Purpose: To determine the risk factors for age-related macular degeneration (AMD) in Algerians, and compare these data with those on North Africans living in Italy. Methods: All patients over 55 years of age consulting one of the 23 involved Algerian ophthalmologists were invited to participate, and 1,183 patients were included. Data collection was standardized based on the Simplified Théa Risk Assessment Scale (STARS) questionnaire. A similar study was conducted in North Africans living in Italy (n = 1,011). Patients with only soft drusen and/or pigmentary abnormalities were classified as early AMD, and patients with geographic atrophy and/or neovascular AMD were classified as late AMD. Results: In the final multivariate model, risk for early and/or late AMD was significantly increased with older age, family history of AMD, Black ethnicity, atherosclerosis, beer consumption, high fruit consumption, cataract surgery, myopia, and hyperopia. High consumption of green vegetables was associated with lower risk for both early and late AMD. In comparison with North Africans from Italy, Algerians generally had a healthier profile (younger, less obesity, smoking, and cardiovascular diseases, and higher consumption of fruits and vegetables) and a lower risk for AMD. Conclusion: This study documents risk factors for AMD in North-African populations for the first time.
Purpose To report the practice of orthokeratology (OK) in Algeria and to investigate the visual outcomes, safety and subjective responses with this technique in myopes. Methods A retrospective chart review of 48 participants using OK lenses since January 2010 were included in the study. Lenses were selected and fitted according to the manufacturer’s recommendations using their respective software and the number of lenses required for a successful fit was recorded. Visual acuity (VA) in logMAR units and biomicroscopic findings were recorded for each visit. Subjective ratings was determined with analogue rating scale was filled in by the investigator, the participants were divided into Group 1 (> 4.00D) and Group 2 (< 3.75D) myopic groups for analysis. Results First lens fitting success rate of 64.58%. There was also a significant difference between the BCVA at baseline and VA at Day 1 (P < 0.05), and no significant difference at Day 7, Day 30 and the final visit (P = 0.51, P = 0.93, P = 0.62, respectively), for Group 2. There was a significant difference between the BCVA at baseline and VA at Day 1, 7, 30 and the final visit (P < 0.05), for Group 1. the patients of the second group were happier but the results from the survey were not statistically significant (P = 0.10), no serious complication was reported. Conclusion the technique was efficient and safe as we didn’t have any serious complication, with a high success rate for first lens fitting.
SummaryNowadays, we are experiencing scleral lens rebirth through the development of new designs and materials respecting the anterior ocular surface represented by the cornea, the limbus and the anterior bulbar conjunctiva. But what about the posterior ocular surface, represented by the tarsal conjunctiva, the lid margin and meibomian glands? The interaction of the scleral lens with the posterior ocular surface will be assessed clinically in keratoconus patients wearing scleral lens for more than 2 years and compared in a randomized manner with soft lens, hybrid lens and corneal rigid gas permeable lens wearers and with control sample. Lid wiper epitheliopathy grade, tear film break up time, quality of meibum and meibomian gland trophicity will be compared between different groups…
