“…Different severity of underlying eye disease may have led to different responses to ECP regardless of anterior or Pars Plana approach. In addition, it is well known that phacoemulsification or vitrectomy may affect IOP . Thus, it is possible that the phacoemulsification frequently performed concomitantly with anterior ECP and the vitrectomy performed concomitantly with ECP‐plus may have affected IOP independent of ECP approach.…”

Importance This is the first study to compare the efficacy and safety of endocyclophotocoagulation (ECP) via pars plana (ECP‐plus) with ECP via limbus (anterior ECP) for treating glaucoma. Background There is no direct comparison of treatment outcomes between ECP‐plus and anterior ECP. Design Retrospective study. Participants Fifty‐four consecutive patients. Methods Fifty‐eight eyes from 54 consecutive patients underwent anterior ECP (33 eyes) or ECP‐plus (25 eyes) with 2‐year follow‐up. Linear mixed model was used to analyse the surgical outcomes. Main Outcome Measures Intraocular Pressure (IOP) was the primary outcome. Secondary outcomes were best‐corrected visual acuity, number of glaucoma medications, complications and success rate. Results Compared to anterior ECP, patients in the ECP‐plus group had lower IOP (estimate of effect size [EES] = −3.7 mmHg, P = 0.023) and used fewer number of glaucoma medications (EES = −1.11, P = 0.003), after adjusting for degrees of treatment, preoperative IOP, and presence of combined ECP and phacoemulsification procedure. Patients with ECP‐plus achieved a higher success rate at 2 years postoperatively (80% vs 33.3%, P < 0.001). The decrease in IOP between the preoperative and last follow‐up visit was greater in the ECP‐plus group compared to the anterior ECP group (14.3 mmHg (52%) vs 5.2 mmHg (24%), P = 0.001). There was no significant difference in complication rates between the two groups (28% vs 33%, P = 0.561). Conclusions and Relevance Anterior ECP and ECP‐plus have a similar safety profile, and ECP‐plus may offer superior IOP control for the management of glaucoma.

“…In order to determine the correct lens position, as well as the IOL power obtained using keratometry and axial length values, the ACD must be measured accurately preoperatively. The ACD is particularly important in the diagnosis and treatment of glaucoma patients (16). Yagci et al (17) found that there was an increase in the ACD as well as the ACA in their study results, which revealed an inverse correlation with preoperative values.…”

The goal of this study was to compare measurements of values such as the anterior chamber angle (ACA), thickness of the iris, thickness of the cornea, and the angle-opening distance (AOD) of eyes with primary open-angle glaucoma before and after undergoing phacoemulsification with intraocular lens implantation using anterior segment optical coherence tomography (AS-OCT). Methods: The data of 49 eyes of 39 glaucoma patients who presented at the Cataract and

“…All the complementary techniques for imaging the ACA should be better considered as complementary exams to slit-lamp gonioscopy and not as alternatives [ 41 ]. OCT has shown a potential role in predicting the outcome of laser treatments [ 42 , 43 , 44 , 45 ]. Digital gonioscopy has been shown useful in documenting post-operative and abnormal findings of the ACA and has a great potential for teaching gonioscopy.…”

Moving beyond the Slit-Lamp Gonioscopy: Challenges and Future Opportunities

et al. 2021

After almost a century from its introduction in clinical practice, slit-lamp gonioscopy is still considered the reference standard for evaluating the anterior chamber angle (ACA). Gonioscopy is essential for diagnosing angle closure disease, and ACA features are included in glaucoma’s diagnostics and treatments algorithms. However, shortcomings of slit-lamp gonioscopy include a steep learning curve, lack of agreement between examiners and poor documentation. Thanks to advances in miniaturization and computing, new instruments for digital gonioscopy have been developed and marketed. This narrative review focuses on the Gonioscope GS-1, which permits semi-automated circumferential documentation of the ACA in real-colour photographs. Advantages and disadvantages of GS-1 compared with slit-lamp gonioscopy and other ACA imaging technologies such as optical coherence tomography are discussed. Finally, potential opportunities offered by this device for telemedicine, virtual clinics, and automatic classification with deep learning are presented.

Novel Gonioscopy Score and Predictive Factors for Intraocular Pressure Lowering After Phacoemulsification

Abstract: Preoperative predictors for IOP reduction after cataract surgery were preoperative IOP, ACD, gonioscopy score, and IOP/ACD ratio. The IOP/ACD ratio and gonioscopy score can be easy parameters to obtain and may help clinicians to estimate the IOP reduction after phacoemulsification.
