Which Photoscreener is for You?

Compare9 Comparison data Early objective vision screening can reduce amblyopia blindness. The photoscreening CPT code, 99174, is finally recognized by many insurers so pediatric care-givers should consider which Photoscreener is Ideal for their program. A few vendors have objective pediatric vision screeners commercially available. ABCD has published some vision screen FAVORITES. Video Demonstration.

Vision Screening
compareVideo Video Demonstration PlusoptiX: German made and extensively validated, infrared, multiplanar, with immediate computer interpretation by user-selected, age-dependent referral criteria. Handheld, portable camera model s-12 replaces the former models that required cable to computer (S09 with Linux), separate monitor and printer/labels. Sound directed fixation and focal distance. Quick. Purchase or Lease options.  
ABCD Clinics
iScreen: hand-held camera with simple screen and keyboard. This battery powered, portable unit evolved from the validated, table-top unit retaining excellent fixation mechanism. Internet image transfer with Memphis experienced Reading Center. Lease with per-image fee.

  SPOT by Pediavision; new introduction from company with former experience as Plusoptix vendor. Portable, infrared photoscreener with internal interpretation and attached monitor. Preliminary validation encouraging. Lease option.  
  Welch Allyn Suresight: This is a remote autorefractor using [photo] light beyond visible spectrum and wave-front analysis. Monocular screen with sound-directed focal distance. Sturdy and fairly simple to aim with few buttons. Internally validated by VIPS with less robust predictive value in subsequent comparisons with MTI community screening, therefore more false positives.  
  Retinomax: this is a proximal (less than 5 cm) hand-held autorefractor, with keratometry option, that attempts to relax accommodation with internal camera image. Validated in VIPS and used in MEPEDS and BPEDS NIH large-scare studies. Expensive and not as useful for children less than 3-4 years old.  
  Rebiscan (PVS): in development by Drs David Hunter and David Guyton. Hand-held featuring foveal birefringence to detect ocular alignment. Soon to be commercially available. Twitter  
  MTI: no longer commercially available camera and Polaroid film (can use Fuji FP-300B with revamped old MTI) with extensive validation but requiring experienced image reading to achieve desired validity.  
  EyeDx: original computer-interpreted, digital cameral photoscreener- by David Granet- no longer available.  
  ADBC: commercial, digital flash cameras with close flash-to-lens distance- small, quick, quirky to focus at times, needs red-eye redux override, needs local interpretation such as DCC. Relatively inexpensive. iPhone option. Few still available on E-Bay.  
  GoCheckKids: iPhone app developed by Gobiquity to override the automatic redeye redux preflash and acquire orthogonal images for interpretation.  
  2WIN: Made in Italy, this remote autorefractor has modifiable referral criteria allowing it to work as a photoscreener.
