Sunrise in the eye: Bilateral superonasal lens subluxation in Marfan syndrome.

To describe the case of a patient with Marfan syndrome who had bilateral superonasal lens subluxation. The case of a male patient, aged 18, who complained of having impaired vision in both eyes (BE) since he was a toddler, was presented. On examination of the patient, features suggestive of Marfan syndrome were revealed, as well as bilateral intraocular lens subluxation. The patient was refracted and glasses were recommended, which improved his vision. The patient was referred to the cardiology, orthopedic, and dental departments for a multidisciplinary approach to prevent complications and further management. Lens subluxation is frequently presented as a primary clinical manifestation of Marfan syndrome. It can vary from asymptomatic, which is seen only after pupillary dilation, to significant subluxation, in which the equator of the lens in the pupillary axis causes diplopia or decreased vision. This case underscored the importance of considering the rare feature of Marfan syndrome.
