[A triple operation of perforating corneal transplantation, cataract extraction and implantation of an intraocular lens].

The triple operation was performed in 7 patients (4 men and 3 women). The age of the patients was 18-56 years, the period of hospitalization 3 to 5 days. The surgery was performed in a light intravenous anaesthesia (NLA) or topical anaesthesia. The diameter of the graft oscillated between 7.25 and 9.0 mm. In all the cases after an extracapsular cataract extraction (or removal of remnants) the lens was implanted in the capsule. The graft was sutured by means of 20 single stitches (10.0 nylon) or applying a continuous suture (11.0 nylon). From the complications one observed breaking of a stitch, vascular ingrowth from the periphery and glaucoma. In the postoperative period--from 9 months to 3 years the visual acuity of the patients improved up to 0.4-0.7 in 4 cases and up to 0.8-1.0 in the remaining 3 cases.

[Disintegration of the cornea requiring total grafting in a case of acute gonorrhea infection].

Presented is a case of an acute gonorrhea infection of the eye with disintegration of the cornea which required a nearly immediate operation of corneal transplantation "from limbus to limbus". The patient, aged 17 years was admitted to the hospital showing bilateral acute purulent conjunctivitis and central necrosis of the left cornea with suspicion of endophthalmitis. In spite of a massive pharmacological treatment (together with intravitreal cephazolin) the cornea disintegrated from hour to hour. In atypical conditions, in an eye with acute inflammation a corneal grafting was performed together with cataract extraction and anterior vitrectomy. The grafting was "from limbus to limbus". The visual acuity of the eye with transplantation improved--with correction of +10.0 Dsph up to 1.0 in the period of 3 months.

[Optic nerve microcirculation. III. Lamina cribrosa].

The architecture of the lamina cribrosa was investigated on the material of 160 optic nerves of people decreased at the age of 6 months to 80 years, free of pathological changes of circulation. The posterior segment of lamina cribrosa is supplied by arterial blood from: centripetal arterioles of the pia mater, ramifications from the secondary and tertiary posterior short ciliary arteries and from the longitudinal net of capillaries of the optic nerve. The central part of the lamina cribrosa is supplied by the twigs of the complete or incomplete vascular ring of Zinn-Haller or directly from secondary twigs of choroidal arteries. The anterior part of lamina cribrosa is vascularized by choroidal vessels and in a minor part by the vascular ring of Zinn-Haller. The circulation in the area of lamina cribrosa is integrally connected with the system of posterior short ciliary arteries and the arterioles of the internal vagina of the optic nerve. The central retinal artery does not give up any branches in this region. Similarly to other segments of the optic nerve there exists an individual variability in the system and course of the vessels in the lamina cribrosa. The vascular system of lamina cribrosa is connected anteriorly with the vessels of the paralaminar area of the optic disc which receive vascular branches from early ramifications of the central retinal artery (25 p.c. of cases).
