Lamellar patch grafts utilising cornea remnants from DMEK/PKP
The authors retrospectively reviewed 23 lamellar patch grafts performed over a six-year period for tectonic indications in corneal thinning and perforations. The anterior stroma of corneal endothelium peeled for descemet membrane endothelial keratoplasty (DMEK) were used to prepare circular lamellar...
Hidden spread of sebaceous cell carcinoma
This was a review of 29 patients who had undergone orbital exenteration for sebaceous cell carcinoma. Prompted by the increasing use of topical treatments for intraepithelial disease, the authors were keen to discover the frequency of spread of tumour cells...

G-CSF intravitreal injections for NAION: a pilot study
In rodent models with anterior ischemic optic neuropathy (AION), granulocyte colony-stimulating factor (G-CSF) confers a neuroprotective effect on retinal ganglion cells (RGCs) via anti-apoptotic and anti-inflammatory processes. This prospective study investigated the efficacy of intravitreal injection of G-CSF for the...
