[Guidelines for ophthalmological screening of premature infants in Germany].

These revised guidelines replace the previous guidelines on the screening of preterm infants for retinopathy of prematurity (ROP) that were published in 1999. Recently published research provided the impetus for this revision. These guidelines propose the following criteria for an efficient screening programme for the early detection and treatment of ROP in Germany: Inclusion criteria for ROP screening: All preterm infants with a gestational age of less than 32 weeks (if gestational age is unknown; of <1500 g birth weight) should be examined.

[Wide angle fundus documentation in retinopathy of prematurity].

Background: Fundus documentation in preterm infants has been improved by the advent of a new wide-angle fundus camera (RetCam 120).

Patients And Methods: In 30 preterm infants we used the RetCam 120 for retinopathy of prematurity (ROP) screening, before and after laser treatment of ROP and after regression of acute phase ROP for documentation of fundus findings. The RetCam 120 is a digital contact wide-angle fundus camera which is based on a 3-chip CCD video camera.

[Transscleral and transpupillary laser coagulation in proliferative sickle-cell retinopathy].

Background: Transscleral diode laser photocoagulation is a new method for treating proliferative sickle-cell retinopathy (PSR). Other treatments include transpupillary laser photocoagulation and transscleral cryocoagulation

Case Report: We report two patients with sickle-cell disease and PSR, one treated by transpupillary argon laser coagulation and the other by transscleral diode laser scatter photocoagulation.

Conclusion: Transpupillary and transscleral laser photocoagulation are effective and safe in the treatment of PSR.

Merkel cell carcinoma of the eyebrow extending into the orbit.

Background: Merkel cell carcinoma is a rare and aggressive cutaneous neoplasm with high local recurrence and metastatic rates.

Purpose: To highlight an unusual presentation of a Merkel cell carcinoma.

Case Report: We report a large Merkel cell tumor in an 85-year-old woman.

[Acute retinpathia praematurorum. Is plasma prorenin level of prognostic value?].

Background: In patients with diabetes mellitus an elevated level of plasma prorenin (PP) may be associated with proliferative diabetic retinopathy. Although retinopathy of prematurity (ROP) is also characterized by retinal vasoproliferation, no study on PP in ROP appears to have been carried out. This study investigated PP prospectively in preterm infants with high risk of ROP.

Risk factors in retinopathy of prematurity. a multivariate statistical analysis.

[Trans-scleral diode laser coagulation for therapy of acute retinopathia praematurorum].

Background: Lens opacities were noted in single cases after transpupillar laser photocoagulation in retinopathy of prematurity (ROP) using the laser indirect ophthalmoscope. The diode laser with its wavelength in the near infrared (810 nm) makes lens sparing transscleral retinal coagulation possible.

Patients And Methods: In a controlled clinical study 60 eyes of 30 very low birth weight infants (gestational age 23-31 weeks, mean 26.

Trans-scleral diode laser photocoagulation in proliferative sickle cell retinopathy.

Objective: To demonstrate the feasibility of trans-scleral diode laser photocoagulation for the treatment of proliferative sickle cell retinopathy.

Design: Interventional case report.

Intervention: Trans-scleral diode laser scatter photocoagulation was applied to both eyes of a 30-year-old man with hemoglobin SC disease.

[Computer program for retinopathy of prematurity screening].

Background: The goal of retinopathy of prematurity (ROP) screening is complete detection of all preterm infants with threshold ROP.

Aim: We wanted to develop software to facilitate registration of ROP findings, checking due dates of re-examination, and evaluation of screening data. By means of complete and faultless registration and evaluation of the data of preterm infants, the effectiveness and safety of the screening should increase.

Laser in situ keratomileusis for moderate and high myopia and myopic astigmatism.

Objective: This study evaluated the predictability, stability, and safety of laser in situ keratomileusis (LASIK) in myopia and myopic astigmatism.

Design: The study design was a prospective, unmasked, nonrandomized clinical trial.

Participants: Participating were 25 patients with myopia (37 eyes) with astigmatism of less than 1.

[Laser in situ keratomileusis (LASIK) for correction of myopia].

