PURPOSE To investigate the tear meniscus (TM) in medically controlled glaucoma patients (MCGP) using Anterior Segment-Optical Coherence Tomography (AS-OCT). METHODS Fifty-six MCGP, twenty-four patients with evaporative dry eye (EDE), and thirty healthy subjects (Controls), were enrolled. MCGP were divided into Group 1 (14 eyes) ß-blockers; Group 2 (14 eyes) prostaglandin analogs; Group 3 (28 eyes) ≥2 drugs. Ocular Surface Disease Index (OSDI) questionnaire, tear film break-up time (TBUT), corneal fluorescein staining (CFS), Schirmer Test I (STI), and tear meniscus height (lower and upper L-TMH, U-TMH) and area (L-TMA, U-TMA) using AS-OCT, were performed. RESULTS OSDI score was higher (P less then 0.05) in EDE and Group 3 compared Groups 1, 2 and Controls. No significant differences were found between Group 3 and EDE for all clinical parameters. L-TMA was significantly lower in Groups 1-3 (P less then 0.05) and EDE (P less then 0.001) compared to Controls, and lower in Group 3 and EDE compared to Groups 1 and 2 (P less then 0.05). L-TMH was lower in Groups 1-3 and EDE compared to Controls (P less then 0.001), and in EDE and Group 3 compared to Groups 1 and 2 (P less then 0.05). U-TMA was lower in EDE and MCGP Groups compared to controls (P less then 0.05). L-TMA and L-TMH negatively correlated with OSDI score (P less then 0.01, r=-0.379; and P less then 0.01, r=-0.352, respectively). selleck chemicals llc CONCLUSIONS AS-OCT permits a non-invasive and reliable tear meniscus imaging in medically controlled glaucoma, depicting the glaucoma-related-OSD (GR-OSD) as a dry eye disease-like condition. Thus, reduced values of tear meniscus height and area can be proposed as structural indicators of glaucoma therapy-related ocular surface disease.PRECIS Pseudoexfoliation glaucoma eyes had a similar level of peripapillary and superficial macular vessel densities compared with primary open-angle glaucoma eyes matched for age and glaucoma severity when assessed by optical coherence tomography angiography. PURPOSE To compare vessel density (VD) measured by optical coherence tomography angiography (OCT-A) between primary open-angle glaucoma (POAG) and pseudoexfoliation glaucoma (PXG) in the peripapillary and macular areas. METHODS The circumpapillary (cpVD), parafoveal (pfVD), and perifoveal vessel densities (perifVD) were obtained using OCT-A (AngioVue/RTVue-XR) in 98 eyes from 98 subjects (age, visual acuity (VA), visual field (VF) mean deviation (MD) matched 49 POAG and 49 PXG eyes). Global and 8 sectoral VDs in the peripapillary capillary layer were compared. In the macula, the superficial and deep layers of the pfVD and perifVD were analyzed globally and in 4 quadrants. Uni- and multivariate linear regression models were built using cpVD, pfVD, and perifVD as dependent variables and covariates (age, intraocular pressure [IOP], axial length [AL], signal strength index [SSI] and retinal nerve fiber layer [RNFL] thickness) were considered independent variables. RESULTS In the peripapillary region, none of the VDs differed between groups both before and after adjustment. When we adjusted superficial and deep layer macular VDs for age, IOP, SSI, AL, and RNFL thickness, all of which could affect measurements, the two groups did not differ in any sector. The cpVD in POAG eyes significantly correlated with VF MD and RNFL thickness, while IOP, VF MD, and RNFL thickness affected cpVD in PXG. The macular VD in the deep layer was associated with only SSI in both groups. CONCLUSIONS Age- and glaucoma severity-matched PXG and POAG did not significantly differ in cpVD or in most of the superficial macular VD parameters.Appendicitis is the most common reason for which pediatric patients require emergent surgery. Although surgical removal of the appendix is the standard of care for appendicitis, neutropenic patients require special consideration as optimal management for these patients remains controversial. We present a case series of 3 neutropenic
