Electron microscopes pass beams of electrons through a specimen and have a much greater resolution than a light microscope.

The best light microscope can show details that are 0.2µm apart and need a magnification of roughly x1500 so that our eyes can see it - this allows us to see larger cell structures.

The Optical Coherence Tomography (OCT) is the most current and precise technology that is used for diagnostic imaging of the eye. It is similar to an MRI or ultrasound but it is even more precise, with sub-micrometer resolution. The OCT uses non-invasive lasers that are capable of producing cross-sectional and three-dimensional images of the retina.  By taking thousands of scans per second, the OCT ensures high resolution and accuracy for imaging different states of disease in the retina.

Eye diseases such as age-related macular degeneration, diabetic retinopathy, macular edema, and glaucoma can be diagnosed and monitored through the use of the OCT. In addition, the OCT can detect eye conditions such as macular holes, epi-retinal membranes, and retinal detachments.

The above equation can be rearranged in order to calculate the actual length of the cell and the magnification used as well as the length of the image.

Figure 1. shows a cross-section of the foveal region of the retina, which is where our central vision is located. The image also shows the ten layers of the retina. Figure 2. shows a cross-section of the optic nerve head, which is where nerve impulses carrying visual information are sent to the brain. It is crucial to maintain the health of the retina and the optic nerve as they are both mandatory for sight.

It is important to take the OCT if your doctor requests for it. Many eye diseases and conditions do not have any symptoms. By the time the symptoms present themselves, it may already be too late and lost vision cannot be recovered.

Their resolution can show details that are 0.0001µm apart - allowing us to clearly see inside the parts of a cell e.g. inside a chloroplastclosechloroplast Part of a cell that carries out photosynthesis.

Magnification can be calculated using a scale bar. This is a line drawn near the photograph or drawing which has a label showing the actual length of the bar before being magnified.
