METHODS: We retrospectively evaluated the surgical outcome of the BGI with Supramid© 3/0 ripcord stent in patients with NVG. No tube ligation or venting slits were performed. Supramid was removed after 3mo if the target intraocular pressure (IOP) was not achieved. Surgical success was defined as IOP≤21 mm Hg with (qualified success) or without IOP-lowering medications (complete success).

RESULTS: Twenty-six eyes from 24 patients were included in the study. The median duration of follow-up was 4 [interquartile range (IQR)=1-5]y, ranging from 0.5 to 5y. IOP decreased by a mean of 24.2 mm Hg (59.7%); from a mean of 40.5±12.6 mm Hg at baseline to 16.3±11.9 mm Hg, P≤0.001. The number of glaucoma medications reduced from a median of 5 (IQR=5-6) to 1 (IQR=0-2, P≤0.001) at the final follow-up. Overall success rates were 88.0% at 1y, 34.8% at 3y, 66.7% at 4y, and 50% at 5y. Hypertensive phase (HP) in the first 3mo occurred in 15/26 eyes (57.7%) with a mean IOP of 31.1 mm Hg.

METHODOLOGY: A cross-sectional observational study was performed on patients diagnosed with MetS and compared to normal controls. All patients underwent ophthalmic and anthropometric examination, serological and biochemical blood investigations; and ocular imaging using spectral-domain optical coherence tomography. Patients with ocular pathology were excluded. Unpaired t-test was used to compare mean thickness between the two groups. One-way ANOVA with Bonferroni correction for multiple comparisons was used to compare mean thickness between different tertiles of MetS parameters, and a generalized estimating equation was used to correct for inter-eye correlation and to assess association between mean thickness and covariates.

RESULTS: Two hundred and forty-eight eyes from 124 participants (1:1 ratio of MetS patients to controls) were included. Age ranged between 30 to 50 years old, and mean age was 40 ± 6.6 years. RNFL thickness was lower globally (93.6 ± 9.9 μm vs 99.0 ± 9.3, p<0.001) and in the inferior (124.5 ± 17.5 μm vs 131.0 ± 16.4 μm, p = 0.002), superior (117.2 ± 16.0 μm vs 126.3 ± 14.4 μm, p<0.001) and temporal (65.5 ± 10.2 μm vs 69.5 ± 9.8, p = 0.002) sectors in MetS patients compared to controls. Only the central (237.0 ± 14.0 μm vs 243.6 ± 18.0 μm, p = 0.002) and inferior parafoveal (307.8 ± 20.9 vs 314.6 ± 14.6, p = 0.004) area of the macula was significantly thinner. The inferior RNFL sector had the most difference (mean difference = 9.1 μm). The Generalized Estimating Equation found that, after adjusting for age, diastolic blood pressure, BMI, HDL and obesity; the number of MetS components and elevated triglyceride levels were independent risk factors for reduced thickness in global RNFL (β = -4.4, 95% CI = -7.29 to -1.5, p = 0.003) and inferior parafovea (β = -6.85, 95% CI = -11.58 to -2.13, p = 0.004) thickness respectively.

METHODS: This retrospective study analysed data of 60 eyes from 30 patients with bilateral uveitic glaucoma who had undergone glaucoma surgery in both eyes on separate occasions. Humphrey VF progression was assessed using the Progressor software.

RESULTS: The pre-operative IOP between the FE (43.1 ± 7.7 mmHg) and SE (40 ± 8.7 mmHg) was not statistically significant (p = 0.15). IOP reduction was greater in the FE (64 %) than SE (59.7 %) post-operatively, but the mean IOP at the final visit in the FE (12.3 ± 3.9 mmHg) and SE (14.5 ± 7 mmHg) was not statistically different (p = 0.2). There was no significant change in mean logMAR readings pre and post-operatively (0.45 ± 0.6 vs 0.37 ± 0.6, p = 0.4) or between the FE and SE. The number of SE with CDR > 0.7 increased by 23 % compared to the FE. From 23 available VFs, five SE (21.7 %) progressed at a median of five locations (range 1-11 points) with a mean local slope reduction of 1.74 ± 0.45 dB/year (range -2.39 to -1.26), whereas only one FE progressed. However, there was no significant difference between mean global rate of progression between the FE (-0.9 ± 1.6 dB/year) and SE (-0.76 ± 2.1 dB/year, p = 0.17) in the Humphrey VF.

CASE PRESENTATION: A 22-year-old African gentleman presented with left nasal obstruction and epistaxis for 2 years and was diagnosed with nasopharyngeal carcinoma. He subsequently underwent embolization of the maxillary branch of the left ECA using Embozene® Microspheres - 250 μm in size before endoscopic tumour excision to reduce intra-operative bleeding. He complained of sudden painless profound visual loss in the left eye (LE) two hours after embolization. Visual acuity in LE was no light perception. Fundus examination showed pale retina with no cherry red spot. Arterial narrowing and segmentation were seen in all quadrants. A diagnosis of left ophthalmic artery occlusion was made. Despite immediate management including ocular massage and lowering of intraocular pressure, the visual loss remained. Retrospective review of digital subtraction angiogram showed an anastomosis between the left ophthalmic artery and anterior deep temporal artery as a potential route for microspheres migration.

