This method provides – contactless and similar to sonography – high resolution and 3D imaging of the retinal layers in cross-sections. It allows for detection of pathological changes at an early stage and for a timely start of individual treatment.
This method is used for monitoring age-related macular degeneration, vessel occlusion, glaucoma and retinal disorders developed in context with diabetes.
With just one image acquisition, Optomap offers a panoramic view of more than 80% of the retina, compared to 10-15% obtained with conventional methods. This painless and contactless examination is carried out in seconds and usually does not involve dilation of the pupil, which makes it especially convenient and quite suitable for children. The examination results are ready to view instantly as high resolution and three-dimensional digital images.
By using this method, retinal alterations can be detected and documented and therapy can be adjusted accordingly. In some cases, dilation of the pupil complements with high resolution wide-angle photography, thus combining these two methods and benefitting from the advantages specific to each method.
The HRT is a painless and contactless method for a three-dimensional examination of the optic nerve head, involving the use of a laser and a scanner, and is used for early detection of glaucoma as well as monitoring glaucoma treatment. It is complementary to visual field analysis and provides important objective information.
Anyone suffering from dry eyes can benefit from a tear film assessment. There can be different reasons for dry eyes (sicca syndrome), e.g. reduced tear production, increased loss of tears and also environmental factors. A thorough examination of the tear film, the eye surface and the edges of the eye lids is followed by individual treatment.
This non-invasive, contactless method serves the detection of pathologic alterations by mapping an exact high resolution surface profile of the cornea. Corneal topography examination results enable the ophthalmologist to differentiate between harmless (e.g. astigmatism) and pathological alterations of the cornea (e.g. keratoconus). It is also an important tool in planning refractive surgery.
This non-invasive examination is used for detection of metabolic disorders within the retinal layer that provides the retina with nutrients (pigment epithelium). Early signs for conditions/ dysfunctions, e.g. for age-related macular degeneration, can be detected, even before other methods are able to detect irregularities. This allows for assessing a risk profile for development of the respective condition.
By testing the patient’s detection reaction regarding luminous stimuli of various intensities, loss of visual field can be measured objectively at an early stage. Visual field analysis is an important tool in diagnostics of glaucoma and needs to be performed regularly for monitoring of glaucoma progression. Perimetry can also provide important insights with regard to assessment of neurological issues.
Findings within both the anterior and posterior part of the eye can be captured and recorded objectively by means of high resolution digital photo-documentation, which creates a reliable basis for comparison of findings over time, and allows for timely decision making regarding treatment. Photo-documentation is recommended, for example, to assess birth marks of the ocular fundus, or small growths or tumours which cannot be classified instantly.
Pachymetry serves the measurement of the exact thickness of the cornea.
The corneal thickness differs from person to person.
Glaucoma patients need to undergo pachymetric examination in order to measure the intraocular pressure correctly and to be able to determine a treatment plan for each patient individually.
Pachymetry is also indispensable in deciding whether refractive surgery (e.g. Lasik) is possible or not.
The nyktometer measures a patient’s twilight vision and glare sensitivity under standardised lighting conditions (mesopic vision), and is performed without and with a standardised glare intensity. Nyktometer test results enable the ophthalmologist to determine whether these functions (twilight vision and glare sensitivity) lie within the normal limit or, respectively, within a certain range defined as safe. This examination is carried out particularly within the scope of medical reports and certificates.
