Norrie disease is a rare, but devastating cause of pediatric retinal detachment, universally portending a poor visual prognosis. This paper describes successful surgical management of an infant with total retinal detachment associated with Norrie disease mutation. The infant was a full-term white male who presented with bilateral total funnel retinal detachments (RDs). He underwent genetic testing, which demonstrated single-point mutation 133 G>A transition in exon 2 of the NDP gene. The retinal detachment was managed with translimbal iridectomy, lensectomy, capsulectomy, and vitrectomy...

Although intravitreal injection of anti-vascular endothelial growth factor agents (IVA) can induce rapid regression of retinopathy of prematurity (ROP), late reactivation of the ROP can occur in the form of tractional retinal detachment (TRD) from contracted recurrent extraretinal fibrovascular proliferation. The authors report a case of bilateral TRD for recurrent ROP in a 3-year-old, which is the latest-reported reactivation to date. The authors propose that persistent avascular retina in eyes that have undergone IVA for ROP receive laser ablation to prevent late recurrences...

Adipose tissue-derived "stem cells" have been increasingly used by "stem-cell clinics" in the United States and elsewhere to treat a variety of disorders. We evaluated three patients in whom severe bilateral visual loss developed after they received intravitreal injections of autologous adipose tissue-derived "stem cells" at one such clinic in the United States. In these three patients, the last documented visual acuity on the Snellen eye chart before the injection ranged from 20/30 to 20/200. The patients' severe visual loss after the injection was associated with ocular hypertension, hemorrhagic retinopathy, vitreous hemorrhage, combined traction and rhegmatogenous retinal detachment, or lens dislocation...

PURPOSE: Innate immunity and dysregulation of inflammatory processes play a role in vascular diseases like atherosclerosis or diabetes. Nucleotide-binding domain and Leucine-rich repeat Receptor containing a Pyrin domain 3 (NLRP3) inflammasomes are pro-inflammatory signalling complexes that were found in 2002. In addition to pathogens and other extracellular threats, they can be activated by various endogenous danger signals. The purpose of this study was to find out whether NLRP3 activation occurs in patients with sight-threatening forms of diabetic retinopathy (DR)...

We describe the temporal changes observed with spectral-domain optical coherence tomography (SD-OCT) in the left eye of a 65-year-old man who developed a stage 1 macular hole secondary to vitreomacular traction (VMT). After 1 month, VMT had resolved spontaneously with a complete posterior vitreous detachment. Following VMT resolution, macular hole demonstrated progressive improvement and outer retinal disruption recovered spontaneously. This report highlights the importance of observation before any intervention for cases of stage 1 macular hole associated with VMT...

PURPOSE: Macular pathology, including macular holes (MHs), epiretinal membranes (ERMs), and macular edema, is a cause of irreversible vision loss in the setting of uveitis. Medical management involves corticosteroids, immunomodulatory medications, and biologics to control inflammation. Pars plana vitrectomy (PPV) has been suggested as a therapy for uveitis, with reports of reduced inflammation and decreased dependence on medication postoperatively. Currently, PPV is reserved for retinal detachments, vitreous opacities, and ERMs, causing vitreomacular traction...

BACKGROUND/AIMS: Patients with rhegmatogenous retinal detachment (RRD) who develop postoperative proliferative vitreoretinopathy (PVR) have been found to have higher preoperative laser flare values than patients with RRD who do not develop this complication. Measurement of laser flare has therefore been proposed as an objective, rapid and non-invasive method for identifying high-risk patients. The purpose of our study was to validate the use of preoperative flare values as a predictor of PVR risk in two additional patient cohorts, and to confirm the sensitivity and specificity of this method for identifying high-risk patients...
