Purpose: To determine the influence of morphologic classification based on optical coherence tomography (OCT) on epiretinal membrane (ERM) surgery outcomes. Methods: We retrospectively reviewed the medical records of 77 eyes with ERM treated by vitrectomy with ERM peeling. By using OCT, the preoperative ERM was classified into four types: diffuse (DIF), cystoids macular edema (CME), pseudolamellar hole (PLH), and vitreomacular traction (VMT). The postoperative changes of central macular thickness (CMT) and best-corrected visual acuity (BCVA) were compared. Results: Approximately six months postoperatively, the DIF type had the best BCVA for both idiopathic and secondary ERM, followed by the PLH, CME, and VMT types. On the other hand, regarding the mean BCVA improvement, the VMT type was the best, followed by the DIF, PLH, and CME types. When comparing the difference in BCVA improvement by each type, idiopathic ERM showed a clearer distinction when the inner segment/outer segment (IS/OS) junction was not disrupted. Conclusions: BCVA improvement was significantly different depending on the morphologic classification of ERM by using OCT. Especially in cases of ERM with an intact IS/OS junction, the morphologic classification can help predict surgical outcomes. J Korean Ophthalmol

Purpose: To evaluate the findings of carotid ultrasonography performed on patients with retinal vascular disease and to determine the risk of cardiovascular disease and association of retinal vascular disease and cardiovascular disease. Methods: From December 2009 to May 2012, patients diagnosed with central retinal artery occlusion (CRAO, n = 18), central retinal vein occlusion (CRVO, n = 23), and branch retinal vein occlusion (BRVO, n = 68) underwent carotid ultrasonography. We evaluated the intima-media thickness (IMT) of the common carotid artery (CCA) and the internal carotid artery (ICA), stenosis and the number of plaques, and then compared these results with those of a healthy control group (n = 221). Results: The mean CCA-IMT and ICA-IMT were significantly higher in the CRAO and BRVO groups compared with the control group. On the contralateral side, CCA-IMT was increased in the CRAO, BRVO, and CRVO groups and ICA-IMT was increased in the CRAO and BRVO groups compared with the control group. Contralateral CCA stenosis was higher in the CRVO group (9.1%) and ipsilateral ICA stenosis in CRAO group (21.7%) was significantly higher than that of the control group. Plaque was observed better in all groups compared with the control group. The proportion of patients risk for cardiovascular disease, i.e. those who had IMT thickenesses more than 1.0 mm, was higher in the CRAO and BRVO groups compared with the control group. Conclusions: The carotid ultrasound findings of patients with retinal vascular diseases showed increased IMT and plaque. The group of patient at risk for cardiovascular disease, which was defined with carotid artery IMT, was higher in patients with retinal vascular disease. Therefore, in patients with retinal vascular disease, carotid artery ultrasonography and the overall management and treatment of cardiovascular disease are necessary.

Purpose: To report a case of congenital idiopathic microcoria corrected with pupilloplasty and amblyopia treatment. Case summary: A 4-year-old girl was referred for pupillary abnormality of the left eye. Her mother experienced no problems during gestation, and the patient was born at full term. On initial examination, visual acuity was 20/25 in the right eye and counting finger at 50 cm in the left eye. Slit lamp examination revealed that the left pupil was displaced superonasally. A band of fibrous tissue extended across the left pupil and there was no red reflex. There was very slight reaction to mydriatics. Using 23-gauge vitrectomy scissors, a pupilloplasty was performed, and the synechiae are removed. Postoperatively, the pupillary light reflex was brisk, and occlusion therapy was initiated. After 3 months, the visual acuity of the left eye improved to 20/30. Conclusions: In our case, although microcoria was diagnosed at a relatively old age, the patient’s clinical features were consistent with congenital idiopathic microcoria. Therefore, we diagnosed the patient with gradually progressed congenital idiopathic microcoria. In the case of typical congenital idiopathic microcoria, the red-reflex is absent at birth because of the small pupil. However, as in our case, it is possible that the pupil can contract gradually due to movement of the fibrous strand. The point must be considered in such patients.

Purpose: To compare the surgical outcomes of 23-gauge transconjunctival sutureless vitrectomy (TSV) with silicone oil tamponade versus 20-gauge PPV with sclera buckling (SB) and SF6 gas tamponade for the repair of rhegmatogenous retinal detachment (RRD) with inferior breaks. In addition, silicone oil tamponade was evaluated as an alternative option for patients with inferior RRD. Methods: Two different types of surgery were performed on two groups of patients with inferior RRD: 23-gauge TSV with silicone oil tamponade (group 1) and 20-gauge PPV with SB and SF6 gas tamponade (group 2). The preoperative clinical features, anatomical success rate, complications, functional outcomes (visual acuity, VA, intraocular pressure, IOP), and surgical time were retrospectively evaluated. Results: The primary surgical success rates were 94% and 78% in groups 1 and 2, respectively. The final success rate was 100% in both groups. Therefore, in terms of success rate, there was no difference between the two groups. No statistically significant difference in IOP change or complication rate was observed between the two groups. VA change was significantly better and surgical time was shorter in group 1. Conclusions: No statistically significant difference of anatomical success rate or complication rate between 23-gauge TSV with silicone oil tamponade and 20-gauge PPV with SB and SF6 gas tamponade was found for inferior RRD. However, surgical time was shorter in group 1. A 23-gauge TSV with silicone oil tamponade could be an alternative to 20-gauge PPV with SB and SF6 gas tamponade for patients with inferior RRD, especially patients who cannot maintain a prone posture.

새만금 방조제의 효율적인 유지관리를 위하여 다양한 방법들이 적용되고 있으나 제체 인도부 및 도로부 일부 지점에서 발생하는 공동에 대해서는 육안으로 확인이 불가능하다. 공동으로 인한 균열 및 침하를 사전에 탐지할 수 있는 기술이 필요하며 이미 발생한 균열 및 침하구간에 대해서도 하부 공동규모의 확장여부에 대한 모니터링이 필요하다. 본 연구는 육안조사 위주로 진행되고 있는 방조제 유지관리의 한계점을 극복하기 위하여 천부구간에 공동 및 지반이완대를 탐지할 수 있는 GPR탐사를 실시하고 심부구간에는 전기비저항탐사, MASW탐사 등 비파괴 물리탐사 기법을 이용하여 침하나 함몰현상들을 사전에 방지하고 효율적인 관리를 도모하고자 한다. 또한 방조제 해측사면에서 발생하는 함몰 및 유실현상에 대해서도 드론 영상촬영 및 전자탐사를 실시하여 이상대를 확인하고 지속적으로 모니터링 함으로써 방조제의 효율적인 유지관리와 구조적으로 취약한 구간에 대한 대책을 체계적으로 수립하는데 큰 역할을 할 수 있을 것으로 기대된다.
