PURPOSEnTo investigate the effect of yellow-tinted intraocular lenses (IOLs) on short-wavelength automated perimetry (SWAP).nnnDESIGNnCross-sectional observation study.nnnMETHODSnTwenty-two patients who had implantation of yellow-tinted IOLs (AcrySof SN60AT or SN60WF; Alcon Laboratories) in 1 eye and nontinted IOLs (AcrySof SA60AT) in the other eye were included in the study. Standard automated perimetry (SAP) and SWAP were performed. The results for the mean deviation (MD), pattern standard deviation (PSD), and glaucoma hemifield test results were compared intra-individually.nnnRESULTSnThere was no statistically significant difference between the IOLs on the SAP (MD, PSD; P = .851, P = .388, respectively). However, a significant difference was observed between the IOLs on the SWAP (MD, PSD; P = .033, P = .033, respectively). The glaucoma hemifield test did not show significant differences in the SAP (P = .083). However, the SWAP showed significant differences (P = .003).nnnCONCLUSIONSnThe yellow-tinted IOLs may affect the results of the SWAP; therefore, caution is needed in interpreting the results of the SWAP in eyes with implanted yellow-tinted IOLs.

We investigated the case of a young man with blurred vision in his left eye. His visual acuity was slightly decreased, and ophthalmoscopy disclosed a gray-white lesion in the macula. He had no systemic or ocular history. On the visual field test, the threshold sensitivity was decreased in the corresponding region. Spectral domain optical coherence tomography (OCT) demonstrated a disruption in the photoreceptor inner and outer segment (IS/OS) junction and undulation of the retinal pigment epithelium (RPE) with backscattering. We re-examined the patient after two weeks and after three months without any treatment. Visual acuity and visual field results were gradually normalized, and OCT demonstrated the recovery of continuity in the photoreceptor IS/OS junction, as well as decreased RPE irregularity with minimal backscattering. We used spectral domain OCT instead of time domain OCT (OCT3) so that we could provide better image resolution of the acute retinal pigment epitheliitis (ARPE). Finally, we observed recovery of the functional and anatomical changes in the ARPE patient with a resolution of the condition within three months following the initial examination, using OCT and visual field tests.
