Ellie Lee‚ a 74-year-old patient‚ is admitted to the hospital in the same-day surgery unit for nasal surgery. The patient is legally blind. The patient was diagnosed with a genetic disease‚ recessive retinitis pigmentosa (RP)‚ which results in degeneration of the photoreceptor cells. A patient with RP has a progressive loss of visual acuity‚ progressive night blindness‚ and progressive loss of peripheral

considerable acanthosis with broadened rete ridges causes deprivation of distant epithelial cells from blood supply and appearance becomes edematous and swollen. These necrotic cells undergo desquamation. Also leaving cleft in the surface of the epithelium. Verrucous projections are formed in this way in between clefts. At a later stage both the verrucous projections and the clefts undergo keratinization [5]. This is a case of verrucous hyperplasia with candidal superinfection in a background of

pilocarpine (Fig. 5)‚ 0.45 mg. per kilogram of atropine was administered intraperitoneally. Nine minutes after the atropine‚ the myopia had increased and then remained high until a larger dose of atropine‚ 0.8 mg. per kilogram‚ was given. The pupil contracted maximally during the experiment‚ and dilated only after the second dose of atropine. The remarkable fluctuations in refraction after 50 mg. per kilogram pilocarpine (Fig. 5) were not due topilocarpine (Fig. 5)‚ 0.45 mg. per kilogram of

Elizabeth Sarubbi December 9‚ 2014 Psychology Chapter 4 1. Would you say that TN’s blindness is caused more by a problem with sensation or a problem with perception? Why do you think so?

TN’s blindness he goes around the objects but he can’t see what they are. 2. Do you think that even sighted people benefit

By disecting the eyeball of a dog‚ researchers found that about 10% of the photoprecepters are cones. Cones are responsible for helping the brain detect colors. The photoreceptors in our eyes are 100% cones. This means that we can process all the colors and see them more vividly. A dog can’t tell the difference between red‚ yellow‚ orange‚ or green but they can see whites light blues‚ purples and different shades of grey. Besides just the cones‚ there are other photoreceptors known as rods
