Purpose. To report the surgical treatment and follow-up of tumors of the anterior uvea and epithelial cysts of the anterior chamber in 4 patients submitted to block excision and tectonic corneal graft between 2008 and 2012. Methods. This is a retrospective, nonrandomized case series. Two patients were affected by anterior uveal malignant melanoma, and 2 patients were referred to us for large epithelial iris cysts with anterior chamber angle involvement and partial corneal failure. A simultaneous block removal of the lesion and adjacent iris, cornea (when necessary), ciliary body, and sclera was performed; the resulting defect was covered by a tectonic whole thickness corneal graft. Follow-up ranged from 2 to 7 years (mean time: 5 ± 1.6 MD). Results. Local control of malignant melanoma was observed during the follow-up, but cataract surgery was planned in both patients and pars plana vitrectomy for vitreous hemorrhage occurred in one case. No recurrence of cysts was detected. After iris cysts excision, a planned second-time surgery was necessary in one patient: optical penetrating keratoplasty, centered on the visual axis, implantation of one refractive IOL (intraocular lens) in the bag, and one cosmetic IOL in the sulcus, to restore the iris diaphragm. Conclusions. Block excision followed by the tectonic corneal graft seems to be the treatment of choice for selected cases of epithelial cysts of the anterior chamber and anterior uvea melanomas with epibulbar extension. Further surgery, as a second step, could be required to improve functional results of this challenging technique.

Purpose. The black iris-lens diaphragm (ILD) can be used in the treatment of traumatic aniridia and aphakia. The aim of our study was to show postoperative functional and anatomic results and complications in a small case series. Methods. We retrospectively analyzed the files of 16 patients managed with a black ILD or a sole iris diaphragm in the period 1994–2007. Four of them were female and 12 were male. The mean age of the group was 50±17 years. At the time of the implantation, all of the eyes had already undergone primary surgical repair. Results. The preoperative best-corrected visual acuity in half of the patients was ≥0.1 and remained stable after the first postoperative year. During the follow-up years, one eye developed a subluxation of the implant and one eye an anterior chamber hemorrhage. At the same time, out of 8 eyes carrying a silicone tamponade in the vitreous cavity, silicone oil entered the anterior chamber in 3 cases. In one case, enucleation was undertaken due to phthisis. Conclusions. In the case of severely traumatized eyes with aniridia and aphakia, the implantation of a black ILD can have a positive effect on functional and anatomic stabilization.

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.

The aim of this study was to verify the validity, feasibility, and the functional results, by uroflowmetry, of Tubularized proximallyincised plate technique in selected case of distal/midshaft hypospadias. Out of 120 patients scheduled to undergo TIP (or Snodgrass) procedure, 23 were selected between January 2013 and January 2016 (19.1%). This case series comprised 16 patients with distal and 7 with midshaft hypospadias. Mean age at surgery was 2.9 years. The inclusion criteria were a deep and wide glandular groove and a proximal narrow urethral plate. The procedure was carried out as described by Snodgrass but the incision of the urethral plate, including the mucosal and submucosal tissue, was made only proximally, between the original meatus and the glandular groove in no case extending to the entire length of the plate. Postoperatively a foley catheter was left in place from 4 to 7 days. Uroflowmetry was performed when the patients age ranged from 2.5 to 5.7 years (mean age 3.11 years and mean follow-up 1.8 years, body surface 2). No patient presented fistulas nor perioperative complications. At uroflowmetry, eighteen patients presented values above the 25<sup>th</sup> percentile and 5 showed a borderline flow. All patients in this group remained stable without urinary symptoms. In selected cases, the tubularized proximally-incised plate yields satisfactory cosmetic and functional results for the treatment of midshaft proximal hypospadias. A long-term follow-up study is needed for further evaluation. Patient selection is crucial for the success of this technique.

Physical Impact

Objective: Impingement syndromes are recognized as an important cause of chronic ankle pain, which results from the entrapment of an inflamed soft-tissue component between the osteophytes. The predominant site of occurrence is the anterolateral aspect of the ankle for soft-tissue impingement, and anteromedial aspect for bony impingement. Symptoms related to the physical impact of bone or soft-tissue pain often result in limited ankle range of motion. Methods: We conducted a retrospective study of 34 patients (34 ankles) with anteromedial bony impingement. All patients underwent arthroscopy, with a mean follow-up of 34 months. Results: All osteophytes were removed, and the ankle range of motion improved. The AOFAS score improved from 73 preoperatively to 95 postoperatively. Conclusion: The arthroscopic removal of the anteromedial osteophytes of the ankle had excellent functional results. It is an effective procedure that allows rapid patient recovery.

