Purpose: This study aimed to evaluate the utility of a rationally engineered antibody that directly blocks collagen fibrillogenesis to reduce scar tissue formation associated with subconjunctival glaucoma surgery.
Material and methods: Fourteen eyes of 7 adult rabbits underwent glaucoma filtering surgery using XEN 45 Gel Stent. The rabbits’ eyes were divided randomly into three treatment groups: (i) treated with the antibody, (ii) treated with mitomycin C, and (iii) treated with the antibody and mitomycin C. Following surgeries, the intraocular pressure and bleb appearance were evaluated in vivo. The rabbits were sacrificed 8 weeks after the surgery, and their eyes were …

Purpose: To report a patient with conjunctival and buccal neuromas and enlarged corneal nerves without Multiple Endocrine Neoplasia 2B (MEN2B).
Observations: A 28-year-old female presented with progressively enlarging bilateral limbal conjunctival growths. Slit lamp examination was notable for enlarged corneal nerves and well-circumscribed gelatinous subepithelial limbal nodules. Systemic examination revealed similar lesions on the tongue. Conjunctival biopsy demonstrated a mucosal neuroma. The patient underwent endocrine workup for MEN2B and genetic testing for the RET-proto oncogene mutations, all of which were negative.
Conclusions and Importance: The findings in our patient may be compatible with pure mucosal neuroma syndrome. The pattern of …

Dry eye disease is among the most prevalent diseases affecting the ocular surface. Artificial tears remain the cornerstone therapy for its management. There are currently a wide variety of marketed artificial tears available to choose from. These artificial tears differ significantly in their composition and formulation. This article reviews the physicochemical and biological properties of artificial tear components and how these characteristics determine their use and efficacy in the management of dry eye. Furthermore, this article also discusses the various formulations of artificial tears such as macro and nanoemulsion and the type of preservatives present in them.

Background: Post-stroke visual impairment (VI) is a common but under-recognized care challenge. Common manifestations of post-stroke VI include: diplopia, homonymous hemianopia, oscillopsia secondary to nystagmus, and visual inattention or neglect. In acute care settings, post-stroke VI recognition and treatment are often sub-optimal as emphasis is placed on survival. Stroke survivors with VI often face inconsistencies when accessing care out of hospital because variable availability and subsidization of visual rehabilitation. We sought to identify gaps in care experienced by stroke survivors with VI from stroke survivors' and care providers' perspectives.
Methods: We conducted a qualitative description study across 12 care sites …
Examining The Effects Of Hyperglycemia On Retinal Regeneration, 2023 University of Kentucky
Examining The Effects Of Hyperglycemia On Retinal Regeneration, Emmanuella Ec Kyllians
Theses and Dissertations--Biology
Diabetes is a disease that affects how the body processes glucose, leading to a cascade of other complications, one of which is diabetic retinopathy (DR). DR is a neurovascular disease that affects the retina and research has revealed the role of retinal neurodegeneration in its development. Animal models like zebrafish have emerged as important tools for studying the molecular and cellular mechanisms underlying DR. On the other hand, retinitis pigmentosa (RP) is a degenerative disease that involves the progressive degeneration of rods and cones, and hyperglycemia has been found to impair regeneration. Therefore, this study aims to examine the effects …

School of Medicine Publications and Presentations
Diabetic retinopathy (DR) is the leading cause of blindness in the working-age population. It works by disrupting the neural and vascular components in the retina and leads to loss of neural interaction/function, vascular permeability, and angiogenesis. It can be classified into two general stages: non-proliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR). DR can also lead to vascular leakage and cause diabetic macular edema (DME), the most common cause of vision loss in DR (Duh, Sun et al. 2017). There are currently a wide range of therapies, but they are limited in their efficacy and side effects. None of …

Background: To establish the proportion of patients with retinitis pigmentosa (RP) meeting the Australian fitness to drive (FTD) visual standards. Methodology: A prospective consecutive case series of patients with a clinical or genetic diagnosis of RP. Data on age at symptom onset, current driving status, inheritance pattern, better eye visual acuity (BEVA), binocular Esterman visual field (BEVF) parameters, genotype and ability to meet the driving standards based on BEVA and BEVF were collected. Outcome measures included the proportion of RP patients overall meeting the standards and clinical predictors for passing. A sub-analysis was performed on those RP patients who reported …

Research outputs 2022 to 2026
Purpose: The purpose of this study was to estimate the incidence and mortality of conjunctival melanoma in Australia from 1982 to 2014. Methods: De-identified unit data for all cases of ocular melanoma were extracted from the Australian Cancer Database from 1982 to 2014. Conjunctival melanoma cases were extracted, and the incidence and mortality were analyzed. Incidence rates were age-standardized against the 2001 Australian Standard Population. Mortality was assessed using log-rank and Cox regression. Results: From 1982 to 2014, there were 299 cases of conjunctival melanoma. The age-standardized incidence rate was 0.48 (95% confidence interval [CI] = 0.41 to 0.54) per …
High Energy Blue Light Induces Oxidative Stress And Retinal Cell Apoptosis, 2023 Arcadia University
High Energy Blue Light Induces Oxidative Stress And Retinal Cell Apoptosis, Jessica Malinsky
Capstone Showcase
Blue light (BL) is a high energy, short wavelength spanning 400 to 500 nm. Found in technological and environmental forms, BL has been shown to induce photochemical damage of the retina by reactive oxygen species (ROS) production. Excess ROS leads to oxidative stress, which disrupts retinal mitochondrial structure and function. As mitochondria amply occupy photoreceptors, they also contribute to oxidative stress due to their selectively significant absorption of BL at 400 to 500 nm. ROS generation that induces oxidative stress subsequently promotes retinal mitochondrial apoptosis. BL filtering and preventative mechanisms have been suggested to improve or repair BL-induced retinal damage, …

Background: Dermatosis papulosa nigra (DPN) affects sun-exposed areas such as the face, neck, and trunk. The prevalence of pterygium and myopia in DPN patients in Ghana has not been studied. In this study, we examined the risk and protective factors for pterygium and myopia in DPN patients. Materials and Methods: The study involved 100 participants with facial DPN. A standard ophthalmic exam was performed using a portable slit lamp and a 3.5 X magnified loop. Participants completed a closed-ended questionnaire. Logistic regression was used to summarize the level of association between DPN, myopia, and pterygium, as well as demographic factors …
