RESUMO
Objectives: To compare the global indices obtained by Swedish Interactive Threshold Algorithm [SITA]-Standard strategy with those obtained by SITA-Fast strategy using Humphrey Visual Field Analyzer, in patients of glaucoma
Study Design: Cross Sectional/Validative Study
Place And Duration: Armed Forces Institute of Opthalmology, between March and September 2010
Methodology: SITA Standard and SITA Fast visual field analysis of 184 patients were carried out on Humphrey Visual Field Analyzer [HFA-II] using white on white perimetry with 30-2 program on consecutive patients that fit the inclusion criteria, presenting to Armed Forces Institute of Ophthalmology [Rwp] between March 2010 and September 2010. Value of Pattern Standard Deviation [PSD], Mean Deviation [MD] and time taken to complete the examination were noted.. A p-value of <0.05 was considered significant
Results: The Mean Deviation [MD] as calculated by the HFA-II, using the SITA Standard algorithm was -14.03 +/- 6.31 dB, MD calculated by SITA Fast algorithm was -13.8 +/- 6.2 dB, with no significant difference between the two, p>0.05 The mean PSD as calculated by the HFA-II, using the SITA Standard algorithm was 7.7 +/- 4.4 dB, PSD using the SITA Fast algorithm was 7.5 +/- 4.2 dB, with no significant difference between them, p < 0.05. It took 6:34 +/-2.1 minutes to complete the examination with the Fast strategy and 9.3+/-2.6 minutes with the Standard Strategy. The results were significant
Conclusion: SITA Fast strategy takes significantly less time to complete an examination with the same reliability as SITA Standard strategy
RESUMO
Valsalva retinopathy is a rare condition characterized by preretinal haemorrhage in patients with H/O increased intrathoracic pressure caused by forceful exhalation against a closed glottis. We are presenting a case of a young male adult who developed bilateral valsalva retinopathy following strenuous exercise
Examination of his fundus revealed a round, circumscribed bright-red mound of blood over both maculae
The extent of the lesion in left eye was lesser than the right eye. He was managed conservatively and showed remarkable visual recovery with return of vision to normal in both eyes after 12 weeks
