Evaluation of macular photoreceptor layer with optical coherence tomography and correlation of visual acuity loss in patients with central serous chorioretinopathy.
A prospective observational study was carried out on 40 eyes of 40 patients (35 males and 5 females), age ranging from 26 to 51 years to evaluate the changes in macular photoreceptor layer using optical coherence tomography (OCT) in patients with central serous chorioretinopathy (CSC) and correlate the loss of visual acuity. Fellow normal eye was taken as control.
The CSC with early presentation (34) had attained visual acuity of 6/9 to 6/6 at follow up at three months with preserved profile of outer photo receptor layer. Visual acuity was strongly correlated with profile of OPL (p value=0.001). Complete visual acuity recovery was seen in 95% of cases with a preserved even OPL and 60% cases with a preserved granulated OPL. In second group of six patients where TTT laser was done the granularity of OPL decreased on subsequent follow ups. However, the thickness of macula was unaltered (p value = 0.69). At the onset of the disease for drop of visual acuity by one line, there was approx. 70 micron increase in macular thickness which was very significant, (p value = 0.043). In one patient, the OPL was atrophic at one year follow up and the patient had significant loss of vision.
It was concluded that the preserved photoreceptor layer is associated with a higher and better corrected visual acuity compared with granulated photoreceptor layer. Beneficial role of TTT laser photocoagulation was established in the study. Final outcome on thickness of macula after laser was largely unaltered.
