Synoptophore Instructions

2. Intended Use The fundamental parts of the Synoptophore are two independently movable sight tubes. With the instrument set at zero (sight lines parallel) the two images, superimposed, will be seen as one integrated figure by a subject with normal binocular vision. A subject with strabismus, divergent or convergent, will only see a superimposed (fused) figure with ease, when the sight tubes are set at an angle to each other (angle of deviation). The muscles are exercised by looking through the tubes at the deviation angle and moving them laterally in unison, so that the subject scans left and right alternatively. Single eye exercise can be given by gradually changing the angle between the sight tubes whilst the subject maintains fusion for as long as possible.

! Warning:

To avoid risk of electric shock, this equipment must only be connected to a mains supply with protective earth.

Synoptophore Instructions

The following instructions are intended to assist the user to become rapidly familiar with the various controls of the Synoptophore. Although some brief references to the orthoptic usage of the instrument have been given, it is obviously beyond the scope of this manual to detail the precise methods of examination and treatment of which the Synoptophore is capable. The figures in brackets on this description refer to the illustrations of the particular model 2001, 2002 or 2003 pages 12, 13 & 14.

Please Note:

The HB Motor should not be run continuously. Please switch off between patients.

4. To remove the instrument from the packing case and subsequent handling. !

Lift Synoptophore by handles (101), NOT by the optical tubes.

5. Connection to electricity supply (a.c. only). Check the voltage of your electrical supply and ensure that the voltage selector (126, p12) corresponds to this. Switch the instrument on at (124, rocker switch) and check that the green indicator lamp is working.

6. Adjusting the Synoptophore to the patient. (a) Free the optical tubes by releasing the central lock (122) and the two tube locks (121) which should be turned inwards. (b) Set the selector switch (131) to ‘NORMAL’. (c) Measure the patient’s interpupillary distance and and set the pointer on the scale (103) accordingly, by means of the controls (102). (d) Adjust the height of the chinrest (105) by means of control (104). (e) Adjust the projection of the chinrest, by sliding it toward or away from the patient, so that the patient’s eyes are as close as possible to the eye pieces. (f) Adjust the projection of the forehead rest (106, p12) to accord with (e) above. (g) Set all the pointers at zero:Pointers on horizontal deviation scales (109, p12) by means of handles (108, p12). Pointers on vertical deviation scales (111) by means of controls (110). Pointers on torsional deviation scales (112) by means of controls (113). Pointers on elevation and depression scales (114) by means of controls (115).

7. Measuring the angle alpha. The angle alpha is the angle between the optic axis of the eye and the visual axis. Often this can be large enough to give the appearance of a squint or to mask a squint and therefore it should be assessed. In fact it cannot be measured, but a close approximation can be made by using the special slide A15 which is available. Place the slide in either one of the slide carriers (116) and instruct the patient to look at the zero mark. Observe the reflection of the light on the patient’s cornea and if this is not in the centre of the pupil the patient is told to look at successive numbers, or letters, until the reflection is in the centre. Adjoining letters and numbers are separated by one degree, thus if the patient is fixing on ‘E’ when the corneal reflex is central, the angle alpha can be recorded as 5˚. It is positive when nasal, and negative when temporal, and the sign, too, must be recorded. Having measured one eye, then the same procedure should be carried out with the other eye fixing.

8. Measuring the objective angle. If possible, the objective angle of deviation should be measured with each eye in turn fixing. A pair of slides from the simultaneous perception range is used of a size large enough to be seen clearly but small enough to ensure fixation on a central point. The patient is instructed to look at the slides and the tubes are then converged or diverged by the operator until the corneal reflections are seen to be central. One light is extinguished by depressing one of the two flashing switches (129) and the patient is told to concentrate on the picture still illuminated. On being satisfied that fixation is accurate the light for that eye is extinguished at the same time as the light before the other eye is turned on. The non-fixing eye is then observed and any movement to take up fixation is compensated for by converging or diverging the tube. Vertical movements will also be noted and the tube moved correspondingly by the appropriate vertical deviation control (110). The patient is then told to fix the picture as before and the procedure is repeated until there is no further movement of the non-fixing eye when it takes up fixation. The angle obtained is the objective angle. The examination is now repeated with the other eye fixing. Similar measurements will be made with the patient looking 15˚ to the left, 15˚ to the right, 15˚ up and 15˚ down (the last two by using the elevation and depression controls (115)). In cases where there is poor fixation in one eye the measurements will be made with the good eye fixing only, and the tubes will be moved until the corneal reflections are in the centre of the pupils.

