PURPOSE To describe and evaluate demographic, clinical features, prognostic factors, and rate of success of surgery and visual outcomes in patients with late presentation of retinal detachment. METHODS A retrospective, comparative, observational case series of patients with late presentation retinal detachment, defined as retinal detachment with the loss of central vision for 4 weeks or more, over a period of 12 months. RESULTS The mean of onset of central visual loss was 12.7 weeks (SD, 21.3). Proliferative vitreoretinopathy at the first operation was identified in 69% of eyes. The overall primary success rate was 69.2%, significantly less than that was found in outcomes for nonselected retinal detachment (primary success rate, 86%; P = 0.006). The initial best-corrected visual acuity was 20/500, and the final was 20/160 (P = 0.0027). There were no identifiable statistically significant socioeconomic factors related to late presentation. CONCLUSION A high rate of established proliferative vitreoretinopathy on presentation was identified, and although cases can be treated with good anatomical results, visual outcomes are often less favorable. Primary surgical success is lower, and more reoperations are required compared with standard retinal detachments.

Purpose This study aimed to describe the choroidal features of ocular amyloidosis using multimodal imaging, to correlate these findings with systemic involvement, and to propose a choroidal grading system. Methods Eleven patients with systemic amyloidosis were reviewed retrospectively. Each case was assigned a grade according to the severity of choroidal findings as determined by both enhanced depth imaging optical coherence tomography and indocyanine green angiography. The severity of systemic amyloidosis was then correlated with the choroidal involvement. Results On indocyanine green angiography, all patients exhibited hyperfluorescent spots in the late stage and were classified according to preexisting criteria. On enhanced depth imaging optical coherence tomography, hyperreflective foci were seen in the choriocapillaris and Sattler's layer in Grade 1, partial loss of Sattler's layer was additionally seen in Grade 2, and a dense hyperreflective Haller's layer was seen in Grade 3. Choroidal grading scores were significantly correlated with the systemic severity score (P = 0.0014, Pearson's correlation coefficient; ρ = 0.83). Conclusion With ocular amyloidosis, evaluation of choroidal characteristics using multimodal imaging may serve as a biomarker for systemic involvement.
