The study aim was to evaluate the efficacy of adalimumab (ADA) in a large series of Behçet's disease (BD)-related uveitis. We performed a multicenter retrospective observational study including 40 selected patients (66 eyes) receiving ADA. Clinical data were retrospectively analyzed at baseline, at 3 and 12 months of treatment. Primary end point was reduction of ocular inflammatory flares. Secondary end points were improvement of best corrected visual acuity (BCVA), reduction of macular thickness measured by optical coherence tomography (OCT), reduction in the occurrence of vasculitis assessed by fluorescein angiography (FA), and evaluation of statistically significant differences between patients treated with ADA monotherapy and those undergoing ADA plus DMARDs and in patients firstly treated with ADA compared to patients previously administered with other biologics; ADA steroid sparing effect was also evaluated. During the first 12 months of ADA therapy, the number of flares significantly decreased from 200 flares/100 patients/year to 8.5 flares/100 patients/year (p < 0.0001). Similarly, BCVA improved if compared to baseline (7.4 ± 2.9 versus 8.5 ± 2.1, p = 0.03). OCT findings significantly improved showing a mean reduction of central macular thickness (CMT) of 27.27 ± 42.8 μm at the end of follow-up (p < 0.006). FA identified retinal vasculitis in 22 cases at baseline (55%), 8 (20%) cases after 3 months, and in only one (2.5%) case at 12-month follow-up. FA improvement was highly significant at 3- and 12-month follow-up if compared to baseline (p < 0.0001 and p = 0.006, respectively). ADA is highly effective and safe for the treatment of BD-related uveitis, providing a long-term control of ocular inflammation.
Despite remarkable advances in vitreoretinal surgery, proliferative vitreoretinopathy (PVR) remains a common cause of severe visual loss or blindness. One of the critical reasons for PVR-induced blindness is tractional retinal detachment due to the formation of contractile preretinal fibrous membranes. This membrane formation is characterized by the proliferation and migration of cells and the excessive synthesis and deposition of extracellular matrix proteins. Herein we present the disease pathways of PVR, reviewing the role of both systemic and intraocular cells as well as molecular mediators. A chronological sequence of events leading to PVR is also hypothesized. Better understanding of the pathogenesis of PVR is needed in order to improve disease management. Efforts should be oriented towards greater cooperation between basic researchers and clinicians, aimed at matching the different clinical scenarios with the biological markers of the disease.
PURPOSE: To assess 3-year safety and efficacy of enhanced-fluence pulsed-light iontophoresis cross-linking (EF I-CXL) in patients with progressive keratoconus. METHODS: This prospective interventional pilot study included 24 eyes of 20 patients, with a mean age of 23.9 years (range: 15 to 36 years). Iontophoresis with riboflavin solution was used for stromal imbibition. The treatment energy was optimized at 30% (7 J/cm 2 ) and ultraviolet-A power set at 18 mW/cm 2 × 6.28 minutes of pulsed-light on-off exposure, with a total irradiation time of 12.56 minutes. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), corneal tomography, and corneal optical coherence tomography (OCT) at baseline and 1, 3, 6, 12, 24, and 3 years postoperatively were evaluated. RESULTS: At 3 years, average UDVA decreased from 0.50 ± 0.10 to 0.36 ± 0.08 logMAR ( P < .05), average maximum keratometry decreased from 52.94 ± 1.34 to 51.4 ± 1.49 diopters (D) (Delta: −1.40 ± 0.80 D; P < .05), average coma improved from 0.24 ± 0.05 to 0.12 ± 0.02 µm ( P = .001), and symmetry index decreased from 4.22 ± 1.01 to 3.53 ± 0.90 D. Corneal OCT showed demarcation line detection at 285.8 ± 20.2 µm average depth in more than 80% at 1 month postoperatively. CONCLUSIONS: The 3-year results of EF I-CXL showed satisfactory I-CXL functional outcomes, increasing the visibility and the depth of demarcation line closer to epithelium-off standard CXL.

