Clinical implication of recent randomized control trial in primary angle-closure disease management

Indian Journal of Ophthalmology, 2022
Blindness due to primary angle-closure glaucoma (PACG) can be reduced significantly if the ongoing angle-closure process is arrested at an early stage.

Laser iridotomy in dark irides [PDF]

British Journal of Ophthalmology, 2007
Laser iridotomy is the established treatment for angle-closure glaucoma. Nd:YAG (neodymium: yttrium-aluminium-garnet) laser iridotomy is challenging in the heavily pigmented irides of African and Asian patients,To present a modified laser iridotomy technique for use in dark irides.The argon laser was applied in two stages: firstly, low-power argon was ...

Laser Iridotomy [PDF]

BMJ, 1970
A ruby laser has been used to produce a permeable lesion in the iris to establish a communication between the anterior and posterior chambers. In a preliminary study in nine patients the technique gave satisfactory results in the prophylactic treatment of four cases of incipient closed-angle glaucoma and of two cases of iris bombé following uveitis.

Argon laser iridotomy. [PDF]

British Journal of Ophthalmology, 1985
Argon laser iridotomy was successfully performed on 47 out of 52 eyes of 35 patients by the continuous wave argon laser. The technique of argon laser iridotomy is described in detail. A number of complications were observed. The reasons for these are discussed, and measures for the avoidance of complications are suggested.

The effectiveness of early lens extraction with intraocular lens implantation for the treatment of primary angle-closure glaucoma (EAGLE): study protocol for a randomized controlled trial [PDF]

, 2011
Glaucoma is the leading cause of irreversible blindness. Although primary open-angle glaucoma is more common, primary angle-closure glaucoma (PACG) is more likely to result in irreversible blindness.

Insufficiency of YAG Laser Iridotomy to Prevent Pupillary Block Glaucoma in a Microspherophakic Patient with Weill-Marchesani Syndrome

İstanbul Medical Journal, 2018
Microspherophakia is a developmental disorder of the lens characterized by a small and spherical lens. Defective development of the lens fibers during embryogenesis was thought to be responsible for the abnormal size and shape of the lens.

Analysis of hybrid Nd:Yag laser-MAG arc welding processes. [PDF]

, 2011
In the hybrid laser-arc welding process, a laser beam and an electric arc are coupled in order to combine the advantages of both processes: high welding speed, low thermal load and high depth penetration thanks to the laser; less demanding on joint ...
