Pterygium consists of epithelium of bulbar conjunctiva and hypertrophied subconjunctival connective tissue. Although described and recognized before 1000 B. ⋯ Generally it is considered to be a cause of corneal blindness. The methods of pterygium surgery changes from the simplest bare sclera excision to stratified keratoplastics and transplantation technique.

At present, cataract extraction offers great improvement for uncorrected and best corrected visual acuity and rapid postoperative rehabilitation. Cataract surgery is now treated as refractive surgery. ⋯ Postoperative astigmatism is a very complex clinical problem. The main influence on its appearance has preoperative astigmatism as well as shape and length of anterior chamber opening, suturing technique and wound healing.

Historical Article
[Historical outline of deveopments in ophthalmic anesthesiology].
The history of ophthalmic anesthesiology is closely related to the development of ophthalmology. Specific needs during ophthalmic procedures bring about on further improvement of effectiveness of local and general anesthesia, since both methods are in use for ophthalmic surgery. It is hard to decide, which one is the better and more suitable for the patient, as well as the surgeon. Individual choice adequate to the certain patient and certain clinical image requires close cooperation between ophthalmic surgeon and anesthesiologist.

The aim of the paper was to assess the effect of surgical extracapsular cataract extraction with implantation of posterior chamber lens on the normalisation of intraocular pressure in eyes with glaucoma. The relationship between the preoperative depth of the anterior chamber and the postoperative normalisation of intraocular pressure was also investigated. The study was carried out on 138 eyes with cataract and glaucoma. ⋯ Nine months after the operation in 64 patients (46.3%) there was no need for giving pressure reducing drugs. The highest percentage of patients who did not require treatment (73.2%) was among eyes with closing-angle glaucoma with the smallest depth of the anterior chamber before operation. It seems that the measurement of the anterior chamber depth before the operation in patients with cataract and closing-angle glaucoma may be only the indication whether the cataract extraction with the implant of the lens is sufficient to normalize the intraocular pressure.

To evaluate the parameters of blood flow in orbital arteries of patients with traumatic optic neuropathy. ⋯ Colour Doppler ultrasonography is a useful supplementary method in diagnostics of traumatic optic neuropathy. The Colour Doppler findings seem to correlate well with clinical pathologies of the optic nerve after its traumatic injury.
