Purpose: To analyze retinal tears and to compare the clinical outcomes between retinal tear and rhegmatogenous retinal detachment (RRD) as the cause of dense non-diabetic vitreous hemorrhage in patients who underwent vitreoretinal surgery. Methods: In a retrospective case series, the medical records of patients who presented dense non-diabetic vitreous hemorrhage and who underwent vitreoretinal surgery between January 2005 and June 2009 were reviewed. Among the 134 patients, 27 patients had dense vitreous hemorrhage caused by retinal tears. The first group had retinal tears only and the second group had accompanying RRD. A comparison of clinical features and postoperative prognoses between the two groups was performed. Results: Among the 27 eyes with non-traumatic retinal tear and RRD, 18 were categorized into the retinal tear group and 9 to the RRD group. The demographic findings between the two studied groups exhibited no significant differences except for time between onset of symptoms and diagnosis. However, the time to diagnosis was significantly delayed in the group with RRD (22.67 ± 37.47 days) compared to the retinal tear group (5.00 ± 3.41 days) (p = 0.035). The amount of visual improvement was also greater in the retinal tear group than the RRD group (p = 0.002). Conclusions: Retinal tears are a major cause of non-diabetic vitreous hemorrhage. Vitreous hemorrhage caused by retinal detachment may result in delayed diagnosis and poor visual recovery. Therefore, early examinations in suspicion of RRD and appropriate treatments are needed in non-diabetic vitreous hemorrhage. J Korean Ophthalmol Soc 2011;52(4):448-453

Purpose: To investigate the visual recovery and complications of vitrectomy in Terson`s syndrome. Methods: A retrospective study was carried out on 11 eyes in 9 patients who had undergone pars plana vitrectomy for Terson`s syndrome from October 2004 to June 2006. The factors assessed were age, gender, presence of hypertension, type of intracranial hemorrhage, preoperative and final visual acuity, time interval from intracranial hemorrhage (ICH) to vitrectomy, and any intraoperative and postoperative complications. Results: The average age of the subjects and the Interval from ICH to vitrectomy were 43.0±11.0 years and 3.25±3.48 months respectively. Binocular involvement was found in two of the nine patients, and fundus findings were severe vitreous opacity in all cases, while sub-ILM hemorrhage at the posterior pole was seen in five eyes. Intraoperative retinal break was recorded at the 10 o`clock sclerotomy site in five eyes, and four of these five eyes were associated with sub-ILM hemorrhage. One patient underwent a scleral buckling operation four months postoperatively due to rhegmatogenous retinal detachment associated with a retinal tear at the 2 o`clock sclerotomy site. Visual acuity improved in all cases postoperatively, and the final visual acuity was over 0.6 in seven eyes. Conclusions: We can expect from early surgery a relatively good prognosis of visual acuity and prevention of complications. Due to the possibility of retinal breaks at the sclerotomy sites, we should keep in mind that cautious handling of intraocular instrument and complete removal of vitreous base may be necessary.

Purpose: To evaluate the concentrations of commercially available ofloxacin 0.3%, levofloxacin 0.5%, and ciprofloxacin 0.3% topical ophthalmic solutions in human aqueous humor. Methods: Patients scheduled to undergo phacoemulsification and posterior chamber lens insertion for treatment of cataract were enrolled in this prospective study. After informed consent was obtained, patients were randomized to receive 1 drop of ofloxacin 0.3%, levofloxacin 0.5%, or ciprofloxacin 0.3% topical ophthalmic solution 5 times at 1-hour intervals from 6pm one day before surgery and 3 further times at 5-min intervals immediately before surgery. After aspirating approximately 0.1 mL of aqueous fluid by paracentesis, surgery was commenced. We recorded the interval between the last drop and paracentesis. Specimens were stored at -70℃ until assayed by high-performance liquid chromatography. Results: Thirty-four patients were enrolled. 14 male and 19 patients female. The mean age was 59.4 years. The mean concentrations of levofloxacin, ofloxacin and ciprofloxacin in aqueous humor were 577.8 ng/ml, 279.6 ng/ml and 53.0 ng/ml, respectively. The differences of concentration among the three groups were statistically significant. Conclusions: The concentration of levofloxacin 0.5% solution was highest, followed in order by ofloxacin 0.3% and ciprofloxacin 0.3%.
유리체망막수술시 테논낭하마취의 용량에 따른 안압 및 마취효과의 비교

Purpose: To compare the effects of different volumes of sub-Tenon`s anesthetic on intraocular pressure (IOP) and to evaluate the treatment efficacy of vitreoretinal surgery. Methods: A prospective, clinical trial was conducted on patients undergoing sub-Tenon`s anesthesea for vitreoretinal surgery. Patients were randomized to receive either 3 mL, 5 mL or 7 mL of anesthetic solution. IOPs were measured immediately prior to, immediately after, and at 2, 5 and 10 min after the injection. Pain scores were assigned using a numerical visual analogue scale immediately following surgery and again on postoperative day one. Results: A total of 108 patients (119 eyes) were studied, including 35 eyes in the 3 mL group, 48 eyes in the 5 mL group, and 36 eyes in the 7 mL group. There was significant elevation in mean IOP following injection in all groups and a trend toward a larger increase in the group receiving the larger volume (p<0.01). Mean IOPs were elevated immediately after the injections and reduced at all subsequent time intervals. But reduction to the pre-injection level was only achieved in the 3 mL group. There was no significant difference in patient-reported pain scores among the groups when assessed immediately after surgery or on postoperative day one. The incidence of chemosis and high IOP elevation (40 mmHg ≤) was more frequent in the 7 mL group than the other groups (p<0.05). Conclusions: Sub-Tenon`s anesthesia is effective in vitreoretinal surgery. It would appear that a 3-5 mL volume of anesthetic is safe even when complications are considered.

Purpose: To compare the visual field and retinal nerve fiber layer of scleral buckling (SB) and primary pars plana vitrectomy (PPV) for treatment of simple rhegmatogenous retinal detachment (RRD). Methods: We studied 20 eyes with RRD that were underwent successful surgical reattachment. Visual field test and retinal nerve fiber layer (RNFL) thickness measurements were performed in patients, and outcomes were compared not only between the operated eye and fellow eye, but also between SB and PPV 3 months postoperatively. Results: After the operation, PSD and MD were higher in the operated eye than in the fellow eye (p = 0.002, p < 0.001, respectively). RNFL thickness was lower in the operated eye than in the fellow eye (p < 0.001). No significant differences in BCVA were detected between SB and PPV. However, the respective differences between the operated eye and fellow eye regarding pattern standard deviation (4.0 ± 4.0, 0.7 ± 1.5), mean deviation (6.5 ± 4.6, 1.9 ± 1.9), and RNFL (8.2 ± 10.3 μm, 1.8 ± 2.7 μm) were significantly higher in PPV than in SB. Conclusions: Both visual field defect and retinal nerve fiber damage are significantly larger in PPV than in SB. J Korean Ophthalmol Soc 2012;53(9):1285-1290
