RESUMO

PURPOSE: To report the clinical and fluorescein angiographic (FA) features of demyelinating plaque-associated uveitis (DPU), a subset of uveitis in which patients have demyelinating plaques on the brain/cervical magnetic resonance image (MRI) but do not meet the criteria for multiple sclerosis (MS). METHODS: In this retrospective observational study, Persian Patients were diagnosed with DPU and included if (1) they never satisfied the MS criteria, (2) all other possible etiologies were excluded, and (3) they were followed for at least 2 years. RESULTS: After a median follow-up of 3 years (interquartile range, 2.0-5.3), 8 out of 40 (20%) patients diagnosed with DPU were excluded as they subsequently met the MS criteria. Of remaining 32 patients studied, the mean age was 36.3±9.9 (range 20-56 years), and 30 (93.8%) were female. Twenty-four (75.0%) showed bilateral involvement and 27 (84.4%) had insidious-chronic course. Uveitis was classified as intermediate (with or without anterior uveitis) in 29 (90.6%) and isolated anterior in 3 (9.4%) patients. Nine (28.1%) patients had at least one systemic neurological complaint. Ocular findings were: granulomatous keratic precipitates in 43/44 (97.7%) eyes; snowballs in 25/52 (48.1%) eyes; snowbanks in 4/52 (7.7%) eyes; cystoid macular edema in 20/56 (35.7%) eyes; and optic neuritis in 5/56 (8.9%) eyes. Visual acuity was ≥ 20/40 in 39 eyes (69.6%) at presentation which improved to 46 eyes (81.2%) at 2-year follow up. The two most frequent findings in FA were optic disc leakage/staining in 44/52 (81.5%) eyes, and peripheral retinal perivascular leakage in 39/52 (76.9%) eyes, which in 14/52 (26.9%) eyes extended beyond the equator. CONCLUSION: DPU usually presents as a bilateral chronic granulomatous intermediate and, less often, isolated anterior uveitis, especially in females. Most are neurologically asymptomatic. Visual outcome is generally favorable. In FA, peripheral retinal perivascular leakage is common. DPU patients have an increased tendency to develop MS and should be prohibited from anti-TNF treatment.

RESUMO

BACKGROUNDS: PCR is a proper technique that significantly improves toxoplasmosis diagnosis. However, a more sensitive technique is required. This study compared real-time PCR with nested PCR using B1, SAG-4, and MAG-1 bradyzoite genes to diagnose toxoplasmosis in toxoplasmic retinochoroiditis patients. METHODS: Blood samples were collected from 10 patients with active toxoplasmic chorioretinal lesions and 10 healthy individuals. Blood samples including peripheral blood mononuclear cells (PBMCs), serum and whole blood samples were used for DNA extraction. Serum was also used to detect anti-toxoplasma IgG and IgM antibodies. Nested PCR and real-time PCR were performed using B1, SAG-4, and MAG-1 target genes. RESULTS: Five (50%) out of the 10 patients were tested positive for toxoplasmosis with nested PCR using the PBMC samples. All the five patients tested positive with nested PCR were also tested positive for toxoplasmosis with real-time PCR using the PBMC samples. The real-time PCR results demonstrated that 9(90%) out of the 10 patients were positive based on B1 and the remaining one (10%) was positive only based on MAG-1. In general, of the patients, five (50%) were positive using SAG-4 and three (30%) were positive in term of MAG-1 using PBMCs with real-time PCR. CONCLUSION: It appears that PBMC samples have the best performance as the PCR extraction method and are a good source for toxoplasmosis diagnosis. The use of B22 and B23 target genes due to their high sensitivity and specificity along with bradyzoite genes are recommended for toxoplasmosis diagnosis using PBMC samples with real-time PCR.

