Purpose. To evaluate the outcome of primary nonpenetrating deep sclerectomy (NPDS) in patients with steroid-induced glaucoma. Methods. This was a retrospective interventional clinical study that included 60 eyes of 60 steroid-induced glaucoma patients that had undergone NPDS. Patients were followed up for 4 years. Data from the records was retrieved as regards corrected distance visual acuity (CDVA), intraocular pressure (IOP), visual field mean defect (dB), and number of antiglaucoma medications needed if any. Complete success of the surgical outcome was considered an IOP ≤ 21 mmHg with no antiglaucoma medications. Qualified success was considered an IOP ≤ 21 mmHg using antiglaucoma medications. Results. The mean age was 21.2 ± 8.5 years (ranged from 12 to 35 years). At 48 months, mean IOP was 13.6 ± 2.8 mmHg (range 11–23 mmHg). This represented 60% reduction of mean IOP from preoperative levels. One case had YAG laser goniopuncture. Three cases required needling followed by ab interno revision. Using ANOVA test, there was a statistically significant difference between preoperative and postoperative mean IOP values (P=0.032). Twelve, 16, and 20 patients required topical antiglaucoma medications at 24, 26, and 48 months postoperative, respectively. Conclusion. Primary nonpenetrating deep sclerectomy is a safe and an effective method of treating eyes with steroid-induced glaucoma. No major complications were encountered. After 4 years of follow-up, complete success rate was 56.7% and qualified success rate was 70%.

Objective: The aim of this study is to compare the efficacy of the trabeculectomy in controlling intraocular pressure in patients with primary open-angle and pseudo-exfoliation glaucoma. Materials and Methods: The medical data of a sum of 69 eyes of which 36 (52,2%) with primary open angle glaucoma (POAG) and 33 (47,8%) with pseudo-exfoliation (PEG), who have medically uncontrolled glaucoma and had undergone primary trabeculectomy in Göztepe Education and Research Hospital were evaluated in this retrospective study. Postoperatively, data at the first day, at the first month, and at the last examination evaluated in the study. Success of the surgery is defined as measurement of intraocular pressure under 21 mmHg with (incomplete success) or without (complete success) additional medications following the end of the first year follow-up examinations. Results: POAG group consists of 36 patients of which 16 male, 20 female and PEG group consists of 33 patients of which 21 male and 12 female. The mean age was 67.2±9.1 (42-80) years in POAG group and 70.7±6.6 (55-80) years in PEG group. There was no statistically significant difference between POAG and PEG groups in visual acuity, mean intraocular pressure, c/d ratio and the number of antiglaucomatous medications preoperatively and postoperatively (p>0.05). There was a statistically significant difference in groups between post and preoperative values in visual acuity, mean intraocular pressure, c/d ratio and the number of antiglaucomatous medications (p<0.05) Success of the trabeculectomy was 41,7% (complete success), 41,7% (incomplete success) and remaining 16,6% was unsuccessful, in POAG group and success rate in PEG group was 51.5%, 27,3% and 21,2% respectively. There was no statistically significant difference between groups (p=0.738). Conclusion: Trabeculectomy is an effective surgery in lowering intraocular pressure in both of the study groups equally.

Objectives: Evaluate the efficacy of transscleral cyclophotocoagulation versus endoscopic cyclophotocoagulation to reduce intraocular pressure. Methods: A retrospective, non-randomized cohort study with 1 year of follow-up included 62 eyes of 62 refractory glaucoma patients who underwent transscleral cyclophotocoagulation or endoscopic cyclophotocoagulation. Results: Thirty-two patients were enrolled in transscleral cyclophotocoagulation group and 30 patients in endoscopic cyclophotocoagulation group, and the follow-up period was 1 year. The mean preoperative intraocular pressure was 35.6 ± 12.9 mm Hg in the transscleral cyclophotocoagulation group and 31.8 ± 8.8 mm Hg in the endoscopic cyclophotocoagulation group without significant difference ( p = 0.18). When we compare both groups, there was no difference at 1 month ( p = 0.46) and 3 months ( p = 0.21) after surgery. However, there was a statistically significant difference at month 6 ( p = 0.0055) and 1 year ( p = 0.0019), finding lower intraocular pressure in the transscleral cyclophotocoagulation group. Cumulative success for intraocular pressure <21 mm Hg was 93.8% in transscleral cyclophotocoagulation group and 83.3% in endoscopic cyclophotocoagulation group after 1 year ( p = 0.2). For intraocular pressure <18 mm Hg, the success rate was 78.1% in transscleral cyclophotocoagulation group and 63.3% in endoscopic cyclophotocoagulation group ( p = 0.06), and for intraocular pressure <16 mm Hg, the success rate was 62.5% in transscleral cyclophotocoagulation group and 43.3% in endoscopic cyclophotocoagulation group ( p = 0.02). Hypotony ( p = 0.01) and vision loss of two lines ( p = 0.01) were statistically significant lower in endoscopic cyclophotocoagulation group. Conclusion: This study demonstrates that both transscleral cyclophotocoagulation and endoscopic cyclophotocoagulation are effective at decreasing intraocular pressure. However, transscleral cyclophotocoagulation is related to more complications than endoscopic cyclophotocoagulation, whereas endoscopic cyclophotocoagulation shows lower intraocular pressure decrease than transscleral cyclophotocoagulation.

