Intraocular tuberculosis remains a diagnostic and management conundrum for both ophthalmologists and pulmonologists. We analyze the efficacy and safety of anti-tubercular therapy (ATT) in patients with intraocular tuberculosis and factors associated with favorable outcome. Twenty-eight studies are included in this review, with a total of 1,917 patients. Nonrecurrence of inflammation was observed in pooled estimate of 84% of ATT-treated patients (95% CI 79–89). There was minimal difference in the outcome between patients treated with ATT alone (85% successful outcome; 95% CI 25–100) and those with concomitant systemic corticosteroid (82%; 95% CI 73–90). The use of ATT may be of benefit to patients with suspected intraocular tuberculosis; however, this conclusion is limited by the lack of control group analysis and standardized recruitment and treatment protocols.

Combined phacoemulsification and trabeculectomy is able to achieve greater reduction in intraocular pressure (IOP), higher rates of complete surgical success and fewer postoperative manipulations and visits compared with combined phacoemulsification and Xen implantation in glaucomatous eyes.Purpose: Our study aims to compare and understand the differences between the efficacy and safety of XEN45 implantation and trabeculectomy in Asian eyes with glaucoma. Materials and Methods: This was a retrospective, single-center, comparative study of consecutive patients who underwent combined phacoemulsification and trabeculectomy (Phaco-Trab) from January 2013 to June 2014 and combined phacoemulsification and XEN45 implantation (Phaco-Xen) from May 2017 to September 2018 in a tertiary Ophthalmology center in Singapore. Outcome measures included IOP, number of anti-glaucoma eyedrops, success rate, factors leading to success/failure, number of postoperative interventions and visits required, and surgical complications.Results: A total of 137 eyes (91 Phaco-Trab, 46 Phaco-Xen) were included. Phaco-Trab group had greater mean IOP reduction at all time points beyond postoperative month (POM) 1 (mean difference 2.9 to 3.8 mm Hg; P < 0.05), and greater reduction in mean number of antiglaucoma eyedrops beyond POM3, thought this was not statistically significant. At POM12, complete success was achieved in 83.5% in Phaco-Trab and 52.2% of Phaco-Xen group, respectively (P < 0.001). There was no significant factor associated with surgical failure, other than the difference in surgical procedure. Phaco-Trab group required fewer number of postoperative interventions (P = 0.009), with only a mean of 0.1 bleb interventions required per patient, versus 1.5 in Phaco-Xen group (P < 0.001). Safety profiles in both groups were comparable, with no statistically significant difference in intraoperative/postoperative complications. Conclusion:Phaco-Trab has significantly higher reduction in both IOP and number of antiglaucoma medications compared with Phaco-Xen group, with greater surgical success and fewer postoperative manipulations and visits. Safety profiles were comparable.

Our findings suggest that retinal microvasculature is associated with both disease severity and complications in young patients with T1DM.

Background To understand the differences between two different optical coherence tomography angiography (OCTA) devices in detecting glaucomatous from healthy eyes by comparing their vascular parameters, diagnostic accuracy and test-retest reliability. Methods A cross-sectional observational study was performed on healthy and glaucoma subjects, on whom two sets of OCTA images of optic disc and macula were acquired using both AngioVue (Optovue, USA) and Swept Source (Topcon, Japan) OCTA devices during one visit. A novel in-house software was used to calculate the vessel densities. Diagnostic accuracy of the machines in differentiating healthy versus glaucomatous eyes was determined using area under the receiver operating characteristic curve (AUROC) and test-retest repeatability of the machines was also evaluated. Results A total of 80 healthy and 38 glaucomatous eyes were evaluated. Glaucomatous eyes had reduced mean vessel density compared to healthy controls in all segmented layers of the optic disc and macula using AngioVue (p ≤ 0.001). However, glaucomatous eyes had higher mean vessel density on optic disc scans using Swept Source, with lack of statistically significant difference between healthy and glaucomatous eyes. The AUROC showed better diagnostic accuracy of AngioVue (0.761–1.000) compared to Swept Source (0.113–0.644). The test-retest reliability indices were generally better using AngioVue than Swept Source. Conclusions AngioVue showed better diagnostic capability and test-retest reliability compared to Swept Source. Further studies need to be undertaken to evaluate if there is any significant difference between the various machines in diagnosing and monitoring glaucoma.
