Zusammenfassung
Hintergrund: Im Rahmen der altersbezogenen Makuladegeneration (ARMD) können angiomatöse Proliferationen von der Retina aus in den subretinalen Raum einwachsen. Diese retinale angiomatöse Proliferation (RAP) kann man mit der Angiografie identifizieren. Wir haben in dieser Studie in ausgewählten Fällen eine fotodynamische Therapie (PDT) bei RAP durchgeführt. Methodik: Die Daten von 14 Patienten mit RAP, die mit PDT behandelt wurden, wurden retrospektiv nach einem standardisierten Protokoll ausgewertet. Das Protokoll umfasste den bestkorrigierten Visus (BCVA), eine binokulare ophthalmoskopische Untersuchung, Fundusfotografie, Fluoreszeinangiografie (FAG) und optische Kohärenztomografie (OCT). FAG und OCT Befunde wurden ausgewertet und in drei RAP-Stadien eingeteilt (RAP I: Intraretinale Neovaskularisation, RAP II: Subretinale Neovaskularisation mit retinoretinaler Anastomose oder subretinaler Neovaskularisation gegebenenfalls mit seröser Pigmentepithelabhebung, RAP III: Chorioidale Neovaskularisation gegebenenfalls mit vaskularisierter Pigmentepithelabheung). FAG und OCT Befunde wurden vor und nach der PDT nach dem standardisierten Protokoll untersucht und die Daten statistisch ausgewertet. Ergebnisse: Das Alter der Patienten lag zwischen 58 und 90 Jahren (Median: 76 Jahre). Bei 15 Augen von 14 Patienten mit RAP wurde eine PDT durchgeführt. Bei 6 dieser 15 Augen war nach der PDT die Makula trocken und ein Visusanstieg um ≥ 2 Zeilen feststellbar, 3 Augen davon mit RAP I und 3 mit RAP II. 4 Augen waren nach PDT stabil mit persistierendem Makulaödem und ± 1 Zeile, davon 2 RAP I, 1 RAP II und 1 RAP III. 5 Augen zeigten eine Zunahme des Makulaödems mit Visusverschlechterung um ≥ 2 Zeilen, davon 2 RAP I und 3 RAP III. Bei den erfolgreichen Behandlungen war der Median des BCVA vor der PDT 0,3, nach der PDT 0,6, bei den stabilen Fällen vor PDT 0,2 und nach PDT 0,2, in der Gruppe mit Verschlechterung der RAP prä-PDT 0,4 und post-PDT 0,01. Schlussfolgerung: Gemäß unserer Studie kann die PDT in ausgewählten Fällen erfolgreich bei der Behandlung des RAP Grades I und II bei ARMD Patienten sein. Weitere prospektive Studien sind notwendig, um die Effekte der fotodynamischen Therapie bei RAP zu validieren.
Abstract
Purpose: In age-related macular degeneration (ARMD) angiomatous proliferation can progress from the retina into the subretinal space. Retinal angiomatous proliferation (RAP) can be diagnosed by angiographic findings and optical coherence tomography (OCT). We investigated the outcome of photodynamic therapy in patients with RAP. Methods: 14 patients with ARMD and RAP were retrospectively analysed using a standardised protocol. The protocol included best corrected visual acuity (BCVA), ophthalmoscopy, OCT examination, fundus photography and fluorescein angiography (FAG). In a masked fashion the OCT and angiographic findings were independently graded in 3 stages (RAP I: intraretinal neovascularisation, RAP II: subretinal neovascularisation with a retinal-retinal anastomosis or subretinal neovascularisation with a serous pigment epithelial detachment, RAP III: choroidal neovascularisation with vascularised pigment epithelial detachment and retinal-choroidal anastomosis). 15 eyes of these 14 patients were evaluated pre- and post-PDT with the standardised protocol and the data statistically analysed. Results: The age ranged from 58 to 90 years (median 76 years). In 15 eyes of 14 patients with RAP a PDT was performed. 6 of these 15 PDT cases were successfully treated and gained ≥ 2 lines (dry macula), 3 eyes with RAP I and 3 with RAP II. 4 eyes stablilised with ± 1 line (persistent macular oedema) under PDT with 2 RAP I, 1 RAP II and 1 RAP III. 5 eyes showed a deterioration with loss of ≥ 2 lines (increasing macula oedema) with 2 RAP I and 3 RAP III. The median BCVA was pre-PDT in the successful cases 0.3, post-PDT 0.6, in the stable cases pre-PDT 0.2, post-PDT 0.2 and in the deterioration group pre-PDT 0.4 and post-PDT 0.01. Conclusions: According to our study PDT might be helpful in the treatment of RAP stages I and II in selected cases in ARMD patients. Further prospective studies are required to investigate the outcome of PDT in RAP.
