to evaluate intra ocular pressure (IOP) levels, visual acuity, rate of complications and visual field stability, in a short, medium and long term follow-up of deep sclerectomy compared to combined phacoemulsification -IOL implantation-deep sclerectomy
a monocentric, retrospective, comparative study including 140 patients with medically uncontrolled primary open angle glaucoma (POAG). They were subdivided in 2 groups, one of which underwent deep sclerectomy (group 1), and the second, combined phacoemulsification-IOL implantation-non penetrating deep sclerectomy (group 2). The postoperative examinations were performed between day 1 and month 24. The parameters evaluated were: IOP levels, visual acuity, optic nerve head evaluation, survival of the filtration blebs, mean deviation and pattern standard deviation in the visual field examination. Early and long-term complications and postoperative glaucoma medication following both procedures were evaluated as well.
the mean preoperative IOP was 27,8 mmHg in group 1 and 24,9 mmHg in group 2. At the end of the follow-up period, the mean IOP was 17,3 mmHg in group 1 and 16,4 mmHg in group 2 with the postoperative IOP significantly lower (p<0,005) than the preoperative IOP in the two groups.There was no significant difference between the mean reduction of IOP at the end of the follow-up periode in the two groups of patients( p>0,005). The mean preoperative visual acuity in group 1 was 0,18 LogMAR and 0,3 LogMAR in group 2. At the end of the follow-up period the visual acuity in group 1 was 0,3 LogMAR and 0,1 LogMAR in group 2 with a significant difference of the visual outcome between two groups. We didn't find any significant difference in the rate of complications and the postoperative glaucoma medication in the two groups. The difference in the survival of the filtration blebs in two groups was not significant but we noted an increased number of needlings and 5FU injections in group 2.
