P Výborný, S Sičáková, Z Flórová, I Sováková
During the period of the last six years (2010-2016), the authors performed Selective Laser Trabeculoplasty (SLT) in 32 women (64 eyes); pregnant women patients with primary open angle glaucoma were referred to the Department of Ophthalmology, First Medical Faculty, Charles University, and Central Military Hospital in Prague, Czech Republic, European Union, to perform this procedure with the goal to interrupt their antiglaucomatic treatment by means of eye drops during the pregnancy and the breastfeeding period...

Sickle cell retinopathy (SCR) is the most representative ophthalmologic complication of sickle cell disease (SCD), a hemoglobinopathy affecting both adults and children. SCR presents a wide spectrum of manifestations and may even lead to irreversible vision loss if not properly diagnosed and treated at the earliest. Over the past decade, multidisciplinary research developments have focused upon systemic, genetic, and ocular risk factors of SCR, enabling the clinician to better diagnose and manage these patients...

A 27-year-old woman had microkeratome-assisted laser in situ keratomileusis (LASIK) for moderate bilateral hyperopia. The preoperative ophthalmologic examination was unremarkable except for minimal lissamine green staining bilaterally on the nasal conjunctiva. On the first postoperative day, the uncorrected distance visual acuity (UDVA) was 20/20 bilaterally and the corneas were clear. Four days later, the patient presented with mild blur in both eyes. Examination showed diffuse bilateral epithelial cysts encompassing the central 6...

Epiphora is one of the most common symptoms for clinical ophthalmological consultation. This symptom is mostly caused by stenosis of the lacrimal drainage system. Over a century, external dacryocystostomy according to Toti was the treatment of choice. Today, new very encouraging minimally invasive techniques for recanalisation of the lacrimal drainage system, such as microdrilldacryoplasty or laserdacryoplasty, as well as bypass-based techniques, such as transcanalicular laser-assisted dacryocystorhinostomy, become more important in the treatment of dacryostenosis...

OBJECTIVES: To assess healthcare resource use and costs of treating people with clinically significant diabetic macular edema (DME) with fluocinolone acetonide (FAc) 190 µg intravitreal implant in routine clinical practice. METHODS: The retrospective Iluvien Clinical Evidence (ICE-UK) study collected data on people prescribed the FAc implant in any one of 13 ophthalmology centers between April 1, 2013 and April 15, 2015. Data were collected for 12 months before and after implantation...

Peripheral retinal laser ablation for high-risk retinopathy of prematurity (ROP) improves visual outcomes. Some pediatric ophthalmology fellows receive little exposure to this procedure. The authors identified and evaluated an animal teaching model that simulates peripheral retinal laser ablation in human infants with ROP. [J Pediatr Ophthalmol Strabismus. 2017;54:e47-e49.].

REVIEW
M Blum, W Sekundo
Refractive lenticule extraction (ReLEx/SMILE) is a refractive surgical method developed by the authors in stages primarily for correction of myopia and myopic astigmatism, in which a femtosecond laser is exclusively used. In the (ReLEx/SMILE) method a refractive lenticule is generated by the femtosecond laser, which is subsequently extracted through a small incision. Opening of the corneal surface with a flap and use of an excimer laser is no longer necessary. In 2013 the method was newly assessed and classified by the Joint Commisssion for Refractive Surgery (KRC) of the Professional Association of Ophthalmologists (BVA) and the German Ophthalmological Society (DOG)...

Importance: Vitreous floaters are common and can worsen visual quality. YAG vitreolysis is an untested treatment for floaters. Objective: To evaluate YAG laser vitreolysis vs sham vitreolysis for symptomatic Weiss ring floaters from posterior vitreous detachment. Design, Setting, and Participants: This single-center, masked, sham-controlled randomized clinical trial was performed from March 25, 2015, to August 3, 2016, in 52 eyes of 52 patients (36 cases and 16 controls) treated at a private ophthalmology practice...

We repeatedly examined 17 subjects with presumed bilateral physiological excavation labeled as pathological and/or borderline via HRT to verify the diagnosis of physiological cupping or to monitor the long-term progression into normal tension glaucoma. Patients and Methods 17 Subjects with presumed bilateral physiological cupping and large optic discs were included in this long-term follow-up study. All subjects underwent regular detailed ophthalmologic examinations, including intraocular pressure measurement via Goldmann applanation tonometry (GAT), retinal nerve fiber layer imaging via optical coherence tonometry (OCT) and visual field testing and optic disc imaging using the HRT...

PURPOSE: To describe a case of acute angle-closure glaucoma secondary to intermittent mydriasis related to Pourfour du Petit Syndrome caused by tracheal deviation. MATERIALS AND METHODS: A 70-year-old Caucasian woman visited the Emergency Room of the University Eye Clinic complaining of blurring of vision and difficulty to move superior eyelid in her right eye. Examination revealed reactive mydriasis, and upper lid retraction on the right side. The rest of the ophthalmological examination was normal, and a cranial computed tomography (CT) did not identify any abnormalities...

During microsurgery, en face imaging of the surgical field through the operating microscope limits the surgeon's depth perception and visualization of instruments and sub-surface anatomy. Surgical procedures outside microsurgery, such as breast tumor resections, may also benefit from visualization of the sub-surface tissue structures. The widespread clinical adoption of optical coherence tomography (OCT) in ophthalmology and its growing prominence in other fields, such as cancer imaging, has motivated the development of intraoperative OCT for real-time tomographic visualization of surgical interventions...

BACKGROUND: Residency training is the basis of good clinical and surgical practice. PURPOSE: The aim is to know the demographics, training experience, and perception of young ophthalmologists to improve the present residency programs in India. SETTING: Young ophthalmologists trained in India. METHODS: A survey was conducted by the Academic and Research Committee of the All India Ophthalmology Society, in 2014-2016 of young ophthalmologists (those trained between 2002 and 2012, with 2-10 years' postresidency experience) to gauge teaching of clinical and surgical skills during the postgraduate residency program...

We report retinal functional and structural changes of a 40-year-old man diagnosed with occult macular dystrophy. Comprehensive ophthalmological evaluation was performed, followed by spectral-domain optical coherence tomography (SD-OC - Heidelberg) and image acquisition using an adaptive optics (AO) camera (RTX1, Imagine Eyes) for photoreceptor density analysis. Functional tests included full-field ERG (ERG) and multifocal electroretinography (mfERG) (Diagnosys, LLC) and microperimetry with scanning laser ophthalmoscope (SLO) fixation controlled (MAIA, CenterVUE)...

Glaucoma is a heterogeneous group of diseases characterised by cupping of the optic nerve head and visual-field damage. It is the most frequent cause of irreversible blindness worldwide. Progression usually stops if the intraocular pressure is lowered by 30-50% from baseline. Its worldwide age-standardised prevalence in the population aged 40 years or older is about 3·5%. Chronic forms of glaucoma are painless and symptomatic visual-field defects occur late. Early detection by ophthalmological examination is mandatory...
