Abstract
Morning glory disc anomaly is a rare malformation characterized by an ectasia of the posterior pole of the fundus involving the optic disc. Embryologically, there are some theories for its pathogenesis, including primary mesenchymal abnormality, defective closure of the embryonic fissure, and basic defect of mesoderm combined with dynamic disturbance between the relative growth of mesoderm and ectoderm. However, the exact mechanism is still unknown. It is usually unilateral and occurs more frequently in women. Visual acuity is 20/200 or worse in 90 % of cases, but it can be as good as 20/20 [1]. Retinal detachment occurs in 30 % of cases, and many are non-rhegmatogenous with subretinal fluid accumulating around the optic disc [2]. It is usually non-contractile, but in extremely rare cases, it can exhibit contractile movements [3–5]. Here we present a contractile morning glory disc anomaly case with a video recording of the contractions.
