Herpes Simplex Keratitis After Prk, Joshua Graf Od

Optometric Clinical Practice

Background: Herpes simplex virus (HSV) is a double stranded DNA virus that infects much of the world’s population. The World Health Organization estimates 67% of people under the age of 50 have HSV-1 and 11% of people under the age of 50 have HSV-2. While most systemic infections remain inactive and do not cause symptoms, the activation and appearance of ocular HSV can be a destructive and vision-threatening issue. HSV keratitis can be epithelial, stromal or a combination. Patients who have recently undergone photorefractive keratectomy (PRK) have a higher risk of HSV keratitis. Because of this, HSV keratitis should be …

A Reliable Diabetic Retinopathy Grading Via Transfer Learning And Ensemble Learning With Quadratic Weighted Kappa Metric, Sai Venkatesh Chilukoti, Liqun Shan, Vijay Srinivas Tida, Anthony S. Maida, Xiali Hei

Computer Science Faculty Publications

The most common eye infection in people with diabetes is diabetic retinopathy (DR). It might cause blurred vision or even total blindness. Therefore, it is essential to promote early detection to prevent or alleviate the impact of DR. However, due to the possibility that symptoms may not be noticeable in the early stages of DR, it is difficult for doctors to identify them. Therefore, numerous predictive models based on machine learning (ML) and deep learning (DL) have been developed to determine all stages of DR. However, existing DR classification models cannot classify every DR stage or use a computationally heavy …

Sagging Eye Syndrome--An Overlooked Diagnosis, Zachary Tlumak Od, Theresa Zerilli-Zavgorodni Od, Nancy Shenouda-Awad Od

Optometric Clinical Practice

Abstract

Background: Sagging Eye Syndrome (SES) is a relatively unknown cause for binocular distance diplopia. SES presents with an acquired comitant or non-comitant small angle esotropia and/or hypotropia commonly occurring in the elderly population. Inferior displacement of the lateral rectus secondary to age-related degeneration of orbital connective tissue and extraocular muscles appears to be responsible for the ocular misalignment. SES patients often present with new onset or progressively worsening distance diplopia, typically warranting neuroimaging. However, through understanding SES, eye care practitioners may identify these cases, avoiding unnecessary imaging studies. Case Report: A 90-year-old male presented with complaints of intermittent horizontal …

Autosomal Dominant Optic Atrophy Plus Syndrome, Aaron W. Case Od, Lovelee E. Sayomac Od, Matthew J. Anderson Od

Optometric Clinical Practice

Background: Dominant optic atrophy (DOA) is the most commonly encountered hereditary optic neuropathy in clinical practice and is the result of a mutation in the OPA1 or OPA3 genes encoding mitochondrial membrane proteins. The resultant mitochondrial dysfunction causes a distinct set of ophthalmic findings and may progress to extra-ocular systems known as OPA plus syndrome. We present a case of late-onset OPA plus syndrome encompassing both typical ophthalmic findings and the rarer extra-ocular findings. Case Report: A 41 year-old Caucasian male presents for a second opinion regarding a previously diagnosed traumatic optic neuropathy. Examination revealed decreased best-corrected acuities, …

Stem Cell Technology For Age Related Macular Degeneration Intervention, Laura Valdez

Research Symposium

Retinal pigmented epithelium (RPE) cells are located between the choroid and photoreceptors within the eye and are essential to provide nutrients from blood to rods and cones, as well retinoids of the visual cycle. Vision loss and various ocular diseases are attributable to the degeneration or dysfunction of the RPE cells, leading to blindness.One of the major ocular problem from RPE dysfunction is macular degeneration. Age-related macular degeneration (AMD) can be frequently diagnosed in patients over the age of 60. In the early stages of AMD, some symptoms may not be noticeable but will lead to vision loss in both …
