A ruptured globe occurs when rapid intraocular pressure elevation secondary to blunt trauma results in eyewall failure. [3] The rupture site may be at the point of impact but more commonly occurs at the weakest and thinnest areas of the sclera. [4] Regions prone to rupture are the rectus muscle insertion points, optic nerve insertion point ...
Treatment of closed globe trauma begins with the division of the eye into zones, each with unique anatomical structures and injury patterns: Zone I: the conjunctiva and corneal surface; the most common injuries seen in this zone are foreign debris retention by the conjunctiva or corneal epithelium/stroma, as well as corneal abrasions.
Canthotomy (also called lateral canthotomy and canthotomy with cantholysis) is a surgical procedure where the lateral canthus, or corner, of the eye is cut to relieve the fluid pressure inside or behind the eye, known as intraocular pressure (IOC). [1] The procedure is typically done in emergency situations when the intraocular pressure becomes ...
ICD-9-CM. 16.4. MeSH. D015353. [edit on Wikidata] Enucleation is the removal of the eye that leaves the eye muscles and remaining orbital contents intact. This type of ocular surgery is indicated for a number of ocular tumors, in eyes that have sustained severe trauma, and in eyes that are otherwise blind and painful. [1]
Eye injury. Eye injury. A small piece of iron has lodged in the margin of the cornea. Specialty. Ophthalmology, neurology. Physical or chemical injuries of the eye can be a serious threat to vision if not treated appropriately and in a timely fashion. The most obvious presentation of ocular (eye) injuries is redness and pain of the affected eyes.
Specialty. Ophthalmology. Intraocular hemorrhage (sometimes called hemophthalmos or hemophthalmia) is bleeding inside the eye (oculus in Latin). Bleeding can occur from any structure of the eye where there is vasculature or blood flow, including the anterior chamber, vitreous cavity, retina, choroid, suprachoroidal space, or optic disc.
D018918. [edit on Wikidata] Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the volume of the anterior chamber ...
Treatment options include contact lenses and intrastromal corneal ring segments for correcting refractive errors caused by irregular corneal surface, [7] [8] corneal collagen cross-linking to strengthen a weak and ectatic cornea, [9] or corneal transplant for advanced cases.
