Abstract Background: The present study aimed to compare visual field progression in new-diagnosed exfoliation versus open-angle glaucoma patients. Methods: Retrospective study. The study included patients with new-diagnosed primary open-angle and exfoliation glaucoma. All patients were followed for three years with reliable visual fields. At least five reliable fields were needed for inclusion. Exfoliation and open-angle glaucoma were defined based on the European Glaucoma Society guidelines. Visual field evaluation was performed using the software threshold 24-2 of the Humphrey Field Analysis. Outcomes: Visual field progression. For visual field progression, three different strategies were used: mean deviation (MD), visual field index (VFI), and the guided progression analysis (GPA). Results: The study included 128 subjects, of the 54 in the open-angle and 74 in the exfoliation glaucoma group. The MD difference values were higher in the exfoliation (-3.17 dB) than in the primary open-angle (-1.25 dB) glaucoma group in the three-year follow-up period. The difference between groups was significant (t-test, p=<0.001). The difference in VFI was calculated for the three years follow-up period. The difference was higher in the exfoliation (-7.65%) than in the primary open (-1.90%) glaucoma group (t-test, p=<0.001). The GPA showed progression in 58% of cases in exfoliation, and 13% in primary open glaucoma group (Chi-square, p=<0.001). Conclusion: The present study found a more frequent and faster visual field progression in exfoliation than in primary open-angle glaucoma patients. New-diagnosed exfoliation glaucoma patients must be controlled and treated more strictly than primary open-angle glaucoma patients to avoid visual field deterioration.

Background: The most common treatment for primary open-angle glaucoma (POAG) is the daily use of eye drops. Sustained-release drug delivery systems have been developed to improve patient adherence by achieving prolonged therapeutic drug concentrations in ocular target tissues while limiting systemic exposure. The purpose of this study is to compare the efficacy and safety of bimatoprost inserts with bimatoprost eye drops in patients with POAG and ocular hypertension (OH). Methods: We include OH and POAG patients aged between 40 and 75 years-old. Both OH and POAG patients had intraocular pressure (IOP) greater than 21 and ≤30 mmHg at 9:00 am without glaucoma medication and normal biomicroscopy. Five normal patients with IOP≤14 mmHg constitute the control group. A chitosan-based insert of bimatoprost was placed at the upper conjunctival fornix of the right eye. In the left eye, patients used one drop of LumiganTM daily at 10:00 pm. For statistical analysis, we used a two-way analysis of variance (ANOVA), Student t-test, and paired t-test. Results: Sixteen POAG and 13 OH patients with a mean age of 61 years were assessed. In both eyes, IOP reduction was similar during three weeks of follow-up (19.5±2.2 mmHg and 16.9±3.1 mmHg), insert, and eye drop, respectively; P=0.165). The percentage of IOP reduction in the third week was 30% for insert and 35% for eye drops (P=0.165). No intolerance or discomfort with the insert was reported. Among the research participants, 58% preferred the use of the insert while 25% preferred eye drops, and 17% reported no preference. Conclusions: Bimatoprost-loaded inserts showed similar efficacy to daily bimatoprost eye drops during three weeks of follow up, without major side effects. This might suggest a possible change in the daily therapeutic regimen for the treatment of POAG and OH.

Introduction: Glaucoma is one of the major causes of irreversible blindness. In Nepal, the most common type of Glaucoma seen is Primary Open Angle Glaucoma. There are many risk factors associated with Primary Open Angle Glaucoma. The main objective of the study was to compare ocular biometric parameters in patients diagnosed with Primary Open Angle Glaucoma and age matched controls. Material and methods: This is a hospital based cross sectional study done at Mechi Eye Hospital. The study included 137 cases of Primary Open Angle Glaucoma and 75 normal individuals as control. Axial length (AL), anterior chamber depth (ACD), Keratometry ‘K’ value and Central Corneal Thickness (CCT) were measured. Mann – Whitney U test was used for statistical analysis. Results: Mean age in Primary Open Angle Glaucoma group was (55.25 ± 10.16 years) and in the control group was (60.96 ± 10.91 years). Axial length in the Primary Open Angle Glaucoma group (23.16 ±1.19 mm) was deeper as compared to the control group (22.69 ±0.89 mm), the difference was statistically significant (p<0.001). Anterior chamber depth (ACD) was statistically deeper in the Primary Open Angle Glaucoma group (3.05 ±0.51 mm) as compared to the control group (2.86 ±0.46 mm), (p<0.01). Central corneal thickness (CCT) was thinner in the Primary Open Angle Glaucoma group (519.5 ±36.25 um) as compared to the control group (525.40 ±37.77 um) but the difference was not found to be statistically significant (p<0.19). K value in Primary Open Angle Glaucoma (7.54 ±0.41mm) was higher than age-matched controls (7.58 ± 0.33mm) but the difference was not statistically significant (p<0.79). Conclusion: Patients with Primary Open Angle Glaucoma had longer Axial length (AL) and deeper Anterior chamber depth (ACD) as compared to normal individuals.

