Diabetic Retinopathy01:27

Diabetic Retinopathy

11
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...

Glaucoma: Overview01:25

Glaucoma: Overview

1.7K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.7K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

652
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Transient Ischemic Attack l: Introduction01:26

Transient Ischemic Attack l: Introduction

2
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...

Hyperglycemia01:29

Hyperglycemia

2
Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose...

Area of Science:

  • Ophthalmology
  • Cardiology
  • Endocrinology

Background:

  • Central retinal artery occlusion (CRAO) is a critical condition leading to sudden vision loss.
  • Risk factors for CRAO typically include embolic and thrombotic events, but less common causes warrant investigation.

Purpose of the Study:

  • To present a case of central retinal artery occlusion (CRAO) in a patient with severe hypertriglyceridemia.
  • To emphasize the importance of lipid profiling in the diagnostic workup of CRAO.

Main Methods:

  • A 46-year-old male patient presented with acute visual impairment.
  • Diagnostic evaluation included funduscopic examination, laboratory tests for lipid profile, and exclusion of cardiac/carotid embolic sources and hypercoagulability.

Main Results:

  • The patient was diagnosed with central retinal artery occlusion (CRAO).
  • Markedly elevated triglyceride levels were identified as the primary abnormality.
  • Despite successful triglyceride reduction through diet and medication, visual recovery was limited.

Conclusions:

  • Central retinal artery occlusion (CRAO) necessitates a comprehensive evaluation for embolic and thrombotic etiologies.
  • A fasting lipid panel is a cost-effective and essential component in the workup for central retinal artery occlusion (CRAO).
  • Hypertriglyceridemia should be considered a potential underlying cause of CRAO.
