PURPOSE: The aim of this study was to evaluate the effect of intravitreal injection of aflibercept (IVA) on blood coagulation tests in neovascular age-related macular degeneration (AMD) patients. METHODS: Thirty-four patients with neovascular AMD (study group) and 32 healthy individuals (control group) were enrolled. Prothrombin time (PT) and activated partial thromboplastin time (aPTT) were measured at different times in patients with neovascular AMD. RESULTS: The levels of PT and aPTT after IVA were decreased at 1 month after the first injection and 1 month after the second injection compared to the baseline measurement in the study group...

Congenital ectropion uveae (CEU) is a rare anomaly characterized by ectropion uveae, iris hypoplasia, iridotrabecular dysgenesis and glaucoma. The apparent ectropion uveae results from the spread of iris pigment epithelium beyond the iris ruff and onto the anterior surface of the iris. Conclusion Open-angle glaucoma results due to angle dysgenesis, so patients should be carefully examined periodically for its early detection.

PURPOSE: To evaluate changes in macular thickness, ganglion cell layer/inner plexiform layer (GCL/IPL) thickness, and retinal nerve fiber layer (RNFL) thickness in normal eyes and glaucomatous eyes using spectral domain optical coherence tomography (SD-OCT). METHODS: We enrolled 89 eyes (all left eyes), including 45 (of 45 patients) eyes with glaucoma and 44 (of 44 patients) normal eyes. The data from macular measurements using spectral domain optical coherence tomography were analyzed according to groups divided by age and glaucoma status...

BACKGROUND: To compare the consistency between the average scores of the contact central corneal thickness measurements from ultrasound pachymetry devices still gold standard, such as iPac(®) and Echoscan US-500, and noncontact measurements via Pentacam HR and Sirius topography. METHODS: This prospective study, subsequently admitted to the ophthalmology department, 76 healthy individuals were performed. The measurements were repeated three times for each eye, and average scores were statistically analyzed on the same day and almost at the same time...

BACKGROUND: To report a case series of early postoperative complications following combined accelerated corneal crosslinking (CXL) and trans-epithelial technique in keratoconus. CASE PRESENTATIONS: Eleven eyes underwent accelerated trans-epithelial CXL (18 mW/cm(2) for 5 min). Seven eyes (64%) developed complications in the first week postoperatively. Five eyes had large epithelial defects, and two eyes were complicated with diffuse punctate epithelial erosions...

PURPOSE: To improve the interventions provided for patients presenting with acute ophthalmic conditions to the ophthalmic emergency unit through applying the best available evidences from quality literature for managing such conditions. METHODS: A retrospective cohort study at a tertiary eye care university hospital in Riyadh, Saudi Arabia, involving a two-phase audit of diagnosis-intervention was conducted. The first phase was done retrospectively for the duration from April 1 to May 30, 2014, after disseminating the results of the first phase to King Abdulaziz University Hospital ophthalmology department staff, and the second phase was done retrospectively for the duration from November 1 to December 30, 2015...

PURPOSE: Iridocorneal endothelial (ICE) syndrome is a rare condition, and unique characteristics in Chinese patients can make diagnosis difficult. Our purpose was to describe the clinical characteristics and variations of ICE syndrome in 58 consecutive Chinese patients. METHODS: The clinical data of consecutive patients with ICE syndrome who were seen between 2008 and 2011 at the glaucoma clinic of our ophthalmology department were retrospectively reviewed. The diagnostic criteria for ICE syndrome were a "hammered-silver" appearance of the corneal endothelium and specular microscopy showing ICE cells characterized by the absence of a hexagonal appearance, dark areas within the cells, and a light-dark reversal pattern...

PURPOSE: Sarcoidosis is a major cause of granulomatous uveitis but rarely manifests as multiple choroidal granulomas. This report describes the use of enhanced depth imaging optical coherence tomography (EDI-OCT) to visualize changes occurring in multiple choroidal granulomas during treatment. METHODS: The patient was a 36-year-old Japanese man with histopathologically confirmed sarcoidosis, who was examined using EDI-OCT and showed multiple yellowish-white subretinal lesions in the peripapillary region and the arcade of the right eye...

PURPOSE: To compare the outcome of 23-gauge as compared with 25-gauge transconjunctival sutureless vitrectomy (TSV) in the management of dislocated intraocular lenses (IOLs). DESIGN: Retrospective, non-consecutive, comparative, interventional case series. PARTICIPANTS: Patients with dislocated intraocular lens who underwent sutureless PPV using either 23-gauge or 25-gauge instruments. METHODS: The patients who presented with a dislocated IOL, underwent TSV with repositioning of the intraocular lens, either in the sulcus or scleral-fixated sutured/glued...

PURPOSE: The aim of this study was to evaluate the aqueous outflow system through channelography with fluorescein during non-penetrating glaucoma surgery (canaloplasty or phacocanaloplasty) and find correlations with preoperative and postoperative intraocular pressure (IOP). METHODS: Thirty-six patients (40 eyes) who had channelography while undergoing non-penetrating glaucoma surgery were included in this prospective study. Several parameters assessed during the channelography included: diffuse and superficial scleral staining, the number of visible superficial connections to collectors, trabecular permeability and number of micro-ruptures of the trabecular meshwork...

PURPOSE: To investigate the dry eye after small incision lenticule extraction (SMILE) and explore the correlations between changes in the tear film stability, the tear secretion and the corneal surface regularity. METHODS: Sixty-two eyes of 22 men and 13 women who underwent SMILE were included in this study. Corneal topography was measured to assess the index of surface variance (ISV) and the index of vertical asymmetry (IVA). Dry eye tests including subjective symptom questionnaire, tear breakup time (TBUT), corneal fluorescein staining and Schirmer's test (ST) were evaluated before and at 1 and 6 months postoperatively...
