Abstract

A one-piece silicone filtration implant for glaucoma surgery was evaluated in 18 normotensive rabbits. During the follow-up period of 60 days the function of the implant and the effect of the implant on intraocular pressure (IOP) and local reaction in operated eyes were examined.

Mean IOP in operated eyes during the whole follow-up period stayed in a level that was statistically significantly (p<0.001) lower than the preoperative starting value. Despite of a slight inflammatory reaction in the immediate postoperative period the implants were well tolerated. No marked foreign body reaction were noted around the implants in histological sections. In 3 eyes the implants had to be removed due to complications caused by surgical technique.

Sammanfattning

Ett filtrationsimplantat av silikon i ett stycke för glaukomkirurgi evaluerades i 18 kaniner med normalt ögontryck.

Implantatets funktion, inverkan på ögontryck och lokal reaktion i opererade ögon uppföljdes under 60 dagar.

Medelvärdet av ögontrycket stannade under hela uppföljningstiden på en nivå, som var statistiskt signifikant lägre än det preoperativa värdet. Med undantag av en lindrig lokal reaktion just efter operationen, tolererades Implantaten väl. Ingen nämnvärd främmandekropp reaktion förekom i histologiska preparat. I 3 ögon måste implantaten avlägsnas på grund av komplikationer orsakade av kirurgiska tekniken.
