RESUMO
PURPOSE: To assess the performance of interferon-gamma release assay (IGRA) associated with tuberculosis skin test (TST) for ocular tuberculosis (OTB) diagnosis and therapeutic decision making. METHOD: One hundred and ninety-one patients with ocular inflammation were prospectively followed-up. Patients with clinical signs highly suspected of OTB, TST≥10 mm, and/or IGRA≥0.35 IU/mL received antitubercular therapy (ATT). Sensitivity (Se), specificity (Sp), and area under the curve (AUC) were assessed. RESULTS: Seventy-two (37.7%) patients received ATT for presumed OTB. Combining TST and IGRA had Se=89.6%, Sp=99.2%, and AUC (0.98) significantly higher compared to TST (0.85, Z=6.3, p<.001) or IGRA (0.95, Z=2.5, p=.01). Prior history of corticosteroids or immunosuppressant with concomitantly oral prednisone and baseline IGRA> 2.0 IU/mL was associated significantly with more recurrences in ATT patients (p=.01) . CONCLUSION: Considering TST and IGRA together was more effective in assessing OTB diagnosis. The real value of the IGRA test to predict recurrences needs further studies.

PURPOSE: To evaluate the clinical features and management of presumed ocular tuberculosis (OTB). METHOD: A prospective 3-year follow-up study of patients with ocular inflammation that performed Interferon-gamma release assay (IGRA) and tuberculin skin test (TST) was conducted in a tertiary referral center in Brazil. Patients with clinical signs highly suspect of OTB with a positive TST and/or IGRA with other causes ruled out were prescribed anti-tuberculosis therapy (ATT) during 9 months. Clinical features and treatment outcomes were recorded. RESULTS: Seventy-two patients (mean age 48.3 ± 15.7 years) were included in the study, and most were female (65.3%, n = 47). Posterior uveitis (43.1%, n = 31) was the main clinical feature. Multifocal choroiditis (25%, n = 18) was the most common choroidal involvement. Concomitant oral prednisone (45.8%, n = 33) during ATT was associated with more recurrences (p = 0.04). A significant difference (p < 0.001) between initial and final best-corrected visual acuity after ATT conclusion was observed. Cure or remission was observed in 58 (85.3%) patients that completed follow-up (n = 68). CONCLUSION: In our cohort some variation in demographics and ocular phenotypes of presumed OTB was observed. The high rates of cure or remission of our patients strongly support the ATT in presumed OTB. Oral corticosteroids during ATT were associated with higher recurrences rates.

PURPOSE: The purpose of this study was to analyze the evolving trends of surgical techniques and indications of corneal transplantation (CT) at a tertiary hospital in Brazil. METHODS: The medical records of all patients who underwent CT at the Hospital Oftalmológico de Sorocaba (Sorocaba Eye Hospital) from the Banco de Olhos de Sorocaba (Sorocaba Eye Bank) group in Sorocaba, Brazil, from January 1, 2012, to December 31, 2019, were analyzed. Data regarding age, sex, transplant indication, and surgical technique were collected. RESULTS: A total of 16,250 CTs were performed. There was a statistically significant decreasing trend of keratoconus-related CT ( P < 0.0001), with rates dropping from 41.7% among all CTs in 2012 to 25.5% in 2019. Penetrating keratoplasty, anterior lamellar keratoplasty, and endothelial keratoplasty (EK) accounted for 59.3%, 27.1%, and 7.8% of the CTs performed in 2012 and 33.3%, 16.4%, and 39.9% in 2019, respectively. A statistically significant decreasing trend was observed for penetrating keratoplasty ( P < 0.0001) and anterior lamellar keratoplasty ( P < 0.0001), whereas EK showed a statistically significant increasing trend during the period ( P < 0.0001). Among EKs, Descemet membrane EK increased statistically significantly from 12.8% in 2012 to 74.4% in 2019 ( P < 0.0001). CONCLUSIONS: This study shows relevant evolving trends in indications and preferred CT techniques in a tertiary hospital in Brazil.

