Glaucoma is a group of chronically progressive disorders of the optic nerve. In this article, we present the epidemiology of and risk factors for glaucoma, as well as the diagnostic work-up and ...treatment options.
This review is based on pertinent publications retrieved by a selective search in Medline and the Cochrane Library, supplemented by further articles chosen by the authors.
In Europe, the prevalence of glaucoma is 2.93% among persons aged 40 to 80 years. The prevalence rises with age, reaching 10% in persons over 90 years old. The available diagnostic methods include ophthalmoscopy, tonometry, perimetry, and imaging techniques. The treatment of glaucoma is focused on lowering the intraocular pressure with topical drugs, laser therapy, and glaucoma surgery. In patients with manifest glaucoma, lowering the intraocular pressure prevents the progression of visual field defects, with a number needed to treat of 7.
The diagnostic evaluation of glaucoma rests on multiple pillars, all of which must be considered for establishing the diagnosis and defining the desired target pressure: these are, among others, the intraocular pressure and ocular function and morphology. Individually tailored pressure-lowering treatment should be evaluated in regularly scheduled follow-up visits for assessment of function and morphology and adjusted as necessary to minimize the risk of progression.
To assess long-time results of primary surgical treatment in children with glaucoma after congenital cataract surgery.
A retrospective study of 37 eyes from 35 children with glaucoma after congenital ...cataract surgery, who underwent surgery between 2011 and 2021 at the Childhood Glaucoma Center, University Medical Center Mainz, Germany. Only children, who received a primary glaucoma surgery in our clinic within the given time (n = 25) and had at least one-year follow-up (n = 21), were included in the further analysis. The mean follow-up time was 40.4±35.1 months. The primary outcome was the mean reduction in IOP (in mmHg) from baseline to follow-up visits after the surgery, measured with Perkins tonometry.
8 patients (38%) were treated with probe trabeculotomy (probe TO), 6 (29%) with 360° catheter-assisted trabeculotomy (360° TO) and 7 (33%) with cyclodestructive procedures. IOP was significantly reduced after probe TO and 360° TO after 2 years, from 26.9 mmHg to 17.4 mmHg (p<0.01) and 25.2 mmHg to 14.1 mmHg (p<0.02), respectively. There was no significant IOP reduction after cyclodestructive procedures after 2 years. Both, probe TO and 360° TO led descriptively to eye drops reduction after 2 years, from 2.0 to 0.7 and 3.2 to 1.1. The reduction was not significant.
In glaucoma after congenital cataract surgery, both trabeculotomy techniques, lead to good reduction of IOP after 2 years. There is a need for a prospective study with comparison to the use of glaucoma drainage implants.

Objective
Untreated individuals with glutaric aciduria type 1 (GA1) commonly present with a complex, predominantly dystonic movement disorder (MD) following acute or insidious onset striatal damage. ...Implementation of GA1 into newborn screening (NBS) programs has improved the short‐term outcome. It remains unclear, however, whether NBS changes the long‐term outcome and which variables are predictive.
Methods
This prospective, observational, multicenter study includes 87 patients identified by NBS, 4 patients missed by NBS, and 3 women with GA1 identified by positive NBS results of their unaffected children.
Results
The study population comprises 98.3% of individuals with GA1 identified by NBS in Germany during 1999–2016. Overall, cumulative sensitivity of NBS is 95.6%, but it is lower (84%) for patients with low excreter phenotype. The neurologic outcome of patients missed by NBS is as poor as in the pre‐NBS era, and the clinical phenotype of diagnosed patients depends on the quality of therapeutic interventions rather than noninterventional variables. Presymptomatic start of treatment according to current guideline recommendations clearly improves the neurologic outcome (MD: 7% of patients), whereas delayed emergency treatment results in acute onset MD (100%), and deviations from maintenance treatment increase the risk of insidious onset MD (50%). Independent of the neurologic phenotype, kidney function tends to decline with age, a nonneurologic manifestation not predicted by any variable included in this study.
Interpretation
NBS is a beneficial, disease‐changing intervention for GA1. However, improved neurologic outcome critically depends on adherence to recommended therapy, whereas kidney dysfunction does not appear to be impacted by recommended therapy. Ann Neurol 2018;83:970–979
Purpose
To assess surgical success and the post‐operative development of intraocular pressure between XEN45® gelstent, Preserflo® MicroShunt and trabeculectomy with mitomycin C.
Methods
Data from 105 ...eyes from 105 patients of matched cases with refractory open‐angle glaucoma, who underwent surgery between January 2019, and August 2020, were evaluated. Patients underwent either stand‐alone XEN gelstent insertion with Mitomycin C, stand‐alone Preserflo with Mitomycin C or trabeculectomy with Mitomycin C. The primary outcome was the proportion of complete surgical success at 6 months post‐operatively (i.e. intraocular pressure between 5mmHg and 18mmHg, no revision surgery, no loss of light perception and no post‐operative pharmaceutical antiglaucomatous treatment). The reduction of intraocular pressure after 6 months, the classes of antiglaucomatous medication used post‐operatively, best‐corrected visual acuity, spherical refractive errors and astigmatism were assessed as secondary outcomes.
