Health Sciences University Faculty Member, Ophthalmology Specialist Prof. Dr. Speaking to Anadolu Agency (AA), Osman Melih Ceylan said that nystagmus is defined as involuntary and rhythmic eye movements in one or both eyes.
Stating that eye tremors can be physiological or can be caused by pathological reasons, Ceylan stated that this can cause complaints such as blurring in vision, double vision, dizziness and movement of the image, as its intensity and speed change in different aspects of gaze.
Ceylan explained that eye tremor patients may be accompanied by refractive errors, amblyopia, strabismus, cataracts, optic nerve and retinal diseases, and said, “Especially since astigmatism is a risk factor in terms of amblyopia, eyeglasses should be given. The gaze position in which eye tremors decrease or disappears is called zero point. The zero point is to bring the face, chin or head to an abnormal position in order to minimize the patient’s complaints. Abnormal head position causes cosmetic problems as well as muscle and skeletal system disorders. ” gave the information.
Stating that eye tremors can develop congenitally or later, Ceylan said:
“Tremor develops in some of the patients due to eye and neurological diseases, while the cause is unclear in the rest. These cases constitute 65-75% of childhood eye tremors. 40-64% of the cases are accompanied by strabismus. Excitement, exertion. The intensity of the tremor increases while the eyes look carefully to a point. Genetic transition can be seen in patients with eye tremor. Eye tremor develops in the later period of life due to trauma, neurological and vascular diseases. . “
“On examination, the visual level and the type of accompanying strabismus are evaluated”
Ceylan pointed out that eye examination of eye tremor patients should be done in detail, “In the examination of these patients, the type of eye tremor, whether it decreases in the distance and near, the level of vision, the type of strabismus that accompanies it, the presence of zero point, and all eye structures from the cornea to the retina are evaluated.” he spoke.
Stating that the surgery should be planned according to the direction of the abnormal head position and the accompanying strabismus, Ceylan said that if there are disorders such as astigmatism, myopia or hypermetropia, it is appropriate to try using glasses or contact lenses before the surgery.
Prof. Dr. Ceylan stated that in cases accompanied by strabismus, surgical intervention is performed in the same session or gradually, and that a better visual comfort can be achieved with the improvement in the postoperative head position.