ABSTRACT Objective To assess the clinical outcomes in ectatic corneas following accelerated transepithelial cross-linking (CXL) over 1 year of follow-up. Materials and methods Twenty-one eyes diagnosed with progressive corneal ectasia (19 keratoconus, 2 post-laser in situ keratomileusis ectasias) in 14 patients aged between 26 and 69 years were enrolled. All cases were treated with accelerated transepithelial CXL using the Avedro KXL® system (Waltham, MA, United States). Changes at visual, refractive, corneal topographic, and corneal aberrometric level were evaluated over a 12-month follow-up period. The demarcation was also determined using optical coherence tomography (OCT). Results The mean depth of the demarcation line measured by OCT was 202.72 µm, varying between 153 and 230 µm. One month postsurgery, a change was noted at the limit of statistical significance in sphere (p = 0.05) and in spherical equivalent (p = 0.05). Likewise, a statistically significant difference was observed in corrected distance visual acuity (CDVA) (p = 0.01). There were no significant changes in either visual acuity or refraction between 1 and 6 months (p ≥ 0.35). Although changes in trend were observed in corneal topographic and aberrometric parameters after surgery, none reached statistical significance (p ≥ 0.08). A significant change was observed only in astigmatism of the posterior surface between 1 and 12 months (p = 0.02). Conclusion Accelerated transepithelial CXL may be a useful technique for the management of progressive corneal ectasia, as it is able to maintain the topographic and aberrometric profile of the cornea with no significant changes. Longer-term studies are required to confirm this finding How to cite this article Piñero DP, Artola A, Ruiz-Fortes P, Soto-Negro R, Pérez-Cambrodi RJ.

Importance: This study shows that a newer long-arc length intrastromal corneal ring segment is efficient and safe for keratoconus treatment. Background: To evaluate visual, tomographic results and complications of a 320-degree intrastromal corneal ring segment implantation with the femtosecond laser for keratoconus treatment. Design: A prospective, nonrandomized, and interventional study. Participants: A total of 34 eyes of 31 patients diagnosed with keratoconus were enrolled. Methods: Patients were divided into two groups based on the strategy used for 320-degree intrastromal corneal ring segment thickness selection. In one group, this selection was based on spherical equivalent (SE group) and in the other on the mean asphericity (Q group). The uncorrected and corrected distance visual acuities, spherical equivalent, K1, K2, Km, Kmax, and mean asphericity ( Q) on corneal tomography were evaluated preoperatively and at 3 and 6 months postoperatively. For astigmatism improvement, we analyzed the corneal tomographic vectorial astigmatism change preoperatively and at 6 months postoperatively. The mean follow-up period was 6.63 ± 0.96 months. Results: The mean uncorrected distance visual acuity and corrected distance visual acuity improved with a significant spherical equivalent improvement ( p < 0.05), with no differences between the 320-degree intrastromal corneal ring segment groups. All corneal tomographic parameters improved significantly ( p < 0.05) between the preoperative and postoperative intervals, with a significant better performance when we used spherical equivalent for the 320-degree intrastromal corneal ring segment thickness selection. Finally, the mean vectorial corneal tomographic astigmatism significantly improved after 6 months, again with no differences between groups. Conclusion: This study suggests that implanting a 320-degree intrastromal corneal ring segment is a safe and effective procedure for treating patients with keratoconus. It also suggests that for thickness selection spherical equivalent is the better strategy.

