We studied the change in intraocular pressure in 373 consecutive eyes undergoing cataract extraction with intraocular lens implantation between Jan. 1, 1981, and May 31, 1982. There was a mean increase in intraocular pressure of 0.1 mm Hg following this surgery. This increase, however, was not statistically significant (P greater than .5). There was a mean rise in pressure of 0.8 mm Hg in the eyes undergoing intracapsular surgery and a mean fall in pressure of 0.6 mm Hg in the eyes undergoing extracapsular surgery (P less than .05). The change in pressure was unrelated to age, surgeon, or lens type. The results of a separate analysis of 16 eyes with a preoperative diagnosis of glaucoma and eight eyes with ocular hypertension were similar.

Progressive anterior segment involvement of an infant with corneoscleral juvenile xanthogranuloma refractory to topical steroids.
Am J Ophthalmol Case Rep
December 2024
Bascom Palmer Eye Institute, University of Miami Miller School of Medicine, Miami, FL, USA.
Purpose: To report a case of corneoscleral juvenile xanthogranuloma (JXG) with progressive anterior segment involvement refractory to topical steroids.
Observations: A 4-month-old male was referred for a new-onset subconjunctival lesion in the right eye. He was found to have a thickened, yellow corneoscleral lesion and hyphema, presumed to be ocular JXG.
Relationship Between Axial Length and Retinal Oxygen Dynamics in Adults With Myopia.
Transl Vis Sci Technol
January 2025
Medical School of Chinese People's Liberation Army, Beijing, China.
Purpose: The purpose of this study was to evaluate the correlation between axial length (AL) and retinal oxygen dynamic parameters in adult patients.
Methods: This was an observational cross-sectional study with 79 Chinese adults with myopia aged 18 to 37 years. All participants underwent AL measurements, cycloplegic refraction, and other ophthalmic examinations.
Using a Theoretical Model to Assess the Impact of Vascular Risk Factors on Autoregulation in the Retina.
Invest Ophthalmol Vis Sci
January 2025
Department of Ophthalmology, Icahn School of Medicine at Mount Sinai Hospital, New York, New York, United States.
Purpose: Vascular impairments, including reduced capillary density (CD), impaired autoregulation capacity (Reg), and elevated intraocular pressure (IOP), have been identified as significant contributors to glaucomatous disease. This study implemented a theoretical model to quantify the impact of these impairments on retinal blood flow and oxygenation as intraluminal pressure (Pa) is varied.
Methods: A theoretical model of the retinal vasculature was used to simulate reductions in CD by 10% (early glaucoma) and 30% to 50% (advanced glaucoma), a range in autoregulation capacity from 0% (totally impaired) to 100% (totally functional), and normal (15 mm Hg) and elevated (25 mm Hg) levels of IOP.
Tubulin Acetylation Enhances Microtubule Stability in Trabecular Meshwork Cells Under Mechanical Stress.
Invest Ophthalmol Vis Sci
January 2025
Department of Ophthalmology, Duke Eye Center, Duke University, Durham, North Carolina, United States.
Purpose: To study the roles of tubulin acetylation and cyclic mechanical stretch (CMS) in trabecular meshwork (TM) cells and their impact on outflow pathway physiology and pathology.
Methods: Primary TM cell cultures were subjected to CMS (8% elongation, 24 hours), and acetylated α-tubulin at lysine 40 (Ac-TUBA4) was assessed by western blotting and immunofluorescence. Enzymes regulating tubulin acetylation were identified via siRNA-mediated knockdowns of ATAT1, HDAC6, and SIRT2.
Impact of mitomycin C on surgical outcomes of PAUL glaucoma implant in neovascular glaucoma: 12-month follow-up results.
Eur J Ophthalmol

Department of Ophthalmology, University of Health Sciences, Basaksehir Cam and Sakura City Hospital, Istanbul, Turkey.
Purpose: To evaluate the effectiveness of the PAUL Glaucoma Implant (PGI) and the adjunctive impact of intraoperative Mitomycin C (MMC) on surgical outcomes in patients with neovascular glaucoma (NVG).
Methods: This retrospective, comparative study included NVG patients who underwent PGI implantation. The cohort was divided into two groups: Group 1 (PGI without MMC) and Group 2 (PGI with MMC).
