Laser Iridectomy Therapy of Glaucoma
Archives of Ophthalmology, 1973Seventeen iridectomy attempts were performed on 16 eyes using ruby, neodymium, and argon lasers. None of these was found suitable for iridectomy formation in blue eyes. Ruby wavelength was found to be the wavelength of choice in brown eyes, yielding a patent iridectomy in six out of six attempts. Attempts with neodymium and argon were disappointing. No

Corneal Decompensation After Argon Laser Iridectomy
Archives of Ophthalmology, 1989To the Editor. —We have had the pleasure of reading the article by Schwartz et al 1 in the November 1988 issue of theArchivesregarding corneal decompensation after argon laser iridectomy. Although all of us have seen corneas occasionally decompensate after an attack of angle closure glaucoma or after surgical procedures, our experience suggests less ...

Corneal Decompensation After Argon Laser Iridectomy
Archives of Ophthalmology, 1988Five eyes of three patients developed generalized corneal decompensation after undergoing argon laser iridectomy for angle closure glaucoma. Factors possibly associated with corneal decompensation include episodes of angle closure glaucoma with pressure elevations and inflammation, corneal guttate, diabetes, and the need for multiple treatments ...

Physics in Medicine & Biology, 1977
The laser energy required to achieve an iridectomy in the human eye is calculated as a function of laser beam radius and pulse duration. Two widely different models of the stromal pigment distribution are used in order to embrace the range of coloured irides encountered in practice.

Nd:YAG Laser Iridectomies: 100 Consecutive Cases
Ophthalmic Surgery, Lasers and Imaging Retina, 1988ABSTRACT We reviewed the patient charts of our first 100 consecutive Nd:YAG laser iridectomies. Our success rate (99%) is the same as that reported by others. Iris bleeding was not problematic. We did find that relative pupillary block may still be present with a patent but very small Nd:YAG iridectomy; that transillumination is not an ...

An “Exploding Cataract” Following Nd:YAG Laser Iridectomy
Ophthalmic Surgery, Lasers and Imaging Retina, 2003A case of an “exploding” cataract (an iatrogenic posterior capsular rupture) following Nd:YAG laser iridectomy is described. Rapid cataract development was observed in the right eye of a 76-year-old woman following an iridectomy. B-scan ultrasonography documented cortical debris in the vitreous cavity.

Thermoelastic analysis of laser iridectomies
Journal of Biomedical Engineering, 1989We have attempted to derive the stress-strain-temperature relationships of the iris stroma subject to a restrictive thermal burn from a laser. The corresponding displacement equation embodies the mechanical impulses due to this thermal insult. This thermoelastic analysis of laser iridectomy attempts to describe the mechanism involved in the surgical ...

Laser Iridotomy vs Surgical Iridectomy
Archives of Ophthalmology, 1985The number of laser iridotomies in 1982 was more than four times the annual rate of surgical iridectomies performed before the laser was in common use at the Bascom Palmer Eye Institute, Miami. No single reason accounts for the increase. Only a minority of the increase is due to a 32% increase in our outpatient volume, a backlog of individuals with ...

Central Anterior Chamber Depth After Laser Iridectomy
American Journal of Ophthalmology, 1980We found the true anterior chamber depth to be unaffected by successful laser iridectomy in ten eyes treated by this modality for chronic angle-closure glaucoma. The apparent general deepening seemed to be the result of peripheral chamber deepening combined with the common use of strong cycloplegic agents, reversing the shallowing effect of ...

Histopathology of Neodymium:YAG Laser Iridectomy in Humans
Ophthalmology, 1985Fifteen peripheral iridectomy specimens were obtained, with informed consent, from patients with primary narrow angle glaucoma, after previous neodymium:YAG (Nd:YAG) laser iridectomy. The iridectomies were performed three hours to ten weeks after laser application.
