How do you take a picture with a slit lamp?

How do you take a picture with a slit lamp?

Steps

  1. Set up the patient at the slit lamp, instructing him or her to maintain fixation and stay as still as possible.
  2. Look through both eye pieces.
  3. Center the image and adjust the slit beam.
  4. Adjust the focus on subject matter.
  5. Determine which eye piece, right or left, will produce the best image to photograph.

How do you examine cornea with a slit lamp?

For examination of the cornea, the illumination arm should be shifted to a more oblique angle and narrow the beam. This will produce an optical cross section of the cornea, with partial reflection as the light passes through the tear film, epithelium, stroma, and Descemet’s membrane, and endothelium.

How do you check endothelium on a slit lamp?

The technique for viewing the endothelium involves using a slightly broadened slit beam and setting up the illumination system and microscope so the angle of incident light is equal to the angle of reflection.

How do you take a picture with a slit lamp on an iPhone?

Increase your zoom by tapping just above the camera icon that is at the very bottom and center of the screen or use the pinch-to-zoom feature. Zoom in until the image of the image fills the iPhone viewing screen. I recommend using a slit lamp magnification of 10x in order to maintain the best focus.

How do you take a picture of your retina?

Hold the camera 10 – 35 cm from the lens. Direct the camera along the patient’s pupillary axis. Aim the light to the pupil and find the retina glow. Direct the light through the lens onto the retina and continue video recording.

How do you check corneal endothelium?

The corneal endothelium can be viewed by specular reflection using a variety of instruments, such as contact or non-contact specular microscopes, confocal microscopes or slit lamp biomicroscopes.

What should I look for in a slit lamp?

Looking through the slit lamp, you should be able to see the red reflex, the beam should be traveling perfectly through the center of the pupil, and the iris should be in focus.

How do you focus a slit lamp without a focusing rod?

If the focussing rod is missing the slit beam should be positioned on the closed upper lid of the subject and then illumination system swung from side to side checking for parallax movement. Adjust the position of the illumination system until there is no parallax movement and then focus the eyepieces in turn.

What do you need to know about slit lamp?

A slit lamp exam can help diagnose the following conditions: macular degeneration, a chronic condition affecting the part of the eye that is responsible for central vision detached retina, a condition when the retina, which is an important layer of tissue at the back of the eye, becomes detached from its base cataracts, a clouding of the lens that negatively affects the ability to see images clearly

What is a slip lamp examination?

Slit Lamp Examination is the examination of the outer eye using a bright light focused into an elongated slit in combination with a biomicroscope.

What is the abbreviation for slit lamp examination?

How is Slit Lamp Examination (ophthalmology) abbreviated? SLE stands for Slit Lamp Examination (ophthalmology). SLE is defined as Slit Lamp Examination (ophthalmology) frequently.

Can a slit lamp exam detect glaucoma?

Yes, at the slit lamp we can do a variety of tests to detect glaucoma. We can measure pressures and perform an evaluation of the optic nerve and angle.
