Salinomycin Inhibits Proliferative Vitreoretinopathy Formation In A Mouse Model., Alison M. Heffer, Victor Wang, Richard T. Libby, Steven E. Feldon, Collynn F. Woeller, Ajay E. Kuriyan

Wills Eye Hospital Papers

Proliferative vitreoretinopathy (PVR) is a progressive disease that develops in a subset of patients who undergo surgery for retinal detachment repair, and results in significant vision loss. PVR is characterized by the migration of retinal pigment epithelial (RPE) cells into the vitreous cavity, where they undergo epithelial-to-mesenchymal transition and form contractile membranes within the vitreous and along the retina, resulting in recurrent retinal detachments. Currently, surgical intervention is the only treatment for PVR and there are no pharmacological agents that effectively inhibit or prevent PVR formation. Here, we show that a single intravitreal injection of the polyether ionophore salinomycin (SNC) …

Release And Extraction Of Retained Subfoveal Perfluorocarbon Liquid Facilitated By Subretinal Bss, Vibration, And Gravity: A Case Report., Kosuke Takahashi, Shuhei Kimura, Mio Morizane Hosokawa, Yusuke Shiode, Shinichiro Doi, Ryo Matoba, Yuki Kanzaki, Yoshihiro Yonekawa, Yuki Morizane

Wills Eye Hospital Papers

BACKGROUND: Perfluorocarbon liquid (PFCL) is an effective surgical adjuvant in performing vitrectomy for severe vitreoretinal pathologies such as proliferative vitreoretinopathy and giant retinal tears. However, subretinal retention of PFCL can occur postoperatively and retained PFCL causes severe visual disorders, particularly when PFCL was retained under the fovea. Although several procedures have been proposed for subfoveal PFCL removal, such as direct aspiration or submacular injection of balanced salt solution (BSS) to dislodge the subfoveal PFCL, the retinal damage associated with these procedures has been a major problem. Here, we report a case of subfoveal retention of PFCL for which we performed …

Wills Eye Hospital Papers

Over the past two decades, we have witnessed the increasing use of photodynamic therapy (PDT) in the field of ocular oncology. Based on a review of the literature and our own experience, we herein review the role of PDT for the management of intraocular tumors. The discussion includes two main topics. First, we discuss the application of PDT for benign tumors, including circumscribed choroidal hemangioma, choroidal osteoma, retinal astrocytoma, retinal capillary hemangioma (retinal hemangioblastoma), and retinal vasoproliferative tumor. Second, we assess the role of PDT for malignant tumors, including choroidal melanoma and choroidal metastasis.

Wills Eye Hospital Papers

BACKGROUND: Retinitis pigmentosa (RP) comprises a group of hereditary eye diseases characterized by progressive degeneration of retinal photoreceptors. It results in severe visual loss that may lead to blindness. Symptoms may become manifest during childhood or adulthood which include poor night vision (nyctalopia) and constriction of peripheral vision (visual field loss). Visual field loss is progressive and affects central vision later in the disease course. The worldwide prevalence of RP is approximately 1 in 4000, with 100,000 individuals affected in the USA. At this time, there is no proven therapy for RP.

OBJECTIVES: The objective of this review was to …

Wills Eye Hospital Papers

A 45-year-old man presented with a 3-month history of a mass located in the caruncle of his right eye. An incisional biopsy had been performed one month prior by another specialist, and the histopathology report showed basal cell carcinoma. The mass was completely excised with a 2 mm safety margin, and the large conjunctival defect was reconstructed with one sheet of amniotic membrane allograft. A histological diagnosis of pilomatrix carcinoma was established. To prevent recurrence after surgery, we added bevacizumab (25 mg/mL, 1.25 mg/mL per drop) eye drops four times per day for three months. At the one-year follow-up, the …

Myers, Md, L. J. Katz, Md, Scott Fudemberg, Md, Anand Mantravadi, Md, Natasha Kolomeyer, Md, Reza Razeghniejad, Md

Phase 1

Introduction: Uveitis is an inflammatory eye disorder which may elevate intraocular pressure (IOP), causing sight-threatening glaucoma. Treatment of refractory uveitic glaucoma involves implantation of a glaucoma drainage device (GDD). Uveitic glaucoma has been a minority diagnosis in prior studies comparing the valved Ahmed GDD and non-valved Baerveldt GDD. Here we compare the safety and efficacy of the Ahmed and Baerveldt GDD in uveitic glaucoma.

Methods: This retrospective comparative study was conducted on patients with uveitic glaucoma (≥14 years old) who underwent Ahmed or Baerveldt GDD implantation between 2006–2018 with a minimum follow-up of 3 months. Success was defined as …
