Purpose: To analize changing trends in indications and surgical techniques of corneal transplantation at an ophthalmological tertiary referral center in Colombia over a 7 year period. Methods: A retrospective analysis was performed of medical records from patients who underwent corneal transplantation surgeries at Fundación Oftalmológica de Santander (FOSCAL) in Bucaramanga, Colombia, between August 2004 and August 2011. Results: During this period from a total of 450 corneal transplants performed, we had access to 402 medical records (89.4%). The patients’ mean age was 55. Leading indications were: pseudophakic/aphakic bullous kerathopathy (PBK/ABK) (34.6%), corneal scar (15.7%), active infectious keratitis (14.4%) and keratoconus (12.7%). During the first period (2004-2007) PBK/ABK was the leading indication, followed by stromal opacities and keratoconus. During the second period (2008-2011) PBK/ABK remained the leading indication. Infectious keratitis, however, became the second most common indication. Stromal opacities and keratoconus, moved to third and fourth, respectively. All transplants performed in the first period (2004-2007) were penetrating keratoplasties. In the second period (2008-2011) 18.7% of the procedures were performed using the Descemet’s stripping automated endothelial keratoplasty technique (DSAEK). Conclusions: Similar to other international results, PBK/ABK was the leading indication for corneal transplantation at our institution. Keratoconus is becoming a less common indication for keratoplasty in our institution. Infectious keratitis remains a frequent indication for corneal transplantation in this geographical area. In our institution we started performing DSAEK in 2009, and it is emerging as the procedure of choice in corneal diseases that involve only the endothelial layers.

Background: There has been a sustained increase in the rate of caesarean section in the last few years around the world. Data regarding the current caesarean rate and the trends of its indications in eastern Nepal have not been estimated earlier. Aim: To assess the rate of caesarean sections and the varying indications for caesarean section in a tertiary referral center in eastern Nepal. Methods: All hospital deliveries that took place in BPKIHS between January 2006 and December 2007 were recorded to assess the caesarean section rate and its indications. Results: A total of 5330 deliveries were conducted in 2006. Likewise the total number of deliveries conducted in 2007 was 6634. In 2006 caesarean sections were performed in 28.6% (1524) of all patients. The rate of caesarean sections in 2007 increased and was 33.7% (2239). The most common indication for caesarean section was meconiumstained liquor, which constituted 23.4% (883). The next frequent indication was previous caesarean section, which accounted for 17.2% (650), followed by breech presentation in 11.1% (417), fetal distress in 9.6% (364), non-progress of labor in 7.2% (270), cephalopelvic disproportion in 6.2% (234, and placenta previa in 4.4% (165). Conclusions: There is a increasing trend of performing cesarean section in the tertiary referral center in east era Nepal. The most common indication for cesarean section is meconium-stained liquor.

AimTo determine the prevalence and clinical consequences of cytomegalovirus (CMV) DNA in the aqueous and corneal tissues obtained at the time of corneal transplantation to evaluate the diagnostic value of PCR analysis in identifying patients at risk of postkeratoplasty CMV endotheliitis.MethodsThirty patients who underwent corneal transplantation were included in 2011. The aqueous, excised recipient corneas and donor corneoscleral rims were analysed by PCR for the presence of CMV DNA. The medical records of the patients were retrospectively reviewed and linked with PCR results.ResultsCMV DNA was detected in three (10%) aqueous, eight (26.7%) recipient corneas and six (20.0%) donor corneas obtained during keratoplasty from the 30 patients. Postoperatively, four patients, who had CMV DNA in either aqueous (3) or recipient cornea (1), were diagnosed with CMV endotheliitis based on clinical features and repeat aqueous tapping for real-time PCR analysis. At the median 60.5 months follow-up, 8 (72.7%), including 4 with postkeratoplasty CMV endotheliitis, of the 11 patients with CMV positivity in any one sample had graft failure, while 9 (47.3%) of the 19 patients without evidence of CMV DNA experienced graft failure.ConclusionsWe found a relatively high prevalence of CMV DNA in the aqueous and corneas obtained during keratoplasty. All the patients who had CMV positivity in aqueous developed CMV endotheliitis postoperatively and experienced graft failure eventually. Aqueous tapping at the time of corneal transplantation for PCR analysis may help to improve the diagnosis and follow-up management of postkeratoplasty CMV endotheliitis.

Purpose. To analyze the indications and surgical procedures for repeat keratoplasty in eastern China from 2008 to 2019. Methods. This retrospective descriptive study included 418 eyes of 411 patients who underwent no less than 2 keratoplasties at the Eye, Ear, Nose and Throat Hospital of Fudan University from 2008 to 2019. Medical charts were reviewed. The primary indications for repeat keratoplasty, the reasons for regrafting, and the surgical techniques used in the treatment were collected and analyzed. Results. Among 418 eyes, 337 eyes (80.6%) had one repeat keratoplasty, and 81 eyes (19.4%) had multiple repeat keratoplasties (≥2 repeat keratoplasties). The median interval between the initial keratoplasty and the first repeat keratoplasty was 25 months, and that between two keratoplasties after the first repeat keratoplasty was 27.5 months. Infectious keratitis was the leading primary indication for single repeat keratoplasty (80 cases, 23.7%) and multiple repeat keratoplasties (19 cases, 23.5%). The second most common primary indication was bullous keratopathy for single repeat keratoplasty (49 eyes, 14.5%) and chemical injury for multiple repeat keratoplasties (14 eyes, 17.3%). The main reason for regrafting was allograft rejection (262 cases, 49.3%), followed by endothelial dysfunction (92 cases, 17.3%), and for vision improvement after tectonic keratoplasty (60 cases, 11.3%). Penetrating keratoplasty (PKP) was the major technique used in repeat keratoplasty (447 cases, 84.2%). However, Descemet stripping endothelial keratoplasty was more frequently used than PKP (72.4% vs. 27.6%, P < 0.001 ) in the treatment of failed endothelial keratoplasty. Conclusion. Infectious keratitis was still the leading cause of repeat keratoplasty in eastern China. Although PKP remains the major technique of repeat keratoplasty, the application of customized lamellar keratoplasty has greatly expanded in the last decade. Cautious selection of indications, surgical techniques, and timing for surgery is crucial for a good prognosis after repeat keratoplasty.

Introduction. During the past decade, novel techniques of corneal transplantation allowing faster and better restoration of vision have emerged. The present cohort study describes a shift of indications and techniques that has occurred in the field of corneal transplantation over a 17-year period in Greece. Methods. All patients undergoing keratoplasty between January 1999 and December 2015 at an academic tertiary referral center in Athens, Greece, were retrospectively reviewed. The annual incidence of keratoplasty indications and techniques was recorded and analyzed. Results. A total of 1382 keratoplasty procedures were included. Leading indications were bullous keratopathy (BK) (37.5%), followed by allograft rejection (17.7%), corneal scar (12%), keratoconus (KC) (10.3%), and Fuchs endothelial dystrophy (FED) (8.8%). A decreasing trend was observed for KC (P=0.009) and an increasing trend for BK (P=0.003) and FED (P=0.001). In 2015, the incidence of penetrating keratoplasty (PK) had decreased from 100% (1999 to 2009) to 21.4%; for cases with isolated pathology of the corneal endothelium, DSAEK was the preferred technique (59.8%), while the respective rate of DMEK was 18.8%. Conclusion. Herein, we observed an increasing trend of endothelial pathology among keratoplasty indications as well as a major shift in preferred techniques due to a wide adoption of the new EK procedures.