RESUMO

PURPOSE: Vogt-Koyanagi-Harada (VKH) disease is a primary autoimmune granulomatous choroiditis that begins in the choroidal stroma. The aim of this review was to gather a body of evidence for the concept of a window of therapeutic opportunity, defined as a time interval following initial-onset disease during which adequate treatment will substantially modify the disease outcome and possibly even lead to cure, similar to what has been described for rheumatoid arthritis. METHODS: We reviewed the literature and consulted leading experts in VKH disease to determine the consensus for the notion of a therapeutic window of opportunity in VKH disease. RESULTS: We found a substantial body of evidence in the literature that a therapeutic window of opportunity exists for initial-onset acute uveitis associated with VKH disease. The disease outcome can be substantially improved if dual systemic steroidal and non-steroidal immunosuppressants are given within 2-3 weeks of the onset of initial VKH disease, avoiding evolution to chronic disease and development of "sunset glow fundus." Several studies additionally report series in which the disease could be cured, using such an approach. CONCLUSIONS: There is substantial evidence for a therapeutic window of opportunity in initial-onset acute VKH disease. Timely and adequate treatment led to substantial improvement of disease outcome and prevented chronic evolution and "sunset glow fundus," and very early treatment led to the cure after discontinuation of therapy in several series, likely due to the fact that the choroid is the sole origin of inflammation in VKH disease.

RESUMO

PURPOSE: To report the spectrum of Vogt-Koyanagi-Harada (VKH) disease in Persians. MATERIALS AND METHODS: This is a retrospective chart review of patients diagnosed with VKH disease at four referral centers in Iran. Patients' demographics, ocular and extraocular manifestations, treatment modalities, complications, and visual outcomes were collected and analyzed. RESULTS: Eighty-eight patients with a mean age of 32.1 ± 12.6 years (range 7-79 years) were studied. Fifty-nine patients (67.0%) were female. Sunset glow fundus was seen in 40.9%, and nummular peripheral chorioretinal scars in 55.7% of eyes. Integumentary findings were noticed in 14.8% of the patients. In patients with acute presentation, exudative retinal detachment was the most common ocular finding (87.8%) followed by optic disk swelling (71.4%). Anterior uveitis and vitritis each were found in about half of the studied eyes. Auditory symptoms were reported by 38.8% of the patients. Overall, immunomodulatory agents were used in 72.7% of the patients. Ocular complications occurred in 36.4% of eyes (mean follow-up 3.8 years, range 6-228 months). Final visual acuity was 20/40 or better in 73.3% of eyes. Four patients (4.5%) were classified as having 'complete' type of the disease, 36 (40.9%) 'incomplete' type, and 48 (54.5%) 'probable' type. CONCLUSION: In our series, there are clinical features that differ from those reported in other studies. While auditory symptoms occurred in more than one-third of patients, integumentary findings were rather rare. Most patients exhibited the 'probable' type of VKH disease. The overall visual prognosis was favorable.

RESUMO

To describe clinical features, laboratory findings, course of disease and response to treatment in four patients diagnosed with Posner-Schlossman syndrome (PSS) who had evidence of cytomegalovirus (CMV) infection in their aqueous humour. Review of four consecutive CMV positive PSS patients seen at the Noor Eye Hospital. CMV was diagnosed by polymerase chain reaction analysis of their aqueous. All four patients were immunocompetent males. Mean age of onset was 44.5 years (range, 32-63 years). Maximum intraocular pressure ranged from 36 to 48 mmHg. Mild to moderate anterior chamber reaction, lack of posterior synechiae and posterior segment involvement were consistent features in all the patients. Three patients had diffuse iris atrophy. One patient with a stromal immune ring at presentation developed features of Fuch's heterochromic iridocyclitis (FHI) later in his course of disease. Heterochromia was also observed in another patient. All patients had a positive titre of IgG but not IgM against CMV, and none had concomitant CMV antigenemia. One patient who had recalcitrant uveitis and glaucoma and another patient who was suffering from frequent attacks and showed evidence of significant endothelial cell loss received anti-CMV therapy. In our population, PSS may be associated with CMV infection and may develop clinical features similar to FHI. Anti-CMV therapy should be reserved for cases with recalcitrant course or secondary complications.

