“…Absence of the retina and choroid layers was reported using OCT in our patient. These findings are comparable to what has been reported in the literature [4,[7][8][9][10]. Furthermore, many of macular coloboma cases are associated with other congenital syndromes and disorders [1].…”

Macular coloboma is a rare eye condition that affects around 0.5-0.7/10,000 of live births. Macular coloboma appears as a well-demarcated atrophic lesions that could affect one eye or both eyes on fundus examination. This is a case of a 33-year-old male patient who presented to the outpatient clinic with a history of poor vision in the left eye since childhood. He had a history of strabismus surgery for sensory exotropia (XT) in the left eye. Anterior segment examination of both eyes was normal while the fundus examination of both eyes revealed bilateral chorioretinal lesions in the macula which was larger in the left eye (OS) than the right eye (OD), representing bilateral chorioretinal coloboma. Congenital coloboma is a rare eye condition that leads to non-progressive decrease in visual acuity. Optical coherence tomography (OCT) is the modality of choice in diagnosing and describing macular coloboma.

“…The visual acuity from previous reports1–4,10–12 ranged from light perception to 0.8. However, the atrophic lesions of this case were comparatively smaller than other cases and the conserved normal retinal structures near the fovea resulted in the patient having better visual acuity than those of other cases, although he had exotropia and no stereoacuity.…”

BackgroundCongenital macular coloboma is a rare ocular disease that consists of atrophic lesions in the macula with well-circumscribed borders. We report the findings of spectral domain optical coherence tomography (SD-OCT) at the fixation point in a case of bilateral macular coloboma.Case reportThe subject is a 4-year-old boy. He visited our hospital at age 1 year and 4 months for the evaluation of strabismus. The fundus examination of both eyes showed round-shaped sharply-demarcated atrophic lesions involving the macula with large choroidal vessels and bared sclera at the base. Immunologic tests including toxoplasmosis, rubella, varicella, herpes virus, and human T-cell leukemia virus were all negative. At age 4 years and 1 month, cycloplegic refraction showed insignificant refractive errors and his best corrected visual acuity was 0.6 bilaterally. The SD-OCT showed a crater-like depression accompanying atrophic neurosensory retina, and the absence of retinal pigment epithelium and choroid. Examination of the fixation behavior by visuscope showed steady fixation with an area 0.5° nasal to the nasal edge of the atrophic lesion bilaterally. The SD-OCT findings at fixation area showed remaining normal retinal structures involving inner segment-outer segment (IS/OS) junction line.ConclusionThe findings of SD-OCT have been shown to be useful in the diagnosis of macular coloboma. In the fixation point, the structure of retina and choroid were well preserved.

“…Sharma et al a prouvé histologiquement sur un cas de colobome maculaire que ces zones manquaient de l'épithélium pigmentaire rétinien et de la choriocapillaire [ 2 , 4 ]. L'OCT confirment ces données histologiques, l'ERG global s'il est demandé ainsi que le pattern ERG et l'ERG multifocal sont altérés [ 5 ]. Le diagnostic différentiel d'un colobome maculaire peut se poser devant une toxoplasmose congénitale, une dystrophie maculaire de la Caroline du Nord, une amaurose congénitale de Leber, une dystrophie des cônes à un stade avancé ou une atrophie aréolaire centrale [ 6 ].…”

Le colobome maculaire est une affection congénitale en rapport avec une anomalie de fermeture de la fissure fœtale, pouvant être intégré dans un cadre héréditaire. Il se caractérise cliniquement par une acuité visuelle basse avec une lésion excavée maculaire où le tissu rétinien normal est absent ou rudimentaire et la sclère est ectasique. La tomographie en cohérence optique maculaire est fortement évocatrice du diagnostic et le bilan électrophysiologique s'il est demandé est altéré. Le diagnostic différentiel se pose avec les pathologies entrainant une lésion atrophique et excavée de la macula, particulièrement la toxoplasmose congénitale.
