After fluorescein is injected, ensure that the patient is not suffering from an allergic reaction or shock. Fluorescein may have an allergic reaction or shock as side-effects that can, if serious enough, result in death. If there are signs of an allergic reaction or shock, stop photographic operation immediately and give appropriate first-aid treatment.
56
We suggest that you check for any side effects of fluorescein, by performing a preliminary test. Fluorescein is capable of producing lethal side-effects.
Check for side-effects of mydriatic drops. Mydriatic drops may lead to severe side-effects.

Ensure that nobody’s hands are placed between the
43
main body and the lower arm of the instrument. If the main body is tilted, your hands may get caught in between and be pinched and injured.
51 56
Ensure that nobody’s hands are placed between the
chin rest support and the lower or upper arm of the instrument. This warning is primarily aimed at the patient.
When the main body is moved, the hands may get caught in between and be pinched and injured.
43 51 56
Do not hold the head strap or chin rest support when
transporting the instrument. Such an action may lead to dropping the instrument and can cause bodily harm.
33
Do not replace the lamp immediately after it goes. The lamp unit will still be extremely hot. You may get burned if you touch it.
73
Do not replace any filters directly after the lamp is turned
off. The lamp unit will still be extremely hot. You may get burned if you touch it.
Pay close attention to the clearance between the
objective lens and the patient. If the main body is moved, the objective lens may bump against the patient’s eye or nose, inflicting a minor injury.

Ensure that the instrument is transported by two
persons, both holding the bottom of the instrument. Single-handed transportation is very dangerous, possibly causing the person carrying the instrument to hurt his back or get injured if the instrument is dropped. Holding a part of the instrument other than the bottom, your hands may get caught (and pinched) which could result in the instrument being dropped.