Background: The treatment of displaced intra-articular calcaneal fractures remains a challenge and the optimal approach is still controversial. The main reason to avoid the extended lateral approach is the high complication rate due to wound healing problems. We report on 16 years of experience with a standardized limited open reduction and internal fixation technique. Methods: Between 2001 and 2017, we prospectively followed 240 consecutive patients operatively treated for a displaced intra-articular calcaneal fracture. Patients with open, multiple, bilateral, extra-articular, and Sanders IV fractures and those lost to follow-up were excluded. A lateral subtalar approach was used, with a cast for 8 weeks and full weightbearing allowed after 12 weeks. Follow-up examinations were scheduled until 24 months. Subjective and clinical assessment included gait abnormality, subtalar and ankle range of motion, and stability and alignment. The American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score was calculated. Alignment was analyzed on standard radiographs. In total, 131 patients were excluded. The remaining 109 patients were followed for a minimum of 24 months (34.4 ± 14.2 [range, 24-102] months). Results: The mean AOFAS score was 87 ± 13 (range, 32-100). “Excellent” and “good” results, as well as hindfoot motion with “normal/mild” and “moderate” restrictions, were seen in 80% of patients. Early reoperations were performed for insufficient reduction (2 patients), delayed wound healing (debridement, 3 patients), and hematoma (1 patient). Late revisions were arthrodesis (3 patients), medializing calcaneal osteotomy (1 patient), and implant removal (53 patients; 49%). Conclusion: The presented approach has remained unmodified for 16 years and resulted in consistently good functional results. The main disadvantage was the high rate of heel screw removal. Level of Evidence: Level IV, retrospective case series.

Aim: To assess long-term anatomic and functional outcomes of early lens-sparing vitrectomy (LSV) for stage 4A retinopathy of prematurity (ROP) in infants with aggressive-posterior ROP (AP-ROP) which progressed to retinal detachment despite laser treatment. Methods: Chart review of infants who underwent early 25-gage LSV for stage 4A ROP. Outcomes were anatomic success, mean visual acuity (VA), development of postoperative complications, and refractive changes. Follow-up examinations were performed at 1, 3, 6, 12, and then every 6 months. Results: Ten eyes of seven preterm infants who underwent LSV were included. Mean follow-up was 36 ± 13.4 months and mean postmenstrual age (PMA) at last follow-up was 37 ± 13.7 months. Mean gestational age (GA) and weight at birth was 26 ± 1.4 weeks and 639 ± 180 g. Two eyes had vitreous hemorrhage 4 and 14 days after surgery, respectively. At last follow-up anatomic success was 100%, mean VA was 20/80 and eight eyes (80%) had high myopic refractive correction (mean spherical equivalent –11.25 D). Conclusion: Early LSV for stage 4A ROP with AP-ROP and progression to retinal detachment is efficacious in terms of anatomic and functional outcomes. Anatomic success is associated with visual improvement despite possible myopic refraction changes during follow-up.

Chiari Pelvic Osteotomy

Background: The modern indications for Chiari pelvic osteotomy (CPO) have narrowed and the number of such operations performed has diminished markedly. So far published long-term experience with CPO indicate the fact that in selected patients satisfactory functional results can be achieved. The aim of this study was to investigate the parameters which influence CPO survival and its conversion into total hip arthroplasty (THA). Methods: This is a single-centre retrospective case-series study. In the period from 1976 to 2012, it included 172 CPO in 158 patients. Of those, in 43 patients (48 hips) the follow-up was discontinued, leaving 115 patients (124 hips) for final analyses. The median age at the time of the surgery was 34 years, and the mean duration of the follow-up was 19 years. Results: In 115 patients (124 CPO) included in the study, a total of 51 THA was performed in 49 patients. The median period between CPO and THA was 14 years. Conclusion: Supporting our results, we suggest that CPO should still be indicated in a selected group of younger patients even with advanced stage of hip osteoarthritis who prefer a joint-conserving procedure and consent to a predicted less optimal outcome.

