Effect of Serous Retinal Detachment on the Measurement of Axial Length in Central Serous Chorioretinopathy

PURPOSE: To evaluate the changes of axial length (AXL) in eyes with unilateral idiopathic central serous chorioretinopathy (CSC) after resolution of serous retinal detachment. METHODS: A total of 31 patients diagnosed with idiopathic unilateral CSC were included in this study. The changes of AXL according to serous retinal detachment were examined. The keratometric value and AXL were measured using partial coherence interferometry. Serous retinal detachment and central macular thickness (CMT) were measured by spectral domain optical coherence tomography. RESULTS: The mean age of the 31 CSC patients, including 19 males, was 42.7 years. The AXL was significantly increased from 23.41 to 23.58 mm after resolution of serous retinal detachment (p < 0.001). The CMT was significantly decreased from 413.4 to 226.8 µm after resolution of serous retinal detachment (p < 0.001). The differences in AXL correlated with CMT differences and subretinal fluid height (r = −0.616, p < 0.001 and r = −0.637, p < 0.001, respectively), and the best-corrected visual acuity was significantly different after resolution of serous retinal detachment (p < 0.001). CONCLUSIONS: In unilateral idiopathic CSC with serous retinal detachment, a shortened AXL in the acute phase was restored after resolution of serous retinal detachment.

Influences on Astigmatism and Corneal Endothelium Using Two Different Incision Sizes and Mode of Phacoemulsification

PURPOSE: To compare surgically induced astigmatism and influences on the corneal endothelium in phacoemulsification by Ozil(R) and Hyperpulse mode of Infiniti(R) using 2 different corneal incision lengths of 2.2 mm and 2.8 mm. METHODS: The patients were grouped by the mode of phacoemulsification and incision size as follows: Ozil(R) mode with 2.2 mm incision group (n = 29), and 2.8 mm incision group (n = 30); Hyperpulse mode with 2.2 mm incision group (n = 29), and 2.8 mm incision group (n = 30). The surgically induced astigmatism, central corneal thickness and endothelial cell density were measured up to 2 months after surgery and the efficiency of 2 modes compared by measuring average phacoemulsification times. RESULTS: There was no significant difference in the surgically induced astigmatism, central corneal thickness, endothelial cell density, best corrected visual acuity and average phaco power among 4 groups. The cumulated dissipated energy (CDE) using Ozil(R) mode was lower than Hyperpulse mode in the group of nuclear sclerosis grade 1 and 2. CONCLUSIONS: Two different modes of phacoemulsification using Ozil(R) and Hyperpulse mode, and different incision sizes of 2.2 mm and 2.8 mm in Infiniti(R) showed no significant difference in the endothelial cell density or the surgically induced astigmatism up to 2 months after surgery. Phacoemulsification using Ozil(R) mode is considered more efficient in low grade nuclear sclerosis cataract.

Temporal Hemianopsia of Healthy Eye in a Patient with Contralateral Silicone Oil Filled Eye

PURPOSE: To report a case of temporal hemianopsia of a healthy eye occurring in the contralateral silicone oil-filled eye due to migration of silicone oil into the optic chiasm and lateral ventricle. CASE SUMMARY: A 56-year-old man visited our clinic with temporal hemianopsia for 10 days in the left eye. Three months before, the patient had presented with decreased vision and ocular pain in the right eye as well as a headache. The patient underwent vitrectomy at another hospital for the management of retinal detachment occurring in the right eye 8 years earlier. In addition, for recurred retinal detachment, reoperations were performed twice with silicone oil injection. Funduscopy revealed findings such as glaucomatous optic disc and an intraocular pressure of 54 mmHg in the right eye. On visual field examination, the temporal hemianopsia was detected in the left eye. Under the suspicion of cerebral lesions, a magnetic resonance imaging (MRI) examination was performed. On the right side of the optic chiasm and the suprasellar region, materials were present whose signal intensity was identical to silicone oil in the right vitreal cavity. During a follow-up, the migration of silicone oil into the lateral ventricle and the alteration of its location with the positional change were observed. CONCLUSIONS: In a patient who received silicone oil injection following vitrectomy, the silicone oil migrated to the optic chiasm and induced the occurrence of visual field defect in the contralateral eye. The visual field defect improved because of the migration into the lateral ventricle.
