[Experimental correction of irregular astigmatism in patients with keratoconus using diode laser thermal keratoplasty].

Objective: To evaluate the potential of diode laser thermokeratoplasty (DTK) in the correction of irregular astigmatism in patients with keratoconus.

Group And Methods: The coagulation of deep layers of cornea stroma was made on four eyes of four patients suffering from advanced keratoconus at the mean age of 31 years by means of the infrared contact cw laser Prolaser Rodenstock 1.9 DTK.

[Primary pars plana vitrectomy in the treatment of penetrating eye injuries involving intraocular foreign bodies in the vitreous body ].

The method of choice in the treatment of penetrating eye injuries affecting the vitreous body with an intraocular foreign body is in the majority of patients primary pars plana vitrectomy with transvitreal extraction of the foreign body (FB). During the period from April 1999 till September 2000 the authors treated thus at the Ophthalmological Clinic of the General Faculty Hospital and 1st Medical Faculty Charles University Prague 26 eyes of 26 young men with an average age of 34 years. The mean interval between the injury and primary PPV was 8.

[The retinal nerve fiber layer in glaucoma. II. The status of the nerve fiber layer and development of changes in the visual field. Prospective study].

Purpose: To determine whether retinal nerve fiber layer (RNFL) photographs can predict future glaucoma visual field damage.

Methods: In a prospective study 158 red free photographs of the RNFL were made from November 1994 to June 1995. 28 eyes of 19 patients with ocular hypertension (repeated intraocular pressure over 21 mmHg and normal visual fields--Peristat 433 Rodenstock--at first examination) could be re-examined for an average time of 42.
