Occlusion dose monitor available for electronic recording of compliance in patch wearing for amblyopia.

The Occlusion Dose Monitor was first made by Allistair Fielder and Merrick Moseley in the early ninetees (Fielder et al., 1995) and miniaturized, following a suggestion by Paul van der Maas, the initiator of the RAMSES birth-cohort study on vision sceening (Groenewoud et al., 2010), by Cees Romijn and other electrotechnicians at the Academical Medical Center in Amsterdam in 1996 and 1997 (Simonsz, 1997). It can now be obtained, following a recent decision of the European Patent Office, in the following European countries: AL, AT, BA, BE, BG, CH, CS, CY, CZ, DE, DK, ES, EE, FI, FR, GB, GR, HR, HU, IE, IS, IT, LI, LT, LV, LU, MC, ME, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR. A series will be produced by collaboration of the Academical Medical Center and the Technical University Delft with a constructor of electronic compliance devices. Those interested in obtaining a series, for research on compliance with patch wearing in treatment for amblyopia, may send an inquiry and these will be forwarded to the manufacturer.
