[PMID: 37321556 DOI: 10.1016/j.jcjo.2023.05.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 04/17/2023] [Accepted: 05/10/2023] [Indexed: 06/17/2023]
Abstract
OBJECTIVE This study investigates the association between preoperative intraretinal fluid (IRF) area and preoperative and postoperative best-corrected visual acuity (BCVA) in surgically repaired idiopathic macular holes (MH). This study further evaluates other prognostic indices related to MH repair that may assist clinicians' understanding of MH operative management. DESIGN Retrospective cohort study conducted at a single institution. PARTICIPANTS A total of 251 patients who underwent surgery for idiopathic MH between January 2012 and January 2021. METHODS Segmentation was performed on ocular coherence tomography scans of 251 eyes with MH and IRF. Associations between IRF area and preoperative and postoperative BCVA at 1, 3, and 6 months, preoperative and postoperative central subfield thickness, MH diameter, staging, closure status, and type of closure were evaluated using Spearman's correlation analysis. RESULTS Preoperative IRF area was moderately correlated with preoperative BCVA (r = -0.32; p < 0.001) and negligibly correlated with postoperative BCVA at 1, 3, and 6 months (r = -0.14, p = 0.026; r = -0.21, p < 0.001; and r = -0.19, p < 0.001, respectively). Preoperative IRF area was strongly correlated with MH minimum linear diameter (r = 0.56; p < 0.001) and MH base diameter (r = 0.65; p < 0.001). Other associations were not statistically significant. CONCLUSION Preoperative IRF area in patients with idiopathic MH demonstrated a moderate correlation with preoperative BCVA and a negligible or weak correlation with postoperative BCVA at up to 6 months, suggesting that vision may not have a clinically significant relationship with IRF in the setting of MH.

Novel Artificial Intelligence-Based Assessment of Imaging Biomarkers in Full-Thickness Macular Holes: Preliminary Data from a Pivotal Trial. J Clin Med 2024; 13:628. [PMID: 38276134 PMCID: PMC10816123 DOI: 10.3390/jcm13020628] [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: 11/07/2023] [Revised: 01/10/2024] [Accepted: 01/16/2024] [Indexed: 01/27/2024] Open
Abstract
Artificial intelligence (AI)- and deep learning (DL)-based systems have shown significant progress in the field of macular disorders, demonstrating high performance in detecting retinal fluid and assessing anatomical changes during disease progression. This study aimed to validate an AI algorithm for identifying and quantifying prognostic factors in visual recovery after macular hole (MH) surgery by analyzing major optical coherence tomography (OCT) biomarkers. This study included 20 patients who underwent vitrectomy for a full-thickness macular hole (FTMH). The mean diameter of the FTMH was measured at 285.36 ± 97.4 μm. The preoperative best-corrected visual acuity (BCVA) was 0.76 ± 0.06 logMAR, improving to 0.38 ± 0.16 postoperatively, with a statistically significant difference (p = 0.001). AI software was utilized to assess biomarkers, such as intraretinal fluid (IRF) and subretinal fluid (SRF) volume, external limiting membrane (ELM) and ellipsoid zone (EZ) integrity, and retinal hyperreflective foci (HRF). The AI analysis showed a significant decrease in IRF volume, from 0.08 ± 0.12 mm3 preoperatively to 0.01 ± 0.01 mm3 postoperatively. ELM interruption improved from 79% ± 18% to 34% ± 37% after surgery (p = 0.006), whereas EZ interruption improved from 80% ± 22% to 40% ± 36% (p = 0.007) postoperatively. Additionally, the study revealed a negative correlation between preoperative IRF volume and postoperative BCVA recovery, suggesting that greater preoperative fluid volumes may hinder visual improvement. The integrity of the ELM and EZ was found to be essential for postoperative visual acuity improvement, with their disruption negatively impacting visual recovery. The study highlights the potential of AI in quantifying OCT biomarkers for managing MHs and improving patient care.