Synoptophore Instructions

9. The subjective angle and abnormal retinal correspondence. The subjective angle is found by instructing the patient to move the handles (108) himself until the two pictures are superimposed. If this angle is the same as the objective angle, when small pictures are used, the retinal correspondence is normal. If, however, the angles differ, the retinal correspondence is abnormal and the difference between the two is the angle of anomaly. These measurements are made with the patient’s prescribed correction; the appropriate lenses are fitted into lens holders (118). The patient is then measured without corrective lenses.

10. Side movements. Lateral movements are valuable as a test of fusion and as an orthoptic exercise. With a pair of slides from the fusion range in the slide carriers and the tubes set at an angle of deviation, the two tube locking controls (121) are turned outwards. The central lock (122) must be released. The tubes are then moved side to side and the patient is instructed to follow the movements of the pictures.

11. Vergences. Horizontal vergences are measured on the scale (119) which is engraved ‘ADD’ (Adduction - the uniocular movement of the eye horizontally INwards) and ‘ABD’ (Abduction - the uniocular movement of the eye horizontally OUTwards). Set the tubes at the angle of deviation and the scale (119) at whichever zero mark is appropriate. A pair of fusion slides must be used in the slide carriers. Tighten the two tube locking controls (121) and engage the central lock (122). Slowly rotate one or both controls (121) whereupon the tubes will be converged or diverged, according to the requirements. The angle through which fusional vergence is held by the patient is indicated on scale (119) and the point where the pictures ‘break’, fusion is no longer maintained. Vertical vergences are measured by rotating one or other of the elevation and depression controls (115). In both cases the corneal reflections should be kept under observation.

12. Heterophoria. Examination and measurement of cyclophoria is possible with the Synoptophore by means of the rotating slide carriers operated by controls (113). Each carrier rotates 20˚ on either side of zero. The phoria is indicated on scales (112). Hyperphoria is measured on scales (110) in prism dioptres, for the slide carriers move tangentially up and down by the action of controls (111).

13. Dimming rheostats. A rotary rheostat is in circuit with each of the 6V. slide illumination lamps. By means of the controls (130) these rheostats reduce the intensity of the light as required. In certain post-operative cases it is desirable to lesson the light reaching the patient’s eye, whilst when treating amblyopes it may be necessary to reduce the illumination in front of the good eye and maintain the maximum light in front of the amblyopic eye.

14. Hand flashing switches. The two buttons (129) operate micro-switches, one of which is in circuit with each of the 6V. lamps. One use has already been described in section 5. A further use is to stimulate a suppressing eye by rapid flashing.

15. Auxiliary lens holders. The two lens holders (118) fitted into the eyepieces are used to carry additional lenses, when required.

16. Slide ejectors. The slide ejectors (117) can be used to make the slides ‘jump’ and therefore stimulate a suppressing eye.

17. Promoting an after-image (Models 2001and 2002 only).

The after-image device consists of two high intensity light sources each containing a 12V. lamp and a condensing lens. Supplied with the Synoptophore are two special slides, S.3 and S.4, one consisting of a vertical white slit, with a red central fixation point on a black background and the other a horizontal slit also with red spot. These slides are inserted into the carriers with the matt surface inwards, i.e. towards the patient. The opal defusing screens must be swivelled downwards out of the optical pathway by rotating the black plastic control levers (123) situated immediately below the latch of the lamphousing. This allows more light to pass through the slide and thus a stronger after-image is produced. The selector switch (131) is turned clockwise to the first position ‘R’, and the mains switch (124) is turned on. Instruct the patient to fix the red spot and ensure that his fixation remains steady for a period of some 7 to 10 seconds. Turn the selector switch clockwise to the next stop, which is an ‘off’ position, remove the right eye slide and swivel back the diffusing screen. Then turn the selector switch clockwise to the next position ‘L’ and ask the patient to fix the red spot for the prescribed time. Finally, turn the switch still further to one of the ‘off’ positions, whilst you remove the left eye slide and swivel back the diffusing screen.

Synoptophore Instructions

An after-image is maintained more easily when the background is alternating light and dark, therefore the automatic flashing unit should be used immediately after the patient has been subjected to the above. This is done simply by rotating still further the selector switch until the stop marked ‘Both eyes’ is reached. If normal retinal correspondence exists, the patient will now see an after-image in the form of a cross + but if the retinal correspondence is abnormal the after-image may be a variant of one or other of the following: I- or -l. The result should be given graphically and the images labelled accordingly to the eye concerned.

