Removal of the eyeball, leaving eye muscles intact is known as which procedure?

• A. Enucleation
• B. Phacoemulsification
• C. Vitrectomy
• D. Scleral buckle

Answer: (A)

This item tests understanding of how different eye-removal procedures handle the globe and its surrounding structures. Removing the contents of the globe while keeping the sclera and the extraocular muscles intact is known as evisceration. In this approach, the intraocular contents (like the iris, lens, vitreous, etc.) are removed, but the outer shell of the eye and the attached eye muscles stay in place, which helps maintain orbital volume and often allows better prosthetic motility when a prosthesis is fitted. In contrast, enucleation means removing the entire eyeball itself, including the sclera, with the extraocular muscles detached from the globe and typically attached to an orbital implant afterward. Other procedures listed, such as cataract surgery (phacoemulsification), vitrectomy, or retinal detachment repair (scleral buckle), involve different parts or layers of the eye and are not about removing the globe with intact muscles.