RESUMO

Our purpose is to describe blue-light fundus autofluorescence (BAF) features of inflammatory diseases of the outer retina characterised by photoreceptor damage. BAF from patients diagnosed with secondary and primary inflammatory photoreceptor damage were retrospectively analyzed and compared to other imaging modalities including fluorescein angiography (FA), indocyanine green angiography (ICGA), and spectral domain optical coherence tomography (SD-OCT). Multiple evanescent white dot syndrome (MEWDS), idiopathic multifocal choroiditis (MFC), acute posterior multifocal placoid pigment epitheliopathy (APMPPE), serpiginous choroiditis (SC), and acute syphilitic posterior placoid chorioretinitis (ASPPC), all cases corresponding to secondary photoreceptor diseases caused by inflammatory choriocapillaris nonperfusion, were included and compared to primary photoreceptor disease entities, including acute zonal occult outer retinopathy (AZOOR) and cancer-associated retinopathy (CAR). Both groups showed increased BAFs of variable intensity. In severe cases of APMPPE and ASPPC, BAF also showed hypoautofluorescent areas. In group 1 (secondary diseases) BAF hyperautofluorescent areas were associated with colocalized ICGA hypofluorescent areas, indicating choriocapillaris nonperfusion; whereas in group 2 (primary diseases), no ICGA signs were detected. The associated colocalized areas of hypofluorescence on ICGA in the first group, which were absent in the second group, were crucial to allow the differentiation between primary (photoreceptoritis) and secondary (choriocapillaritis) photoreceptor diseases. BAF patterns in inflammatory diseases of the outer retina can give relevant information on the photoreceptor and RPE involvement, with ICGA being crucial to detect concurring choriocapillaris damage and differentiating the two pathologies.

RESUMO

BACKGROUND: The global and precise follow-up of uveitis has become possible with the availability of dual fluorescein (FA) and indocyanine green angiography (ICGA) since the mid-1990s. Progressively, additional non-invasive imaging methods have emerged, bringing value-added precision to the imaging appraisal of uveitis, including, among others, optical coherence tomography (OCT), enhanced-depth imaging OCT (EDI-OCT) and blue light fundus autofluorescence (BAF). More recently, another complementary imaging method, OCT-angiography (OCT-A), further allowed retinal and choroidal circulation to be imaged without the need for dye injection. PURPOSE: The purpose of this review was aimed at examining the evidence in published reports indicating whether OCT-A could possibly replace dye angiographic methods, as well as the real practical impact of OCT-A. METHODS: A literature search in the PubMed database was performed using the terms OCT-angiography and uveitis, OCTA and uveitis and OCT-A and uveitis. Case reports were excluded. Articles were classified into technical reports, research reports and reviews. Articles in the two latter categories were analyzed in a more detailed, individual fashion. Special attention was paid to whether there were arguments in favor of an exclusive rather than complementary use of OCT-A. Furthermore, a synthesis of the main practical applications of OCT-A in the management of uveitis was attempted. RESULTS: Between 2016 (the year of the first articles) and 2022, 144 articles containing the search terms were identified. After excluding case report articles, 114 articles were retained: 4 in 2016, 17 in 2017, 14 in 2018, 21 in 2019, 14 in 2020, 18 in 2021 and 26 in 2022. Seven articles contained technical information or consensus-based terminology. Ninety-two articles could be considered as clinical research articles. Of those, only two hinted in their conclusions that OCT-A could hypothetically replace dye methods. The terms mostly used to qualify the contribution of the articles in this group were "complementary to dye methods", "adjunct", "supplementing" and other similar terms. Fifteen articles were reviews, none of which hinted that OCT-A could replace dye methods. The situations where OCT-A represented a significant practical contribution to the practical appraisal of uveitis were identified. CONCLUSION: To date, no evidence was found in the literature that OCT-A can replace the classic dye methods; however, it can complement them. Promoting the possibility that non-invasive OCT-A can substitute the invasive dye methods is deleterious, giving the elusive impression that dye methods are no longer inevitable for evaluating uveitis patients. Nevertheless, OCT-A is a precious tool in uveitis research.

