Literature review and meta-analysis of translaminar pressure difference in open-angle glaucoma
There is increasing evidence in the literature regarding translaminar pressure difference's (TPD) role in the pathophysiology of glaucoma. The optic nerve is exposed not only to intraocular pressure in the eye, but also to intracranial pressure (ICP), as it is surrounded by cerebrospinal fluid in the subarachnoid space. Although pilot studies have identified the potential importance of TPD in glaucoma, limited available data currently prevent a comprehensive description of the role that TPD may have in glaucomatous pathophysiology. In this review, we present all available qualified data from a systematic review of the literature of the role of TPD in open-angle glaucoma (OAG). PubMed (Medline), OVID Medline, ScienceDirect, SpringerLink, and all available library databases were reviewed and subsequent meta-analysis of pooled mean differences are presented where appropriate. Five papers including 396 patients met criteria for inclusion to the analysis. Importantly, we included all observational studies despite differences in ICP measurement methods, as there is no consensus regarding best-practice ICP measurements in glaucoma. Our results show that not only TPD is higher in glaucoma patients compared with healthy subjects, it is related to structural glaucomatous changes of the optic disc. Our analysis suggests further longitudinal prospective studies are needed to investigate the influence of TPD in OAG, with a goal of overcoming methodological weaknesses of previous studies
Long-term outcomes of prostaglandin analog versus timolol maleate in ocular hypertensive or primary open-angle glaucoma patients in Europe
Use of colour Doppler imaging in ocular blood flow research
The main objective of this report is to encourage consistent quality of testing and reporting within and between centres that use colour Doppler imaging (CDI) for assessment of retrobulbar blood flow. The intention of this review is to standardize methods in CDI assessment that are used widely, but not to exclude other approaches or additional tests that individual laboratories may choose or continue to use.status: publishe

Referral for first glaucoma surgery in Europe, the ReF-GS study
PURPOSE: To analyze the appropriateness of referrals for incisional glaucoma-surgery in Europe. METHODS: Referrals for the first open-angle glaucoma surgery between January and October 2017 were analyzed in 18 countries: 8 "old" European Union, 7 "new" European Union and 3 non-European Union European countries. RESULTS: Most eyes had primary open-angle or exfoliative glaucoma. The average mean deviation was -13.8âdB with split fixation in 44.3%. No structural progression analysis was made before the referrals. The most common medications were the combination of a prostaglandin analog, timolol and a carbonic anhydrase inhibitor (30.0%), and all other combinations comprisingââ©Ÿâ3 molecules (33.8%). Laser trabeculoplasty was reported in only 18.4%. Of the 294 referrals, 41.5% were appropriate and timely, 35.0% appropriate but later than optimal, and 17.6% appropriate but too late (minimal vision maintained). The treatment period was significantly longer (median: 7âyears) in the "old" European Union countries than in the other groups (3 and 2âyears, respectively). No between-group differences were seen in intraocular pressure and mean deviation, but the non-European Union group referred the patients at significantly lower cup/disk ratio and eye drop usage than the other groups. Split fixation was significantly more common in the "old" (60.6%) than the "new" European Union countries (38.7%), and in both EU country-groups than in the non-European Union countries (13.6%). CONCLUSIONS: Of 294 European open-angle glaucoma referrals for first glaucoma-surgery, 41.5% were completely satisfactory. The damage was typically advanced, and the care varied considerably among the countries. This suggests that further efforts are necessary to improve glaucoma care in Europe.status: publishe