Purpose: To describe the approach of Brazilian specialists in the diagnosis and treatment of tuberculosis-associated uveitis (TBU).Methods: Members of the Brazilian Uveitis Society received an electronic invitation to participate in an online questionnaire.Results: Of the 169 invited specialists, 78 answered the questionnaire. Specialists evaluated 5.6 patients with TBU annually. Tuberculin skin test (TST, 81%) was primarily used for diagnosis. Patients with presumed TBU should always be tested for syphilis and HIV according to 51 (88%) and 47 (81%) of respondents, respectively. Chest computed tomography (CT, 72%) was preferable to chest radiography (CXR) for diagnosis. A positive TST (81%) and CXR (60%) were the main indicators of anti-tuberculous therapy, with 34%, 39%, and 14% of specialists treating for 6, 9, and 12 months, respectively.Conclusions: TST remains the preferred method for TBU diagnosis and prompt treatment by Brazilian specialists, though there is no consensus regarding disease treatment and management.

PURPOSE: To evaluate quality of life in patients with uveitis-related to toxoplasmosis and its correlation with demographic, ocular involvement and psychosocial aspects.Methods: Data were collected through standardized interviews using a form to collect clinical and demographic data, in addition forms such as HADS, SF-12, NEI-VFQ-25 for health-related quality of life and anxiety and depression symptoms.Results: 81 patients were included with a mean age of 41.5 ± 14.5 years, females (50.6%) They were divided into three categories of best corrected visual acuity in the better seeing eye: normal (0-0.4 logMAR, 60 participants), low vision (0.48-0.9 logMAR, 9 participants) and blindness (>1 logMAR, 12 participants). The mean of VFQ-25 score was 75.5 ± 19.5 and the mean of SF-12 physical and mental components scores were 48.5 ± 7.4 and 52.4 ± 10.6 for health-related quality of life (HRQol). Anxiety symptoms were most prevalente than depression and were found in 38% of the subjects.Conclusions: Slightly more than a quarter of the sample presented impaired vision. It is associated with worsening of the quality of life since it affects mostly mental and related to the vision domains. This affects familiar, social and in addition, labor relations, since the majority of the subjects are in the economically active age group.

PURPOSE: To study the safety profile of Lutein/Zeaxanthin(L/Z)-based natural dye solutions in in vitro and in vivo models. MATERIAL AND METHODS: In vitro cytotoxicity and cellular growth experiments were carried out on ARPE-19 and human corneal epithelial (HCE) cell lines using different L/Z-based dye solutions, either alone or in association with brilliant blue (BB) or trypan blue (TB). Light and transmission electron microscopy studies were performed seven days after intravitreal injection of dye solutions in rabbits. Electroretinogram (ERG) recordings were taken at baseline and before histopathology. RESULTS: In vitro cytotoxicity assays demonstrated that the different L/Z-based solutions (from 0.3 to 2%), either alone or in association with BB (0.025%) or TB (0.04%), did not significantly alter mitochondrial activity (≤15%) in the cell lines tested. In addition, in vitro cell growth was inhibited by up to 60% depending on the dye solution, and in direct proportion to the concentration assayed. There was no evidence of structural alterations in the neurosensory retina, retinal pigment epithelium (RPE), or choriocapillaris-choroidal complex. b-Wave ERG records showed no significant differences (±15.2%) in comparison with baseline. CONCLUSIONS: L/Z-based dye solutions demonstrated a safe profile in in vitro and in vivo models, and may be a useful tool for staining intraocular structures.

Age-related macular degeneration (AMD) is considered the most common cause of blindness in the over-60 age group in developed countries. There are basically two forms of presentation: geographic (dry or atrophic) and wet (neovascular or exudative). Geographic atrophy accounts for approximately 85%-90% of ophthalmic frames and leads to a progressive degeneration of the retinal pigment epithelium and the photoreceptors. Wet AMD causes the highest percentage of central vision loss secondary to disease. This neovascular form involves an angiogenic process in which newly formed choroidal vessels invade the macular area. Today, intravitreal anti-angiogenic drugs attempt to block the angiogenic events and represent a major advance in the treatment of wet AMD. Currently, combination therapy for wet AMD includes different forms of radiation delivery. Epimacular brachytherapy (EMBT) seems to be a useful approach to be associated with current anti-vascular endothelial growth factor agents, presenting an acceptable efficacy and safety profile. However, at the present stage of research, the results of the clinical trials carried out to date are insufficient to justify extending routine use of EMBT for the treatment of wet AMD.
