Silicone oil tamponade was demonstrated to be a feasible option in conjunction with 23-g transconjunctival sutureless vitrectomy to treat complex retinal detachment.
<b><i>Background:</i></b> First-line treatment for diabetic macular edema (DME) is usually with antivascular endothelial growth factor agents, followed by intravitreal corticosteroids as a second-line treatment option. Long-term corticosteroids may offer quality of life and effectiveness benefits over short-term implants. <b><i>Objectives:</i></b> To evaluate outcomes of patients with persistent or recurrent DME who switched from a short-term (dexamethasone) to a long-term (fluocinolone acetonide, FAc) corticosteroid intravitreal implant in a real-world setting. <b><i>Methods:</i></b> This is a retrospective study in 9 Portuguese centers. An FAc intravitreal implant was administered according to product labeling. Effectiveness outcomes were mean change in visual acuity (VA; ETDRS letters), central retinal thickness (CRT; µm), and macular volume (MV; mm<sup>3</sup>). The safety outcome was mean change in intraocular pressure (IOP; mm Hg). All were analyzed at months 1 and 3, and then quarterly until month 24 after implantation. <b><i>Results:</i></b> Forty-four eyes from 36 patients were analyzed. Mean duration of DME was 3.3 ± 1.9 years, and mean follow-up was 8 months. From baseline following FAc implantation, VA increased significantly at months 1 and 6 (mean +6.82 and +13.02 letters, respectively; <i>p</i> = 0.005), and last observation carried forward (LOCF; mean +8.3 letters; <i>p</i> = 0.002). CRT improved significantly at months 1 and 6 (mean –71.81 and –170.77 µm, respectively; <i>p</i> = 0.001), and LOCF (mean –121.46 µm; <i>p</i> = 0.001). MV was consistently, but not significantly, decreased from baseline to LOCF (mean –0.69 mm<sup>3</sup>; <i>p</i> = 0.062). The mean change in IOP was –0.25 and +0.88 mm Hg at months 1 and 6, respectively (<i>p</i> = 0.268), and +1.86 mm Hg at LOCF (<i>p</i> = 0.036). Increases were controlled with topical medication in most cases. <b><i>Conclusions:</i></b> The FAc intravitreal implant is effective in patients previously treated with short-term corticosteroid implants. Thus, after a suboptimal response to antiangiogenics or a short-term corticosteroid, a single FAc implant may be considered an effective and tolerable treatment that can improve long-term outcomes for patients with sight-threatening DME.
Pupil abnormalities in leprosy usually result from chronic iritis with loss of stroma, iris miosis, a sluggish reaction to light, and poor dilation in response to anticholinergic mydriatics. We report two patients with long-standing lepromatous leprosy who developed tonic pupils characterized by mydriasis, absence of reaction to light and hypersensitivity to weak cholinergic solution. Examination revealed iritis and iris atrophy. In both cases, instillation of dilute 0.1% pilocarpine caused miosis in the affected eyes. Tonic pupil occurs in many conditions, but its association with leprosy had not been previously reported.
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.
