Aim: To analyse the demography, clinical features and outcome of patients presented with acute binocular diplopia at a tertiary eye care centre of Kerala. Materials and Methods: A retrospective review of medical records of patients presented with acute ( Results: 161 eyes of 88 (54.65%) males and 73 (43.34%) females with a mean age of 55.71 years (range 6 to 93 years) were included. Isolated cranial nerve palsies were the most common cause for acute diplopia (n=142, 88.2%) and included pupil sparing 3 nerve palsy (n=38), pupil involving 3rd nerve palsy (n=8), 4 nerve palsy (n=17) and 6th nerve palsy (n=79). Microvascular ischemia (n=119), traumatic (n=10), combined cranial nerve palsy (n=6), Idiopathic (n=13), Ocular myasthenia (n=5), Inter nuclear ophthalmoplegia (INO) (n=3), Parkinsonism (n= 1), Progressive Supra Nuclear Palsy (n=1) and decompensated comitant strabismus (n=3) were the other causes. Diabetes mellitus (n=102, 63.3%) was the most common vasculopathic factor followed by hypertension. Most patients (n=144, 89.4%) were relieved of their symptoms within six months. Conclusion: Acute binocular diplopia, though an alarming and distressing condition, had very good prognosis in our patients. Meticulous clinical examination and investigations can establish the diagnosis in most of the cases. Keywords: Diplopia, Nerve palsy.
