ROUTINE OPHTHALMOLOGY CONSULTATION Measurement of the visual acuity – the ability of the eye to see an object of a certain size, placed at a specific distance.
Aerial image simulation is used in order to establish the best optical correction method for near and far-sighted visions.
It allows informing the patient regarding the maximum level of visual acuity to be reached.
Test – Nonverbal test
REFRACTION MEASUREMENT (the total refractive power of the eye) is performed with the help of:
AUTO KERATO-REFRACTOMETER (corneal curvature and diopters automated measurement)
The latest technology of PLUSOPTIX VISION SCREENING for children of 3 months old and older !
Detects and prevents the risk of amblyopia in children. Clinically approved.
Amblyopia is a disorder of the eyesight which can lead to permanent loss of vision.
It is impossible to correct by using contact lenses or eyeglasses. Amblyopia is caused by untreated dysfunctions of the eyesight, like: refraction errors, strabismus and ocular pathologies.
Studies conducted in industrialized countries indicate that 25% of children of pre-school ages have undetected vision disorders, which is not uncommon. The visual acuity tests and monocular measurements, as well as the tests using auto refractometers are not able to detect anisometropia (different refractive errors in both eyes). 80% of the information received by children within their first 12 years of life is of visual nature. Dysfunctions of the vision and the possible subsequent amblyopia can prevent the child from getting good results in school, from practicing sports, it reduces the safety level when crossing the street, etc.
Good vision is extremely important during one’s lifetime. Adults receive 70% of the total information via their vision. The earlier the eyesight disorders are detected and treated, the easier it is to get a normal vision and prevent amblyopia. Ideally, vision disorders should be detected and treated before the age of 2. Plusoptix binocular device easily and correctly detects refractive errors, as well as anisometropia, starting with 3 months of age. Also, it detects anisocoria and fixation disparity (strabismus).
Subjective refraction is an aerial image simulation performed in order to establish the best visual acuity by using the phoropter, which contains different lenses, the examiner being able to change these lenses by computerized command.
Measurement of the ocular tension – a non-contact tonometer is used for detecting ocular hypertonia.
Slit lamp biomicroscopy allows the examination of the anterior segment of the eye (eyelids, conjunctiva, cornea, sclera, anterior chamber, lens).
Ophthalmoscopy allows the visualization of the retina, of the optic nerve, choroid and blood vessels.
Specific Ophthalmologic Consultation
Corneal topography
A map of the corneal surface curvature is created, detecting issues related to the quality of vision and corneal health. This technique can detect astigmatism, degeneration of the cornea (Keratoconus). When preparing the patients for refractive surgery and conducting a follow-up post surgery, it is useful to choose the correct daily contact lenses.
Non-invasive, non-contact investigation of the quality and quantity of the tear film through corneal topography
The analysis of the quality and quantity is important in the dry eye diagnosis, prescription of treatment, screening of candidates for LASIK and choosing the contact lenses. Only an intact tear film guarantees optimal comfort when using contact lenses!
- Tear break up time (TBUT) test;
- The tear (lacrimal) meniscus height.
Corneal Pachymetry – the process of measuring the thickness of the cornea and correcting the intraocular pressure;
Computerized perimeter is the most modern method for assessing the visual field. This method helps in providing a diagnosis for ophthalmologic, as well as neurologic pathologies. The contribution of this method for correct diagnosing is that it detects the small defects in cases of
cortex and optic tract diseases, which is not possible when only using manual routine methods, the latter ones being able to only highlight obvious defects.
Computerized perimeter offers the following advantages:
· It gives more precise results, because it is a static method;
· It eliminates the subjectivity of the examiner;
· It allows the perfect monitoring of the fixation;
· It allows the possibility to automatically re-evaluate the abnormalities;
· It comprises a variety of programs for testing the visual field of the ophthalmologic pathologies, like glaucoma, diseases of the optic nerve and retina, as well as neurological pathologies, like multiple sclerosis, cerebral hemorrhages with different bleeding locations, cerebral tumors (pituitary adenoma, craniopharyngioma, meningioma, glioma), tumor-like parasitic lesions (Cysticercosis, Echinococcosis) or infectious lesions (tuberculoma, osteoma), pituitary abscesses, trauma, aneurisms, paranasal sinus mucoceles, empty sella syndrome, toxic optic neuropathy, arachnoid cysts, optochiasmatic arachnoiditis, meningitis.
OCULAR ULTRASOUND
Ocular ultrasound is used for the examination of the ocular structures, particularly when direct visualization is obscured by cataracts, for example, which makes the lens opaque. It also allows measuring the size of the eyeball and studying the different structures of the orbit, especially the optic nerve and the extra ocular muscles. The ocular ultrasound is painless and does not present side effects. The ultrasounds are not dangerous for the eyes and the results can be observed on the spot.
