Symmetry of retinal vessel arborisation in normal and amblyopic eyes.

Purpose: Arborisation of retinal vessels might be influenced by the physiological activity of the retina. It seems that the pattern of retinal vessels is an obvious object for fractal analysis. The fractal dimension of normal retinas was therefore used by us as a control value for comparison with the values collected from patients with amblyopia in one eye connected with strabismus and normal vision in the other.

[Neuro-hormonal regulation of aqueous humor dynamics as the basis of glaucoma pharmacotherapy. Part II - Aqueous humor outflow].

The aim of this article is to present current opinion on aqueous humor dynamics regulation and antiglaucoma drugs mechanisms of action. Pharmacotherapy of glaucoma is based mainly on neuro-hormonal processes controlling aqueous humor dynamics. Systemic hormones as well as local hormones and autonomic nervous system mediators are involved in the processes of aqueous humor formation and drainage.

[Intraocular lens power calculation in patients after keratorefractive surgery--personal experience].

Purpose: To assess the efficacy of intraocular lens power calculation in patients with previous corneal refractive surgery.

Material And Methods: Retrospective analysis of patients after laser refractive procedures, in whom cataract removal with phacoemulsification method was performed. Corneal power, which in conventional measurements after refractive surgery tends to increase value and results in postoperative hyperopic shift, were calculated with five methods, and the results were compared.

Osteoinductive properties of urothelium depend on inherent bone morphogenetic proteins (BMPs).

Background: The mechanism of heterotopic ossicle formation induced by grafted transitional epithelium, described in several species, has not yet been elucidated. This phenomenon is not species specific, but in xenogeneic systems, immunosuppression of the host is needed to protect the implant long enough for it to exert its osteoinductive potency. We showed a strong correlation between the intensity of bone induction caused by implantation of HeLa cell lines and their ability to synthesize and secrete seven different isoforms of BMPs (bone morphogenetic proteins).

[Phacoemulsification combined with trabeculectomy from personal material].

Aim: The aim of the study was to establish the efficiency of phacoemulsification combined with trabeculectomy in patients with cataract and glaucoma.

Material And Methods: 102 patients (112 eyes) with cataract and glaucoma, who were operated between 1998 and 2001. The follow up time--from 6 month to 3 years.
