At final examination 98% of the eye had a visual acuity ≥ 0.6, and topical (p<0.001) and systemic (p<0.001) corticosteroids therapy were used less frequently than before referral. Conclusions. FHI has a good visual prognosis, despite the significant incidence of cataract and glaucoma. A correct and prompt diagnosis might avoid unnecessary therapies and provide excellent visual outcomes.

Purpose: To report on clinical features and outcome of severe bacterial keratouveitis.Methods: Twenty patients with severe bacterial keratouveitis treated with topical tobramycin and levofloxacin and oral levofloxacin were included. Main outcome measures were ulcers location, bacterial isolates, risk factors, visual prognosis.Results: Centrally located ulcer/abscess was present in 65% of patients. Contact lens (CL) wear was the most common risk factor (70%). Bacterial isolates were observed in 58% of patients, none resistant to tobramycin and levofloxacin. Pseudomonas aeruginosa was found in 47% of positive cases and in 64% of CL wearers. After therapy, the mean visual acuity improved significantly (p < 0.0001), particularly in contact lens wearers (p = 0.04) and in patients younger than 60 years old (p < 0.001).Conclusions: Pseudomonas aeruginosa is the most frequent cause of bacterial keratouveitis and CL wear the most common risk factor. Topical tobramycin and levofloxacin and oral levofloxacin are effective in the treatment of bacterial keratouveitis. [ABSTRACT FROM AUTHOR]

Behçet disease (BD) is a multisystem inflammatory disorder that is an important cause of morbidity worldwide. BD is most common along the ancient "Silk Road" route in the Far East and Mediterranean basin. The eye is the most commonly involved organ in BD patients. The prototypical form of involvement is a relapsing remitting panuveitis and retinal vasculitis. Less commonly, BD may present in the form of conjunctivitis, conjunctival ulcers, keratitis, episcleritis, scleritis, and extraocular muscle paralysis. Uveitis in BD carries significant implications for the patient, because it is a chronic recurrent disease characterized by explosive attacks of severe inflammation that may cause significant, cumulative damage to the intraocular structures. This review summarizes the epidemiology of systemic and ocular clinical features of BD with particular focus on risk factors, clinical characteristics, complications, and prognosis of BD-associated uveitis.

Aim: To assess the morphological characteristics of uveitic macular edema studied with Spectralis optical coherence tomography (OCT) and to investigate the correlation between the tomographic features and visual acuity. Methods: 71 eyes of 55 patients underwent examination with Spectralis OCT (Heidelberg Engineering, Germany). Data was correlated with logMAR best-corrected visual acuity (BCVA). Results: Two morphological patterns were observed: cystoid macular edema (CME) in 69% and diffuse macular edema in 31% of eyes. BCVA was 0.2 in CME, 0.1 in diffuse edema (p = 0.008). Foveal thickness was 413.4 ± 212 μm in CME, 311.27 ± 53 μm in diffuse edema (p = 0.03). BVCA was 0.3 in eyes with serous retinal detachment (SRD), 0.2 in eyes without SRD (p = 0.02). BCVA was 0.4 in eyes with inner segment/outer segment (IS/OS) disruption, 0.1 in eyes with integrity of the IS/OS junction (p = 0.01). Conclusions: BCVA is negatively correlated with cystoid pattern, foveal thickening and SRD. Disruption of the IS/OS junction is associated with poor vision in uveitic macular edema.

Purpose: To report clinical features and prognosis of HLA B27 acute anterior uveitis. Methods: 165 patients with recurrent acute anterior uveitis were divided into two groups: HLA B27-positive (group 1, 60 patients) and HLA B27-negative (group 2, 105 patients). A comparison between the two groups was performed. Results: Unilateral involvement was higher in group 1 ( p = .046), and more simultaneous bilateral cases occurred in group 2 ( p = .004). Group 1 was more correlated to systemic diseases than group 2 (50 versus 17.1%, p < .001), particularly to ankylosing spondylitis (35 versus 3.8%, p < .001). Uveitis was diagnosed before spondylitis in 57% of patients. In groups 1 and 2 an immunosuppressive therapy was administered to 20 and 9.5% of patients but was exclusively given to control uveitis in 1.6 and in 2.8% of cases, respectively. Conclusions: A strong association between HLA B27 uveitis and ankylosing spondylitis was confirmed and usually uveitis preceded rheumatological involvement. [ABSTRACT FROM AUTHOR]

