Synoptophore

1. OPTOM FASLU MUHAMMED

2.  ORTHOPTIC instrument
 It’s a Haploscopic device..?????

3.  A haploscope is an optical device for
presenting one image to one eye and
another image to the other eye.
Greek origin-
haploieides- single
Skopeo- to view.

5. MirrorEyepiece(+6.50DS)
Slide carrier
Diffusing screen
Iris diaphram

6. Base
 the transformer
 voltage selector
 on,off switch
 switches of other additions

7. Low voltage lamps
-illumination of slides
High voltage bulbs
-afterimage creation
- Haidinger brushes

8.  head & chin rest
 Handles
- PD adjustment
-measuring horizontal angles
 central lock
-vergence exercise
 vertical deviation controls.
 Depression controls
-angle of deviation in different
direction of gaze

9. Grades of Binocular Vision
 Simultaneous Macular Perception
-parafoveal ,
 Fusion
 Stereopsis

11. Various varieties availableVarious varieties available

13. Various varieties availableVarious varieties available

15. Various varieties available

16.  Maddox test slides- white
 After image,H.Brushes- blue
 Orange slides- SMP

18.  entoptic phenomena
 Operated by 2 on/off switches,2 speed
control & 2 reversing switches
 active polarized light falling on macula
 eccentric fixation & ARC

19.  blue filters are inserted in the slot.
 An iris diaphragm restricts field of vision
to stimulate target point

20. Therapeutic uses
Diagnostic uses

21.  Measurement of range of fusion
(H ,V &T)
 Assessment of binocular status(SMP,F&Ste)
 Measurement of IPD
 “After Image” testing
 To detect Retinal Correspondance
 Measurement of deviation (SA&OA)
 Appreciation of entoptic phenomena


22.  Pt’ is seated c chin & forehead adjusted so
that eye is at the level of eye piece
 The IPD is adjusted c the fixing eye aligned
c line on top of eyepieces

23.  Adjustment in position of tubes are
done for vertical, horizontal and
torsional deviations
 For measuring deviations
-SMP slides are used.
-In subj.measurement pt’ decides &
in obj. examiner does so, by
switching on or off the light

24.  For measuring fusion
-tubes are locked after neutralisation
of deviation.
-Convergence & Divergence are
induced till patient sees binocular
single.
- BREAK POINT & RECOVERY POINT

25.  Fusion Vergence exercises
 Management of suppression-
antisuppression exercises
 eccentric fixation & ARC
 Amblyopia therapy using
H.brushes
