Outcome measures were: Surgical Success with 3 criteria - (i) criterion 1 = intraocular pressure (IOP) ≤ 21 mmHg or reduced by ≥ 20% of pre-operative IOP or IOP ≥ 6 mmHg on 2 consecutive time points after 3 months; (ii) criterion 2 = IOP ≤ 18 mmHg or reduced by ≥ 30% of pre-operative IOP or IOP ≥ 6 mmHg on 2 consecutive time points after 3 months and (iii) criterion 3 = IOP ≤ 15 mmHg or reduced by ≥ 40% of pre-operative IOP or IOP ≥ 6 mmHg on 2 consecutive time points after 3 months; IOP Reduction; Use of Anti-glaucoma Medication; Complications; Visual Acuity and Postoperative Interventions.Results: Median follow-up was 40 months (range 24– 77 months). At the final follow-up visit, the mean postoperative IOP was 11.5 ± 4.7 mmHg (p< 0.0001). Mean number of anti-glaucoma medications decreased from 2.45 ± 1.21 to 0.54 ± 0.95 (p< 0.0001). Surgical success in terms of IOP reduction was 50%; 43.2%; 36.4% for the 3 criteria respectively (complete success) and 70.5%; 56.8%; 47.7% for the 3 criteria respectively (qualified success). The complications noted were shallow/flat anterior chamber in 2 (4.54%), hyphema & bleb leak in 3 (6.81%), aqueous misdirection in 1 (2.27%), hypotonic maculopathy in 2 (4.45%) and hypotony requiring intervention in 6 (13.63%) eyes.Conclusion: Combined mDST was found to be an effective surgical procedure in reducing IOP. It was associated with complications commonly encountered in glaucoma filtering surgery. The use of intra-scleral space maintainer may help lower the risk of flat or shallow anterior chamber during the early postoperative period.Keywords: outcome and complications, combined modified deep sclerectomy and trabeculectomySangtam TRoy SMermoud ADove Medical Pressarticleoutcome and complicationscombined modified deep sclerectomy and trabeculectomyOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 795-803 (2020)
