A 40-year-old woman presented with ocular discomfort in both eyes that had persisted for several months. Six months ago, she had undergone a bilateral nasal and temporal conjunctivectomy using a bare scleral technique followed by a postoperative application of 0.02% mitomycin C (MMC) to treat her chronic hyperemic conjunctiva for cosmesis. Slit-lamp examination revealed that the patient had bilateral nasal and temporal scleral thinning, and a calcified plaque on her nasal conjunctiva. There was no episcleral tissue present around the wound area, and it was difficult to detect any normal conjunctival tissue in the adjacent area for covering the lesion. We believe that performing an aggressive conjunctival excision procedure followed with MMC application for cosmetic enhancement may be disastrous in certain cases.

PURPOSE: To evaluate clinical characteristics and the macular gradient in myopic posterior staphyloma with time domain (TD) optical coherence tomography (OCT). METHODS: Sixty-four staphyloma eyes of 40 patients were examined. Macular gradient (tangent theta) and the location of staphyloma were assessed with OCT imaging. The macular gradient was measured at points 1 mm and 2 mm distant from the fovea. The relationships of the macular gradient with age, axial length, and spherical equivalent were analyzed. RESULTS: In 8 eyes (12.5%), the bottoms of the staphylomas were in the fovea, and there was no macular gradient. However, in the other 56 eyes (87.5%), the bottoms of the staphylomas were not in the foveal area, and macular gradients existed. Staphylomas were commonly located in the infero-nasal retinal area. The mean macular gradient (tangent theta) was 0.26 +/- 0.08 at 1 mm distance from the fovea and 0.28 +/- 0.10 at 2 mm. No significant relationships were observed between macular gradient and axial length, patient age, or spherical equivalent. CONCLUSIONS: TD OCT reveals staphyloma location. If the location is outside of the fovea, a macular gradient exists and can be measured by OCT. Axial length measurement error may occur in eyes with poor visual fixation and steep macular gradients.
