Macular Hole During Diabetic Vitrectomy

Intraoperative FTMHs most likely occur after vitrectomy for myopic traction maculopathy (Ho et al., Retina 34(9):1833–1840, 2014; Lin and Yang, Graefes Arch Clin Exp Ophthalmol 260(2):489–496, 2022). The DV for FVP may be another condition predisposing the eye to MH during surgery. Most previous studies focused on preexisting FTMHs in PDR patients before surgery (Lai and Yang, Taiwan J Ophthalmol 5(2):85–89, 2015; Tsui et al., Sci Rep 11(1):23839, 2021; Shukla et al., Eye (Lond) 20(12):1386–1388, 2006; Mason et al., Ophthalmic Surg Lasers Imaging 39(4):288–293, 2008; Yeh et al., Retina 29(3):355–361, 2009; Chen and Yang, J Ophthalmol 2018:3470731, 2018; Karimov et al., Clin Ophthalmol 14:4125–4133, 2020; Babu et al., Indian J Ophthalmol 69(11):3302–3307, 2021; Kumar et al., BMJ Case Rep 14(2):e240730, 2021). A literature search revealed no previous research describing the characteristics and treatment of FTMHs created during vitrectomy for PDR. Because an unsealed MH may significantly affect visual function and MH may lead to retinal detachment in postoperative eyes with PDR if traction release has not been thorough enough, it is important to investigate the clinical features, management, and prognosis of FTMHs created during surgery for PDR.
