In facial hemiatrophy two different types are known: the progressive acquired type, which is relatively more common, and the rare congenital non progressive form. Two children--both with congenital facial hemiatrophy--are presented, both showed a (horizontally and vertically) smaller lid fissure and antimongoloid configuration of the lid. In addition in one case we could observe: small corneal diameter, staphyloma posticum, paving stone degeneration of the retina, convergent strabismus, and vertical deviation, in the other case: ptosis, major astigmatism, and latent divergent strabismus.

We present a modified self-sealing wound construction with a trapezoidal incision for No-Stitch-Technique. Due to the form of the incision and the elasticity of the sclera the 6 mm incision can be extended to about 8 mm which allows an implantation of conventional PMMA-IOL without excessive scleral stretching. Since the beginning of 1991 this technique has been used routinely in our clinic with over 1500 operations. The No-Stitch-Technique has, in comparison to the sutured corneo scleral incision, two main advantages: the wound closure has a five fold higher stability and an induced astigmatism of less than 1.0 dpt. Other postoperative complications, such as wound dehiscence, iris prolapse and hypotony syndrome, were significantly eliminated.

An 8-year-old boy with congenital ptosis of the right upper eyelid due to plexiform neurofibroma was operated on because of a rapidly worsening of his ptosis. Only partial removal of the tumor was possible. A hypermetropic astigmatism of the right eye was caused by the condition of the upper lid, with secondary amblyopia. This finding suggests that in cases of congenital ptosis the presence of a lid tumor must be suspected. Such a tumor causes ptosis and this can lead to refraction error and amblyopia.

In 1978 at the beginning of the modern lens implantation era, 6160 posterior chamber lenses (PCL) were implanted in the USA; 1,110,000 PCL were implanted in 1986. With reference to the total number of lenses implanted, PCL implantations amounted to 4% in 1978 and to 89% in 1986. The increasing use of PCL has mainly been due to the fact that patients with these lenses had significantly better visual acuity and fewer complications after surgery than patients with anterior chamber lenses (ACL). As an example, an FDH study in 1983 should be mentioned: more vision in an otherwise normal eye was more than 0.5: 90% (ACL) versus 94% (PLC); ablatio: 0.9% versus 0.5%; secondary glaucoma: 1.2% versus 0.5%; cystoid edema of the macula: 2.2% versus 0.8%. The considerable advantage in extracapsular extraction of a cataract lies in the fact that the anatomical and physiological conditions of the eye structure may be nearly completely maintained, and this is because the intact posterior capsule--similar to the lens with zonular fibers in the normal eye--forms a diaphragm between the vitreous and aqueous humor. Thus the stability of the eye will be maintained and prolapse of the vitreous with possible traction at the retina cannot occur. Phacoemulsification and ECCE are well-established methods. The clinical results of both methods are practically identical, except for a significantly lower rate of astigmatism with phacoemulsification, which was examined 8 to 10 weeks following surgery (phaco: 1.0 +/- 0.49; expression: 3.3 +/- 1.7).(ABSTRACT TRUNCATED AT 250 WORDS)

In a new surgical procedure, adverse reactions or complications may surface without most ophthalmic surgeons experiencing them or being aware of them. Even those with a large series of cases may never see certain problems. Through a collaborative effort with over 200 radial keratotomy surgeons totaling 63,000 cases nearly every significant complication has been documented. This study of radial keratotomy complications includes the number of patients and percentage of the total of the following: intraoperative occurrences which generally do not affect vision, which include microperforations and macroperforations; postoperative changes which do not affect vision: limbal "peeking" and star pattern with light; transient occurrences which tend to resolve with time: ptosis, recurrent erosions, corneal ulcer, microwound abscess, delayed wound healing, inferior rectus palsy, glare or fluctuating vision after six months, iritis, and stromal keratitis; postoperative changes which can affect vision (correctible): overcorrection more than 1.5 diopters, marked undercorrection more than -2.00 diopters, irregular astigmatism, neovascularization after soft-contact-lens wear, and best-corrected acuity decreased usually only one line; and postoperative changes which can affect vision (uncorrectible): retrobulbar hemorrhage and endophthalmitis, loss of the eye, herpes keratitis, and cataract formation.

An 18-month-old girl presented with the ocular findings of severe ptosis of the right upper lid, astigmatism and the Adduction Fixation Preference. She also had psychomotor retardation and multiple congenital anomalies. The karyotype revealed an interstitial deletion of the long arm of chromosome 5 at q 12. This is the first description of the ophthalmological findings in this chromosomal disorder.

Fifty-four consecutive surgical cases of congenital ptosis were carefully evaluated to determine the incidence of refractive errors, strabismus and amblyopia. Of these patients, 70% had a refractive error, 43% had an astigmatism of more than 1.0, 55% had anisometropia, 27.5% had concomitant squint and 50% amblyopia.

Of 122 patients with corneoscleral lacerations repaired during a four-year period, 21 (17%) underwent enucleation primarily or within ten days of injury, 85 (70%) had at least six months of follow-up, and 16 (13%) were unavailable for follow-up. The most significant predictors of enucleation were poor initial visual acuity, the amount of hyphema, the presence of posterior uveal prolapse or vitreous hemorrhage, the extent of lens damage, and the length of laceration. The most significant predictors of a good visual outcome were good initial visual acuity, absence of hyphema, absence of posterior uveal prolapse or vitreous hemorrhage, and length of laceration. Final astigmatism was greater if the corneal wound was 4 mm or longer. Delaying the initial repair up to 36 hours had no effect on outcome.

In seven patients with intracranial meningioma whose presenting signs and symptoms were ophthalmologic the underlying problem was initially misdiagnosed. Three patients had sphenoidal meningiomas with compression of the anterior visual pathways, but the initial diagnoses were acute optic neuritis, chronic optic neuritis and glaucoma. Two other patients had large frontal meningiomas causing in one case unilateral pain and swelling of the upper lid plus ptosis and hypotropia, and in the other case bilateral frontal morning headaches and intermittent blurring of vision in one eye; they were thought to have a frontal lobe osteoma and migraine respectively. A sixth patient had a large parietal meningioma causing unilateral papilledema in an eye with a corneal graft; the papilledema was not initially recognized because of severe astigmatism in that eye. The last patient had an occipital meningioma that had caused a fixed homonymous field defect and many years of "classic migraine".

We present of modified technique for sutureless ECCE with a trapezoidal tunnel incision of 11 mm. The operation can be performed in a closed system because of the self-sealing wound construction. Compared to the sutured corneoscleral ECCE the new procedure has important advantages: the procedure is safe even during the critical phase following nucleus extraction. The procedure is therefore safer, faster, more economical and suture-induced astigmatism is avoided. Clinical experience after 2 years showed that postoperative complications were reduced significantly. Iris prolapse, wound dehiscens and hyphema occurred at a rate of 2%. The astigmatism (Jaffe analysis) was at a rate of 2 D, stable within 4 weeks after surgery, and did not change up to 2 years postoperatively. The astigmatism induced was then reduced about 0.5 D by a radical suture.
