Focusing of Light in the Eye01:16

Focusing of Light in the Eye

3.0K
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: Treatment

602
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

512
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
  • Refractive Surgery
  • Corneal Physiology

Background:

  • A 27-year-old female patient with myopia seeks to discontinue spectacle and contact lens wear.
  • Past medical history includes childhood strabismus surgery with subsequent mild exophoria.
  • Patient engages in boxing and desires a reversible vision correction method.

Observation:

  • Corrected distance visual acuity: 20/16 in both eyes.
  • Refractive error: OD -3.75 -0.75 x 50, OS -3.75 -1.25 x 142 (manifest); OD -3.75 -0.75 x 44, OS -3.25 -1.25 x 147 (cycloplegic).
  • Ocular health: Normal tear break-up time, Schirmer test, pupil size, anterior chamber depth, corneal thickness, and endothelial cell density. Clear corneas and normal iris configuration observed.
  • Corneal topography and Belin-Ambrósio Deviation (BAD) maps available.
  • Left eye is dominant.

Findings:

  • Patient presents with moderate myopia and astigmatism.
  • Ocular biometry and corneal health appear within normal limits for refractive surgery consideration.
  • Patient expresses a preference for a reversible procedure, such as phakic intraocular lens (pIOL) implantation.

Implications:

  • The patient's ocular parameters suggest potential candidacy for various refractive surgeries, including laser-assisted subepithelial keratectomy (LASEK), laser in situ keratomileusis (LASIK), or small-incision lenticule extraction (SMILE).
  • The recent U.S. Food and Drug Administration (FDA) guidance on LASIK may influence surgical recommendations.
  • Phakic intraocular lens (pIOL) implantation is a viable, reversible option for myopia correction in this patient, with specific IOL type selection pending further evaluation.
