Dry eye disease, Schirmer I test, clinical tests, large population of patients, tear production levels
Dry eye disease (DED) is multifactorial, caused by an alteration in the quality or quantity of tear film’s three layers. Several tests are available for diagnosis. The aim of this study was to determine if the Schirmer test (ST) could...
Corneal suture sample evaluation
This is a prospective study of 35 patients’ suture samples taken from a tertiary cornea clinic, Miami, Florida, with a history of penetrating keratoplasty. The aim is to study the relationship between corneal suture bacteriology, biofilm and the clinical setting,...
Results of corneal cross-linking in very steep corneas
Corneal cross-linking (CXL) has been shown to be a safe and valid treatment option for progressive keratoconus and have shown an arrest of progression with a low failure rate of 0% to 2.8% in mild to moderate keratoconus. A Kmax...
Corneal cross-linking for treatment of corneal ulcers
This was an observational cohort study looking at the usefulness of photo activated chromophore for infectious keratitis-corneal collagen cross-linking (PACK-CXL) in reducing the time to heal in suppurative corneal ulcers. This study, conducted in a tertiary care centre in South...
Outcomes of corneal cross-linking in paediatric patients compared to fellow untreated eyes
This retrospective cohort study evaluated long-term visual, refractive, topographic and safety outcomes of corneal cross-linking (CXL) in patients younger than 18-years-old with keratoconus. The study included all consecutive paediatric patients who underwent epithelium-off CXL treatment for keratoconus at the study...
Corneal thickness in patients with diabetic peripheral neuropathy
This cross-sectional study assessed corneal thickness in association with diabetic peripheral neuropathy (DPN) severity. The study also tried to identify the layer of the cornea most affected by DPN status. Performed at the University of Michigan the study included three...
Microbial keratitis in corneal grafts
The authors report a retrospective case series of 59 episodes of microbial keratitis identified in 41 eyes of 41 patients (39 penetrating keratoplasty (PKPs) and two deep anterior lamellar keratoplasty (DALKs)), from a total of 759 consecutive corneal grafts identified...
Long-term corneal crosslinking results in paediatric eyes
This prospective longitudinal study examined patients 18 years of age or less with progressive keratoconus, who underwent corneal crosslinking and completed 10 years of follow-up. Crosslinking protocol involved removal of epithelium, 10 minutes of riboflavin soaking, followed by 30 minutes...
Phakic iris clip lenses and endothelial cell loss
This retrospective observational study included long-term results on endothelial cell losses in highly myopic eyes, which underwent phakic iris-clip lens implantations. Included in the analysis were 113 eyes with mean preoperative spherical equivalent (SEQ) of -14.67 +/- 5.15 Diopters (D)....

MicroRNAs (miR) are small non-coding RNA that target mRNA for destruction. MiR target about 30% of the protein coding genes and fine tune their expression. MiR have been shown to be involved in several cellular processes including cell cycle, tissue...

The cornea is exposed to hypoxia under several conditions including sleep, inflammation and wound healing. Being an avascular tissue to maintain transparency, how the cornea homeostatic controls oxygen tension is important. To address this process two models were utilised; a...
Outcomes of hemi DMEK
This was a prospective, interventional case series of 10 eyes from 10 patients who underwent hemi-descemet membrane endothelial keratoplasty (hemi-DMEK) for Fuchs endothelial dystrophy. The surgical technique for hemi DMEK procedure was similar to the circular DMEK except that a...
