Muscles of the Eye01:20

Muscles of the Eye

The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and rotating...
Accessory Structures of the Eye01:17

Accessory Structures of the Eye

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...

Area of Science:

  • Ophthalmology
  • Prosthodontics

Background:

  • Ocular trauma is a leading cause of eye loss, often resulting in a non-functional pthisical eye.
  • Prosthetic rehabilitation options include prefabricated or custom-made eye prostheses.

Observation:

  • A 32-year-old male presented with a pthisical eye due to ocular trauma.
  • The patient sought an eye prosthesis for functional and esthetic restoration.

Findings:

  • A semi-customized scleral shell prosthesis was planned and fabricated for the patient.
  • This approach combines features of stock and custom prostheses.

Implications:

  • Semi-customized scleral shell prostheses provide a functionally and esthetically satisfactory outcome.
  • This technique offers a viable alternative for managing pthisical eyes resulting from trauma.
