Diabetic Retinopathy

55
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration...

Area of Science:

  • Ophthalmology
  • Toxicology
  • Public Health

Background:

  • Corneal ulcers are a rare but serious complication of methamphetamine abuse.
  • Ocular complications from illicit drug use may be missed without a thorough social history or lab confirmation.

Observation:

  • A 48-year-old male presented with bilateral vision loss and was found to have stromal corneal ulcers.
  • Physical signs included pockmarks, poor dentition, and jittery behavior, raising suspicion for methamphetamine use.

Findings:

  • Bilateral corneal ulcers with infiltrates were diagnosed.
  • Laboratory testing confirmed methamphetamine use in the patient.

Implications:

  • Recognizing physical signs of methamphetamine abuse is vital for diagnosing ocular complications.
  • Early intervention and patient education regarding drug-induced vision loss are critical.
  • Referral to addiction services is essential for patients with methamphetamine-associated ocular issues.
