Abstract

PURPOSE
To evaluate the efficacy of anti-vascular endothelial growth factor (VEGF) treatment of eyes with foveal serous retinal detachment (SRD) associated with inferior staphyloma and to investigate choroidal thickness changes following anti-VEGF therapy.
METHODS
In this observational case series, eyes with inferior staphyloma accompanied by foveal SRD were treated with a single intravitreal anti-VEGF injection, followed by further injections as needed. Changes in height and width of subretinal fluid (SRF) and visual acuity after treatment were assessed. Choroidal thickness was measured at the subfovea, 1.5 mm superior and inferior to the fovea using enhanced depth imaging optical coherence tomography at baseline and 1 month after initial anti-VEGF therapy.
RESULTS
Six eyes from six patients were included. One month after the initial injection, the mean SRF height and width had decreased significantly from 112.5 ± 40.1 to 44.5 ± 48.7 µm (p = 0.046) and from 1,401.8 ± 627.3 to 690.7 ± 634.7 µm (p = 0.028), respectively. Mean choroidal thickness at the superior point decreased from 218.7 ± 59.3 to 200.5 ± 61.0 µm (p = 0.046). SRF resolved completely in three of the six eyes (50%) with a mean of 6.8 ± 5.9 injections (range, 1 to 15). All eyes experienced at least one recurrence of exudation, at a mean interval of 4.8 months. Mean visual acuity improvement was 0.17 logarithm of the minimum angle of resolution units at a mean of 28.7 months follow-up.
CONCLUSIONS
Anti-VEGF therapy resulted in an SRF decrease and modest visual improvement in eyes with foveal SRD associated with inferior staphyloma. Reduction in superior choroidal thickness appeared to contribute to the clinical improvements that were observed.
