RESUMO
A rare case of fibrous histiocytoma in an infant is described. The tumour appeared to arise in the medial orbit, invading the ethmoid and maxillary sinuses. Surgical and medical management, and the subsequent clinical course in a 11 year follow-up period are described. Histogenesis of this primary mesenchymal tumour is discussed.

A case of oculocutaneous albinism is described in which bilateral Axenfeld's anomaly co-exists. Progressive elevation of intraocular pressure required treatment and this complication has not been reported. Different hypotheses regarding the co-existence of these conditions are reviewed.

A procedure for dealing with Tenon's capsule in squint surgery on the horizontal muscles, which preserves intact the relations of the various expansions of Tenon's capsule, distorts and damages them as little as possible and replaces Tenon's capsule as an intact layer over the muscle at the end of surgery is outlined. It depends on adequate fixation and the avoidance of damage to and distortion of Tenon's capsule by the use of muscle hooks to 'fish' for the muscle. It is claimed that this method produces less fibrosis around the muscle post-operatively and allows a better final result.

During the past 2 years, 44 patients (71 eyes) had pan-retinal photocoagulation by argon gas laser for proliferative diabetic retinopathy. All except 9 eyes benefitted from the treatment, peripheral and disc vessels showing regression. Many of the patients needed, or will need, further laser treatment. The main complications of treatment were slight or moderate constriction of the visual field, poor night vision and macular oedema.

A terylene implant, to which the tissues can be sutured directly, has been used after enucleation and evisceration since 1958. An advantage is that it can be implanted in the orbit as a secondary procedure some time after enucleation. It is easy to insert, gives fair motility and is well tolerated. It is a satisfactory implant for routine use.
