Acute idiopathic maculopathy is a relatively new clinical entity and on uncommon cause of sudden, severe, unilateral or bilateral, painless visual loss in young adults. The purpose of this article is to recognize the existence of this entity in South-East Asia and to highlight the condition which can be misdiagnosed because of relative non-familiarity of the general ophthalmologist with this condition. We report a case of acute idiopathic maculopathy presented to to the eye department, Baqai Medical University Hospital (Fatima Hospital) with sudden painless loss of vision in left eye of 50 years old house wife for the last 2days. Examination revealed vision reduced to finger counting one-foot in her left eye. Both eyes were otherwise unremarkable except a serous elevation of the retina at the posterior pole of the left eye. B-scan revealed no sub-retinal mass while FFA led to the final diagnosis. Patient was reassured of transient nature of visual loss. Vision started improving after 2-weeks from the onset and recovered to 6/9 by the end of six-weeks. Acute idiopathic maculopathy is also prevalent in our part of the world and it is prudent to include this condition in the differential diagnosis of all healthy, young adults presenting with sudden, painless visual loss and neural retinal detachment of the macula. Accurate diagnosis can be quite reassuring for the patient and save her from extensive work-up, unnecessary and sometimes harmful treatments.
