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...

Portal Hypertension01:22

Portal Hypertension

19
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...

Area of Science:

  • Ophthalmology
  • Vascular Biology
  • Retinal Imaging

Background:

  • Retinal cavernous hemangiomas are rare vascular tumors.
  • They are typically isolated but can present with other vascular anomalies.

Purpose of the Study:

  • To document two unique cases of retinal cavernous hemangiomas.
  • To investigate their association with retinal macrovessels.

Main Methods:

  • Observational case study of two patients.
  • Comprehensive ophthalmic examination, fundus photography, and fluorescein angiography were performed.

Main Results:

  • Both patients presented with unilateral retinal cavernous hemangiomas.
  • Associated findings included dilated retinal veins (retinal macrovessels) and capillary nonperfusion.
  • Fluorescein angiography revealed fluid-erythrocyte levels within the hemangiomas.

Conclusions:

  • Retinal cavernous hemangiomas can be associated with significant retinal vascular abnormalities.
  • These cases emphasize the importance of thorough vascular assessment in patients with retinal cavernous hemangiomas.
