Exfoliation syndrome (XFS) was characterized by the abnormal deposition of the fber-like material intraocularly, and manifested as white or gray, powdery exfoliation material (XFM) on the pupillary border and (or) anterior lens capsule under slit lamp microscopy. XFM could obstruct the trabecular meshwork and cause exfoliation glaucoma (XFG). In addition, XFM that entered aqueous humor circulation could enter bloodstream and result in vascular damage. XFM could enter ocular fundus microvascular and capillary vessels, causing abnormalities of fundus structures and vessels. Optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA), which were based on optical coherence tomography technology, had the advantages of real-time, non-intrusive and high resolution, et al. OCT and OCTA were widely used in detection of fundus structural and vascular abnormalities. Tis study was to review the fundus lesion of XFS on OCT and OCTA.

The whole lacrimal passage intubation is widely used in lacrimal surgery. However, one of the most typical complications is the prolapse of the silicone tube from the medial canthus. In case, the bicanalicular silicone tube afterwhole lacrimal duct intubation has completely prolapsed from the medial canthus before extubation, then cannot be found in the opening of the nasolacrimal duct, and it would be a challenge to reposition or removal. A novel approach to employ a modified suture-probe and silk thread traction technique has been developed, and it is not only safe and effective, but also cost-effective.

The whole lacrimal passage intubation is widely used in lacrimal surgery. However, one of the most frequent complications is the prolapse of the silicone tube from the medial canthus. In cases where the bicanalicular silicone tube after whole lacrimal duct intubation has completely prolapsed from the medial canthus before the time of extubation and cannot be found in the opening of the nasolacrimal duct, repositioning or removal can pose a challenge. A novel method employing a modified suture-probe and silk thread traction technique has been developed. This approach is both secure and effective, as well as being cost-effective.

Background: Patients with dacryocystitis should be treated for their infection by endoscopic dacryocystorhinostomy (EN-DCR) before any intraocular surgery. However, there is no unified standard for the specific time interval between the two surgeries. This study aimed to determine the appropriate interval for intraocular surgery in patients with previous EN-DCR for chronic dacryocystitis.

Methods: The medical files of all patients who underwent intraocular surgery after EN-DCR surgery in our hospital from 2016 to 2019 were reviewed. The EN-DCR data of patients undergoing intraocular surgery at different time intervals and the incidence of endophthalmitis after intraocular surgery were compared.

Results: A total of 116 patients (92 females and 24 males, mean age 64.06±7.78 years) underwent EN-DCR and intraocular surgery met the inclusion criteria. The interval between EN-DCR and intraocular surgery varied from 5–475 days. The number of patients undergoing cataract surgery after EN-DCR is the largest (75, 64.7%). All patients (100%) who had previously undergone EN-DCR did not develop endophthalmitis infection after intraocular surgery at a follow-up of 12 months.

Conclusions: For patients with dacryocystitis who have undergone EN-DCR surgery, there is no time limit when choosing the timing of intraocular surgery. For patients requiring intraocular surgery, operation can be arranged as soon as possible to solve their problems as long as the patients had patency on lacrimal passage irrigation and no secretions.

Background: Using a randomized controlled trial (RCT), to assess the efficacy of the folded technique of self-adherent wrap to eyes after orbital tumour extirpation and compare it with the classic technique.

Methods: A single-centre, prospective, randomized, controlled study was conducted among 128 patients who underwent orbital tumour extirpation in this study. The folded and classic techniques of applying self-adherent wraps were randomly allocated to patients (1:1). The primary endpoint was the interface pressure on the affected eye. Secondary efficacy endpoints were the interface pressure above and below the ear of the affected side, above the ear of the non-affected side, and discomfort scores. Postoperative complications were observed for 24 hours.

Results: The interface pressure with the folded technique on the affected eye was neither inferior nor superior to the classic technique (1.33±0.07 vs. 1.41±0.09 mmHg, P=0.480). Most importantly, the pressure at three other points outside of the affected eye, including above and below the ear of the affected side, and above the ear of the non-affected side, were significantly higher when using the classic technique than when using the folded technique (P=0.041, 0.019, and 0.047, respectively). Discomfort scores were higher in the classic technique group than in the folded technique group (2.93±0.30 vs.1.52±0.19, P≤0.001).

Conclusions: Findings demonstrated the advantages of using folded technique to apply self-adherent wrap for wounds after orbital tumour extirpation with lower interface pressure outside of the affected eye and patient discomfort scores, without influencing pressure on the affected eye comparing with the classic technique.
