Purpose
To report two cases of thyroid eye disease (TED) associated compressive optic neuropathy (CON) that resolved after treatment with teprotumumab.
Observation
Two patients presented with active TED resulting in mild CON with the typical corresponding visual field (VF) defects. Both patients were initiated on intravenous (IV) corticosteroid therapy but despite treatment had persistent VF defects. Both patients were then treated with teprotumumab and demonstrated marked clinical improvement and complete resolution of TED-CON VF defects early in their infusion course.
Conclusions and importance
These cases suggest that teprotumumab can be a rapid and effective treatment for TED-CON, and raises the question of whether it may be superior to IV corticosteroid therapy.
Purpose:
To assess optic nerve head (ONH) and peripapillary microvasculature in primary open-angle glaucoma (POAG) of mild to moderate severity using swept-source optical coherence tomography angiography (OCTA).
Materials and Methods:
In a cross-sectional study, swept-source OCTA images were analyzed for 1 eye from each of 30 POAG patients with glaucomatous Humphrey visual field loss and 16 controls. The anatomic boundary of ONH was manually delineated based on Bruch’s membrane opening and large vessels were removed from en face angiography images to measure vessel density (VD) and the integrated OCTA by ratio analysis signal (IOS), suggestive of flow, in the ONH and peripapillary region. POAG subgroup analysis was performed based on a history of disc hemorrhage (DH) matched by visual field mean deviation (MD).
Results:
POAG (mean MD ± SD, −3.3 ± 3.0 dB) and control groups had similar demographic characteristics and intraocular pressure on the day of imaging. Groups did not differ in superficial ONH VD or flow indicated by IOS (P ≥ 0.28). POAG eyes showed significantly lower VD (39.4% ± 4.0%) and flow (38.8% ± 5.6%) in deep ONH, peripapillary VD (37.9% ± 2.9%) and flow (43.6% ± 4.0%) compared with control eyes (44.1% ± 5.1%, 44.7% ± 6.9%, 40.7% ± 1.7%, 47.8% ± 2.5%, respectively; P ≤ 0.007 for all). In the subgroup analysis, POAG eyes with (n = 14) and without DH (n = 16) had similar measured OCTA parameters (P > 0.99 for all).
Conclusions:
The image processing methodology based on the anatomic boundary of ONH demonstrated compromised microvasculature in the deep ONH and peripapillary region in eyes with mild to moderate POAG, regardless of the history of DH.
Purpose: To determine the clinical relevance of prelaminar wedge defects (PLWDs) detected by sweptsource optical coherence tomography (SS-OCT) in primary open-angle glaucoma (POAG). Materials and Methods: In this retrospective case-control study, PLWDs were defined as triangularshaped defects at the surface of the optic nerve prelaminar tissue, not adjacent to blood vessels, present on cross-sectional SS-OCT scans. Two observers masked to diagnosis independently reviewed scans to detect PLWDs and lamina cribrosa defects. History of disc hemorrhage, occurring within 2 years prior to imaging, was obtained from chart review. One eye per subject was randomly selected. Two-sided t-tests, analysis of variance with Bonferroni correction, and multivariable logistic regression analysis were performed to explore demographic and clinical features associated with PLWDs. Results: 40 POAG and 23 control eyes were included. PLWDS were found in 27.5% of POAG (n = 11) and 4.3% of controls (n = 1, p = .04). Eyes with repeat SS-OCT imaging (7 POAG and 0 controls) had persistent PLWDs. More POAG eyes with PLWDs had a history of disc hemorrhage (45.5%) than POAG eyes without PLWDs (3.4%, p = .004). On multivariable analysis, compared to POAG without PLWDs, POAG with PLWDs had increased odds of observed disc hemorrhage (OR = 21.6, 95% CI, 2.2-589.0, p = .02) after adjusting for age, gender, visual field mean deviation and maximum intraocular pressure (IOP). POAG with PLWDs had more lamina cribrosa defects (45.5%) than POAG without PLWDs (3.4%, p = .01) but did not differ significantly from controls (8.7%, p = .07). Compared to all patients without PLWDs, patients with PLWDs had increased odds of having lamina cribrosa defects (OR = 44.8; 95% CI, 6.3-703.6, p < .001) after adjusting for age, gender, and maximum IOP. Conclusions: PLWDs were more frequently found in POAG than control eyes and were associated with a history of disc hemorrhage and lamina cribrosa defects. PLWDs may be a useful imaging biomarker of glaucomatous damage.
In the study region, mycobacteriosis most affected adult males with low schooling. Most patients presented comorbidities in particular co-infection with the HIV virus. M. avium is the most prevalent species in the region with the M. abscessus/M. massiliense/M. bolletii species being the main cause of nosocomial infections.
