Retinitis Pigmentozalı Hastalarda Makuler OKT.

Purpose: To evaluate macula by optical coherence tomography (OCT) in retinitis pigmentosa patients. Materials and Methods: Central foveal thickness (CFT) was measured by OCT3 with 6 mm horizontal scans passing through fovea. The configuration of the inner segment/ outer segment junction (IS/OS band) in the grey scale OCT images at the fovea was graded between 1 and 3. According to this IS/OS band was not visible in Grade 1, abnormal IS/OS band under fovea in Grade 2, and normal IS/OS band in Grade 3. The correlation of the grade of IS/OS band with age, sex, visual acuity and CFT was evaluated. Results: IS/OS band was in Grade 1 in 19 eyes (40%), in Grade 2 in 13 eyes (28%), and in Grade 3 in 15 eyes (32%). The difference between the grade of IS/OS band and sex and age of patients was statistically insignificant (p>0.05). The visual acuity of eyes in Grade 3 was higher than eyes in Grade1 and 2 (p<0.05). The CFT of eyes in Grade 3 was higher than eyes in Grade1 (p<0.05). Conclusion: The integrity of IS/OS band may be a sign of the preserved foveal functions; and may be an indicator of potential visual functions. [ABSTRACT FROM AUTHOR]
