What is the value of the convergence reflex of the eyes?
the convergence reflex is responsible for keeping the eyes aligned and focused on an object
What is convergence reflex?
The convergence reflex in the eyes os responsible to keep your eyes aligned and focused on an object. Try moving a pen towards and away from your face; your eyes will follow the object naturally and keep it in focus.
Can medical marijuana be used to treat convergence insufficiency?
No. Marijuana is known to potentially decrease the accommodative amplitude of the eyes (reduce the eyes ability to focus at near). The eyes use accommodation as a way of facilitating convergence, so the lower the accommodative amplitude, the harder it is to converge the eyes. In short, using marijuana will make convergence more difficult and is therefore NOT a treatment option for convergence insufficiency; It's a condtraindication.
Does convergence mean nearsightedness?
Convergence is the movement of the eyes towards each other as they focus on something moving towards the patient's nose.
Medial movement of the eyes during focusing on close objects?
Convergence
The rotation of the two eyes in their sockets to focus on a single object?
Convergence
When eyes are directed toward the medial line?
Convergence is the term for the eyes moving medially to focus on a close object. Convergence is one of the phenomena tested during the physical exam when extraocular movements are assessed.
In the experiment on the convergence reflex what happened to the position of the eyeballs as the object was moved closer to the subject's eyes?
I'm assuming you are talking about the convergence reflex. If you are, they shifted toward the center of the object to focus and eventually see it.
What causes convergence over land and divergence over the ocean?
The cause is friction
What extrinsic eye muscles control the movement of the eyes during convergence reflex?
Medial Rectus
What is the value of the convergence reflex in the eye?
Acuity and alignment for proper identification and understanding are the values of the eyes' convergence reflex.Specifically, the term identifies the tendency of both eyes to fixate on an object in front of the individual in question. Both eyes move inwardly toward the nose. This action permits the retina to receive a clear, sharp image.
Which term describes the simultaneous inward movement of both eyes toward each other to maintain single vision?
The simultaneous inward movement of the eyes is known as convergence. When both eyes are aligned onto a target, the brain should perceive a single image. Slight inaccuracies in convergence can cause a person to see double vision, or diplopia. Because the convergence visual system is also tied to the focusing system, many people who have problems with convergence also have problems with focusing and thus have blurred vision. This linkage between focusing and convergence is known as accommodative conververgence.If the eyes cannot converge accurately to achieve single vision, usually the person will have a convergence insufficiency, convergence excess, or strabismus. Convergence insufficiency means that the eyes do not turn inwards enough to lock onto a target usually up close. This will result in double vision, difficulties in reading, and poor reading comprehension particularly in school-aged children who are not treated or are never diagnosed because they assume it is normal.Convergence excess is when the eyes turn in too much. Symptoms can be quite similar to convergence insufficiency except the treatment is more challenging. The gold standard for treatment for both convergence insufficiency and convergence excess is vision therapy or orthoptics. This involves exercises and activities to improve muscle coordination and focus through a doctor-directed therapy program. The duration of treatment varies on the patient's age and the severity of the condition. On the otherhand, strabismus refers to eyes that are misaligned even while looking straight ahead and not just the inward movement of the eyes. Treatment for strabismus can include just getting a pair of glasses, to adding prism to your lens correction, vision therapy, and eye muscle surgery if the other options are unsuccessful.
