Purpose: To present a treatment regimen for Brucellosis endophthalmitis that resulted in a good visual outcome. Additionally, we conducted a literature review on the treatment and visual prognosis of related cases.

Case presentation: A 49-year-old woman with the chief complaint of decreased vision and redness in the right eye was initially diagnosed with noninfectious uveitis and prescribed high-dose steroids which led to transient improvement followed by a decline in vision. An infectious cause was suspected. Metagenomic next-generation sequencing of vitreous fluid and serological testing confirmed Brucella melitensis infection. The patient underwent vitrectomy combined with six intravitreal injections of ceftazidime in the right eye in addition to systemic antibiotic treatment. The intraocular inflammation was completely resolved, and the visual acuity recovered to 20/25, which is the best-documented recovery in Brucella endophthalmitis cases, as revealed by the literature review.

Conclusion: Vitrectomy combined with repeated intravitreal injections of ceftazidime can enhance the treatment for brucellosis endophthalmitis and achieve a better visual prognosis.

Purpose: To quantify the risk of posterior capsule rupture (PCR) in fellow-eye phacoemulsification surgery and to determine risk factors.

Methods: We pooled data from 8 United Kingdom sites for patients undergoing bilateral non-simultaneous phacoemulsification. Main outcome measures were the incidence and risk factors of the development of PCR during the fellow-eye phacoemulsification.

Results: We included 66,288 patients with a mean age of 75.3 ± 10.2 years. PCR during phacoemulsification occurred in the first eye in 932 patients (1.4%) and the fellow eye in 1039 patients (1.5%). The risk of fellow eye developing PCR in patients with PCR in the first eye was significantly higher than in patients without first eye PCR: 30 patients (3.2%) vs. 1009 (1.5%), respectively (odds ratio (OR) = 1.7, 95% confidence interval (CI) = 1.1-2.7). Other risk factors for fellow-eye PCR included zonular dialysis (OR = 5.4, CI = 3.3-7.8) and advanced cataract (OR = 2.8, CI = 2.1-3.7).

Conclusions: History of PCR in the first-operated eye is an independent risk factor for PCR in the fellow eye.

Purpose: Understanding the current role and efficacy of endocyclophotocoagulation (ECP) compared to ab-interno canaloplasty with or without trabeculotomy (OMNI), combined with cataract extraction and lens implantation (CEIOL), for the management of uveitic glaucoma (UG) is limited.

Methods: All UG patients ≥18 years old with ≥6 months of follow-up data (15.2 ± 5.9 months) after CEIOL combined with either ECP or OMNI from August 2019 to May 2022 at a single academic center were retrospectively reviewed [22 eyes of 15 patients (8 ECP, 14 OMNI)]. Surgical success was considered intraocular pressure (IOP) ≤21 mmHg and a reduction of baseline by ≥20% for two consecutive final visits without hypotony, additional surgery, or loss of light perception. Uveitic control was considered a <2-step increase in anterior chamber (AC) cell grade, <3+ AC cell grade, and no increase in steroid drop use at 3 months postoperatively. Secondary outcome measurements included postoperative change in IOP, glaucoma medications, best corrected visual acuity (VA), AC cell grade, and steroid drop frequency.

Results: Baseline ocular and preoperative characteristics of eyes (age, sex, laterality, uveitic location, systemic immunomodulating therapy, visual acuity, IOP, number of glaucoma medications, AC cell grade, and steroid drop frequency) did not significantly differ except for greater racial diversity in the ECP group. 62.5% eyes were surgically successful in the ECP group and 85.71% in the OMNI. Between-group analysis showed greater IOP reduction in the OMNI group (p < .05), but no difference in reduction of glaucoma medications (p = .33). No eyes displayed a two-step increase in or >3+ AC cell grade, however, 50% and 64.29%, respectively, increased steroid drop use. Between groups, no difference in the change of AC cell grade (p = .98) or steroid drop use (p = .84) was seen.

Conclusions: Both interventions improved visual acuity, IOP, and glaucoma medication use, however, OMNI was more successful at reducing IOP long term. An increase in steroid drop frequency may be the cost of a prolonged post-surgical inflammatory course related to underlying uveitis regardless of surgical approach.

Purpose: To compare the long-term outcomes of mucosal-sparing mechanical endoscopic dacryocystorhinostomy (MMED) for primary acquired nasolacrimal duct obstruction (PANDO) with or without silicone intubation.

Methods: An 11-year follow-up study of the Silicone intubation in Endoscopic Dacryocystorhinostomy (SEND) randomized controlled trial (RCT) was conducted at a university-affiliated dacryology clinic from December 2019 to March 2023. Questionnaires on symptoms, anterior segment examination, endoscopic examination with functional endoscopic dye test (FEDT) and FICI grading, and ostial size measurements using Image J software were performed by a masked ophthalmologist. The primary outcome was surgical success, defined by Munk's score ≤1 and a positive fluorescein endoscopic dye test. Secondary outcomes included risk factors for failure and outcomes of revision surgeries.

Results: Fifty-three of the original 118 patients were evaluated at 155 ± 21 (136-218) months postoperatively. Seventy-seven percent (46/60) ostia remained successful, including 70% (19/27) of unstented and 82% (27/33) of stented ostia (p = .3). Stented ostia had larger size (p = .003), but this did not confer higher success (p = .14). Successful ostia had higher FICI scores and better ostial dynamicity (p < .05). Ostium movement was the only parameter associated with surgical success on multivariate analysis (OR 13.1, p = .01). Four (1 stented) underwent revision MMED, intraoperative mitomycin-C, and 12-week intubation. All revision ostia were functional after 141 ± 43 months.

Conclusions: Surgical success of MMED after 11-years was 77%, a notable reduction compared to 96% success at 1-year. Statistical advantage of silicone intubation for primary MMED was not demonstrated, though clinically, stented ostia had a higher success (82% vs 70%). The presence of a dynamic internal common opening was highly associated with long-term surgical success.
