Abstract

Slit lamp biomicroscopy provides invaluable diagnostic information as to the nature of ocular abnormalities and disease processes. As such, the emphasis to be presented in this discourse is biomicroscopic interpretation, as opposed to simple observation, with each major ocular structure discussed in turn.

The newer generation intraocular lens power calculation formulae in anterior chamber implants.

One hundred and fifty-one eyes with anterior chamber implants and a best corrected visual acuity of at least 6/12 were studied to compare the predictive accuracies of the newer generation intraocular lens power calculation formulae. There was no statistically significant difference between the predictive accuracies of the SRK (Sanders-Retzlaff-Kraff), SRK II, SRK/Theoretical (SRK/T) and Holladay formulae. All these four formulae were more accurate than the Binkhorst II formula.

A gel of glycosaminoglycans lining the anterior and posterior chambers in man: histochemical evidence at light and electron microscopy levels.

A thin mucous layer covers the ciliary body and iris epithelium and becomes thicker in the anterior chamber where it covers the anterior surface of the iris, the chamber angle and corneal endothelial surface. It is especially thick at the chamber angle, where it adopts a meniscus shape with the concavity towards the anterior chamber. Cetylpiridinium chloride along with glutaraldehyde was used to precipitate this layer of mucous substance lining the anterior and posterior chambers of the human eye. The staining of the precipitate by cationic dyes suggests that glycosaminoglycans are main components. The specific characterisation with anti-hyaluronic acid monoclonal antibody labelled with colloidal gold reveals the presence of hyaluronic acid in the precipitate. Long unbranched hyaluronic acid molecules may form the skeleton of a gel able to trap and hold virtually any other macromolecule suspended in the aqueous humour. A possible role of such a gel in the regulation of aqueous humour outflow is discussed.

Complications and management of the filtration bleb.

Filtration surgery is the commonest operation performed for closed angle or open angle glaucoma when medical treatment or laser trabeculoplasty has failed to control the intraocular pressure. It is characterized by the formation of an artificial drainage fistula between the anterior chamber and subconjunctival space. The successful operation is evidenced by the appearance of a subconjunctival filtration bleb which in turn depends on the patency of this pathway. Despite numerous modification, the procedure trabeculectomy first described by Sugar in 1961 and later on popularized by Watson and Cairns in 1968 is the most popular filtration surgery performed nowadays. It is a safe, relatively easy operation which carries a success rate of around 76% to 84% with a small complication rate. Repeat filtration surgery, however, is often less successful, making a successful initial surgery critically important. A successful outcome of filtration surgery can be enhanced by preoperative preparation, meticulous technique with modification for individual case, and early identification and prompt treatment of the complications arisen.
