Characterization of macular lesions in punctate inner choroidopathy with spectral domain optical coherence tomography.

ABSTRACT:

Purpose

Punctate inner choroidopathy (PIC) is an ocular inflammatory disease. Spectral domain optical coherence tomography (SD-OCT) allows detailed visualization of retinal and choroidal structures. We aimed to describe the retinal changes on SD-OCT associated with PIC lesions localized in the macula.

Methods

Retrospective case series: PIC lesions not associated with choroidal neovascularization (CNV) and captured by macular SD-OCT scans were identified and characterized.

Results

Twenty-seven PIC lesions from seven patients (eight eyes) were identified and classified into four categories according to disease activity and temporal changes. Among clinically inactive patients, two main patterns were noted on OCT: (1) retinal pigment epithelium (RPE) elevation with sub-RPE hyper-reflective signals and (2) localized disruption of outer retinal layers with choroid and Bruch's membrane (BM) generally spared. Clinically active patients demonstrated lesions with intact BM with RPE elevation that fluctuated with disease activity and sub-RPE hyper-reflective signals. Photoreceptor-associated bands on SD-OCT (PRs) were not visible during active disease, but returned to normal visibility when lesions were clinically stable. Seven lesions in patients without clinically detected activity demonstrated alteration of RPE elevation.

Conclusion

SD-OCT can provide detailed structural characteristics of PIC lesions. RPE elevation is noted in many lesions while BM and choroid are spared. Photoreceptor-associated bands on SD-OCT appear compressed during clinically active stages and are visible during stabilization. OCT may provide information on activity not detected clinically.

Project description:PurposeDescribe qualitative spectral-domain optical coherence tomography (SD-OCT) characteristics of eyes classified as intermediate age-related macular degeneration (nonadvanced AMD) from Age-Related Eye Disease Study 2 (AREDS2) color fundus photography (CFP) grading.DesignProspective cross-sectional study.ParticipantsWe included 345 AREDS2 participants from 4 study centers and 122 control participants who lack CFP features of intermediate AMD.MethodsBoth eyes were imaged with SD-OCT and CFP. The SD-OCT macular volume scans were graded for the presence of 5 retinal, 5 subretinal, and 4 drusen characteristics. In all, 314 AREDS2 participants with ?1 category-3 AMD eye and all controls each had 1 eye entered into SD-OCT analysis, with 63 eyes regraded to test reproducibility.Main outcome measuresWe assessed SD-OCT characteristics at baseline.ResultsIn 98% of AMD eyes, SD-OCT grading of all characteristics was successful, detecting drusen in 99.7%, retinal pigment epithelium (RPE) atrophy/absence in 22.9%, subfoveal geographic atrophy in 2.5%, and fluid in or under the retina in 25.5%. Twenty-eight percent of AMD eyes had characteristics of possible advanced AMD on SD-OCT. Two percent of control eyes had drusen on SD-OCT. Vision loss was not correlated with foveal drusen alone, but with foveal drusen that were associated with other foveal pathology and with overlying focal hyperreflectivity. Focal hyperreflectivity over drusen, drusen cores, and hyper- or hyporeflectivity of drusen were also associated with RPE atrophy.ConclusionsMacular pathologies in AMD can be qualitatively and reproducibly evaluated with SD-OCT, identifying pathologic features that are associated with vision loss, RPE atrophy, and even possibly the presence of advanced AMD not apparent on CFP. Qualitative and detailed SD-OCT analysis can contribute to the anatomic characterization of AMD in clinical studies of vision loss and disease progression.Financial disclosure(s)Proprietary or commercial disclosure may be found after the references.

Project description:ObjectiveTo evaluate subclinical macular findings in premature patients at risk of retinopathy of prematurity (ROP) with the use of handheld spectral-domain optical coherence tomography (SD-OCT).DesignProspective, observational case series.ParticipantsForty-nine prematurely born neonates.MethodsForty-nine infants were imaged using a handheld SD-OCT. Images were acquired in nonsedated infants in the neonatal intensive care unit (NICU). Some patients were followed and reimaged over the course of several weeks. A total of 300 total images were acquired and evaluated for cystoid macular edema (CME) and persistence of inner retinal layers.Main outcome measuresIn vivo determination of foveal retinal lamination, image analysis, and clinical observation.ResultsA total of 241 (80%) of the images from 46 patients were usable (defined as having scans passing through the fovea with clearly identifiable retinal layers). Persistence of 1 or more inner retinal layers was seen in 43 of the patients with usable images (93%). Of the patients with at least 1 persistent layer, 17, 4, 8, 12, and 1, had a maximum ROP stage of 0, 1, 2, 3, and 4A, respectively. Cystoid macular edema was seen in 25 of the 46 patients (54%) during 1 or more imaging sessions. Cystoid macular edema was present in 9, 1, 5, 9, and 1 patient with maximum ROP stage of 0, 1, 2, 3, and 4A, respectively.ConclusionsOur data suggest there is persistence of inner retinal layers in premature infants regardless of maximal ROP stage. Subclinical CME is seen in premature infants; however, CME does not appear to be correlated with ROP stage. This suggests that there may be other causes for the CME seen in this patient population. Hand-held SD-OCT imaging is a viable technique for evaluating subclinical macular findings in premature infants, although larger datasets are needed from multiple centers to further evaluate the generalizability of these findings.Financial disclosure(s)The author(s) have no proprietary or commercial interest in any materials discussed in this article.
