Investigation and Analysis of the Causes of Disabling Blindness

Various conditions causing blindness ranges from congenital or acquired. Congenital causes are developmental abnormalities like coloboma, nanophthalmos, congenital glaucoma, congenital cataract. Acquired causes like macular degeneration, phthisis bulbi, corneal opacity, retinitis pigmentosa, optic atrophy etc. affecting one or both eyes making the patient mild to severely handicapped.With this study, we can identify various causes affecting the vision of the patient. By knowing extent of the disability either we can counsel the patient those who having sufficient vision to deliver the work or we can recommend the patients those who are really blind for the pension scheme. In turn we can reduce their financial burden to the family and society.
