Amaurosis Fugax Due To Pleomorphic Sarcoma, Sheila Pabon, Katherine Williams, Marena Patronas

Ophthalmology Faculty Publications

Purpose

This report describes a case of amaurosis fugax due to a rare primary cardiac sarcoma.

Observations

A patient who was recently diagnosed with left atrial pleomorphic sarcoma presented with a chief complaint of multiple episodes of intermittent vision loss in the right eye during the course of radiation therapy.

Conclusions and importance

The authors postulate emboli from the left atrial sarcoma entered systemic circulation and subsequently caused brief episodes of transient occlusion to retinal, ophthalmic and/or ciliary arteries leading to momentary retinal hypoxia. We believe this is a novel finding, previously unreported in the literature, of transient embolic occlusion …

Iris Abscess A Rare Presentation Of Intravenous Drug Abuse Associated, Jonathan Pierce, Nisha Warrier, Christina Antonopoulos, Nicole Siegel, Deeba Husain

Ophthalmology Faculty Publications

Purpose: To describe an unusual case of intravenous drug abuse associated endogenous endophthalmitis presenting with an iris abscess.

Observations: A 30-year old female with history of intravenous drug use presented with a two-week history of redness and blurry vision in the right eye. An initial diagnosis of anterior uveitis was made. However, she worsened on topical steroids and mydriatics. She was found to have a hypopyon and an iris abscess. She received broad spectrum antibiotic and antifungal treatment with voriconazole, this lead to significant clinical improvement. She was discharged on oral fluconazole and lost to follow up. The patient was …

OBJECTIVE: To describe baseline characteristics, initial postoperative refractive errors, operative complications, and magnitude of the intraocular lens (IOL) prediction error for refractive outcome in children undergoing lensectomy largely in North America.

DESIGN: Prospective registry study of children from birth to enrollment.

PARTICIPANTS: Total of 1266 eyes of 994 children; 49% female and 59% white.

METHODS: Measurement of refractive error, axial length, and complete ophthalmic examination.

MAIN OUTCOME MEASURES: Eye and systemic associated conditions, IOL style, refractive error, pseudophakic refraction prediction error, operative and perioperative complications.

RESULTS: Mean age at first eligible lens surgery was 4.2 years; 337 (34%) were(59%). Additional …

Stem Cell Therapy And Macular Degeneration, Brenda Stern

The Science Journal of the Lander College of Arts and Sciences

Macular degeneration is the leading cause of vision loss in Americans sixty years and older. Currently, it is an incurable disease. Stem cell therapy is the idea of transplanting stem cells to replace damaged cells in the body. As the demand for transplantable organs far outweighs the supply, stem cells are an encouraging alternative to replace damaged cells. Can stem cell therapy be the first cure for macular degeneration? Many experiments have been done on transplanting stem cells into the eyes of rats with macular degeneration yielding promising results. The first transplantation of retinal pigmented epithelial stem cells into humans …

The Role Of Sox4 In Regulating Choroid Fissure Closure And Retinal Neurogenesis, Wen Wen

Theses and Dissertations--Biology

The development of the vertebrate eye is tightly controlled by precise genetic regulations. From a single ocular primordium to bilateral eyes with complex structures and cell types, it requires intensive proliferation and migration for cells in both the ectoderm and mesoderm to accomplish ocular morphogenesis, and during this process cell differentiation and interaction takes place to establish the complex composition of ocular cell types and cellular connections. Genetic defects can lead to severe abnormalities in eye morphogenesis and cell differentiation during ocular development. A tremendous amount of work has been done to identify both intrinsic and extrinsic factors that regulate …

Assessing The Expression Of Astrocytic Markers In Retinal Ganglion Cell Projection Of Lcr/Hcr Rats, Isabella K. Bartholomew, Samuel Crish, James Holda, Jordan Renna, Gina Wilson

Williams Honors College, Honors Research Projects

Metabolic Syndrome is a human condition that presents with various metabolic issues such as abnormal distribution of body fat, high blood pressure, and a prothrombotic state, among other problems (Alberti,et al, 2005). This syndrome is a risk factor for visual disorders, such as glaucoma, and is often associated with increased levels of neuroinflammation. Currently, the animal model used to replicate this syndrome is The Low Capacity Runner and High Capacity Runner Rat Model. These rats have been bred based on their running capacities for 30+ generations to have drastic metabolic differences. We assessed key areas of the retinal ganglion cell …

Frequency Of Retinopathy Of Prematurity In A Tertiary Care Hospital, Shiyam Sunder Tikmani, Tufail Soomro, Prashant Tikmani

Community Health Sciences

Introduction: Retinopathy of prematurity (ROP) is one of a preventable cause of blindness in neonates. Screening of preterm infants for ROP in Pakistan is currently under-recognized. The aim of this study was to determine the frequency of retinopathy of prematurity (ROP) in premature and very low birth weight neonates (birth weight ≤ 1500 g and gestational age ≤ 32 weeks) in a tertiary care hospital, Karachi, Pakistan.
Methods: This was a cross-sectional study carried out in the neonatal intensive care unit (NICU) of Civil Hospital Sukkur from 1st June 2014 to 17th June 2015. Preterm neonates with birth weight ≤ …
