First record of Luidia atlantidea Madsen, 1950 (Echinodermata: Asteroidea: Paxillosida: Luidiidae) in the Sidi-Medjdoub areaMostaganem (West Algerian coast, Mediterranean Sea).

The genus Luidia is currently represented in the Mediterranean Sea by three species, namely Luidia ciliaris (Philippi, 1837), Luidia sarsii sarsii (Dben Koren in Dben, 1844) and Luidia atlantidea (Madsen, 1950) which is an Atlantic species recently reported from the Spanish and Tunisian coasts. Two individuals of Luidia atlantidea were collected as bycatch from small-scale fisheries in the region of Sidi-Medjdoub (Mostaganem, Algeria) at a depth of 53 m. The detailed study of the morphological and anatomical characters allowed us to formally identify the two individuals of Luidia atlantidea and therefore to report it for the first time in the Algerian West coast.

Long-Term Results of Vitrectomy for Macular Holes after Failure of Vitreolysis.

Purpose: Ocriplasmin injection may close some small-to-medium macular holes associated with vitreoretinal traction. If the treatment fails, does vitrectomy and gas injection yield the same results as primary surgery?

Material And Methods: We report a retrospective case series study of 3 eyes of 3 consecutive patients operated on a few months after initial intravitreal injection of ocriplasmin and enlargement of the macular hole. The minimal follow-up period after surgery was 18 months.

[Study of the results scleral-fixated intraocular lenses in the absence of capsular support].

Introduction: In the absence of sufficient capsular support, scleral fixation of the intraocular lens is an interesting alternative. The goal is to evaluate this implantation technique when traditional implantation is impossible.

Patients And Methods: This is an observational, retrospective, monocentric study at the Amiens university medical center between August 2013 and March 2016.
