Picture three retinal layers breaking down together rather than separately — the choroid, the retinal pigment epithelium, and the photoreceptors resting on top of them. That is choroideremia, an X-linked condition that, because of how it is inherited, shows up almost exclusively in males; female carriers usually experience only mild changes that rarely have a meaningful impact on vision.
Patients from Mexico often reach us after a male relative’s fundus exam turned up something a local ophthalmologist flagged as unusual for standard RP — a pattern distinctive enough to warrant genetic confirmation of choroideremia specifically, rather than a broader retinal dystrophy label.

Ocular Symptoms
Night blindness in childhood is usually the opening sign, arriving well before anything else does. Peripheral vision then narrows gradually through the teenage years and into adulthood. What stands out about choroideremia is how long central vision typically holds — often for decades relative to most other inherited retinal diseases — though it can eventually give way in mid-to-late adulthood as the degeneration reaches the macula.
Underlying Causes
The condition comes down to mutations in the CHM gene, located on the X chromosome, which leave cells in the choroid, RPE, and photoreceptor layers short of the REP1 protein they need to survive and function. Because the gene sits on the X chromosome, a carrier mother passes roughly a one-in-two chance of being affected to each son, and roughly a one-in-two chance of carrier status to each daughter
Diagnosis for Mexican Patients
A fundus exam in choroideremia often reveals a distinctive scalloped pattern as the choroid and RPE thin out — combined with electroretinography and OCT imaging, that appearance usually helps distinguish it from other rod-cone dystrophies fairly early. Genetic testing for CHM mutations gives a definitive answer and is especially useful for confirming carrier status in female relatives.

Treatment Approach in India
Because central vision typically stays intact for such a long stretch, care for choroideremia leans heavily on protecting retinal health for as long as that window lasts. Regenerative stem cell therapy is considered for eligible patients as part of that approach, alongside close tracking of how far the degeneration has advanced and low-vision planning ahead of any expected changes to central vision.

Frequently Asked Questions
Why does this condition mostly affect men?
“It comes down to where the CHM gene sits — on the X chromosome. Men carry only one X chromosome, so a single faulty copy is enough to cause the condition. Women carry two, and the healthy copy in carriers is usually enough to prevent significant vision loss, though occasionally very mild changes do show up.
”
As a carrier, is it certain my sons will be affected?
”
Not certain — each son of a carrier mother has roughly a one-in-two chance of inheriting the faulty gene, and each daughter has roughly a one-in-two chance of becoming a carrier. Genetic testing can give a more precise answer for your specific family.”
How would a doctor tell this apart from typical RP just by examining the eye?
“The scalloped pattern of atrophy involving both the choroid and RPE together is fairly distinctive, and an experienced retina specialist can often spot the difference from the more uniform photoreceptor loss seen in classic RP — though genetic testing is what ultimately confirms it.”
When is the right time to start monitoring or discussing treatment?
“Earlier is generally better, since it keeps more options open while central vision is still intact. We would encourage seeking a specialist assessment well before central vision symptoms show up, rather than waiting until they do.”
