Treatment Guidelines

Green 532nm

The 532nm green wavelength, with its mini‐ mal absorption by xanthophyll and strong absorption in melanin and haemoglobin, has for many years been considered the “gold standard” for treatment of the reti‐ na. Green laser light is primarily

absorbed by the retinal pigment melanin, and is therefore well suited for a variety of treatment applications in the retinal pigment epithelium (RPE) region. This pri‐ marily applies to pan‐retinal photocoagula‐ tion (PRP) therapy.

There are however some clinical limitations when using the 532nm green wavelength to treat in the retina; as absorption occurs at the vitreous level in cases of vitreous haem‐ orrhage, resulting in possible tissue dam‐ age and a decrease in energy available to produce the desired lesion.

Furthermore, if a layer of blood is present in the inner layer of the retina, then an increased energy uptake is produced in the inner retina, preventing treatment of deeper structures, such as a sub retinal neovascular membrane.

As a result, the use of complementing wavelengths to perform retinal
treatment such as 577nm yellow, 670nm red or 810nm infrared is often essential and warrants further investigation.

Treatment and Clinical Parameters for Green Laser


Contact Lenses for Slit Lamp Procedures


This technique is always used in the surgical environment as a final stage of Vitrectomy. Endophotocagulation is used for its retinopexy when treating detachments, and for applying pan-retinal photocoagulation (PRP) in the eye of a patient with diabetic retinopathy, usually in the severe proliferate stages.

Endophotocoagulation of retinal detachments:

In the retinal detachment surgery, endophotocoagulation is used to place a series of burns along the outside edge of a tear or hole after the retina has been returned to its normal position. This will prevent the migration of fluid under the edge of the tear or through the hole to lift the retina off again.

Endophotocoagulation of diabetic retinopathy:

In the final stages of a Vitrectomy, usually to remove the consequence of hemorrhage, a PRP is performed as if it were being done using the slit lamp. The treatment may include up to 300 applications, but is often less, if the patient has had previous outpatient PRP.

The ophthalmologists complete the PRP during the surgery, because many of these cases will have some additional haemorrhage. It is more practical to treat with the laser in while there is little or no haemorrhage present.

Tips for using the Endoprobe:

  • A 4x increase in power density is obtained for each millimetre the probe tip is moved closer to the retina.
  • It may be better to use longer working distances with higher powers. This allows the doctor to adjust the burn endpoint by moving the probe closer or further back from the retina.
  • When the doctor is applying laser in air, lower power is required.
  • When it is difficult to achieve a burn, very often there is fluid under the retina. Often after draining again good burns are obtained.
  • It is best to have grey endpoints; they will become lighter after a few minutes. This avoids over treatment.
