Clinical studies comparing trabeculectomy augmented with Ologen implant (OLO) versus trabeculectomy plus mitomycin-C (MMC) show contradictory results. To obtain long-term data, we report an extended 5-year follow-up trial evaluating the safety and efficacy of OLO as adjuvant compared to low-dosage MMC in trabeculectomy. Forty glaucoma patients (40 eyes) assigned to trabeculectomy with MMC or Ologen. Primary outcome: target IOP at ≤21, ≤17 and ≤15 mmHg; complete and qualified success endpoint rates. Secondary outcomes: visual acuity (VA), mean deviation (MD), bleb evaluation, according to Moorfields Bleb Grading System (MBGS); spectral domain OCT (SD-OCT) bleb examination; number of glaucoma medications; frequency of postoperative complications. The mean preoperative IOP was 26.7(±5.2) in MMC and 27.3(±6.0) in OLO eyes. Mean 60-month percentage reduction in IOP was significant in both groups [40.9 (±14.2) and 42.1(±13.3) P = 0.01], with an endpoint value of 15.2 (±3.2) and 15.8 (±2.3) mmHg in MMC and OLO, respectively. Complete success rates at ≤ 21 mmHg target IOP were 65 % and 70 %, at ≤17 mm Hg 60 % and 55 %, and at the ≤15 mm Hg target IOP 35 % and 45 % in MMC and OLO, respectively. The Kaplan–Meier curves did not differ both for complete and qualified success at any target IOP, with no significant endpoint intergroup difference at ≤ 15 mm Hg (log-rank P = 0.595).The intergroup MBGS scores differed due to reduced central and peripheral vascularity in MMC group (P = 0.027; P = 0.041). SD-OCT analysis denied differences in bleb height between MMC vs OLO (140.5 ± 20.3 μ vs 129.2 ± 19.3 μ respectively; P =0.079). Mean antiglaucoma medications were significantly reduced (P < 0.0005) from 2.5 (±0.3) to 1.2 (±0.4) in MMC and from 2.6 (±0.2) to 1.4 (±0.3) in OLO group, with no intergroup differences (P = 0.08). Six (30 %) cystic thin avascular blebs without oozing were recorded in the MMC group and 2 (10 %) in the OLO group, without intergroup difference (P = 0.235). Our extended follow-up results confirm that Ologen implant yields efficacy and long-term success rates quite similar to MMC, with at least equivalent safety.
Open globe eye injuries can have profound social and economic consequences. Here, we describe two cases of war and outdoor activity open globe eye injury where, despite a low OTS score, current microsurgical technology allowed for a favorable outcome.A 33-year-old Libyan soldier had been treated for an open-globe grenade blast trauma to his left eye, which showed light perception and OTS score 2. He had undergone a lensectomy and PPV with silicone oil tamponade. Surgical treatment included scleral buckling, cornea trephination, temporary Eckardt keratoprosthesis, PPV revision, intraocular lens (IOL) implantation, and corneal grafting. Six months later, his VA was improved to 20/70. CASE REPORT 2: A 35-year-old man presented with a corneal laceration in his left eye from a meat skewer, with marked hypotony and LP. After primary corneal wound closure, B-scan ultrasonography revealed massive vitreous hemorrhage (OTS score 2). The patient underwent open cataract extraction with IOL implantation, 23 gauge PPV, laser photocoagulation of the retinochoroidal laceration, and a gas tamponade. After three weeks, the patient underwent a 2nd 23G PPV due to a fibrinous reaction. Six month later, the patients exhibited 20/25 VA.These cases confirm that even for patients with a low OTS and poor visual prognosis, an up-to-date surgery protocol may achieve visual results adequate for leading an autonomous daily life.
