Tele-ophthalmology for the treatment in primary care of disorders in the anterior part of the eye.

Desktop videoconferencing at 384 kbit/s was used for a trial of tele-ophthalmology consultations between a general practitioner (GP) and an experienced ophthalmologist. Forty-two consecutive patients from St Erik's Eye Hospital emergency ward with disorders in the anterior part of the eye were examined. There was an excellent correlation between the diagnoses made with telemedicine support and those made by the ophthalmologist directly. Subsequently, the GP made 121 eye examinations in two years out of a total of approximately 300-400 examinations at the health-care centre. In the first year the GP examined and treated 45-50% of the cases on his own and 30-50% with telemedicine support. In the second year he treated 55-80% of the cases on his own and 5-35% with telemedicine support. Tele-ophthalmology in primary care appears to be reliable and is likely to be valuable in rural areas, where the distance to an ophthalmologist can be a significant obstacle to satisfactory diagnosis and treatment.

Blindness in glaucoma patients.

In order to determine the risk for bilateral blindness from glaucoma and to which extent other diseases are responsible for the disability, the registers of low vision clinics were surveyed. All registered patients still alive in 1991 with the diagnosis of glaucoma were included. Eighteen hundred and ninety-five patients fulfilled these criteria. Blindness was defined as bilateral visual acuity < or = 0.1. The majority of the patients (68%) had a visual acuity better than 0.1. The remaining 590 patients had a visual acuity < or = 0.1. In this latter group glaucoma was the reason for the low visual acuity in 20%, glaucoma in combination with other eye diseases in 35% and other eye diseases in 44%. Macular degeneration and cataracts were the main causes of the low vision in the latter group. The prevalence of glaucoma blindness in the Stockholm region was found to be 0.007% for glaucoma and 0.020% for glaucoma in combination with other eye diseases.

Perforating eye injury in the Stockholm population. An epidemiological study.

We studied the occurrence of perforating eye injury (PEI) during the period 1974-1979 in the population (1.5 million) of Stockholm county. Information was obtained from medical and population registries, medical records and personal interviews. PEI was almost 6 times more common in men than in women, and age specific incidence rates varied from 94.3 per million person years in young men (10-19 years) to 3.9 in elderly women (60-69 years). The risk appeared somewhat increased in the unmarried, but not in foreign citizens. Most injuries occurred during the day with no less than 54% between 10 a.m. and 4 p.m., and only 2% after 9 p.m. The most common activity at the time of injury was paid work (27%) followed by play or sport (23%), while 10% of the cases were due to fight or assault. Among those injuried in paid work, the most common occupation was construction worker or building metal worker. Metal and glass fragments were the most common perforating objects, but thorns from planted bushes caused many perforating injuries in children.

Ultrasonic measurements of the eye in the newborn infant.

The right eyes of 28 newborn infants have been examined retinoscopically, and the anterior chamber depth, the lens thickness and the length of the virteous were measured by ultrasound. In 15 of the infants keratometry was performed using the Javal-Schiötz keratometer. The total axial length of the eye was found to be longer the heavier the weight of the baby, whereas the lens thickness showed no correlation to the total axial length or to the weight of the baby. In only 1/3 of the babies was the corneal astigmatism less than 0.5 D. A significant correlation (P less than 0.01) was found between the total axial length of the eye and the length of the corneal radius.

Ocular complications in recipients of kidney transplants.

104 renal transplant recipients have been examined regarding ocular complications. A high incidence of posterior subcapsular cataracts has been found, increasing with time after operation. Only 2 cases of open angle glaucoma were found, indicating a seemingly small risk for developing a corticosteroid-induced glaucoma in such patients. A high frequency of treatment-resistant herpes simplex keratitis, probably due to reduced corneal resistance, was found.

Some characteristics of steroid diabetes: a study in renal-transplant recipients receiving high-dose corticosteroid therapy.

Risk factors and course of steroid diabetes were investigated in 145 renal-transplant recipients who were given a high-dose steroid regimen. Persistent steroid diabetes developed in 25% of the patients and transient diabetes in another 22%. When antidiabetic therapy was required, insulin had to be given in 50%. The incidence of steroid diabetes correlated with steroid dose, age, body weight, and diabetes heredity but not with abnormal glucose tolerance or with another complication of steroid therapy, posterior-pole lenticular cataract. There was no association with HLA-A and B antigens. Thus, steroid diabetes is a frequent complication of high-dose corticosteroid therapy and is similar to type II diabetes. However, it often requires insulin therapy.
