Purpose: To describe the devastating ophthalmic sequelae of methamphetamine use disorder in two patients who developed vision loss from ocular complications, including keratitis and endophthalmitis.
Observations: Case 1 is a 26-year-old male with hepatitis C, poorly controlled type 1 diabetes, and chronic methamphetamine use who presented with a corneal ulcer in the left eye. Corneal culture grew and , prompting antibiotic therapy. Follow-up exam showed peripheral corneal ulceration OD and diffusely vascularized and scarred cornea OS, although nonadherence was reported. Vision eventually worsened to hand motions OD and light perception OS.Case 2 is a 44-year-old woman with hepatitis C, acute myeloid leukemia, dry eye syndrome secondary to chronic graft-versus-host disease (GVHD), and chronic methamphetamine use who presented with a diffuse corneal infiltrate and hypopyon. She underwent emergent corneal transplantation, vitrectomy, and broad-spectrum intravitreal and intravenous antibiotics. Vitreous cultures were positive for . However, progressive disease eventually required enucleation despite initial globe salvaging measures.
Conclusions And Importance: These two patient cases highlight the risk of vision loss or blindness due to the detrimental effects of chronic methamphetamine use on the eye, including the potential for keratitis and endophthalmitis. Given the increasing prevalence of methamphetamine use disorder in the United States, further understanding of these toxicities and preventive strategies are needed.

Background: Opioid use disorder remains a critical healthcare challenge as current therapeutic strategies have limitations resulting in high recurrence and deaths. We evaluated safety and feasibility of focused ultrasound (FUS) neuromodulation to reduce substance cravings and use in severe opioid- and co-occurring substance use disorders.
Methods: This prospective, open-label, single-arm study enrolled 8 participants with severe, primary opioid use disorder with co-occurring substance use.

Targeting VMPFC-amygdala circuit with TMS in substance use disorder: A mechanistic framework.
Addict Biol
January 2025
Department of Psychiatry and Behavioral Sciences, University of Minnesota, Minneapolis, Minnesota, USA.
The ventromedial prefrontal cortex (VMPFC), located along the medial aspect of the frontal area, plays a critical role in regulating arousal/emotions. Its intricate connections with subcortical structures, including the striatum and amygdala, highlight the VMPFC's importance in the neurocircuitry of addiction. Due to these features, the VMPFC is considered a promising target for transcranial magnetic stimulation (TMS) in substance use disorders (SUD).
