Useful Prediction of Phacodynamics by Scheimpflug Lens Densitometry in Patients over Age 70
Seminars in Ophthalmology, 2016To evaluate the relationship between lens density using the Scheimpflug system and phacodynamics in nuclear cataracts as related to patient age.In 262 eyes with nuclear cataracts, the objective lens density was determined by Pentacam Nucleus Staging (PNS) software while subjective grading was achieved using the Lens Opacities Classification System III (

Meandros Medical and Dental JournalPurpose: To explore the effects of COVID-19 on lens structure in children using Pentacam HR Scheimpflug corneal topography and lens densitometry (LD). Methods: This prospective case-control study involved patients aged 7 to 18 who were scheduled for ophthalmologic examination. Pentacam densitometry zones (PDZ 1, 2, and 3) were assessed in children who

Mapping normal lens transparency in adulthood: zone-specific densitometry trends
International OphthalmologyTo establish zone-specific normative values for lens densitometry in a healthy adult population and to evaluate age-related and biometric associations using Scheimpflug imaging.In this cross-sectional study, 272 eyes from 272 healthy adults aged 18-80 years (mean ± SD, 40.96 ± 15.13 years; 36.0% male) were analysed using the Pentacam HR (Oculus ...

Quantitative evaluation of lens transparency may aid the clinical assessment of normal and abnormal lenticular changes during childhood.Scheimpflug imaging enables objective measurement of crystalline lens light backscatter. While age-related increases in lens densitometry are well documented in adults, normative paediatric data remain limited. Because

The small degree of morbidity and a better postoperative visual acuity are the advantages of pneumatic retinopexy in comparison to encircling procedures in the treatment of retinal detachment. The injection of air or gas into the vitreous cavity can theoretically induce a cataract postoperatively.

Qualitative identification of rigid gas permeable contact lens materials by densitometry.
The CLAO journal : official publication of the Contact Lens Association of Ophthalmologists, Inc, 1999We describe a practical method to qualitatively identify polymethylmethacrylate (PMMA) and rigid gas permeable (RGP) contact lens materials.By progressive dilution of a saturated saline solution made with distilled or tap water and sodium chloride, we recorded comparative densitometry of rigid contact lens materials using a small hydrometer or by ...

Introduction: The objective of this study was to objectively investigate the progression of lens nuclear sclerosis after lens spearing pars plana vitrectomy (PPV) in patients with proliferative diabetic retinopathy (PDR). Methods: Comparison of Pentacam HR® Scheimpflug imaging-based lens densitometry (LD) of eyes with PDR-associated tractive retinal ...
