The Epidemiological and Clinical Findings from the Latvian Registry of Primary Congenital Glaucoma and Evaluation of Prognostic Factors.

Background and objectives: primary congenital glaucoma (PCG) is a rare, potentially blinding disease that affects children worldwide. The aim of the study was to describe the epidemiological and clinical characteristics, outcomes for newly diagnosed patients with PCG, as well as evaluate the prognostic factors that are related to the outcomes. Materials and Methods: a retrospective cohort study was conducted at a tertiary referral centre among patients diagnosed with PCG. Evaluation of the clinical data was performed preoperatively at three, six, and 12 months after the surgery and at the last follow-up. Results: during the 15 years of follow-ups, 24 eyes of 18 patients were diagnosed with PCG. Unilateral and bilateral PCG constituted 50% of cases each. A slight male predominance was observed (55.6% vs. 44.4%), with a relative risk of 1.3. The incidence of PCG was 1:19,033 live births. The mean age of the patients at the time of diagnosis was 10.1 ± 10.0 months, with a diagnostic delay of 2.0 ± 1.9 months. Furthermore, 75% of patients indicated an enlargement of an eyeball, followed by excessive tearing (58.3%) and corneal opacity (41.7%). After 85.9 ± 51.2 months, the mean intraocular pressure (IOP) value was 14.6 ± 4.9 mmHg. Surgical treatment provided sufficient IOP control in 75% of PCG cases at the last follow-up visit. The only prognostic factor that was related to the outcome of IOP control that was statistically significant was axial length at the time of diagnosis. Conclusions: the incidence of PCG in Latvia was 5.3 patients per 100,000 live births. PCG was more common among males than females with a relative risk of 1.3. The enlargement of an eyeball was the leading clinical sign.

Radius-Maumenee syndrome: A case series with a long-term follow-up.

The aim of the case series is to highlight the surgical challenges experienced like failed intervention, choroidal effusion, a postoperative cystoid macular oedema, and describe treatment options for Radius-Maumenee syndrome. Authors reported on 3 bilateral cases of Radius-Maumenee syndrome which underwent medical treatment, trabeculectomy with Mitomycin C, implantation with XEN45, Ahmed glaucoma valve, Baerveldt glaucoma implant, and cyclophotocoagulation.

Studies on the Effects of Hypercholesterolemia on Mouse Ophthalmic Artery Reactivity.

Atherogenic lipoproteins may impair vascular reactivity, leading to tissue damage in various organs, including the eye. This study aimed to investigate whether ophthalmic artery reactivity is affected in mice lacking the apolipoprotein E gene (ApoE-/-), a model for hypercholesterolemia and atherosclerosis. Twelve-month-old male ApoE-/- mice and age-matched wild-type controls were used to assess vascular reactivity using videomicroscopy. Moreover, the vascular mechanics, lipid content, levels of reactive oxygen species (ROS), and expression of pro-oxidant redox enzymes and the lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) were determined in vascular tissue. Unlike the aorta, the ophthalmic artery of ApoE-/- mice developed no signs of endothelial dysfunction and no signs of excessive lipid deposition. Remarkably, the levels of ROS, nicotinamide adenine dinucleotide phosphate oxidase 1 (NOX1), NOX2, NOX4, and LOX-1 were increased in the aorta but not in the ophthalmic artery of ApoE-/- mice. Our findings suggest that ApoE-/- mice develop endothelial dysfunction in the aorta by increased oxidative stress via the involvement of LOX-1, NOX1, and NOX2, whereas NOX4 may participate in media remodeling. In contrast, the ophthalmic artery appears to be resistant to chronic apolipoprotein E deficiency. A lack of LOX-1 expression/overexpression in response to increased oxidized low-density lipoprotein levels may be a possible mechanism of action.

Canaloplasty with mitomycin C after previous combined cataract surgery and Schlemm's canal microstent implantation.

We report on a 56-year-old male with primary open-angle glaucoma who underwent mitomycin C augmented canaloplasty enabling filtration in the right eye after cataract surgery combined with a Schlemm's canal microstent 3 years previously. He showed progressive glaucomatous optic neuropathy and was highly myopic (axial length 32.05 mm, spherical equivalent -18.75 dioptres in the right eye). Augmented canaloplasty was performed uneventfully and 360° catheterisation was achieved followed by the placement of a 10-0 polypropylene suture in Schlemm's canal. Intraocular pressure (IOP) in the first post-operative day was reduced from 19 to 6 mmHg. At 1-month follow-up IOP was 12 mmHg off glaucoma medications. The presence of a minimally invasive glaucoma surgery (MIGS) device did not hinder successful catheterisation of Schlemm's canal. Significant reduction of IOP was obtained in the early post-surgical period. No intra-operative complications were registered and only transient hyphema in early post-operative period was reported. This augmented canaloplasty could be an effective alternative to trabeculectomy even after Schlemm's canal microstent implantation.

[Attitude of patients to possible telemedicine in ophthalmology : Survey by questionnaire in patients with glaucoma]. / Einstellung von Patienten zu möglicher Telemedizin in der Ophthalmologie : Erhebung mittels Fragebogen bei Glaukompatienten.

BACKGROUND: The COVID-19 pandemic in 2020 and 2021 severely restricted the care of ophthalmology patients. Teleophthalmological services, such as video consultation or medical telephone advice could, at least partially, compensate for the lack of necessary controls in the case of chronic diseases; however, teleophthalmological options are currently still significantly underrepresented in Germany. OBJECTIVE: In order to determine the willingness of patients to use telemedicine and the virtual clinic, we conducted a survey using a questionnaire on the subject of teleophthalmology in university medicine patients with known glaucoma as a chronic disease during the first wave of the COVID-19 pandemic. METHODS: A total of100 patients were interviewed. The questionnaire contained 22 questions with multiple choice possible answers. The inclusion criterion was the presence of glaucoma as a chronic disease, age over 18 years, and sufficient linguistic understanding to answer the questions. The data were collected, analyzed and anonymously evaluated. RESULTS: In the patient survey it could be shown that the respondents with glaucoma are very willing to do teleophthalmology and that this would be utilized. Of the patients surveyed 74.0% would accept telemedicine and virtual clinics. Of the ophthalmological patients surveyed 54.0% stated that their visit to the doctor/clinic could not take place due to SARS-CoV­2 and 17.0% of the patients stated that the SARS-CoV­2 pandemic had changed their opinion of telemedicine. DISCUSSION: The acceptance of telemedicine in patients with chronic open-angle glaucoma seems surprisingly high. This has been increased even further by the SARS-CoV­2 pandemic. These results reflect a general willingness of patients with chronic eye disease but do not reflect the applicability and acceptance and applicability from a medical point of view; however, this form of virtual consultation is accepted by the majority of patients with glaucoma and could be considered for certain clinical pictures.

Isolated posterior capsule rupture after blunt eye injury.

Isolated posterior capsule rupture of the crystalline lens after blunt eye injury is a rare complication and demands a special surgical management strategy in order to achieve a good visual outcome.
