Purpose: To determine the clinical significance of choroidal thickness and evaluate changes in choroidal thickness over time in eyes affected by ocular ischemic syndrome (OIS).Methods: Medical records of 16 patients diagnosed with OIS between November 2017 and August 2019 were retrospectively reviewed. In every nine areas of the Early Treatment Diabetic Retinopathy Study grid, we compared the differences in choroidal thickness between the eyes with OIS and unaffected eyes, and its change in the OIS eyes during the follow-up period using swept-source optical coherence tomography. We analyzed the best-corrected visual acuity, intraocular pressure, fluorescein angiography (FAG) parameters, systemic diseases, and the duration of symptoms. Correlation between FAG parameters and the choroidal thickness value ratio in the OIS eyes and the unaffected eyes, and changes in the choroidal thickness in the OIS eyes during follow-up were investigated.Results: Median age of the subjects was 67.5 years. In the OIS eyes, all FAG parameters were delayed at the initial examination. Best-corrected visual acuity and intraocular pressure were significantly different between the OIS and unaffected eyes. While the choroidal thickness in every nine areas of Early Treatment Diabetic Retinopathy Study in the OIS eyes was lesser than the unaffected eyes, the choroidal thickness of inner temporal, outer nasal, and outer temporal area showed statistically significant difference. During follow-up, changes in choroidal thickness of OIS eyes as well as correlation between the FAG parameters and the choroidal thickness value ratio between the OIS eyes and the unaffected eyes were not found to be statistically significant.Conclusions: The choroidal thickness of the eyes with OIS was significantly less compared with the unaffected eyes. We inferred that choroidal thinning takes place in the early phase of the disease as the changes in choroidal thickness during the follow-up period were not significant.

During pregnancy, cardiac output increases and hormone levels fluctuate. These physiological changes in pregnant women often cause retinal and choroidal diseases or worsen preexisting retinal and choroidal conditions [1,2]. For example, the incidence of central serous chorioretinopathy (CSC) and circumscribed choroidal hemangioma (CCH) increase during pregnancy [3,4]. Specifically, these diseases become exacerbated during the third trimester and spontaneously regress after childbirth [5,6]. Here, we present a case of a pregnant woman with a choroidal mass causing serous retinal detachment (SRD) during the first trimester of pregnancy that resolved spontaneously after an abortion. Case This study was approved by the Institutional Review Board of the Keimyung University Dongsan Hospital (IRB No: DSMC 2020-02-070). The patient provided written informed consent for publication of clinical details and images. A 40-year-old woman was referred to our hospital with a 3-day history of visual disturbance in her left eye. The patient was a primigravida who was in her first trimester of pregnancy (7 weeks) at the time of referral. She did not have gestational hypertension or diabetes. Her left eye initially had a best-corrected visual acuity (BCVA) of 20/50 (according to the Snellen chart) and an intraocular pressure (IOP) of 15 mmHg. Her right eye had a BCVA of 20/20 and an IOP of 17 mmHg. Examination of the fundus revealed an orange-red retina in the left eye with posterior pole elevation (Fig. 1A). Optical coherence tomography (OCT; DRI OCT Triton, Topcon, Tokyo, Japan) revealed a thick (> 500 µm) elevated choroid, an SRD, compression of the choriocapillaris, and a choroidal mass located between the choriocapillaris and the outer choroidal tissue in the left eye (Fig. 1B). We avoided fluorescein angiography (FA) and indocyanine green angiography (ICGA) because of their possible teratogenicity. The patient was diagnosed with a choroidal mass. The appearance of the mass suggested possible Pregnancy-related ocular diseases develop mostly in the third trimester of pregnancy. Here, we describe a case of a pregnant woman with a choroidal mass that caused a serous retinal detachment during the first trimester of pregnancy. The patient's condition resolved spontaneously after an abortion.

Purpose:To evaluate the relation between ocular biometry and anthropometric parameters in Korean adults with cataracts. Methods:The preoperative medical data of 150 eyes (150 patients) who underwent cataract surgery from November 2015 to March 2016. Anthropometric parameters include height, weight and body mass index (BMI). Ocular biometry includes axial length, anterior chamber depth, corneal curvature, lens thickness and central corneal thickness. The relation between ocular biometry and anthropometric parameters was evaluated using linear regression analysis. Results: The mean age was 67.44 ± 10.83 years. The mean height, weight and BMI were 157.24 ± 9.16 cm, 60.50 ± 10.18 kg and 24.47 ± 3.59 kg/m 2 . The mean axial length, anterior chamber depth, corneal curvature, lens thickness and central corneal thickness were 23.51 ± 0.80 mm, 3.23 ± 0.42 mm, 44.49 ± 1.33 diopter, 4.44 ± 0.42 mm and 534.64 ± 31.90 μm. The height showed a significant positive relationship with axial length and anterior chamber depth and a significant negative relationship with average corneal curvature. However, there was no significant relationship with the central corneal thickness or lens thickness. The weight showed significant positive relationship with axial length. BMI was not related to any anthropometric parameters. Age showed a significant positive relationship with average corneal curvature and lens thickness and a negative relationship with height and anterior chamber depth. Conclusions: As height increases, the axial length and the anterior chamber depth increase and the corneal curvature become flatter. As age increases, the anterior chamber depth becomes shallower, the corneal curvature becomes steeper and the lens thickness increases.

Purpose:To report a case of visual deterioration and atrophied retina after pars plana vitrectomy (PPV) and silicone oil tamponade for the treatment of retinal detachment with previous encircling scleral buckling. Case summary: A 29-year-old female visited for treatment of rhegmatogenous retinal detachment (RRD) in the right eye which was not completely resolved after encircling scleral buckling. Logarithm of minimal angle of resolution (log MAR) and best corrected visual acuity (BCVA) was 0.3. Retinal detachment from 3 to 8 O'clock without macular involvement was identified. Pars plana vitrectomy, endophotocoagulation and silicone oil tamponade were performed. During the operation, retinal dialysis and retinal break at the superonasal periphery were observed. The patient complained of central scotoma at 2 days postoperatively and hyper-reflection of the inner retina was identified on optical coherence tomography (OCT). At 2 weeks postoperatively, the OCT image revealed a thin retina and impending macular hole. After 2 months, the silicone oil was removed. Although the retina was well attached, the retina remained atrophied and the log MAR BCVA was 0.16. Conclusions: We report a rare case with deteriorated visual acuity after PPV and silicone oil tamponade for the retreatment of RRD in an atopic dermatitis patient.
