Recommendations for ultrasound examination in ophthalmology. Part II: Orbital ultrasound.

Pathological processes within the orbits are a heterogeneous group of diseases of various etiologies, clinical pictures and therapy models. Due to poor access to the orbits in a clinical examination, imaging plays a significant role in both diagnosis and treatment monitoring in patients with an orbital pathology. One of such imaging modalities is ultrasonography.

Observations on degenerative changes within the optic nerve in patients with primary open glaucoma and arterial hypertension: 6-month follow-up.

The authors aimed to determine the effect of the time of hypotensive drug administration on the progress of degenerative changes within the optic nerve in patients with hypertension and glaucoma. Two groups were included in the study: group A comprised patients-dippers taking drugs in the mornings, and group B comprised patients-nondippers taking drugs both in the mornings and in the evenings. After 6 months, group B showed significant drops in nocturnal diastolic blood pressure (BP) (month 1=73.

Effects of the time of antihypertensive drugs administration on the stage of primary open-angle glaucoma in patients with arterial hypertension.

Many patients with glaucoma suffer from arterial hypertension (AH). It has been proved that both AH and low blood pressure (BP) at night are important vascular risk factors for primary open-angle glaucoma (POAG). The aims of this study were to assess the severity of pathological changes within the optic nerve and characteristics of blood flow in selected arteries of the eyeball and orbit in patients with POAG and controlled hypertension, in relation to the time of hypotensive drugs administration.

A marked fall in nocturnal blood pressure is associated with the stage of primary open-angle glaucoma in patients with arterial hypertension.

Introduction: The aim of this study was to assess blood flow in the vessels of the eyeball and changes in the optic nerve in patients with arterial hypertension and primary open-angle glaucoma.

Material And Methods: The patients were divided into groups: 1 (night blood pressure, BP, fall, NBPF, not more than 10%; non-dippers); 2 (NBPF 10-15%, dippers) and 3 (NBPF>15%; extreme dippers).

Results: In the group of dippers and extreme dippers, perfusion pressure was significantly lower than that in the non-dippers group, there was reduced thickness of the nerve fibers and a greater decrease in the visual field.

[Surgical management of thyroid orbitopathy].

Thyroid orbitopathy (TO) requires often not only pharmacological treatment but also surgical procedures. The management contains orbital decompression (wall decompression, excision of fat), correction of lid retraction and strabismus operations on extraocular muscles. Authors describe indications for surgical procedures, methods of operations, results and complications of own material of 99 patients with TO treated in the Eye Clinic in Poznan and Plastic Surgery and Eye Clinic in Kobylniki from 1999 until 2003.

[Glaucoma and ocular ischemic syndrome--case report].

Purpose: Ocular ischemic syndrome (OIS) is often poorly diagnosed and treated as primary open angle glaucoma or later on, as neovascular glaucoma. We present a 54 year old male, treated topical since 23 years for glaucoma and sent to our clinic for trabeculectomy because of rapid worsening of vision on right eye with bilateral total excavation of optic disc.

Material And Methods: Observational case report.
