Predictable signs of benign course of polypoidal choroidal vasculopathy: based upon the long‐term observation of non‐treated eyes

. Purpose:  To find predictable signs of benign polypoidal choroidal vasculopathy (PCV). Methods:  Medical records of 13 eyes from 12 patients who were followed up for 5 years or longer without treatment among 258 consecutive patients with PCV were reviewed retrospectively. The main outcomes measure...

Description
Summary:. Purpose:  To find predictable signs of benign polypoidal choroidal vasculopathy (PCV). Methods:  Medical records of 13 eyes from 12 patients who were followed up for 5 years or longer without treatment among 258 consecutive patients with PCV were reviewed retrospectively. The main outcomes measured were best corrected visual acuity (BCVA) and fundus findings during the follow‐up period. Results:  The average age at presentation was 68 years, and the average follow‐up period after diagnosis was 80 months (range, 62–119 months). The initial mean logarithmic value of the minimal angle of resolution (logMAR) BCVA was 0.28 ± 0.26, and the final mean logMAR BCVA was 0.62 ± 0.72. The difference in the logMAR BCVA values between the two points was not statistically significant (p > 0.05). The trend of change from baseline at 2‐year follow‐up was consistent with those at 5‐year follow‐up in nine eyes. Fundus findings at the initial examination were classified into two patterns: (i) reddish‐orange nodules and detachment of the retinal pigment epithelium with/without detachment of the neurosensory retina (nine eyes); (ii) reddish‐orange nodules alone, or nodules and small subretinal haemorrhage (four eyes). In the eyes with the first pattern, clinical course and visual prognosis were variable. An absence of hard exudates could be a sign to maintain a benign clinical course or stable vision with this pattern. The eyes with the second pattern took a benign clinical course with stable vision. Conclusions:  There is certainly a group of PCV eyes with a benign prognosis. Considering the huge cost and risk of current therapies, the initial ocular findings could be deciding factors that determine the necessity for further treatment.
