Background

Full-thickness macular holes (FTMHs) are foveal neurosensory defects that affect all layers of the neurosensory retina and tend to increase in size with time.

FTMHs are evaluated by optical coherence tomography (OCT). The International Vitreomacular Traction Study Group classifies macular holes according to their size (small, medium, or large) and their vitreous status as determined by OCT, differentiating between the presence or absence of vitreomacular traction (VMT) [1]. FTMHs can be further subdivided according to their etiology into primary and secondary forms. Primary FTMHs are the result of vitreous traction. Secondary FTMHs differ in etiopathogenesis since VMT is not the primary reason for the macular hole development. These secondary macular holes are seen, for instance, in high myopia (myopic macular hole), in macular telangiectasia (MacTel), in cystoid macular edema caused by several retinal diseases such as retinal vein occlusion, diabetic retinopathy, and posterior uveitis, in proliferative diabetic retinopathy, and in solar maculopathy.

The current treatment for FTMHs is combined pars plana vitrectomy (PPV) and internal limiting membrane (ILM) peeling with consecutive gas or air tamponade. Cases of spontaneous closure of predominantly smaller FTMHs have been described in the literature [2]. The reported spontaneous closure rate for small FTMHs (< 250 µm, measured by OCT) without VMT is between 4 and 11.5% [3].

Emerging evidence suggests that topical treatment with carbonic anhydrase inhibitors (CAIs), steroids, and/or nonsteroidal anti-inflammatory (NSAID) drugs can lead to closure of small FTMHs without surgical intervention [4]. As FTMHs can close spontaneously, especially smaller macular holes, the best time point for a PPV or ILM peeling remains unclear. Furthermore, the benefit of delaying a surgical intervention and treating the patient with topical eye drops to increase the chance of closure remains to be elucidated [5].

We report our first two consecutive cases of FTMH closure under topical treatment at the University Hospital Basel, Switzerland.
