Cat's Eye

It is well known that when socializing it is expected of you to look straight ahead and pay attention to the person with eye contact. This norm is used to control people when they are talking to people, as a way of ensuring the said person is paying attention to the conversation. This week when I go to class or when anyone is talking to me I will do everything normally, except look at the person speaking. I will look up at the ceiling or some other fixed point in the room, focusing on it and not…

handles light. As I get to the path light takes as it enters our eyes I will point out four mechanisms that have to function in order for us to see. Each of our eyeballs have six muscles that attach them to our skull. Four of these muscles pull straight and are called rectus muscles. Two of these muscles pull on an angle and are called oblique muscles. The first mechanism is the coordination of these muscles (both eyes) so that our eyes move together. As we open our eyelids (provides protection…

intravitreal injection of anti-VEGF agents in 10 out of 11 eyes, and spontaneously (first tear developing without any previous treatment) in 1 eye. BCVA and CMT did not show significant change after the occurrence of RPE tears. In most cases, tears graded according to Sarraf et al. (12) remained stable over time. Gutfleish et al. (13) studied 37 RPE tears and found that BCVA deteriorated after RPE tear and during follow-up significantly, with 53.2% of eyes progressing to legal blindness at 12…

The retinal pigment epithelium (RPE) is very a important part of the eye; It is responsible for absorption of scattered light, the visual cycle and phagocytosis of photoreceptor outer segment membranes. The protein RPE65 is normally abundantly made in the RPE, unless there is a mutation in the RPE65 gene, caused by a deletion of 4 base pairs. This deletion causes a frame shift and also an early stop on the protein, so the protein is shorter and does not function properly. The mutated gene is…

It’s You Or Me. (It’s probably going to be me.) I entered the first house my heart was racing, my palms were sweating, and I was frantic to get in and out. I had never done this before but I was desperate as if this was the last thing I could do to survive. I yelled out “hello!” No one replied I did a quick look of the downstairs and then slowly and quietly went upstairs all I could hear was my heart beating out of my chest. I was looking for one thing and one thing only and that was gold,…

Epiphora is an excessive tear production (overflow of tears), usually caused by insufficient drainage of the tear film from the eye. The most common cause of epiphora is blockage of the lacrimal ducts located along the nose. This blockage can be from a variety of causes including membrane inflammation, injury, or tumors. Other causes of excess tearing may be corneal disorders, lower eyelid looseness, weakness of facial muscles as the result of a stroke, and eyelashes rubbing on the cornea. [1]…

at first, it is a very complex process made up of many minute parts. The eye is often compared to a camera because similarly it can capture an image, process it, and then store it for later recall. The mechanics behind capturing that image is similar in both. Capturing an image starts as soon as light bounces of an object and hits the eye. The light filters through the cornea and lens into the retina at the back of the eye; a process called refraction. After light passes through the cornea…

inside the eye. The pressure in the eye is raised because fluid (aqueous humor) within the eye cannot get out through the normal drainage system. The increased pressure can cause damage to the nerves of the eye. This can result in loss of vision. It is important to diagnose glaucoma early before damage occurs. Early treatment can often prevent vision loss. There are two main types of glaucoma: • Open-angle glaucoma. This is a chronic condition that causes the pressure inside the eye to rise…

Saying by to Momma Skitles and Daddy Spree, I walked into my new sanitized room. After looking around, I decided to take the bottom of the bunk bed in the far corner. “Better to have one close to the ground and near the closet.” I started making my bed when I got another sudden hunger pang. I doubled over as the intensity of my hunger overtook me. I reached, with trembling hands, into the extra suitcase. Withdrawing a book, I took out my favorite straw. I quickly ripped into the book, not…

Lopez 1 Art 6 Midterm For my midterm paper I decided to choose Ansel Adams' photograph, Moonrise. I decided to choose this because it seemed interesting and we haven't looked over much photography in class so I thought it would be fun to look at it more in-depth. From the picture I can see a graveyard and a small town. The gravestones and the towns are seen very vividly in the scene and the lines which make them up are also very visible. What I found interesting was how the lines, which make…