We assessed the outcomes of the use of anterior chamber foldable lens for unilateral aphakia correction at the University Teaching Hospital of Yaounde. In this retrospective, non-comparative, consecutive case series study, we reviewed the records of patients who underwent an operation for aphakia correction by the means of injection of an angular supported foldable lens between January 2009 and December 2011 in the University Teaching Hospital Yaounde. Student's paired t-test was carried out to compare preoperative and postoperative visual acuity (VA) and intraocular pressure (TOP). P-values less than 0.05 were considered statistically significant. Twenty-one patients were included in the study; twelve were male (57.1%) and nine were female (42.9%). The mean age was 55.38 ± 17.67 years (range 9–75 years). The mean follow-up duration was 5.95 ± 3.14 months (range 2–12 months). The mean logMAR visual acuity was 1.26 ± 0.46 pre-operatively and 0.78 ± 0.57 post-operatively ( P = 0.003). The change in intraocular pressure was not statistically significant. Complications included intraocular hypertension (over 21 mmHg) in 3 patients (14.3%) and macular edema, pupillar ovalization, and retinal detachment in one patient each. The results indicate that injection of an angular support foldable lens in the anterior chamber is a useful technique for the correction of aphakia in eyes without capsular support. More extended follow-up, however, and a larger series of patients are needed to ascertain the effectiveness and safety of this procedure.

Aim: To evaluate the effect of phacoemulsification with intraocular lens implantation in eyes with pre-existing trabeculectomy.Methods: This prospective single-center clinical study evaluated intraocular pressure in 60 eyes of 60 patients who underwent phacoemulsification and implantation of a foldable intraocular lens after a previous successful trabeculectomy. Patients who had a trabeculectomy more than one year prior to the study were included. Intraocular pressure, number of antiglaucoma medications, bleb appearance, and visual acuity were recorded preoperatively, and at each follow-up examination and 12 months after phacoemulsification.Results: The mean intraocular pressure before phacoemulsification was 12.42 mmHg (SD, 4.60 mmHg), which increased to 14.98 mmHg (SD, 4.18 mmHg), 14.47 mmHg (SD, 3.58 mmHg), 15.44 mmHg (SD, 3.60 mmHg), and 15.71 mmHg (SD, 3.47 mmHg) after one, three, six, and 12 months, respectively. At each follow-up visit, the mean IOP was significantly higher than the preoperative value (p < 0.001, p = 0.015, p ≤ 0.001, and p = 0.001 at month one, three, six, and 12, respectively). The mean preoperative best-corrected visual acuity was 0.98 logMAR (SD, 0.44 logMAR) and the mean postoperative best-corrected visual acuity at 12 months was 0.20 logMAR (SD, 0.21 logMAR) [p = 0.0001]. The mean preoperative number of antiglaucoma medications used was 0.57 (SD, 0.63), which increased to 0.65 (SD, 0.63 ), 0.70 (SD, 0.72 ) 0.68, (SD, 0.70), and 0.67 (SD, 0.77 ) at one, three, six, and 12 months, respectively, but there were no statistically significant differences. Bleb size decreased clinically after phacoemulsification. Nineteen of 60 eyes (32%) developed fibrosis of bleb with decreased bleb size.Conclusion: Phacoemulsification with intraocular lens implantation significantly increased intraocular pressure and increased the number of antiglaucoma medications in eyes with pre-existing functioning filtering blebs.

Diode Laser Cyclophotocoagulation

Purpose: To evaluate the intermediate-term efficacy and safety of micropulsed diode laser cyclophotocoagulation in recurrent pediatric glaucoma. Patients and Methods: A prospective interventional study included children <16 years old diagnosed with recurrent glaucoma, attending Mansoura University, during the period from July 2017 to November 2017. Micropulsed diode laser sessions were performed in all the cases. The main outcome was the intraocular pressure reduction with monitoring of complications as secondary outcome. The mean follow-up period was 15.08 ± 1.1 (mean: 12–16) months. Results: A total of 36 eyes of 29 patients were included (62% males) with median age of 24 months. Primary congenital glaucoma represented 47.2% of the initial diagnoses. At the 15th month, the mean intraocular pressure dropped significantly from 37.5 ± 11.3 mmHg at baseline to 20.03 ± 2.7 mmHg (p < 0.001) with 37.15% reduction. The mean number of glaucoma medications decreased significantly from 2.6 ± 0.5 pretreatment to 1.7 ± 0.6 at the 15th month (p < 0.001). A total of 24 eyes (66.7%) required second session of treatment with mean number of 1.7 ± 0.5 sessions per eye. The cumulative probability of qualified success was 69.4%, 58.3%, 52.8%, 47.2%, and 41.7% at 1, 3, 6, 12, and 15 months after treatment. Qualified success was achieved in 61% at 15 months without statistically significant difference between the initial diagnoses (p = 0.61). None of the eyes developed any major ocular complications throughout the follow-up period. Conclusion: Micropulsed diode laser was proved to be a safe approach with relative effectiveness in controlling intraocular pressure in children with recurrent glaucoma.

