Abstract

Purpose : To determine the effectiveness of remote tele-glaucoma compared to clinical direct observation in retinal imaging and through-put time.

Methods : Prospective comparative pilot trial of 30 patients (242 Fundus and 102 Optical Coherence Tomography (OCT) images) screened through the remote tele-glaucoma screening protocol and via the conventional clinical evaluation. Parameters studied included comparisons of through-put (measured as the time from technician review to patient departure), tonometry, ocular examination and particularly optic nerve evaluation (estimation of vertical and horizontal cup-to-disc ratio). Opacity SuppressionTM (OS) software was applied post-capture to enhance image assessment when opacities precluded retina and optic nerve head (ONH) evaluation. Peripapillary and nerve fiber layer (NFL) detail were assessed post-OS on a scale of 1-3 (1=similar, 2=improved, 3=significant improvement) and graded independently by 2 readers. Inter-observer agreement between the two arms (tele-glaucoma and physical presence) were determined.

Results : A strong positive Pearson correlation was observed for a) intraocular pressure of right eye (OD), left eye (OS) (0.92, 0.81) and b) optic nerve cup/disc ratio OD, OS (0.83, 0.87). (Table 1) Although tele-glaucoma had lower accuracy in providing cup/disc ratios (82%) vs. clinical exam (91%), the Opacity Suppression software applied to images improved visualization of peripapillary detail in 70% and 82% of assessed images by grader 1 and 2, respectively. NFL visualization was also improved but to a lesser extent (33% and 50% by grader 1 and 2, respectively). When compared to tele-glaucoma, the conventional clinical exam assessment was 40 minutes longer and required 3 examiners as opposed to a 20-minute through-put in tele-glaucoma and 1 examiner.

Conclusions : Tele-glaucoma provided comprehensive evaluations (tonometry, ocular anterior and posterior segment/optic nerve imaging) that strongly correlated with conventional face-to-face clinical evaluation. Although conventional clinical exam was superior to tele-glaucoma in evaluating the optic nerve C/D ratios, tele-glaucoma proved an efficient mean of patient time and was better with OCT applications for NFL and peripapillary distribution.
