Abstract
Objective
To characterize the multimodal retinal findings of myopic macular pits, a feature
of myopic degeneration.
Methods
A case series of patients with myopic macular pits were studied with multimodal imaging
including color fundus photography, fundus autofluorescence (FAF), near infrared reflectance
(NIR), spectral domain optical coherence tomography (OCT), optical coherence tomography
angiography (OCTA), fluorescein angiography (FA) and indocyanine green angiography
(ICG).
Results
Nine eyes of 6 patients with myopic macular pit were examined. Four patients presented
with multiple pits and 3 with bilateral involvement. All pits were localized in a
region of severe macular chorioretinal atrophy associated with myopic posterior staphyloma.
In 3 eyes, the entrance of the posterior ciliary artery through the sclera was noted
at the base of the pit. Schisis overlying the pit or adjacent to the pit was identified
in 3 patients.
Conclusion
Myopic macular pits are an additional rare sign of myopic degeneration, developing
in regions of posterior staphyloma complicated by severe chorioretinal atrophy and
thin sclera.
Résumé
Objectif
Décrire les observations de l'imagerie multimodale de trous maculaires dans la rétine
du myope en tant que caractéristique d'une dégénérescence myope.
Méthodes
On a eu recours à l'imagerie multimodale – photographie couleur du fond d'œil, autofluorescence
du fond d’œil, spectroscopie de réflectance dans le proche infrarouge, tomographie
par cohérence optique (OCT) en domaine spectral, angiographie-tomographie par cohérence
optique (OCTA), angiographie à la fluorescéine et angiographie au vert d'indocyanine
– chez une série de patients présentant des trous maculaires du myope.
Résultats
Ont ainsi été examinés 9 yeux de 6 patients qui présentaient des trous maculaires
du myope : 4 patients avaient de multiples trous, et 3, une atteinte bilatérale. Tous
les trous maculaires se situaient dans une région d'importante atrophie choriorétinienne
maculaire associée à un staphylome postérieur. On a observé l'entrée de l'artère ciliaire
postérieure à travers la sclère à la base du trou maculaire dans 3 yeux. Enfin, on
a noté la présence d'un schisis recouvrant le trou maculaire ou près de ce dernier
chez 3 patients.
Conclusion
Le trou maculaire constitue un autre signe – bien que rare – d'une dégénérescence
myope. Il apparaît dans les zones d'un staphylome postérieur et se complique d'une
atrophie choriorétinienne prononcée et d'un amincissement de la sclère.
