[Confocal laser scanning tomography (HRT) in diagnosis and monitoring glaucomatous optic nerve damage in primary open angle glaucoma].

Purpose: The aim of this study was to estimate HRT usefulness in quantitative evaluation of structural glaucomatous optic nerve head damage and in monitoring this atrophy in POAG patients and normal subjects, during 18-monthly follow up.

Material And Methods: 130 eyes of 84 patients with primary open angle glaucoma, 52 women (79 eyes) and 32 men (51 eyes) in age 45-70 (mean = 54.69 yrs) and 96 eyes of 48 normal subjects, 33 women (66 eyes) and 15 men (30 eyes) in age 40-70 (mean=51.

A unique case of primary corneal melanoma.

Purpose: To report a unique case of primary corneal melanoma.

Methods: A 59-year-old white woman underwent keratectomy to remove a pigmented rapidly enlarging growth on the corner of her left eye. The specimen was submitted for histopathologic examination.

[A grid pattern type of photocoagulation in treatment of diabetic maculopathy--personal experience].

Purpose: The aim of the present study was the evaluation of visual outcome of 425 eyes in 283 patients treated by focal and grid pattern photocoagulation for clinically significant macular edema according to the recommendations of the Early Treatment Diabetic Retinopathy Study (ETDRS).

Material And Methods: On the basis of baseline status of macula, eyes were classified into three groups: group I--eyes treated by focal photocoagulation (39 eyes), group II--eyes treated by focal photocoagulation and/or modified grid (84 eyes), group III--eyes treated by focal photocoagulation and/or grid pattern (302 eyes). Eligibility criteria for this retrospective study included a diagnosis of clinically significant macular edema according to the ETDRS scale.

[Valve implants of glaucoma pressure regulator for refractory glaucoma: own experience].

Purpose: To present our experiences in valve implantation for refractory glaucoma.

Material And Methods: From October 1993 to December 1996 implantations of Glaucoma Pressure Regulator Optimed were performed in 7 eyes of 7 patients. There were 4 men and 3 women aged from 32 to 65 years.

[Keratectomy for a malignant melanoma of the cornea].

Purpose: To present the possibility of malignant melanoma treatment of the cornea using keratectomy.

Material And Methods: A 59-year old woman with a primary malignant melanoma of the cornea. Visual acuity before surgery 0.

[The evaluation of the usefulness of phacotrabeculectomy as the only surgery for glaucoma and cataract patients].

Purpose: To evaluate IOP changes after phacotrabeculectomy.

Material And Methods: 24 glaucoma patients (27 eyes) with coexistence of cataract. Age: 56-79 years.

[Activity of selected enzymes of the anti-oxidase system in the vitreous body, aqueous humor and lens after subconjunctival ozone in experiments].

The influence of ozone on the activity of enzymes of the antioxydation system in selected structures of the eye were checked. Ozone given topically in weak concentrations acts stimulating, increasing the activity of the enzymes of the antioxydation system, instead in high concentrations causes a significant reduction of activity of the enzymes of the mentioned system.

[Hemodilution in the treatment of central retinal vein thrombosis].

The authors present contemporary opinions on the aetiology, forms and prognosis in central retinal vein occlusion. Methods of treatment by haemodilution, indications and contraindications are discussed.
