Adaptations are described that allow the slit-lamp to be used to document squint disorders. Changes are made in the observation system, illumination system, for recording clinical findings and visualisation of clinical findings. The author includes the use of minus lens in front of the slit-lamp objective to obtain a sharp image of both eyes. The narrowed angle between illuminated and observed axis is minimised by holding a 14D prism horizontally in front of the slit-lamp to illuminate the patient’s face and central corneal reflexes. Recording of results is by digital record. Documentation of results is by Microsoft Powerpoint.
