Strabismus, or misalignment of the eyes, is a disorder in which the eyes do not look in the same direction. The condition can occur in people of all ages and has a variety of causes, including anatomical abnormalities, neurological disorders, and refractive errors. Strabismus can lead to significant problems such as double vision, blurred vision, and the development of amblyopia (lazy eye), making early diagnosis and treatment essential to ensure normal vision development.
History of the disease and interesting historical facts
Strabismus has been known to mankind since ancient times. Already in ancient times, doctors described this disease, such as Hippocrates, who mentioned anomalies of visual function in his works. Interestingly, in ancient Egypt, strabismus was considered a sign of divine inspiration and was associated with amulets designed for protection. In the Middle Ages, strabismus was perceived as a kind of vice that was often condemned. With the development of medicine, at the end of the 19th century, with the advent of the first operations to correct strabismus, the attitude towards the disease changed, and attention was focused on its clinical aspects and treatment methods.
Epidemiology
Strabismus is a fairly common disorder, which, according to various sources, affects from 2% to 4% of the population. The problem is more common in children: according to statistics, about 1-2% children under the age of 5 suffer from strabismus. The most common forms include convergent (meso- or exo-) strabismus. Gender differences in the prevalence of the disease are insignificant. However, in some population groups, such as children with neurological disorders, the incidence of strabismus is significantly higher.
Genetic predisposition to this disease
Research suggests that strabismus has a genetic predisposition, with certain genetic mutations being associated with the development of this disorder. Scientific evidence supports the involvement of genes such as STRABISMUS1 and STRABISMUS2, which are involved in the formation of the visual pathways and orbital muscles. In addition, in some cases, abnormalities in chromosomes 1, 5, and 11 have been found, which may also be associated with the development of strabismus. These findings highlight the importance of genetic factors in the development of this disorder, as well as the need for further research.
Risk factors for the development of this disease
Risk factors that contribute to the development of strabismus can be both physical and chemical:
- Physical factors:
- Congenital anomalies;
- Neurological disorders;
- Head and eye injuries.
- Chemical factors:
- Exposure to toxic substances during pregnancy;
- Maternal infectious diseases, including rubella.
- Other factors:
- Heredity;
- Deviations in psychomotor development of children.
Diagnosis of this disease
Diagnosis of strabismus includes several stages and methods:
- Main symptoms:
- Uneven position of the eyes;
- Double vision;
- Eye fatigue when reading.
- Laboratory tests:
- Assessment of refraction and visual function;
- Determining the level of amblyopia.
- Radiological examinations:
- Orbital ultrasound;
- CT or MRI of the head to rule out structural abnormalities.
- Other types of disease diagnostics:
- Refraction tests;
- Ophthalmological examination.
- Differential diagnosis:
- Anomalies of the nervous system;
- Refractive errors.
Treatment
Treatment of strabismus depends on the patient's age and the severity of the condition.
- General treatment:
- Optical correction with glasses;
- Anti-outpatient therapy.
- Pharmacological treatment:
- The use of special drug treatment to improve visual function.
- Surgical treatment:
- Correction of the position of the eye muscles;
- Restorative operations.
- Other types of treatment:
- Speech therapy sessions and sometimes psychotherapy to support children.
List of medications used to treat this disease
Medications used to treat strabismus include:
- Spectacles for vision correction;
- Topical preparations that help relax the eye muscles;
- Medicines to improve nerve conduction in neurological disorders.
Disease monitoring
Monitoring the condition of a patient with strabismus includes several stages:
- Regular eye examinations;
- Evaluation of the effectiveness of the treatment;
- Indicators of deterioration or improvement of vision.
The prognosis in case of timely intervention is often favorable, however complications such as the development of amblyopia or a decrease in quality of life are possible.
Age-related features of the disease
Strabismus in children can take various forms, especially before the age of 5. In older people, occasional cases of strabismus are often observed, resulting from degenerative changes. In each case, it is necessary to take into account individual characteristics and potential concomitant pathologies.
