Eye tests for humans should be interpreted by human eyes too.

Only iScreen uses certified ophthalmic professionals to verify the results of every photoscreening. While our competitors depend entirely on automated software to analyze images — leading to over-referrals and avoidable errors — iScreen takes it a step further to ensure greater accuracy and quality control. After our artificial intelligence performs an initial analysis on the image, an expert iScreen analyst reviews it with a trained eye. iScreen’s analysts are leaders in their field and quite literally wrote the book on ophthalmic assisting. With experience examining tens of thousands of photoscreening images every year, our analysts give every image the attention it deserves.

If accuracy is important to you, choose iScreen.

The accuracy of vision screening devices depends on two measures: sensitivity and specificity. Sensitivity measures the percentage of children screened who had amblyopia risk factors and were accurately referred to an eyecare specialist. Specificity measures the percentage of children with normal vision who were accurately identified as not needing to see a specialist. Our high-performing vision screener excels in both categories. Using our method, parents and their children do not waste time and energy with unnecessary trips to an ophthalmologist or optometrist, and the eye care professionals can focus their attention on the children who really need it.

Because of our leading technology, off-site expert analysis and quality control, iScreen outperformed its top competitors in both sensitivity and specificity, taking into account inconclusive results, according to a peer-reveiwed study by a leading pediatric ophthalmologist published in the Journal of Pediatric Ophthalmology and Strabismus. 1

The Difference Is Clear

When pediatricians using iScreen refer their patients to pediatric ophthalmologists, those referrals are far more likely to actually need treatment than referrals from pediatricians using competitive devices, according to a separate 2021 peer-reviewed study published in American Association for Pediatric Ophthalmology and Strabismus.2 In that study, iScreen Vision referrals had a positive predictive value (PPV) of 64.3 percent, compared to just 26.8 percent for its next closest competitor. Put more simply, that means 2 out of every 3 patients who were referred by our customers really had a problem that needed treatment. Referrals from pediatricians using the competition were only correct for 1 out every 4 or 5 patients. 2

What Other Studies Say About iScreen And Pediatric Vision Screening

“One patient had isolated small (1 mm) cataract and had inconclusive PlusOptiX, passed SPOT, but was referred by iScreen and GoCheckKids. … Some (particularly the iScreen) stimulate fixation and have a fast shutter that allows image capture in children with diminished attentiveness.”

—Journal of Pediatric Ophthalmology and Strabismus3

“The only screening device with a PPV >50% was the iScreen. PPV is a useful metric, because it enables referring providers to guide patients on a post-screening plan and to choose devices that minimize over-referral… The iScreen also detected conditions such as cataracts, anisocoria, eyelid abnormalities, esotropia, exotropia, hypertropia, and amblyogenic astigmatism.”

—Journal of American Association for Pediatric Ophthalmology and Strabismus4

“The digital iScreen Vision screener 3000, updated from a previous analog device, presents a quick and reproducible method for screening children.”

—Journal of American Association for Pediatric Ophthalmology and Strabismus5

“Our data suggests that the iScreen device may be useful in a high-risk population of developmentally-at-risk preschool children for detecting amblyogenic such as refractive errors, constant strabismus, and media opacities.”

—American Orthoptic Journal6

“iScreen is easy to focus in a very-dark room (big pupils), takes the quickest image capture of all photoscreeners (better for noncooperative children) and relies on central, expert reader interpretation.”

—Journal of American Association for Pediatric Ophthalmology and Strabismus7

“Many cases of amblyopia escape detection without effective screening… Early identification and treatment of risk factors for amblyopia enables prevention of amblyopia. Diagnosis and treatment of amblyopia at an earlier age may lead to a better and more stable final visual result, with shorter treatment times, more rapid improvement in visual acuity, and better overall compliance with treatment regimens.”

—Journal of American Association for Pediatric Ophthalmology and Strabismus8
