In a retrospective study we analyzed the records of 18 patients with pseudophakic retinal detachment. Cataract operation had been performed by extracapsular (n = 14) and intracapsular procedures (n = 6). In 14 of 18 cases, intra- or postoperative complications preceded the retinal detachment: capsular rupture with vitreous loss and anterior vitrectomy during cataract operation (n = 5), vitreous wick (n = 5), and explantation of the intraocular lens because of chronic intraocular inflammation (n = 3). At the time of admittance for retinal surgery, 14 patients (78%) had a detached macula. In 8 cases (44%), proliferative vitreoretinopathy had developed. In 17 of 18 cases (94%), the retina could be reattached by buckling procedures alone or combined with vitrectomy and SF6 or silicone oil tamponade. The risk of retinal detachment in pseudophakic eyes should be reduced by careful anterior vitrectomy in cases of vitreous prolapse and vitreous wick or by avoiding lens implantation in complicated cataract operations.

A prospective study was carried out to estimate the incidence and severity of ptosis following cataract extraction and trabeculectomy. A postoperative ptosis of 2 mm or more was found in 6.2% of all cases. In this series the incidence of ptosis following surgery under local anaesthesia was greater than that under general anaesthesia. The aetiology and management of this complication are discussed.

A new method for removing a secondary cataract with a posterior chamber lens in situ was developed using a specially designed irrigation/aspiration handpiece. In two cases, a focal rupture of the posterior capsule without vitreous prolapse occurred. There were no other serious complications observed in 367 patients who were treated.

Since optometrists are becoming more involved with postoperative cataract care and the often associated traumatic ptosis, a comprehensive discussion of ptosis, including its etiology, classification as either congenital, acquired, or pseudoptosis, and evaluation, is presented. Referral situations and management strategy are discussed. To illustrate these points, a case of transient acquired ptosis is reviewed.

In 163 children (256 eyes), aged from 3 months to 14 years, with different clinical forms of bilateral and monolateral congenital cataracts surgical interventions were used. A new method of extracapsular cataract extraction is described: as a retractor and protector of the iris in the performance of the operation, a formed flap of the anterior lens capsule is used. The proposed method provides conditions for maximum and atraumatic removal of masses from the upper segment of the lens capsule, lowers the risk of the opening of the posterior capsule, prolapse of the vitreous body and prevents traumatizing of the iris. Optical results depended on the kind of cataract and the presence of associated pathology. Visual acuity of 0.3-1.0 was achieved in 37.1%-46.4% in zonular cataracts and in 21.7%-22.2% in total cataract. In case of atypical congenital forms of cataract it was, as a rule, not higher than 0.2.

Traumatic blepharoptosis, although considered relatively rare, is an entity which demands recognition if one is to achieve optimal results. Reports of levator injury following orbital, ocular, and adnexal surgery, as well as in cataract and blepharoplasty procedures, are well described. In most cases eventuating in complete ptosis, levator disinsertion is the anatomic correlate, the ptosis is usually permanent, and surgical intervention is often indicated. We have observed two cases of transient, complete post-traumatic ptosis which have recovered by 6 weeks with expectant management. We believe this entity to be more pervasive than the current literature seems to reflect and emphasis is placed on nonoperative therapy. This paper reviews the anatomical considerations relevant to the function of the levator complex as well as the possible mechanisms for its injury.

In a series of 11 pseudophakic patients (11 eyes) who sustained wound dehiscence as a result of blunt trauma, five intraocular lenses were dislocated, one was fractured, and two were expulsed. Wound rupture occurred from three days to one year after surgery; the most common cause of injury was a fall. Iris prolapse was observed in all patients, with hyphema observed in seven. Vitreous prolapse occurred in four patients, and three patients developed retinal detachment. Six of the 11 patients had a visual acuity of 20/40 or better after repair. The limbal wound of a pseudophakic eye can dehisce as a consequence of blunt trauma long after surgery, and the position of the intraocular lens can be disrupted. Patients undergoing cataract extraction with intraocular lens implantation should be advised about the importance of long-term protective eyewear.

This book contains various illustrations, portraits and an exact index, testimonials proving the author's professional successes as well as an accurate list of the qualities that should be demanded from any ophthalmologist. The anatomy of the head and eye is described according to Galen's ideas and Vesalius' book. Many remedies, prescriptions and medical treatments are discussed, partly showing the mystic influences of the Middle Ages. Bartisch reports several diseases for the first time: Allergic reactions, sympathetic ophthalmia, hemeralopia, photoelectric keratoconjunctivitis, amaurosis due to toxemia of pregnancy. But most important is the part on surgery. A careful pre- and postoperative treatment is demanded in cases of cataract operations. Bartisch describes the removal of eyelashes to cure trichiasis, the operations of ptosis, blepharochalasis and the exenteration of the orbit. This book was appreciated for a long time so that in 1686 a nearly identical reprint was published.

In the last five years, 500 one-eyed patients have undergone cataract surgery at the authors' hospital. A Simcoe-type posterior chamber lens was implanted in 425 of the eyes. An eye was defined as an only eye if corrected vision in the fellow eye was 1/60 or less, or better vision in cases of amblyopia. The main causes of loss of function in partner eyes were macular degeneration, amblyopia, and glaucoma. The rate of intraoperative and postoperative complications was the same as in the entire patient collective, and in absolute terms actually lower. There were four cases of intraoperative rupture of the posterior capsule (in two of which it subsequently proved possible to fit a posterior chamber intraocular lens (PCIOL], and one case each of corneal decompensation and excessive hemorrhage into the anterior chamber. PCIOLs were subsequently also implanted in both these eyes. Early postoperative complications included several cases of iris prolapse, all of which were easily rectified, and intermittent phases of endothelial decompensation associated with cornea guttata. In view of the low overall rate of intraoperative and postoperative complications, the authors advocate implantation of a PCIOL in remaining eyes with visual function, except those with proliferative retinopathies (primarily diabetes mellitus), pre-existing retinal detachments (particularly in young men with myopia and a history of detachment in the fellow eye), and unregulated glaucoma.

An 87-year-old woman, who had undergone cataract surgery and vitrectomy OD two years previously, had a blind, painful right eye secondary to intraocular hemorrhage and glaucoma. At the initial examination, a flat area of darkly pigmented tissue was noted at the wound site of the previous cataract surgery, and uveal prolapse was diagnosed. One year later, pigmented tissue was also seen at the inferior limbus. Intraocular malignant melanoma was considered, and the eye was enucleated. Histologic study revealed areas of hemorrhage and epithelioid malignant melanoma. It is important to recognize that prolapse of tissue at a surgical wound site may represent an extension of an intraocular malignancy.
