“…Others reported 5-FU injection rates between 6 and 50%. 8,13,14,16 The number of YAG-goniopunctures performed in our study is lower compared to published data, 16,19,24 which might be owing to the exact dissection with the laser, resulting in a very thin TDM.…”

“…The rate of choroidal detachment, hyphema, and shallowing of the anterior chamber is comparable to the data in the literature (range: 0-33%). 11,13,14,17,23 Average preoperative BCVA was low in our study group, as two patients had poor visual fields, two patients developed cataracts and pre-existing cataracts progressed in another four patients. Other studies with a long-term follow-up have shown similar cataract progression rates compared to our study.…”

“…Here, we provide long-term results with follow-up of more than 4 years. In 2002, Verges et al 13 published excellent results after Erbium YAG-laserassisted DS, with a complete success rate of 84.78% after 15 months (defined as an IOPp18 mmHg without medication), that was better than the results we could achieve. Pallikaris et al 14 reported a complete success rate of 50% after 12 months and 37.5% after 24 months (defined as an IOPp21 mmHg without medication) with the same technique.…”

“…All 14 patients developed a filtering bleb, which is in line with other studies. 9,11,13,14 Eleven of them required 5-FU injections due to signs of bleb fibrosis. This indicates a role of subconjunctival aqueous drainage in IOP reduction after DS or laserassisted DS.…”

“…Previous studies showed that the dissection of the deep corneoscleral lamella with the Erbium YAG-laser might greatly simplify this delicate step, resulting only in a small thermal damage zone. [12][13][14] Purpose of this study was to evaluate the long-term results of Erbium YAG-laser-assisted DS after a follow-up period of up to 56 months.…”

Purpose To evaluate the long-term results of Erbium YAG-laser-assisted deep sclerectomy (DS). In this procedure, the delicate dissection of a deep corneoscleral lamella is greatly simplified by using the Erbium YAG-laser. Methods Data of 14 consecutive patients (10 male, four female, age 67.7710.4 years), who underwent surgery from 1999 to 2000 were analysed retrospectively. The procedure was begun as a standard DS. The deep corneoscleral lamella was dissected with a pulsed Erbium YAG-laser (energy: 40-100 mJ, frequency: 5-10 Hz). Schlemm's canal was unroofed and the lamella thinned until aqueous percolated continuously through the membrane. Results The mean follow-up time was 50.476.8 months. The mean preoperative intraocular pressure (IOP) was 37.7710.5 mmHg. The mean postoperative IOP was 16.173.9 mmHg at 1 month, 15.174.3 mmHg at 3 months, 16.474.5 mmHg at 12 months, and 17.678.7 mmHg at 50.5 months. The complete success rates (IOPp21 mmHg þ IOP reduction X20% without glaucoma medication) were 83.3% at 3 months and 50% at 12 and 50.5 months. Rates for qualified success (IOPp21 mmHg þ IOP reduction X20% with glaucoma medication) were 91.7% at 3 months, 92.9% at 12 months, and 78.6% at 50.5 months. The number of glaucoma medications was reduced from 3.0770.92 preoperatively to 1.1471.41 at 50.5 months. A single case of anterior-chamber penetration, requiring iridectomy, was the only intraoperative complication. Conclusions Erbium YAG-laser-assisted DS has the advantage of a greatly simplified dissection, while offering a successful long-term IOP control comparable to conventional DS.
