For Eye Care Professionals

Reduce chair time and enhance diagnostic skills with unique Opsis features and test strategies.

Test Strategy	Targets		Method	Clinical significance
Reversed contrast and blue free background			Compare acuities, retinal pigment disorders and macular edema often score 2 lines better with reversed contrast	Cone /rod disorders, functionally, patients scoring higher with reversed contrast may benefit from blue filtering lenses
20/200 and 20/200 letter contrast sensitivity (Pelli Robson/MARS)			The large size reduces affect of acuity and refractive error in a similar  fashion of MARS and Pelli Robson	Low contrast sensitivity may indicate retinal edema with AMD, DR or retinal tears with PVD. Sensitive for patients with reduced acuity of any etiology.
Spatial frequency contrast sensitivity			Random generation of targets in 5 sine wave frequencies (1.5..18 cpd) with auto record and graphing	Manage and monitor refractive surgery patients and retinal pathologies with sine gratings sensitive to logCS0.02
Mesopic contrast sensitivity		A new and innovative test to assess the dark adaptation and contrast sensitivity under mesopic conditions (background luminance of 3cd/m2). Measures the just noticeable difference of luminance.		Assists in the differential diagnosis and functional vision of individuals with retinal pigment disorders
Random, forced  choice stereopsis Howard Dolman			Howard Dolman simulation random forced choice method  with interlaced targets for  improved clinical accuracy	Sensitive to 20" , strategies include use in a dark or light room
Amsler grid and color vision screening			Adjustable size and reverse contrast, color vision screening is randomly generated	Adjust grid to correspond with acuity, color isolates deutanomaly  and protanomaly
Adjustable Mallet box (James Sheedy)			Additional fusion locks and adjustable disparity enhance response	Measure fixation disparity to assess sensitivity of the observer
Retinoscopy target			Random character presentation at 20/400 with low luminance (cartoon for children)	Maintain fixation for accurate static retinoscopy, the low luminance reduces reflections
Fixation target			Customize the size to match the acuity	the animation assists with accurate cover test for strabismus and phoria assessment
Fusion and Suppression			Worth dot and suppression tests are designed for both light and dark rooms	Size adjustable for  varying acuities
Advanced and improved astigmatism assessment			Astigmatism detection targets are rotatable, the X-Cyl test combines acuity and is size adjustable	Improved power and axis determination and its faster.
ETDRS + AO			Choose the preferred strategy, 10% contrast too for occupational screening	Better comparison with pre-existing records with AO strategy if needed
