Purpose: Lower eyelid management is challenging. The conchal cartilage is often considered a spacer of choice for treating lower eyelid retraction. However, dermis graft has also recently been shown to be a viable spacer. The aim of this study was to compare the efficacy of dermis graft to that of conchal cartilage graft in this indication. Methods: A retrospective comparative study was conducted in patients who underwent lower eyelid lengthening with autologous dermis graft (group 1) or autologous conchal cartilage graft (group 2). The main outcome measure was the reduction in inferior scleral show (ISS) assessed by three independent masked surgeons. Secondary outcome measures was the assessment of lagophthalmos and corneal keratitis. Complications were also recorded. Results: Twenty-five eyelids of 23 patients were included: 11 and 14 eyelids, respectively in group 1 (dermis graft) and group 2 (conchal cartilage graft). Patient mean follow-up was 12.3 (±12.5) and 7.1 (±7.7) months, respectively. No statistical differences in postoperative ISS reduction, lagophthalmos and exposure keratitis was observed ( p = 0.540, p = 0.946, p = 0.934, respectively). Three patients experienced a grade I Clavien–Dindo complication in group 1 and one patient experienced a grade II complication in group 2 ( p = 0.540). Conclusion: Autologous dermis grafts and conchal cartilage grafts provide favorable outcomes without major complications.

To compare safety and efficacy of intravitreal therapy between anti vascular endothelial growth factor (Anti-VEGF) Ranibizumab and biosimilar Razumab in diabetic macular oedema (DME), wet age related macular degeneration (AMD) with choroidal neovascular membrane (CNVM) and retinal vein occlusion (RVO). Prospective comparative study involved 60 eyes of 56 adults, randomized into 2 groups from September 2016 to November 2017. Group 1 (n=30) received Ranibizumab (0.5mg in 0.05ml) and group 2(n=30) Razumab (0.5mg in 0.05ml). Initial loading dose of one injection given to all subjects and a pro re nata schedule followed thereafter. Patients received maximum of 3 injections and were followed up to 12 weeks. Best corrected visual acuity (BCVA) and central foveal thickness (CFT) were considered for the primary outcome and adverse drug reactions (ADR) was considered in the secondary outcome. A p value of less than 0.05 was considered statistically significant. The 12-week mean BCVA in group 1 was 0.39 (+-0.24); and in group 2 was 0.53 (+-0.37), which had improved significantly from baseline (group 1 p= 0.007, group 2 p <0.001). Inter group comparison was statistically insignificant (p=0.249). The 12 weeks mean CFT in group 1 was 308 (+-107.26) ; and group 2 was 307.60 (+- 87.15), which had improved significantly from baseline in both groups (p <0.001). Inter group difference was statistically insignificant (p=0.544). One patient in group 2 experienced an ADR (p=0.305). In this study both Ranibizumab and Razumab were safe and efficacious.

Purpose. To compare the capsule edges ultrastructure obtained by two femtosecond laser-assisted cataract surgery (FLACS) platforms and manual continuous curvilinear capsulorhexis (CCC) using scanning electron microscopy (SEM). Setting. Eye Clinic, University of Trieste, Italy. Design. Experimental comparative study. Methods. 150 anterior capsules were collected and divided into three groups as follows: Group 1 (50 capsules) obtained with manual CCC, Groups 2 and 3 (each with 50 capsules) obtained with the Catalys Laser and the LenSx Laser, respectively. All samples were imaged by means of SEM and regularity of the cut surface, and thickness of the capsule edge were evaluated and compared. Results. All femtosecond laser (FSL) capsules were perfectly circular, whereas some alteration of the circular shape was observed in the manual ones. Group 1 showed a smooth and regular capsule edge without any surface irregularity, conversely Groups 2 and 3 showed postage-stamp perforations on the capsule edge. The cut surface irregularity value in Group 2 was 1.4 ± 0.63, while it was 0.7 ± 0.49 in Group 3 (p<0.05). Group 1 had a significantly lower thickness of the capsule edge than the FSL groups (p<0.05). No statistically significant difference in the capsule edge thickness between the FSL groups was found (p=0.244). Conclusions. Despite the presence of slight cut surface irregularities, both FSL capsulotomies showed a better geometry and circularity than the manual ones. Capsulotomy specimens obtained using both FSL capsulotomies showed laser-induced alterations of the capsule edge when compared with smooth and regular edges obtained using manual CCC.

