RESUMEN
Purpose: To find out the mean rate of progression (MROP) of visual fields (VF) in patients with primary open?angle glaucoma (POAG) and ocular hypertension (OHT) using FORUM® Glaucoma Workplace. Methods: Two hundred and one eyes of 105 patients were included in this prospective cohort study. Patients with POAG and OHT were recruited, and VF analysis with 24?2 and or 10?2 was done using SITA standard strategy in Zeiss Humphrey Visual Field Analyzer (HFA). All the previous VFs were identified from FORUM software, and the baseline indices were recorded from the first reliable VF analysis. The present VF analysis was compared to the previous one using FORUM software, and the rate of progression (ROP) in VF was obtained by Guided Progression Analysis. Results: MROP of VF in the POAG group was ? 0.085 dB/ year, ranging from ?2.8 to 2.8 dB/year with a standard deviation (SD) of 0.69. In the OHT group, the MROP of VF was ?0.003 dB/year, ranging from ? 0.8 to 0.5 dB/year with an SD of 0.27. The MROP of VF in medically treated eyes with POAG was ?0.14 dB/year with an SD of 0.61 and in surgically treated eyes was ?0.02 dB/year with an SD of 0.78. The overall baseline mean VF index (VFI) was 83.19% and the final mean VFI was 79.80%. There was a statistically significant decrease in the mean VFI value from baseline to the final visit (P?value 0.0005). Conclusion: The mean ROP of VF in the POAG group was ?0.085 dB/year and in the OHT group was ? 0.003 dB/year
RESUMEN
Purpose: The purpose of this study was to evaluate trainee performance across six modules of a virtual reality (VR) simulator. Methods: A retrospective observational study was conducted on 10 manual small-incision cataract surgery (MSICS) trainees who practiced cataract surgery on an MSICS VR simulator for one month. They were assessed in six major steps which included scleral groove, tunnel dissection, keratome entry, capsulorhexis, nucleus delivery, and intraocular lens (IOL) insertion under a trainer抯 supervision. The information included in their score metrics was collected, and their overall performance was evaluated. Results: Thirty attempts were evaluated for scleral groove, tunnel dissection, and capsulorhexis and 15 attempts for keratome entry. Candidates had varied results in the dimensional aspects and their rates of complications with a mean satisfactory score of 3.1 � 4.17, 6.8 � 5.75, 5.8 � 7.74, and 1.8 � 2.57, respectively. Nucleus delivery (n = 5) had more of iris pull and IOL insertion (n = 5) had more of lost IOL as complications but both had a higher satisfactory outcome. Conclusion: A VR simulator is a useful tool for training surgeons before their entry into live surgery. It is an effective method for evaluating objectively the structural characteristics of each phase in MSICS and their associated complications, helping them anticipate it earlier during live surgery by giving them a near real world experience.
