School of Medicine Publications

Recreational inhalation of alkyl nitrites (“poppers”) is associated with a characteristic toxic maculopathy presumably due to ischemic changes in the central macula. Alkyl nitrite candles are available for purchase online and do not appear to be regulated. We report a unique retrospective case of vision loss following second-hand inhalation of vapor from a “poppers” candle in which a 29-year-old Hispanic male with no previous medical history presented with acute bilateral vision loss after attending a party at a nightclub. The patient denied sungazing, exposure to lasers, and a family history of inherited retinal disease. History was significant for use of …

Implementation Of Artificial Intelligence In Retinoblastoma Diagnosis, Zana Moldavsky

inSIGHT

The retina is essential for vision. It is composed of 10 distinct layers and contains specialized photoreceptor cells, rods, and cones that are responsible for converting photons of light into electrical signals through a process called phototransduction.¹ These electrical signals are transmitted to the brain via the optic nerve where they are interpreted as a visual picture.¹

Retinoblastoma is a rare but aggressive malignant tumor of the retina and represents the most common intraocular malignancy in the pediatric populabon.² The disease follows Knudson's two-hit hypothesis and occurs due to biallelic inactivation of the RB1 tumor suppressor gene …

Home-Use Oct For Neovascular Age-Related Macular Degeneration: A Rapid Review, Sneh S. Shah

inSIGHT

Neovascular age-related macular degeneration (nAMD) requires frequent monitoring to identify recurrent exudation and guide treatment with anti-vascular endothelial growth factor (VEGF) therapy.1 Clinic-based optical coherence tomography (OCT) plays a central role in management but provides only intermittent assessments of a disease that changes over time. Home-use OCT technologies have recently been developed as a possible solution, allowing patients to perform self-imaging with remote clinician review and artificial intelligence (AI)-assisted analysis. This rapid review summarizes current evidence on home-use OCT for nAMD, including feasibility, diagnostic performance, clinical usefulness, and challenges related to implementation. Findings from feasibility studies, AI validation analyses, observational …

inSIGHT

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have moved from second-line diabetes medications toward the frontline of type 2 diabetes, obesity, and cardiometabolic care.¹ A meta-analysis of 10 randomized cardiovascular outcomes trials (n = 71,351) demonstrated that longacting GLP-1 RAs reduce major adverse cardiovascular events by 14%, all-cause mortality by 12%, and composite kidney outcomes by 17%.² With GLP-1 RAs usage increasing, ophthalmology is also increasingly encountering patients who have recently started GLP-1 RAs therapy, often alongside substantial improvements in glycemic control.

In the context of GLP-1 RAs ocular complications, two specific topics currently dominate conversations: (1) worsening diabetic …

Dichoptic Therapy Versus Patching – State Of Literature Review, Eve Miller

inSIGHT

Amblyopia is the most common cause of vision loss in children. A meta-analysis performed by Hu et al. 2022 estimated the global prevalence of amblyopia to be 1.36%.¹ Amblyopia is defined as a reduction in best-corrected visual acuity (BCVA) of one or both eyes caused by abnormal neurologic development in the critical period of visual development. Amblyopia may result from unequal refractive error, strabismus or ocular pathology.² Despite treatment of these inciting factors, suppression of one eye remains, resulting in unequal vision. The clinical consequences of untreated amblyopia include permanent reduction in vision in the affected eye and …

Novel Advancements In Glaucoma Surgery, Eshani Ragam

inSIGHT

Glaucoma is a degenerative ocular condition characterized by irreversible vision loss from damage to the optic nerve. This is usually secondary to increased aqueous production or impaired aqueous outflow, resulting in increased intraocular pressure (IOP). Aqueous outflow is managed by the trabecular meshwork and Schlemm’s canal, although secondary pathways may also be involved.¹ Injury to the nerve is permanent, and interventions are primarily aimed at slowing the rate of progression. While eye drops and laser procedures are first-line measures to lower IOP, more persistent or severe etiologies require surgical treatment to preserve sight.² In recent years, advancements in …

Novel Treatments For Keratoconus, Caroline Paik

inSIGHT

Keratoconus is a progressive condition in which the cornea gradually thins and bulges outward, causing it to become steep and irregular. This leads to irregular astigmatism and worsening vision, most often beginning in adolescence or early adulthood.¹ The management of keratoconus has evolved significantly over the past two decades, with novel therapeutic approaches emerging across three critical domains: halting disease progression, improving visual function, and providing surgical alternatives when conservative measures fail. This review examines the latest advances in keratoconus treatment, focusing on innovative approaches that are reshaping clinical practice.
