Retained soft contact lens masquerading as a chalazion: a case report.

A misplaced contact lens is a common ocular emergency presenting to the eye casualty. We report a case of lost soft contact lens which migrated in the lid and presented 13 years later with symptomatic eye lid swelling. Authors in the past have reported migration and subsequent retention of lost hard lenses in locations such as the superior fornix and eyelid. To the best of our knowledge, misplaced soft contact lens masquerading as a chalazion has not been reported in the literature. Consideration should be given to the possibility of a retained contact lens in a patient with a history of a lost or misplaced lens, and examination of the ocular surface with double eversion of the upper lid should be performed.

The Pulfrich phenomenon; clumsiness and collisions which can be ameliorated.

The Pulfrich phenomenon has been described many times but usually just as an interesting academic issue with only diagnostic significance. The phenomenon is due to the fact that patients with unilateral optic neuropathy due to ischaemia, facial injury or multiple sclerosis may have delayed transmission of retinal responses to light from one eye to the brain. This leads to an altered and incorrect interpretation of the pathway and direction of moving targets. Clinicians should be aware of the unique symptomatology of the Pulfrich phenomenon because it is often difficult for patients to describe their symptoms which can be both unpleasant and troublesome. An appropriate tint in either a spectacle or contact lens over the normal eye delays retinal conduction, so re-establishing visual processing symmetry and ameliorating the symptoms.

Spontaneous intraocular lens extrusion in a patient with scleromalacia secondary to herpes zoster ophthalmicus.

We report a case of spontaneous intraocular lens (IOL) extrusion in association with scleromalacia 10 years after uneventful endocapsular surgery. The patient had a history of iridocyclitis secondary to herpes zoster ophthalmicus in the affected eye. A minimally invasive approach involving repositioning the IOL and closure with a conjunctival flap resulted in restoration of visual acuity.

The relationship between stress and acute anterior uveitis.

PURPOSE: To examine the relationship between stress and anterior uveitis using the General Health Questionnaire (GHQ) and the Social Readjustment Rating Questionnaire (SRRQ). METHODS: Patients attending eye casualty with acute anterior uveitis (AAU) and suitable controls were asked to complete the GHQ and the SRRQ. A follow-up postal survey, using the same questionnaires, was repeated at least 3 months later amongst AAU patients only. Scores for the GHQ and SRRQ at initial presentation and at follow-up were compared for different groups. RESULTS: Over 12 months, 42 patients and 25 controls participated in the first stage of this study. Patients with AAU had higher GHQ scores than controls (mean 6.8 versus 3.2, p = 0.01). A total of 25 patients responded to the follow-up postal survey. At follow-up, 13 had experienced resolution and 12 had recurrence. In the group with resolution, there was a significant fall in GHQ scores (mean 6.1 versus 1.5, p = 0.0044). Patients with recurrence had higher GHQ scores than those with resolution (mean 6.8 versus 1.5, p = 0.02). CONCLUSIONS: Using the GHQ reveals a clear relationship between stress and the recurrence of AAU in susceptible individuals.
