Retinal Laser Procedures
Focal Laser
Focal treatment is used to seal specific leaking blood vessels in a small area of the retina, usually near the macula. The ophthalmologist identifies individual blood vessels for treatment and makes a limited number of laser burns to seal them off.
 
Panretinal Photocoagulation
A special laser is used to make tiny burns that seal the retina and stop vessels from growing and leaking. Hundreds of tiny spots of laser are placed in the retina to reduce the risk of vitreous hemorrhage and retinal detachment
Optical coherence tomography (OCT)
Optical coherence tomography (OCT) is an optical signal acquisition and processing method. It captures micrometer-resolution, three-dimensional images from within optical scattering media (e.g., biological tissue). Optical coherence tomography is an interferometric technique, typically employing near-infrared light. The use of relatively long wavelength light allows it to penetrate into the scattering medium. Confocal microscopy, another similar technique, typically penetrates less deeply into the objective.

Heidelberg Retina Tomography (HRT)
Glaucoma is a disease of the optic nerve causing progressive loss of nerve tissue and visual loss. Treatments are aimed at slowing this progressive visual loss. For many years the only way progression was monitored was subjective clinical examination by a physician. While physician examination is still crucial to glaucoma treatment, the HRT has given our physicians an objective testing measure to follow glaucoma progression. HRT is the only advanced imaging device to quantitatively measure the three vital structures, cup, rim, and retinal nerve fiber layer, needed to make a complete assessment of glaucoma. This is important because damage can be detected at one or more of these locations depending on individual patient anatomy and susceptibility.
 
Fluorescein Angiography
Fluorescein angiography, or fluorescent angiography, is a technique for examining the circulation of the retina using the dye tracing method. It involves injection of sodium fluorescein[1] into the systemic circulation, and then an angiogram is obtained by photographing the fluorescence emitted after illumination of the retina with blue light at a wavelength of 490 nanometers. The fluorescein dye also reappears 12-24 hours in the patient urine, causing a yellow-green appearance.