Results
We included 35 eyes in each group. After 6‐month follow‐up, complete success was 73.5% 95%‐CI: 57.9%–89.2% in the trabeculectomy group, 51.4% 95%‐CI: 34.0%–68.8% in the XEN group and 74.2% 95%‐CI: 57.9%–90.5% in the Preserflo group (p = 0.08). Regarding secondary outcomes, the reduction of intraocular pressure was 12.1 ± 7.9 mmHg in the trabeculectomy group and was thereby 5.8 95%‐CI: 2.2–9.6 mmHg greater compared with the XEN group (p < 0.001) and 4.8 95%‐CI: 0.9–8.7 mmHg higher than the Preserflo group (p = 0.01).
Conclusions
No statistically significant differences were found between trabeculectomy, XEN45® gelstent implantation and Preserflo® MicroShunt implantation regarding surgical success after 6 months. Yet reduction in intraocular pressure was significantly higher in the trabeculectomy group. However, all three interventions resulted in sufficiently low post‐operative intraocular pressure and may therefore be considered individually for glaucoma treatment.
Glaucoma is a neurodegenerative disease, leading to thinning of the retinal nerve fibre layer (RNFL). The exact influence of ocular, cardiovascular, morphometric, lifestyle and cognitive factors on ...RNFL thickness (RNFLT) is unknown and was analysed in a subgroup of the Gutenberg Health Study (GHS).
Global peripapillary RNFLT was measured in 3224 eyes of 1973 subjects (49% female) using spectral-domain optical coherence tomography (SD-OCT). The association of age, sex, ocular, cardiovascular, morphometric, lifestyle and cognitive factors on RNFLT was analysed using Pearson correlation coefficient and fitting a linear mixed model.
In the univariable analysis highest correlations were found for axial length (r = -0.27), spherical equivalent (r = 0.24), and glaucoma (r = -0.15) (p<0.0001, respectively). Other significant correlations with RNFLT were found for age, sex, intraocular pressure, systemic hypertension and systolic blood pressure, previous eye surgery, cholesterol, homocysteine, history of coronary artery disease, history of myocardial infarction, apnoea, diabetes and alcohol intake, p<0.05, respectively. Body length, body weight, BMI, diastolic blood pressure, blood glucose, HbA1c, history of apoplexy, cognitive function, peripheral artery disease, tinnitus, migraine, nicotine intake, central corneal thickness, and pseudophakia were not significantly correlated with RNFLT. The regression model revealed a significant relationship between RNFLT and age in decades (p<0.02), spherical equivalent (p<0.0001), axial length (p<0.0001), glaucoma (p<0.0001), tinnitus (p = 0.04), apnoea (p = 0.047), homocysteine (p = 0.05) and alcohol intake >10g/d for women and >20g/d for men (p = 0.02). Glaucoma, apnoea, higher homocysteine, higher alcohol intake and higher axial length as well as age were related to decreased RNFLT while higher spherical equivalent or history for tinnitus were related to thicker RNFL.
RNFLT is related to age, ocular parameters and lifestyle factors. Considering these parameters in normative databases could improve the evaluation of peripapillary RNFLT. It is necessary to evaluate if a reduction of alcohol intake as well as the therapy of apnea or high homocysteine levels could positively influence RNFLT.

Purpose
To evaluate the diagnostic ability of Fourier-domain optical coherence tomography (FD-OCT) measurements in glaucoma patients, patients with ocular hypertension, and normal subjects.
Methods
...Ninety-three participants with open-angle glaucoma (OAG), 58 patients with ocular hypertension (OHT), and 60 healthy control subjects were included in the study. All study participants underwent FD-OCT imaging. Retinal ganglion cell complex (GCC), macular thickness, peripapillary retinal nerve fiber layer thickness (RFNL), and optic nerve head parameters (ONH) were measured in each participant. The diagnostic ability was evaluated using area under the receiver operating characteristics curves (AUROC).
Results
Glaucoma patients showed a significant reduction in GCC and macular retinal thickness compared to patients with OHT and normal subjects. No differences in GCC were found between the patients with OHT and normal subjects. The best diagnostic ability in the comparison between glaucoma and normal subjects after adjusting for age was found for cup-to-disc ratio (AUROC = 0.848), RNFL average thickness (AUROC = 0.828), and GCC global loss volume (AUROC = 0.805). The diagnostic power of the best GCC, RNFL, and ONH parameter did not show differences beyond random variation (
p
> 0.05).
