Bilateral crystalline corneal deposits as first clinical manifestation of monoclonal gammopathy: a case report.

Aims: To report the clinical and diagnostic findings of a patient with bilateral corneal deposits caused by an underlying monoclonal gammopathy.

Methods: Slit-lamp biomicroscopy, confocal microscopy and additional serological tests were performed on a 35-year-old man presenting with bilateral crystalline corneal deposits.

Results: The patient was diagnosed as having monoclonal gammopathy based on elevated levels of serum immunoglobulin G.

[A comparison between absorbable and non-resorbable scleral implants in deep sclerectomy (T-Flux and SK-Gel)].

Background: The intraocular pressure (IOP) lowering effects of deep sclerectomy (partially combined with phacoemulsification) with different scleral implants (T-Flux- or SK-Gel) were investigated.

Patients And Methods: In a retrospective study, 72 patients with medically uncontrollable glaucoma underwent non-penetrating deep sclerectomy. Of these, 54 patients received T-Flux implants and 18 SK-Gel implants.

Compromised autoregulatory control of ocular hemodynamics in glaucoma patients after postural change.

Purpose: The autoregulatory control of retrobulbar blood flow in response to postural challenge was investigated in normal-tension glaucoma (NTG) patients in comparison with primary open-angle glaucoma (POAG) patients and healthy volunteers.

Design: Prospective cohort study.

Participants And Controls: Twenty POAG patients, 20 NTG patients, and 20 control subjects.

Glaucoma progression is associated with decreased blood flow velocities in the short posterior ciliary artery.

Background: An altered perfusion of the optic nerve head has been proposed as a pathogenic factor in glaucoma.

Aim: To investigate potential differences in the ocular haemodynamics of patients having glaucoma with progressive versus stable disease, as well as healthy volunteers.

Methods: Peak-systolic velocity (PSV), end-diastolic velocity (EDV) and resistivity index in the short posterior ciliary artery (SPCA), central retinal artery (CRA) and ophthalmic artery were recorded in 114 consecutive patients having glaucoma with an intraocular pressure (IOP) < or =21 mm Hg, as well as in 40 healthy volunteers, by colour Doppler imaging (CDI).

Volumetric colour Doppler imaging: a useful tool for the determination of ocular blood flow in glaucoma patients?

Purpose: Disturbed ocular haemodynamics are discussed to contribute to the pathogenesis of glaucoma. Up to now there is no method available allowing direct determination of blood flow, which is the most relevant dimension for studies on haemodynamics. In this study, volumetric colour Doppler imaging (vCDI) is evaluated systematically in glaucoma patients.
