Gender Differences in Birdshot Chorioretinopathy and the White Dot Syndromes: Do They Exist?
Inflammatory conditions that affect the posterior pole are diverse. Specifically, birdshot chorioretinopathy and the white dot syndromes present with multiple white dots in the fundus. These diseases appear to affect similar age groups but there is question as to whether or not a difference exists between the genders. This review summarizes the current studies on birdshot chorioretinopathy and the white dot syndromes as they are related to gender, exploring the differences, if any, which may exist between prevalence, clinical presentation, and treatment response for these diseases. Though the specific etiology of these diseases remains unclear, future treatments may be guided as to how these diseases affect the sexes differently
Spontaneous Hyaloidal Contraction and Complex Retinal Detachment in a Patient With Von Hippel-Lindau Syndrome
The authors present an interventional case report of a patient with von Hippel-Lindau (VHL) syndrome who developed simultaneous exudative and combined tractional, rhegmatogenous, and exudative retinal detachment (RD) in the right and left eyes, respectively, following uneventful cryotherapy application of retinal capillary hemangioblastoma (RCH). After pars plana vitrectomy combined with encircling scleral buckling with radial element placement and silicone oil injection, complete retinal reattachment was achieved. The exudative RD of the fellow eye was managed initially with intense topical corticosteroid treatment and subsequent placement of a radial scleral buckle due to the presence of clinically apparent traction. Both eyes remained stable after successful surgical interventions, and long-term follow-up revealed no evidence of recurrent disease. The authors conclude that rapid worsening of vitreoretinal traction and exudation are complications that can occur after treatment of RCH in patients with VHL syndrome leading to complex retinal detachments
Ocular Pharmacology for Scleritis: Review of Treatment and a Practical Perspective.
Scleritis is defined as an infectious or noninfectious inflammation of the sclera that can be broadly categorized according to anatomic location (ie, anterior or posterior) and whether the process is necrotizing or non-necrotizing. Treatment for scleritis is dictated by the etiology of the inflammation, with infectious forms requiring treatment of the inciting agent and noninfectious forms requiring treatment of the underlying inflammation with immunosuppression. Pharmacotherapy for noninfectious scleritis can be classified according to delivery route (eg, local or systemic) and mechanism of action (eg, biologic or nonbiologic). This review will briefly summarize the classification scheme for scleritis before reviewing in depth both systemic and local pharmacotherapies that can be used to effectively treat an eye afflicted by either infectious or noninfectious scleritis. Traditional anti-inflammatory agents such as nonsteroidal anti-inflammatory drugs, steroids, and immunomodulatory therapy will be discussed, as well as newer biologic therapies such as antitumor necrosis factor alpha and anti-CD20 agents
Surgical Outcomes of Epiretinal Membranes in Patients with a History of Well-Controlled Preoperative Uveitis.
PURPOSE: To determine surgical outcomes in patients with uveitis who underwent surgery for epiretinal membrane.
DESIGN: Multicenter, interventional, retrospective, consecutive case series.
SUBJECTS: Patients with a history of controlled uveitis and concurrent visually significant epiretinal membrane.
METHODS: All eyes underwent 23-gauge pars plana vitrectomy with membrane and internal limiting membrane peeling between 2011 and 2015. Demographic data, visual acuity, slit lamp and fundoscopic examination, and optical coherence tomography were reviewed preoperatively and postoperatively.
MAIN OUTCOME MEASURES: Visual acuity, mean central foveal thickness, macular cube volume, and uveitic activity preoperatively and postoperatively at 1, 3, and 6 months.
RESULTS: Fifteen patients (17 eyes) were included. The mean follow-up duration was 23.2 months. Seventeen eyes (88.2%) received intravenous methylprednisolone and 10 eyes (58.8%) received intraocular steroids at the time of surgery. There was a significant improvement in mean central foveal thickness (517 vs. 371 microns; P = 0.01) and macular cube volume (12.1 vs. 9.4 mm
CONCLUSION: Eyes with a history of controlled uveitis have low surgical recurrence rates that are comparable with those without uveitis. Most patients do not require escalation of immunomodulatory therapy after surgery
CONGENITAL TOXOPLASMOSIS ASSOCIATED WITH TRACTIONAL RETINAL DETACHMENT.
PURPOSE: We report a case of congenital toxoplasmosis associated with retinal detachment.
METHODS: A 9-month-old white boy presented a unilateral tractional retina detachment associated with congenital toxoplasmosis retinochoroiditis.
RESULTS: The diagnosis is supported by positive IgG (\u3e400) for toxoplasmosis and intracranial calcification on magnetic resonance imaging, along with positive family history of Toxoplasma infection in the mother.
CONCLUSION: Tractional retinal detachment is an infrequent and unconventional presentation of congenital Toxoplasma infection. Inflammatory interference with normal sequence of vitreous development may explain pathogenesis of tractional retinal detachments in the setting of congenital ocular toxoplasmosis
Treatment of Inflammatory Macular Edema with Humanized Anti-CD11a Antibody Therapy
Anti-CD11a therapy, shown in animals to decrease the expression of endotoxin-induced uveitis, was successful in improving visual acuity, reducing macular thickness, and increasing the CD56bright population in uveitis patients with macular edema
Scleral Transillumination With Digital Heads-Up Display: A Novel Technique for Visualization During Vitrectomy Surgery
BACKGROUND AND OBJECTIVE: To describe a novel technique of scleral indentation and transillumination for single-surgeon, unassisted vitrectomy and vitreous base shaving enhanced with a digital heads-up display system (NGENUITY 3D Visualization System; Alcon, Fort Worth, TX).
PATIENTS AND METHODS: This technique was utilized in six eyes of six patients during vitrectomy surgery for common vitreoretinal surgical diagnoses. In each case, the transillumination was performed with the traditional intraocular light pipe set at 100% power, placed obliquely just posterior to the vitreous base insertion, with or without a transillumination adapter. The visualization of the vitreous cavity was digitally enhanced using a heads-up display system (NGENUITY 3D) with light amplification settings increased to near-maximal gain. In each case, the adequacy of the surgical view was judged intraoperatively by two independent surgeons who shared the same surgical view as the primary surgeon.
RESULTS: In this series, the surgical view provided by the scleral transillumination was deemed adequate to safely perform surgery in five of six cases. In the one patient in whom this was not the case, vitrectomy was completed using traditional endo-illumination and scleral depression performed by a skilled assistant. Lighter fundus pigmentation, myopia, thin sclera, and absence of dense peripheral media opacities were associated with improved view with scleral transillumination. There were no intraoperative complications.
CONCLUSION: Digitally enhanced scleral transillumination affords surgeons another option for safe and effective simultaneous scleral depression and illumination for unassisted peripheral vitrectomy. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:436-439.]
