Infrared 810nm Wavelength
The infrared 810nm (commonly referred to as the Diode Laser) is a wavelength of unique characteristics, with niche clinical applications, and a great alternative to 532green and 670red wavelengths espe‐ cially when a deep penetration is re‐ quired. However due to the invisible properties, the 810nm is a wavelength that requires more understanding and expertise than the visible wavelengths, hence the reason why it has not gained the mass popularity.
The lesions produced by 810nm lasers are not immediately noticeable as the same lesions produced by green lasers. Com‐ monly, the lesions take a few days to ap‐ pear (depending on the patient), and once they become apparent, they may appear indistinguishable, both in look and clinical feature to the lesions produced by green lasers. During the treatment, the physician can monitor this effect and adjust the power settings by referring to the colour of the retinal lesion, which will usually appear slightly grey.
The 810nm wavelength is less absorbed by melanin than that of the green wave‐ lengths (532nm & 514nm); thus patients with low pigmentation (fair skin) may require higher power settings to photo‐ coagulate the tissue. However, for pa‐ tients with high pigmentation, the differ‐ ence between 810nm and green (532nm & 514nm) wavelengths is negligible.
Because of the invisible 810nm spectrum the diode laser has the advantages of penetrating through sclera, and excessive haemorrhage hance the wavelength has established itself as a standard in niche laser applications such as Retinopathy of Prematurity (ROP), Transscleral Cylcopho‐ tocoagulation or Transpupillary Thermo‐ Therapy, known more commonly as TTT (in treatment of ocular tumours) and CNV and in treatment some AMD cases.
TTT, relies on heat generation from en‐ dogenous pigment (hyperthermia princi‐ ple) for the treatment of Ocular Tumours and Choroidal Neovascularization (CNV).
Transscleral Cylcophotocoagulation (also known as TSCPC) of the ciliary processes. The ciliary body of the eye, which creates aqueous fluid, is treated with a laser to decrease production of aqueous. TSCPC has been demonstrated to be a safe and highly effective method for low‐ ering intraocular pressure (IOP) in pa‐ tients with severe uncontrolled glaucoma where previous medications and treat‐ ments have not shown to be effective.
The infrared 810nm wavelength is the versatile alternative in deep penetration.
- Highly absorbed by the melanin present in the Retinal Pigment Epithelium
- Well absorbed by haemoglobin
- Good transmission through haemorrhages and vitreous opacities
- Good penetration through sclera
Main Clinical Applications
- Diabetic Retinopathy
- Central serous chorio-retinaopathy
- Diabetic Macular Edema
- Central/Branch Retinal Vein Occlusion
- Retinopathy of Prematurity (ROP)
- Retinal Tears, Holes, and Detachments
- Laser Trabeculoplasty
- Laser Iridotomy
- Peripheral Iridectomy
- Sub-Threshold Photocoagulation Laser Trabeculoplasty (spLT)
- Transpupillary Thermo-Therapy (TTT)
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.
