Long-term results after drainage of premacular subhyaloid hemorrhage into the vitreous with a pulsed Nd:YAG laser.

Objective: To investigate the effects of drainage of premacular subhyaloid hemorrhage into the vitreous with an Nd:YAG laser in a large series of patients with long-term follow-up.

Methods: A retrospective review was conducted on 21 eyes with a circumscribed premacular subhyaloid hemorrhage of various causes. These eyes were treated with a pulsed Nd:YAG laser to drain the entrapped blood into the vitreous.

[Risk factors for surgical failures in rhegmatogenous retinal detachment].

Background: The evaluation of further risc factors predesposing failure in retinal detachment surgery than those already known to be associated with PVR was the goal of this retrospective study.

Patients And Methods: The data from 130 cases with unilateral rhegmatogenous retinal detachment treated initially with buckling procedures, were retrospectively reviewed to investigate pre-, intra- and postoperative factors which may predispose anatomical failure in retinal detachment surgery. None of the selected consecutively operated eyes had risk factors, which have already been associated with an unfavourable outcome, such as the presence of preoperative macular holes, PVR or assumed PVR-inducing factors, such as ocular trauma, giant retinal tears, vitreous hemorrhage, previous vitrectomy, cryopexy and laser photocoagulation.

[Automated flicker perimetry].

Flicker fusion frequency (FFF), the threshold criterion of flicker perimetry, is a functional parameter of the temporal transfer properties of the visual system. An automated flicker perimeter suitable for clinical routine purposes is presented that allows perimetric examination of the central visual field with high spatial resolution. The intent of the present study was to investigate the outcome of flicker perimetry in comparison to static light-sense perimetry.
