Outcomes of epiretinal membrane surgery in highly myopic eyes: a case-control study.

AIMS: To evaluate the outcomes of epiretinal membrane (ERM) surgery in highly myopic eyes and to compare them with those from non-highly myopic eyes. METHODS: Retrospective nested case-control study from a cohort of 1776 consecutive patients (1776 eyes) who underwent surgery for ERM. Fifty-seven highly myopic eyes (with axial length longer than 26 mm) were included in the study group and were matched for preoperative visual acuity and duration of symptoms with 57 non-highly myopic control eyes selected from the same cohort. The best-corrected visual acuity (BCVA), the relationship between axial length and visual improvement, the central macular thickness (CMT) and the surgical complications were analysed. RESULTS: The mean axial length was 27.3±1.1 mm in highly myopic eyes and 23.1±1 mm in controls (p<0.001). At the 1-year final examination, the mean BCVA significantly improved from 0.62±0.23 logarithm of minimal angle of resolution (logMAR) to 0.27±0.21 logMAR in the study group (p<0.001) and from 0.61±0.22 logMAR to 0.25±0.15 logMAR in the control group (p<0.001). Similarly, the mean CMT significantly decreased in both groups (p<0.001). The two groups did not differ statistically in terms of visual and anatomical changes as well as surgical complications. There was no significant correlation between axial length and visual recovery. CONCLUSIONS: ERM surgery resulted in similar anatomical and functional outcomes in both groups. Longer axial length does not seem to affect visual improvement and the complication rate.

Ocular symptoms are not predictive of ophthalmologic inflammation in inflammatory bowel disease.

BACKGROUND: Ocular manifestations are frequent in patients with inflammatory bowel disease. AIM: To evaluate for the first time the value of ocular symptoms in predicting ophthalmologic inflammation in inflammatory bowel disease. METHODS: All consecutive inflammatory bowel disease patients seen in the Department of Gastroenterology (Nancy, University Hospital, France) between April 2009 and July 2011 were interviewed for this cross-sectional study using a pre-established questionnaire. If the patient had at least one ocular symptom, he systematically underwent an ophthalmologic examination (visual acuity, Break-Up Time test, Schirmer Test, slit-lamp exam with fundus examination). RESULTS: This cross-sectional survey was completed by 305 patients: 169 were women (55.2%), 228 had Crohn's disease (74.5%). Ninety-eight patients (32%) reported at least one ocular symptom: ocular irritation (56.8%), red eye (40.5%), blurred vision (37.8%), progressive visual loss (34.4%), ocular pain (31.1%), myodesopsia (23.3%), eyelid secretion (12.2%), dry eye (9.5%), watering (6.8%), diplopia (5.4%), metamorphopsia (4%), and sudden visual loss (4%). Following ophthalmologic examination (n=74), 41.9% patients had evidence of dry eye (n=31), 14.9% blepharitis (n=11) and 1.4% scleritis (n=1). No uveitis was reported. CONCLUSION: Ocular symptoms are frequent in inflammatory bowel disease, but are non-specific and rarely associated with ocular inflammation. Systematic ocular symptoms assessment is of poor value for diagnosing ocular inflammation in inflammatory bowel disease.
