The primary STD that can cause blindness in later stages if untreated is Syphilis, through a condition called ocular syphilis, which affects the eyes and optic nerve, potentially leading to permanent vision loss. Other STDs, like chlamydia (leading to trachoma in some regions) and gonorrhea, can also cause eye infections and blindness, especially if passed from mother to baby during birth.
Secondary syphilis: This stage occurs after four to 10 weeks of untreated syphilis. In this stage, the eyes are affected in about 10% of people. At this point, ocular syphilis can appear as a rash on the eyelids. The rash can lead to blepharitis, a condition that makes your eyelids inflamed, sore, crusty and red.
According to the CDC, 15 percent of people infected with untreated syphilis reach the late stage, which can occur up to 20 years after initial infection.
Symptoms of chlamydial conjunctivitis can take 2–19 days to appear. People who develop the infection may experience symptoms that can include: watery discharge or pus. itchy, red, swollen, or scratchy eyes.
Herpes simplex viruses 1 and 2 (HSV1 and HSV2) can infect the genitals and eyes. An HSV infection can affect the cornea (the clear dome that covers the front of the eye) and lead to symptoms like watering, redness, blurred vision, and discomfort. In severe cases, it can cause scarring and blindness.
You might think that STIs only affect your reproductive organs, but that's not the case with syphilis. It can affect your eyes, and ocular syphilis can lead to vision loss and even blindness.
What is late-stage chlamydia? Late-stage chlamydia refers to an infection that has spread to other parts of the body. For example, it may have spread to the cervix (cervicitis), testicular tubes (epididymitis), eyes (conjunctivitis), or throat (pharyngitis), causing inflammation and pain.
Chlamydial conjunctivitis is often a unilateral disease but can involve both eyes. Patients complain of pink/red eye, mucous discharge, crusting of lashes, lids stuck together, swollen lids, tearing, photophobia, foreign body sensation, and decreased vision.

HIV (10+ years)
Human immunodeficiency virus (HIV) is one of the most well-known examples of an STD that can lie dormant.
The general rule is: The quicker you treat it, the better. However, the fact that you have had chlamydia for several years does not necessarily mean that you are infertile. Many people carry the bacteria for a long time without suffering consequences.
There are four stages of syphilis (primary, secondary, latent, and tertiary). Each stage has different signs and symptoms.
Ocular involvement is an important manifestation of syphilis which may result in blindness. Our data demonstrate outcomes for ocular syphilis are poor if detected late; early recognition and diagnosis is therefore vital to avoid permanent visual loss.
Signs and symptoms of late stage tertiary syphilis include:
Ocular syphilis can be cured
If you are allergic to penicillin, your doctor will prescribe a different antibiotic. In certain cases, your ophthalmologist may also prescribe oral and/or topical steroids to control inflammation in the eyes.
Chlamydia and gonorrhea can cause conjunctivitis, leading to redness, itchiness, and discharge. They may also bring blurred vision due to mucous or pus, and sensitivity to light.”
Most people with chlamydia do not notice any symptoms and do not know they have it. In the eyes, chlamydia can cause irritation, pain, swelling and discharge similar to conjunctivitis. These symptoms continue for several weeks until treatment is started.
Chlamydia can cause eye infection, such as inclusion conjunctivitis or trachoma, and if left untreated, it could lead to permanent damage like corneal scarring and blindness. Chlamydia can also cause trachoma, which is responsible for over 6 million cases of blindness worldwide.
Trachoma is the leading preventable cause of blindness worldwide. Most trachoma cases occur in poor areas of Africa, where 85% of people with active disease reside. In areas where trachoma is prevalent, infection rates among children under 5 can be 60% or more. Early treatment may help prevent trachoma complications.
Visible signs in women:
Discharge – chlamydia doesn't normally cause signs that you can see on the skin of the vulva. Often however, there may be a change in vaginal discharge – changes are very variable, but usually there is more discharge than usual, and it may be mucousy, stringy or even blood stained, with pus.
C. trachomatis prevalence among suspected keratitis patients was 8.7 %. Infection rates were 11.4 % in females and 6 % in males.
Symptoms of Chlamydia trachomatis infection can include:
If left untreated, chlamydia can cause pelvic inflammatory disease (PID) in people with a vagina and lead to chronic pain and infertility. In people with a penis, untreated chlamydia can cause pain and swelling in one or both testicles.
Most people who have chlamydia do not have any symptoms. If you do get symptoms they can start from 1 week to several months after infection.
An eye infection caused by chlamydia bacteria will cause the same symptoms as other bacterial eye infections. These include: redness. discharge (is often present when waking up in the morning)
