| 본문 : A 39‑year‑old male presented with ocular pain in his right eye following blunt trauma by a plastic ball hitting his eye 1‑day earlier. At initial presentation, his best‑corrected visual acuities (BCVA) was 20/25 in the right eye and 20/20 in the left eye. Slit‑lamp examination revealed no red blood cells in the anterior chamber. Fundus examination revealed no abnormality in the right eye. An orbital computed tomography scan showed a blowout fracture of the right orbital floor with a slight dislocation of the orbital contents. Optical coherence tomography (OCT) scans were performed in both eyes, which were normal, without any signs of retinal detachment. The patient was observed closely with consecutive fundus examination. Two weeks later, he experienced visual disturbance in the left eye. BCVA was 20/50 in the left eye with metamorphopsia while in right eye it was 20/20. On fundus examination, a serous macular detachment was noted in the left eye. Fluorescein angiography showed a focal retinal pigment epithelial (RPE) leakage. OCT performed on the same day showed elevation of the sensory retina in the macula. One month after the trauma in the right eye, BCVA of left eye returned to 20/20 and the neurosensory retinal detachment resolved on OCT examination. Our case shows no immediate ophthalmologic signs in the affected eye from the first visit, but presented CSC in the unaffected eye after few days after trauma; however, there still is a possibility that CSC has occurred regardless of trauma. During the first visit interview, many factors have been considered to rule out other factors that may have caused CSC, i.e. any stressful situation, previous diagnosis of CSC, and use of steroids (oral or any other route); however, none of these factors seemed to cause CSC. Therefore, it may conclude that the trauma in the right eye caused an increase in endogenous catecholamines, affecting the opposite eye. This is the first case of blunt trauma related CSC occurring in the unaffected eye in Korea, and it is important to notice that it took less than 1 month to recover, whereas CSC, in general, is known with its slow recovery. |
