Going back a little back, I want to mention that the retina is a layer of tissue in the back of the eye that senses light and sends images to the brain. The macula is located at the center of this nervous tissue. The macula allows to focus the view toward the Center and acuity necessary for reading, driving, and clearly see the details. That’s why we need to be very careful with our eyes, because the retina is an essential part for a healthy view. And I would like to emphasize that to solve some problems that are caused in our eyes, has been created the ophthalmoscope which is an instrument, with several lenses and mirrors that illuminate the interior of the eye through the pupil and lens, allowing examination of the retina or fundus. There are many ways, being the most commonly used of the manual ophthalmoscope designed for amplified vision (15 x) direct, with a source of light projected through a mirror or Prism to the bottom of the patient’s eye, which is reflected in the retina and which coincides with the line of sight of the observer from the opening. The increase obtained by using the direct ophthalmoscope is due to that the eye itself serves as a simple magnifying glass by cornea and crystalline lens. Thanks to this device, many clinics have seen benefiting with these services, because in one way or another it allows them to better see the structures corresponding to the retina, which is very small and therefore it is difficult to see. In addition, through its use ophthalmologists can make a better prognosis on our sight. In a few words, we can say that the ophthalmoscope came to make life easier for them.
