This document describes an orthoptic instrument called a haploscope. A haploscope is an optical device that presents different images to each eye, allowing examination of binocular vision. The haploscope described has adjustable components to measure fusion, stereopsis, deviations in different gazes, and more. It can be used for both diagnostic and therapeutic purposes in orthoptic treatment and management of conditions like strabismus and amblyopia.

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

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
