Spontaneous eyelid expansion after full thickness eyelid resection and direct closure.

BACKGROUND/AIMS: Direct closure of eyelid defects gives excellent functional results but is usually restricted to defects measuring less than a quarter of the eyelid length for fear of distorting the palpebral aperture and compromising lid function. The authors have used direct closure in larger defects. The aim of this study was to establish the effects of direct closure of full thickness eyelid margin defects under tension on the palpebral aperture dimensions. METHODS: A consecutive series of patients who had undergone one eyelid, full thickness lid resection repaired by direct closure were identified and invited to have both eyes photographed. The palpebral apertures of both eyes were measured from the photographs by a masked observer. The amount of eyelid resected was recorded from the operation notes. The unoperated palpebral aperture was used as the control. The result were analysed using a paired samples t test. RESULTS: The photographs of 18 patients were included in the analysis. The mean width of excised full thickness lid tissue was 15 mm (range 7-26 mm). The mean vertical palpebral aperture height was 9.2 (SD 1.4) mm in the operated eye as opposed to 9.3 (SD 1.2) mm in the non-operated eye. The mean horizontal palpebral aperture width was 26.1 (SD 1.9) mm in the operated eye as opposed to 26.4 (SD 1.8) mm in the non-operated eye. There was no statistically significant difference between the operated and unoperated horizontal and vertical palpebral measurements. CONCLUSIONS: Direct closure of large full thickness eyelid defects is possible in selected patients with excellent functional and cosmetic results. Eyelid tissue expansion occurs spontaneously following direct eyelid defect closure under tension, restoring the palpebral aperture dimensions.

Do patients with age related maculopathy and cataract benefit from cataract surgery?

AIMS: To assess the benefits of cataract extraction in patients with age related maculopathy (ARM). METHODS: 1073 randomly selected cataract operations were reviewed and 99 cases of preoperatively recognised ARM were identified for investigation. Data relating to visual function were retrieved from case notes, and patient responses to a questionnaire were analysed. RESULTS: 98% had dry or unspecified ARM. Only 2% had exudative maculopathy. 81% of cases had an improvement in best distance acuity; mean change 0.44 logMAR (change of 6/36 to 6/12). 65% responded to the questionnaire; 67% felt that the operation had been worthwhile, 17% had mixed feelings, and 17% thought it not worthwhile. CONCLUSIONS: This study, which is the first of its kind to be reported, shows a clear benefit from cataract surgery in the majority of patients with ARM. However, the prevalence of ARM in this study is lower than expected, suggesting that some patients with both ARM and cataract were not listed for surgery. The design of a prospective study to quantify the subjective and objective benefits of cataract surgery in these patients is outlined and predictors of successful outcome identified. This will promote the development of guidelines for the surgical management of this group of patients.

Intraocular pressure control and fluctuation: the effect of treatment with selective laser trabeculoplasty.

AIMS: To evaluate the effect of selective laser trabeculoplasty (SLT) on intraocular pressure (IOP) control and diurnal tension curves of patients with open-angle glaucoma (OAG) and ocular hypertension (OHT), and to compare this effect with that of latanoprost. METHODS: Forty patients were randomised to receive either SLT or latanoprost. IOP control was evaluated by comparing pretreatment values with post-treatment measurements on day 3, week 1, month 1 and 4-6 months; success was defined as 20% decrease in IOP. Tension curves were plotted prior to treatment and 4-6 months afterwards; success was 50% reduction in fluctuation. RESULTS: SLT decreased pressure by 4.7 mm Hg on average (95% CI 3.6 to 5.7 mm Hg; p<0.01). The reduction was similar for latanoprost at all follow-ups except month 1; 75% of SLT patients and 73% of latanoprost patients achieved success in IOP control (p = 0.4). SLT significantly reduced IOP fluctuation, but latanoprost was more effective (3.6 mm Hg, 95% CI 3.2 to 3.9 mm Hg vs 2.5 mm Hg, 95% CI 2.2 to 2.9 mm Hg for SLT; p = 0.04). Success in fluctuation reduction was 50% for SLT and 83% for latanoprost (p = 0.045). CONCLUSIONS: Both SLT and latanoprost had a significant impact on IOP control and fluctuation. While latanoprost may be more likely to reduce IOP fluctuation, SLT has the benefit of being a one-time intervention not requiring ongoing patient compliance.

Primary antiphospholipid syndrome unusual presentation in a seventy two year old man.

A 72 year old man with a history of TIAs and stroke with unexplained moderately raised ESR presented a year later with rapid deterioration of vision in his left eye because of central retinal vein occlusion. Primary antiphospholipid syndrome is found in patients with history of arterial or venous thromboembolism, thrombocytopenia and recurrent fetal loss without features of SLE.
