Our study adds important information regarding differentiating clinical and radiological features between malignant and benign epithelial lacrimal gland tumours that would aid in their management.

Background/Objectives To compare postoperative lagophthalmos after maximal levator resection (MLR) and frontalis suspension (FS) in congenital ptosis patients with poor levator function (LF). Methods A cross-sectional study was performed to compare postoperative outcomes in patients with preoperative LF ≤ 4 mm who had undergone MLR or FS at a single tertiary institution, and who had visited the outpatient clinic between February 2017 and August 2018. Main outcome measures were as follows: (1) Preoperative LF and margin reflex distance 1 (MRD1), (2) Postoperative MRD1, lagophthalmos and grade of superficial punctate keratopathy (SPK). Results Our study comprised 152 eyelids of 122 patients. There were 71 eyelids in the MLR group and 81 eyelids in the FS group. The MLR group had comparable mean postoperative MRD1 (2.8 ± 0.8 mm) to the FS with autogenous fascia lata (AFL) group (3.0 ± 0.7 mm), while the FS with preserved fascia lata (PFL) group had the lowest mean postoperative MRD1 (2.2 ± 1.0 mm). The PFL group had significantly less lagophthalmos (0.6 ± 1.0 mm) than the AFL (1.9 ± 1.4 mm) and maximal levator resection (1.9 ± 1.7 mm) groups. In the MLR group, there was no significant difference in postoperative surgical measurements between the LF 0-2 mm group and LF 2.5-4 mm group in terms of exposure keratopathy, degree of lagophthalmos and MRD1. Conclusion MLR is an effective alternative to FS in congenital ptosis patients with poor levator function, with the risk of postoperative lagophthalmos related to postoperative MRD1 rather than preoperative LF.

BackgroundTo report our findings in a patient with asteroid hyalosis (AH) who had a severe reduction of his visual acuity following cataract surgery. The vision was improved by vitreous surgery.Case presentationThe patient was an 81-year-old man. Following cataract surgery on his left eye, his decimal best-corrected visual acuity (BCVA) was markedly reduced from 0.2 to 0.02. A large number of asteroid bodies (ABs) was observed to be concentrated on the posterior surface of the implanted intraocular lens. Ultrasound B-mode images showed turbidity of the vitreous that was denser in the anterior vitreous where the ABs were concentrated. During vitrectomy, the ABs were observed to be concentrated in the anterior vitreous cavity, and a complete posterior vitreous detachment (PVD) was present. After vitrectomy successfully removed the ABs, the visibility of the fundus improved and the BCVA recovered to 1.0.ConclusionWe suggest that the visual impairment after the cataract surgery was due to the concentrated ABs in the anterior vitreous cavity. The clustering of the ABs in the anterior vitreous cavity was most likely caused by the PVD that developed during the cataract surgery.
