Mr Chai has shared the OCT result of his eyes. Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-section pictures of your retina/macula – macula is in charge of our centre vision. Ophthalmologist has explained that there is fluid in his eye (in red circle). This may result in edema causing him to have slanting vision.
Mr Chai is scheduled to go for eye injection in his left eye soon. According to his ophthalmologist, the injection will take about 2-3 times depending on how well your eye respond to the injection.
