Impact of AREDS in a developing country 5 years after publication of the study.

PURPOSE: The Age-Related Eye Disease Study (AREDS) is the only large-scale study to demonstrate a reduction in the risk of progression to end-stage age-related macular degeneration (AMD) when vitamin supplementation was given to patients with advanced forms of the disease. Our study assesses the impact of this study on vitamin supplementation in patients with advanced AMD from 5 years before publication of the AREDS results until 5 years after. METHODS: Medical records of patients with AMD presenting between September 1996 and October 2006 were reviewed. Patients were subclassified according to AREDS categories. The proportion of advanced cases on vitamin replacement before October 2001 was compared to that after October 2001. Since October 2001, the different reasons for abstinence were investigated and analyzed. RESULTS: Only 2403 patients of the 40,000 medical records reviewed met the AREDS AMD criteria. Of these, 137 patients verifying categories 3 and 4 were diagnosed prior to October 2001. Fourteen were on supplements then. Fifty-three patients complied with the represcribed vitamins during subsequent visits after October 2001, raising the percentage significantly to 48.9% (p<0.001). Also, from October 2001 until October 2006, an additional 76 patients verified categories 3 and 4. Fifty-three (69.7%) of them were on vitamins (p=0.001). Financial burden was the principal reason for abstinence in 67.7% of patients prescribed vitamins after October 2001. CONCLUSIONS: The results of AREDS had an impressive impact on prescribing supplements in AREDS category 3 and 4 patients in Lebanon. The main reason for noncompliance is financial.

Mild myopic astigmatism corrected by accidental flap complication: a case report.

A 35-year-old female presented for laser in-situ keratomileusis (LASIK). Her preoperative eye exam was normal, with a preop refraction of OD -2.50 D Sph +1.25 D Cyl x175 and OS -2.75 D Sph +1.50 D Cyl x165 (cycloplegic and manifest), with 20/20 BCVA OU. The central pachymetry reading was 553 mum in the right eye. Preoperative topography was normal. At the start of the pendular microkeratome path, some resistance was felt, but the microkeratome continued along its path. Upon inspection of the flap, there was a central rectangle of intact epithelium with two mirror-image flaps on both sides. The flap was repositioned and LASIK was discontinued. The cornea healed with two faint thin linear vertical parallel scars at the edge of the pupil. Postoperative inspection of the blade revealed central blunting. One month postoperatively, the uncorrected visual acuity (UCVA) was 20/20. Manifest and cycloplegic refractions were plano. This is an interesting case of accidental flap complication resulting in the correction of mild myopic astigmatism.
