SINGAPORE — A Singaporean man in his 30s says he was turned away from Sengkang Polyclinic without being clinically assessed, only to be diagnosed hours later with a serious corneal ulcer that required urgent treatment to reduce the risk of permanent vision loss.
The incident, reported by Mothership on Aug. 25, has raised questions about how walk-in patients with potentially urgent symptoms are screened when appointment slots are already full. SingHealth Polyclinics, however, says patients requiring urgent medical attention are supposed to receive prompt assessment and care.
Patient Says Severe Eye Pain Began on Aug. 13
The patient, identified by Mothership under the pseudonym “Bob,” said he developed eye pain on Aug. 13, 2026.
By that morning, he was also experiencing severe sensitivity to light, known as photophobia, and said the discomfort was intense enough that he was wearing sunglasses indoors.
At 8:58 a.m., he reportedly called SingHealth’s booking line seeking a same-day consultation at Sengkang Polyclinic, the facility closest to him.
He was told the clinic’s appointment slots were full and that Punggol Polyclinic still had availability.
Because of his symptoms and his preference to seek treatment nearby, he initially declined the Punggol appointment and instead went directly to Sengkang Polyclinic.
He Claims No Clinical Triage Took Place
According to Bob, when he arrived at Sengkang Polyclinic at around 9 a.m., he was stopped at the registration counter before receiving a queue number.
He alleged that no one asked him about his symptoms and that he was not assessed by clinical staff.
He said he was instead told the clinic had too many patients and that he should return the following day.
That allegation has become the central issue in the case because delaying assessment of certain acute eye conditions can carry serious consequences.
SingHealth Polyclinics later told Mothership that it had reviewed the matter but was unable to establish the details of the interaction that allegedly took place at triage.
A Second Attempt Led to an Urgent Referral
After leaving Sengkang Polyclinic, Bob called the booking line again and accepted the available noon appointment at Punggol Polyclinic.
He was examined at around 12:30 p.m.
This time, the doctor considered his condition urgent and referred him directly to Singapore General Hospital’s Emergency Department.
He was subsequently assessed at the Singapore National Eye Centre, where doctors diagnosed him with a corneal ulcer.
According to Bob’s account, he was told treatment within 24 to 48 hours was critical to preventing permanent vision loss.
Why a Corneal Ulcer Can Become Serious Quickly
The cornea is the transparent tissue covering the front of the eye. Infections involving the cornea can be caused by bacteria, fungi, parasites or viruses.
SingHealth says bacterial infections are the most common form of corneal infection in Singapore.
Common warning signs include sudden eye pain, redness, swelling, tearing, discharge and blurred vision. SingHealth also says contact lens-related infections are the most common cause of corneal infections locally, although infections can also follow eye injuries or occur in people with existing corneal conditions.
Singapore National Eye Centre advises people to seek immediate medical attention when eye pain is persistent or severe, particularly if it is accompanied by decreased vision.
Severe infections can require intensive antibiotic or other anti-infective eye drops, sometimes administered hourly. In advanced cases, complications can include corneal thinning, perforation and scarring, and some patients may ultimately require a corneal transplant.
SingHealth: Patients Should Not Be Denied Care Just Because Slots Are Full
SingHealth Polyclinics clinic director Chang Zi Ying told Mothership that the institution was aware of the complaint and had responded to the patient.
She said patients are encouraged to make appointments before visiting polyclinics as part of efforts to manage waiting times and overcrowding.
For walk-in patients, SingHealth said the next available consultation may be offered later the same day. If all slots are filled, the appointment could be scheduled for the following day, or patients may be advised to visit a nearby Community Health Assist Scheme GP clinic.
But SingHealth stressed one key exception: urgent cases.
“Patients will not be denied care solely because the polyclinic has reached its appointment capacity,” Chang said, adding that patients showing urgent symptoms or experiencing medical emergencies should be attended to promptly.
SingHealth’s own public guidance also advises patients experiencing pain over the eyes to seek emergency-department care where emergency eye services are available.
Patient Disputes SingHealth’s Account
Bob later filed a written complaint with SingHealth Polyclinics.
According to emails reviewed by Mothership, SingHealth said it had attempted to clarify what happened during the patient’s visit but was unable to establish the details of the interaction.
SingHealth also said it had tried to contact him by telephone to discuss the complaint.
Bob disputed that account, saying he did not receive the call and arguing that there had been no triage interaction in the first place.
He also asked whether CCTV footage from the registration area had been examined during the review.
SingHealth subsequently requested a phone discussion, but Bob said he wanted disputed points answered in writing first and requested that any later telephone conversation be recorded.
The Bigger Question Is About Triage, Not Appointment Capacity
The case highlights an important distinction in crowded healthcare settings: appointment availability and medical urgency are not necessarily the same thing.
A patient without an appointment may legitimately face a longer wait or be redirected to another facility. But symptoms that could indicate a time-sensitive emergency may require clinical screening before that decision is made.
That is particularly significant with acute eye conditions, where severe pain, visual disturbance or rapidly worsening symptoms can sometimes signal problems requiring immediate attention.
SNEC states that people with urgent or emergency eye problems should seek emergency medical care rather than rely on its normal outpatient appointment process.
For Bob, the outcome could have been considerably different had he simply returned home and waited until the next day, according to the medical urgency described in his account.
The unresolved question now is whether his experience represented an isolated communication breakdown — or exposed a gap between SingHealth’s stated triage policy and what can happen at the front counter when clinics are under pressure.