Purpose: The aim of this study is to compare the outcomes of micropulse transscleral cyclophotocoagulation between primary open-angle glaucoma, pseudoexfoliation glaucoma, and other types of secondary glaucoma. Methods: Outcomes of 96 consecutive patients with refractory, end-stage glaucoma treated with micropulse transscleral cyclophotocoagulation were retrospectively reviewed. Follow-up examinations were performed on a regular basis until 12 months postoperatively. Surgical successes were defined as maintaining intraocular pressure ⩽18 mmHg and ⩾20% reduction in intraocular pressure (criteria A), ⩽15 mmHg intraocular pressure and ⩾25% reduction in intraocular pressure (criteria B), and ⩽12 mmHg intraocular pressure and ⩾30% reduction in intraocular pressure from baseline (criteria C). Results: Ninety-six eyes of 96 patients (50 (52%) females, 46 (48%) males) were included. Among all eyes, 32 were primary open-angle glaucoma, 30 were pseudoexfoliation glaucoma, and 34 were other types of secondary glaucoma. The mean age was 59.37 ± 11.45 (range: 20–91) years. The mean follow-up period was 14.2 ± 3.9 (range: 12–16) months. At 12 months, the success rates of primary open-angle glaucoma, pseudoexfoliation glaucoma, and secondary glaucoma group were 68.75%, 66.6%, and 64.7% (p = 0.185) for criteria A; 56.25%, 53.3%, and 50% (p = 0.153) for criteria B; and 43.75%, 43.3%, and 38.2% (p = 0.146) for criteria C. Four patients (12.5%) in primary open-angle glaucoma group, 5 patients (16.6%) in pseudoexfoliation glaucoma group, and 14 (41.2%) patients in other secondary glaucoma group required reoperation during the follow-up (p < 0.05). Conclusion: Micropulse transscleral cyclophotocoagulation is an equally effective method of lowering intraocular pressure in patients with primary open-angle glaucoma, pseudoexfoliation glaucoma, and other types of secondary glaucoma. The rate of reoperation was higher in refractory secondary glaucoma patients.

Purpose. The Glaucoma Stereo Analysis Study, a cross-sectional multicenter collaborative study, used a stereo fundus camera (nonmyd WX) to assess various morphological parameters of the optic nerve head (ONH) in glaucoma patients. We compared the associations of each parameter between the visual field loss progression group and no-progression group. Methods. The study included 187 eyes of 187 patients with primary open-angle glaucoma or normal-tension glaucoma. We divided the mean deviation (MD) slope values of all patients into the progression group (<−0.3 dB/year) and no-progression group (≧−0.3 dB/year). ONH morphological parameters were calculated with prototype analysis software. The correlations between glaucomatous visual field progression and patient characteristics or each ONH parameter were analyzed with Spearman’s rank correlation coefficient. Results. The MD slope averages in the progression group and no-progression group were −0.58 ± 0.28 dB/year and 0.05 ± 0.26 dB/year, respectively. Among disc parameters, vertical disc width (diameter), disc area, cup area, and cup volume in the progression group were significantly less than those in the no-progression group. Logistic regression analysis revealed a significant association between the visual field progression and disc area (odds ratio 0.49/mm2 disc area). Conclusion. A smaller disc area may be associated with more rapid glaucomatous visual field progression.