Purpose: To study use of optical coherence tomography (OCT) for macular edema in uveitis. Methods: In total, 44 patients with uveitis and macular edema underwent OCT. Data obtained were correlated with anatomic type, duration of uveitis, and visual acuity (VA). Results: Both cystoid macular edema (CME) and diffuse macular edema (DME) correlate negatively with VA, although statistically CME showed stronger correlation (p = .02). Also CME had higher mean foveal thickness than DME (p < .01). Negative correlation between foveal thickness and VA (p < .05) was observed. CME correlates with uveitis duration (p < .01). Conclusions: CME and macular thickening correlate with VA reduction and uveitis duration. [ABSTRACT FROM AUTHOR]

Abstract Background. Turner's syndrome is a chromosomal abnormality where phenotypic females have either a missing X chromosome or a structural aberration of the X chromosome. Several ocular diseases have been associated with Turner's syndrome in the past, including one case only of proven iridocyclitis. Methods. In this study we report the clinical findings of three females with Turner's syndrome and uveitis followed up for a mean period of 12.6 months. Two were observed in childhood or adolescence (10 and 16 years old). Results. All the patients showed iridocyclitis, in one case complicated by the onset of papilledema and cystoid macular edema. Associated systemic diseases (psoriasis and juvenile seronegative arthritis) were diagnosed in two cases. The third patient showed positive antinuclear antibody and HLA-DR11, without any clinical or radiologic signs of arthritis. The iridocyclitis tended to become chronic with time, and this may be partially due to the endocrinologic contraindications to the use of systemic steroids. Nevertheless, the final visual acuity was ≥8/10 in all three cases. Conclusions. Iridocyclitis should be included in the list of ocular manifestations in Turner's syndrome. It may tend to become chronic and may be found especially in those patients presenting other associated autoimmune systemic disease. [ABSTRACT FROM AUTHOR]

Objective: To describe the medical treatment of severe ocular hypotony in HIV-seropositive patients with cytomegalovirus retinitis and cidofovir-associated uveitis.Patients and Methods: Two HIV-seropositive patients with cytomegalovirus retinitis and cidofovir-associated uveitis complicated by severe ocular hypotony were unresponsive to conventional therapy after treatment with cidofovir was stopped. They were subsequently treated successfully with ibopamine 2% eyedrops and dexamethasone 0.1% eyedrops.Results: In both cases, an increase in intraocular pressure to normal values was observed on average 18.5 days after starting treatment. Intraocular pressure remained stable while on therapy for a mean follow-up of 9.5 months. During the follow-up period, any attempt to stop treatment was followed by an intraocular pressure decrease; conversely, restoration of therapy increased intraocular pressure to normal values. No reactivation of cidofovir-associated uveitis or cytomegalovirus retinitis was observed during the follow-up period.Conclusions: Ibopamine 2% eyedrops in combination with dexamethasone 0.1% eyedrops is a satisfactory therapy for severe ocular hypotony in patients with cytomegalovirus retinitis and cidofovir-associated uveitis.

Background: This report describes the clinical course of choroidal neovascular membrane (CNV) in West Nile virus-associated chorioretinitis.Case Presentation: A 28-year-old Italian woman was referred to our institution because of reduced visual acuity in the left eye dating back 4 months. A diagnosis of retinal vasculitis in the right eye and chorioretinitis with CNV in the left eye was made. A complete workup for uveitis revealed positivity only for anti-West Nile virus immunoglobulin M (IgM), while immunoglobulin G (IgG) was negative. Whole-body computed tomography and nuclear magnetic resonance imaging of the brain were also negative. Therefore, the patient was treated with a combination of oral prednisone (starting dose 1 mg/kg per day) and three intravitreal injections of bevacizumab 1.25 mg/0.05 ml, 1 month apart. Fourteen days from starting corticosteroid therapy and after the first intravitreal injection, the patient experienced increased visual acuity to 0.4. Response to therapy was monitored by clinical examination, ocular coherence tomography (OCT), OCT angiography and retinal fluorescein angiography. Three months later, resolution of CNV in the left eye was achieved and no signs of retinal vasculitis were detected in the right eye, while serum IgM for West Nile virus turned negative and IgG positive.Conclusion: CNV may be a complication of West Nile virus-associated chorioretinitis, and only subclinical retinal vasculitis may also be found even in non-endemic regions.
