In Book I Oliver Sacks describes his visit to Pingelap and Pohnpei in the Caroline Islands (now a part of the Federated States of Micronesia). On Pingelap (population 700) 5-10% of the people are completely colorblind; i.e. they have a rare hereditary condition called achromatopsia in which the retina has no functional cone cells. Rod cells, which normally provide peripheral and night vision, are their only source of vision. While partial colorblindness is common, achromatopsia is normally very rare. Sacks and Knut Nordby, a Norwegian scientist who is himself achromatopic, examined dozens of achromatopes on Pingelap and in a village of Pingelapese people on the larger Pohnpei.
In Book II Sacks takes the reader to Guam where he investigates (with his friend John Steele, a neurologist who lives on the island) the neurological disease called "lytico-bodig." The "lytico" form of this disease is a progressive paralysis similar to amyotropic lateral sclerosis, while the "bodig" form resembles parkinsonism. Both appeared in Guam after the Second World Way and now seem to be dying out. However, no one has ever determined their cause.
Sacks tells the story of his visit, while also discussing various hypotheses that have been considered and discarded over forty years of study. The last section of the book describes a trip to Rota, a small island north of Guam, where Sacks visits a forest of cycad trees and discusses his life-long fascination with these primitive plants.
Elinor Golden has had trouble reading and writing ever since a golf ball hit her in the head as a child and left her with permanent minor brain damage. Otherwise quite intelligent and fully functional, she has stumbled through school unable to perform assigned tasks, unwilling to make the nature of her problem any more public than she has to, and often alone with it, since few teachers, even those who know the problem, know how to help her. Even her father, a doctor, is baffled.
It is 1943 and, as the U.S. enters the war, her attention is diverted to problems bigger than her own. She joins a volunteer corps that keeps watch for enemy planes approaching the New England coast. In the course of this purposeful work, she is paired on watch with a young teacher who finds a way to help her read by having her trace letters with her finger. Both her new work and her new reading strategy empower her, and help her cope with the crisis of her parents' separation and the departure of her lifelong friend, Jed, for Dartmouth.
She leaves school and joins a group of paid volunteers to do war work, discovering new areas of competency and satisfaction after years of feeling like a failure. At the same time her friend, Jed, discovers something new in her, and friendship turns to romance as personal hope blossoms in the midst of trouble and war.
Summary:A witch doctor treated a man for trachoma with a caustic root, and the man went blind. Terrified and depressed, he sat in the doorway of his home for two years while "his wives ministered" to him. One night he went off on his own and "fell into a dry well and died upside down."
Angelou’s four stanza poem is narrated by an elderly person, probably a woman. In each of the stanzas, the proud and forthright speaker dismisses the desire to stay alive. She sizes up her circumstances pragmatically--the inconveniences and disabilities. She can no longer bother with the print that has become "too small," the food that is "too rich," the tiring concerns of her children, and, finally, the weariness of life. Each is addressed in its own stanza, but the concluding refrain is the same; she will give up reading, then eating, then listening--and then life. "Today," she says rather convincingly in her final line, "I’ll give up living."
Summary:The poem describes the visual sensations of a person's "good year" as he is going blind. "Autumnal light / gave to ordinary things the turning / beauty of leaves . . . . " Normal colors became spectacular in their new manifestations and meanings. He was able "to look inside the top glow of each object" and discern its "inner texture." Even God might have such visions as these, if he "were only half the man he is."
Summary:A patient suffers a mysterious eye ailment that baffles the doctors. Yet suddenly, the affliction resolves, and the patient describes the simple joys of tears and what they symbolize. The mood is shattered as the patient discovers that despite all the "mercy' that tears bring, they can also be deadly, as an "AIDS-related virus" is discovered in tears.
