Ando T, Terashima H, Yoshida H, Ueda E, Ochiai S, Fukuchi T. Relationship between long-term visual function and the ratio of foveal avascular zone area in eyes with macular hole and healthy fellow eyes. Graefes Arch Clin Exp Ophthalmol 2024:10.1007/s00417-024-06433-w. [PMID: 38446202 DOI: 10.1007/s00417-024-06433-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 02/17/2024] [Accepted: 02/27/2024] [Indexed: 03/07/2024] Open
Abstract
PURPOSE This study is to investigate the relationship between long-term changes in the foveal avascular zone (FAZ) and visual function of eyes with macular hole (MH) and compare the relationship between the FAZ of MH eyes and fellow eyes. METHODS This study included 31 patients with unilateral MH who underwent vitrectomy and their fellow eyes. Best-corrected visual acuity (BCVA) and metamorphopsia were measured preoperatively and at 1, 3, 6, and 12 months postoperatively. We evaluated retinal parameters using optical coherence tomography (OCT) and the superficial FAZ using OCT angiography. The FAZ ratio was defined as follows: (preoperative FAZ area of the MH eye)/(FAZ area of the fellow eye). RESULTS The preoperative FAZ area of MH eyes was 0.42 ± 0.08 mm2, which decreased to 0.24 ± 0.07 mm2 1 month postoperatively (p < 0.001) and slightly increased to 0.25 ± 0.06 mm2 12 months postoperatively (p = 1.000). The FAZ area did not differ significantly from that of fellow eyes (0.39 ± 0.06 mm2, p = 0.281). The FAZ area of MH eyes was not associated with visual function at any time point. The FAZ ratio showed a correlation with the preoperative, 6-month, and 12-month BCVA (r = 0.604, p < 0.001; r = 0.510, p = 0.003; and r = 0.475, p = 0.007, respectively). CONCLUSIONS A larger FAZ in the MH eye than that in the fellow eye is associated with poorer long-term visual acuity. The preoperative comparison of the FAZ of the MH eye with that of the fellow eye may be a biomarker for predicting long-term visual acuity.

Foveal morphology of normal fellow eyes of patients with unilateral macular hole. Ophthalmol Retina 2022; 6:361-368. [PMID: 34999016 DOI: 10.1016/j.oret.2021.12.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 12/22/2021] [Accepted: 12/29/2021] [Indexed: 11/21/2022]
Abstract
PURPOSE To determine the morphology of the fovea in the ophthalmoscopically and tomographically normal fellow eyes of patients with unilateral idiopathic macular hole (MH) and to determine the association between the foveal morphological parameters and the foveal outer nuclear layer (ONL) thickness. DESIGN Retrospective observational study. PARTICIPANTS Two hundred three normal fellow eyes of patients with unilateral MH and 216 normal eyes of 216 healthy subjects. METHODS All eyes were examined by swept source optical coherence tomography (OCT). The built-in software measured the average retinal and choroidal thickness in the center and in the inner four subfields defined in the Early Treatment Diabetic Retinopathy Study. The total retinal thickness and the three retinal layers at the fovea and parafovea (0.25- and 0.5-mm nasal and temporal from fovea) and foveal floor width (FFW) were measured in the image of a horizontal scan passing through the center of the fovea. We defined the thickness between the internal limiting membrane and outer plexiform layer as the inner retinal thickness, and the thickness between the external limiting membrane and retinal pigment epithelium as the outer retinal thickness. Multiple regression analyses were performed with the age, sex, axial length, and the presence of a posterior vitreous detachment as the dependent variables. MAIN OUTCOME MEASURES OCT measurements and correlations between the foveal parameters and foveal ONL thickness. RESULTS The fellow eyes had a thinner central retinal subfield, thinner fovea, thinner ONL at all points except 0.5 mm nasal, significantly thicker outer retina at all points, and a wider FFW (P=.040 to P<.0001). The foveal ONL thickness was significantly and positively correlated with the central subfield retinal thickness and foveal thickness and negatively with the FFW (all P< .0001). CONCLUSIONS The thinner and deeper fovea and the thinner ONL of the fellow eyes of patients with a unilateral MH makes these eyes more susceptible to forming MH.

Abstract
PURPOSE To present a new technique, macular hole hydrodissection, that increases the likelihood of closure for challenging macular holes (MHs) with multiple risk factors. METHODS A retrospective review of all consecutive eyes with idiopathic Stage 3 and 4 MHs that were either persistent (failed previous vitrectomy surgery), chronic (symptoms of central vision loss of ≥2 years or a clinical diagnosis for ≥1 year), and/or large (aperture diameter of ≥400 μm), having undergone the macular hole hydrodissection surgical technique between January 1, 2014, and May 1, 2017, from an institutional practice setting was conducted. This technique lyses retina-retinal pigment epithelium adhesions by injecting fluid into the MH and allows for successful closure as the mobile edges are then brought closer together. RESULTS Thirty-nine eyes of 39 patients with mean MH aperture and base diameters of 549.1 ± 159.47 μm and 941.97 ± 344.14 were included. Complete anatomical closure was achieved in 87.2% (34/39) of MHs. Vision improvement was observed in 94.9% (37/39) and gain of ≥2 lines was achieved in 79.5% (31/39). Of the MHs that achieved anatomical success, 100% (34/34) had a Type 1 closure. The mean postoperative follow-up was 320.33 ± 269.04 days. CONCLUSION The macular hole hydrodissection surgical technique improves anatomical and functional outcomes of persistent, chronic, and/or large MHs.

