This article analyzes the macular choroidal thickness in normal Taiwanese eyes using enhanced depth imaging optical coherence tomography (EDI OCT). The study includes 295 eyes of 295 normal Taiwanese subjects and examines the relationships between choroidal thickness and various clinical parameters. The results show that age and spherical equivalent refractive error (SERE) have a significant correlation with macular choroidal thickness, while gender and axial length (AL) do not. The study also finds that choroidal thickness decreases with age and is thinner in individuals with myopia. These findings highlight the importance of identifying clinical risk factors for macular choroidal thinning in order to preserve eye vision effectively. [Extracted from the article]

Fluorescein angiography showed disc edema with dye leakage (OD; Figure 1C) and a single point of hyperfluorescence with focal area of retinal pigment epithelium (RPE) decompensation over the temporal superior vessel arcade (OS; Figure 1D). At the visit of six-week follow-up, the disc edema (OD) and the serous detachment (OS) were both reduced (Figure 1E,F) with best corrected visual acuity (BCVA) restored to 20/20 (OD) and 20/25 (OS). (A) Initial fundus photography of the right eye shows optic disc edema. [Extracted from the article]

Purpose Myopic foveoschisis occurs in 9-34% of highly myopic eyes with posterior staphyloma. The pathogenesis is still not fully understood. But the relative inflexibility of the inner retina and a tangential traction induced inward traction force in the posterior staphyloma are possible mechanisms. Conventional internal limiting membrane ( ILM) peeling generally yields good results. However, a postoperative full-thickness macular hole happens in 13-28% of cases. Therefore, this study describes a modified ILM peeling technique named ' ILM maculorrhexis' to minimize the occurrence of postoperative macular hole in patients with foveoschisis. Methods This retrospective case review that included 10 eyes of 10 consecutive patients who underwent vitrectomy with ILM maculorrhexis to treat myopic foveoschisis was studied. After surgery, complete ophthalmic examination and SD-optic coherence tomographic examinations were performed 1, 3, 6, 9 and 12 months postoperatively. Results After surgical intervention, the foveoschisis resolved dramatically in all 10 eyes. The mean central foveal thickness decreased significantly from 840 μ to 273 μ at 12 months postoperatively. Mean Log MAR best-corrected visual acuity improved from 1.04 preoperatively to 0.59 12 months postoperatively. After the follow-up time of at least 12 months, all 10 eyes remained fovea attached, and none of the 10 eyes developed macular hole. Conclusions This technique minimizes traction force over the extremely thinned foveal tissue in highly myopic eyes. In the long-term follow-up of at least 12 months, all 10 cases had good anatomic and visual results. But we still need a larger case number and longer follow-up for further evaluation.
