6.1 Different types of LDUs Indication / Contraindication Use
There are three different types of delivery system such as, Slitlamp Delivery unit, LIO
and Endoprobes. They are explained in great detailed for their specific indication and
countraindication uses as follows.
6.1.1 Slitlamp Delivery Unit
The Slitlamp Delivery unit allows the treatment of many Retinal conditions and
Glaucoma while still being able to use all the standard diagnostic functions of the
Slitlamp to which it is fitted.
Indications for use:
 Proliferative and non-proliferative diabetic retinopathy
 Retinal tears and detachments
 Lattice degeneration
 Laser trabeculoplasty in glaucoma treatment
Contraindications for use:
 Opaque cornea or lens, corneal edema, or blood in the vitreous humor that
interferes with the treatment by scattering the beam
 Albino patients or eyes that have no pigmentation.
Additional Contraindications for use in trabeculoplasty:
 Aphakic eye with vitreous in the anterior chamber
 Neovascular glaucoma
 Glaucoma caused by congenital abnormalities of the angle
 Glaucoma secondary to active uveitis
 Less than 90° of open angle or extensive low-lying peripheral anterior
synechiae present around the circumference of the angle
6.1.2 Laser Indirect Ophthalmoscope (LIO)
The Laser Indirect Ophthalmoscope allows for the treatment of panretinal disorders
and adds the capability of transpupillary retinal photocoagulation to the diagnostic
indirect ophthalmoscope. Use of the LIO enables delivery of the laser to pathologies
in the far periphery of the retina and for treatment of supine patients.
Indications for use:
 Proliferative and nonproliferative diabetic retinopathy with pathology
outside the arcades
 Retinal tears
 Lattice degeneration
