Intraindividual comparison between femtosecond laser-assisted and conventional cataract surgery.

Purpose: To compare the safety and efficacy between femtosecond laser-assisted cataract surgery using the Victus laser system and conventional cataract surgery.

Setting: Department of Ophthalmology, Kepler University Hospital, Linz, Austria.

Design: Prospective randomized case series.

Computer-assisted diagnosis of monocular elevation deficiency.

Our aim is to demonstrate the benefits of using a computer model to support the clinical diagnosis of complex eye motility disorders. For diagnosis and differential diagnosis we compared the clinical data of a patient with suspected monocular elevation deficiency (MED) and the corresponding computer simulation with the simulations of rectus superior palsy, vertical Duane miswiring syndrome and two simulations of asymmetric gaze palsy. We used our biomechanical eye model SEE-KID for the computer simulations, which is partly based on ideas and concepts of the software system Orbit™ by Joel Miller.

Ultrastructure and retinal imaging of internal limiting membrane: a clinicopathologic correlation of trypan blue stain in macular hole surgery.

Purpose: The purpose of this study was to correlate the ultrastructural morphology of epiretinal and retinal tissue with optical coherence tomography assessment and to investigate the effects of trypan blue staining on internal limiting membrane (ILM) tissue.

Methods: This was a prospective case-comparative study. Consecutive patients were recruited and underwent ILM peel with 0.

Ultrastructure and retinal imaging of epiretinal membrane: a clinicopathologic correlation of trypan blue staining in epiretinal membrane surgery.

Purpose: The purpose of this study was to correlate the ultrastructural morphology of epiretinal tissue with optical coherence tomography and to investigate the effects of trypan blue staining on epiretinal membrane (ERM) ultrastructure and clinical outcome.

Methods: A prospective, case-comparative study. Consecutive patients were recruited and underwent vitrectomy and ERM peeling with 0.

Idiopathic macular holes: ultrastructural aspects of surgical failure.

Purpose: To investigate the ultrastructure of the internal limiting membrane (ILM) and epiretinal tissue in eyes with idiopathic macular holes that were not successfully closed by one operation.

Methods: A second vitrectomy with en bloc removal of the ILM and epimacular tissue was performed in 16 eyes with full-thickness macular holes after surgical failure. The specimens were processed for transmission electron microscopy.

Ultrastructure of the vitreomacular interface in full-thickness idiopathic macular holes: a consecutive analysis of 100 cases.

Purpose: To evaluate the ultrastructure of the vitreoretinal interface in stage III and stage IV idiopathic macular holes.

Design: A consecutive observational case series, laboratory investigation.

Methods: Pars plana vitrectomy with en-bloc removal of the internal limiting membrane (ILM) and epimacular tissue was performed by one surgeon in 80 eyes with stage III macular holes and in 20 eyes with stage IV macular holes.

Evaluation of the internal limiting membrane after conventional peeling during macular hole surgery.

We evaluated the histologic features of the internal limiting membrane (ILM) of the retina removed during macular hole surgery without indocyanine green staining. Our investigation focused on the presence or absence of retinal structures adherent to the retinal surface of the ILM. Because only tiny retinal cellular fragments were observed especially in ILM folds, we conclude that conventional ILM peeling can be performed safely with a cleavage plane between the retinal surface of the ILM and Müller cell endfeet.

Staining and peeling of the internal limiting membrane in the cat eye.

Purpose: To investigate the cat vitreomacular interface using trypan blue (TB) and indocyanine green (ICG) and to determine the validity of the cat model in terms of staining and peeling of the internal limiting membrane (ILM).

Methods: Lensectomy and vitrectomy were performed in four eyes of two cats. The ILM of two eyes was stained with TB (0.

Epiretinal pathology of diffuse diabetic macular edema associated with vitreomacular traction.

Purpose: To investigate the ultrastructure of the vitreomacular interface in patients with diffuse diabetic macular edema (DDME) associated with vitreomacular traction.

Design: Laboratory investigation.

Methods: Fifty-five consecutive patients with DDME underwent vitrectomy with en-bloc removal of the inner limiting membrane (ILM) and epimacular tissue.

Posterior vitreous detachment induced by microplasmin.

Purpose: To demonstrate the efficacy of microplasmin in inducing posterior vitreous detachment (PVD) and to evaluate the human and the feline retina after treatment.

Methods: Thirteen human donor eyes were injected with 62.5, 125, or 188 micro g microplasmin.
