In PRESSURE DROP, Morris Potashner learns that he has an acute case of glaucoma and desperately needs an operation to help save his eyes from an almost certain loss of vision. At his glaucoma's advanced stage, Morris's doctor tells him, it is unlikely that either the drops or laser treatment will help. Dr. Lewis tells Morris
that the operation is his only option, but Morris, who vowed
never to set foot in a hospital as a patient after his
father died during a routine kidney - stone operation,
refuses to submit to having his eyes undergo surgery. |
Glaucoma causes damage to the optic
nerve and results in a loss of visual field. The visual field is the
whole area that can be seen from side to side and top to bottom when
looking straight ahead. "Tunnel vision" is the term usually used to
describe the visual field that results from glaucoma. |
