Grey Filter Contact Lens as Therapeutic Option for Acquired Reduced Binocular Visual Performance.

Unlabelled: Disturbing binocular problems can be too complex to be treated in such a way that comfortable binocular single vision is restored. The grey filter contact lens could offer a safe and clinically useful way to help these patients.

Background: In unilateral acquired reduced visual performance or intractable diplopia the binocular performance often is less than the performance of the better eye, possibly leading to complaints of binocular visual functioning.

Autosomal Recessive NRL Mutations in Patients with Enhanced S-Cone Syndrome.

Enhanced S-cone syndrome (ESCS) is mainly associated with mutations in the gene. However, rare mutations in the gene have been reported in patients with ESCS. We report on an ESCS phenotype in additional patients with autosomal recessive (ar) mutations.

A Rare Form of Retinal Dystrophy Caused by Hypomorphic Nonsense Mutations in CEP290.

Purpose: To identify the gene defect and to study the clinical characteristics and natural course of disease in a family originally diagnosed with oligocone trichromacy (OT), a rare congenital cone dysfunction syndrome.

Methods: Extensive clinical and ophthalmologic assessment was performed on two siblings with OT and long-term follow up data were analyzed. Subsequently, whole exome sequencing (WES) and Sanger sequence analysis of was performed in the two siblings.

[Functional vision disorder: timely examination pays off].

Patients with functional vision disorder (FVD) may present with poor visual acuity, visual field loss, or a combination of the two. This paper illustrates the utility of objective tests in diagnosing FVD. We use sweep visual evoked potentials and eye tracking as objective tests for visual acuity and visual field, respectively.
