The OculoCAM photo system is a comprehensive portable photo system that can produce high quality images of all external eye pathology including full face photos, anterior segment photos, and photos taken through the slit-lamp ocular. Video sequences can be taken externally and through the ocular as well. Components of the system include:
|1. The Plate-Splidle Bracket and Camera Support Arm
2. The Plastic Camera-Ring Light Connector
3. The 24 LED Ring Light
4. The Occular Attachment for the Haag-Streit 900 Slit Lamp
5. The Universal Ocular Attachment
6. The Single LED Side Light
7. Extra, 9 Volt Battery for the Ring Light
8. Extra 3M Dual-Lock Tape in Camera Compartment
9. The Luggage-Style Fitted Hard Case
This arm connects the camera-light assembly to the slit-lamp carriage via an adjustable plate-spindle bracket. The arrangement adds a third arm to the Haag-Streit type slit-lamp’s vertical column, allowing the camera to substitute for the slit-lamp’s microscope for the purpose of taking photos.
In the second generation OculoCAM system, two ocular attachments are provided to accommodate the greatest number of slit lamp models. The original mount is designed to be attached to the chrome ring of the removable 10X ocular.
The Universal, ‘T-bolt’ stainless steel ring clamp, can be placed on the ocular itself or the knurled ring behind it, depending on the slit lamp model. With either device, the camera should be moved away from the ocular after the photo is taken to avoid striking the ocular when the lens barrel retracts.
Adjust the slit beam to light the subject either directly (corneal lesion such as dentritic Keratopathy or cellular ingrowth in a flap) or with the red reflex (posterior subcapsular cataract, asteroid, capsule clouding, toric lenses etc.). It is also possible to take gonio views with this set up or to take video of things like IOL movement or pupil abnormalities.
The cold LED ring light allows the camera to be brought close to the patient’s face without discomfort and the slide adjustment permits the camera to be positioned for slit beam employment when desired. Multiple settings allow for varying levels of light. When using this light source, the camera can be pulled back using the slide and slit lamp carriage for full face photography or rotated to the side for profile views. The LED ring light is useful where changes in the surface structure of the cornea are revealed by distortion of the Purkinje image of the ring. Therefore, pterygiums, corneal grafts and injuries often show best with this illumination.
Corneal surface phenomenon will sometimes be obliterated by direct illumination from the ring light. Sometimes the slit beam can be directed behind the lesion so that it is illuminated in profile such as a corneal foreign body, corneal dystrophies or blood vessels in the cornea.
This single white LED light has a flexible cable that can be clipped to the headband or face shield of the slit lamp and extended to the eye to be photographed. Usually it is positioned below the eye and close to the cheek. Alone, it will light many corneal lesions and is very easy to use.
Not infrequently a combination of light sources will produce the best results. Often the slit beam will work best when there is general illumination from the ring light or external single LED light to avoid extreme contrast. The slit beam can be used to light the pathology directly, or can be placed on the iris behind the lesion for back-lighting. The beam should be kept just wide enough to show detail.
Choosing a Camera
The OculoCAM photography system includes all of the components above, providing a stable, efficient means for taking photographs and video. It does not include a camera. Because camera models are continuously changing, and because we did not want to promote a specific product or brand, we have chosen to leave the choice of camera up to the user. We realize many users may already own a camera or have personal preferences as well. However, after having used the system for countless hours with multiple cameras of various types and brands, we believe a few models are superior for use with this system.
