The effect of vitreopapillary adhesion (VPA) in macular diseases is not understood. Spectral-domain optical coherence tomography/scanning laser ophthalmoscopy (SD-OCT/SLO) was used to identify VPA in macular holes, lamellar holes, macular pucker, and dry age-related macular degeneration (AMD).
Ultrasonography and SD-OCT/SLO were performed in 99 subjects: 17 with macular holes, 11 with lamellar holes, 28 with macular pucker, 15 with dry AMD, and 28 age-matched controls. Outcome measures were the presence of total posterior vitreous detachment (PVD) by ultrasound and the presence or absence of VPA and intraretinal cystoid spaces by SD-OCT/SLO.
PVD was detected by ultrasound in 26 (92.9%) of 28 eyes with macular pucker, 6 (54.5%) of 11 eyes with lamellar holes (P = .01), and 4 (23.5%) of 17 eyes with macular holes (P = .000003). SD-OCT/SLO detected VPA in 15 (88.2%) of 17 eyes with macular holes, 11 (39.3%) of 28 age-matched controls (P = .002), 4 (36.4%) of 11 eyes with lamellar holes (P = .01), 4 (26.7%) of 15 eyes with dry AMD (P = .0008), and 5 (17.9%) of 28 eyes with macular pucker (P = .000005). Intraretinal cystoid spaces were present in 15 (100%) of 15 eyes with macular holes with VPA. In eyes with macular pucker, 4 (80%) of 5 with VPA had intraretinal cystoid spaces, but only 1 (4.3%) of 23 without VPA had intraretinal cystoid spaces (P = .001).
VPA was significantly more common in eyes with macular holes than in controls or eyes with dry AMD, lamellar holes, or macular pucker. Intraretinal cystoid spaces were found in all eyes with macular holes with VPA. When present in macular pucker, VPA was frequently associated with intraretinal cystoid spaces. Although these investigations do not study causation directly, VPA may have an important influence on the vectors of force at the vitreoretinal interface inducing cystoid spaces and holes.
玻璃体视乳头粘连(VPA)在黄斑疾病中的作用尚不清楚。本研究采用频域光学相干断层扫描/扫描激光检眼镜(SD-OCT/SLO)来识别黄斑裂孔、板层裂孔、黄斑皱襞和干性年龄相关性黄斑变性(AMD)中的VPA。
对99例受试者进行了超声检查和SD-OCT/SLO检查,其中17例患有黄斑裂孔,11例患有板层裂孔,28例患有黄斑皱襞,15例患有干性AMD,28例为年龄匹配的对照组。观察指标包括超声检查显示的完全性玻璃体后脱离(PVD)情况,以及SD-OCT/SLO检查显示的VPA和视网膜内囊样腔隙情况。
超声检查发现,28例黄斑皱襞患者中有26例(92.9%)存在PVD,11例板层裂孔患者中有6例(54.5%)存在PVD(P = 0.01),17例黄斑裂孔患者中有4例(23.5%)存在PVD(P = 0.000003)。SD-OCT/SLO检查发现,17例黄斑裂孔患者中有15例(88.2%)存在VPA,28例年龄匹配的对照组中有11例(39.3%)存在VPA(P = 0.002),11例板层裂孔患者中有4例(36.4%)存在VPA(P = 0.01),15例干性AMD患者中有4例(26.7%)存在VPA(P = 0.0008),28例黄斑皱襞患者中有5例(17.9%)存在VPA(P = 0.000005)。15例存在VPA的黄斑裂孔患者中,所有15例(100%)均有视网膜内囊样腔隙。在黄斑皱襞患者中,5例存在VPA的患者中有4例(80%)有视网膜内囊样腔隙,而23例不存在VPA的患者中只有1例(4.3%)有视网膜内囊样腔隙(P = 0.001)。
黄斑裂孔患者中VPA的发生率明显高于对照组或干性AMD、板层裂孔或黄斑皱襞患者。所有存在VPA的黄斑裂孔患者均发现有视网膜内囊样腔隙。当VPA存在于黄斑皱襞时,常与视网膜内囊样腔隙相关。虽然这些研究未直接探讨因果关系,但VPA可能对玻璃体视网膜界面的力向量有重要影响,从而导致囊样腔隙和裂孔的形成。
