Artificial iris implantation in congenital aniridia: A systematic review.

Congenital aniridia is a rare, panocular disorder with a main phenotypic characteristic of a partial or complete absence of the iris existing alongside other ocular morbidities such as cataract, keratopathy, optic nerve and foveal hypoplasia, and nystagmus. The iris abnormality, however, often leads to symptoms such as photophobia, glare, and decreased visual acuity, as well as cosmetic dissatisfaction. Current management options for the iris deficit include colored iris contact lenses, corneal tattooing, and tinted contact lenses.

Coexistence of Meesmann Corneal Dystrophy and a Pseudo-Unilateral Lattice Corneal Dystrophy in a Patient With a Novel Pathogenic Variant in the Keratin K3 Gene: A Case Report.

Purpose: This study aims to clinically and genetically report a case of coexisting Meesmann corneal dystrophy (MECD) and pseudo-unilateral lattice corneal dystrophy (LCD).

Methods: Clinical characterization was supported by a complete ophthalmological evaluation, including visual acuity measurement and slit-lamp examination. Molecular diagnosis was performed by whole-exome sequencing analyzing the gelsolin, keratin K3 (KRT3), keratin K12, and transforming growth factor-beta-induced genes.

Comparison of United States and International Ophthalmic Drug Pricing.

Purpose: To compare United States and international drug pricing for commonly prescribed intravitreal and topical ophthalmic medications.

Design: Cross-sectional observational study.

Methods: For 25 commonly used ophthalmic medications (3 intravitreal, 22 topical), we obtained 2017 third quarter United States average wholesale price (AWP), drug acquisition cost, or consumer pricing through United States government health insurance plans (Veterans Affairs [VA], Medicaid, Medicare Part B, and Medicare Part D) and commercial drug plans (CVS Caremark and Navitus Health Solutions), online pricing without insurance through a large United States warehouse retailer (Costco), and international drug pricing through government-sponsored health plans in Italy, Spain, Turkey, Canada, and Japan.

Toxic corneal reaction due to exposure to palytoxin.

A case is presented of corneal toxicity after exposure to palytoxin. A 42 year-old man came with symptoms of pain and blurred vision in his right eye. He reported that a zoanthid coral from a saltwater aquarium had squirted into his eye.

Healing indicators after pterygium excision by optical coherence tomography.

Purpose: To establish the sequence of tomographic changes in the tissue recovery process after pterygium excision and to propose healing indicators.

Methods: Optical coherence tomography (OCT) images were taken at 1 week, 1, 3 and 6 months after lesion excision in 73 eyes of 73 patients (33 male, 40 female; mean age 50, S.D.
