User Instructions

LED turns ON and OFF with the button on OptiCard. LED is attached to the edge of the card . Below LED, there is an aperture for direct fundoscopy. OptiCard may be used with the cell phone camera or retinal examination may be done with naked eye.

Proper Dilation of pupils will give the best results.
As with the use of any other diagnostic instrument, the liability of usage of this device and patients’ safety remains the responsibility of physician.


Technique to use with naked eye:

As the button is moved Up LED turns ON. Patient’s pupil (dilated already with a mydriatic drug) is examined through the aperture of the OptiCard. From a distance of half meter(or closer) red reflex may be seen. Bring the card closer to eye till retinal vessels are visualized and follow them converging to the optic disc. (Fundus is visualized much easily with OptiCard than with traditional direct ophthalmoscope, as the distance between aperture-lightsource-observer’s eye is negligibly small(2mm) as compared to traditional Direct Opthalmoscope where this distance is (>10mm) and hence slight rotation of hand causes light rays to misalign with observer’s eye.)


Technique to use with a cell phone :

To view fundus through a cell phone the upper border of the card (with LED on its edge) is placed close to the cell phone camera aligning it to the center of the camera lens. OptiCard is turned-ON and Camera is turned on in the cell phone and by seeing on LCD , LED is adjusted such that it is just visible through the cell phone LCD (see video at www.tlabs.pk). The card may then be secured on the cell phone using sticking tape. Turn-OFF OptiCard. Focus the phone camera to some distant object about 6 feet away. Then turn-ON OptiCard ,and see through patients pupil. (Do not yet zoom) Once fundus/retina is visualized properly, then you can zoom. To use card with a zoomed camera ,it needs good practice. From half a meter distance a dilated pupil is visualized that may show a red reflex on Phone LCD.  Cell phone camera is brought closer to the eye, about an inch away from it and retinal vessels get visualized which may be followed towards the center to visualize the disc. Video or still images may be taken . 

DO NOT LET CONTACT with eye happen.

Due to advancement in AUTOFOCUS technology of camera, Camera lens is able to focus retina in almost every patient so OptiCard gives good results. OptiCard is a must have gadget for physicians to make diagnoses of Retinal haemorrhage, papilledema ,etc in ER or to PHOTO-Follow the retinal changes in hypertension or diabetes, to monitor via photos the progression of disease over time !

With practice , fundus and retina may be explored through undilated pupils also.
Proper Dilation of pupils will give the best results.
If the OptiCard is attached to silicone cover of cellphone , the cover may be simply detached from the phone , and attached again once needed .
