Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

Diabetic Retinopathy

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

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...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...

Area of Science:

  • Ophthalmology
  • Neurology
  • Obstetrics

Background:

  • Pre-eclampsia is a serious pregnancy complication characterized by high blood pressure.
  • Visual disturbances are known symptoms of pre-eclampsia, but permanent visual field defects are rare.

Observation:

  • A 40-year-old woman presented with persistent bilateral concentric visual field defects.
  • These defects began 10 years after a severe, uncontrolled pre-eclampsia requiring uterine curettage at 24 weeks gestation.

Findings:

  • Ophthalmic examination, including visual acuity, color vision, and intraocular pressure, was normal.
  • Fundus examination revealed a reduced arteriole-to-vein ratio bilaterally.
  • Humphrey Field Analyzer confirmed bilateral concentric visual field defects.
  • Visual Evoked Potentials, Electroretinography, and cranial MRI were normal.

Implications:

  • This case suggests a potential link between severe pre-eclampsia and permanent visual field defects.
  • Ophthalmologists should consider pre-eclampsia as a potential cause of unexplained visual field loss.
  • Further research is needed to understand the pathophysiology and long-term visual consequences of severe pre-eclampsia.
