“…This is longer than previous studies. [16][17][18][19][20][21][22][23][24][25] It has been reported that the IMHs with disease course more than 6 months is more di cult to close than that of less than 6 months. 11 Therefore, we did a subgroup analysis for those patients with a disease course longer than 6 months.…”

“…These parameters are also complex and di cult to calculate, limited their application values in busy real world clinical practice. [16][17][18][19] Based on our clinical experiences 11,20,[23][24][25][26] , we feel that the preoperative MH morphological characteristics are different between postoperative closed and unclosed stage III or IV IMHs. Thus we try to nd a method to quantitatively evaluate the morphological characteristics of preoperative MHs to predict the postoperative closure for stage III or IV IMHs.…”

“…Better surgical and functional results are associated with earlier disease stage, better preoperative visual acuity (VA), shorter duration of symptoms, younger patient age, vertical metamorphopsia and the experience of the surgeon. [16][17][18][19][20][21][22][23][24][25][26] With the further understanding of IMH, more factors have been found to predict the closure of IMHs.…”

Purpose: To determine whether preoperative hole diameter ratio (HDR) is a predictive factor for postoperative anatomical outome for stage III or IV idiopathic macular holes (IMHs).Methods: One-hundred and one eyes with stage III or IV IMH were included in this retrospective case series study. All cases were treated with vitrectomy combined with internal limiting membrane (ILM) peeling and room air tamponade. The macular hole (MH) minimum and maximum diameter was measured on preoperative optical coherence tomography (OCT) images. The HDR was defined as the minimum to maximum diameter ratio. Results: Eighty-one eyes (80.2%) got a Type I closure after surgery (group A). Postoperative unclosed MHs were found in 20 eyes (19.8%) (group B). The preoperative minimal diameter (703.6±116.1mm vs. 597.6±120.1mm, P<0.01) and HDR (0.6±0.1 vs. 0.5±0.1, P=0.01) were both significantly smaller in postoperative closed eyes. The closure rate of IMHs with HDR<0.6 was significantly higher than those with HDR³0.6 (90.2% vs. 65.0%P=0.002) .Conclusions: Preoperative HDR<0.6 is predictive for a good postoperative anatomical outcome in stage III or IV IMHs.

ZusammenfassungVeränderungen im Glaskörper mit Schwächung der vitreoretinalen Adhäsion und Verflüssigung des Glaskörpers führen im Normalfall zu einer Abhebung der Glaskörpergrenzmembran von der Membrana limitans interna. Geschieht dies nicht simultan und komplett oder mit vorheriger Bildung prämakulärer Verdichtungen, können je nach Aufspaltung der hinteren Glaskörpergrenzmembran bzw. bei nur partieller Abhebung verschiedene Veränderungen entstehen, wie eine vitreomakuläre Traktion, eine epiretinale Membran oder ein Makulaforamen.

“…Other important variables are volume, areas, diameters and height. These measures are important to assess if it is possible the hole closure [12][13][14]. The identification of MH in OCT images can be made through the top boundaries of the internal limiting membrane (ILM) and the retinal pigment epithelium (RPE) [15][16][17].…”

Macular holes are a blinding condition that occur due to overuse of the fovea, in which a hole alters the natural retinal structure. Optical Coherence Tomography (OCT) is a way of mapping and shaping retinal sections without physical contact and has become a powerful tool for diagnosing pathologies. This paper deals with a review of automated segmentation of macular holes in OCT images, detailing its varied possibilities. It may be considered something new, no reviews were made about the topic. The purpose of this review is to show the latest trends, through the approaches in preprocessing and segmentation. Recent studies were used to validate the research, 2011 onwards, from the Science Direct, IEEE, PubMed and Google scholar bases. The objectives, methodology, tools, database, advantages, disadvantages, validation metrics and results of the selected material are analyzed and mentioned. Based on this, techniques and their results are compared. From this, future outlook scenarios of automated segmentation of macular holes in OCT images are mentioned.

Role of macular hole angle in macular hole closure

Abstract: Our study shows no significant correlation between macular hole angle and hole closure. Minimum diameter between the edges and longest diameter of the hole are best predictors of hole closure and postoperative VA.
