Outcomes of ab interno trabeculectomy with the trabectome by degree of angle opening.

ABSTRACT: To analyse ab interno trabeculectomy (AIT) with the trabectome and combined phacoemulsification with AIT (phaco-AIT) by Shaffer angle grade (SG).Prospective study of AIT and phaco-AIT with narrow angles of SG?2 versus open angles ?3. Outcomes included intraocular pressure (IOP), medications, complications, secondary surgery and success (IOP <21?mm?Hg and >20% reduction without further surgery). Exclusion criteria were missing preoperative data and <1?year follow-up.Of 671 included cases, at 1?year AIT SG?2 (n=43) had an IOP reduction of 42% from 27.3±7.4 to 15.7±3.0?mm?Hg (p<0.01) versus AIT SG?3 (n=271) with an IOP reduction of 37% from 26.1±7.8 to 16.4±3.9?mm?Hg (p<0.01). In phaco-AIT with SG?2 (n=48), IOP was reduced 24% from 20.7±7.0 to 15.7±3.6?mm?Hg (p<0.01) versus phaco-AIT with SG?3 (n=309) with an IOP reduction of 25% from 22.6±6.4 to 17.0±3.4?mm?Hg (p<0.01). There was no difference between SG?2 and SG?3 in reduction of IOP or medications, complications, secondary surgery and success rates (p>0.05).SG?2 is not associated with worse outcomes in AIT or phaco-AIT.
