Eye strain, also known as asthenopia (from astheno- 'loss of strength' and -opia 'relating to the eyes'), is a common eye condition that manifests through non-specific symptoms such as fatigue, pain in or around the eyes, blurred vision, headache, and occasional double vision. [1]
Patients suffering from blepharospasm also report sensory symptoms including sensitivity to light, [14] [15] dry eyes, [16] and burning sensation and grittiness in the eyes. [4] Although such symptoms tend to precede the onset of the blepharospasm, they may both be due to a common third factor.
Asthenopic (eye strain) symptoms in the eye are responsible for much of the severity in CVS. Proper rest to the eye and its muscles is recommended to relieve the associated eye strain. Observations from persons experiencing chronic eye strain have shown that most people who claim to be getting enough sleep are actually not.
Since spasm of accommodation is a result of contraction of the ciliary muscle, the goal would be to relax the ciliary muscle. New studies conducted on rats using perilla frutescens aqueous extract have shown to relax the ciliary muscle. Since there are no known drugs to treat this eye condition, perilla frutescens in an aqueous extract form may ...
Eyes may also be less able to adapt to variable weakness, because extraocular muscles use visual rather than proprioceptive (body position-sensing) cues for fine-tuning. Immunologic hypotheses proposes that there may be differences in the antibodies in ocular MG versus generalized MG that may favor the muscles responsible for eye movement and ...
The symptoms can be the same between these two flu strains. However, Dr. Russo says that “flu A usually causes more severe disease than flu B.” Meaning, if you have flu A, your doctor may want ...
The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
Strabismus is an eye disorder in which the eyes do not properly align with each other when looking at an object. [2] The eye that is pointed at an object can alternate. [3] The condition may be present occasionally or constantly. [3] If present during a large part of childhood, it may result in amblyopia, or lazy eyes, and loss of depth ...
