The AC properties such as central anterior chamber depth (ACD), and ACD and anterior chamber angle (ACA) in nasal, and temporal quadrants and the intraocular pressure (IOP) were recorded at the preoperative visit, 1st-day, last day of prone position, and 1st-month visits in both eyes.

Expanding the genetic spectrum of achromatopsia: novel CNGA3 and CNGB3 variants.

Purpose: Achromatopsia is a rare autosomal recessive disorder characterised by congenital pendular nystagmus, photophobia, decreased visual acuity, and impaired colour vision. Variants in the CNGA3 (Achromatopsia 2, MIM#216900) and CNGB3 (Achromatopsia 3, MIM#262300) genes account for the majority (more than 2/3) of cases, but genotype-phenotype correlations remain incompletely understood.

Methods: This study aims to expand the clinical and genetic spectrum of achromatopsia by analysing five patients from three families, including two novel variants in the CNGA3 and CNGB3.

Intellectual disability and retinitis pigmentosa due to a homozygous null variant: a clinical and genetic insight with review of the literature.

Introduction: Variations in the SCAPER gene are associated with Intellectual Developmental Disorder and Retinitis Pigmentosa (IDDRP), characterized by visual and neurological symptoms. Despite limited data, SCAPER plays a critical role in cell cycle regulation and ciliary function, which may explain its diverse phenotypic effects. This study aims to report a homozygous NM_020843.

Purpose: The objective of this study was to undertake a more comprehensive evaluation of the efficacy and comparative advantage of hyaluronic acid (HA) combined preparations in an experimental alkali model.

Method: In the present study, experimental chemical burns were induced in the right eyes of 22 New Zealand rabbits. The eyes were then divided into four groups for subsequent analysis: Trehalose + HA (Group T, n = 6); dexpanthenol + HA (Group P, n = 6); coenzyme Q10+vitamin E + HA (Group V, n = 6); and one control group (CG, n = 4).

Nanopore sequencing method for CTG18.1 expansion in TCF4 in late-onset Fuchs endothelial corneal dystrophy and a comparison of the structural features of cornea with first-degree relatives.

Background: To evaluate the relationship between the number of trinucleotide repeats (TNR) in late-onset Fuchs corneal endothelial dystrophy (FCED) and to compare the endothelial properties of FCED, first-degree relatives, and controls.

Methods: Blood samples were collected from FCEDs to determine TNR number. The FCED patients, first-degree relatives, and controls were examined with specular microscopy for central corneal thickness (CCT), endothelial cell density (ECD), pleomorphism and polymegatism, and with corneal topography for specific indicators such as (i) displacement of thinnest point of cornea, (ii) loss of isopachs, (iii) focal posterior surface depression towards anterior chamber.

Long term outcomes of Yamane technique in various indications.

Introduction: To describe the clinical and refractive outcomes of Yamane transconjunctival sutureless intrascleral intraocular lens (SIS IOL) fixation technique in aphakic and dislocated IOLs.
