| Summary: |
Accurate diagnosis of
age-related macular degeneration (AMD) is required for
appropriate qualification for the treatment. There are
some useful simple subjective techniques but a numerous
of diagnostic methods utilize advanced and complicated
technology. Fluorescein angiography (FA), indocyanine
green angiography (ICGA) and optical coherent tomography
(OCT) are presumed as the most essential in AMD
evaluation. FA allows for detection of CNV and for
taking a decision of PDT application. All of these
methods are useful in qualification for PDT re-treatment.
ICGA is a valuable tool in assessment of occult CNV, OCT
helps to differentiate leakage from CNV and
fibrovascular tissue staining. There are some new
methods used for AMD evaluation. Multifocal
electroretinography provides good information of central
retinal function. It allows objectively monitoring
retinal function changes after PDT treatment.
Preferential Hyperacuity Perimetry (PHP) helps to
quantify macular lesions and to evaluate metamorphopsia.
It uses a dot visual signal (hiperacuity stimuli) for
quantification of a macular area function. Currently
used diagnostic methods commonly utilize digital
electronics technology which allow to share and discuss
difficult cases among medical community located even
worldwide. With advance of new modern treatment
modalities, new diagnostic tests especially those which
allow for early diagnosis and those which have a good
correlation with quality of patient life are needed. |
