Microphthalmia involves eyes with total axial length of at least 2 standarddeviations below age-similar controls. This case report presents an unusual formof microphthalmia, the posterior microphthalmia which has never been reportedin Pakistan before. It also emphasises on the importance of use of Opticalcoherence tomography (OCT) for the diagnosis of posterior micropohthalmia. A7 year old boy presented to us with bilaterally decreased vision and was found tohave bilateral high hypermetropia. His fundal examination showed blurred opticdisc margins and dolphin - shaped elevated pappillomacular fold extending fromthe fovea to the optic disc in both the eyes. OCT showed elevated neurosensoryretina with normally attached retinal pigment epithelium. This confirmed thediagnosis of posterior Microphthalmia. The use of OCT thus aids in not justestablishing the diagnosis of posterior microphthalmia but also prevents us fromdeveloping the wrong diagnosis of papilledema and carrying out anyunnecessary investigations.Key words: Posterior microphthalmia, High hypermetropia, Optical coherencetomography, Pseudopapilledema.
