outside the arcades
Retinal tears
Lattice degeneration
Localized retinal detachments
Any eye requiring laser treatment out to the ora serrata
Delivering laser treatment through small pupils or to eyes with semi-opaque
focal lenses
Contraindications for use:
Treatment sites close to the macula, within the arcades or where precise
positioning of
t
he Laser is not possible, should not be attempted
Opaque cornea or lens, or blood in the vitreous humor that interferes with
the Laser delivery to the tissue requiring treatment by scattering the beam
Do not treat albino patients that have no pigmentation
6.1.3 Endoprobe devices
The
Endoprobes
are
typically
used
during
Vitrectomy
to
perform
endophotocoagulation procedures such as sealing retinal holes during a retinal
detachment procedure or to perform panretinal photocoagulation (PRP) in the
treatment of diabetic retinopathy
The Endoprobe is a blunt intraocular needle fitted to a handle and connected to the
Laser unit by an optical fiber. The Red aiming beam is transmitted through the fiber
and allows clear identification of the position and size of the Laser spot.
The Endoprobes are used in a sterile environment and the doctor will observe the eye
through an Operating Microscope. A doctor safety filter must be fitted to the
operating microscope between the Binoculars and the Microscope. The correct
wavelength safety filter must be used to ensure for the safety of doctors’ eyes.
The Endoprobes are sterilized and single use devices. Their performance can degrade
which possible cause the delivered power decreased due to the transmission losses.
A spare Endoprobe should be kept available for any situations where the Endoprobe
is not performing satisfactorily.
Indications for use:
During vitreous surgery to produce a chorioretinal scar around retinal breaks
or retinal sites
To perform PRP in proliferative diabetic retinopathy
To perform intraoperative PRP on a scleral buckle
To perform intraoperative PRP around focal neovascularization