18. The automatic flashing unit (Models 2001 and 2002 only).

The unit is fitted to Synoptophore Models 2001 and 2002. The same unit is used on both instruments. From paragraph 14 above, you will have understood that the flashing unit will only operate the 6V lamps when the selector switch (131) is turned to one of the three automatic flashing positions (red engraving). The three positions are ‘Both eyes’ ‘Left eye and ‘Right eye’. If both eyes are to be flashed, for the purpose of maintaining an after-image, the switch (133) can be set at Simultaneous or at Alternating. If only one eye is being flashed, it makes no difference what position the switch is in. The speed of the flash, or to put it another way, the length of the light and the dark phase, is variable. The fastest flashing (shortest phases) is obtained when switch (132) is set at ‘Rapid’. In that position the light and dark periods are of equal length. To make the flashing slower, switch (137) is moved to the ‘Variable’ position and the two controls (134) are now in circuit. One of these controls determines the length of the light phase and the other determines the length of the dark phase. The engraved figures surrounding these two controls do not represent actual lengths of time of the phase. However, the high figures do indicate long phases and the low figures short phases. If, therefore, a slow flash (long phases) is required, with light and dark of equal length, the controls would be set at ‘10’. When set at ‘0’, the phases would be short; when at ’5’, medium, and so on. If the relationship between light and dark is required to be unequal, then the two controls would be set as different figures. A little experimentation will soon show what a great variety of flashing can be obtained. Although the figures are empirical, they are of value in as much as they allow the operator to preset the device. Moreover, it may be found that a patient retains an after-image longer with a certain light/dark relationship. The figures can thus be recorded for future use.

19. Haidinger’s Brushes (2001 Model only).

Haidinger’s brushes are phenomena caused by polarised light falling upon the macula. As the centre of the brush coincides with the fovea, the use of the phenomenon is indicated in cases of eccentric fixation and abnormal retinal correspondence, for the patient, when he has learned to recognise the brush, can then be made aware of the spatial projection of the fovea and use this point for fixation. The device in Synoptophore Model 2001 consists of two motorised units (138) which are inserted into the slots in the optical tubes adjacent to the slide carriers, when the brushes are required. At other times the motor units are housed in the special compartments of the instrument table. In addition to the removable parts, the Synoptophore itself has certain other built-in features which are necessary for Haidinger’s brush treatment. These are the iris diaphragms (140), the high intensity light switches (130) and the slots in the tubes to take additional blue filters at (139). Haidinger’s brushes can be presented to the patient’s left eye, right eye both eyes together. They can be used with after-image or with ordinary slides or with both after-images and slides. Special slides in black and white, on transparent film are available, and are better than coloured slides, for this purpose. The motor unit (138) or units are inserted into the slots adjacent to the slide carriers (see illustration). The On/Off switches (135) on the control unit are turned on and the motors then commence to rotate the polaroid discs. Each motor unit has its own speed control (137) and each has its own reversing switch (136). Some patients will see the brushes more easily than others and the speed of rotation may have some bearing on this. The reversing switches are useful as a test to ensure that the brush is really being observed. The purpose of the iris diaphragms (140) is to reduce the field of vision and to test whethter a patient who superimposes the Haidinger’s brush and the target really fixes centrally or not. If superimposition remains when the aperture is at its smallest, the patient must be viewing the target with the fovea. If a patient who otherwise sees the brush and target fails to do so at the smallest aperture setting fixation is not foveal. If the Haidinger’s brush is presented to one eye only, it is necessary to place a blue filter into the slot (139) before the other eye, so that two eyes are ‘balanced’. If the filter is not inserted, the white light will dominate the blue.

Synoptophore Instructions

20. Changing the lamps and fuse. It is Important that only the correct voltage and wattage lamps are used, otherwise the flashing unit may be damaged. A protective fuse (141) of the cartridge type is fitted on the push and turn principle. Models 2001 and 2002 each contain two 6V lamps and two 12V quartz-halogen lamps. Model 2003 contains two 6V lamps only. The 6V lamps are the slide illuminators and the 12V lamps provide the illumination for promoting after-images and Haidinger’s brushes. To exchange a 6V lamp, open lamphousing (127) and unscrew the faulty lamp (turn anticlockwise). The plastic bulb holder can be drawn from its supporting slide to facilitate lamp removal. To exchange a 12V lamp hold the glass with a soft cloth and ease the lamp carefully upwards.

Warning: The quartz-halogen 12V lamp must never be touched with uncovered fingers.

