Photoreceptors and Visual Pathways

11.2K
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,...

Accessory Structures of the Eye

4.7K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

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...

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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

1.1K
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
  • Traumatology
  • Medical Imaging

Background:

  • Lightning strike injuries can manifest with various ocular complications affecting both anterior and posterior eye segments.
  • While direct ocular trauma from lightning is documented, indirect mechanisms leading to specific pathologies are less understood.

Observation:

  • A 77-year-old woman presented with sudden visual loss in her right eye and scalp thermal injury following an indirect lightning strike.
  • Slit lamp examination and optical coherence tomography (OCT) revealed a full thickness macular hole in her right eye.
  • Best corrected visual acuity was LogMAR 0.46 (right) and 0.12 (left), with no other ocular findings.

Findings:

  • The case represents the first documented instance in the UK of an indirect lightning-induced full thickness macular hole.
  • Initial conservative management with non-steroidal anti-inflammatory drug eye drops yielded minimal improvement.
  • Follow-up revealed persistent visual acuity deficits and the macular hole, necessitating surgical consideration.

Implications:

  • Optical coherence tomography (OCT) is crucial for diagnosing macular holes, a condition often requiring surgical intervention.
  • This case highlights the potential for indirect lightning strikes to cause significant, isolated posterior segment damage.
  • Understanding these indirect injury mechanisms is vital for appropriate ophthalmic management following lightning exposure.