A few studies have reported the safety profile of interleukin (IL)-1 blockers from real life. The aim of this study is to describe anakinra (ANA) and canakinumab (CAN) safety profile in children and adults, based on data from a real-life setting. Demographic, clinical, and therapeutic data from patients treated with ANA and CAN were retrospectively collected and analyzed. Four hundred and seventy five patients were enrolled; ANA and CAN were prescribed in 421 and 105 treatment courses, respectively. During a mean follow-up of 24.39 ± 27.04 months, 89 adverse events (AE) were recorded; 13 (14.61%) were classified as serious AE (sAE). The overall estimated rate of AE and sAE was 8.4 per 100 patients/year. Safety concerns were more frequent among patients aged ≥ 65 years compared with patients < 16 years (p = 0.002). No differences were detected in the frequency of safety concerns between monotherapy and combination therapy with immunosuppressants (p = 0.055), but a significant difference was observed when injection site reactions were excluded from AE (p = 0.01). No differences were identified in relation to gender (p = 0.462), different lines of biologic therapy (p = 0.775), and different dosages (p = 0.70 ANA; p = 0.39 CAN). The overall drug retention rate was significantly different according to the occurrence of safety concerns (p value < 0.0001); distinguishing between ANA and CAN, significance was maintained only for ANA (p < 0.0001 ANA; p > 0.05 CAN). Treatment duration was the only variable associated with onset of AE (OR = 0.399 [C.I. 0.250-0.638], p = 0.0001). ANA and CAN have shown an excellent safety profile; the risk for AE and sAE tends to decrease over time from the start of IL-1 inhibition.
This study aimed to evaluate the role of interleukin (IL)-1 inhibitors anakinra (ANA) and canakinumab (CAN) in the treatment of Behçet's disease (BD)-related uveitis. Multicenter retrospective observational study includes 19 consecutive BD patients (31 affected eyes) received treatment with anti-IL-1 agents. Data were analyzed at baseline and at 3 and 12 months. The primary endpoint is the reduction of ocular inflammatory flares (OIF). The secondary endpoints are improvement of best corrected visual acuity (BCVA); reduction of macular thickness defined by optical coherence tomography (OCT) and of vasculitis identified with fluorescein angiography (FA); evaluation of statistically significant differences between patients treated with IL-1 inhibitors as monotherapy, subjects also administered with disease modifying anti-rheumatic drugs (DMARDs) and/or corticosteroids as well as between patients administered with IL-1 inhibitors as first line biologic treatment and those previously treated with TNF-α inhibitors. At 12 months, OIF significantly decreased from 200 episodes/100 patients/year to 48.87 episodes/100 patients/year (p < 0.0001). The frequency of retinal vasculitis identified by FA significantly decreased between baseline and 3- and 12-month follow-up visits (p < 0.0001 and p = 0.001, respectively). OIF rate was significantly higher in patients co-administered with DMARDs (81.8 episodes/100 patients/year) than in patients undergoing IL-1 inhibitors as monotherapy (0.0 episodes/100 patients/year) (p = 0.03). No differences were identified on the basis of corticosteroid use and between patients administered with IL-1 inhibitors as first line biologic approach or second line. Steroid dosage was significantly decreased at 12-month visit compared to baseline (p = 0.02). Treatment with IL-1 inhibitors is effective in the management of BD-related uveitis and provides a long-term control of ocular inflammation in refractory and long-lasting cases.
A 48-year-old man presented with hyphema, iridocyclitis, iridophacodonesis, and maculopathy after a contusive trauma. Ultrasound biomicroscopy identified a 90-degree cyclodialysis cleft with severe damage of the zonular fibers. Echographic B-scan examination revealed intravitreal hemorrhage and a 360-degree choroidal detachment. One month later, phacoemulsification was performed and a single-piece poly(methyl methacrylate) intraocular lens was inserted into the ciliary sulcus, with the haptic rotated toward the cyclodialysis cleft area. Postoperatively, the visual acuity improved and the intraocular pressure returned to normal. Ultrasound biomicroscopy showed closure of the cleft by reattachment of the ciliary body to the scleral spur. Optical coherence tomography revealed complete resolution of the macular and choroidal folds. Ultrasound biomicroscopy is a useful method for appropriate management of traumatic cyclodialysis cleft. In cases of small cyclodialysis clefts, with the surgical method we describe, the lens haptics apply directional force toward the sclera, fostering adherence of the ciliary body fibers.
