Figure shows schematically the technique with the automatic switchoff algorithm for three differently pigmented fundus places, so as to obtain uniform lesions. The shutoff mechanism for subvisible or barely visible lesions is determined by a characteristic curve that correlates the induced temperature over time with a particular lesion size. The characteristic curve to get a probability to make visible lesions from the preferred size (expected dose ED) was determined previously The characteristic curve was fitted working with the damage integral in the Arrhenius theory, which describes the connection between thermal denaturation of proteins more than time as well as the temperature course,, by stepwise time integration over the expected denaturation or damage, respectively.

The pixeltomicrometer scale was lmpixel. If only a single observer recognized a particular lesion, it was classified invisible (diameter), otherwise the imply diameter was utilized as an estimate in the genuine spot size. Comparing the three measurements, we excluded outofrange values as defined previously. We chose that system to be able to rule out any observerdependency and bias inside the assessment of faint andor poorly outlined fundus lesions.Figure . Schematic diagram of an arbitrary TTC curve. The Arrhenius theory supplies a mathematical model on the timedependent tissue effect of a temperature improve, and served as a supply for our empirically adapted TTC curves. All timetemperature combinations that meet 1 specific TTC curve will induce equal lesions. Brief exposures demand greater temperatures than lengthy exposures in order to reach an equal effect (if T . T, then t , t). Vertical transposition of your TTC plot allows modifying lesion intensities.OCT AnalysisOCT pictures were acquired right after hours, week, and months. We scanned the treated area in lm steps employing a spectraldomain OCT (HRA OCT Spectralis; Heidelberg Engineering, Heidelberg, Germany). We averaged Bscans per sectional image and traced each and every lesion via consecutive OCT series utilizing the AutoRescan function. The greatest linear diameter (GLD) of a lesion 
was measured within the proprietary computer software of your OCT machine. We measured the GLD at the photoreceptor inner segmenttoouter segment junction line or, if this measurement was not unequivocal, in the RPE level. Each sectional image that showed a lesion was completely reviewed, and the widest diameter passing through the lesion was measured as GLD. As a way to assess the burn intensity of every single lesion, we graded lesions on hour OCT photos according to a sevenstage classifier that we had validated and published separately. Characteristics of these intensity classes are reviewed in Figure . Lesion intensity might be referred to by the term “OCT class.”fit enabled us to calculate the ED temperature thresholds for arbitrary exposure times.

Figure shows schematically the method of your automatic switchoff algorithm for 3 differently pigmented fundus locations, so as to attain uniform lesions. The shutoff mechanism for subvisible or barely visible lesions is based on a characteristic curve that correlates the induced temperature more than time with a particular lesion size.