METHODS: This cross-sectional observational study includes 127 eyes of 127 subjects. Patients were divided into PPG (51 eyes), PG (46 eyes), and normal controls (30 eyes) based on clinical optic disc assessment and Humphrey visual field changes. The Heidelberg Spectralis OCT machine using Glaucoma Module Premium Edition software was used to measure the retinal nerve fiber layer (RNFL) and Bruch's membrane opening-minimum rim width (BMO-MRW) to assess the optic nerve head and ganglion cell layer (GCL) thickness in the macula.

RESULTS: RNFL, MRW, and GCL thickness were all significantly thinner in PG compared to PPG and the normal group. The BMO-MRW parameters showed better specificity (>70%) at 90% specificity compared to both RNFL and GCL parameters to discriminate normal, PPG, and PG patients. All BMO-MRW parameters showed higher area under curves (AUC) compared to RNFL and GCL parameters with the highest AUC observed in the superotemporal sector of the BMO-MRW (AUC=0.819 and and 0.897 between normal and PPG and PG groups respectively).

METHODS: This is an open-labeled, randomized, prospective crossover study on fourty primary open angle glaucoma patients. Two weeks of washout period were followed by randomization to either once daily (OD, group A) or twice daily dosing (BD, group B) of LTFC for 4wk. After another 2-week washout period, the patients' treatment dose was crossed-over for another 4wk. IOP reduction alongside ocular and systemic side effects were evaluated.

RESULTS: Mean baseline IOP was 18.57±2.93 and 17.8±3.01 mm Hg before OD and BD dose respectively, (P=0.27). Mean IOP after BD dose was statistically lower (12.49±1.59 mm Hg) compared to OD (13.48±1.81 mm Hg, P=0.017). Although IOP reduction after BD dose was more (5.32±3.24 mm Hg, 29.89%) than after OD dosing (5.04 mm Hg, 27.14%), it did not reach statistical significance (P=0.68). Patients switched from OD to BD (group A) showed mean IOP reduction by 0.69 mm Hg [95% confidence interval (CI): -0.09 to 1.48 mm Hg, P=0.078]; but patients switched from BD to OD (group B) had significantly higher mean IOP by 1.25 mm Hg (95%CI: -2.04 to -0.46 mm Hg, P=0.006). BD dose had more ocular side effects albeit mild.

METHODS: A cross-sectional study was conducted from September 2020 to March 2021 in Ophthalmology Clinic Hospital Canselor Tuanku Muhriz Universiti Kebangsaan Malaysia (HCTM UKM). Subjects diagnosed with center-involved DME aged between 20 to 80 years who experienced delayed anti-VEGF injection were recruited. Level of depression, anxiety and stress were assessed using DASS-21 questionnaire. Statistical analysis using non-parametric tests were performed to determine the relationship between the DASS-21 score and duration of last injection, in those whose vision was affected by delayed injection and the relationship to the impact of COVID-19 pandemic. Statistical significance was denoted as p < 0.05.

RESULTS: A total of 86 respondents with median age of 69 years old participated in this study. Most respondents were Malays (n = 47,54.7%) males (n = 51, 59.3%), had education up to secondary level (n = 37, 43%), unemployed (n = 78, 90.7%), married (n = 72, 83.7%) and living with their family (n = 82, 95.3%). The number of intravitreal injections received was at least three times among the respondents (n = 81, 94.2%). More than half of the respondents (n = 46, 53.5%) had been postponed for more than 12 weeks and felt that their vision was affected after delayed intravitreal injection (n = 47, 54.7%). Most of the subjects did not experience depression, anxiety, or stress. However, there was a significant level of stress scores among those with delayed injection of 9 to 12 weeks (p = 0.004), and significant anxiety (p = 0.029) and stress (p = 0.014) scores found in subjects with vision affected due to delayed treatment.

METHODS: This is a retrospective observational study of OAG patients who underwent standalone or combined iStent procedures were reviewed. Inclusion criteria included age over 18 years and open angle on gonioscopy. Exclusion criteria were prior incisional glaucoma surgeries, missing data, or follow-up shorter than 6 months. The primary outcome was surgical success between the two groups after one year. Secondary outcomes included differences in IOP reduction and medication use.

METHODS: In this randomized, multi-arm parallel single-centre trial, 73 diabetics with dry eye disease (30 female and 43 male) aged 18 to 50 years were recruited. They were randomly assigned to four weeks of treatment of either TI 0.5 unit/drop, AT or NS four times per day. Tear sample analysis and clinical parameters of dry eye (Ocular Surface Disease Index (OSDI), tear break-up time (TBUT), corneal Oxford score and Schirmers test) were evaluated at baseline and four weeks later. Objective clinical parameters for corneal Oxford score and tear break-up time were assessed by two masked investigators.
