Background Due to the many restrictions imposed during the COVID-19 emergency, the normal clinical activities have been stopped abruptly in view of limiting the circulation of the virus. The extraordinary containment measures have had a dramatic impact on the undertaking and follow-up of ophthalmic outpatients. Objective In order to guarantee proper monitoring and routine care, the Pediatric Ophthalmology equipe of Rovereto Hospital (North-East of Italy) supported by the Competence Center on Digital Health TrentinoSalute4.0, designed and implemented a digital platform, TreC Oculistica, enabling teleophthalmology. We report our innovative—albeit restricted—experience aiming at testing and maximizing the efficacy of remote ophthalmic and orthoptic visits. Methods A multidisciplinary team created the TreC Oculistica platform and defined a teleophthalmology protocol. The system consists of a clinician web interface and a patient mobile application. Clinicians can prescribe outpatients with the App and some preliminary measurements to be self-collected before the televisit. The App conveys the clinician’s requests (i.e. measurements) and eases the share of the collected information in a secure digital environment, promoting a new health care workflow. Results Four clinicians took part in the testing phase (2 ophthalmologists and 2 orthoptists) and recruited 37 patients (mostly pediatric) in 3 months. Thanks to a continuous feedback between the testing and the technical implementation, it has been possible to identify pros and cons of the implemented functionalities, considering possible improvements. Digital solutions such as TreC Oculistica advance the digitalization of the Italian health care system, promoting a structured and effective reorganization of the workload supported by digital systems. Conclusions The study tested an innovative digital solution in the teleophthalmology context and represented the first experience within the Italian healthcare system. This solution opens up new possibilities and scenarios that can be effective not only during the pandemic, but also in the traditional management of public health services.

Purpose This study aims to describe the TreC Oculistica novel smartphone App that facilitated the clinical practice of pediatric ophthalmology and strabismus during the COVID-19 pandemic and to report on the validation of visual acuity tests in a home setting. Methods The Trec Oculistica smartphone App was prescribed to eligible patients at the Pediatric Ophthalmology and Strabismus Clinic, Ophthalmology Unit of Rovereto Hospital between September 2020 and March 2022. Four key indicators were identified for monitoring visual and visuo-motor functions remotely: visual acuity, ocular motility, head posture, and color vision. Clinicians selected few mobile applications (iOS, Android) and printable materials within the Trec Oculistica App: the Snellen Chart Visual Acuity App, the 9Gaze App, the eyeTilt App, the Color Blind test App, the LEA Symbols pdf, and the Snellen Chart pdf. All patients, aged 4 and older, were screened at home for visual acuity at 3 meters and later in the clinic (LEA Symbols cabinet or Snellen computerized optotype).The 9Gaze, the eyeTilt, and the Color Blind test Apps were only recommended to a subset of patients based on clinical suspicion or diagnosis. The Wilcoxon signed rank sum test and Weighted Cohen's kappa coefficient were applied to compare pairs of scores from different settings. Results The Trec Oculistica App was downloaded and activated by 97 patients or their caregiver. 40 patients were tested at home using the 9Gaze App, 7 used the eyeTilt App, and 11 used the Color-Blind test App. Families reported that all the Apps were easy and intuitive to use; clinicians reported that measurements were reliable. 82 eyes of 41 patients (mean age 5.2 years, SD ± 0.4, range 4.4-6.1) were tested for visual acuity using the self-administered LEA Symbols pdf . 92 eyes of 46 patients (mean age 11.6 years, SD ± 5.2, range 6-35) were evaluated using the self-administered Snellen Chart Visual Acuity App or the Snellen Chart pdf. Home median visual acuity score was statistically different from that registered in clinical setting for both the LEA Symbols pdf (P-value 0.0074) and the Snellen Chart App and pdf (P-value 0.0001). The strength of agreement was 0.12 (slight) for the LEA Symbols pdf, 0.50 (moderate) for the Snellen Chart Visual Acuity App, and 0.69 (substantial) for the Snellen Chart pdf. Conclusions The novel TreC Oculistica smartphone App was a useful tool for facilitating the clinical practice of pediatric ophthalmology and strabismus during the COVID-19 pandemic. In the follow-up of strabismus patients and patients with suspected inherited retinal diseases, the 9Gaze, eyeTilt, and Color Blind test applications were deemed to be intuitive and easy to use by families, and were considered reliable by clinicians. In a home setting, visual acuity tested by means of Snellen Charts was moderately congruent with the in-office examination. On the contrary, agreement was poor in younger children tested with the LEA Symbols pdf.