Changes in the size of the foveal avascular zone after vitrectomy with internal limiting membrane peeling for a macular hole. Jpn J Ophthalmol 2017; 61:465-471.

Abstract
PURPOSE To determine the size of the foveal avascular zone (FAZ) before and after vitrectomy for a macular hole (MH). STUDY DESIGN Retrospective case series study. METHODS Twenty-five eyes of 25 patients with a unilateral MH that had undergone vitrectomy with internal limiting membrane peeling were studied. The unaffected 17 fellow eyes were studied in the same way. En face images of the parafoveal region were obtained by optical coherence tomography angiography, and the images were used to measure the FAZ before and 1 month after the vitrectomy. The relationships between the different FAZ sizes and the ocular parameters were determined by Pearson product moment correlation analysis. RESULTS Compared with the preoperative superficial FAZ (sFAZ), the postoperative sFAZ was significantly reduced (P < 0.001). The postoperative sFAZ was significantly smaller than that of the fellow eye (P < 0.001). The size of the postoperative sFAZ was significantly correlated with that of the preoperative sFAZ, the postoperative foveal thickness (FT), and the sFAZ of the fellow eyes (r = 0.520, P = 0.008; r = -0.515, P = 0.012; and r = 0.702, P = 0.002, respectively). The size of the postoperative deep FAZ (dFAZ) was significantly correlated with the postoperative FT and the dFAZ of the fellow eyes (r = -0.441, P = 0.035; and r = 0.499, P = 0.049, respectively). However, no significant correlation was found between the size of the postoperative FAZ and the size of the preoperative MH. CONCLUSIONS MH closure leads to a significant decrease in the size of the FAZ symmetrical to the size of the fellow eye. The size of the postoperative FAZ is influenced by the postoperative FT independently of the size of the MH.

Abstract
PURPOSE To determine the size of the superficial foveal avascular zone (FAZ) by optical coherence tomography angiography before and after surgery for an idiopathic macular hole. METHODS A retrospective, observational case series, in which 16 eyes of 16 patients with an idiopathic macular hole were studied. Pars plana vitrectomy was performed with internal limiting membrane peeling. The foveal retinal vasculature was examined by optical coherence tomography angiography, and the area of the superficial FAZ was determined before, and at 1 and 3 months after the surgery. The area of the macular hole was also measured in the en face optical coherence tomography images. The central foveal thickness was measured to determine the relationship between the size of the superficial FAZ and foveal shape. The unaffected fellow eyes were used as controls. RESULTS The mean age of the patients was 68.9 years. The average preoperative superficial FAZ area was 0.45 ± 0.14 mm, which was significantly reduced to 0.23 ± 0.08 mm at 1 month (P < 0.001) and 0.25 ± 0.08 mm at 3 months postoperatively (P < 0.001). The size was smaller than that of the control eyes (0.36 ± 0.12 mm, P = 0.003). There was a significant inverse correlation between the area of the postoperative superficial FAZ and the central foveal thickness (r = -0.589, P = 0.016). The correlations between the visual acuity and the area of the superficial FAZ at 1 and 3 months postoperatively were not significant (P = 0.369 and 0.285). CONCLUSION The significant decrease in the superficial FAZ after the macular hole surgery indicates that there was a centripetal movement of the foveal tissue postoperatively.

Wider retinal artery trajectories in eyes with macular hole than in fellow eyes of patients with unilateral idiopathic macular hole. PLoS One 2015; 10:e0122876. [PMID: 25867212 PMCID: PMC4395100 DOI: 10.1371/journal.pone.0122876] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2014] [Accepted: 02/24/2015] [Indexed: 11/18/2022] Open
Abstract
Purpose To determine whether the width of the retinal artery (RA) trajectory was associated with the presence of a macular hole (MH). Methods A retrospective cross sectional case-control study was performed. The fundus photographs were rotated 90 degrees, and the coordinates of the best fit curve of the RA trajectory were determined automatically based on these plots using the ImageJ program. The converted coordinates were fit to a second degree polynomial (ax2/100 + bx + c) equation. The width and steepness of the RA trajectory, “a”, of the eyes with a MH eye were compared to that of the fellow eyes. Results One hundred and ten eyes of 55 consecutive patients (30 women) with a unilateral MH and healthy fellow eyes were analyzed. The mean age was 64.9 years (range 47-81 years). The constant ‘a’ was significantly smaller in eyes with a MH than that of the fellow eyes (0.379 ± 0.094 vs 0.416 ± 0.121, P = 0.001, paired t test), indicating that the RA trajectory was wider in the MH eyes than in the fellow eyes. There was a significant correlation between the axial length and ‘a’ of the RA trajectory in the MH eyes (R = 0.273, P = 0.044) and in the fellow eyes (R = 0.356, P = 0.008; Spearman’s rank correlation coefficient). Conclusions Because eyes with a MH have a significantly wider and flatter RA trajectory, there may be greater traction on the fovea which is located between the RA arches. The causative role of this finding is still unclear.
