Posterior staphyloma-induced serous maculopathy: Evolution and successful treatment with subthreshold micro pulse Laser

Abstract

Purpose

To describe the evolution of posterior staphyloma-induced serous maculopathy (PSISM) in a patient with myopic tilted disc syndrome and its treatment with subthreshold micro pulse laser (SMPL) therapy.

Case description

A 38-year-old male, diagnosed previously with classical features of myopic tilted disc syndrome presented to the retina clinic after 5 years from the initial presentation with blurred vision in the right eye for 6 months, visual acuity of 6/15 and findings of serous macular detachment (SMD) and subretinal precipitates at the upper margin of the posterior staphyloma. Retinal imaging ruled out other causes of SMD such as chronic central serous chorioretinopathy, myopic macular neovascularisation and dome shaped macula. A diagnosis of PSISM was confirmed. The left eye fundus and macula was normal.

Results

Confluent SMPL burns were applied across the SMD. The serous maculopathy resolved over a period of 2 months and visual acuity improved to 6/9. No recurrence of SMD was noted even after 14 months post SMPL.

Conclusion

PSISM develops gradually in eyes with myopic titled disc syndrome. SMPL is a viable therapeutic option in the management of PSISM and should be considered early in the treatment options.
