Unilateral optic disc pit and orbital cyst in an eye with normal axial length.

Orbital cyst and optic disc pits are both congenital embryological anomalies. Orbital cysts occurring in association with optic disc colobomata and microphthalmic eyes have been widely reported in literature. The authors describe the case of a 69-year-old man with an asymptomatic orbital mass, who was investigated and found to have a coexistent optic disc pit and orbital cyst. The axial length was normal. Visual acuity was reduced due to epiretinal membrane at the macula as a consequence of serous maculopathy secondary to the optic disc pit. No active intervention was offered due to poor visual potential, and no changes in the cyst occurred over time. This is an unusual case of coexistent orbital cyst and optic disc pit in an eye with normal axial length, although the dual pathology has previously been described in a microphthalmic eye.

Persistent fetal vasculature and spontaneous hyphema in a patient with Klippel-Trénaunay-Weber syndrome.

Klippel-Trénaunay-Weber syndrome is characterized by the triad of capillary malformations (usually port-wine stains), varicose veins or venous malformations of unusual distribution, and soft-tissue or bony hypertrophy of an extremity. The syndrome can be diagnosed on the basis of 2 of these 3 features. In the atypical form of the syndrome, capillary malformations may be absent. Recognition is possible during infancy or early childhood, and evaluation and treatment is important to minimize morbidity. We describe the case of an 11-year-old girl who presented with hyphema after a Valsalva maneuver and was found to have persistent fetal vasculature in the affected eye. She had systemic features of Klippel-Trénaunay-Weber syndrome. Magnetic resonance imaging, magnetic resonance angiography, and magnetic resonance venography scans of the brain and orbits were normal. Magnetic resonance imaging scan of the left hypertrophied lower limb revealed venous malformations leading to soft-tissue hypertrophy. To our knowledge, this is the first case of persistent fetal vasculature and hyphema in a patient with Klippel-Trénaunay-Weber syndrome.

Cutaneous larva migrans with optic disc edema: a case report.

INTRODUCTION: A rare case of optic disc edema associated with cutaneous larva migrans is presented. To the best of our knowledge, this has not been previously reported in literature. Joint management by ophthalmology and tropical medicine teams proved most beneficial for our patient, facilitating correct diagnosis, appropriate investigations and instigation of suitable treatment. CASE PRESENTATION: A 45-year-old Caucasian man, a naturalist, from the UK developed cutaneous larva migrans while in Kenya and presented to us with visual disturbance secondary to unilateral optic disc edema. This resolved after receiving a single dose of ivermectin and visual acuity reverted to normal. CONCLUSION: To the best of our knowledge, optic disc edema associated with cutaneous larva migrans has not been previously reported. This case highlights the importance of taking relevant history of recent travel to endemic areas affected by the nematodes in patients presenting with optic disc edema, and pertinent questioning regarding non-ocular symptoms, including skin lesions. In this case, a history of recent foreign travel and treatment for skin lesions was crucial.