Aim To evaluate the long-term outcomes of corneal cross-linking (CXL) in patients with progressive keratoconus. Method In this retrospective non-comparative study, forty-five eyes of 31 patients with progressive keratoconus were treated with 30 min “epi-off” corneal cross-linking. The visual, refractive, topographic and tomographic outcomes were evaluated preoperatively and at least 10 years after cross-linking. Results Ten years post-corneal cross-linking, the mean anterior maximum keratometry decreased (−2.10 ± 3.25 D, P = 0.0001). Conversely, the posterior maximum keratometry increased (6.38 ± 9.79 D, P = 0.065). Both uncorrected and corrected distance visual acuity improved (LogMAR −0.08 ± 0.30) and (LogMAR −0.05 ± 0.21), respectively (P > 0.05, both). A statistically significant hyperopic shift was observed postoperatively (0.70 ± 1.31 D, P = 0.0009). The anterior topographic cylinder values revealed no change (−0.17 ± 1.31 D, P = 0.3), whereas the mean posterior cylinder values decreased (absolute value increased) significantly compared to baseline from −1.31 ± 0.97 D to −1.82 ± 1.78 D, (P < 0.05). The minimum corneal thickness values decreased significantly (−35.11 ± 48.63 µm, P = 0.0001). Four eyes (8.8%) showed more than 1 D increase in the anterior maximum keratometry. Conclusion This protocol and duration of Epi-off corneal cross-linking was found to be effective in halting keratoconus progression over the follow up period (10 years). Anterior corneal flattening and a hyperopic shift were observed. A statistically significant increase in the posterior corneal cylinder was observed. Although, not reaching statistical significance, the logMAR uncorrected and corrected visual acuity were improved.

Purpose: To evaluate the outcomes of a new antiglaucoma surgical method, a modification of the standard deep sclerectomy, the penetrating deep sclerectomy. Participants: Patients with medically uncontrolled primary open-angle glaucoma or pseudoexfoliative glaucoma were prospectively, in a consecutive way, enrolled in this study. Methods: The study was conducted in Glaucoma Unit, Department of Ophthalmology, University of Hospital of Alexandroupolis, Greece, in 29 eyes of 29 patients. In a fornix-based surgical procedure, all eyes underwent the proposed penetrating deep sclerectomy (deep sclerectomy plus trabeculectomy) with the use of mitomycin C applied intraoperatively (0.2 mg/mL for 2 min). The follow-up period was 3 years. Ocular examination was conducted before the operation and at 1, 3, 6, 12, 18, 24, and 36 months postoperatively. Results: The average reduction in intraocular pressure at the end of follow-up was 11.24 (57.88%). The complete success rate (intraocular pressure ⩽21 mm Hg without medication) after 3 years was 58.6%. The qualified success rate (intraocular pressure ⩽21 mm Hg without or with medication) was 75.86%. Postoperatively, the mean number of medication dropped from 3.75 ± 0.89 to 0.89 ± 0.98. Low postoperative complications were recorded. Conclusion: During the 3-year follow-up period, penetrating deep sclerectomy presented very positive outcome. The addition of a controlled perforation of the trabeculo-Descemet’s membrane in deep sclerectomy, playing the role of an early goniopuncture, seems to ensure a satisfactory outcome and is not associated with additional complications.

Objectives: To assess the myringoplasty graft take rate, comparing two methods of post-operative ear packing: bismuth iodoform paraffin paste (BIPP) gauze versus tri-adcortyl ointment (TAO).Methods: A retrospective study of patients who had undergone myringoplasty at our department within a three-year period was undertaken. Data, including age, site and size of perforation, grade of surgeon, surgical approach, use of post-operative ear dressings, complications, and audiometric outcome, were collected from the patient notes and analysed. The overall success rate of the operation (with success being defined as an intact tympanic membrane at six months) was noted.Results: One hundred and seventy myringoplasties were performed over the study period, but data were complete on 154 patients and these constituted the study population. Age ranged from nine to 71 years (mean age 34 years) and the mean follow-up period was seven months. Consultants performed 62 per cent of the operations, with an 85 per cent success rate, whereas trainees performed the remaining 38 per cent, with a success rate of 73 per cent (p=0.059). The overall success rate was 80 per cent; 79 per cent for BIPP and 83 per cent for TAO (p=0.55), and 87 per cent for small perforations and 75 per cent for subtotal perforations (p=0.22). There was audiometric improvement in 74 per cent of cases.Conclusion: We found no significant difference in outcome between patients packed with TAO and BIPP. Packing with TAO is therefore a suitable alternative to BIPP gauze ear dressing following myringoplasty.
