Abstract Details



Purpose:

To describe the demographics of patients with Polypoidal Choroidal Vasculopathy in an Asian tertiary eye centre.

Setting:

The study was carried out in a tertiary eye centre at Tan Tock Seng Hospital, National Healthgroup Eye Institute, Singapore.

Methods:

Retrospective review of case notes were performed from January 2015 to December 2016. Data collected included demographics, gender, laterality, presenting eye signs and treatment modalities.

Results:

A total of 45 eyes of 40 patients were reviewed of which 91.1% (41/45) were Chinese, 4.4% (2/45) were Indian and 4.4% (2/45) were Malay. There were 62.2% (28/45) males and 37.8% (17/45) females. The right eye was affected in 48.9% (22/45) of patients while the left eye was affected in 51.1% (23/45). At initial presentation, 31.1% (14/45) eyes had best corrected visual acuity (BCVA) better than 6/12 while 68.9% (31/45) eyes had BCVA worse than 6/12. Improvement in BCVA was seen in 26.7% (12/45) of patient after treatment. Fourty-four percent (20/45) of the presenting eye signs consisted of submacula haemorrhage, 24.4% (11/45) were haemorrhagic pigment epithelial detachment (PED) and 13.3% (6/45) were macula oedema. Treatment modalities included 55.5% (25/45) of focal laser, 28.8% (13/45) of photodynamic therapy (PDT) and 17.7% (8/45) of intravitreal therapy. For patients who underwent PDT, the mean Greatest Linear Dimension was 3118┬Ám. The mean number of intravitreal injections is 9.

Conclusions:

Majority of patients (68.9%) had poor visual acuity at presentation and a significant proportion of them (44.4%) presented with submacula haemorrhage. There were more male than female patients (62.2% vs 37.8%).
