Insights
This case study details a boy with unilateral eye duplication, a rare congenital malformation. The findings suggest a need for precise terminology to differentiate ocular duplication types.
Area of Science:
- Ophthalmology
- Medical Genetics
- Developmental Biology
Background:
- Unilateral ocular duplication is a rare congenital anomaly.
- Previous literature indicates associated central nervous system malformations and epilepsy.
Observation:
- Presents a case of unilateral ocular duplication followed from birth to 14 years.
- The malformation manifested as synophthalmia within a single orbit.
Findings:
- Literature review confirms compatibility with life, with reported central nervous system issues.
- The specific case involved synophthalmia, a fusion of eyes in one orbit.
Implications:
- Suggests "triophthalmia" is insufficient for classification.
- Proposes differentiating between unilateral synophthalmia and ipsilateral ocular duplication for clarity.
Purpose:
To present a boy with unilateral duplication of the eye.
Method:
The case history is described from the first visit at birth to the age of 14 years.
Results:
A review of the literature shows that this malformation is compatible with life although malformations of the brain and epilepsy have been reported in all cases where a paediatric exam was described. We show that the malformation can appear as a synophthalmic eye in a single orbit or as two separate unilateral eyes in a separate orbit.
Conclusion:
We find the denomination, triophthalmia insufficient to differentiate between the two types and suggest a differentiation between unilateral synophthalmia and ipsilateral ocular duplication.

Gene Duplication and Divergence
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.
