Early AMD This is a case of early age-related macular degeneration (AMD). Anatomical changes in the regular fundus photograph demonstrate atrophic and RPE abnormalities consistent with the development of early AMD. The cross sectional OCT images also show anatomical changes associated with drusen formation.
Clinical Use of MAIA™ After multiple Expert Tests are performed MAIA tracks changes between subsequent tests to provide a graphic representation of the progression in average threshold, fixation stability and percent reduced thresholds, so that they can be monitored over time. A fundus image with the measured
Clinical Use of MAIA™ The Expert Test provides threshold visual field using a standard 4-2 staircase testing strategy and locates the preferential site of fixation. The average threshold is computed and a color-coded outcome provides a statistical comparison with the corresponding response from normal subjects. Fixation stability is presented
Clinical Use of MAIA™ MAIA™ uses 2 testing regimens to evaluate retinal threshold sensitivity. The Fast Test is used to assess whether a patient can perceive the luminance level seen by normal subjects (supra- threshold testing). Test points appearing in green indicate that the patient responded at normal level,
Evaluates macular threshold, fixation stability & their change over time. Any maculopathy, AMD, drug toxicity, amblyopia or unexplained vision loss Plots progression of macular threshold and fixation stability Evaluates the effect of external treatment regimens to macular threshold & fixation stability
MAIA is a non-mydriatic scanning laser ophthalmoscope which incorporates a high speed eye tracker and an automated macular perimeter to determine threshold sensitivity of the macular area and fixation characteristics and monitor these parameters in subsequent examinations. Any maculopathy from agerelated macular degeneration, amblyopia, glaucoma or unexplained vision loss can be evaluated
Patient uses ForeseeHome daily, in comfort of own home. Data automatically transmitted after each test through phone line. Notal Vision Data Monitoring Center (DMC) provides live, ongoing monitoring and will alert the doctor of important changes to schedule an appointment. The Doctor/practive can also access patient information and results through a secure website.
The 1st FDA-cleared ophthalmic home-based monitoring system was recently released. The best method for early detection is frequent monitoring (i.e. daily-weekly). It is impractical for patients to visit the eye care practice as frequently as needed. The most effective solution for early detection is home-based monitoring in addition to routine eye exams. Until
The Foresee PHP® Case Study An 80-year-old female presented blurred vision for two months in her left eye, with no clinical evidence of CNV present. The Foresee PHP test was performed, and the test result showed outside normal limits with a P-value less than 1%, and significant metamorphopsia. The
The Foresee PHP® How It Works When a dot-deviation signal is projected on a healthy retina, it stimulates a collinear set of retinal receptive fields. Special neuronal circuits in the visual cortex process this information, leading to the perception of a straight dot-deviation signal (Figure 1). When photoreceptors are displaced, both in the
