Focusing of Light in the Eye01:16

Focusing of Light in the Eye

5.4K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

8.7K
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,...

Glaucoma: Overview01:25

Glaucoma: Overview

1.2K
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

1.2K
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

961
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Area of Science:

  • Ophthalmology
  • Biomedical Engineering
  • Medical Imaging

Background:

  • Pathologic myopia (PM) is a leading cause of irreversible vision loss globally.
  • Posterior staphyloma, a key feature of PM, involves scleral thinning and ectasia, affecting the macula and optic nerve.
  • Vision-threatening complications like myopic traction maculopathy (MTM) and myopic macular neovascularization (MNV) are common in PM.

Purpose of the Study:

  • To highlight the significance of posterior staphyloma in PM.
  • To discuss the role of scleral integrity in disease progression.
  • To explore advanced imaging techniques for assessing PM-related structural changes.

Main Methods:

  • Review of existing literature on pathologic myopia and posterior staphyloma.
  • Discussion of advanced imaging modalities including 3D MRI, ultra-widefield OCT (UWF-OCT), and polarisation-sensitive OCT (PS-OCT).
  • Emphasis on the biomechanical role of the sclera and vitreoretinal interface.

Main Results:

  • Posterior staphyloma is a critical indicator of localized scleral pathology in PM.
  • Vitreoretinal traction and macular neovascularization are significant drivers of visual impairment in PM.
  • Advanced imaging like UWF-OCT and PS-OCT provide detailed insights into posterior segment alterations and scleral structure.

Conclusions:

  • Reinforcing the posterior sclera presents a potential therapeutic strategy to slow PM progression.
  • Early detection of structural changes using advanced imaging is crucial for timely intervention.
  • Understanding scleral biomechanics and posterior segment changes is key to preventing irreversible vision loss in PM.
