“…Cyclodestruction is an effective method for ophthalmologists to reduce intraocular pressure in glaucoma patients. Recently, ultrasound cycloplasty has been proved to be an effective and safe method for the treatment of glaucoma [11,12]. UCP generates high-intensity focused ultrasound through micro transducers, inducing ciliary body coagulation so as to treat glaucoma.…”

Objectives To explore effects of ultrasound cycloplasty (UCP) in glaucoma patients, aiming to evaluate the efficacy and safety of UCP. Methods Twenty-two glaucoma patients (23 eyes) who received UCP treatment at the Ophthalmology Department of Nanchang First Hospital from July 2020 to September 2022 were selected.Intraocular pressure (IOP), number of anti-glaucoma agents, best corrected visual acuity (BCVA) and eye pain scores of the patients before and 1, 3, 7 days, 1, 3 and 6 months after treatment were recorded.The complications during treatment and after treatment were also observed.The corneal curvature, pupil size, corneal thickness and anterior chamber depth of pentacam before and 1 day, 1 and 6 months after treatment were measured. Results The preoperative IOP, number of anti-glaucoma agents, and eye pain scores were 37.35 ± 13.79 mmHg, average 3.35 ± 1.23 and 4.39 ± 2.15, which were decreased significantly at each time point after UCP treatment (P < 0. 01). The IOP decrease rates were 33.31%, 45.68%, 46.32%, 47.23%, 41.93%, and 48.46%, respectively. The postoperative IOP reduction at 1, 3 and 7 days, 1, 3 and 6 months were significantly correlated with preoperative IOP (r = 0.719, 0.750, 0.797, 0.661,0.515 and 0.607, all P < 0.05). No serious complication was observed throughout the treatment and the follow-up.There was a temporary change in anterior keratometry 1 day after UCP treatment. BCVA, pupil diameter, corneal thickness and anterior chamber depth remained unchanged. Conclusion UCP was demonstrated to be effective in decreasing IOP, IOP-lowering medications and pain scores in patients with glaucoma. It’s well-tolerated without intraoperative or postoperative complications.

“…Intraocular pressure (IOP) is an important parameter for the early detection of certain ocular pathologies, such as choroidal detachment or glaucoma [1,2]. Its usual distribution in the population ranges from 10 to 21 mmHg, with a mean value of approximately 15 mmHg in healthy adults [3].…”

To compare intraocular pressure (IOP) values at different time points, both in the total sample and according to iridocorneal angle aperture, to assess whether IOP fluctuations were constant throughout the day, and to examine correlations with other factors. MethodsOver a single day, the IOP of 34 volunteers was measured at three-hour intervals from 9:00 a.m. to 6:00 p.m. To avoid any IOP value being affected by other measurements, anamnesis, slit-lamp evaluation (with iridocorneal angle measurement), and refractive status were performed after the final measurement. The differences between IOP values at different time points and IOP fluctuation at three-hour intervals were compared by ANOVA and Friedman test, respectively, both for the total group and according to iridocorneal angle aperture. For relationships, Pearson's correlation was performed for parametric variables and Spearman's correlation for nonparametric variables. ResultsSignificant differences were observed in IOP between time points for the total sample (p < 0.001), but not for a narrow-angle group (p = 0.058). No significant differences were found in IOP fluctuations at three-hour intervals either in the total sample or according to angle aperture (all p ≥ 0.332). There was a positive correlation of IOP at different time points (all r ≥ 0.646, all p < 0.001) but no relationship with spherical equivalent, age, or sleep duration (all p ≥ 0.057). IOP at 12:00 p.m. was correlated with a 12:00 p.m. to 3:00 p.m. fluctuation (r = 0.428, p = 0.012); and IOP fluctuation between 9:00 a.m. and 12:00 p.m. was correlated with age (r = 0.485, p = 0.004). ConclusionAs IOP decreases from morning until at least 6:00 p.m., measuring these two values during clinical evaluation is essential for the effective monitoring and prevention of IOP-related diseases.
