AIMS: To estimate disease progression based on analysis of macular volume measured by spectral-domain optical coherence tomography (SD-OCT) in patients affected by Stargardt macular dystrophy (STGD1) and to evaluate the influence of software errors on these measurements.

METHODS: 58 eyes of 29 STGD1 patients were included. Numbers and types of algorithm errors were recorded and manually corrected. In a subgroup of 36 eyes of 18 patients with at least two examinations over time, total macular volume (TMV) and volumes of all nine Early Treatment of Diabetic Retinopathy Study (ETDRS) subfields were obtained. Random effects models were used to estimate the rate of change per year for the population, and empirical Bayes slopes were used to estimate yearly decline in TMV for individual eyes.

RESULTS: 6958 single B-scans from 190 macular cube scans were analysed. 2360 (33.9\%) showed algorithm errors. Mean observation period for follow-up data was 15 months (range 3-40). The median (IQR) change in TMV using the empirical Bayes estimates for the individual eyes was -0.103 (-0.145, -0.059) mm per year. The mean ({\textpm}SD) TMV was 6.321{\textpm}1.000 mm at baseline, and rate of decline was -0.118 mm per year (p=0.003). Yearly mean volume change was -0.004 mm in the central subfield (mean baseline=0.128 mm), -0.032 mm in the inner (mean baseline=1.484 mm) and -0.079 mm in the outer ETDRS subfields (mean baseline=5.206 mm).

CONCLUSIONS: SD-OCT measurements allow monitoring the decline in retinal volume in STGD1; however, they require significant manual correction of software errors.

PURPOSE: To compare grading results between short-wavelength reduced-illuminance and conventional autofluorescence imaging in Stargardt macular dystrophy.

DESIGN: Reliability study.

METHODS: setting: Moorfields Eye Hospital, London (United Kingdom).

PATIENTS: Eighteen patients (18 eyes) with Stargardt macular dystrophy.

OBSERVATION PROCEDURES: A series of 3 fundus autofluorescence images using 3 different acquisition parameters on a custom-patched device were obtained: (1) 25\% laser power and total sensitivity 87; (2) 25\% laser power and freely adjusted sensitivity; and (3) 100\% laser power and freely adjusted total sensitivity (conventional). The total area of 2 hypoautofluorescent lesion types (definitely decreased autofluorescence and poorly demarcated questionably decreased autofluorescence) was measured.

MAIN OUTCOME MEASURES: Agreement in grading between the 3 imaging methods was assessed by kappa coefficients (κ) and intraclass correlation coefficients.

RESULTS: The mean {\textpm} standard deviation area for images acquired with 25\% laser power and freely adjusted total sensitivity was 2.04 {\textpm} 1.87~mm(2) for definitely decreased autofluorescence (n~= 15) and 1.86 {\textpm} 2.14~mm(2) for poorly demarcated questionably decreased autofluorescence (n~= 12). The intraclass correlation coefficient (95\% confidence interval) was 0.964 (0.929, 0.999) for definitely decreased autofluorescence and 0.268 (0.000, 0.730) for poorly demarcated questionably decreased autofluorescence.

CONCLUSIONS: Short-wavelength reduced-illuminance and conventional fundus autofluorescence imaging showed good concordance in assessing areas of definitely decreased autofluorescence. However, there was significantly higher variability between imaging modalities for assessing areas~of poorly demarcated questionably decreased autofluorescence.
