The theoretic principles behind the laser were developed as early as 1917 when Einstein laid the groundwork for stimulated emission in his treatise “On the Quantum Theory of Radiation.” In 1949, Meyer-Schwickerath created chorioretinal burns around retinal holes using the sun as the light source.

Endoscopy, 1987
Endoscopic laser treatment has been tried for hemostasis, relief of stenosis and reduction of tumor volume in advanced upper gastrointestinal cancer. This form of treatment was found to be effective for each purpose, but success was usually only temporary.

Periodontology 2000, 2014
AbstractAbout 50 years ago, lasers started to be used in periodontal treatment following evidence that wounds produced in animals healed more quickly after being irradiated with low‐intensity lasers. Increased production of growth factors, stimulated mainly by red and infrared lasers, may participate in this process by influencing the behavior of ...

Lasers in Photodynamic Therapy
Nursing Clinics of North America, 1990Photodynamic therapy has been shown to provide a reasonable alternative to other treatment modalities for patients with certain cancers, and in some cases may be the preferred treatment. Currently, photodynamic therapy is under FDA-approved clinical investigational trials in the treatment of tumors of the skin, bronchus, esophagus, bladder, head and ...

Complications and Pitfalls of Laser Therapy
Endoscopy, 1986228 patients have been studied in retrospect, in an attempt to delineate the limits and pitfalls of laser treatment of benign (n = 104) and malignant (n = 124) tumors. Benign colorectal adenomas (n = 78) were divided into 3 groups according to the size of the lesion.

Laser therapy of childhood haemangiomas
British Journal of Dermatology, 1995A total of 37 haemangiomas were treated in 28 patients by means of the flashlamp-pumped pulsed dye laser (FPDL). Twenty-nine haemangiomas were classified as superficial, and eight as mixed type. With FPDL treatment, excellent or good results were obtained in nearly 60% of superficial haemangiomas and 40% of mixed haemangiomas. In three of four patients

Laser therapy of gastrointestinal tumors
World Journal of Surgery, 1992AbstractSurgical resection remains the therapy of choice for the treatment of potentially curable gastrointestinal tract (GI) malignancies. Many of these tumors are incurable at the time of diagnosis and therapy should be directed towards palliation with the intent of minimizing pain, bleeding, obstruction, and potential morbidity.

Laser Therapy for Retinopathy of Prematurity
Journal of Pediatric Ophthalmology & Strabismus, 1993ABSTRACT Nine patients were treated with indirect ophthalmoscope argon laser photocoagulation for threshold retinopathy of prematurity (ROP). A total of 16 eyes were treated at an average postconceptional age of 36.31 weeks. All eyes demonstrated regression of threshold ROP. Follow up was between 1 and 14 months postoperatively.