Objective: to evaluate the effectiveness of an esophagoprotector in reducing the risk of recurrent symptoms of gastroesophageal reflux disease (GERD) in patients who requiring temporary cancellation of therapy with proton pump inhibitors (PPIs). Material and methods. For the prospective comparative study there were selectively chose patients who had been taking PPIs for a long time (at least one month) for the underlying disease and who required temporary discontinuation of antisecretory therapy due to objective medical reasons. The study included patients with endoscopically and/or pH-metrically verified GERD, as well as histologically verified Barrett's esophagus. In the process of randomization of patients, two equal groups were formed, depending on the therapy received at the time of PPI withdrawal: group 1 received antacids on demand, group 2 received antacids on demand, as well as the esophagoprotector Alfasoxx at a dose of 10 ml four times a day (after each meal and at night). The follow-up period was two weeks. The patients recorded episodes of heartburn in their personal diaries. Results. The study included 60 patients (28 men and 32 women). The average age of the examined patients was 43.1 ± 5.3 years. By the end of the two-week follow-up period, the frequency of recurrent symptoms in group 1 was 36.7%, while in group 2 it was 13.3%. The use of the esophagoprotector Alfasoxx contributed to the significant regression of the risk of heartburn recurrence (odds ratio 0.2657; 95% confidence interval (CI) 0.07328-0.9637; p = 0.0438) in comparison with the group of patients who received only antacids in the on-demand mode. When analyzing the population of patients who had relapsed symptoms, it was demonstrated that the average number of heartburn episodes in group 1 was 6.18 (95% CI 4,1930-8,1706), and in group 2 – 4.50 (95% CI 0,7121-8,2879). Conclusion. This prospective comparative study demonstrated that the use of the esophagoprotector Alfasoxx helps to reduce the risk of relapse of GERD symptoms in patients requiring temporary cancellation of PPI therapy.

Introduction: Clubfoot is a common congenital deformity with incidence of1-6.8/1000 live births. Ponseti method is currently the gold standard for treatment of clubfoot which conventionally involves weekly plaster changes. A prospective comparative study was carried out at our hospital where we compared one group with weekly plaster change to other group with twice weekly plaster change, using the classical Ponseti protocol of manipulation. A total 50 feet (36 children ), divided into two Methods: groups, were randomly allocated to either Group 1 – 25 feet(accelerated Ponseti) or Group 2 – 25 feet (standard Ponseti). Group 2 underwent serial manipulations and casting once a week and Group 1 received manipulations and castings twice a week. Pirani score was documented at the time of presentation, after each cast, and at the time of removalof nal cast to assess the success of treatment ( Pirani score ≤1). A tota Results: l 43 feet (29 patients) underwent the entire course of treatment, while 7 patients discontinued the treatment during the course of the study. 14 patients, i.e, 21 feet were treated with Accelerated Ponseti Protocol (APP),i.e Group -1, and 15 patients, i.e, 22 feet were treated with Standard Ponseti Protocol (SPP), i.e Group-2. Mean duration of treatment from the rst cast to tenotomy in the accelerated ponseti protocol group was 20.57 ± 4.5 days (ranging from 12 to 29 days), and in standard ponseti protocol group was 39.66 ± 6.9 days (ranging from 29 to 51 days). Conclusion: Both the methods proved to be equally efcacious for the management of clubfoot in our study. However, the accelerated method had an overall shorter treatment duration making it convenient for the parents. As the patient is under direct observation of surgeons, complications, in any, are detected early and easily. Overall, the accelerated technique is more practical, benecial, and equally efcacious as standard ponseti technique, providing a more rapid correction of the deformity.
