Two cases of diabetic macular edema complicated by an atypical macular hole

Secondary Full-thickness Macular Holes after Diabetic Vitrectomy: Clinical Manifestations and Rational Approaches to the Treatment

Purpose. The aim of the study is to present the clinical characteristics and surgical treatment of secondary full-thickness macular hole (MH) after diabetic vitrectomy (DV) in patients with proliferative diabetic retinopathy (PDR). Methods. In this retrospective, observational, and longitudinal study, we enrolled consecutive patients with PDR who developed MH after DV. The macular structure was evaluated using optical coherence tomography. The clinical characteristics, surgical techniques, and outcomes were also recorded. Results. Three patients developed MH within 6 weeks, which was associated with foveal thinning, residual fibrovascular proliferation, or anterior proliferative vitreoretinopathy. Six patients developed MH originating from the epiretinal membrane (ERM) with lamellar MH (LMH) after a median interval of 16.5 months. Three of them were complicated with retinal detachment (RD). Various surgical procedures were performed according to the clinical scenarios, including internal limiting membrane (ILM) peeling, inverted ILM flap insertion, temporal inverted ILM flap, lens posterior capsular flap insertion, and neurosensory retinal free flap insertion. All patients achieved MH closure after surgery, and 5 patients exhibited improved visual acuity. Conclusions. MH may develop after successful DV, with a high rate of associated RD. Rapid MH formation was attributed to unreleased tractional force and weakened foveal structure. The development of ERM and LMH also led to MH. Various surgical techniques could be used for MH closure.

Full-Thickness Macular Hole Closure Following a Single Intravitreal Injection of Aflibercept in an Eye With Diabetic Macular Edema

Purpose:

This work aims to discuss the case of a 32-year-old man with diabetic macular edema (DME) who underwent successful treatment of a full-thickness macular hole (FTMH) with a single dose of aflibercept.

Methods:

A case report is presented.

Results:

A 32-year-old man with reduced vision and DME in the right eye was found to have a FTMH. The patient was scheduled for pars plana vitrectomy; however, following a single dose of intravitreal aflibercept, the FTMH closed and the patient avoided surgical intervention.

Conclusions:

FTMH formation in DME is a rare complication that typically requires surgical intervention. We present a case of FTMH closure after a single dose of intravitreal aflibercept, which to our knowledge is the first of its kind. This report highlights the importance of considering conservative treatment initially to avoid surgery.
