Most retinal detachments are treated with a technique known as <u>scleral banding</u>, which involves placing a silicone band over the detached area, forcing the layers of the retina together.
What is scleral banding or buckle?
A scleral buckle is one of several ophthalmologic procedures that can be used to repair a retinal detachment. Retinal detachments are usually caused by retinal tears, and a scleral buckle can be used to close the retinal break, both for acute and chronic retinal detachments.
Scleral buckles come in many shapes and sizes. A silicone sponge (with air filled cells) is a cylindrical element that comes in various sizes. An encircling band is a thin silicone band sewn around the circumference of the sclera of the eye. A solid silicone grooved Tyre element is also used. Buckles are often placed under a band to create a dimple on the eye wall.

Answer:
Most likely he has injured his <u>Calcaneal tendon</u> and the bulge is <u>triceps surae or calf muscle.</u>
Explanation:
The calcaneal tendon is the thickest tendon, which is present at the back of the lower leg and begins at the middle of the calf. It is covered with skin and fascia and connects the bones with the muscles.
The calf muscles or the triceps surae, are the muscles present in the calf of the leg.The calf muscles act via the tendon and cause flexion of the knee and the ankle.
<u>While exercising, an overuse of the calcaneal tendon, can result in pulling of the calf muscles from the Achilles tendon. Thus causing a tear in the calf muscle, which appears like a bulge.</u>
Since, the options have not been given the question is incomplete. The complete question is as follows:
Indicate which syllable receives emphasis when pronounced. optometry
a. op
b. tom
c. e
d. try
Answer: b. tom
Explanation:
A syllable can be defined as the unit of pronunciation, that have one vowel sound, that is with or without surrounding consonants. It may have a whole or part of the word.
In the given word, optometry, tom is the syllable and it receives the emphasis when pronounced because of the presence of vowel "o" increasing the weight-age over the consonants t and m on pronunciation.
A <u>reservoir</u> is the primary habitat in the natural world from which a pathogen comes.
<h3>Pathogen:</h3>
An organism that causes the disease is called a pathogen. Your body is already teeming with bacteria. However, these organisms only become an issue if your immune system is compromised or if they are able to get into an area of your body that is typically sterile. Different from other organisms, pathogens can spread disease once they enter the body. A host is all that a pathogen requires to grow and survive.
The pathogen enters a host's body, avoids the immune system's defenses, and uses the host's resources to replicate before leaving and infecting a new host. Depending on the type, there are various methods by that pathogens can be spread. They can be transmitted by skin-to-skin contact, biological fluids, airborne particles, feces, touching a surface, and more. The reservoir is any population of organisms (or any environment) that harbors the pathogen and transmits it to the target population.
