Comparison of a new non-contact tonometer with Goldmann applanation [PDF]

Eye, 1989
A comparison of a new non-contact tonometer (Keeler Pulsair: Keeler UK Ltd) with the Goldmann applanation tonometer is reported. Measurements of intraocular pressure were obtained from 182 eyes of 94 patients. At low pressures (less than 10 mmHg) the candidate tonometer tended to overestimate pressures obtained with the Goldmann tonometer whilst at ...

Knowledge, Clinical Staging, and Barriers to Early Presentation of Diabetic Retinopathy in a Tertiary Eye Care Centre in Ghana: A Cross‐Sectional Study

Health Science Reports, Volume 8, Issue 10, October 2025.
ABSTRACT Background and Aims Diabetic retinopathy is the most common microvascular complication of diabetes mellitus and a leading cause of new‐onset blindness in populations of working age. Late presentation of patients to eye care facilities has been associated with the development of vision‐threatening complications.

Validation of the EYEMATE‐SC Suprachoroidal Pressure Transducer for Telemetric Measurement of Intraocular Pressure in Normal Ex Vivo Canine and Equine Globes—Preliminary Results

Veterinary Ophthalmology, Volume 28, Issue 5, Page 866-870, September 2025.
ABSTRACT Objective To determine the accuracy of the EYEMATE‐SC suprachoroidal tracer for telemetric tonometry in canine and equine globes. Procedures The EYEMATE‐SC sensor (7.8 mm × 3.8 mm × 1 mm) was implanted in the suprachoroidal space of four freshly enucleated normal canine and two normal equine eyes.

Variation of Bruch's membrane opening in response to intraocular pressure change during scleral lens wear, in a population with keratoconus

Ophthalmic and Physiological Optics, Volume 45, Issue 2, Page 405-415, March 2025.
Abstract Purpose The present study aimed to determine the potential impact of scleral lenses on intraocular pressure (IOP) by analysing the Bruch's membrane opening–minimum rim width (BMO‐MRW) while the lenses are worn, in a population with keratoconus.
