在正常眼压性青光眼（“低眼压性”青光眼）中，33只眼中有21只眼（64%）有视乳头周围脉络膜巩膜新月体或光晕，而高眼压性青光眼38只眼中有13只眼（34%）。正常眼压性青光眼的脉络膜和巩膜裸露的平均面积（5.8任意单位面积）大于高眼压性青光眼（1.4单位面积）。近视眼在正常眼压青光眼组中普遍存在。当超过4屈光度（D）的近视眼从分析中排除时，脉络膜巩膜新月体和晕轮的患病率和大小的差异仍然存在。因此，新月体的存在与椎间盘损伤相关，但还需要进一步的研究来确定这种相关性是否代表伴随着昏迷性神经萎缩的视乳头周围萎缩，或者代表着先前存在视乳头周围异常的椎间盘更易受影响。
In normal-tension glaucoma (“low-tension” glaucoma), 21 of 33 eyes (64%) had a peripapillary chorioscleral crescent or halo, compared with 13 of 38 eyes (34%) with ocular hypertension. The average area of bared choroid and sclera was greater in normal-tension glaucoma (5.8 arbitrary units of area) than in ocular hypertension (1.4 units). Myopic eyes were prevalent among the normal-tension glaucoma group. When eyes with more than 4 diopters (D) of myopia were exluded from the analysis, the difference in prevalence and size of chorioscleral crescents and halos remained. Thus, the presence of a crescent correlates with disc damage, but further work is needed to determine if the correlation represents peripapillary atrophy that accompanies glaucomatous nerve atrophy or represents a greater susceptibility of discs with preexisting peripapillary abnormality.
