Test–retest variability of the full‐field stimulus test in patients with retinitis pigmentosa: REPEAT Study Report No. 4

Acta Ophthalmologica, Volume 104, Issue 1, Page 89-97, February 2026.
Abstract Purpose To evaluate test–retest variability (TRV) of the full‐field stimulus test (FST) in patients with retinitis pigmentosa (RP) and poor best‐corrected visual acuity (BCVA; ≤20/50 Snellen; ≥0.40 logMAR), and to assess the reliability of FST as a clinical endpoint in future RP trials.

Argon Laser Peripheral Iridoplasty and Argon Laser Pupilloplasty: Alternative Management for Medically Unresponsive Acute Primary Angle Closure

Journal of Ophthalmology, Volume 2019, Issue 1, 2019., 2019
Objective. To introduce the combined laser technique, argon laser peripheral iridoplasty (ALPI) and argon laser pupilloplasty (ALPP), in the management of medically unresponsive acute primary angle closure (APAC). Design. Retrospective study. Methods. We retrospectively reviewed the records of 23 patients (27 eyes) with APAC, who were applied ALPI and ...

Exploring Glaucoma: From Pathogenesis to Emerging Diagnostic and Management Strategies

Journal of Ophthalmology, Volume 2025, Issue 1, 2025.
Glaucoma is a leading cause of irreversible blindness globally, affecting millions of individuals. It encompasses a group of progressive optic neuropathies characterized by retinal ganglion cell loss and visual field deterioration, often associated with elevated intraocular pressure.

Pulse Waveform Analysis of the Ocular Blood Flow Using Laser Speckle Flowgraphy before and after Glaucoma Treatment

Journal of Ophthalmology, Volume 2019, Issue 1, 2019., 2019
Although reduction in intraocular pressure (IOP) is the principle of glaucoma treatment, impaired ocular blood flow is believed to play a role in the progression of glaucoma. This study evaluated the effect of glaucoma treatment on pulse waveforms for optic nerve head (ONH) microcirculation in patients with glaucoma. Fifty‐one subjects were included on

Mechanisms of cone sensitivity loss in retinitis pigmentosa

Ophthalmic and Physiological Optics, Volume 44, Issue 3, Page 605-612, May 2024.
Abstract Purpose To explore the mechanisms of cone sensitivity loss in retinitis pigmentosa by combining two‐colour perimetry with threshold versus intensity (tvi) testing. Methods Seven subjects with autosomal recessive retinitis pigmentosa and 10 normal subjects were recruited and underwent perimetric testing of one eye using 480‐ and 640‐nm Goldman ...

Metamorphopsia Score and Central Visual Field Outcomes in Diabetic Cystoid Macular Edema

BioMed Research International, Volume 2018, Issue 1, 2018., 2018
Aim. To detect abnormality of the visual function in naïve patients with cystoid diabetic macular edema (DME) using M‐charts, Amsler test, and white on white (W/W) and blue on yellow (B/Y) perimetry. Methods. There were 64 eyes included in the study: 30 eyes with DME, 22 eyes with diabetes without DME, and 12 eyes of normal subjects.

Predicting perimetric defects from en face maps of retinal nerve fibre layer reflectance

Ophthalmic and Physiological Optics, Volume 44, Issue 3, Page 613-625, May 2024.
Abstract Purpose To develop criteria to predict visual hemifields with deep perimetric defects based on retinal nerve fibre layer (RNFL) reflectance, in a transparent process whose components can be assessed by independent laboratories analysing data from their own small groups.

Melatonin suppression by light involves different retinal photoreceptors in young and older adults

Journal of Pineal Research, Volume 76, Issue 1, January 2024.
Abstract Age‐related sleep and circadian rhythm disturbances may be due to altered nonvisual photoreception. Here, we investigated the temporal dynamics of light‐induced melatonin suppression in young and older individuals. In a within‐subject design study, young and older participants were exposed for 60 min (0030‐0130 at night) to nine narrow‐band ...

The role of standard automated perimetry and newer functional methods for glaucoma diagnosis and follow-up

Indian Journal of Ophthalmology, 2011
Automated perimetry has become the mainstream for assessment of functional glaucomatous loss and progressive damage. Recent improvements with the Swedish interactive thresholding algorithm (SITA) strategy and the guided progression analysis (GPA) have ...
