Immunosuppressive drugs; Response to therapyMedicaments immunosupressors; Resposta al tractamentMedicamentos inmunosupresores; Respuesta al tratamientoIntroduction To identify factors affecting the response rate to immunosuppressive drugs (ISDs) in patients with non-infectious uveitis (NIU). Methods This longitudinal retrospective cohort study included patients from the Hospital Clinico San Carlos Uveitis Clinic diagnosed with NIU from 1992 to 2016. Subjects were followed up from ISD prescription until the achievement of good therapeutic response (GTR), ISD treatment change, or up to 12 months. GTR was defined as the complete resolution of the eye inflammatory manifestations with a corticosteroid dose ≤ 10 or ≤ 5 mg per day of prednisone or equivalent (GTR10 and GTR5, respectively) maintained for at least 28 days. Kaplan–Meier curves were estimated for GTR. Demographic, clinical, and treatment-related factors were analyzed using Cox robust regression. Results A total of 73 patients (100 episodes of ISD prescription) were analyzed. In 44 and 41 episodes, GTR10 and GTR5 were achieved, respectively. A lower hazard for both GTRs was associated with uveitic macular edema at prescription and with a higher “highest oral corticosteroid dose prescribed in the year before ISD prescription”. GTR10 was higher if cyclosporine was prescribed (compared to other ISDs), and if a higher number of ISDs had been previously prescribed. GTR5 hazard was lower for patients with posterior uveitis or if the ISDs were prescribed before 2008, and higher if periocular corticosteroids had been administered before ISD prescription, or if the duration of the posterior segment activity was shorter. Conclusions Factors associated with GTR to ISDs may help to identify patients with NIUs who could benefit from a thorough follow-up.This work was supported by the Instituto de Salud Carlos III, Ministry of Health, Madrid, Spain [ICI19/00020; PI20/01221; RD21/002/0001].

Comparing in-vivo confocal microscopy and ex-vivo light and scanning electron microscopy images of the hairs of the pine processionary caterpillar embedded in the cornea: Report of three cases

This report describes three cases of pine processionary caterpillar hairs (setae) embedded in the cornea: one in a 69‑year‑old man with acute keratouveitis, a second case in a 65‑year‑old man with an epithelial defect and a stromal infiltrate, and the third case affecting a 54‑year‑old woman with mild keratitis. The two first patients had one hair embedded in the anterior corneal layers while the last one had several hairs deeply embedded in the stroma. By comparing in‑vivo confocal microscopy (IVCM) with ex‑vivo light microscopy (LM) and scanning electron microscopy (SEM) images, the morphology of the setae was identified and confirmed.post-print2,18 M

Glaukos iStent inject® Trabecular Micro-Bypass Implantation Associated with Cataract Surgery in Patients with Coexisting Cataract and Open-Angle Glaucoma or Ocular Hypertension: A Long-Term Study

Purpose. To evaluate the long-term efficacy and safety of the iStent inject device (Glaukos Corporation, Laguna Hills, CA) combined with phacoemulsification in patients with coexistent cataract and open-angle glaucoma or ocular hypertension (OHT). Methods. A prospective, uncontrolled, nonrandomized, interventional case series study was conducted in patients with both mild or moderate open-angle glaucoma or OHT and cataract. Patients underwent cataract surgery along with the implant of two iStent inject devices. Outcome measures were intraocular pressure (IOP), topical hypotensive medications required, and best-corrected visual acuity (BCVA). Results. 20 patients were enrolled. Mean follow-up was months. Mean baseline IOP was  mmHg with medication and  mmHg after washout. Mean end-follow-up IOP was  mmHg, representing an IOP decrease of 36.92%,  mmHg (), from baseline washout IOP. The mean number of medications was significantly reduced from to (). 45% of patients were medication-free by the end of follow-up. Mean BCVA improved significantly from to (). No complications of surgery were observed. Conclusion. The iStent inject device combined with cataract surgery served to significantly reduce both IOP and medication use in the long term in patients with coexistent open-angle glaucoma or ocular hypertension (OHT) and cataract

Agreement and clinical comparison between a new swept-source optical coherence tomography-based optical biometer and an optical low-coherence reflectometry biometer

Purpose To compare measurements taken using a swept-source optical coherence tomography-based optical biometer (IOLmaster 700) and an optical low-coherence reflectometry biometer (Lenstar 900), and to determine the clinical impacts of differences in their measurements on intraocular lens (IOL) power predictions. Methods Eighty eyes of 80 patients scheduled to undergo cataract surgery were examined with both biometers. The measurements made using each device were axial length (AL), central corneal thickness (CCT), aqueous depth (AQD), lens thickness (LT), mean keratometry (MK), white-to-white distance (WTW), and pupil diameter (PD). Holladay 2 and SRK/T formulas were used to calculate IOL power. Differences in measurement between the two biometers were determined using the paired t-test. Agreement was assessed through intraclass correlation coefficients (ICC) and Bland–Altman plots. Results Mean patient age was 76.3±6.8 years (range 59–89). Using the Lenstar, AL and PD could not be measured in 12.5 and 5.25% of eyes, respectively, while IOLMaster 700 took all measurements in all eyes. The variables CCT, AQD, LT, and MK varied significantly between the two biometers. According to ICCs, correlation between measurements made with both devices was excellent except for WTW and PD. Using the SRK/T formula, IOL power prediction based on the data from the two devices were statistically different, but differences were not clinically significant. Conclusions No clinically relevant differences were detected between the biometers in terms of their measurements and IOL power predictions. Using the IOLMaster 700, it was easier to obtain biometric measurements in eyes with less transparent ocular media or longer AL