RESUMO

BACKGROUND: To identify the clinical ocular signs of uveitis associated with latent tuberculosis. DESIGN: Retrospective case-control study. PARTICIPANTS: Consecutive patients from Singapore National Eye Centre Uveitis over 9 years. Sixty-two patients with uveitis associated with latent tuberculosis were compared with 72 matched controls diagnosed with other known uveitides. METHODS: Patients were categorized as: (A) predominantly anterior segment inflammation (anterior uveitides) and (B) predominantly posterior segment inflammation (intermediate, posterior or pan-uveitides). The diagnostic performance of combining these clinical signs with investigations such as interferon-gamma release assay positivity and chest X-ray results suggestive of pulmonary tuberculosis was done using area under the receiver operator characteristic curve. MAIN OUTCOME MEASURES: Sensitivity, specificity and likelihood of association with tuberculosis of various clinical signs. RESULTS: Extensive posterior synechiae and concomitant anterior scleritis in Group A; low-grade anterior chamber activity, retinal phlebitis and severe vitritis in Group B were significantly associated with latent tuberculosis. Combining these clinical signs with a positive interferon-gamma release assay and tuberculin skin test improved the diagnostic performance in both groups (area under the receiver operator characteristic curve for Group A = 0.779; Group B = 0.789). CONCLUSION: Patients with a combination of suggestive clinical signs with positive interferon-gamma release assay and tuberculin skin test are more likely to be accurately diagnosed with uveitis associated with latent tuberculosis, which responds to anti-tuberculosis therapy.

RESUMO

PURPOSE: This study aimed to evaluate biosimilar adalimumab's efficacy and safety in patients with Behçet's uveitis in Iran. METHODS: We performed a study on patients who mostly (79.2%) had a failure on conventional treatment with the mean follow-up time of 19.24 months (95% confidence interval (CI), 16.52-21.96). All the enrolled patients were anti-tumor necrosis factor (anti-TNF) naiive. The primary endpoint was best-corrected visual acuity (BCVA) improvement, and the secondary endpoints were changes in macular thickness, vitreous haze grade, anterior chamber (AC) cell grade, prednisolone dose, and the incidence of adverse reactions. RESULTS: Forty-eight patients were enrolled in the study. After adalimumab use, visual acuity improved significantly (p-value˂.001); vitreous haze grade decreased (p-value˂.001), and AC cell grade improved (p-value = .002). Macular thickness decreased, but its change was not statistically significant (p-value = .1). Moreover, adalimumab showed a corticosteroid-sparing effect (p-value = .03). CONCLUSION: Biosimilar adalimumab (CinnoRA®) is effective and well-tolerated in Behçet's uveitis.

RESUMO

PURPOSE: To describe the optical coherence tomography (OCT) findings of toxoplasmic retinochoroiditis at different stages of activity. METHODS: Observational case series. RESULTS: A total of 32 eyes of 31 patients were included; 43 sets of OCT were reviewed. A total of 14 lesions were classified as active, 13 as partially active, and 16 as inactive. All active lesions demonstrated increased retinal thickness and reflectivity with blurring of details of retinal layers. Choroidal granuloma was detected in eight (61.5%) and serous retinal detachment in nine (64%). In partially active lesions, sustained thickening and/or attachment of posterior hyaloid face with fine epiretinal membrane was the hallmark. Scarified lesions showed decreased retinal and choroidal thickness starting from the periphery. Characteristic signs for decreased activity of a lesion seen in majority of both partially active and inactive lesions were RPE changes and retina-RPE approximation. We called this unique feature 'hourglass configuration'. CONCLUSION: Features in OCT are helpful to specify and monitor the activity of toxoplasmic retinochoroiditis.

