Etiologies, Characteristics, and Management of Pediatric Macular Hole

Full-Thickness Macular Hole in a Pediatric Patient With Normal Vision

A 17-year-old boy presented with a full-thickness macular hole, with 20/20 vision with eccentric fixation in the left eye. Examination of the left eye showed a large macular hole with a base diameter measuring 1,680 μm and temporal macular and mid-peripheral retinal atrophy on ultra-high-definition optical coherence tomography (OCT) scans. Microperimetry showed eccentric fixation with good nasal sensitivity. A 12x12-mm extended-field swept-source OCT angiogram showed flow loss in the temporal macula, with slight reduction noted in the choriocapillaris. Given excellent visual acuity, good tolerance by the patient, and large atrophic hole, the decision was made for observation rather than surgery.

AN EIGHT-YEAR RETROSPECTIVE STUDY OF THE ETIOLOGIES, CLINICAL CHARACTERISTICS, AND VISUAL OUTCOMES OF PEDIATRIC LAMELLAR MACULAR HOLE

PURPOSE

To explore the etiologies, characteristics, and prognosis of lamellar macular hole (LMH) in pediatric patients.

METHODS

A consecutive series of 59 patients (62 eyes) aged <16 years with MHs (lamellar and full-thickness) treated from 2013 to 2021 in a tertiary center was reviewed. Data collected included demographic and clinical characteristics, management, and outcomes of patients presenting with LMH.

RESULTS

Twelve eyes (19.4%) of 11 children had LMH. Seven patients were male, with an average age of 6.9 years. The primary pathologies included X-linked retinoschisis in six eyes (50%); familial exudative vitreoretinopathy in two (16.7%); and ocular toxocariasis, Coats disease, persistent hyperplastic primary vitreous, and idiopathic LMH with associated lenticonus in one eye (8.3%) each. Four eyes (36.4%) showed tractional appearance and seven (63.6%) degenerative. All degenerative LMH showed ellipsoidal zone defect, significantly higher than that in the tractional group (25%, 1/4) ( P = 0.024). Five eyes achieved closed LMH and limited visual gain, four underwent surgery, and one closed spontaneously.

CONCLUSION

X-linked retinoschisis was the most frequent primary cause in pediatric LMH. Two types of LMH can be classified: tractional and degenerative. The latter showed a higher rate of ellipsoidal zone defect. Vision improved after LMH closed, regardless of surgery or spontaneous closure.

Clinical characteristics of full thickness macular holes that closed without surgery

PURPOSE

To ascertain the anatomic factors that help achieve non-surgical sealing in full thickness macular hole (FTMH).

METHODS

Retrospective collaborative study of FTMH that closed without surgical intervention.

RESULTS

A total of 78 patients (mean age 57.9 years) included 18 patients with blunt ocular trauma, 18 patients that received topical or intravitreal therapies and 42 patients with idiopathic FTMH. Mean±SD of the initial corrected visual acuity (VA) in logMAR improved from 0.65±0.54 to 0.34±0.45 (p<0.001) at a mean follow-up of 33.8±37.1 months. FTMH reopened in seven eyes (9.0%) after a mean of 8.6 months. Vitreomacular traction was noted in 12 eyes (15.8%), perifoveal posterior vitreous detachment in 42 (53.8%), foveal epiretinal membrane in 10 (12.8%), cystoid macular oedema (CME) in 49 (62.8%) and subretinal fluid (SRF) in 20 (25.6%). By multivariate analysis, initial VA correlated to the height (p<0.001) and narrowest diameter of the hole (p<0.001) while final VA correlated to the basal diameter (p<0.001). Time for closure of FTMH (median 2.8 months) correlated to the narrowest diameter (p<0.001) and the presence of SRF (p=0.001). Mean time for closure (in months) was 1.6 for eyes with trauma, 4.3 for eyes without trauma but with therapy for CME, 4.4 for eyes without trauma and without therapy in less than 200 µm in size and 24.7 for more than 200 µm.

CONCLUSION

Our data suggest an observation period in new onset FTMH for non-surgical closure, in the setting of trauma, treatment of CME and size <200 µm.

Optical coherence tomography imaging of the pediatric retina

Optical coherence tomography is an increasingly important part of the retinal specialist's and general ophthalmologist's toolkit for diagnosing and managing retinal disease. This review summarizes the unique considerations and available imaging systems with which pediatric ophthalmologists should be familiar when attempting optical coherence tomography in children. Normal developmental changes in foveal and extrafoveal structure and the need for an established pediatric normative database of retinal thicknesses are reviewed. Finally, applications of optical coherence tomography imaging to selected representative pediatric retinal diseases are introduced as examples of how optical coherence tomography in children is furthering the diagnosis and management of vision-threatening retinal diseases.
