For whom and why are eye examinations important?
At CM, we provide eye examinations for both adults and children. Patients usually look for an eye doctor (ophthalmologist) when they suffer from chronic or acute complications. Preventive examinations are also important with patients who do not have any problems but their family health history includes eye-related diseases. These can include strabismus (being cross-eyed), amlyopia (lazy eye) and refractive defects with higher diopter values found in relatives of the child. In such cases, it is advised that the children are first examined between the ages of 6-12 months.
It must be stated that people who use contact lenses have to undergo examinations of the anterior segment of the eyes. Adults older that 40 should undergo preventive eye examinations primarily as a means of early glaucoma detection. In case when glaucoma was present within family medical history, the patient should undergo this examination sooner than that. Early diagnosis, detection and effective treatment can prevent irreversible eye damage or loss of sight. Last but not least, patients with high blood pressure, diabetes and other complex diseases should undergo regular eye examinations as many of these diseases manifest themselves through various eye-related diagnoses.
For an eye doctor, what are the most common complications that adult patients arrive with?
The most frequent type of complications include declining distance/near visual acuity, redness in the eyes, watering, burning or cutting sensation, mucus or purulent secretions from the eyes, swelling of the eyelids, dull eye pain, double-vision and other related problems. With pediatric patients, the most common problem includes strabismus (being cross-eyed) requiring a visit to an eye doctor. Many patients arrive to an eye doctor following a recommendation from another specialist, because they are suffering from another complex illness that often has eye-related complications as well.
What is the examination like and how long does it take?
During a basic eye exam, we try to identify the patient’s medical history by asking specific questions concerning the time period from when he/she has been experiencing eye complications, whether the patient had eye problems in the past, his/her complex illnesses, current usage of medication, history of disease in the family and various allergies. We also examine the refraction by determining the best correctable distance/near visual acuity. Further we evaluate color vision, measure intraocular pressure and with the help of slit lamp, we examine the anterior segment of the eye along with the interior (fundus). The examination lasts anywhere between 30-45 minutes.
What equipment do you have available at CM?
Naturally, we already have LCD optotypes and trial lens kits with frames as well as an automatic refractometer (device for measuring spherical and cylindrical refractive errors), a contact-less tonometer (device to measure intraocular pressure) and a slit lamp (special microscopic device that allows for an optical “cut” through the eye to evaluate a suspected problem in detail). With the help of the Volk Super Field lens, we can use the slit lamp to also evaluate the eye interior (fundus). However, for that to be possible, the patient must cooperate well.
Our pediatric patients are usually examined using a direct or indirect ophthalmoscope. Near vision acuity is measured using Jaeger eye charts. We also test for color vision as well as using the Amsler grid test in patients whose retina is affected at the point of sharpest vision (in the macula). Where required, we carry out examinations of the anterior chamber drainage angle (gonioscopy) as well as analyze the visual field – using computer aided perimetry tests.
With the help of additional test, we look at the quality or quantity of the tear film. When a patient arrives with excessive tearing (watering of the eye), we can carry out a flush of the lacrimal passages. In case we locate a foreign body in the cornea or conjunctiva, we can remove it using specialized tools under topical anesthesia.
Are surgical procedures performed at CM?
Yes, CM houses a surgery room where we can carry out small surgeries of the skin on the eyelids such as removing small growths or chalazions. Whenever deemed necessary, samples of the tissue are further sent for a specialized histological examination.
With serious complications, is it possible to seek specialized follow-up care at another facility – for example for a surgical procedure?
If further specialized procedures such as laser surgery or intraocular surgery is required, we cooperate with renowned facilities capable of providing our clients with superior medical care. At our clinic, we will provide the initial consultation when for example considering laser eye surgery or surgical refractive procedures to address various diopter issues.
