PARACENTRAL HOMONYMOUS HEMIANOPIC SCOTOMA

PARACENTRAL HOMONYMOUS HEMIANOPIC SCOTOMA Abstract Homonymous hemianopic scotoma is a rare condition. Only a small number of cases have been reported, the last two by one of us in 1930.1 We are reporting another case, which would suggest that the condition is not so rare as one might be led to believe by the paucity of reported cases. The symptom complex consists of: (1) difficulty in reading; (2) absence of reduction of visual acuity; (3) characteristic changes of the fields, namely, a homonymous scotoma that does not include the macula, with maintenance of the peripheral field, with an untouched portion of the field between the periphery and the scotoma, and (4) normal ophthalmoscopic findings.

Abstract

Abstract Homonymous hemianopic scotoma is a rare condition. Only a small number of cases have been reported, the last two by one of us in 1930.1 We are reporting another case, which would suggest that the condition is not so rare as one might be led to believe by the paucity of reported cases. The symptom complex consists of: (1) difficulty in reading; (2) absence of reduction of visual acuity; (3) characteristic changes of the fields, namely, a homonymous scotoma that does not include the macula, with maintenance of the peripheral field, with an untouched portion of the field between the periphery and the scotoma, and (4) normal ophthalmoscopic findings. One word, or part of a word, is seen, but the following words or syllables cannot be made out. The patient may have difficulty in finding the beginning of the next line. As the macula is always spared, References 1. Barkan, Otto, and Barkan, H.: Central and Paracentral Homonymous Hemianopic Scotomas , Am. J. Ophth. 13:853 ( (Oct.) ) 1930. 2. Mills, C.
