Insights

Angioid streaks (ASs) are a rare retinal condition. Early detection and anti-vascular endothelial growth factor (anti-VEGF) treatment of secondary choroidal neovascularization (CNV) can preserve vision.

Area of Science:

  • Ophthalmology
  • Retinal Diseases
  • Vascular Biology

Background:

  • Angioid streaks (ASs) are crack-like dehiscences in Bruch's membrane, potentially leading to vision loss.
  • ASs can be idiopathic or associated with systemic disorders like pseudoxanthoma elasticum and Paget's disease.

Purpose of the Study:

  • To provide a narrative review of the pathophysiology, current treatments, and future outlook for angioid streaks.
  • To summarize current management strategies for AS-related complications.

Main Methods:

  • Comprehensive literature search across major scientific databases (PubMed, Web of Science, Scopus, etc.).
  • Review of studies focusing on angioid streaks, choroidal neovascularization, and treatment outcomes.

Main Results:

  • Choroidal neovascularization (CNV) is the primary complication of ASs, significantly impacting visual acuity.
  • Anti-vascular endothelial growth factor (anti-VEGF) therapy is the current standard for treating secondary CNV in AS patients.
  • Prompt diagnosis and treatment of CNV offer a good prognosis for maintaining functional vision.

Conclusions:

  • While no definitive cure for ASs exists, anti-VEGF treatment for CNV is effective in preserving vision.
  • Early detection and intervention are crucial for managing AS complications and maintaining visual function.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Barrett Esophagus-II: Clinical Manifestations and Management

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
