While retinal detachment itself is not a contagious condition, the underlying structural vulnerabilities that lead to it often run in families. In the UK, if an individual has suffered a retinal detachment, it is a sensible and proactive measure for their close biological family members to undergo a comprehensive dilated eye examination. This is particularly important if the detachment was caused by hereditary conditions such as high myopia, lattice degeneration, or rare genetic syndromes like Stickler syndrome. While a routine “puff of air” or basic sight test is insufficient, a specialist retinal check can identify “silent” tears or weak spots in family members before they progress to a detachment. Understanding the familial link in retinal health allows for preventative care that can protect the sight of siblings, children, and parents.

The hereditary link of high myopia
One of the most common reasons for retinal detachment in the UK is high myopia (severe short sightedness). High myopia is strongly hereditary; if one or both parents have a very strong glasses prescription, their children are significantly more likely to develop the same condition. In a highly myopic eye, the eyeball is physically longer than average, which causes the retinal tissue at the back to be stretched thin.
This thinning makes the retina much more prone to developing holes and tears. If a family member has had a detachment due to myopia, their siblings and children should have a dilated eye exam to assess the thickness and integrity of their own retinas. According to the College of Optometrists clinical management of myopia, early monitoring of these high-risk relatives is a key part of long-term sight preservation.
Genetic syndromes: Stickler and Wagner syndrome
In some cases, retinal detachment is a primary symptom of a rare genetic disorder. The most well-known of these in the UK is Stickler syndrome, a connective tissue disorder that affects the collagen in the eye, ears, and joints. Individuals with Stickler syndrome have a very high lifetime risk of retinal detachment, often occurring at a young age.
If a patient is diagnosed with Stickler syndrome following a detachment, UK clinical protocols suggest that all first-degree relatives (parents, siblings, and children) should be screened. This is because the condition can vary in severity; one family member might only have mild joint pain, while another is at high risk of sudden vision loss. Identifying these cases early allows for “prophylactic” (preventative) treatment. Research regarding Stickler syndrome and retinal management emphasizes that family screening in these specific cases is a vital public health intervention.
Lattice degeneration and familial weak spots
Lattice degeneration is a condition where the peripheral retina becomes thin and develops a “criss-cross” pattern of white lines. While it does not always lead to a detachment, it is a known precursor and is found in about eight to ten per cent of the general population. There is a clear familial tendency for lattice degeneration; if you have it, there is a higher chance your siblings or children do too.
During a family screening, an optometrist or ophthalmologist will look specifically for these “lattice” areas. While many areas of lattice do not require treatment, identifying them allows the clinician to provide “red flag” education to the family member. They will know exactly what symptoms to look for and will be monitored more frequently than someone with a standard retina. This secondary prevention is a cornerstone of NHS retinal health pathways.
What a family screening involves
A screening for retinal risk is more involved than a standard trip to the optician. In the UK, this should be a “dilated fundus examination.” This means the clinician will use eye drops to widen the pupils, which usually takes about twenty minutes to work. This wide view is essential because most familial tears occur in the far periphery of the eye, which is hidden when the pupil is small.
The clinician may also use a wide field retinal camera (such as an Optus) to create a permanent digital map of the relative’s retina. This image acts as a baseline, allowing the specialist to spot even the smallest changes in subsequent years. If a family member is found to have an “asymptomatic” (painless and silent) tear during this check, they may be referred for preventative laser treatment to secure the area.
The role of preventative laser for relatives
If a family member is found to be at exceptionally high risk during a screening, a consultant may discuss prophylactic laser retinopexy. This is a preventative treatment where a laser is used to “weld” the retina around a weak spot or a small hole. This is most common in families with a history of multiple detachments or known genetic syndromes.
In the UK, the decision to perform preventative laser is made on a case-by-case basis. The surgeon balances the risk of the laser procedure against the risk of a future detachment. For most relatives, regular monitoring is sufficient, but for those with clear “red flags,” the laser provides a permanent safety net. Information provided by Moorfields Eye Hospital on familial eye checks highlights that early intervention in at risk relatives is a highly effective way to prevent the need for major emergency surgery later in life.
When to seek genetic counselling
If several members of a family have suffered from retinal detachments or other eye issues like early onset cataracts or glaucoma, a referral to a genetic counsellor may be appropriate. In the UK, this is usually managed through the NHS Regional Genetics Service. A genetic counsellor can help determine if there is an underlying inherited condition and can coordinate testing for the rest of the family.
This is particularly useful for planning for future generations. If a specific genetic mutation is found, children can be screened from a very young age, ensuring they receive the necessary monitoring before they are even old enough to report visual symptoms. This level of preventative care represents the “gold standard” of UK ophthalmic genetics, focusing on family wellness rather than just individual treatment.
| Factor | Should Family Be Screened? | Urgency |
| High Myopia (-6.00 or more) | Yes | Recommended annually |
| Known Stickler Syndrome | Essential | High (Urgent referral) |
| Simple Aging Detachment | Optional | During routine eye check |
| Lattice Degeneration | Yes | Recommended every 1 to 2 years |
| Traumatic Detachment | No | Standard check remains fine |
Conclusion
Family members should be screened for retinal detachment risk if there is a history of high myopia, lattice degeneration, or known genetic syndromes within the family. While the detachment itself is not inherited, the structural weaknesses that cause it often are. A dilated eye examination for first degree relatives allows for the early detection of tears and the use of preventative laser treatment where necessary. By maintaining family wide awareness of retinal health, you can ensure that those at high risk receive the specialist monitoring they need to protect their sight. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Does my child need a check if I had a detachment?
If your detachment was due to high myopia or a genetic condition, your child should have a dilated eye exam by the age of five to ten to establish a baseline.
Can my local optician do a “family screening”?
Yes, most UK optometrists can perform a dilated retinal check; just be sure to inform them of the specific family history so they can look extra carefully at the periphery.
Is Stickler syndrome common in the UK?
No, it is a rare condition, but it is one of the most common causes of inherited retinal detachment, so it is always considered when multiple family members are affected.
What if my detachment was caused by an injury?
If the detachment was purely traumatic (e.g., a sports injury), your family members are not at a higher risk and do not need special screening.
Will my siblings need laser treatment too?
Not necessarily; most relatives will only need regular monitoring. Laser is only used if a clear and dangerous tear is found during the check.
Can a genetic test predict a retinal detachment?
A genetic test can identify syndromes that increase the risk, but it cannot predict exactly if or when a detachment might occur.
Are these family checks covered by the NHS?
If a relative has a history of a serious eye condition like a detachment, you may be eligible for an NHS funded eye exam; check with your local optician.
