Fundus photographs are ocular documentation that record the appearance of a patient's retina. Optometrists, ophthalmologists, orthoptists and other trained medical professionals use fundus photography for monitoring the progression of certain eye condition/diseases.
The idea that fundus can and should correspond to a combining form fundo-drives the formation of an alternate form, fundoscopy (fundo-+ -scopy), which is the subject of a descriptive-versus-prescriptive difference in acceptance.
A fundus photo, showing the optic disc as a bright area on the right where blood vessels converge. The spot to the left of the centre is the macula.The grey, more diffuse spot in the centre is a shadow artifact.
Fluorescein angiography [1] (FA), fluorescent angiography (FAG), or fundus fluorescein angiography (FFA) is a technique for examining the circulation of the retina and choroid (parts of the fundus) using a fluorescent dye and a specialized camera.
The most common agents used to dilate the pupil are phenylephrine (2.5% in pediatrics or 10% in adults) and tropicamide (0.5% or 1%). While phenylephrine stimulates receptors that contract the dilator muscle of the pupil, [6] tropicamide blocks stimulation of the pupillary sphincter muscle to allow for relaxation. [7]
Sample text Head "NC/AT" or "Normocephalic, atraumatic" Eyes: ophthalmoscope "EOM intact, PERRLA, anicteric, no injection, fundus WNL (within normal limits), no papilledema" Ears: otoscope "TM intact, noninflamed" Nose: otoscope "No congestion" Throat: otoscope "Oropharynx WNL" or "no erythema or exudate" Mouth: otoscope
There are two techniques used to assess the red reflex listed below. Both are noninvasive, inexpensive, and quick. Dilation of the eyes is unnecessary and not recommended due to the theoretical but rarely seen risks of sympathomimetics and antimuscarinic systemic effects – tachycardia (fast heart rate), hypertension (high blood pressure), and arrhythmia (abnormal heart rhythm).
