Management of Delayed Suprachoroidal Hemorrhage after Glaucoma Surgery. Semin Ophthalmol 2017;:1-5.
AbstractPURPOSE: To review the most current treatment recommendations and outcomes for delayed suprachoroidal hemorrhages. METHODS: Article review of management and outcomes of suprachoroidal hemorrhages, with emphasis on delayed suprachoroidal hemorrhages in the setting of glaucoma surgery. CONCLUSION: Time of drainage of suprachoroidal hemorrhages remains controversial. Earlier drainage should be considered with high intraocular pressure, expulsion of intraocular content, or retinal detachment. In clinically stable eyes with suprachoroidal hemorrhage, recommendations range from observation to immediate drainage. Clot lysis occurs at roughly 14 days.

Optic Nerve Head Characteristics in Chronic Angle Closure Glaucoma Detected by Swept-Source OCT. Curr Eye Res 2017;42(11):1450-1457.
AbstractPURPOSE: To compare structural features in prelaminar and laminar tissues of the optic nerve head (ONH) in chronic angle closure glaucoma (CACG), primary open angle glaucoma (POAG), and control subjects. MATERIALS AND METHODS: ONH imaging was performed using swept-source optical coherence tomography (SS-OCT) for measurements of minimum rim width at Bruch's membrane opening (BMO-MRW), horizontal, and vertical lamina cribrosa depth (LCD). Prelaminar defects, categorized as hole and wedge, and lamina cribrosa (LC) defects were identified. Enhanced depth imaging spectral domain OCT (EDI-OCT) customized to perform high-resolution volume scans was used in conjunction to further characterize prelaminar holes. One eye per subject was analyzed. RESULTS: Eighty subjects (20 CACG, 40 POAG, and 20 controls) were included in the study. CACG and POAG groups had similar mean deviation on Humphrey visual field testing (-6.9 ± 5.1 vs. -6.3 ± 6.0 dB, p > 0.05) and IOP on the day of imaging (14.0 ± 3.1 vs. 13.8 ± 2.7 mmHg, p > 0.05). Thinnest and global BMO-MRW in CACG (120.3 ± 44.8, 225.5 ± 53.9 μm) and POAG (109.7 ± 56.3, 213.8 ± 59.7 μm) groups were lower than controls (200.1 ± 40.8, 308.3 ± 70.8 μm; p < 0.001 for both). Prelaminar holes were most frequent in CACG (65.0%) than POAG (25.0%, p=0.008) or control groups (20.0%, p=0.01). After adjusting for demographic and ophthalmic covariates, CACG was associated with increased odds of having prelaminar holes compared to POAG (odds ratio, 9.79; 95% CI, 2.12-45.19; p=0.003). Hole volume was similar between CACG and POAG (p > 0.05), but the CACG group had more holes per scan than POAG (maximum 2.5 ± 1.9 vs. 1.2 ± 0.4, p=0.02). Prelaminar wedge defects were less common in the CACG than the POAG group (5.0% vs. 37.5%, p=0.02). The CACG group did not differ from controls in laminar characteristics, such as LCD and LC defects. CONCLUSIONS: SS-OCT evaluation of the ONH revealed more frequent prelaminar holes in CACG compared to POAG and control patients.
