Irish surgeon's app can detect changes in the eye that could indicate brain tumours and prevent blindness

SightTrack, one of ophthalmic surgeon Dr Kate Coleman’s apps, can detect in seconds any slight changes in the pattern of blood vessels in the optic nerve in the centre of each person’s eye.

An Irish surgeon has developed apps that can verify a person’s age or detect changes in the eyes that may indicate conditions such as brain tumours or irreversible blindness.

Glaucoma is not usually detected until a person has already lost up to about 25% of their eyesight. In general, this and other undetected eye conditions can cause irreversible blindness in less than 10 years, despite being preventable.
