Fast, reliable screenings averaging 2 to 3 minutes. Screening requires just 5, 10 or 13 ft from the face to the display. Unique features include a standardized test by age group as recommended by the American Academy of Pediatric Ophthalmology and Strabismus which reduces errors and allows for conclusive screening. Easy to administer, the examiner simply presses correct or incorrect based on the child’s response.
Each pre-programmed protocol runs the same screening test each and every time thereby eliminating test-to-test inconsistencies, user bias, and administrative errors. The results of the screening are displayed on the screen for recording and/or recommending that the patient be referred to an eye-care professional.
Symbols and Letter Sets
The user can select peer-reviewed and calibrated LEA SYMBOLS, LEA NUMBERS, HOTV, Snellen Letters or the traditional Allen Pictures.
The protocol choices include:
- Critical Line - 5 letters/symbols determine if the child has the minimum “normal” acuity for a child of their age
- Single Crowded - 50% crowding bars around a single letter or symbol; useful for measuring acuity AND screening for amblyopia
- Mass Test - Crowds the critical line, combining the best features of the first two protocols in one easy and efficient format
- Threshold Test - A more thorough visual acuity test to determine the true visual acuity for each eye and can note two-line differences between the eyes (which should result in referral to an eye care professional)
