Epikeratophakia for keratoconus was done in 11 mentally retarded patients, using fresh, free-hand made lamellar grafts. The mean follow-up period was 31.5 months. The grafts remained clear and well adapted in 7 cases (63.6%). Necrosis of the lower part of the graft occurred in 3 eyes (27.3%), and was probably caused by persisting epithelial defects. Only one of these grafts had to be removed. Despite concurrent eye diseases, such as cataract and possible amblyopia, an improved overall visual function was reported in 5 of the 11 patients (45.5%). No vision-threatening complications related to the epikeratophakia surgery was found.

Four different methods for transferring conjunctival fluid to stix test pads were studied. One hundred and twenty eyes from 120 cataract-extracted patients (35 in the operated eye 0-5 days post-operatively and 85 in the contralateral eye) were included in the study. Transfer of fluid by a glass rod from the lateral part of the inferior fornix was demonstrated to be the most suitable method, showing the highest sensitivity to leucocyte-esterase (83%, N = 120, p < 0.05) and with a specificity equal to that of the other methods tested (cotton, spongostan, Schirmer paper strip). The glass rod method is suitable for detecting blood, nitrite, albumin, pH, and glucose, and is a both quick and unintrusive procedure. All four transferring methods may, however, cause an increased desquamation of epithelial cells and an increased amount of mucus.

The ultrastructure of the lens capsule remnants in an eye with known fibrillopathy (pseudoexfoliation/exfoliation syndrome) subjected to an extracapsular cataract extraction (ECCE) and lens implantation 11 months earlier was examined. Lens epithelial changes typical in lenses with fibrillopathy were observed. The well-known fibrils radiated from pits in the lens epithelial cells, forming a deep layer in the lens capsule and the Busacca bushes on the capsule surface. It thus appears that the production of fibrillar material from lens epithelium may continue after ECCE and implantation of an intraocular lens. A possible connection between intracellular and extracellular fibrils was noticed.

Samples of the vitreous were analysed in order to identify changes of soluble proteins in vitreo-retinal disease. The soluble proteins of the vitreous were separated on an anion exchange column (Mono-Q). The degree of neutral proteolytic activity in vitreous body was also measured. The vitreous from cataract cases without vitreoretinal disease was characterized by its low content of soluble proteins equivalent to about 1% of that of serum. Albumin and transferrin were the major identified components and their concentrations were approximately 0.85 and 0.03 g/l, respectively. In cases with vitreoretinal disease the vitreous showed changes of total soluble protein and the appearance of additional protein peaks. In patients with PVR the albumin concentration in the vitreous was found to be three times higher as compared to the control group consisting of patients with cataract. Neutral proteolytic activity in the vitreous was relatively low in both normal and pathological vitreous.

A case of Enterococcal endophthalmitis developed following an extracapsular cataract extraction. The infection was successfully treated with intravenous and intravitreal ampicillin, but a secondary glaucoma led to a later enucleation. We report a case of postoperative endophthalmitis with an unusual etiology, which did not respond to common treatment.

Vitrectomy was performed in 10 patients in combination with posterior chamber intraocular lens (IOL) insertion. Indications for vitrectomy included traumatically dislocated cataract, choroidal hemorrhage, epiretinal membrane, lens involving intraocular foreign body, vitreous hemorrhage, and extruded anterior chamber IOL. Postoperative visual acuity improved in each case. The main advantages of simultaneous IOL insertion, in selected cases, are reduced cost and inconvenience, and more rapid visual rehabilitation.

Two sisters are described with a disorder characterised by mental retardation, congenital cataract, progressive spinocerebellar ataxia, sensorineural deafness, and signs of peripheral neuropathy. Progressive hearing loss, ataxia, and polyneuropathy became evident in the third decade. The differential diagnosis of this syndrome is discussed including the syndromes described by Berman et al and Koletzko et al.

In the last decade it has become quite clear that oxygen free radicals are involved in a vast amount of diseases such as cataract, atherosclerosis, rheumatism, arthritis, Parkinson's disease, reperfusion injuries and many others. The induction of defence systems against certain stresses (heat shock, inflammation) is also mediated by activated oxygen species. Oxygen-activation and -desactivation has to be regulated and well attenuated in aerobic cells and tissues. The biochemical basis of the biological efficacy of oxidants is thus based on a sophisticated balance between catalysis of production and reactivity of oxygen radicals by certain cofactors and transition metals on the one hand and on a reliable detoxification by antioxidants or metabolic chains on the other hand. In this communication, different oxygen activating principles are compared and the biochemical basis for the induction of repair processes by a synthetic heme oxidant, (Tetrachlorodecaoxide, TCDO) is presented.

A case of posterior lens capsular abscess occurring many months after an extracapsular cataract extraction is presented. This was caused by a mixed infection involving Propionibacterium acnes and Staphylococcus epidermidis. The significance of Staph epidermidis after such a long postoperative period is uncertain, but the case shows features typical of secondary endophthalmitis due to P acnes, including a long delay in onset and a grumbling course not brought under control by medical treatment. It supports the theory that the nidus of infection is localised in the posterior lens capsule by showing development of a visible capsular abscess with associated vitreous involvement. The subsequent removal of the capsule and vitreous, despite leaving the intraocular lens in place, led to complete resolution of the inflammation. Both organisms have previously been found to be sequestered in the posterior lens capsule by histological and microbiological examination of excised capsular specimens. It is important to consider them as possible causative agents in the formation of a postoperative capsular abscess.

The increasing demand for cataract surgery, combined with limited resources, has created renewed interest in daycase admission. We have audited the results of all daycase and inpatient cataract surgery in a large unit over a six-month period to determine the factors influencing daycase admission and surgical outcome; 34% of cataract patients were admitted as daycases in the study period. Neither distance travelled by the patient nor age appear to influence daycase admission. However, the differing policies of the individual consultant surgeons resulted in a wide variation in the number of operations performed on a daycase basis by each firm. The rate of preoperative complications was unaffected by daycase admission, by the grade of surgeon operating, or by the type of anaesthetic employed. Only 2.1% of daycase admissions resulted in unplanned inpatient admission on the day of surgery, with another 2.1% being readmitted within six months of surgery. Late cancellation of surgery was much lower for daycases (0.4%) than for inpatients (5.1%).
