Selective Endothelialectomy in Peters Anomaly: A Novel Surgical Technique and Its Clinical Outcomes in Children

imagePurpose:

This study describes the surgical outcomes of selective endothelialectomy in Peters anomaly (SEPA), a relatively new technique to manage Peters anomaly (PA).

Methods:

This study included 34 eyes of 28 children who had a visually significant posterior corneal defect due to PA and underwent SEPA between 2012 and 2019. A selective endothelialectomy from the posterior corneal defect was performed while preserving Descemet membrane. The primary outcome measure was the resolution of corneal opacification. The secondary outcome measures were functional vision, complications, and risk factors for failure.

Results:

At a mean postoperative follow-up of 0.96 ± 0.20 years, 29 eyes (85.3%) maintained a successful outcome. Mean preoperative and postoperative best-corrected visual acuities were 2.55 ± 0.13 and 1.78 ± 0.13 (P

Comparative In Vitro Activity of New Lipoglycopeptides and Vancomycin Against Ocular Staphylococci and Their Toxicity on the Human Corneal Epithelium

Purpose:

The purpose of this study was to assess the potential of new lipoglycopeptides as novel topical therapies for improved treatment of recalcitrant ocular infections. We evaluated the in vitro antimicrobial activity of oritavancin, dalbavanci…

Corneal and Whole-Eye Higher Order Aberrations Do Not Correlate With Ocular Residual Astigmatism in Prepresbyopic Refractive Surgery Candidates

imagePurpose:

Ocular residual astigmatism (ORA) is the proportion of manifest astigmatism that is not explained by anterior corneal astigmatism. The role of higher order aberrations (HOAs) in the level of ORA has not been profoundly studied. The purpose of this study was to evaluate the effect of different corneal and whole-eye HOAs on levels of ORA using a multivariate modeling approach.

Methods:

This is a retrospective analytical study including a sample of healthy refractive surgery candidates. One eye of every patient was randomly selected. A total of 294 eyes from an equal number of patients were included. Corneal and whole-eye HOAs were measured with a Pentacam AXL Wave, and subjective manifest refraction was taken. Astigmatism values were converted into power vectors and ORA was calculated. The Spearman rank-order correlation was initially used to explore correlation between HOA and ORA. All variables with a P value under 0.10 were included into a multiple linear regression model to explore this correlation adjusting for confounding variables.

Results:

The mean age was 28.81 ± 5.40 years. Simple bivariate correlation was significant for root mean square (RMS) total, RMS lower order aberrations, RMS HOAs, defocus, and vertical astigmatism. After being included into a multivariate regression model adjusting for confounding variables, the only variable that was significant was RMS total [F(3, 282) = 78.977; P

Descemet Membrane Endothelial Keratoplasty and Triple Descemet Membrane Endothelial Keratoplasty in Eyes With Macular Comorbidity

imagePurpose:

The aim of this study was to evaluate results after Descemet membrane endothelial keratoplasty (DMEK) and DMEK with cataract surgery (triple DMEK) in eyes with endothelial dysfunction and concomitant macular pathology.

Methods:

A monocentric, prospective clinical observational study of patients who underwent DMEK or triple DMEK surgery at the Department of Ophthalmology, University Hospital Düsseldorf, Germany, from June 2013 to February 2016 was conducted. Sex, age, best-corrected visual acuity (BCVA), central corneal thickness, endothelial cell density, and central retinal thickness in the 1 millimeter zone were analyzed.

Results:

A total of 209 eyes were included in the study. Forty-two eyes (20.1%) had vision-limiting concomitant maculopathies. These were age-related macular degeneration (n = 17, 8.1%), epiretinal gliosis (n = 13, 6.2%), chronic macular edema (n = 7, 3.3%), macular holes (n = 3, 1.4%), and macular scarring (n = 2, 1.0%). BCVA significantly increased in patients without maculopathy from 0.6 ± 0.33 logMAR to 0.1 ± 0.15 logMAR (P
