Does your macula make you see color?

No, it is the cones that are in your retina that allows you to see color. The macula just contains a higher denisty of photoreceptors.


Can your doctor see your blind spot?

A doctor uses a ophthalmoscope to see your optic disc (your blind spot).

How does an ophthalmoscope assist in diagnosis of glaucoma?

It allows the examiner to view the interior of the eye. If the patient has open-angle glaucoma, the examiner can see a cupshaped depression in the optic disk.


What is LCD Display Digital Chargeable Otoscope Ophthalmoscope Set?

Types of otoscope otoscope can be divided into two kinds of direct otoscope and indirect otoscope. Direct ophthalmoscopy Direct ophthalmoscopy can directly examine the fundus, without dilating the pupil, in a dark room for examination, the examiner's eye must be close to the patient's eye, with the right eye to examine the patient's right eye, the right hand holding the ophthalmoscope, sitting or standing on the right side of the patient, the left eye is the other way around, the doctor's other hand to open the patient's eyelid, first placed the ophthalmoscope in front of the patient about 20cm, with +10D lens to check whether the patient's refractive interstitial transparency If the doctor is orthoptotic or has corrective lenses, the refractive power used to see the fundus indicates the refractive condition of the examined eye. Generally, the eye is first made to look straight ahead to examine the optic papilla, then along the retinal vessels to examine the superior and inferior temporal, superior and inferior nasal quadrants, and finally the eye is made to look to the temporal side to examine the macula. The size of the fundus lesion is expressed by the diameter of the optic papilla, and the degree of concavity of the lesion is measured by the refractive index of the lens, which is equivalent to 1mm in 3D. Some examining glasses have a green filter for better observation of the optic nerve fibers and macula.


How does the pupil get its color?

The pupil of the eye is simply a hole in the iris through which one can peer into the eye. It appears black because of the darkness therein; when lit (for example, by an ophthalmoscope) one can see the orange shades of the retina within the eye.The iris, on the other hand, inherits genetically determined pigments that reflect different spectra of light.


What is the function of the macula in the human eye?

The macula is a small area -- less than ¼ inch -- in the center of the retina at the back of the eye .It is responsible for sharp, clear central vision and the ability to perceive color.How does the macula function?Like the film in a camera, the retina receives light rays from the front of the eye and transmits those light rays through the optic nerve to the brain where the rays are converted into images. The densely packed photoreceptor (light-sensitive) cells in the macula control all of the eye's central vision and are responsible for the ability to read, drive a car, watch television, see faces, and distinguish detail. The rest of the retina handles peripheral vision that enables your eyes to see objects off to the side while you are looking forward. There are two types of photoreceptor cells in the cornea -- rods and cones. The rods provide vision at low light levels, while the cones provide sharp vision and discrimination. Because the macula contains a high concentration of cones, straight-ahead vision is in sharp focus, particularly in bright light. Most of the rods are located in the periphery of the retina, so faint objects are more visible if you do not look directly at them. A dim star, for instance, is best seen when your eyes are not aimed directly at it.What problems can occur with the macula?The most common cause of functional blindness in people over the age of 60 is macular degeneration, a deterioration or breakdown of the macula. Damage to the macula results in the loss, either partial or complete, of ability to see objects clearly in the center of vision. Although not totally blind, the person has difficulty performing tasks that require "straight-on" vision, such as driving a car, reading, or watching television. Because peripheral vision is not affected, the person can adapt somewhat to the loss of central vision and continue to pursue some normal daily activities, such as walking, without assistance. There are two types of macular degeneration. The "dry" form is usually the result of aging and thinning of the macula's layers, and the "wet" form occurs when abnormal blood vessels under the retina leak fluid and blood, causing scarring. Vision loss with dry macular degeneration occurs gradually over a number of years, and the affected person may not be aware of any problem. Dry macular degeneration is the less serious of the two forms. With the wet form of this disease, central vision capabilities can be damaged rapidly. Early detection usually results in more successful treatment.
