Ab-Interno Sclerostomy Using a Goniodiathermy Instrument
Ophthalmic Surgery, Lasers and Imaging Retina, 1994ABSTRACT We describe the use of a new instrument designed to create a simultaneous goniopuncture with diathermy using an ab-interno technique. The goniodiathermy ab-interno procedure was first performed on three eyes of three cynomolgus monkeys.

Laser Sclerostomy by Pulsed-Dye Laser and Goniolens
Archives of Ophthalmology, 1990We describe an ab-interno laser sclerostomy procedure using the method termed dye-enhanced ablation with a slit-lamp delivery system and special goniolens such that only the laser light beam penetrates the anterior chamber. The procedure uses a microsecond-pulsed-dye laser emitting at 666 nm and iontophoresis of methylene blue dye (absorption of 668 nm)

Mitomycin-C in Laser Sclerostomy: Benefit and Complications
Ophthalmic Surgery, Lasers and Imaging Retina, 1997* BACKGROUND AND OBJECTIVE: The authors studied the effect of topical mitomycin-C administration on the maintenance of filter function and intraocular pressure (IOP) following laser sclerostomy. * PATIENTS AND METHODS: Twenty-six patients with a presumed high risk of episcleral scarring were treated intraoperatively with topical mitomycinC (0.

THC:YAG Laser Sclerostomy: The Resident Experience
Ophthalmic Surgery, Lasers and Imaging Retina, 1992ABSTRACT Retrospective review of 14 consecutive THC: YAG laser sclerostomies done without the use of antimetabolites revealed a uniform closure of the filtering bleb within 6 months of follow up. Also, the sclerostomy site was closed by iris or fibrous tissue.

[Physical principles of sclerostomy].
Klinische Monatsblatter fur Augenheilkunde, 1993Various sclerostomy procedures, performed ab interno and ab externo have found increasing interest for some time. With few exceptions, invasive procedures are described, in which laser energy is transmitted by means of specially designed fibers and probes ab interno and ab externo to the perforation site.

Sclerostomy with an Erbium YAG Laser The Relationship with Pulse Energy
Japanese Journal of Ophthalmology, 2001Purpose: To investigate the optimal pulse energy to do sclerostomy with an erbium YAG laser.Materials and Methods: The experiments were performed in enucleated porcine eyes. We changed pulse energy and examined the effects on surrounding tissue.Results: With the increase of pulse energy, the effects of the laser extended to the area surrounding the ...

Ab Interno Sclerostomy With a High-Powered Argon Endolaser
American Journal of Ophthalmology, 1988We used a high-energy argon blue-green laser (15-W maximum power output) to create full-thickness sclerostomies from the region of the anterior chamber angle to the subconjunctival space in pigmented rabbits using an ab interno approach. One to four laser pulses delivered through a 300-micron noncontact fiberoptic probe produced patent sclerostomies in

Bipolar Cautery and Internal Thermal Sclerostomy in a Rabbit Model
Ophthalmic Surgery, Lasers and Imaging Retina, 1992ABSTRACT Internal thermal sclerostomy (ITS) was performed unilaterally in 35 adult New Zealand rabbits using a pinpoint bipolar cautery probe and radio-frequency power supply, with the nonoperated eyes serving as controls. Standard trabeculectomy using a limbal-based flap was also performed on 10 additional rabbits, and served as a second ...

Is Laser Sclerostomy Surgery Ready for 'Prime Time'?
Archives of Ophthalmology, 1995There aremany controversial areas within ophthalmology, and undoubtedly the field of glaucoma carries its lion's share. Consider filtration surgery as an area replete with debatable issues. The technique of conventional filtration surgery varies among surgeons, so comparing one series of patients with another becomes difficult.

THC:YAG Laser Sclerostomy with Mitomycin Subconjunctival Injection in Rabbits
Journal of Ocular Pharmacology and Therapeutics, 1992We performed sclerostomy using THC:YAG laser (thulium, holmium, chromium doped YAG crystal) and subconjunctival injection of mitomycin soon after the filtering process in rabbits to observe the lowering effect of intraocular pressure(IOP) and filtering bleb formation.
