No CommentsFundoscopy
In the fundoscopy test, the fundus is examined. ย With a special device (called a fundus endoscope), the doctor looks through the pupil of the eye at the retina, the optic nerve, the retinal blood vessels and the inner cavity of the eye. ย The retina forms the back of the eyeball. In fact, this is the only place in the body where blood vessels can be seen as they are.
ย How to take the test
ย With the question of Dr. Muhammad Hantira, an honorary assistant professor, the Eye Department, Umm Al-Qura University, Saudi Arabia
ย Explain that the eyeball can be seen directly or indirectly.
ย In the first method, the doctor looks with an ophthalmoscope that lights the retina directly or through a crack lamp. ย In the first method, the doctor places a mirror on his head that reflects light inside the retina and looks at the inside of the eyeball, using a magnifying lens.
With the help of this examination, which lasts about 5-10 minutes, it is possible to see damage to the eye itself, or to notice systemic diseases that also appear in the retina.
ย Warnings
ย โข Public
ย There are no risks.
ย โข During pregnancy:
ย There are no special effects or problems.
ย โข Breast feeding:
ย There are no special effects or problems.
ย โข Babies and children
ย There are no problems or special effects. ย The patient’s cooperation is needed, and so the examination may be difficult. ย When examining young children and infants to assess the need for glasses or to diagnose strabismus, the examination should be performed when the pupils are dilated. ย Sometimes, a stronger distillation of a substance (such as cyclopentolate or atropine) is needed in young children. ย Some of the children have red cheeks, fever, rash, or a rapid pulse.
In rare cases – drowsiness or hyperactivity, sometimes even convulsions.
ย โข Elderly:
ย There are no special effects or problems.
ย โข Driving:
ย The subject may suffer from blurred vision and dazzling that lasts for several hours after the examination, as a result of the dilated pupil.
ย Medicines that affect the test result
ย Medicines that affect the autonomic nervous system, such as adrenaline, atropine, beta-blockers and others, may cause a permanent change in the size of the pupil, but they do not affect the retina. ย Therefore, some of these drugs may also make it difficult to perform the test, but they do not affect the results.
