In this report, a case of ocular scleral metastasis was reported in a patient with a past history of esophageal squamous cell carcinoma. The patient was a 58-year-old male who was admitted to Urmia Imam Khomeini Hospital, Urmia, Iran, 8 years ago with progressive dysphasia. Seven years after initial diagnosis and treatment of esophageal cancer, the patient had no signs or symptoms of the disease. But 2 months ago, he was referred to the hospital due to ocular swelling, redness and watering. Pathologic examination of the excised lesion at Farabi Hospital reported metastasis of squamous cell carcinoma to the connective tissue of the sclera...

BACKGROUND: Intracorneal ring segment implantation is an effective and safe method of visual improvement in patients with keratoconus. The aim of our study was to evaluate the long-term clinical outcomes after Keraring implantation for keratoconus in patients older than 40 years. METHODS: Eleven eyes from 11 patients with keratoconus who underwent femtosecond laser-assisted Keraring implantation for keratoconus were included in this retrospective study. The uncorrected visual acuity (UCVA), corrected visual acuity, keratometric readings, central corneal thickness and thinnest corneal pachymetry were evaluated preoperatively and 6 months after the Keraring implantation...

INTRODUCTION: Many authors have reported on a myopic post-operative refractive prediction error when combining phacoemulsification with pars plana vitrectomy (phacovitrectomy). In this study we evaluate the amount of this error in our facility and try to elucidate the various factors involved. METHODS: This was a retrospective study which included 140 patients who underwent phacovitrectomy (39 with macular holes, 88 with puckers, and 13 with floaters). Post-operative refractive error was defined as the difference between the actual spherical equivalent (SEQ) and expected SEQ based on the SRK/T and Holladay-II formulas...

INTRODUCTION: Corneal thinning disorders caused by keratoconus often lead to protrusion, irregular astigmatism, and even perforation. Keratoconus, like other corneal ectasia, does not have a known cause. Severe cases of keratoconus may require correction or restoration of tectonic integrity of the cornea by surgical means. Intracorneal ring segments are a new modality in the treatment of corneal ectactic disorders. A new technique of stopping the evolution of keratoconus and strengthening the cornea is combining techniques of intrastromal corneal ring implantation and corneal collagen cross-linking...

The many internal and external factors that contribute to the pathophysiology of dry eye disease (DED) create a difficult milieu for its study and complicate its clinical diagnosis and treatment. The controlled adverse environment (CAE(®)) model has been developed to minimize the variability that arises from exogenous factors and to exacerbate the signs and symptoms of DED by stressing the ocular surface in a safe, standardized, controlled, and reproducible manner. By integrating sensitive, specific, and clinically relevant endpoints, the CAE has proven to be a unique and adaptable model for both identifying study-specific patient populations with modifiable signs and symptoms, and for tailoring the evaluation of interventions in clinical research studies...

Gennady Landa, Khoa Pham
INTRODUCTION: Primary posterior capsular plaques can be highly adherent to the posterior capsule leading to possible posterior capsular rupture during attempted removal. Here we describe a novel method for posterior capsular plaque removal using a technique inspired by the experience of retina surgeon in the peeling of membranes from the posterior pole. METHODS: Retinal end-grasping forceps were used to peel the plaque from the posterior capsule. RESULTS: We have performed this technique on 12 eyes with successful removal of the posterior capsular plaque in all instances without compromise of the posterior capsule in any case...

INTRODUCTION: This report describes the first known case of late-onset intrusion of an intrastromal ring segment into the anterior chamber due to posterior migration of a ring segment. To our knowledge, intrastromal ring segment penetration has only been shown to occur in the intraoperative or immediate postoperative period. We postulate that the perforation in this case is due to progressive thinning of the cornea, possibly in combination with habitual eye rubbing. CASE REPORT: A 44-year-old man presented with acute corneal hydrops related to penetration of Descemet's membrane and endothelium by an intrastromal ring segment implanted 7 years prior...

INTRODUCTION: Bromfenac is a well-known topical ophthalmic nonsteroidal anti-inflammatory drug (NSAID) that is commercialized in the USA and other regions of the world. A new formulation, 0.075% bromfenac in DuraSite®, was developed to treat postoperative inflammation and reduce pain in patients who have undergone cataract surgery. We hypothesized that efficacy and safety would be enhanced with twice-daily (BID) dosing compared to once-daily (QD) dosing. METHODS: This was a multicenter, double-masked, comparative study in which 40 and 45 subjects were randomized to groups receiving BID dosing and QD dosing, respectively...

REVIEW
Ejaz Ansari
For several years, the gold standard for surgical treatment of glaucoma has been trabeculectomy. Although very successful at reducing intraocular pressure (IOP), there are several potential complications of trabeculectomy, including sight-threatening ones. This has stimulated much research aimed at the development of new and effective procedures to lower IOP with an enhanced safety profile. Minimally invasive glaucoma surgery (MIGS) procedures prioritise patient safety but also demonstrate efficacy in reducing IOP...