Effect of pharmacological pupil dilation on measurements and iol power calculation made using the new swept-source optical coherence tomography-based optical biometer

Purpose: to determine whether pupil dilation affects biometric measurements and intraocular lens (IOL) power calculation made using the new swept-source optical coherence tomography-based optical biometer (IOLMaster 700©; Carl Zeiss Meditec, Jena, Germany). Procedures: eighty-one eyes of 81 patients evaluated for cataract surgery were prospectively examined using the IOLMaster 700© before and after pupil dilation with tropicamide 1%. The measurements made were: axial length (AL), central corneal thickness (CCT), aqueous chamber depth (ACD), lens thickness (LT), mean keratometry (MK), white-to-white distance (WTW) and pupil diameter (PD). Holladay II and SRK/T formulas were used to calculate IOL power. Agreement between measurement modes (with and without dilation) was assessed through intraclass correlation coefficients (ICC) and Bland-Altman plots. Results: mean patient age was 75.17 ± 7.54 years (range: 57–92). Of the variables determined, CCT, ACD, LT and WTW varied significantly according to pupil dilation. Excellent intraobserver correlation was observed between measurements made before and after pupil dilation. Mean IOL power calculation using the Holladay 2 and SRK/T formulas were unmodified by pupil dilation. Conclusions: the use of pupil dilation produces statistical yet not clinically significant differences in some IOLMaster 700© measurements. However, it does not affect mean IOL power calculation

Tear cytokine profile of glaucoma patients treated with preservative-free or preserved latanoprost

Purpose: To determine variations in cytokine levels of glaucoma patients treated either with preservative-free latanoprost or preserved latanoprost, relative to healthy individuals. Methods: Tear samples were collected from 39 healthy subjects, 20 glaucoma patients treated with preserved latanoprost, and 20 patients treated with preservative-free latanoprost. A set of 27 inflammatory cytokines was analyzed in each group, including interleukin (IL)-1β, IL-1ra, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL9, IL-10, IL-12 (p70), IL-13, IL-15, IL-17, eotaxin, fibroblast growth factor (FGF) basic, granulocyte colony stimulating factor (G-CSF), granulocyte monocyte colony stimulating factor (GM-CSF), interferon (IFN)-γ, interferon gamma-induced protein (IP)-10, monocyte chemo attractant protein (MCP)-1MCAF, macrophage inflammatory protein (MIP)-1α, MIP-1β, platelet-derived growth factor (PDGF)-BB, regulated on activation, normal T cell expressed and secreted (RANTES), tumor necrosis factor (TNF)-α and vascular endothelial growth factor (VEGF). Cytokine concentrations were obtained by the Bio-Plex Human Cytokine Immunoassay. Non-invasive tear breakup time (NI-TBUT), tear meniscus height, corneal fluorescein staining, conjunctival hyperemia and ocular surface disease index (OSDI) were assessed in patients treated with preservative-free and preserved latanoprost. Results: The levels of IL-2, IL-5, IL-10, IL-12 (p70), IL-13, IL-15, IL-17, FGF basic, PDGF-BB, and TNF-α were significantly higher in patients receiving preserved latanoprost, compared to normal controls (p 0.05). Ocular surface parameters were not significantly different in both glaucoma groups, and no correlation between these clinical parameters and cytokine levels was observed. Conclusions: Treatment with preserved latanoprost has a direct impact on tear cytokine levels, whereas this effect is not observed upon preservative-free latanoprost instillation

Novel Insights into the Transmission of SARS-CoV-2 Through the Ocular Surface and its Detection in Tears and Conjunctival Secretions: A Review

SARS-CoV-2 is a highly transmissible virus that spreads mainly via person-to-person contact through respiratory droplets, or through contact with contaminated objects or surfaces from an infected person. At present we are passing through a phase of slow and painful understanding of the origin, epidemiological profile, clinical spectrum, and risk profile of the virus. To the best of our knowledge there is only limited and contradictory evidence concerning SARS-CoV-2 transmission through other routes. Importantly, the eye may constitute not only a potential site of virus replication but also an alternative transmission route of the virus from the ocular surface to the respiratory and gastrointestinal tract. It is therefore imperative to gain a better insight into the potential ophthalmological transmission route of the virus and establish directions on best practice and future models of care for ophthalmological patients. This review article critically evaluates available evidence on the ophthalmological mode of viral transmission and the value of earlier identification of the virus on the eye. More evidence is urgently needed to better evaluate the need for protective measures and reliable ocular diagnostic tests to diminish further pandemic spread
