Both multifocal IOLs seemed to be good options for patients with intermediate-vision requirements, whereas the trifocal IOL might be better for patients with near-vision requirements. The significant perception of visual side effects indicates that patients still must be counseled about these effects before a multifocal IOL is implanted.
The aim of the study was to compare, in a randomized prospective study, the efficacy and safety of intraorbital administration of low doses of RTX versus intravenous glucocorticoids (GCs) to treat patients affected by moderately severe thyroid-associated active orbitopathy. Twenty patients with active, moderately severe TAO, whose mean age was 56.7 years±10.2 SD participated in the study. Patients were randomly selected and treated with intraorbital injections of RTX or with i.v. GCs. Disease activity and severity were assessed by the Clinical Activity Score (CAS) and the NOSPECS. Computed tomography or magnetic resonance scans were performed in all patients. In the RTX group, full blood cell count and flow cytometric analysis on peripheral blood lymphocytes were done. The patients were followed for 20 months. In both groups, CAS and NOSPECS indexes were significantly reduced (p<0.005). In particular, CAS reduction was evident since the first follow-up with both treatments. Proptosis decreased significantly only in group B and diplopia showed no significant changes during follow-up times in both groups. Neither of the treatments affected the peripheral TRab. In group A, 5 weeks after the first injection, the CD20+ peripheral lymphocytes value was nearly zero. One patient treated with rituximab progressed to severe TAO (optic neuropathy) following the second injection so the treatment was discontinued. The data confirm the therapeutic efficacy of RTX in active TAO, even in low doses and locally administered. The efficacy on the inflammatory component of the disease is comparable to that of steroids and seems to be related with the reduction of peripheral CD20+ lymphocytes. Caution should be given to an accurate patient selection.
Spectral-domain optical coherence tomography detects retinal findings, including photoreceptor inner segment/outer segment junction abnormalities that are correlated with visual acuity changes in treated patients with Irvine-Gass syndrome.
This study suggests that intralesional administration of rituximab for treating localized ocular adnexal CD20+ lymphomas could be an effective front-line therapeutic option with negligible side effects and a good response rate and duration.
ObjectiveTo compare the performance and safety in cataract surgery of two ophthalmic viscoelastic devices (OVDs), each having separate dispersive and cohesive characteristics and different concentrations.Methods and analysisIn this prospective, randomised, controlled clinical study, one eye of each patient was injected with OVD1 (Viscopack14) or OVD2 (DuoVisc) during phacoemulsification and intraocular lens implantation. Endothelial cell count, intraocular pressure (IOP), central corneal thickness (CCT), intraocular inflammation and corrected distance visual acuity (CDVA) were compared 3 months postoperatively.ResultsThe study enrolled 127 patients. Randomisation assigned 50 eyes of as many patients to each arm of the study. The postoperative mean endothelial cell loss was 14.4% and 7.1% from baseline in the OVD1 and OVD2 groups, respectively (p=0.08). The incidence of IOP spikes at 2 hours was 0% and 8%, respectively (p=0.02). There were intergroup differences in postoperative IOP values, the OVD2 group showed significantly higher values at all of the follow-up visits starting from the 24 hours examination (p<0.05). There was no statistically significant difference in the CCT, intraocular inflammation and CDVA at the end of follow-up.ConclusionBoth OVDs showed similar clinical performances and were equally effective during cataract surgery. Viscopack14 showed more corneal endothelial cell reduction, while DuoVisc had more occurrences of IOP values and spikes. Future studies are mandatory to support these preliminary results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