Abstract Introduction It has been shown that direct fixation of the posterior malleolus improves functional outcomes. Our aim was to audit the functional outcome of patients with these fractures which were fixed with an isolated posterolateral approach. Method A consecutive case series of patients who underwent direct fixation of the posterior malleolus using a posterolateral approach between 20/12/2012 and 23/1/2020 was identified. Fractures were classified according to Mason and Molloy classification based on preoperative CT. Type 2a and 2b fractures were included. Functional outcome was assessed using Olerud-Molander score. Result 18 patients were included. Mean age at time of surgery was 52 years (range 20 to 75 years). 56% (n = 10) were female. Mean follow up was 18.1 months (range 4.2 months to 7.2 years). OMAS score for type 2a fractures (n = 9) was 71.1 (95% CI 65.3 to 77.0). OMAS score for type 2b fractures (n = 9) was 67.8 (95% CI 54.6 to 81.0). There was no significant difference between groups (p = 0.65). Conclusions Fixation of Mason and Molloy Type 2 fractures using an isolated posterolateral approach results in satisfactory functional results for the majority of patients. Further prospective comparative study is needed to identify which patients benefit most from alternative approaches.

Corneal Graft Failure

Tube shunts can be placed in the anterior chamber, the ciliary sulcus, or the pars plana. However, if the eye is phakic, the choice is limited to the anterior chamber; ciliary sulcus placement is likely to result in cataract formation, and pars plana placement will likely complicate removal of the cataract that will likely develop. Most corneal complications of tube shunt surgery result from tubes that are too anterior. Loss of vision may result due to these complications. If the tube is inadvertently inserted too close to the cornea, a loss of endothelial cells will result in edema and require transplantation to restore vision. Reported rates of corneal complications range from 2% to 33% and consist mostly of corneal edema/decompensation and corneal graft failure. In a cohort of patients implanted with the Ahmed™ Glaucoma Valve (New World Medical, Inc., Rancho Cucamonga, California), postoperative corneal abrasions occurred in 5 of 60 (8%) eyes. Another study reported the rate of corneal drying/dellen later in the postoperative course (8 of 59 eyes; 13.6%). Contact between the tube and the cornea has been noted at a rate of up to 5%. As the rate of tube shunt implantation has increased, the incidence of corneal edema in patients with tube shunts has also increased. Some of these cases develop corneal opacification with decreased vision and may require corneal transplantation to clear the visual axis. One large study of patients with Ahmed tube shunts (159 eyes total) reported corneal graft failure resulting in repeat penetrating keratoplasty (PKP) in 11 of 31 (35%) eyes with corneal grafts. Improper anterior chamber tube entry may damage the cornea. If the entry angle is not parallel to the iris and aims anteriorly, the needle used to create the tunnel may tear or detach Descemet’s membrane. Entry through the cornea (rather than the sclera) may also predispose to epithelial downgrowth or tube extrusion. To avoid such a complication, fullthickness entry into the anterior chamber should be as far posterior as possible.

Purpose: To analyse the outcomes of sutureless and sutured scleral fixated intraocular lenses (SFIOL) in paediatric population. Setting: Vitreoretina department of a tertiary eye care institute in Southern India Design: Retrospective case series Methods: Data were collected from January 2010 to December 2018 for children less than 18 years of age, based on the following parameters: demographics, pre-operative characteristics, duration between aphakia and surgery, previous amblyopia treatment, the uncorrected (UCVA) and the best corrected visual acuity (BCVA) at baseline and, 1,6 and 12 months or final visit. Early and late post-operative complications along with details of any resurgery was recorded. Results: The study included 45 eyes of 43 patients. The mean age when children became aphakic was 8.8±3.6 years and the mean age at SFIOL implantation 10.1 ± 3.9 years. Sutureless SFIOL was performed for 36 (80%) eyes. The improvement in UCVA was statistically significant at 1-month follow up. Transient hypotony (n = 3), vitreous hemorrhage ( n = 7) and raised IOP ( n = 4) were the most observed early post-operative complications, while haptic exposure or disinsertion ( n = 4, 9%) was a delayed postoperative complication. The mean spherical equivalent at the last follow up was 1.96 ± 0.83D and mean postoperative cylinder 2.32 ± 1.3D. The children were followed up for a mean duration of 20 ± 21.7 months. History of previous vitrectomy was found to be associated with two line reduction in UCVA (95% CI = 0.03–0.5 logMAR, p = 0.008). Conclusion: SFIOLs- sutured and sutureless; both were suitable for the rehabilitation of paediatric aphakia. Sutureless scleral fixation is a safe alternative for children but prospective studies with longer follow-up are needed.
