PURPOSE: Lichen planopilaris (LPP) is a chronic lymphocytic- mediated disorder that selectively involves hair follicles, leading to cicatricial alopecia. The eyelash follicle and meibomian gland (MG) might also be involved in the disease process leading to ocular surface problems. METHODS: In this Cross-sectional case -control study, twenty-three patients with histologically confirmed LPP and 23 healthy controls were recruited in this controlled study. To quantify the signs and symptoms of LPP, we used the Lichen Planopilaris Activity Index...

PURPOSE: To evaluate Descemet membrane endothelial keratoplasty (DMEK) in the setting of failed penetrating keratoplasty (PKP) and to identify factors associated with DMEK success and failure after PKP. METHODS: A retrospective chart review of patients who underwent DMEK for failed PKP at Toronto Western Hospital, Canada, between 2014 and 2017 was performed. Demographic characteristics, number of previous transplants, intraoperative and postoperative complications, best spectacle-corrected visual acuity (BSCVA), and endothelial cell density were analyzed...

PURPOSE: To compare whole eye enucleation and corneoscleral disc (CD) excision as donor cornea harvesting techniques for possible effects on corneal cultivation and the clinical outcome of the corneal grafts after transplantation in 2929 cases. METHODS: A retrospective analysis was performed on the Hamburg Eye Bank database using comparative statistics. The standard method for donor cornea recovery at the Hamburg Eye Bank changed from enucleation of the whole eye to CD in situ excision in 2008...

PURPOSE: To determine whether metformin use and diabetes mellitus (DM) affect central corneal endothelial cell density (ECD) by examining an eye bank corneal donor database. METHODS: The Lions Eye Institute corneal donor database, which consists of 38,318 corneal samples, was examined. Associations of ECD with metformin use and DM were tested by mixed effects linear models that account for correlations of outcomes between eyes within subjects adjusting for age, intraocular lens status, and glaucoma...

PURPOSE: To evaluate the long-term results of corneal collagen cross-linking (CXL) for treatment of pediatric keratoconus and the long-term outcomes of the fellow untreated keratoconic eye in patients younger than 18 years old. METHODS: A retrospective case analysis was performed on 88 eyes of 44 patients aged 18 years or younger, with keratoconus, who underwent CXL in at least 1 eye. Follow-up measurements, for the treated and untreated eye pair, taken up to 5 years after treatment, were compared with baseline values...

PURPOSE: To identify mycotoxin genes among clinical ocular isolates of Fusarium species and to correlate these with clinical outcomes of Fusarium keratitis. METHODS: Fifty-four clinical isolates of Fusarium were retrieved from the Bascom Palmer Eye Institute Ocular Microbiology Laboratory data bank. Multiplex polymerase chain reactions were run to confirm the identification of Fusarium species [internal transcribed spacer sequence, translation elongation factor 1-α (TEF) and β-tubulin] and to detect the presence of genes encoding production of fumonisin B mycotoxins (FUM1 and FUM8) and trichothecene mycotoxins (deoxynivalenol and nivalenol)...

PURPOSE: To evaluate the effectiveness of corneal collagen cross-linking with Dresden and accelerated protocols to treat keratoconus by Scheimpflug tomography. METHODS: Fifty-eight eyes with manifest keratoconus were measured preoperatively at least twice with the Pentacam. The difference of relevant variables for keratoconus progression (eg, D value, thinnest pachymetry, Kmax) was established. After evident progression, patients underwent corneal cross-linking (29 eyes with the Dresden protocol and 29 eyes with the accelerated protocol)...

PURPOSE: To evaluate the effect of corneal vesicles in patients with posterior corneal vesicles (PCV) on corneal endothelial cell (CEC) density and the acquisition of amblyopia. METHODS: In this retrospective study of patients with PCV (18 eyes of 14 patients), CEC density was examined by noncontact specular microscopy during each follow-up examination. Best-corrected visual acuity and the objective refractive error were also examined. RESULTS: Of the 14 total patients, 10 were diagnosed with PCV and 4 were diagnosed with bilateral suspected PCV or posterior polymorphous corneal dystrophy (PPCD), and in all patients, no ocular abnormality other than corneal vesicles was observed...

PURPOSE: To evaluate the long-term changes in anterior and posterior corneal irregular astigmatism and curvatures after small incision lenticule extraction (SMILE). METHODS: Fifty eyes of 28 patients underwent SMILE for myopic astigmatism. All procedures were performed using the VisuMax® femtosecond laser. A Scheimpflug camera was used for preoperative and 3-year postoperative tomography. Anterior and posterior corneal Fourier parameters (spherical component, regular astigmatism, asymmetry, and irregularity) and curvature data were evaluated and compared within 2 subgroups according to the magnitude of the refractive correction (low myopia group: spherical equivalent (SEQ) ≥ -6 D; high myopia group: (SEQ) < -6 D)...

PURPOSE: To evaluate the clinical outcomes of thermal pulsation treatment in patients with meibomian gland dysfunction (MGD) and dry eye secondary to Sjogren disease. METHODS: Twenty-four eyes from 13 patients with previously diagnosed Sjogren disease who presented to our institution with dry eye symptoms and had thermal pulsation treatment were prospectively followed up. Patients underwent comprehensive slit-lamp examination, including MGD grading, gland oil flow, corneal and conjunctival staining scores, and tear break-up time (TBUT)...

PURPOSE: To report the identification of the collagen, type XVII, alpha 1 (COL17A1) c.3156C>T mutation associated with epithelial recurrent erosion dystrophy (ERED) in a Thai family. METHODS: Slit-lamp examination was performed to determine the affected status of each member of a Thai family, with multiple members demonstrating scattered Bowman layer opacities. After genomic deoxyribonucleic acid (DNA) was isolated from saliva, polymerase chain reaction (PCR) amplification and Sanger sequencing were performed to screen COL17A1 and exons 4 and 12 of the transforming growth factor β-induced gene...
