An ophthalmological measuring apparatus has a display that displays a digital image of an imaged ocular fundus of a subject eye. A specifying device specifies an arbitrary point on the displayed digital image. An extracting device extracts from the displayed digital image an image region whose brightness value is higher than a brightness value of the specified arbitrary point.

Ophthalmological measuring apparatus

An eye fixation monitor for ophthalmological examination is provided which is capable of automatically monitoring the eye fixation without the ophthalmologist being required to initialize the eye fixation value. The eye fixation is monitored using deviation signals derived on the basis of the eye image formed on photoelectric transducers. The eye fixation monitor is provided with means for inducing the patient to assume the eye fixation state, and to resume the monitoring automatically after the examination has been interrupted by excessive deviation of the line of sight from the eye fixation target.
