Aim and background: The study aims to determine the accuracy of utilizing a temporal view in the detection of a shallow anterior chamber (AC), in comparison to the conventional anterior view, by evaluation of photographs of the anterior segment of the eye.

Materials and methods: Two hundred fifty students who had completed basic undergraduate ophthalmology training as part of their medical education graded the AC depth in anterior segment photographs as "shallow" or "not shallow." Each eye was photographed from the anterior and temporal views. A total of 40 photographs of 20 eyes were provided.

Results: The ability to detect a shallow AC by temporal view had a sensitivity of 73.3%, compared to 63.2% in the anterior view. The specificity of the temporal view was better at 66.2% compared to the anterior view, which was 65.3%. The overall accuracy of the temporal view in detecting a shallow AC was higher than the anterior view (68.3 vs 64.7%, respectively). Combining both techniques increased the detection of a shallow AC to 88.3%.

Conclusion: In our study, the temporal view was more accurate in detecting a shallow AC compared to the anterior view. Integrating the temporal view of AC depth assessment with the traditional anterior view further improves the chances of detecting a shallow AC.

Aim: To evaluate the efficacy and safety of XEN® 45 gel stent implantation with a new surgical approach by ab externo transconjunctival technique.

Materials and methods: A total of 31 eyes of 31 patients affected with primary open-angle glaucoma (POAG) were treated with an ab externo transconjunctival approach. All the XEN gel stent implantations were performed at the Department of Ophthalmology of the Hospital of San Severino Marche, AV3- Asur Marche, Macerata, Italy between January 2021 and May 2021, and the follow-up duration was at least 6 months.

Results: A total of 31 eyes of 31 patients (mean age 65.6 ± 12.3 years; 20 males and 11 females) were included in the study. All the patients were affected by POAG. The mean intraocular pressure (IOP) was 25.3 ± 3.8 mm Hg, and the mean number of IOP-lowering topical medications before surgery was 2.7 ± 0.9. No intraoperative complications were reported. During the follow-up, one patient received medical treatment for a choroidal detachment, one patient had a 2 mm hyphema, and one patient had a partial migration of the stent in the anterior chamber. At the 1-month follow-up, the mean IOP was 12.8 ± 2.5 mm Hg and no patient was on IOP-lowering treatment, while at the 3-month and 6-month follow-ups, four patients were on treatment with one IOP-lowering drug. During the follow-up period, seven patients required postsurgical bleb needling, and one patient underwent a revision with PreserFlo® Microshunt implantation. The final mean IOP was 15.9 ± 2.7 mm Hg, and 27 out of 31 patients had an IOP of <18 mm Hg.

Conclusion: Ab externo transconjunctival XEN® 45 gel stent implantation represents a safe and effective surgical treatment approach.

Clinical significance: The ab externo approach represents a safe and effective technique, allowing early surgical timing and widening the group of patients who could benefit from the filtrating surgical technique before many years of topical medical treatment, which causes marked conjunctival alteration.
