Abstract
BACKGROUND Aniridia is a rare eye disorder with a high incidence of glaucoma, and surgical intervention is often needed to control the intraocular pressure (IOP). Here, we reported a case of illuminated microcatheter-assisted circumferential trabeculotomy (MAT) performed on an aniridic glaucoma patient following a previous failed angle surgery. The surgical procedures for aniridic glaucoma were also reviewed. CASE PRESENTATION A 21-year-old man, diagnosed with aniridic glaucoma, came to our hospital consulting for the poor control of left eye's IOP despite receiving goniotomy surgery 3 years ago. The IOP was 26 mmHg with maximum topical antiglaucoma eyedrops. The central cornea was opaque and the majority of iris was absent. The gonioscopy and ultrasound biomicroscopy (UBM) demonstrated that 360° anterior chamber angle was closed. The whole exome sequencing of peripheral blood confirmed a 13.39 Mb copy number loss at chromosome 11p15.1p13, containing PAX6 and WT1 gene. The 360° MAT surgery was performed on his left eye. At 1-year follow-up, the IOP was 19mmHg with 2 kinds of topical antiglaucoma medications, and the postoperative UBM demonstrated the successful incision of the anterior chamber angle. CONCLUSIONS The case presented here exhibited a case of aniridic glaucoma treated by MAT surgery. The MAT surgery may be an effective option for IOP control in aniridic glaucoma patients following a previous failed angle surgery.

Abstract
Aniridia is a congenital bilateral ocular disorder with dominant autosomal inheritance. More than 50% of patients will develop aniridic glaucoma (AG) during their lives. Open angle glaucoma is more common in aniridia, but a closed angle mechanism has been described in relation with anterior rotation of the rudimentary iris, occluding trabecular meshwork. Diagnosis and follow-up of AG is difficult in relation with the presence of keratopathy, nystagmus and foveal hypoplasia. Central corneal thickness usually measures more than 600 microns, which prevents achieving a reliable value of intraocular pressure. Medical treatment of AG is no different from the rest of glaucoma. It is recommended to use preservative free formulations, and combined therapy is often required. Surgical treatment is needed in many cases. There is no consensus on the first line surgery for AG, but in open angle AG, angle surgery is usually first choice, and glaucoma drainage devices are the next preferred surgical technique. In closed angle AG glaucoma drainage devices are usually the first choice, with trabeculectomy as the second preferred surgical technique.

Abstract
PURPOSE To study the long-term intraocular pressure (IOP) and visual outcomes in treated aniridic glaucoma. METHODS A retrospective chart review of patients with aniridia and glaucoma, with ≥ 2-year follow-up, was performed. Eyes in early glaucomatous stages were medically managed, while moderate-severe stage eyes underwent a trabeculectomy with mitomycin-c (MMC). Success was termed 'complete' when average final IOP was ≤ 18 mmHg without usage of glaucoma medications, and 'qualified' when with/without topical glaucoma therapy. A significant change in vision was defined as > 2-line change on Snellen vision chart or > 0.2 change in logMAR units in in either direction (better or worse). RESULTS Thirty-five eyes of 20 patients were included. The mean duration of follow-up was 7.29 ± 5.75 years. Associated ocular anomalies were present in 19 eyes (54.29%). Twelve eyes (34.28%) were maintained on medical management, while 23 eyes (65.71%) had undergone a trabeculectomy with MMC. The mean baseline IOP was 31.46 ± 6.34 mmHg, and mean IOP on last follow-up was 13.25 ± 5.82 mmHg, p < 0.001. Seventy-five percent of the medically managed eyes achieved an IOP ≤ 18 mmHg. 52.17% and 95.65% of the surgically treated eyes achieved 'complete' and 'qualified' success respectively. The median best corrected visual acuity (BCVA) at baseline was 1.48(0.6-2) logMAR units and on final follow-up was 1.3 (0.48-5) logMAR units, p = 0.21. Fifty percent of the eyes remained stable, 35.71% showed an improvement and 14.29% a deterioration of > 0.2 logMAR units. Patients with a longer follow-up (> 10 years) and those who had undergone a trabeculectomy with MMC were more likely to show good IOP control (p = 0.003; p = 0.004 respectively). CONCLUSION Aniridic glaucoma can be managed efficiently by medications in early glaucomatous neuropathy, and with trabeculectomy augmented with mitomycin-C and releasable sutures for more advanced glaucomas, offering favourable long-term IOP control, visual stability and safety.

Abstract
Purpose To investigate the clinical features of Korean patients with congenital aniridia. Methods This retrospective study focused on 60 eyes from 31 patients who were diagnosed with congenital aniridia at Kangnam St. Mary's Hospital from 1996 to 2007. Patient age, gender, visual acuity (VA), family history, and previous ocular history were recorded. The presence of keratopathy, glaucoma, cataract, foveal hypoplasia, and other ocular or systemic anomalies were evaluated for each patient. Results The proportion of sporadic cases was 29.0%. Cataract (82.5%), glaucoma (51.6%), keratopathy (71.6%), and foveal hypoplasia (81.8%) commonly accompanied aniridia. Thirty-four (60.7%) eyes had VAs less than 20/200 and 20 eyes (35.7%) had VAs between 20/200 and 20/60. In patients without a past history of ocular surgery, the mean central corneal thickness was 643.05 ± 37.67 µm and the mean endothelial cell count was 3,349.44 ± 408.17 cells/mm2. Ocular surface surgeries were performed in 6 eyes. The clarity of the transplanted corneal graft vanished in 5 eyes with the progression of peripheral neovascularization and subepithelial fibrosis. The mean age of cataract surgery in 8 eyes was 29.8 ± 5.9 years. Postoperative worsening of corneal clouding and glaucomatous damage were observed in 4 eyes. Two infants had bilateral congenital glaucoma. Two children with sporadic aniridia were identified to have Wilm's tumors. Conclusions Congenital aniridia is a progressive congenital disorder that is commonly accompanied by complications that can lead to impaired vision. Regular, careful examinations for these accompanying complications should be performed in all patients with congenital aniridia.
