Randomized Controlled Trial
Subconjunctival lidocaine before laser treatment: a randomized trial.
The aim of the study was to determine whether subconjunctival anesthesia is effective at reducing pain associated with laser retinopexy. ⋯ Subconjunctival 2% lidocaine significantly reduces the incidence of pain in patients who receive PRP or PLR.

Comparative Study
High-resolution imaging of resolved central serous chorioretinopathy using adaptive optics scanning laser ophthalmoscopy.
To compare pathologic changes in photoreceptors in eyes with resolved central serous chorioretinopathy (CSC) seen on high-resolution images obtained by adaptive optics scanning laser ophthalmoscopy (AO SLO) with visual acuity (VA) and findings on spectral-domain optical coherence tomography (SD OCT). ⋯ Adaptive optics SLO images showed abnormal cone mosaic patterns and reduced cone densities in eyes with resolved CSC, and these abnormalities were associated with VA loss, suggesting that AO SLO is a useful means to detect and measure cone abnormalities associated with VA loss in these eyes.
