Grid laser photocoagulation for macular oedema due to branch retinal vein occlusion in the age of bevacizumab? Results of a prospective study with crossover design.

Background And Aim: To investigate the long term effectiveness of grid laser photocoagulation (GLP) versus intravitreal bevacizumab (BEV) in macular oedema (MO) secondary to branch retinal vein occlusion (BRVO), and to evaluate the treatment courses after treatments were switched.

Methods: In this prospective interventional consecutive case series, previously untreated eyes with perfused MO were enclosed over a period of 16 months for BEV and for 29 months for GLP. The follow-up period was 1 year.

[Artificial iris].

The flexible iris prosthesis according to Koch with a customized iris design serves for anterior segment reconstruction in patients with partial or complete aniridia. It is designed for implantation in the ciliary sulcus and is recommended only for pseudophakic or aphakic eyes. The multilayered implant consists of a core of a silicone matrix with incorporated color pigment coated with another layer of medical grade silicone.

Predictive factors for functional improvement after intravitreal bevacizumab therapy for macular edema due to branch retinal vein occlusion.

Background: To identify predictive factors for improvement of visual acuity and central retinal thickness by intravitreal bevacizumab for the treatment of macular edema (ME) due to branch retinal vein occlusion (BRVO).

Methods: Two hundred and five eyes from 204 patients with ME secondary to BRVO were retrospectively included at six sites. All eyes received intravitreal bevacizumab therapy (1.

[Intravitreal drug therapy for retinal vein occlusion--pathophysiological mechanisms and routinely used drugs].

The novel therapeutic principle of intravitreal drug therapy for retinal vein occlusion has become an integrated constituent of clinical practice over the last years. The two substance classes that have been evaluated in large randomised clinical trials so far are corticosteroids and inhibitors of vascular endothelial growth factor (VEGF). The reported treatment success of these intravitreally administered substances has lead not only to a paradigm shift in clinical care but has also advanced our understanding of the underlying pathophysiological principles of retinal vein occlusions.

[Bilateral tumors of the eyebrows].

We report about a 5-year-old boy who presented in our clinic with bilateral, slowly progressive solid tumors of the eyebrows. Histological examination of the excised tumors revealed the typical diversified picture of pilomatrixoma with basophilic and shadow cells. The bilateral or multiple manifestation of pilomatrixoma is uncommon and can be associated with myotonic dystrophy, sarcoidosis or Gardner's syndrome.