Conclusions
Imaging of the GCC using FD-OCT (RTVue-100) has a comparable diagnostic ability to RNFL and ONH measurements in distinguishing between glaucoma patients and healthy subjects. No differences were found between patients with OHT and normal subjects with regard to ONH, RNFL, and GCC parameters.
After the open bleb revision following PreserFlo, the mean postoperative intraocular pressure (IOP) was lowered from 26.4 ± 9.9 mm Hg to 12.9 ± 5.6 mm Hg at 1 month and 15.9 ± 4.1 mm Hg at 12 months.
...The purpose of this study was to evaluate the effectiveness and safety of an open bleb revision with mitomycin-C (MMC) for bleb fibrosis after PreserFlo MicroShunt implantation.
We performed a retrospective analysis of 27 consecutive patients with bleb fibrosis after PreserFlo MicroShunt Implantation that underwent an open revision with MMC 0.2 mg/mL applied for 3 minutes at the Department of Ophthalmology of the Mainz, University Medical Center, Mainz, Germany. Demographic data, such as age, sex, glaucoma type, number of glaucoma medications, IOP before and after PreserFlo implantation and revision, complications, and reoperations within 12 months, were analyzed.
Twenty-seven patients (27 eyes) received an open revision after previous PreserFlo Microshunt implantation and consecutive bleb fibrosis. The mean preoperative IOP was 26.4 ± 9.9 mm Hg before revision, 7.0 ± 2.7 mm Hg (P < 0.001) in the first week after the revision, and 15.9 ± 4.1 mm Hg at 12 months (P = 0.02). Four patients needed IOP-lowering medication after 12 months. One patient had a positive Seidel test and needed a conjunctival suture. Four patients required a second procedure due to recurring bleb fibrosis.
At 12 months, open revision with MMC for bleb fibrosis a failed PreserFlo implantation effectively and safely reduced IOP with a similar medication burden.
This study investigated whether prematurity and associated factors or prenatal growth restriction have long-term effects on the peripapillary retinal nerve fiber layer (pRNFL) in adulthood.
...Retrospective cohort study.
The Gutenberg Prematurity Eye Study (GPES) is a retrospective cohort study with a prospective ophthalmologic examination in Germany. Selected individuals born term and preterm (age 18-52 years) were examined with spectral-domain optical coherence tomography (SD-OCT) in adulthood, and perinatal medical charts were reviewed. The pRNFL thickness was measured using SD-OCT. Univariate and multivariable linear regression analyses were conducted to investigate associations between pRNFL and gestational age (GA; categorical), birth weight percentile (categorical), retinopathy of prematurity (ROP) occurrence, and treatment and other perinatal parameters with adjustment for age, sex, and spherical equivalent.
In total, 766 eyes of 406 preterm and full-term individuals were included (mean age 28.4 ± 8.6 years, 228 females). After adjustment for age, sex, and spherical equivalent, global pRNFL thinning was associated with moderate (GA = 33-36 wk, β = –4.68, P < .001), very (GA = 29-32 wk, β = –5.72, P < .001), and extreme (GA ≤ 28 wk, β = –8.69, P < .001) prematurity but not with low birth weight percentile (<25th percentile, P = .9) and ROP occurrence (P = .9) in multivariable analysis. ROP treatment was associated with increased pRNFL in the temporal sector (P = .002). Maternal smoking during pregnancy showed an association with pRNFL thinning (P = .07).
Our data indicate that the more preterm individuals are born the more pRNFL thinning occurs, whereas prenatal growth restriction and postnatal occurrence of ROP show less effects on pRNFL thickness. Furthermore, individuals with severe ROP with treatment but not lower ROP stages without treatment showed an increased temporal pRNFL thickness.
The aim of the study was a systematic evaluation of cognitive development in individuals with glutaric aciduria type 1 (GA1), a rare neurometabolic disorder, identified by newborn screening in ...Germany. This national, prospective, observational, multi-centre study includes 107 individuals with confirmed GA1 identified by newborn screening between 1999 and 2020 in Germany. Clinical status, development, and IQ were assessed using standardized tests. Impact of interventional and non-interventional parameters on cognitive outcome was evaluated. The majority of tested individuals (n = 72) showed stable IQ values with age (n = 56 with IQ test; median test age 11 years) but a significantly lower performance (median IQR IQ 87 78-98) than in general population, particularly in individuals with a biochemical high excreter phenotype (84 75-96) compared to the low excreter group (98 92-105; p = 0.0164). For all patients, IQ results were homogenous on subscale levels. Sex, clinical motor phenotype and quality of metabolic treatment had no impact on cognitive functions. Long-term neurologic outcome in GA1 involves both motor and cognitive functions. The biochemical high excreter phenotype is the major risk factor for cognitive impairment while cognitive functions do not appear to be impacted by current therapy and striatal damage. These findings implicate the necessity of new treatment concepts.
