Effect of keratorefractive surgery on choroidal thickness in anisometropic amblyopia.

PURPOSE: To evaluate postoperative change in choroidal thickness (CT) in patients with anisometropic amblyopia undergoing keratorefractive surgery. METHODS: Anisometropic amblyopic patients and nonamblyopic patients who underwent keratorefractive surgery were included in the study. The eyes were divided into three groups. Group 1 consisted of eyes with anisometropic amblyopia, group 2 were the nonamblyopic fellow eyes, and group 3 (control group) were nonamblyopic eyes which had undergone keratorefractive surgery. At the third postoperative month, the CT of these eyes were measured by Enhanced Depth Imaging OCT (EDI-OCT). The choroidal thickness (CT) was measured in the subfoveal area and at 500 micron intervals nasally and temporally. RESULTS: Twenty-three anisometropic amblyopia patients with amblyopic and fellow eyes and 23 control eyes were enrolled. The mean subfoveal choroidal thickness (CT) was 387.3±168.8µm in group 1, 412.2±88.8µm in group 2 and 337.3±99µm in group 3 (P: 0.019). Group 1 and group 2 showed higher choroidal thickness (CT) in the nasal and temporal quadrants than group 3 (P: 0.03, P: 0.04). At the third postoperative month, central foveal choroidal thickness was 356.6±115.5µm in group 1, 375.1±112.5µm in group 2 and 284.4±98.9µm in group 3 (P: 0.071). Choroidal thickness (CT) in the nasal and temporal quadrants at the third postoperative month was also similar (P: 0.210, P: 0.103). CONCLUSIONS: The macular choroid is thicker in amblyopic eyes and non-amblyopic fellow eyes than in the nonamblyopic controls. Improved fixation after refractive surgery may normalize CT.

Validity of ocular trauma score in open globe injury patients from Turkey.

OBJECTIVE: To determine the efficacy of ocular trauma score (OTS) in determining the prognosis in patients with open globe injury who admitted to our clinic. MATERIALS AND METHODS: Data of patients with open globe injury who were admitted to our clinic between 2014 and 2016 were retrospectively analyzed. The OTS raw score of each patient was determined and translated into OTS categories according to OTS study. Prognostic results of OTS study and current study was compared with chi square analysis. RESULTS: In our study, 101 eyes of 101 patients were examined. The mean age of the patients was 27.08±15.36 years. The mean follow-up period was 12.84±9.04 months. In total, 86 of the cases were male (85.1%). In our study, the mean initial visual acuity of the patients was 0.10±0.23. In 64.3% of the cases, IVA was at hand movement level or lower. IVA was found to be≥20/40 in 10.9%. The mean FVA was 0.38±0.37. In total, 41.6% of the cases had a FVA≥20/40. In 28.7% of these cases, FVA was at hand movement level or lower. While no significant difference was found in patients with OTS3, OTS 4 and OTS 5 (P>0.05), prognosis of patients with OTS 1 and OTS 2 was better than OTS study (P<0.001) CONCLUSION: Although OTS can be effective and safe data in terms of prognosis, it can be improved with more comprehensive studies.

Comparative evaluation of re-use or replacement of dislocated 3-piece intraocular lenses with a scleral fixation technique.

PURPOSE: To compare the surgical outcomes of refixation and exchange in cases with 3-piece intraocular lens (IOL) dislocation which underwent scleral fixation. MATERIALS AND METHOD: Between 2014 and 2017, 65 eyes of 65 patients diagnosed with 3-piece IOL dislocation were treated with scleral fixation, and their records were retrospectively evaluated. Our patients were divided into two groups based on the treatment - exchange (Group 1) and refixation (Group 2). Dislocated IOL removal and new IOL insertion was performed with scleral fixation in group 1, and in group 2, scleral fixation of the dislocated intraocular lens performed without removal. Visual results, intraoperative and postoperative complications and lens induced astigmatism secondary to scleral fixation were compared between two groups. RESULTS: Patients in both groups were followed for an average of 13.62±3.4 months. Twenty-six patients were in group 1 and 39 patients were in group 2. All of the scleral fixation lenses were 3-pieced. Increased visual acuity was observed in both groups, and no difference was detected between the two groups (P˂0.01). Intraocular lens-induced astigmatism was similar in both groups (P=0.68). Intraocular hemorrhage as an intraoperative complication was seen in two patients in group 1 and one patient in group 2. Redislocation in three patients in group 2 and cystoid macular edema in one patient in each groups were observed. CONCLUSION: Refixation and exchange are both effective in IOL dislocation, and no significant difference between the methods was detected in terms of the results obtained.