RESUMO

Vogt-Koyanagi-Harada (VKH) disease is a primary autoimmune stromal choroiditis. This review aimed to provide a novel perspective of the disease. We took into account recent developments in the understanding of the disease and crucial progress in investigational modalities of the choroid, which has led to new, simpler diagnostic criteria. We analysed recent novel notions in the literature and new diagnostic tools for VKH. We identified the following updates for VKH disease: (1) A crucial differentiation between the acute initial-onset and the chronic forms of the disease; (2) the integration of new, precise imaging methods to assess choroidal inflammation; (3) the promotion of simplified, more reliable diagnostic criteria for acute initial-onset of the disease, based on the sine qua non presence of diffuse choroiditis, detected with indocyanine green angiography (ICGA) and/or Enhanced Depth Imaging OCT (EDI-OCT); and (4) treatment optimisation through early, vigorous, sustained corticosteroid and nonsteroidal immunosuppression, as the first line of treatment for initial-onset VKH disease, and monitoring subclinical choroidal inflammation during follow-ups. Several studies have shown that most patients could discontinue treatment without an inflammation relapse. ICGA and EDI-OCT represented the methods of choice for precisely monitoring disease evolution. Simplified, precise, new diagnostic criteria allow early diagnosis of VKH. In VKH disease, inflammation exclusively originates in the choroidal stroma. Therefore, in many cases, early, sustained treatment, with dual corticosteroid and nonsteroidal immunosuppressive therapy can result in full "healing", which obviates chronic, uncontrolled, subclinical choroidal inflammation.

RESUMO

PURPOSE: To report a case of Toxoplasma retinochoroiditis that was complicated by macular infarction following intravitreal clindamycin injection. METHODS: A 32-year-old otherwise healthy woman with the diagnosis of reactivation of Toxoplasma retinochoroiditis in her right eye, underwent intravitreal clindamycin injection. Shortly after injection, the visual acuity deteriorated, and the fundus examination revealed an extensive area of macular necrosis accompanied by vascular occlusion. RESULTS: The patient was observed. Unfortunately, the condition did not improve over time and resulted in a large area of retinal atrophy. CONCLUSION: Macular infarction should be considered a rare but disastrous complication that can result in severe, irreversible visual loss.

RESUMO

PURPOSE: To report the clinical spectrum, viral etiologies, therapeutic interventions, timing of rhegmatogenous retinal detachments (RRD), and visual outcomes in acute retinal necrosis (ARN) syndrome in a series of polymerase chain reaction (PCR)-positive eyes. METHODS: From January 2010 to January 2017, consecutive patients with the clinical diagnosis of ARN and a positive aqueous viral PCR were included in this observational, retrospective study. RESULTS: Nineteen eyes found to have a clinical diagnosis of ARN, of which 18 (94.7%) had a positive viral PCR. ARN was unilateral, except in one patient. None of the fellow eyes manifested ARN during follow-up. Varicella-zoster virus (VZV) was detected in 78.0% of ARN eyes. 61.1% of eyes experienced RRD. The median time for the occurrence of RRD was 12 weeks (range: 6-25 weeks) after disease onset. No correlation was found between the etiologic viral agent (VZV vs non-VZV; p = 1.000), extent of retinitis (1-2 quadrant vs 3-4 quadrants; p = 0.326), administration of intravitreal ganciclovir (injected vs not injected; p = 0.332), application of prophylactic laser retinopexy (applied vs not applied; p = 0.326), and subsequent occurrence of RRD.At a 2-year follow-up, visual impairment (VA ⩽ 20/200) and severe visual loss (VA ⩽ light perception) were significantly higher in those complicated by RRD compared to non-RRD eyes (81.8% vs 28.6%; p = 0.047, and 45.4% vs 0.0%; p = 0.004, respectively). CONCLUSION: Aqueous PCR results are highly consistent with the clinical diagnosis of ARN. Regardless of the method of management, the rate of RRD is high and is associated with a poor visual outcome.

