What optic disc parameters are most accurately assessed using the direct ophthalmoscope? [PDF]

Eye, 2001
It has been suggested that over-reliance on the cup-to-disc ratio is a major factor in the misinterpretation of the optic disc. In spite of this optometrist assessment of the optic disc tends to be restricted to measurement of the cup-to-disc ratio and cup depth only.

Population‐Based Cohort Study for Development of National Retinopathy of Prematurity Screening Criteria

Acta Paediatrica, Volume 115, Issue 3, Page 671-678, March 2026.
ABSTRACT Aim Screening criteria for retinopathy of prematurity (ROP) vary among countries. Early detection of ROP and minimising the burden of screening are important. Methods We analysed data from very preterm infants born in Switzerland between 2006 and 2022.

Visual Function Assessment in Geographic Atrophy: A Review

Clinical &Experimental Ophthalmology, Volume 54, Issue 2, Page 260-274, March 2026.
ABSTRACT Geographic atrophy (GA) causes significant vision impairment and reduction in vision‐related quality of life. Fundus autofluorescence (FAF) is the gold standard of structural assessment of GA but is a surrogate marker for vision loss, which can be assessed by tests of visual function and functional vision.

Imaging Canine Post‐Trabecular Aqueous Outflow Pathways: Effect of Acute Intraocular Pressure Elevation in Normal Eyes

Veterinary Ophthalmology, Volume 29, Issue 2, March 2026.
ABSTRACT Purpose To investigate the relationship between increased intraocular pressure (IOP) and the structure of the post‐trabecular aqueous outflow tract of dogs. Methods Ex vivo aqueous angiography (AA) and anterior segment optical coherence tomography (OCT) were performed concurrently in 19 normal canine eyes, following cannulation and ...
