Investigation of the Peripapillary Choriocapillaris in Normal Tension Glaucoma, Primary Open-angle Glaucoma, and Control Eyes.

Precis: The peripapillary choriocapillaris (CC) was observed to be significantly impaired in normal tension glaucoma (NTG) subjects compared with normal controls using optical coherence tomography angiography (OCTA).

Purpose: The aim was to quantitatively evaluate the peripapillary CC in NTG, primary open-angle glaucoma (POAG), and control eyes using OCTA.

Materials And Methods: Ninety eyes (30 controls, 30 NTG, and 30 POAG) from 73 patients were imaged using the Zeiss Plex Elite 9000.

Epigenetics of dominance for enzyme activity.

We have isolated and purified two parental homodimers and a unique heterodimer of acid phosphatase [coded by Acph-1 (1.05)(F) and Acph-1 (0.95)(S)] from isogenic homozygotes and heterozygotes of Drosophila malerkotliana.