RESUMO

BACKGROUND: Toxoplasmic chorioretinitis may occur as a result of acquired toxoplasmosis or reactivated congenital toxoplasmosis. In this study, Toxoplasma gondii bradyzoite genes along with the B1 gene were evaluated to detect T. gondii DNA in serum and peripheral blood mononuclear cells (PBMCs) of patients with toxoplasmic chorioretinitis. METHODS: Blood samples were collected from 10 patients (7 cases of active chorioretinal lesions and 3 cases of old chorioretinal scars). The genomic DNA was extracted from the patients' serum and PBMCs and a polymerase chain reaction (PCR) assay was performed using bradyzoite genes along with B1. The subjects were also evaluated in terms of the T. gondii antibodies. RESULTS: The PCR results were positive in four of seven patients (57.1%) with active ocular toxoplasmosis lesions. In three patients (42.8%), the PCR results were positive for MAG-1 and SAG-4 and in one patient (14.3%) the PCR results were only positive for the B1 gene. The PCR results were positive only in the PBMCs, whereas they were negative in the serum samples. Two patients with positive PCR results showed high Toxoplasma immunoglobulin G (IgG) antibody titres. However, none of the patients showed positive Toxoplasma IgM antibodies. CONCLUSIONS: The PBMCs are suitable for evaluating toxoplasmic chorioretinitis. The present results showed that PCR with bradyzoite genes is useful in the diagnosis of toxoplasmic chorioretinitis in PBMCs.

RESUMO

PURPOSE: To study the seasonal variability in the occurrence of acute retinal necrosis (ARN) in a series of polymerase chain reaction (PCR)-positive patients. METHODS: Consecutive patients clinically diagnosed with ARN and a positive PCR result of aqueous humor during a seven-year period were studied retrospectively. Patients' demographics, causative viral agent(s), and the date of disease onset were extracted from medical records. RESULTS: Twenty eyes of 20 patients were enrolled; the mean age at presentation was 39.6 ± 14.4 (range, 6-62) years. Nine patients were female. The most common causative agent was varicella-zoster virus in 16 patients (80%), followed by herpes simplex virus in two patients (10%). The disease onset was in winter in 10 patients (50%), and the highest incidence was in February (five patients, 25%). The cumulative occurrence of ARN was significantly higher in the first half of the year (winter and spring) compared to the second half of the year (summer and fall) (P = 0.030). In general, seasons with a high incidence of ARN were preceded by cold seasons. CONCLUSION: In our series, we observed seasonal variability in the incidence of ARN, with the highest incidence during winter and spring. However, further epidemiologic studies in different geographical areas are required to elucidate the true seasonal nature of ARN.

RESUMO

Purpose: To compare the subclinical inflammatory response (as measured by anterior chamber flare) induced after standard (3 mW/cm2, 30 min) and accelerated (18 mW/cm2, 5 min) corneal cross-linking (CXL). Methods: In this comparative, non-randomized study, patients with progressive keratoconus who underwent standard or accelerated CXL were studied. Laser flare photometery (FM-600; Kowa, Tokyo, Japan) was used to measure anterior chamber flare preoperatively and at 1 week, 1 month, 3 months, and 6 months after the procedure. Results: Sixty eyes of 60 patients were studied; 30 eyes in each group. Mean baseline flare values were 4.15 ± 1.19 and 4.57 ± 2.17 ph/ms in standard and accelerated groups, respectively (p = 0.228).and after surgery increased in all follow-up measurements in the both groups similarly (P > 0.05). Conclusion: Both standard and accelerated CXL results in induction of a subclinical inflammatory response that persists up to 6 month. The response was similar between the two groups.