Background: Laser in situ keratomileusis (LASIK) preserves the corneal epithelium and Bowman's layer, which theoretically minimizes corneal scarring. We, therefore, evaluated the accuracy, stability and safety of LASIK in moderate to high myopia.

Patients And Methods: Eighty-five eyes (50 patients) treated using the Automatic Corneal Shaper and the Keracor 116 excimer laser were followed up for 1, 6, and 12 months.

Transscleral vs transpupillary diode laser photocoagulation for the treatment of threshold retinopathy of prematurity.

Objective: To evaluate the efficacy and safety of transscleral diode laser photocoagulation for the treatment of threshold retinopathy of prematurity (ROP).

Patients: Fifty eyes of 25 preterm infants (birth weight, 510-1200 g [864+/-178 g ¿mean+/-SD¿]; gestational age, 24-29 weeks [26.7+/-1.

Laser in situ keratomileusis to correct myopia of -6.00 to -29.00 diopters.

Background: Photorefractive keratectomy can cause corneal scarring and visual loss in highly myopic eyes. We evaluated laser in situ keratomileusis (LASIK) because it has the theoretical advantage of preserving both the corneal epithelium and Bowman's layer.

Methods: In a prospective study, LASIK was performed in 62 myopic eyes (42 patients) using the Automatic Corneal Shaper (Chiron Vision) and the Keracor 116 excimer laser (Chiron Technolas).

[Correction of myopia using laser in situ keratomileusis (LASIK)].

Background: In contrast to photorefractive keratectomy (PRK), the corneal epithelium and Bowman's layer are preserved in LASIK. Thus, there should be less scarring and regression after LASIK than after PRK.

Patients: Between December 1993 and October 1995, we treated 113 eyes (66 patients).

[Diode laser coagulation of stage 3+ retinopathy of prematurity].

Background: Laser photocoagulation in retinopathy of prematurity (ROP) appears to have fewer adverse effects and to be at least as effective as cryotherapy.

Methods: To evaluate the efficacy and safety of diode laser photocoagulation we examined 50 eyes affected by stage 3+ ROP in 30 very low birth weight infants (gestational age 24-29 weeks, mean +/- SD 26.5 +/- 1.

[The True-Vista bifocal intraocular lens. Current results of the European multicenter study].

In a prospective multicenter study we evaluated vision with the True Vista bifocal IOL. At 12-14 months after operation. 391 patients ("best cases") were available for follow-up.

[Vector analysis of surgically-induced astigmatism in cataract operation with 4 tunnel incision techniques].

Unlabelled: Evaluation of astigmatism induced by cataract surgery requires the calculation of surgically induced astigmatism using vector analysis. This method was performed for four tunnel-incision techniques and compared with the results of computer-assisted videokeratoscopy.

Methods: Phacoemulsification with IOL implantation was performed in 59 eyes using four different incisions (4- or 5- to 6-mm scleral tunnel and 4- or 5.

Bifocal intraocular lenses (BIOLs) reduce image contrast. We measured contrast sensitivity (CS) to evaluate the clinical significance of the loss in image contrast. Four groups were compared: 15 patients with a monofocal IOL, 13 with the True Vista BIOL, 13 with the AcuraSee BIOL, 11 with the diffractive BIOL.

Methods: To evaluate the efficacy and safety of diode laser photocoagulation, we included 42 eyes with stage 3+ ROP of 24 preterm infants (gestational age 24-29 weeks, mean +/- SD 26.6 +/- 1.

Diode laser photocoagulation for threshold retinopathy of prematurity in eyes with tunica vasculosa lentis.

Purpose: To determine possible side effects of diode laser photocoagulation for threshold retinopathy of prematurity in eyes with tunica vasculosa lentis.

A controlled clinical trial of light and retinopathy of prematurity.

Bright continuous light has been implicated in the pathogenesis of retinopathy of prematurity. To investigate the influence of light on the incidence and severity of retinopathy of prematurity, we enrolled 127 preterm infants (birth weight < or = 1,500 g; gestational age < or = 32 weeks) in a controlled clinical study. Randomization was done separately for three birth-weight groups (< 1,000 g; 1,000 to 1,249 g; 1,250 to 1,500 g).
