Abstract Details

Purpose:

To review the results of the recently introduced Moorfields Safer Surgery Technique for Trabeculectomy Surgery in Malta. We compared the outcomes with those of the UK National Survey of Trabeculectomy -NST (2001) and the South East Scotland Trabeculectomy Survey -SESTS (2007)

Setting:

This review was done over a period of 18months, from the Maltese National Teaching Hospital, which services a population of just over 400,000 people.

Methods:

Files of all patients undergoing primary trabeculectomy with a minimum of 12 months follow up data available were identified from the hospital database and examined. Main outcome measure of success was defined as a 30% drop in final post-op IOP at 1 year. Secondary outcome measure of success was final IOP less than 21mmHg. Unqualified success was defined as satisfactory IOP without the use of IOP-lowering drops. Qualified success was defined as satisfactory IOP with concurrent use of IOP-lowering drops. Failure was defined as unsatisfactory IOP whereby further treatment such as diode laser or tube surgery was required.

Results:

43 eyes of 39 patients (mean age = 66.2 yrs ± 11.7) were analysed. All were Caucasian. 67.5% of patients had POAG, 10% had Primary Angle Closure Glaucoma, with the remainder comprising other glaucomas. The mean pre-operative IOP was 27.0mmHg ± 4.6 (26.4 NST). Mean post-op IOP was 15.3mmHg± 2.7. Unqualified success for main outcome measure was achieved in 64.1% of patients (NST: 66.1%, SESTS: 64.5%), qualified success in 82.1% (NST: 71.0%, SESTS: 65.5%). Unqualified success for secondary outcome measure was achieved in 72.7% (NST: 84%, SESTS: 91.1%) and 94.8% qualified (NST: 92%, SESTS: 93.8%). There was 6.8% failure rate.

Conclusions:

The Moorfields Safe Surgery Technique Trabeculectomy was only introduced to Malta in 2014. This is a retrospective review of all trabeculectomies performed by one surgeon (FC), using this method; having a minimum 12 months’ follow up data. The results compare favourably with those of the National UK Survey of 2001 and the South East Scotland Trabeculectomy Survey. Continued monitoring of outcome data will be of use to see how patients progress longer term.