RESUMO

PURPOSE: To review the clinical features, diagnosis, treatment modalities, and prognosis of Bartonella-associated neuroretinitis. METHODS: This is a narrative review on Bartonella-associated neuroretinitis including general and ophthalmological aspects of the disease. A comprehensive literature review between January 1950 and September 2018 was conducted in PubMed database. Epidemiology, clinical features, diagnosis, treatment, and prognosis of Bartonella neuroretinitis were reviewed. RESULTS: Cat scratch disease (CSD) is a worldwide distributed systemic infectious disease caused by a bacterium, Bartonella henselae (B. henselae) which is usually transmitted to humans through contact with infected cats. Ocular manifestations of CSD are diverse, with neuroretinitis and superficial retinal infiltrates being the most common and typical manifestations. Neuroretinitis typically presents as optic disc edema with a partial or complete macular star in association with mild vitritis. Macular star may be absent at the initial presentation, becoming evident 1-2 weeks after the onset of optic disc edema. Diagnosis of CSD is confirmed by reliable laboratory tests. Neuroretinitis usually has a self-limited course. Antibiotic therapy is required for severe systemic disease and vision-threatening ocular involvement. The adjunctive use of oral corticosteroids may further improve the visual outcome. CONCLUSIONS: The diagnosis of Bartonella-associated neuroretinitis is based on typical clinical findings and positive serology. The prognosis is usually favorable in immunocompetent individuals.

RESUMO

PURPOSE: To compare chronic subclinical inflammation induced after implantation of Artisan vs. Artiflex phakic intraocular lenses (pIOLs). METHODS: This prospective, comparative, non-randomized study included consecutive patients with moderate to high myopia who underwent Artisan or Artiflex pIOL implantation with standard surgery and postoperative care. Anterior chamber flare was assessed quantitatively using laser flare photometry (LFP) at baseline, 1 week, 1 month, 3 months, 6 months, and 2 years after surgery. RESULTS: PIOLs were implanted in 72 eyes (40 patients); Artisan pIOLs in 16 eyes (Artisan group) and Artiflex pIOLs in 56 eyes (Artiflex group). The mean preoperative anterior chamber flare was 6.5 ± 2.3 (range, 4.2-9.5) photons per millisecond (ph/ms) and 4.2 ± 0.9 (range, 2.5-11.7) ph/ms in Artisan and Artiflex groups, respectively (P = 0.400). In spite of early postoperative rise, the flare value returned to preoperative levels 6 months after pIOL implantation and remained stable up to 2 years. The amount of flare was not statistically different between Artisan and Artiflex groups in any postoperative follow-up (all P > 0.05). The trend in flare changes was not different between the studied groups (ANCOVA, P = 0.815). CONCLUSION: The inflammatory response induced by implantation of either type of Artisan and Artiflex pIOLs is short-lived without statistically significant difference between the two models.

RESUMO

PURPOSE: To report the efficacy of mycophenolate mofetil (MMF) as adjunctive therapy for the treatment of multiple sclerosis (MS)-associated uveitis. METHODS: In this retrospective, interventional case series, patients with MS-associated uveitis who were treated by MMF as an adjunct therapy to systemic corticosteroid were studied. Patients' demographics, clinical course, response to treatment, and complications were assessed. RESULTS: A total of 30 eyes of 15 patients with a mean age of 34.5 ± 8.3 years were studied. In three patients (20%), onset of uveitis preceded the diagnosis of MS. The course of MS was relapsing-remitting in 11 patients (73.3%) and secondary progressive in four patients (26.7%). At 1 year after institution of MMF, all the patients were on oral prednisolone ≤ 7.5 mg/day, all eyes were quiet without macular edema, and 53.3% of eyes gained visual improvement. Supplemental periocular and intraocular injections were needed during the first 6 months after starting MMF therapy. The systemic adverse effects were transient and minor in severity. CONCLUSIONS: MMF had beneficial effects on vision and intraocular inflammation with an acceptable safety profile.
