RESUMO
Background: The aim of this study was to describe the value of the Odysight® application in addition to a classical follow-up regimen in the detection of exudative recurrences in patients with macular edema. Methods: We conducted an observational, multicenter, retrospective study. The Odysight® application includes a visual acuity (VA) test that can lead to alerts in case of a drop of >5 VA letters on two successive tests. The efficacy of the alerts in detecting exudative recurrence was studied. Results: A total of 149 eyes of 123 patients were included. The sensitivity of alerts for the detection of recurrence was 30.8% (95% CI [17.6; 44.0]) and its specificity was 83.7% (95% CI [73.2; 94.3]. A better baseline VA was found to be significantly associated with a better retention of the application (OR = 0.05, 95% CI [0.002; 0.62]; p = 0.045). Of the 12/39 alerts that detected a recurrence, eight (20.5% of all alerts) resulted in the scheduling or advancement of an intravitreal injection. Conclusions: In the present study, the sensitivity and positive predictive value of the Odysight® application seems low but its use in addition to the usual follow-up of the patient can detect, in certain cases, an early recurrence and thus allow an anticipated readjustment of the treatment.
