Spontaneous hematic cysts of the orbit presenting with acute proptosis. A report of three cases.

Three cases of spontaneous hematic cyst of the orbit are described. All cases presented with acute onset of proptosis, conjunctival chemosis, choroidal folds, restricted ocular movement, and optic nerve compression syndrome with very poor vision. A computed tomography scan demonstrated a cystic lesion situated in the upper part of the orbit. Exploration revealed a cyst containing chocolate-colored fluid. Visual recovery was complete in two of three cases. There was no definite history of trauma in all three cases. Chronic hematic cysts have been described recently, but cases with acute onset such as ours have not to our knowledge been described clearly.

Corneal blindness in Singapore and its prevention.

The pattern of corneal disorders in Singapore is different from that seen in the western countries, and in the developing countries. Dendritic corneal ulceration, keratoconus and corneal dystrophy are relatively uncommon. Bullous Keratopathy, however, is on the increase, due mainly to the increasing number of cataract operations done and to the use of intraocular implants. Other major corneal disorders in Singapore are Exposure Keratitis and Neurotrophic Keratitis. The management of the various corneal disorders are discussed. Prevention is possible especially in those disorders due to iatrogenic factors. Constant vigilance and care are called for to prevent unnecessary surgical trauma and corneal blindness.
