ZusammenfassungHintergrund: Fundusautofluoreszenz ist eine neue Technik, welche die Verteilung von Lipofuszin am Augenhintergrund darstellt und dadurch eine Beurteilung des Zustands des RPE ermoglicht. Ziel unserer Untersuchung ist es, die diagnostischen Moglichkeiten von OCT RTvue wie auch von Autofluoreszenz in der Beurteilung der Entwicklung der trockenen AMD zu untersuchen.Material und Methoden: Es wurden in diese prospektive Studie 37 AMD-Patienten einbezogen: 22 mit trockener Form von AMD mit Drusen und 15 mit Drusen und geografischer Atrophie. Die Patienten wurden nach dem allgemeingultigen Verfahren inklusive OCT und Autofluoreszenz untersucht. In allen Fallen wurden die Programme: HD Line, Cross Line, EMM5 am OCT RTVue Background and Purpose: Fundus autofluorescence is a novel technique that gives us information about the RPE cells by evaluating the distribution of lipofuscin in the retina. The purpose of our study was to evaluate the diagnostic abilities of OCT, RTVue and fundus autofluorescence in predicting the progression of dry AMD.Material and Methods: In our study 37 dry AMD patients were enrolled: 22 of them with druses and 15 with developed geographic atrophy. They all underwent complete ophthalmological examinations including OCT and autofluorescence. We used the RTVue OCT programmes HD line, Cross line, EMM5 and EMM5 progression in all cases. The autofluorescence was recorded with the help of the Canon CX1 fundus camera.Results: OCT images in the AMD patients with dry AMD and large druses showed typical undulations in the RPE/choroid line and occasionally drusenoid detachment of the RPE. Autofluorescence showed different patterns. The confluent reticular autofluorescence was associated with the development of neovascular membranes. In geographic atrophy patient OCTs showed diminished retinal thickness measured with EMM5. On autofluorescence the findings at the border zone atrophic/normal retina were of particular importance. The diffuse increased autofluorescence in that area was considered to be a sign for further atrophy progression.Conclusion: Our results point out that OCT in combination with autofluorescence is important in following the progression of dry AMD. Pathological autofluorescence at the border of atrophic lesions is an important sign for disease activity. Although both OCT and autofluorescence visualise the changes in RPE, autofluorescence is of key importance in predicting the development of the disease.
