What is Argyle-Robertson Syndrome?How does this pathology manifest itself and what causes it? The answers to all these questions you will receive from the materials of our article. Also in it you will find information about whether this disease is treated and how it is done.
What is Argyle-Robertson Syndrome, only knowthose people who have directly encountered this pathology. In modern medicine, the term is used to refer to a symptom in which the pupils' response to light is absent or greatly weakened. At the same time, reactions to accommodation and convergence are completely preserved (that is, to aim at an object that is near).
Argyle-Robertson syndrome manifests itself not onlymentioned feature. In addition, patients with the described disease often have anisocoria (different sizes in the pupils of the left and right eyes), miosis (constriction) and pupillary deformation. Also, occasionally, in the presence of this syndrome, they can respond to light in a paradoxical way, that is, slightly widening. In this case, the ciliospinal reflex may also be completely absent, that is, the pupils may not expand with painful irritation of the skin of the neck.
In some cases, patients have atrophy and depigmentation of the iris. In this situation, it is said that the pathological process is localized in the region of the anterior dorsal colliculus.
Most often, Argyll-Robertson syndrome is observedwith late syphilis. This pathology is most typical for the reduced form of this disease. By the way, it can be observed in the early stages of the venereal disease.
It should be said that Argyl-Robertson's symptom is also observed in a paralytic syndrome.
Experts argue that the development ofThis phenomenon is primarily associated with the defeat of the neuron (intercalary) visual reflex to light. Also, this pathology can develop because of the increased sensitivity of the papillary fibers to treponemal toxin.
In addition, Argyle-Robertson syndrome is often found in other diseases:
This symptom can also be differentiated from the illness of Adi.
Why there is an inverse syndromeArgyle-Robertson, for which the complete absence of the pupil's reaction to accommodation and convergence is characteristic, and also the preservation of the reaction to light? With regular persistence, the pathology under consideration occurs in a disease such as epidemic encephalitis.
Therapy of Argyll-Robertson syndrome is not performed inconnection with the fact that this is just a symptom of an internal disease. Therefore, all the forces to eliminate this pathology should be directed to treatment of the underlying disease, in which this symptom is observed.
Thus, it is necessary to carry out therapylate or early syphilis, paralytic syndrome, multiple sclerosis, stem encephalitis, diphtheria polyneuropathy, syringobulbia, alcoholism and other listed diseases.
