Smartphone fundoscopy with 20 dioptres lens: our experience

Abstract

Objective: Assessment of the utility of smartphone fundoscopy in diagnosing posterior pole pathologies. Methods: An iPhone 12 and a 20D Volk lens were used for smartphone fundoscopy. Patients needing bedside consultation were examined with direct ophthalmoscopy and smartphone fundoscopy. Some patients were examined with this technique after slit lamp examination. Results: Over one year 23 bedside fundus examinations were performed and 2 papilledema were diagnosed. After initial slit lamp examination, photos of various pathologies were taken: age-related macular degeneration, branch retinal artery occlusion, arterial embolus, branch retinal vein occlusion, non-arteritic anterior ischemic optic neuropathy, myelinated retinal nerve fiber layer, choroidal naevus. Discussion: With the 20D lens, the image is overturned, magnified 3,13X, and the field of view is 46°. The utility was demonstrated in literature by teaching students this technique and using it in screening for retinopathy of prematurity. The weighted retinal irradiance was measured in two studies. It was 4,6 mW/cm2 in one and from 0,58 to 2,30 mW/cm2 in the other, within safe limits. Conclusions: Smartphone fundoscopy is a fast, accessible, and safe technique for fundus examinations. Other departments could use it for the diagnosis of papilledema.
