A variety of nonstaining patterns around macular holes can be observed using BBG, and these patterns correlate to the amount of cellular tissue on the vitreous side of the ILM seen histologically. These patterns could be used to guide the ILM peeling requirement or extent in future studies.

Aims: Analysis of pre-operative spectral domain optical coherence tomography (SD-OCT) characteristics of full-thickness macular holes (FTMH) and effect on optimum management. Methods: We retrospectively reviewed SD-OCT characteristics of a consecutive cohort of patients waitlisted for FTMH surgery and categorized them by current evidence-based treatments. Results: Out of the 106 holes analysed, 36 were small, 40 medium and 30 large. Initially, 33 holes had vitreomacular adhesion (VMA). 41 holes were analysed for change in characteristics with a median duration of 8 weeks between the scans. The number of small or medium holes decreased from 20 to 6 and that of large holes doubled. The number of holes with VMA halved. Smaller hole size (p = 0.014) and being phakic (p = 0.048) were associated with a larger increase in size. The strongest predictor of hole progression into a different surgical management category was the presence of VMA. Conclusion: FTMH characteristics can change significantly pre-operatively and affect optimal treatment choice.

The extent of DONFL observed postoperatively can be partly explained by the amount of retinal side cellular debris on the retinal side of the peeled ILM. Surgical strategies which minimize this material could reduce the extent of DONFL.

ILM peeling technique and possibly other surgeon-specific factors appear to influence the extent of DONFL observed after ILM peeling macular hole surgery.

IntroductionFluocinolone acetonide (FAc) intravitreal implant (ILUVIEN®; Alimera Sciences Limited, Aldershot, UK) has been approved in the UK for the treatment of chronic diabetic macula edema, insufficiently responsive to available therapies. It is inserted into the vitreous cavity through a 25-gauge needle. Migration of the implant to the anterior chamber (AC) can occur through gaps in the posterior capsule especially in vitrectomized eyes. Early removal of AC-dislocated FAc implant is essential to prevent corneal edema and damage from raised intraocular pressure.AimTo demonstrate a simple and novel technique, with a previous capsular tear, for removal of AC-migrated FAc implant and reinsertion into the vitreous cavity without compromising implant integrity.MethodA side port incision was created with a keratome and an anterior chamber maintainer introduced and secured. Subsequently, a corneal incision was created at 12 o’clock through which a 23-gauge backflush needle (flute needle) was advanced into the anterior chamber and passive suction used to secure the implant. The flute needle was then placed through the defect in the posterior capsule and the exit port blocked, causing loss of suction and allowing the implant to fall into the posterior segment. The sulcus intraocular lens (IOL) was centralized simply by manipulating it approximately 180 degrees to provide adequate anterior capsule support.ResultsThe FAc implant was successfully removed from AC in two patients and reinserted into the vitreous cavity without damage or complications either for the eye or the implant. IOL in both patients were repositioned to close the gap in posterior capsule. After 2 months, the implant remains in the vitreous cavity. This paper presents data from one of these cases.ConclusionUsing 23-gauge flute needle to retrieve dislocated FAc implant is a safe and easy technique.FundingAlimera Sciences Ltd.Electronic supplementary materialThe online version of this article (doi:10.1007/s40123-015-0035-1) contains supplementary material, which is available to authorized users.
