This study aims to examine the learning effects of Humphrey Field Analyser (HFA) in patients with glaucoma.Study design: Cross-sectional study.Methods: Twenty eyes of 12 patients (10 patients [83.4%] open-angle glaucoma, 1 patient [8.3%] angle-closure glaucoma, and 1 patient [8.3%] secondary glaucoma) were sent to HFA examination for three different sessions of examination. The inclusion criteria were patients with glaucoma who completed three HFA examinations.The results were analysed using ANOVA and Tukey’s post hoc test. The primary outcomes were reliability, global indices, and the threshold sensitivity between the three sessions.Results: Duration to complete the HFA test statistically decreased after the third session (first vs third session: 387 ± 96 vs 307 ± 93 sec; p = 0.017) as well as fixation loss (first vs third session: 0.25 ± 0.19 vs 0.05 ± 0.11: p = 0.001). False-negative results improved after the third session (first vs third session: 0.15 ± 0.15 vs 0.02 ± 0.03 p < 0.001). There was no statistically significant difference in false-positive, mean deviation, pattern standard deviation, and visual field index within the three sessions.Conclusions: There was shorter test duration, decreased fixation loss, and decreased false negatives in the third session of HFA, but there was no statistically significant change to the global indices. Experience has important effect on perimetry results. Thus, the learning effect should be taken into consideration for management ofpatients with glaucoma.","PeriodicalId":405983,"journal":{"name":"Malaysian Journal of Ophthalmology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130787729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Retropupillary iris-claw IOLs (RP-ICIOL) have gained popularity in recent years.Purpose: This study aimed to review the outcomes of RP-ICIOL implantation in two tertiary eye centres.Study design: Retrospective review.Methods: This is a retrospective study of 14 eyes of 14 patients who underwent Artisan RP-ICIOL implantation between November 2018 and December 2020 in two tertiary eye centres in Malaysia.Results: The mean age of patients was 51.5 ± 17.4 years with the range between 18 and 77 years old. There were ten (71.4%) males and four (28.6%) females. The IOL was implanted primarily in three eyes (21.43%) and as a secondary procedure in eleven eyes (78.6%).

Visual improvement of two or more lines in BCVA was observed in nine eyes (64.3%), no improvement in two eyes (14.3%), and worsening in three eyes (21.4%).

Study design: Prospective study analysing corneal parameters among patients with T2DM along with fluctuations in HbA1c.Methods: A prospective, single-centre, cohort study was carried out on T2DM patients with HbA1c > 6.5% from Kasturba Hospital, Manipal, India. The subjects underwent a comprehensive eye examination. One-hundred and twenty-two subjects who fulfilled the inclusion criteria were analysed using the Huvitz 9000A to measure anterior corneal curvature followed by ultrasound pachymetry to measure central corneal thickness (CCT) at baseline and after 3 months. A simple linear regression was used to compare the mean corneal parameters, CCT and anterior corneal curvature, for each group with the mean HbA1c. The mean difference was considered statistically significant only if the value was p < 0.05.Results: We observed a significant difference between baseline and follow-up levels of HbA1c (t = 2.487; df = 53; p < 0.05). Simple linear regression analysis showed a positive correlation and revealed a mean increase in CCT of 1.893 μm (p < 0.001) and a mean increase in anterior corneal curvature of 0.069 D (p < 0.005) for every unit increase in HbA1c.Conclusions: The present study showed that changes in CCT and anterior corneal curvature occur with respect to changes in HbA1c level. Thus, careful attention is required in considering HbA1c status when performing comprehensive eye examinations in diabetic patients.","PeriodicalId":405983,"journal":{"name":"Malaysian Journal of Ophthalmology","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131959848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Manual segmentation of the macular GCLIPL was performed using elliptical annuli with diameters of 4.5 mm. Subjects with VA < 6/9 were defined as having abnormal vision. Mann-Whitney U test was used to evaluate the relationship between vision and macular GCLIPL thickness. Data were analysed using SPSS version 22.0 software.Results: Forty study eyes (normal vision = 17 eyes; abnormal vision = 23 eyes) from 21 participants with spastic cerebral palsy were included. Most subjects were male (61.90%, n = 13) and the median age was 13 years (range from 7 to 29 years). The median visual acuity was 0.1 logMAR for subjects with normal vision and 0.3 logMAR for subjects with abnormal vision. Eyes with normal vision had higher average GCLIPL thickness (mean = 106.3 ± 27.85 μm) compared to eyes with abnormal vision (mean = 96.6 ± 36.47 μm). However, a significant association between GCLIPL thickness and visual impairment could not be established in this study.Conclusion: Our study demonstrated a reduction in macular GCLIPL thickness in cerebral palsy patients with visual impairment but did not fully support its use as surrogate marker of cerebral visual impairment due to study limitations.

Their relationship with perceived social support is also explored.Study design: Cross-sectional study involving 176 glaucoma patients.Methods: Patients with known psychiatric illness, physical limitations, and other visually debilitating ocular conditions were excluded. Measurement tools included the Hospital Anxiety and Depression Scale (HADS) and Multidimensional Scale of Perceived Social Support (MSPSS). Ocular examination parameters such as LogMAR visual acuity, mean deviation (MD) on standard automated perimetry, and intraocular pressure (IOP) were recorded along with sociodemographic and clinical history. Multivariate linear regression analysis was carried out to identify predictive factors for depression and anxiety.Results: The prevalence of depression and anxiety among glaucoma patients was 6.8% and 9.1% respectively. MSPSS scores were significantly lower in patients with depression (p = 0.019) and anxiety (p = 0.016). Patients with depression and anxiety had significantly worse visual acuity and MD values. After adjustment with multiple regression analysis, depression or anxiety were still significantly associated with MD values (depression b = -0.13, p < 0.001, whereas anxiety b = -0.10, p = 0.001) and MSPSS scores (b = -0.08, p < 0.001). IOP of the worse eye was associated with anxiety (b = 0.2, P = 0.002), whereas widowed status was associated with depression (p < 0.005).Conclusions: Analysed HADS scores in this study show depression and anxiety rates among glaucoma patients in this population are relatively low. Severe glaucoma and lack of perceived social support are significant predictive factors. The findings underline the importance of screening for depression and anxiety in glaucoma patients to provide psychosocial intervention where needed.","PeriodicalId":405983,"journal":{"name":"Malaysian Journal of Ophthalmology","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117191221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
