Study shows smartphone ophthalmoscopy agrees with slit lamp biomicroscopy
Researchers found good agreement between smartphone ophthalmoscopy and slit lamp biomicroscopy when evaluating vertical cup-to-disc ratios in patients with ocular hypertension and primary open-angle glaucoma.
The comparative instrument study published in the Journal of Glaucoma included 110 patients with ocular hypertension or primary open-angle glaucoma. Vertical cup-to-disc ratio estimations were completed by undilated smartphone ophthalmoscopy (D-EYE, Padova, Italy) and slit-lamp biomicroscopy by two masked glaucoma specialists.
The differences between the mean vertical cup-to-disc ratio estimations obtained by the two methods were not statistically significant, according to researchers.
Overall exact agreement between the two modalities was found in 21 of 29 eyes in primary open-angle glaucoma patients and in 52 of 78 eyes in ocular hypertension patients, researchers said.
“Although optic nerve head examination is best performed through a dilated pupil, smartphone ophthalmoscopy is intended to serve as a tool to enable detection of disease in patients with poor access to ophthalmologic care,” the researchers wrote.
“The fast acquisition time per eye (12.8 seconds) could make the smartphone ophthalmoscopy a promising tool for glaucoma assessment in community screening programs, even by nonophthalmic personnel exploiting the wireless connectivity of smartphone in a telemedicine scenario,” the researchers concluded. – by Abigail Sutton
