Focusing of Light in the Eye01:16

Focusing of Light in the Eye

7.8K
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...

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...

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

22.2K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

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...

Glistenings in multifocal intraocular lenses (IOLs) caused blurry vision in two patients. Exchanging the affected IOLs with clear monofocal IOLs resolved visual disturbances, highlighting the impact of glistenings on visual quality.

Area of Science:

  • Ophthalmology
  • Biomaterials Science

Background:

  • This study examines complications arising from glistenings within single-piece multifocal acrylic intraocular lenses (IOLs).
  • Financial disclosures indicate potential conflicts of interest, as involved personnel are employees or consultants for an IOL manufacturer.

Observation:

  • Two patients experienced blurry or hazy vision attributed to glistenings in their multifocal acrylic IOLs.
  • In vivo slitlamp examinations confirmed severe and moderate glistenings in the IOL optics of the respective patients prior to explantation.

Findings:

  • Explantation of the affected IOLs and replacement with monofocal IOLs led to a 4-line improvement in visual acuity in one patient.
  • Visual symptoms persisted in the second patient even with a hard contact lens, resolving only after explantation and replacement with a glistening-free monofocal IOL.

Implications:

  • Clinically significant straylight can result from glistenings in multifocal IOLs.
  • The presence of glistenings may compromise visual outcomes, particularly in patients requiring high retinal sensitivity.
