RHEGMATOGENOUS RETINAL DETACHMENT: A RARE OCULAR MANIFESTATION OF PROTEUS SYNDROME

PURPOSE

To present a case report of a rare ocular manifestation of Proteus syndrome-rhegmatogenous retinal detachment.

METHODS

Retrospective review of the patient's medical record and a review of the literature.

RESULTS

A 16-year-old boy with Proteus syndrome who presented with a total retinal detachment because of an operculated retinal tear. This patient underwent successful surgical repair of the retinal detachment and subsequent cataract surgery.

CONCLUSION

Proteus syndrome may be complicated by the development of rhegmatogenous retinal detachment, which can present in childhood.

Ocular manifestations of genetic skin disorders

Genetic skin diseases, or genodermatoses, often have extracutaneous manifestations. Ocular manifestations in particular can have significant clinical implications, like blindness. Other manifestations, such as the corneal opacities that occur in X-linked ichthyosis, are asymptomatic but characteristic of a particular genodermatosis. Ophthalmologic examination can aid in diagnosis when characteristic findings are seen. The genodermatoses with ocular manifestations will be reviewed, but neurocutaneous, syndromes, genetic pigmentary disorders, and genetic metabolic diseases are not included because they are covered elsewhere in this issue.

Proteus syndrome: report of a case with developmental glaucoma

The purpose of this study was to report developmental glaucoma and pseudopapilledema in a patient with Proteus syndrome. We defined the presence of developmental glaucoma, right pseudopapilledema and myopia in a 4.5-year-old patient with Proteus syndrome. Marked right hemihypertrophy, lipoma, macrodactyly, and asymmetry of the limbs were observed on systemic examination. A cavernoma was also detected in magnetic resonance imaging of the brain. The patient underwent bilateral goniotomy surgery due to glaucoma. The surgical outcomes were satisfactory in both eyes. In conclusions developmental glaucoma and pseudopapilledema might be associated with Proteus syndrome.

Fibrous tumor of the superior oblique tendon in Proteus syndrome

Proteus syndrome is a disorder of patchy, or mosaic, postnatal overgrowth. Mosaic somatic mutation of the AKT1 gene has been identified in over 90% of individuals meeting the diagnostic criteria for Proteus syndrome. Onset occurs in infancy and can involve any tissue of the body. The connective tissue and bone, skin, central nervous system, and the eye are commonly involved. Epibulbar tumors, strabismus, and posterior segment involvement have previously been reported. However, there have not been any reports of lesions affecting the extraocular tendons. We report a case of Proteus syndrome patient presenting with vertical strabismus secondary to a fibrous tumor within the superior oblique tendon. The tumor was successfully excised with complete resolution of the strabismus.
