Purpose: To evaluate the efficacy of vitrectomy with epiretinal proliferation (EP) sparing for full-thickness macular hole (FTMH) accompanied by EP.

Methods: A multicenter, retrospective study. Eyes were divided into two groups: the sparing group (Group S) included eyes in which the EP around the hole was peeled and preserved, whereas the removal group (Group R) included eyes in which the EP was partially or completely removed.

Measurement of paracentral stereopsis using a new method with the binocular open perimeter imovifa in normal adults.

Purpose: No method to quantitatively evaluate stereopsis within the 15º visual field has been clinically established. We developed a program to measure paracentral stereopsis and evaluated its feasibility in visually normal participants.

Study Design: Experimental investigation METHODS: Ten visually normal volunteers with stereopsis of 60 arcseconds or better were included.

Clinical course of two siblings with potassium voltage-gated channel modifier subfamily V member 2 (KCNV2)-associated retinopathy.

Background: KCNV2-associated retinopathy causes a phenotype reported as "cone dystrophy with nyctalopia and supernormal rod responses (CDSRR; OMIM# 610356)," featuring pathognomonic findings on electroretinography (ERG). Here, we report the clinical courses of two siblings with CDSRR.

Case Reports: Patient 1: A 3-year-old boy with intermittent exophoria was referred to our hospital.

Substance P promotes transforming growth factor-β-induced collagen synthesis in human corneal fibroblasts.

Corneal fibroblasts maintain homeostasis of the corneal stroma by mediating the synthesis and degradation of extracellular collagen, and these actions are promoted by transforming growth factor-β (TGF-β) and interleukin-1β (IL-1β), respectively. The cornea is densely innervated with sensory nerve fibers that are not only responsible for sensation but also required for physiological processes such as tear secretion and wound healing. Loss or dysfunction of corneal nerves thus impairs corneal epithelial wound healing and can lead to neurotrophic keratopathy.

Disease-specific variant interpretation highlighted the genetic findings in 2325 Japanese patients with retinitis pigmentosa and allied diseases.

Background: As gene-specific therapy for inherited retinal dystrophy (IRD) advances, unified variant interpretation across institutes is becoming increasingly important. This study aims to update the genetic findings of 86 retinitis pigmentosa (RP)-related genes in a large number of Japanese patients with RP by applying the standardised variant interpretation guidelines for Japanese patients with IRD (J-IRD-VI guidelines) built upon the American College of Medical Genetics and Genomics and the Association for Molecular Pathology rules, and assess the contribution of these genes in RP-allied diseases.

Methods: We assessed 2325 probands with RP (n=2155, including n=1204 sequenced previously with the same sequencing panel) and allied diseases (n=170, newly analysed), including Usher syndrome, Leber congenital amaurosis and cone-rod dystrophy (CRD).

Sweeping technique for the removal of emulsified silicone oil droplets from the anterior surface of the iris using an ophthalmic absorption sponge.

Purpose: Silicone oil (SO) tamponade is frequently used in complex vitreoretinal surgeries, and SO migration into the anterior chamber can lead to complications such as glaucoma and corneal decompensation. A new technique is described for the efficient removal of emulsified SO droplets, which can adhere strongly to the anterior surface of the iris.

Methods: The tip of an ophthalmic absorption sponge was cut to an approximately 1x1 mm size.

Optical coherence tomography findings of the peripheral retina in patients with congenital X-linked retinoschisis.

Introduction: Congenital X-linked retinoschisis (XLRS) presents as macular retinoschisis/degeneration in almost all patients and as peripheral retinoschisis in half the patients. Although the optical coherence tomography (OCT) findings of macular retinoschisis have been well investigated, those of peripheral retinoschisis have rarely been reported. This study aimed to report the ultra-widefield OCT findings of the peripheral retina in patients with XLRS.

Factors affecting the total occlusion time in eyes with hyperopic anisometropic amblyopia.

Background: Amblyopia treatment by occluding the healthy eye is known to be effective during a sensitive critical period. This study aims to clarify the factors for the total occlusion time (TOT) required for the amblyopic eye to achieve a normal visual acuity (VA) level of 1.0 (0.

Development of a joint set of database parameters for the EU-ROP and Fight Childhood Blindness! ROP Registries.

Background/aims: The incidence of retinopathy of prematurity (ROP) is increasing and treatment options are expanding, often without accompanying safety data. We aimed to define a minimal, patient-centred data set that is feasible to collect in clinical practice and can be used collaboratively to track and compare outcomes of ROP treatment with a view to improving patient outcomes.

Methods: A multinational group of clinicians and a patient representative with expertise in ROP and registry development collaborated to develop a data set that focused on real-world parameters and outcomes that were patient centred, minimal and feasible to collect in routine clinical practice.

A new static visual field test algorithm: the Ambient Interactive ZEST (AIZE).

Visual field (VF) test is one of the most vital tests in the diagnosis of glaucoma and to monitor the disease worsening. In the past couple of decades, the standard automated perimetry (SAP) test takes a major role in VF test for glaucoma patients. The SAP has been demanded to finish a test in short time without sacrificing accuracy.

Use of a Backflush Needle with a Silicone Tip Cannula to Embed Lamellar Hole-Associated Epiretinal Proliferation.

Purpose: For the treatment of lamellar macular hole, the recent development of a lamellar hole-associated epiretinal proliferation (LHEP) embedding technique is likely to improve functional and anatomical results. However, the peeling of LHEP is often technically challenging. We have developed a new technique using a backflush needle with a silicone tip cannula that seems safer and more effective for use in LHEP embedding.

Fundus autofluorescence, optical coherence tomography and electroretinography abnormalities in a patient with digoxin retinopathy that resemble those in KCNV2-associated retinopathy.

Background: Digoxin related retinal toxicity causes blurred vision, photophobia, central scotoma, color vision abnormality, and electroretinography (ERG) abnormalities. Here, we report a case with transient abnormalities in vison, in which fundus autofluorescence (FAF), optical coherence tomography (OCT), and ERG findings resembled those in KCNV2 (potassium voltage-gated channel modifier subfamily V member 2)-associated retinopathy.

Case Report: An 89-year-old woman presented with complaints of acute blurred vision, nyctalopia, photophobia, and color vision abnormality.

Urokinase-type plasminogen activator promotes corneal epithelial migration and nerve regeneration.

Urokinase-type plasminogen activator (uPA) is a serine protease that plays a central role in the pericellular fibrinolytic system, mediates the degradation of extracellular matrix proteins and activation of growth factors, and contributes to the regulation of various cellular processes including cell migration and adhesion, chemotaxis, and angiogenesis. The corneal epithelium responds rapidly to injury by initiating a wound healing process that involves cell migration, cell proliferation, and tissue remodeling. It is innervated by sensory nerve endings that play an important role in the maintenance of corneal epithelial homeostasis and in the wound healing response.