Service and Maintenance Service and maintenance should only be carried out by one of the following: The manufacturer’s service personnel, Recommended agents or Qualified persons authorised by Clement Clarke Ophthalmic. Technical Manual A Technical Manual (part no. 1902076) containing maintenance information and wiring diagrams etc. for 2000 series Synoptophores, is avaliable from Haag-Streit UK Limited.

Synoptophore Instructions

21. Cleaning The device does not need to be disinfected. Contact of cleaners/disinfectants with lens may cause irreversible damage and should be avoided. The Synoptophore and accessories can, if required, be wiped down with ready-for-use, disposable 70% ethanol disinfectant wipes between patients to avoid crossinfection. Surface wipes are also permitted, including Clinell Universal wipes. When an instrument is returned for service and repair, the device must be wiped down as stated, prior to packaging. When cleaning, particular attention should be shown to the following: Forehead rest (106), Chinrest (105), Handles for adjustment of horizontal angle (108) and Breathshield (107). Scope of action Non-immersion manual cleaning methods are appropriate for low risk items (those items that come into contact with intact skin or do not contact the patient) where soaking in aqueous solutions, e.g. electrical and electronic equipment, will compromise the device. Alcohol wipes should be used to clean electrical contacts on equipment (avoid contact with plastic parts or enclosures as alcohol is a solvent). Equipment required • A warm water/detergent solution at correct dilution. • A clean, disposable, absorbent, non-shedding cloth for application of detergent solution. • A clean, disposable, absorbent, lint-free cloth. • An appropriate chemical neutraliser, first aid kit and eyewash bottle, in case of splashing with detergent. Procedure If the item is electrical; ensure that it is disconnected from the mains supply before commencing the cleaning procedure.

Commencing with the upper surface of the item, wipe thoroughly ensuring that detergent solution does not enter electrical components. Periodically rinse the cloth in clean water and repeat the above steps. Surfaces should be carefully hand-dried using a cloth. Note: Non-immersion, manual cleaning is not a disinfection process, but where an alcohol wipe is used to dry surfaces, this may have a disinfecting effect. Safely dispose of cleaning materials and alcohol wipes, if used. Monitoring and Control • Staff training • Physical application • Nature of soil • Accessibility of cleaner to item/part of equipment • Detergent concentration

Safety precautions • Always wear protective waterproof clothing, robust gloves and eye protection if splashing is likely to occur. • After removing protective clothing, wash and dry hands thoroughly. • Avoid splashing. Precautions should be taken when using alcohol, as it is flammable. The ‘pooling’ of alcohol on equipment should be avoided and alcohol evaporation ensured, if necessary by forced air-drying. Care should also be taken to ensure that alcohol does not enter the item e.g. via ventilation slots. The above was written with reference to; Sterilization, Disinfection and cleaning of Medical Devices & Equipment: Guidance on Decontamination from the Microbiology Advisory Committee to the Department of Health Medical Devices Agency (MAC manual section 2 page 20 updated April 2005)

Make sure that the device/lamps have cooled down before cleaninng. Wearing protective clothing, immerse the cleaning cloth in the detergent solution and wring thoroughly.

23. EMC Declaration

The Waste Electrical and Electronic Equipment Directive (WEEE Directive) aims to minimise the impact of electrical and electronic goods on the environment, by increasing re-use and recycling and reducing the amount of WEEE going to landfill. It seeks to achieve this by making producers responsible for financing the collection, treatment, and recovery of waste electrical equipment, and by obliging distributors to allow consumers to return their waste equipment free of charge.

With the increased number of electronic devices such as PC’s and mobiles, medical devices in use may be susceptible to electromagnetic interference from these devices. Which may result in incorrect operation of the medical device and create a potentially unsafe situation. Medical devices should also not interfere with other devices. In order to regulate the requirements for EMC with the aim to prevent unsafe product situations, the EN606011-2 standard has been implemented. This standard defines the levels of immunity to electromagnetic interferences as well as maximum levels of electromagnetic emissions for medical devices. Medical devices manufactured by Haag-Streit UK Ltd conform to this EN60601-1-2 standard for both immunity and emissions. Nevertheless, special precautions need to be observed:

Haag Streit UK Ltd is a producer of Electrical & Electronic goods therefore we have registered our business with the Government Environment Agency through a registered compliance scheme. Scheme operator : Valpakweee Compliance Valpak Ltd Stratford Business Park Banbury Road Stratford-upon-Avon CV37 7GW Producers Number:
