Abstract
In the present study, total of 110 patients were enrolled; maximum patients 60 (54.5%) were reported in the age group of 51 to 60 years, male patients were 63 (57.3%) and female patients were 47 (42.7%). ● Total 15 (13.6%) patients were observed with a family history of glaucoma. ● 14 (12.8%) patients observed with myopia. ● 40 (36.3%) patients observed with increased IOP. ● 43 (39.1%) patients observed with increased CD ratio. ● 43 (39.1%) patients had DM co-morbidity. ● 44 (40%) patients had SHTN co-morbidity. ● No female was reported with abnormal visual field in V3, whereas 2 (3.2%) males were observed with abnormal visual fields in V3. ● The patients with abnormal visual field with 1 (3.4%) and 1 (4.8%), respectively were found in the age group of less than 50 years and more than 60 years. ● The abnormal visual field was observed in both groups with or without a family history. of glaucoma with 1 (7.7%) and 1 (1%) patients. ● 2 (2.1%) patients were observed with abnormal visual field in V3 in the non-myopia group, whereas no patients were found with the abnormal visual field in myopia group patients. ● Patients with DM are observed with significantly higher in static visual field in V 3, 16 (37.2%) ,whereas patients in without DM group showed only 4 (6%) patients in static visual field category. ● Most of the patients in both groups were observed in normal visual field in V3 with 29 (65.9%) and 59 (89.4%) patients in SHTN and non SHTN group groups, respectively. ● In the present study, it was found that in patients with 22 abnormal visual field in V1, 2 (9.1%) patients had abnormal visual field in V3 and 20 (90.9%) patients with static visual field V3. Whereas patients with normal visual field V1, observed with no abnormal and static visual field in V3.And the patients with normal visual field in V2, 88 (100%) observed with normal visual field in V3. CONCLUSION: The prevalence of POAG in Glaucoma suspect with or without risk factor was found to be 1.8%. ● The risk factors like family history, advancing age, increased IOP and systemic risk factors like diabetes mellitus and hypertension are found to have notifiable relationship with the development of POAG but statistically not significant in this study. ● The risk factors like increased CD ratio and high myopia showed no significant relationship with the development of POAG in this study. ● So the present study highlights the importance of people with family history of glaucoma, systemic hypertension, diabetes mellitus and those with static visual field must be highly vigilant and any subtle signs of visual disturbance they must periodically undergo ocular examination and visual field evaluation to detect early field changes, which aids in early treatment and monitoring the progression of disease. ● This study also emphasizes the need for further extensive studies to evaluate the correlation of risk factors and progression of the glaucomatous damage over time. ● To overcome the limitations in usage of visual field analysis, OCT imaging of ONH and RNFL analysis can be utilized. All these investigations when combined can play a role in effective spacing the screening of visual field and diagnosing the early stages of glaucoma. ● This will pave the way to efficient and successful management of glaucoma cases.
