Abstract

Purpose: To describe a novel technique of macular hole (MH) repair and compare it to the perfluorocarbon liquid (PFCL)-assisted temporal internal limiting membrane (ILM) flap technique. Methods: Twenty-two eyes of 22 patients with MH were randomized on a 1:1 basis into two groups. Group A cases were treated using the Flip and Fix technique, in which the single-layer ILM flap was flipped, flattened over the macula using PFCL, and fixed in place using two drops of autologous nonheparinized blood over the superonasal and inferonasal edges of the flap (away from the MH center). Group B patients had the classic temporal ILM flap technique without using the PFCL or autologous blood. All patients were followed up for a period of 6 months after the surgery. Results: No significant difference was observed in initial and final visual acuities between Groups A and B. Intraoperative flap displacement did not occur in Group A and occurred in two eyes in Group B (18.2%). One of them showed failed MH closure and required reoperation. These two cases had a final (W shape) MH closure and a worse final vision than the remaining cases, which had either a U shape or V shape final MH closure. Conclusions: The study results show that the Flip and Fix technique is as effective as the PFCL-assisted temporal ILM flap technique and is associated with less ILM flap displacement risk for the repair of macular holes.

Abstract

Purpose The purpose of this research was to estimate the prevalence of DR in Alexandria and the North-West Delta region. Methods All diabetic patients attending the general ophthalmology clinics (Group 1), diabetic internal medicine clinics (Group 2), or reached out in the local communities (Group 3) were eligible to participate. Fundus photographs were graded according to the Scottish DR grading system by three independent UK-certified graders. Adjudication by a consultant was done when needed. Results Out of 11,033 screened patients, 10,811 had a gradable fundus photograph in at least one eye and were included. The numbers of cases in groups 1, 2 and 3 were 3940, 2826, and 4045, respectively. Males represented 38.35% of the cases. Mean age was 55 ± 12.63. For the whole sample, groups 1, 2 and 3, the DR prevalence was 32.49, 46.4%, 29.13%, and 21.29%, respectively. The prevalence of proliferative DR (grade R4) was 6.16%, 11.83%, 5.02%, and 1.45%, respectively, and of referable maculopathy (Grade M2) was 19.95%, 31.42%, 15.92%, and 11.59%, respectively. In univariate analysis, older age, higher random blood glucose, and longer DM duration were associated with a higher risk of both DR and referable diabetic maculopathy. This association was maintained in multivariate analysis for the high random blood glucose level and the longer duration of DM (but not for the older age). Conclusion A significantly higher prevalence of DR, grades R4 and M2 was found in the hospital-recruited patients than in diabetics from the local communities.
