Background And Objectives: We report on the incidence and course of early postoperative intraocular pressure (IOP) elevation and related surgical outcome following combined manual extracapsular cataract extraction (ECCE), using a sclerocorneal tunnel incision and trabeculectomy.
Patients And Methods: The combined procedure was the initial surgery in each eye. Intraocular pressure was measured during the first 4 days, at 1 week, and thereafter following surgery.
Results: Of 38 eyes (38 consecutive adults), postoperative IOP elevation to > 25 mm Hg was found in 7 eyes (18.4%) during the first 3 postoperative days. The IOP was reduced to < or = 20 mm Hg without hypotensive medication in 3 of them within the first 3-7 postoperative days, and remained so after 7-16 months (mean, 10.3 +/- 4.9 months). Each of the other 4 eyes underwent argon-laser suture lysis 8-10 days after surgery due to unstable IOP which rose to > 30 mm Hg. Two weeks after the operation and thereafter, ie, after 8-22 months (mean, 12.8 +/- 6.4 months), each of these 4 eyes necessitated 1-4 (mean, 2.5 +/- 1.3) hypotensive medications.
Conclusion: This study raises the possibility that in eyes with early IOP elevation, a delay in promoting aqueous outflow beyond a critical period during the first postoperative week might become a risk factor for full surgical success.

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.

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.

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

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.

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).
