Utility and Feasibility of Teleophthalmology Using a Smartphone-Based Ophthalmic Camera in Screening Camps in Nepal.
Article in Asia-Pacific journal of ophthalmology (Philadelphia, Pa.). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo determine whether use of a mobile device-based ophthalmic camera by ophthalmic technicians (OTs) in village screening camps in Nepal followed by remote image interpretation by an ophthalmologist can improve detection of ocular pathology and medical decision-making.
designEvaluation of mobile device-based ophthalmic camera through study of before and after clinical decision-making.
methodsOne hundred forty patients over 18 years of age presenting to remote screening camps with best-corrected visual acuity ≤20/60 in one or both eyes were enrolled. Participants were examined by an OT with direct ophthalmoscopy. The technician recorded a diagnosis for each eye and a disposition for each patient. Patients then had anterior segment and fundus photos and/or videos taken using a smartphone-based ophthalmic camera system. Photos and videos were uploaded to a secure, HIPAA-compliant, cloud-based server, and interpreted by masked ophthalmologists from XXX, who independently recorded diagnoses and a disposition for each patient.
resultsThe diagnoses given by OTs and ophthalmologists differed in 42.4% of eyes. Diagnosis agreement was highest for cataract [k = 0.732, 95% confidence interval (CI) 0.65-0.81], but much lower for posterior segment (retina/optic nerve) pathology (k = 0.057, 95% CI -0.03-0.14). Ophthalmologists and OTs suggested different dispositions for 68.6% of patients. Agreement was highest for cataract extraction (k = 0.623, 95% CI 0.49-0.75), whereas agreement for referral to XXX was lower (k = 0.12, 95% CI 0.00-0.24).
conclusionsRemote ophthalmologist consultation utilizing a mobile device ophthalmic camera system is logistically feasible, easily scalable, and capable of capturing high-quality images in the setting of rural eye screening camps. Although OTs are well equipped to identify and triage anterior segment pathology, this technology may be helpful in the detection of and referral for posterior segment pathology.
