“…A high prevalence of narrow angles (36.9%) was found in mainland population aged [ 50 years [26], which might contribute to the high risk of PAS after CLASS. Cataract surgery can deepen anterior chamber and increase the width of anterior chamber angle in Chinese subjects [27]. Meanwhile, a younger age and higher baseline IOP also increased the risk of PAG in CLASS group.…”

Introduction:To compare 1-year outcomes of CO 2 laser-assisted sclerectomy surgery (CLASS) alone or combined with phacoemulsification (CLASS ? Phaco) in eyes with primary openangle glaucoma (POAG). Methods: This was a prospective, comparative, case series study. A total of 46 eyes with POAG underwent CLASS or CLASS ? Phaco were followed up for 1 year. The primary outcomes included changes in intraocular pressure (IOP), medication and best corrected visual acuity (BCVA). The secondary outcomes were success rate, functional bleb, postoperative laser intervention and complications. Results: CLASS alone resulted in a greater IOP reduction compared with CLASS ? Phaco. BCVA improved remarkably in CLASS ? Phaco group, but there was no difference in BCVA before and after CLASS. The number of antiglaucoma medications significantly decreased at 12 months postoperatively in both groups. Functional blebs were more commonly seen in the CLASS than combination group. The overall success rate was higher in the CLASS than CLASS ? Phaco group at 1 year after surgery. The incidence of peripheral anterior synechiae (PAS) in CLASS ? Phaco group was significantly lower than that of CLASS alone. Conclusion: CLASS alone achieved a greater IOP reduction, more common functional bleb formation and a higher success rate compared to CLASS combined with Phaco, while combination surgery yielded a better BCVA improvement and a lower PAS incidence than CLASS alone. Both surgical strategies have favorable safety and efficacy among POAG patients. Combined surgery could be a viable option for patients with co-existing POAG and cataract.

“…13 When changes in anterior chamber angle which lead to decrease in IOP were compared between eyes with narrow angle and normal eyes, it was seen that these changes never reached the eyes of normal values. 14 Zuo et al included patients with medically uncontrolled filtered Primary angle closure glaucoma. They reported decrease IOP and improved vision in these patients.…”

Objective: To compare the changes in Retinal Nerve Fiber Layer (RNFL) thickness and Intraocular Pressure (IOP) after phacoemulsification in patients with glaucoma versus without glaucoma. Methods: This was a quasi-experimental study, done at Lahore General Hospital, from January 2021 to December 2021. Patients with senile cataract were divided into two groups. One group included 40 patients, with ≥40 years of age and diagnosed with primary open angle glaucoma compared with a second group of 40 age-matched controls without glaucoma, undergoing phacoemulsification and Intraocular Lens Implantation (IOL). Goldman Applanation Tonometer (GAT) and Spectral Domain Optical Coherence Tomography (SD-OCT) were used to record IOP and RNFL thickness, before surgery, at one week and one month after surgery. The results were compared with baseline readings and also between the two groups. Results: A total of 80 patients were included in the study. Mean age was 60.3±7.9 years with male to female ratio of 1:1. Mean change in RNFL thickness in glaucomatous eyes group and non-glaucomatous Eyes group from pre-operative baseline was 11.33±4.30µm and 4.08±2.59µm respectively after one month (p-value<0.001). Difference of mean change in RNFL thickness from baseline was statistically significant between both groups (p< 0.001). Difference of mean change in IOP from baseline at four weeks was statistically significant in the individual groups but between both groups was statistically insignificant (p= 0.234) Conclusion: Phacoemulsification results in increase in RNFL thickness and decrease in IOP, which are good prognostic factors in control of glaucoma. However, a mean change of IOP of 1mmHg in glaucoma patient does not affect management of glaucoma. doi: https://doi.org/10.12669/pjms.39.1.6531 How to cite this: Shahid M, Saleem Z, Malik TG, Farqaleet M.

“…However, the results about persistent shallow anterior chamber depth after surgery are different from previous studies [7][8] . Another study showed that in patients with shallow anterior chamber, anterior chamber depth didn't recover to normal level compared with patients of normal anterior chamber after phacoemulsification by anterior segment swept-source OCT [9] . But the data of ciliary body structure was not mentioned in the study [9] , due to OCT could not measure the ciliary body as UBM.…”
