Dyskeratosis congenita is a group of rare genetic bone marrow failure syndromes. Revesz syndrome, a variant disorder, is characterized by retinopathy, aplastic anemia, nail dystrophy, and cerebellar hypoplasia. We report the case of an 11-month-old boy with bilateral cicatricial retinal detachments associated with fibrovascular proliferation. Genetic testing ultimately confirmed a diagnosis of Revesz syndrome, which can mimic cicatricial retinopathy of prematurity. Prompt referral to a hematologist expedites diagnosis and treatment.

Telomeres protect the ends of chromosomes but shorten following cell division in the absence of telomerase activity. When telomeres become critically short or damaged, a DNA damage response is activated. Telomeres then become dysfunctional and trigger cellular senescence or death.

Dyskeratosis congenita (DC) is a rare telomerase disorder affecting high turnover cells. Malfunction of protective proteins in DC results in patient genomes with shortened germline telomeres leading to genetic instability, cellular apoptosis, and overall cellular lifespan degradation. Classically, reports of DC described a triad of dysplastic nails, reticular skin pigmentation, and oral leukoplakia.

Background: Dyskeratosis congenita (DC) is a multisystem syndrome characterized by mucocutaneous abnormalities, bone marrow failure, and predisposition to cancer. Studies over the last 25 years have led to the identification of 18 disease genes. These have a principal role in telomere maintenance, and patients usually have very short/abnormal telomeres.

We report the case of a 2-year-old male child, initially treated with bilateral laser photocoagulation for retinopathy of prematurity. He developed exudative changes in the right eye, presumed to be Coats disease.
