According to the World Health Organization, more than 180 million people in the world suffer from some form of visual illness. Detect these ocular pathologies in time is very important to be able to give a suitable treatment to each patient that avoids future complications and even blindness that could be avoidable.
From the Service of Ophthalmology of the Vithas Xanit International Hospital, led by Dr. Cilveti, recommend the realization of at least one annual ophthalmologic examination that include ophthalmology tests oriented to the characteristics of each patient.
Purpose of ophthalmologic examinations
The purpose of eye examinations is to provide guidance to the specialist to know if the patient needs glasses or not, if he can have a glaucoma or vision problem more important, since like we do annual breast reviews, allergy reviews or other examinations, the sight also needs your periodic care.
More frequent ophthalmologic examinations:
- Determination of visual acuity: to know the degree of vision of the patient, determining the smallest letters that can read from a special table at 6 meters distance. Perhaps it is the best known among the population.
- Measurement of automatic refraction of the eye: to quickly detect if the patient has any optical defect. Depending on the problem you have, you can correct it with glasses, lenses or refractive surgery. The ophthalmologist uses a special device called a refractor through which the patient looks while focusing on an optometric table also located at 5 meters. This device contains lenses of different strengths that are changed and placed in sight until the patient sees clearly.
- Measurement of intraocular pressure: for monitoring glaucoma, a determinant of blindness. An apparatus called tonometry is used, which can be non-contact or contact (touch the cornea with the tonometer and the measurement is performed after the use of anesthetic drops in each eye, so the test is painless).
- Amsler grid test: is based on the use of a template where a central point between squares appears. The patient is placed at the distance indicated by the ophthalmologist and, following his indications, performs the test, which helps to determine whether or not there is alteration in the macula of the eye, which allows to diagnose pathologies such as macular degeneration, which is usually associated to age and that has become the main cause of blindness above the 55 years.
With these simple ophthalmology tests our specialist can evaluate the condition of our vision and offer solutions tailored to each patient.
