OBJECTIVES: To describe the ophthoselfie, a method by which everyone can take detailed self-images of the cornea and anterior segment with a smartphone. MATERIALS AND METHODS: A 90-diopter non-contact double aspheric lens was attached to posterior camera of the smartphone by clear tape. Images of one eye on the screen of the smartphone could be seen with the other eye in the mirror and images were taken. RESULTS: Accurate and detailed images of the cornea and anterior segment of the eye could be taken...

PURPOSE: To determine the 1-year changes of mesopic higher order aberrations (HOAs) and contrast sensitivity (CS) after accelerated corneal cross linking (CXL) in progressive keratoconus. METHODS: In this prospective case series, 70 eyes of 62 keratoconic patients underwent accelerated CXL (18 mW/cm(2), 5 min). HOAs and CS were measured using the OPD Scan III and CSV-1000 CS test charts under mesopic conditions before and 6 and 12 months after CXL. RESULTS: At 1 year, logarithmic mesopic CS in spatial frequencies of 3, 6, 12, and 18 cycles per degree (CPD) had increased by 0...

m-miR-184 (mutant miR-184, r.57c > u) appears in familial hereditary ocular diseases, including keratoconus, cataracts, EDICT (endothelial dystrophy, iris hypoplasia, congenital cataract, and stromal thinning) syndrome, severe keratoconus, and non-ectatic corneal thinning. The biological function of m-miR-184 in these ocular diseases remains unclear. With the emergence of high-throughput sequencing, it is now possible to discover many different biological components simultaneously. Using two different RNA libraries, we sequenced the complete transcriptome of HLE cells treated with miR-184, m-miR-184, and a negative control...

PURPOSE: Common polymorphic variants upstream of Zinc finger protein gene 469 (ZNF469) have been associated with central corneal thickness. Rare ZNF469 variants have been shown in keratoconus patients. The aim of the current study was to investigate the frequency of ZNF 469 gene variants in rapidly progressive advance keratoconus patients who underwent corneal transplant surgery by the age of 30, compared to their frequency in the normal Turkish population. METHODS: A search in a patient database was performed to identify patients with a rapidly progressive keratoconus requiring corneal transplant surgery by the age of 30 in at least one eye...

PURPOSE: The aim was to assess the repeatability of Fourier transfom analysis of videokeratographic data using Pentacam in normal (CG), keratoconic (KC) and post-CXL (CXL) corneas. METHODS: This was a prospective, clinic-based, observational study. One randomly selected eye from all study participants was included in the analysis: 62 normal eyes (CG group), 33 keratoconus eyes (KC group), while 34 eyes, which had already received CXL treatment, formed the CXL group...

OBJECTIVES: To describe and compare corneal peripheral angles in normal and keratoconic eyes, to gain a better understanding of the topography of the periphery of the cornea in keratoconus and assist practitioners in the selection and fitting of large diameter contact lenses. METHODS: Eighty-eight eyes were included in the study, divided into three groups: healthy (A0, 28 eyes), keratoconus at stage I according to the Amsler-Krumeich classification (AI, 33 eyes) and keratoconus at stages II to IV (AII, 27 eyes)...

Ocular manifestations related to atopic dermatitis include keratoconus, keratoconjunctivitis, cataract, and retinal detachment. The authors report three cases of retinal detachment associated with atopic dermatitis. Although the pathogenesis is poorly understood, chronic blunt trauma may play a role in the development of retinal detachment. In addition, retinal detachments associated with atopic dermatitis may have lower rates of successful retinal detachment repair. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:513-517...

PURPOSE: To compare the actual depth of the tunnel created with femtosecond laser for intracorneal ring segment (ICRS) implantation with the target depth in keratoconus patients. METHODS: In this mix design study, eligible keratoconus patients were identified through chart review. The inclusion criterion was a history of ICRS implantation with femtosecond laser more than 6 months prior to enrollment. Participants underwent anterior segment optical coherence tomography using Spectralis (Heidelberg Engineering GmbH, Heidelberg, Germany) for depth measurement defined as the distance from the anterior corneal surface to anterior rim of the ring...

BACKGROUND: Ocular comorbidities are common in atopic dermatitis (AD) as the result of the disease itself or the use of medication. No large-scale epidemiologic data exist on the prevalence of ocular comorbidities in adults with AD. OBJECTIVES: We sought to examine the prevalence and risk of selected ocular comorbidities in adult patients with AD. METHODS: All Danish individuals ≥18 years of age were linked in nationwide registries. Adjusted hazard ratios (HRs) were estimated by means of Cox regression...

The management of severe keratoconus requires corneal transplantation, for which the gold standard is deep anterior lamellar keratoplasty (DALK), preserving the healthy Descemet's membrane and endothelium. The safety and reproducibility of corneal cuts have been improved by the evolution of femtosecond lasers in refractive surgery, and femtosecond laser in DALK would seem to provide the same advantages over the manual method. In our retrospective study, we compare functional and anatomical results of femtosecond-assisted DALK versus manual trephination DALK in patients with keratoconus in stage 4 of the Krumeich classification...

BACKGROUND AND AIMS: Many studies of corneal transplantation focus on graft failure or rejection as endpoints, or report visual outcomes at one postoperative time point. We aimed to study the stability of visual outcomes between 2 and 5 years following corneal transplantation. METHODS: All patients with keratoconus (868) or Fuchs endothelial dystrophy (FED) (569) receiving their first corneal transplant for visual purposes in the UK between January 2003 and December 2009 were included...

PURPOSE: To investigate the effect of the severity of keratoconus on the corneal endothelium using specular microscopy. METHODS: Seven hundred and twelve eyes from the Homburg Keratoconus Center (HKC) database were included in this retrospective study. Corneal endothelium was evaluated using the Tomey EM-3000 specular microscope. Keratoconus-related topographic and tomographic data were obtained from Scheimpflug-based tomography (Oculus Pentacam(®) HR). Eyes were classified into stages 0 (healthy) to 4 (severe keratoconus) according to the Topographic Keratoconus Classification (TKC)...

PURPOSE OF REVIEW: To identify and evaluate the risk factors of iatrogenic ectasia after refractive surgery. RECENT FINDINGS: We reviewed recently published papers that identified various risk factors associated with ectasia after LASIK, photorefractive keratectomy, small incision lenticule extraction, and other refractive surgical procedures. We also attempted to evaluate the relative contributions of these factors to the development of ectasia following refractive surgery...

BACKGROUND: To report a surgical method for treating corneal oedema in a case of late-onset Descemet membrane detachment after penetrating keratoplasty. CASE PRESENTATION: A 55-year old patient presented with sudden visual loss in his left eye 28 years after penetrating keratoplasty for keratoconus. Slit-lamp biomicroscopy revealed a distortion of the corneal graft anatomy with protrusion of the graft and peripheral thinning and steepening in the residual host tissue, accompanied by corneal graft oedema...

Purpose: We aimed to report and analyze topographic and refractive outcomes following corneal collagen crosslinking (CXL) in patients with progressive keratoconus (KC). Methods: We performed a retrospective, analytical, and observational study of 100 eyes from 74 progressive KC patients who underwent CXL at the Eye Hospital of Paraná. Keratometric values were analyzed preoperatively as well as 3 and 12 months postoperatively. Results: For a total of 100 eyes, 68 belonged to male patients...
