Significance: There is a clinical necessity for dry eye disease treatments that perform across a broad range of presenting patient severities. Varenicline solution nasal spray (VNS), a unique cholinergic agonist ocular surface-sparing nasal spray therapy, demonstrated significant improvement in both signs and symptoms of dry eye disease in subjects with mild, moderate, and severe symptoms as the clinical studies enrolled a more real-world patient population.
Purpose: This study evaluated efficacy outcomes for VNS in patients with mild-moderate and severe dry eye disease.
Cataracts are a leading cause of preventable blindness globally. Although care varies between developing and industrialized countries, surgery is the single effective approach to treating cataracts. From the earliest documented primitive cataract removals to today's advanced techniques, cataract surgery has evolved dramatically.

View Article and Find Full Text PDFIontophoresis is a noninvasive delivery system designed to overcome barriers to ocular penetration of topical ophthalmic medications by employing a low-amplitude electrical current to promote the migration of a charged drug substance across biological membranes. Trans-scleral iontophoresis of dexamethasone phosphate has demonstrated dramatically increased intraocular concentrations of dexamethasone in rabbit ocular tissues compared with topical instillation, including 50- to 100-fold greater aqueous humor concentrations. This article reviews available data on recent clinical applications of iontophoretic ophthalmic drug delivery.

Design: Prospective, randomized, double-masked, parallel group, noninferiority clinical trial.
Methods: A total of 193 subjects with active noninfectious anterior uveitis (anterior chamber [AC] cell count ≥11 cells) were randomized to EGP-437 delivered by iontophoresis (days 0 and 7) or self-administered PA 1% daily (tapered schedule, days 0-28).
: Corneal collagen crosslinking (CXL) through an intact epithelium (epi-on) at high irradiance could potentially improve patient comfort, visual recovery, and clinical workflow compared to conventional epi-off CXL. However, intact epithelium limits stromal delivery of the oxygen, photosensitizer, and ultraviolet-A (UV-A) radiation needed to drive CXL. This study evaluated three different epi-on CXL protocols compared to positive and negative controls, specifically focusing on the impact of supplemental oxygen.

Design: Double-masked, randomized, multicenter, parallel-group, noninferiority clinical study.
Importance: Determining factors associated with endothelial cell loss after Descemet stripping automated endothelial keratoplasty (DSAEK) could improve long-term graft survival.
Objective: To evaluate the associations of donor, recipient, and operative factors with endothelial cell density (ECD) 3 years after DSAEK in the Cornea Preservation Time Study.
Design, Setting, And Participants: This cohort study was a secondary analysis of data collected in a multicenter, double-masked, randomized clinical trial.
Drugs across many pharmacologic classes induce corneal epithelial changes. Many of these drugs have cationic amphiphilic structures, with a hydrophobic ring and hydrophilic cationic amine side chain that allow them to cross cell membranes. These drugs lead to intracellular phospholipid accumulation, often manifested in the cornea by vortex keratopathy, with no effect on visual acuity and few ocular symptoms.

Excised redundant, forniceal "conjunctival" tissue from a 67-year-old man who experienced a chemical injury to his OS 25 years earlier was evaluated histopathologically with the hematoxylin-eosin, periodic acid Schiff (PAS) with and without diastase, mucicarmine, and Alcian blue methods. Additional immunoperoxidase testing for gross cystic disease fluid protein-15 (GCDFP-15) was undertaken. Non-keratinizing squamous epithelium composed of 8 to 10 layers of swollen keratinocytes without goblet cells surmounted a variably dense and well-vascularized collagenized lamina propria deep to which, in submucosal fibroadipose tissue, was embedded an accessory gland.

Purpose: To evaluate the effectiveness of a hydrogel sealant versus a suture in preventing fluid egress after wound leakage in cataract surgery.
Setting: Twenty-four ophthalmic clinical practices in the United States.
Design: Prospective randomized parallel-arm controlled multicenter subject-masked study.
Purpose: To develop and evaluate a calibrated force gauge designed to simulate the effect of patient-induced manipulation of the eye with resultant elevation of intraocular pressure (IOP) and use the device to determine the stability of cataract incisions.
Setting: Three private practice study sites.
Design: Clinical trials.
Purpose: The purpose of this study is to characterize the bacterial flora of the ocular and periocular surface in cataract surgery patients and to determine the prevalence of methicillin resistance among staphylococcal isolates obtained from health care workers (HCWs) and non-HCWs.
Methods: In this prospective, multicenter, case series study, eyelid and conjunctival cultures were obtained from the nonoperative eye of 399 consecutive cataract patients on the day of surgery prior to application of topical anesthetics, antibiotics, or antiseptics. Speciation and susceptibility testing were performed at the Dean A.
Purpose: To compare the safety and efficacy of a hydrogel bandage and a collagen corneal shield in providing wound protection and relief of pain/discomfort in the acute period after uneventful unilateral clear corneal phacoemulsification cataract surgery with foldable intraocular lens (IOL) implantation.
Setting: Seventeen investigational sites in the United States.
Design: Prospective randomized single-masked parallel study.
Purpose: To evaluate the efficacy and safety of twice-daily, preservative-free ketorolac 0.45% (Acuvail; Allergan, Inc, Irvine, California, USA) administration for treatment of inflammation and pain after cataract surgery.
Design: Prospective, randomized trial.
Objective: Acute conjunctivitis is an extremely common condition and can be associated with significant morbidity and economic burden. Despite this, considerable controversy exists pertaining to the prevalence, diagnosis, management, and treatment of the condition. A panel of ophthalmology experts was assembled to review and discuss the current evidence based literature as it pertains to each of these persistent controversies.

We report a case of exacerbation of undiagnosed ocular cicatricial pemphigoid after repair of involutional entropion. A lateral tarsal strip was performed to address entropion in the setting of eyelid laxity. No evidence of ocular cicatricial pemphigoid was observed before surgery.
View Article and Find Full Text PDFVernal conjunctivitis is a bilateral, seasonal, external ocular inflammatory disease of unknown cause. Afflicted patients experience intense itching, tearing, photophobia, and mucous discharge, and usually demonstrate large cobblestone papillae on their superior tarsal conjunctiva and limbal conjunctiva. It primarily affects children, may be related to atopy, and has environmental and racial predilections.
