摘要:

An 87-year-old woman presented with a rapidly growing tumour at the nasal side of the upper eyelid. The clinical diagnosis was basal cell carcinoma. During surgery, the impression of malignancy was accentuated by the finding that even the conjunctiva had been invaded. Histological examination revealed an eccrine acrospiroma with, indeed, many mitoses but, on the other hand, a completely bening aspect. Besides, there was no recurrence after 1 year.

摘要:

28-year-old sportsman developed chest pain, dyspnoea, haemoptysis and swelling of the right leg. 8 weeks later he also complained of blurred vision. Ophthalmoscopy revealed subretinal infiltrates diagnosed as tumour metastases by fluorescein angiography. The patient died 10 weeks after the first symptoms. At autopsy large mediastinal embryonal carcinoma was diagnosed, and both eyes revealed choroidal metastases. This rare tumour usually involves young men and is invariably fatal within a few months. Exceptional bilateral choroidal metastases constituted the presenting sign.

摘要:

The authors present a case of exophthalmos caused by invasion from a hypo-physeal tumour, rare both for this type of metastasis and for the patient’s young age. Histological study of biopsy material enabled the tumour to be classified. Comparison of clinical and microscopic data helps towards a better understanding of the behavioui of invasive adenomas.

摘要:

The occurrence of congenital oculomotor apraxia in two children of the same family is described. The improvement of the ocular dysfunction in the older sister gave some hints to the benign nature of the condition and its tendency to recover with age. The possible pathophysiological mechanism underlying this anomaly is discussed.

摘要:

A simplified method for ptosis surgery has been used in 33 patients. The levator aponeurosis is exposed by the anterior approach. It is folded or excised and reattached to the anterior surface of the tarsus, matching the level and the contour of the two upper lids. The cosmetic appearance of the lid is improved by the skin closure technique. This method for ptosis surgery meets the anatomical and physiological needs best. It has given very satisfactory functional and cosmetic results.

摘要:

A variation to standard trabeculectomy is described, whereby the trabecular tissue flap is not completely excised, but dissected free, hinged at its nasal end and sutured diagonally across the scleral bed, to act as a wedge between the scleral flap and its bed, in an attempt to decrease the tendency of the sclera to scar into a watertight barrier. In addition, it is suggested that the trabecular flap acts as a wick that aids in the filtration of the aqueous humour. The technique has been used in 24 eyes with good to excellent, short-term, post-operative intraocular tension control in all but 2 patients. Mild complications like transient flat anterior chamber or blood cells in the aqueous occur at rates comparable to other filtering procedures.

摘要:

3 weeks after NaOH cauterization of rat corneas, the newly formed vessels were angiographically investigated by means of FITC dextran fractions. An angiographic picture similar to that of fluorescein Na was observed after intravenous administration of FD 3. A minimum diffusion of FD 40 could only be detected in the area of the distal terminal loops of the newly formed corneal vessels. FD 70 and FD 150 showed an angiographically similar behaviour with no diffusion in the whole area of neovascularization.

摘要:

In a series of 470 rhegmatogenous retinal detachments, the relation between the incidence of macular pucker and puncture of the subretinal fluid was studied. We found macular pucker in 7.1% of the cases where a drainage was performed and only in 3.2% of the cases where it was not. In 85% of these cases, the macular region was preoperatively detached.

摘要:

The effect of combined treatment with an oral β-blocking agent (propranolol tablets 40 mg twice a day) and a local α- and β-agonist (epinephrine eyedrops twice a day) was studied in 10 healthy volunteers. Propranolol was given in a double-blind randomized manner, while adrenalin was given unmasked. Propranolol and adrenalin proved to have an additive reducing effect on the intraocular pressure. The effect of propranolol alone was stronger than that of adrenalin.

摘要:

As part of the search for a bioengineering model of the eye, the interaction between instantaneous changes of pressure in the anterior and vitreous chambers are studied. A description of the experiments as well as data evaluation is given. The results indicate a linear relationship between the chambers and a diaphragm effect of the system lens-iris-zonula-ciliar body.
