PURPOSE
To report difference in fundus autofluorescence (FAF) results between macular hole retinal detachment (MHRD) and myopic foveoschisis (MF) in highly myopic eyes.
DESIGN
Observational case reports.
METHODS
Total of 20 highly myopic eyes were included in this study (MHRD, six eyes; MF with macular hole [MH], three eyes; MF without MH, 11 eyes). The authors observed both standard and near-infrared FAF images using the Heidelberg Retina Angiograph 2 (HRA2; Heidelberg Engineering, Heidelberg, Germany).
RESULTS
MHRD typically showed extensive hypo-FAF and foveal hyper-FAF. Hypo-FAF and hyper-FAF seemed to account for RD area and MH, respectively. Some cases of MF had almost normal results, except for a subtle mottled pattern of hyper-FAF.
CONCLUSIONS
MHRD and MF showed different patterns of FAF, and this fact could be helpful in diagnosing MHRD from MF. Hyperviscous subretinal fluid might have blocked FAF signal in MHRD, but not in MF.
目的
报告高度近视眼中黄斑裂孔性视网膜脱离（MHRD）与近视性黄斑劈裂（MF）之间的眼底自发荧光（FAF）结果差异。
设计
观察性病例报告。
方法
本研究共纳入20只高度近视眼睛（MHRD 6只眼；伴有黄斑裂孔[MH]的MF 3只眼；不伴有MH的MF 11只眼）。作者使用海德堡视网膜血管造影仪2（HRA2；德国海德堡海德堡工程公司）观察标准和近红外FAF图像。
结果
MHRD通常表现为广泛的低自发荧光和黄斑中心凹高自发荧光。低自发荧光和高自发荧光似乎分别对应视网膜脱离区域和黄斑裂孔。除了一些细微的高自发荧光斑点状图案外，部分MF病例的结果几乎正常。
结论
MHRD和MF表现出不同的FAF模式，这一事实有助于从MF中诊断MHRD。高黏滞性视网膜下液可能在MHRD中阻断了FAF信号，但在MF中未阻断。
