AIM: To determine the relationship among the macular pigment optical density (MPOD), central macular thickness (CMT) and body mass index (BMI). METHODS: This is a comparative cross-sectional study performed in a single institution. Totally 210 volunteers who met the inclusion criteria were included in this study. The subject’s MPOD was measured using Macula Pigment Screener II (MPS II, by Electron Technology). CMT was measured with Spectral Domain Cirrus Optical Coherence Tomography (OCT), Cirrus (Model 4000, Carl Zeiss Meditec). The information of both MPOD and OCT from both eyes were recorded. The data was analysed using Microsoft® Excel, SPSS, and R (version 3.2.1; R Core Team 2015). RESULTS: There was significant positive correlation between MPOD and CMT (r=0.42, P<0.01) and a significant negative correlation between MPOD and BMI (r=-0.23, P<0.01). CONCLUSION: Our study showed a significant positive correlation between MPOD and CMT. Further study is needed to look at the detailed structure of the fovea and its relationship with MPOD. Our study also found a significant negative correlation between MPOD and BMI, suggesting that a reduction in BMI may increase the density of macula pigment, which can be helpful in preventing age-retinal pigment epitheliitis (ARMD).

Abstract Background Iridocorneal endothelial syndrome (ICE) is a rare disease which happens usually in women at 20-40 years of age. About 50% of patient with such disease develops glaucoma.Case presentation A 29-year-old woman presented in August 2015 with right eye blurring of vision for 6 months. On examination, the corneal endothelial with beaten metal appearance was noted. Right eye correctopia with iris atrophy and periphery anterior synechiae were seen. Mottled appearance of the macula which tallied with the optical coherence tomography (OCT) findings of cystoid macular edema (CME) was found. An non-steroidal anti-inflammatory drugs (NSAIDs) eye drops (NEVANACÒ Nepafenac ophthalmic suspension 0.1%) was commenced for long term. She was re-examined 2 years later in 2018. Her vision was 6/6. OCT and fundus fluorescence angiography (FFA) finding were normal.Conclusion The NSAIDs was the only treatment received by the patient and throughout the years, her CME has subsided. A long term use of Nepafenac 0.1% has shown to be effective in treating CME in ICE syndrome.
