Summary
This review compares orbital implants, finding porous polyethylene offers superior prosthesis motility and fewer extrusion risks compared to hydroxyapatite. All orbital implants require wrapping for optimal outcomes.
Area of Science:
- Ophthalmology
- Biomaterials Science
- Surgical Innovation
Background:
- Orbital implants are crucial for restoring aesthetics and function after enucleation.
- Various implant materials exist, including autoplastics and alloplastics, with porous and nonporous options.
Purpose of the Study:
- To differentiate orbital implant types, detailing their pros and cons.
- To assess prosthesis motility post-orbital implant insertion.
- To identify risks associated with current implant wrapping techniques.
Main Methods:
- A comprehensive literature review of 67 articles was conducted.
- Comparative analysis of implant materials like hydroxyapatite (HA) and porous polyethylene.
- Evaluation of implant wrapping materials and techniques.
Main Results:
- Porous implants, particularly porous polyethylene, demonstrate superior prosthesis motility and minimal extrusion rates.
- Hydroxyapatite implants, while common, present disadvantages including cost and potential for damage.
- All orbital implants necessitate wrapping, which aids insertion, muscle reattachment, and protects against exposure.
Conclusions:
- Porous polyethylene orbital implants offer advantages over HA implants regarding motility and extrusion.
- Proper implant wrapping is essential for successful outcomes, preventing complications like exposure and erosion.
- Further research into optimal implant materials and wrapping techniques is warranted.

01:17Accessory 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...
01:23Ophthalmic Drug Delivery Systems
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
01:20Muscles 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...

01:05Mechanism of Ciliary Motion
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...
