Nora W Muakkassa, Eric J Schwaber, Nora Laver, Jay S Duker
The authors report a case of a 57-year-old male with high myopia, extensive bilateral myelination of the retinal nerve fiber layer, bilateral vitreous cysts, and a solitary vasoproliferative tumor in the right eye. He underwent pars plana vitrectomy and multiple transpupillary thermotherapy treatments for recurrent vitreous hemorrhages and subretinal exudation from the vasoproliferative tumor. To the authors' knowledge, this is the first description of this constellation of findings and suggests this represents a new syndrome...

A A Shpak
To characterize a complex of disorders developing in patients with extreme values of anteroposterior axis of the eye, it is necessary to create an appropriate nomenclature. As a topic for discussion, authors suggest to supplement the existing classifications of myopia and hyperopia with 'character of ametropia' section (axial, refractive, mixed) and the definition of ametropias of very high (ultra-high/extreme) degree (a criterion for myopia is: <-10 D). In prospect, classification of such ametropias should be based on the length of the anteroposterior axis of the eye...

The article reviews development mechanisms of different refractive errors accompanied by marked defocus of light rays reaching the retina. Terminology used for such ametropias includes terms extreme, ultra-high and complicated. Justification of their usage for primary ametropias, whose symptom complex is based on changes in axial eye length, is an ongoing discussion. To comply with thesaurus definitions of 'diagnosis' and 'pathogenesis', to characterize refractive and anatomical-functional disorders in patients with primary ametropias it is proposed to use the terms 'hyperaxial and hypoaxial syndromes' with elaboration of specific symptoms instead of such expressions as extreme (ultra-high) myopia and hypermetropia...

Central corneal thickness (CCT) is a highly heritable trait associated with complex eye diseases such as keratoconus and glaucoma. We perform a genome-wide association meta-analysis of CCT and identify 19 novel regions. In addition to adding support for known connective tissue-related pathways, pathway analyses uncover previously unreported gene sets. Remarkably, >20% of the CCT-loci are near or within Mendelian disorder genes. These included FBN1, ADAMTS2 and TGFB2 which associate with connective tissue disorders (Marfan, Ehlers-Danlos and Loeys-Dietz syndromes), and the LUM-DCN-KERA gene complex involved in myopia, corneal dystrophies and cornea plana...

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 describe a foveomacular retinoschisis that has not been described. METHODS: Patients with foveomacular retinoschisis were included. Exclusion criteria included refractive error over -6.00 diopters, presence of posterior staphyloma, positive RS1-gene mutation, family history of retinoschisis, optic disk abnormalities, or glaucoma. Vitrectomy was performed on eyes with functional or structural deterioration. RESULTS: Seventeen eyes from 10 patients (15-30 years old, 8 females and 2 males) with foveoschisis were recruited, with bilateral involvement in 7 patients and unilateral in 3 patients...

The incidence of high myopia is increasing worldwide with myopic maculopathy, a complication of myopia, often progressing to blindness. Our two-stage genome-wide association study of myopic maculopathy identifies a susceptibility locus at rs11873439 in an intron of CCDC102B (P = 1.77 × 10-12 and Pcorr  = 1.61 × 10-10 ). In contrast, this SNP is not significantly associated with myopia itself. The association between rs11873439 and myopic maculopathy is further confirmed in 2317 highly myopic patients (P = 2...

BACKGROUND: Femtosecond laser-assisted in situ keratomileusis (FS-LASIK) has gained widespread popularity as a safe, effective and predictable treatment for correcting myopia and myopic astigmatism.However, complications such as biomechanical changes, structural weakness, dry eye and induction of high-order aberrations (HOAs) have been associated with FS laser excision. The induction of HOAs has been reported to reduce quality of vision, leading to increased glare, halos, starburst and deterioration of contrast function corneal HOAs play a significant role in whole-eye aberration...

Myopia is a global public health issue with a worldwide prevalence of ∼30% and is estimated to rise to 50% by 2050. In addition to the burden associated with routine management of the condition, high myopia predisposes the eye to sight-threatening complications such as myopic maculopathy and glaucoma in adult life. Controlling onset and progression of myopia at a young age can reduce the risk of morbidity associated with high myopia. Progression of myopia can be slowed with various optical, environmental, and pharmaceutical strategies, of which atropine has proven to be the most effective...

Purpose: To compare refractive and biometric outcomes in patients with type 1 retinopathy of prematurity (ROP) treated with intravitreal injection of ranibizumab (IVR) versus bevacizumab (IVB), at a corrected age of 3 years. Methods: A retrospective case series compared cycloplegic refractive statuses and biometric statuses in patients who received either IVR or IVB for type 1 ROP, from April 2011 to April 2014. Results: A total of 62 eyes (33 patients) with type 1 ROP were evaluated (26 eyes in 13 IVR patients and 36 eyes in 20 IVB patients)...
