Recent research during the last decade revealed evident pathogenic role of the vitreous in many diseases of the retina. Biomicroscopy is a modern tool to examine the vitreous that facilitates examination of the fundus. Biomicroscopic data may improve effectiveness of treatment.

Results of our clinical investigations can be summarised as follows:

We introduced clinical biomicroscopy in Hungary, and described basic features of the normal and pathologic vitreous. We demonstrated in vivo the entire course of the Cloquet's canal, saccular dilatations and obliteration in the anterior vitreous, and the radier structures of the surrounding vitreous. We added significant new data to the syndrome "Intrapapillary and perpapillary hemorrhage with incomplete posterior vitreous detachment". We reported a case of an otherwise healthy Caucasian patient, who suffered intrapapillary hemorrhage after complete vitreous detachment, demonstrating that this syndrome occurs not only in Asian myopic patients after partial posterior vitreous detachment.

Results of our examinations proved evidence, that biomicroscopy significantly enhances recognition of imminent retinal detachment, and improves effectiveness of the prevention of retinal detachment. Our long time follow-up studies pointed out, that regular follow-up is superfluous after posterior vitreous detachment.

Biomicroscopic method simplified preoperative examination of retinal detachment, reduced time of examination. Effectiveness of the biomicroscopic approach is particularly evident in the preoperative examination of pseudophacic retinal detachment, where our results are better, than that, published in the literature. In addition vitreoretinal examination improves our understanding of vitreoretinal pathology and produces better surgical results. Our postoperative results of the surgical management of the usually complex pseudophacic retinal detachment are similar, than the published results of the phacic retinal detachment repair.
