Background: The AAP vision screening guidelines are not uniformly delivered. Moderate amblyopia can be successfully treated in children 7 years of age and older. The ideal method and threshold of vision and/or acuity testing in school is not known.
Methods: 1700 students from first grade, kindergarten, and pre-kindergarten were screened with a flip-card, surround HOTV protocol with other eye patched combined with photoscreening; 234 students had "Gold Standard" confirmatory exams from which AAPOS standards were validated.
Results: Receiver Operator Curves were constructed by adjusting referral criteria by grade. A cutoff of 20/25 yielded fairly good (50%) sensitivity and 90% specificity for first grade and kindergarten, but many of the pre-kindergarten were unable to complete the testing.
Conclusion: Patched surround HOTV flip-card acuity is useful in starting school children and a cut-off of 20/25 passing acuity is suggested. Pre-kindergarten are not well acuity screened due to high inconclusive rate.

Background: A new, portable computerized distance vision testing (screen plus remote) system called VisionKeys has been developed by the missions equipment developer EyeMobil so we validated it compared to conventional research testing devices.
Methods: Using a standardized protocol of surround HOTV optotype presentation, the VisionKeys was compared to M&S for patched monocular distance visual acuity. A different VisionKeys function with anaglyph spectacle distance stereopsis was compared to near stereo on Titmus circles with Polaroid goggles and PDI Check on an autostereoscopic screen.

Background: The coronavirus (COVID-19) global pandemic has been a poignant reminder of the value of telehealth services to deliver care, especially as a means of reducing the risk of infectious disease transmission caused by close personal contact, decreasing unnecessary travel for medical consultations, and limiting the number of individuals in waiting rooms. The role of telehealth in ophthalmology has historically been limited to store-and-forwarding of images, much like what is used in radiology.
Patients And Methods: Remote evaluation using two-way audio-video communications over the initial 10-week period of clinic shutdowns.

Background: We needed to validate and calibrate our portable acuity screening tools so amblyopia could be detected quickly and effectively at school entry.
Methods: Spiral-bound flip cards and download pdf surround HOTV acuity test box with critical lines were combined with a matching card. Amblyopic patients performed critical line, then threshold acuity which was then compared to patched E-ETDRS acuity.

Crowding refers to the degradation of visual acuity for target optotypes with, versus without, surrounding features. Crowding is important clinically, however the effect of target-flanker spacing on acuity for symbols and pictures, compared to letters, has not been investigated. Five adults with corrected-to-normal vision had visual acuity measured for modified single target versions of Kay Pictures, Lea Symbols, HOTV and Cambridge Crowding Cards, tests.
