Photo Essay Multimodal imaging of multiple macular holes Aditya Verma, Preet Kanwar Sodhi Key words: Fundus autofluorescence, multiple macular holes, multimodal imaging, optical coherence tomography

A 42‑year‑old male presented with decreased vision in the left eye since 4 years. His best‑corrected visual acuity was 6/6, N6 in the right eye (OD) and 6/36, N36 in the left eye (OS). The anterior segment examination was unremarkable. The fundus was normal for OD, whereas OS revealed three retinal holes over the macula  [Fig.  1a and 2a]. The optical coherence tomography (OCT) revealed a normal foveal contour for OD, whereas OS showed two full‑thickness holes over macula (H1 and H2) and a lamellar hole  (H3) inferiorly  [Figs.  1b, 2b and c, respectively]. H1 and H2 showed central hypoautofluorescence, with a rim of hyperautofluorescence surrounding each hole, an intervening hypoautofluorescence, and an additional outer surrounding rim of dumb‑bell‑shaped hyperautofluorescence  [Fig.  3b]. The OD showed a normal fundus autofluorescence [Fig. 3a]. The multifocal electroretinogram  (mfERG) showed mildly reduced foveal peak in OD, whereas OS showed reduced responses corresponding to the location of holes [Fig. 4a and b, respectively].

Discussion Multiple macular holes, albeit rare, have been reported in the past.[1‑3] Multimodal imaging helps understanding the pathophysiology and prognosis. The OCT in this case showed the presence of disorganized retinal architecture in the bridging retinal tissue. The central hypoautofluorescence of H1 and H2 was in contrast to what has been observed in the literature and may suggest chronicity. The surrounding hyperautofluorescence is consistent with the outer retinal layer atrophy. H3 showed a uniform hypoautofluorescence, corresponding to the outer retinal atrophy. The mfERG showed reduced responses and depressions corresponding to all the holes. The mild peak in the center confirmed the presence of eccentric fixation of the left eye, located at the intervening retinal tissue between H1 and H2. The etiology was found to be idiopathic and the patient was advised observation. Declaration of patient consent The authors certify that they have obtained all appropriate patient consent forms.

Figure 3: Fundus autofluorescence (FAF) images of the right (a) and the left (b) eye. The FAF of the right eye was normal, whereas the FAF in the left eye was typical. The full‑thickness holes showed a central hypoautofluorescence, with a rim of hyperautofluorescence surrounding each hole, an intervening hypoautofluorescence, and an additional outer surrounding rim of dumb‑bell‑shaped hyperautofluorescence. The partial thickness hole showed a uniform hypoautofluorescence

Multicolor imaging features of dissociated optic nerve fiber layer after internal limiting membrane peeling

Dissociated optic nerve fiber layer (DONFL) is an after effect of internal limiting membrane (ILM) peeling for macular hole repair.[1] It is thought as a result of damage of Muller cell processes, exposing the retinal nerve fiber layers.[2] Multicolor (MC) imaging available on spectralis spectral domain optical coherence tomography (SDOCT) platform uses three laser lights to provide topographic image of the retina.[3] We herein report the MC imaging characteristics of DONFL.

A  15‑year‑old boy  underwent full‑thickness macular hole repair for traumatic macular hole following blunt trauma with cricket ball. Vitrectomy with ILM peeling and C3F8 gas tamponade was performed following which the best‑corrected visual acuity improved from 20/60 to 20/30 at 1‑month follow‑up. The SDOCT of right eye revealed closing macular hole along with irregular depressions in retinal contour due to thinning of ganglion cell layer
