A novel surgical technique employing donor sclera in strabismus surgery.

We describe a novel surgical technique employing donor sclera as a spacer to solve the problem encountered in complicated cases of restrictive strabismus surgery when no more muscle or tendon is available for surgical extension of the eye muscle to correct the angle of deviation. This is often the case in patients who have previously undergone extensive surgery and in patients with mechanical restrictions, such as thyroid-associated orbitopathy (TAO).

Using the KM visual acuity chart for more reliable evaluation of amblyopia compared to the HVOT method.

Purpose: To evaluate a new letter matching visual acuity (VA) chart (the KM chart) for children aged 5-7 years, designed as a Monoyer-based chart, in order to obtain a better consistency between school and preschool VA recordings.

Methods: Visual acuities were assessed using three methods: the HVOT, KM and Monoyer charts. Comparisons were made between the KM method versus the HVOT and Monoyer methods, respectively.

Orbital mass in a child causing somnolence, nausea and bradycardia.

Purpose: To highlight the need for referral and prompt intervention when signs of increased intraorbital pressure are present.

Clinical Features: A four year old child presented to hospital with orbital swelling of recent onset, nausea and somnolence. Computed tomography and brain scan demonstrated a normal brain with a mass in the left orbit.

Retinopathy of prematurity in the southern part of Sweden.

The incidence of retinopathy of prematurity (ROP) was studied in prematures in the southern part of Sweden during one year. Nine hospitals participated in the prospective study. During the period 23,745 children were born in the region.

Testing for hypermetropia in the school vision screening programme.

The need and accuracy of a hypermetropia test, recommended as a screening test in Swedish schools, was evaluated in a series of 118 8-year-old children not wearing glasses. The distant visual acuity was determined without correction and with plus spheres of two different strengths, +1.5 D and +2.
