| Patients with EMB toxicity had significantly greater worst visual acuity and worst color vision discrimination than both comparison groups. |
|
| Testing of visual acuity and color vision should be performed when EMB is to be used. |
|
| The most serious potential adverse effect of EMB is ocular toxicity manifested by optic or retrobulbar neuritis, which exists in two forms and may affect one or both eyes. |
|
| Other aircraft that may fall into this category are the Fairchild Metro, Jetstream 31, and Embraer EMB 110 Bandeirante. |
