Little is known about the papillomacular bundle defect (PMBD) in glaucoma. As such, we investigated the frequency of PMBD in glaucoma patients with high myopia, and its risk factors. In this retrospective, cross-sectional study, Retinal nerve fiber layer (RNFL) defect was analyzed in 92 glaucomatous eyes with high myopia (axial length of 26.0 mm or more or an average spherical value of –6.0 diopters or less). After dividing them into two groups with and without PMBD, respectively, the clinical characteristics of the groups were compared and analyzed. The mean age of the patients was 52.1 ± 10.5 years, and there were 53 males and 39 females. PMBD were observed in 55 eyes (59.8%). There was no significant intergroup difference in baseline or follow-up intraocular pressure (IOP). Parapapillary atrophy (PPA)-to-Disc-area ratio (OR 3.83, CI:1.58 – 10.27), lamina cribrosa defect (LCD; OR 2.92, CI :1.14 – 8.13, p = 0.031) and central visual field defect (CVFD; OR 3.56, CI : 1.38 – 9.58, p = 0.010) were significantly associated with the PMBD group.

Purpose: To investigate changes in eye movement amplitude after conjunctival recession and conjunctivo-limbal autograft for treating recurrent pterygium with ocular motility restriction. Methods: We retrospectively analyzed 18 eyes of 16 patients who had recurrent pterygium with ocular motility restriction, who had received conjuntivo-limbal autografts from January 2011 to December 2019 and who had been followed-up for more than 6 months. We evaluated changes in eye movement amplitude, best corrected visual acuity, uncorrected visual acuity, corneal astigmatism and keratometry, and recurrence and complication rates before and after surgery. Results: The mean age of the patients was 63.9 ± 9.7 years. Eye movement amplitude increased significantly from 5.80 ± 1.70 mm preoperatively to 7.02 ± 1.37 mm postoperatively (p < 0.001). The mean UCVA increased from 0.67 ± 0.46 preoperatively to 0.36 ± 0.35 postoperatively (p < 0.001). The mean corneal astigmatism decreased from 3.51 diopters (D) preoperatively to 1.22 D postoperatively (p = 0.001). According to the power vector analysis, M and B were significantly reduced after the surgery, but the changes in J0 and J45 were not significant. No recurrence of pterygium was observed. Conclusions: Eye movement amplitude for severe recurrent pterygium with symblepharon or ocular motility restriction quantitatively measured the range of ocular movement clinically and was applied to determine the severity of recurrent pterygium and predict the surgical outcome. Conjunctivo-limbal autograft for severe recurrent pterygium is thought to be a safe and effective surgical method because it solves the ocular motility restriction caused by adhesions and has low recurrence rates, although it requires the skilled experience and techniques of the operator and a long operation time.

Purpose: To evaluate the types, frequency, and causes of complications at the donor site after conjunctivo-limbal autograft for primary or recurrent pterygium treatment. Methods: From January 2010 to December 2016, 91 eyes of 91 patients (male, n = 37; female, n = 54; mean age, 53.29 ± 10.73 years), diagnosed with primary or recurrent pterygium, and who were followed up for 6 months or longer after conjunctivo-limbal autograft, were enrolled in this study retrospectively. Results: Of the 91 eyes, 27 eyes (29.7%) developed a conjunctival scar on the donor site and 36 eyes (39.6%) had localized vascularization. Eighteen eyes (19.8%) had a conjunctival scar and localized vascularization. Conjunctival granuloma and limbal stem cell deficiency occurred in one eye (1.1%). Multiple regression analysis showed that having a conjunctival scar and localized vascularization were significantly correlated with young age (p < 0.001), but were not significantly correlated with gender, pterygium type, dry eye, conjunctivochalasis, hypertension, diabetes, anticoagulant treatment, graft size, or delayed epithelialwound healing. Conclusions: Conjunctival scarring or localized vascularization on the donor site after conjunctivo-limbal autograft for the treatment of the pterygium was found to be significantly higher in younger patients. Therefore, it is recommended that conjunctivo-limbal autograft should be adequately explained for donor-site complications in younger-aged pterygium patients.
