Trauma (21.4%), complicated cataract surgery (15.7%), and silicon oil tamponade (14.3%) were common causes of secondary glaucoma. There was significant delay in diagnosis in primary compared to secondary glaucoma (57.57% vs 32.85%) and non-compliance was significantly higher in primary glaucoma (34.3% vs 17.1%, p\u2009=\u20090.01). In univariate analysis, literacy, income status, locality, and delayed or missed diagnosis were found to be significant (p\u2009&lt;\u20090.05) according to visual acuity criteria. Out of the 33 patients who had undergone glaucoma filtration surgery, 18 (54.5%) were in the end-stage group. While 105 (77.2%) of 136 patients who were not subjected to any glaucoma filtration surgery reached end-stage glaucoma as per visual fields criteria (p\u2009=\u20090.011).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Lack of awareness, delayed diagnosis, low literacy, and income were associated with poor visual outcome.
