    Abstract: To analyze vitreoretinal findings, immunoglobulin clonality tests, and interleukin (IL) levels for diagnosing vitreoretinal lymphoma (VRL). Methods: Forty-three patients who underwent diagnostic vitrectomy for suspected VRL were retrospectively reviewed. Of those patients finally diagnosed with VRL and nonlymphoma, ophthalmic evaluation and cytology results, IL-6 and IL-10 levels, and immunoglobulin heavy chain and immunoglobulin kappa light chain clonality assays were compared. Results: Sub-retinal pigment epithelium infiltration and veil-pattern vitreous opacity were specific vitreoretinal findings in patients with VRL. The area under the receiver operating characteristic curve of the IL-10-to-IL-6 ratio and of IL-10 levels was 0.972 and 0.931, respectively. A combined immunoglobulin heavy chain and immunoglobulin kappa light chain assay showed increased sensitivity, whereas the determined specificity of immunoglobulin kappa light chain, at 94.12%, was much higher than the 78.95% of immunoglobulin heavy chain. Patients with VRL with atypically elevated IL-6 levels showed extensive and severe sub-retinal pigment epithelium infiltration. Conclusion: Newly screened immunoglobulin kappa light chain clonality assays may be useful to distinguish VRL from uveitis with high specificity. When sub-retinal pigment epithelium or retinal infiltration is severe and extensive, the IL-10-to-IL-6 ratio may not be typical and should be carefully interpreted.

    Abstract: To investigate the prevalence of pachydrusen, soft drusen, and subretinal drusenoid deposits in eyes with different neovascular age-related macular degeneration (nAMD) subtypes, determine the relationship between each drusen type and the choroidal thickness, and analyze the distinct features of each nAMD subtype according to the drusen type. Methods: Medical records involving 454 eyes from 454 patients with nAMD were retrospectively reviewed. The prevalence of each drusen type and the choroidal thickness and choroidal characteristics were evaluated according to the nAMD subtype. Results: Pachydrusen were prevalent in the typical nAMD (40.4%) and polypoidal choroidal vasculopathy (47.8%) groups and were not detected in the retinal angiomatous proliferation group. No significant drusen were detected in 24.3% of typical nAMD, 43.3% of polypoidal choroidal vasculopathy, and 0% of retinal angiomatous proliferation groups. Regardless of the nAMD subtype, pachydrusen, soft drusen, and subretinal drusenoid deposits were associated with a thick, moderately thick, and thin choroid, respectively. For eyes with typical nAMD, the prevalence of choroidal vascular hyperpermeability and extrafoveal neovascularization was significantly higher in the pachydrusen group than in the other groups. By contrast, the prevalence of Type 2 neovascularization was significantly lower in the pachydrusen group than in the subretinal drusenoid deposit group ( P 〈 0.001 for all). Conclusion: The prevalence of various drusen differed according to the nAMD subtypes, and each drusen type was strongly associated with the choroidal thickness. Typical nAMD showed distinct features according to the accompanying drusen type.

    Abstract: To investigate predictive factors for redislocation in patients with recurrent intraocular lens (IOL) dislocation following secondary scleral-fixated IOL (SFIOL) surgery. Setting: Two tertiary referral hospitals Design: Retrospective case series Methods: Patients undergoing SFIOL surgery were grouped into redislocation and no-redislocation groups. Medical records of consecutive patients who underwent SFIOL surgery between June 2014 and December 2019 at two tertiary referral centers were reviewed. Data regarding patient demographics, treatment factors, anatomical and functional outcomes, and postoperative complications were recorded. Results: We included 237 eyes of 225 patients (169 [75.1%] men). The redislocation group was more likely to have a younger mean age at the initial SFIOL surgery (redislocation vs no-redislocation, 55.4 vs 62.0 years, respectively; P =0.008), have a prior history of a previous suture-break (23 eyes, 52.3% vs 1 eye, 0.5%; P 〈 0.001), and have undergone the initial SFIOL surgery using 〈 1 mm-sized side-port incisions (17 eyes, 38.6% vs 32 eyes, 16.5%; P =0.002) than was the no-redislocation group. Additionally, the redislocation group had a higher occurrence of complications ( P 〈 0.001). Multivariable regression revealed that younger age, left eye involvement, aphakic status prior to the surgery, unremarkable primary IOL dislocation cause, need for ocular hypertension treatment and glaucoma surgery, and no large incision during the initial surgery were significantly (all P 〈 0.05) associated with redislocation. Conclusion: Younger age, left eye involvement, postoperative complications like ocular hypertension and glaucoma, and techniques without large incisions increase the risk of redislocation. Conversely, lower risk factors include unremarkable surgery causes and a history of aphakic conditions.
