Abstract
|
|
|
Argon laser photocoagulation of iris with different numbers of laser burn and laser iridotomy were performed in 64 rabbit eyes, using a modified contact lens of Abraham, by means of two techniques according to the duration of laser burn. Short-burn techni-que was carried out with the duration of 0.02 seconds and the duration of long-burn technique was 0.2 seconds. Intraocular pressure(IOP) tended to increase 30 minutes after laser photocoagulation during the follow-up period of 2 hours and the increase was significant in the laser iridotomy group (mean numbers of laser burn: 138) irradiated by long-burn technique(p<0.05). Aqueous protein of anterior chamber aspirated 2 hours after laser photocoagulation showed to increase significantly in all groups treated with laser and tended to increase with the numbers of laser burn. Howel´r, there was no significant difference in the aqueous protein according to the techniques of laser photocoagulation short burn and long-burn techniques.
Short-bum technique of laser iridotomy was superior to long-bum technique which needs more laser energy delivered to the eye during laser photocoagulation and releases more aqueous protein of anterior chamber than short-bum technique.
