Hast., İstanbul, Prof. Dr. Purpose: Central serous chorioretinopathy (CSCR) is a local neurosensorial retinal detachment due to liquid leakage at the level of retinal pigment epithelium (RPE). In this study our aim is to determine the reliability of preferential hyperacuity perimeter (PHP) for diagnosis and follow up of CSCR.
Materials and Methods: Study is performed in T.C. Istanbul Bilim University Florence Nighthingale hospital ophthalmology department between dates of November 2007, February 2008. Twelve patients, 7 male and 5 female patients were included in to our study. In all 12 patients, routine ophthalmologic examination, fluorescein angiography (FA), PHP and optical coherence tomography (OCT) were performed both at the beginning ant and also at the end of 3.4 months average (min. 3 months- maks. 4 months) follow-up period.
Results: Average age was 44.7+/-7.2 (range; 32-68). Average best corrected visual acuity of cases was 20/100 (range 20/40-20/200) at the beginning. Average macula thickness of cases was 585+/-292 micron which is measured with OCT at the beginning. While at 5 patients of 12 patients had local scotomas, 7 patients had not any scotomas at preferential hyperacuity (PHP) test. (p>0.05) Twelve patients were followed for average 3.4 months, in two cases improvement were not seen. Average macula thickness of cases after follow-up period was 585+/-292 micron which is measured with OCT at the beginning. PHP tests were repeated in all patients with serous detachment at OCT, it was seen that except 2 patients with out improvement, all cases PHP results are normal. Average best corrected visual acuity of cases was 20/30 (range 20/100-20/20) at the end of follow-up period.
Conclusion: According to our results to find scotomas in PHP test in 5 patients over 12 patients with CSCR showed the insufficiency of this tool for the diagnosis of CSCR. On the other hand not to find any local scotomas in all patients with improvement showed that this tool can be used for follow-up.