Endo H, Kase S, Takahashi M, Ito Y, Sonoda S, Sakoguchi T, Sakamoto T, Katsuta S, Ishida S, Kase M. Changes in choriocapillaris structure occurring in idiopathic macular hole before and after vitrectomy. Graefes Arch Clin Exp Ophthalmol 2023:10.1007/s00417-023-06004-5. [PMID: 36795162 DOI: 10.1007/s00417-023-06004-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 01/16/2023] [Accepted: 02/02/2023] [Indexed: 02/17/2023] Open
Abstract
PURPOSE The aim of this study was to analyze the anatomical choroidal vascular layers and the changes in idiopathic macular hole (IMH) eyes over time after vitrectomy. METHODS This is a retrospective observational case-control study. Fifteen eyes from 15 patients who received vitrectomy for IMH and age-matched 15 eyes from 15 healthy controls were enrolled in this study. Retinal and choroidal structures were quantitatively analyzed before vitrectomy and 1 and 2 months after surgery using spectral domain-optical coherence tomography. Each choroidal vascular layer was divided into the choriocapillaris, Sattler's layer, and Haller's layer, and then, the choroidal area (CA), luminal area (LA), stromal area (SA), and central choroidal thickness (CCT) were calculated using binarization techniques. The ratio of LA to CA was defined as the L/C ratio. RESULTS The CA, LA, and L/C ratios were 36.9 ± 6.2, 23.4 ± 5.0, and 63.1 ± 7.2 in the choriocapillaris of IMH and were 47.3 ± 6.6, 38.3 ± 5.6, and 80.9 ± 4.1 in that of control eyes, respectively. Those values were significantly lower in IMH eyes than in control eyes (each P < 0.01), whereas there was no significant difference in total choroid, Sattler's layer, and Haller's layer or CCT. The ellipsoid zone defect length showed a significant negative correlation with the L/C ratio in total choroid and with CA and LA in the choriocapillaris of IMH (R = - 0.61, P < 0.05, R = - 0.77, P < 0.01, and R = - 0.71, P < 0.01, respectively). In the choriocapillaris, the LA were 23.4 ± 5.0, 27.7 ± 3.8, and 30.9 ± 4.4, and the L/C ratios were 63.1 ± 7.2, 74.3 ± 6.4, and 76.6 ± 5.4 at baseline, 1 month, and 2 months after vitrectomy, respectively. Those values showed a significant increase over time after surgery (each P < 0.05), whereas the other choroidal layers did not alter consistently with respect to changes in choroidal structure. CONCLUSIONS The current OCT-based study demonstrated that the choriocapillaris was exclusively disrupted between choroidal vascular structures in IMH, which may correlate with the ellipsoid zone defect. Furthermore, the L/C ratio of choriocapillaris recovered after IMH repair, suggesting an improved balance between supply and demand of oxygen that has collapsed due to temporary loss of central retinal function by IMH.

The effect of retinal perfusion on the bioelectric activity of the retina in full-thickness macular holes. OPHTHALMOLOGY JOURNAL 2023. [DOI: 10.17816/ov111903] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/11/2023] Open
Abstract
BACKGROUND: Information on retinal capillary perfusion in idiopathic full-thickness macular hole (FTMH) is limited, and there are no data on the possible effect of blood supply to individual areas and layers of the retina on their functional activity.
AIM: To study the relationship between vascular perfusion in the superficial and deep capillary plexuses (SCP and DCP) and the bioelectrical activity of the retina in full-thickness macular hole.
MATERIALS AND METHODS: Multifocal electroretinography (mfERG), optical coherence tomography (OCT), and OCT-angiography (OCTA) were performed in 18 eyes with FTMH and 10 intact eyes. In the projection of individual hexagons of the mfERG pattern, parameters of bioelectrical activity were compared with structural changes (hole, cystic changes), capillary density in the SCP and DCP.
RESULTS: In the FTMH group, the density of capillaries in the superficial capillary plexuses correlated with P1 implicit time in the R2 ring hexagons (R = 0.23, p 0.05), in the hole zone and intraretinal cystic changes (R = 0.21 and R = 0.22, p 0.05), P1 amplitude in the hole zone (R = 0.24, p 0.05). In deep capillary plexuses, the capillary density correlated with N1 implicit time at the fixation point and the hole zone (R = 0.57 and R = 0.19, p 0.05), P1 implicit time at the hole zone (R = 0.2, p 0.05), P1 amplitude in the hexagons of the R2 and R3 rings (R = 0.46 and R = 0.44, p 0.05), more pronounced in the hole zone and cystic changes (R = 0.54 and R = 0.29, p 0.05).
CONCLUSIONS: There is a correlation between capillary perfusion in different layers of the retina and its bioelectrical activity in FTMH. A decrease in perfusion in the deep capillary plexus of the macula with a chronic macular hole may be a predictor of a low functional prognosis in the outcome of surgical treatment of FTMH.

Abstract
In this review, we will focus on different non-invasive retinal imaging techniques that can be used to evaluate morphological and functional features in full-thickness macular holes with a prognostic purpose. Technological innovations and developments in recent years have increased the knowledge of vitreoretinal interface pathologies by identifying potential biomarkers useful for surgical outcomes prediction. Despite a successful surgery of full-thickness macular holes, the visual outcomes are often puzzling, so the study and the identification of prognostic factors is a current topic of interest. Our review aims to provide an overview of the current knowledge on prognostic biomarkers identified in full-thickness macular holes by means of different retinal imaging tools, such as optical coherence tomography, optical coherence tomography angiography, microperimetry, fundus autofluorescence, and adaptive optics.
