Intraocular Metastasis of Large T-cell Lymphoma Transformed from Mycosis Fungoides

PURPOSE

To describe a rare case of intraocular lymphoma that metastasized from cutaneous mycosis fungoides and transformed to large cell T cell lymphoma resulting in vitreoretinal pathology.

METHODS

Retrospective case report.

RESULTS

A 57-year-old male presented with 3 months of blurred vision in the right eye. He reported only a medical history of psoriasis. Examination revealed keratic precipitates and dense vitritis in the right eye. He was taken for a diagnostic vitrectomy. Histopathology showed that atypical lymphoid cells and flow cytometry were consistent with transformed large cell T-cell lymphoma. During follow-up, pre- and inner retinal lesions were noted throughout the posterior pole. Histopathology of the psoriatic lesions was consistent with mycosis fungoides. He was initiated on systemic and intravitreal methotrexate with improvement in vision.

CONCLUSIONS

Ocular involvement in metastatic transformed T-cell lymphoma is extremely rare but can be present with vitritis and retinal deposits. Our patient responded well to intravitreal methotrexate therapy.

Follow-up Rates After Teleretinal Screening for Diabetic Retinopathy: Assessing Patient Barriers to Care

Purpose: To study patient follow-up after they engage in a teleretinal screening program and to understand potential barriers to care. Methods: This was a retrospective analysis and a prospective study of telephone-based patient interviews of outpatients screened for diabetic retinopathy (DR) through a teleretinal referral system. Results: Of 2761 patients screened through a teleretinal referral program, 123 (4.5%) had moderate nonproliferative DR (NPDR), 83 (3.0%) had severe NPDR, and 31 (1.1%) had proliferative DR. Of the 114 patients with severe NPDR or worse, 67 (58.8%) saw an ophthalmologist within 3 months of referral. Eighty percent of interviewed patients reported they were not aware of the need for follow-up eye appointments. Conclusions: Of patients with severe retinopathy or worse, 58.8% presented for in-person evaluation and treatment within 3 months of screening. Although this result was negatively affected by factors related to the COVID-19 pandemic, key elements of patient education and improved referral strategies to facilitate in-person treatment are essential to improving follow-up after patients engage in telescreening.

ASSESSING THE ABILITY OF PREOPERATIVE QUANTITATIVE SPECTRAL-DOMAIN OPTICAL COHERENCE TOMOGRAPHY CHARACTERISTICS TO PREDICT VISUAL OUTCOME IN IDIOPATHIC MACULAR HOLE SURGERY

PURPOSE

To determine which spectral domain optical coherence tomography biomarkers of idiopathic macular hole (MH) correlate with the postoperative best-corrected visual acuity (BCVA) in anatomically closed MH.

METHODS

Retrospective analysis of spectral domain optical coherence tomography scans of 44 patients presenting with MH followed for a mean of 17 months. Widths of MH aperture, base, and ellipsoid zone disruption were calculated from presenting foveal spectral domain optical coherence tomography B-scans. Macular hole base area and ellipsoid zone disruption area were calculated through the custom in-house software.

RESULTS

Poorer postoperative BCVA correlated with increased preoperative choroidal hypertransmission (r = 0.503, P = 0.0005), minimum diameter (r = 0.491, P = 0.0007), and base diameter (r = 0.319, P = 0.0348), but not with preoperative ellipsoid zone width (r = 0.199, P = 0.2001). Applying en-face analysis, the BCVA correlated weakly with preoperative ellipsoid zone loss area (r = 0.380, P = 0.013), but not with preoperative MH base area (r = 0.253, P = 0.1058).

CONCLUSION

Increased MH minimum diameter, base diameter, base area, and choroidal hypertransmission are correlated with a poorer postoperative BCVA. Ellipsoid zone loss measurements were not consistently correlated with a BCVA. Choroidal hypertransmission width may be an easy-to-visualize predictive imaging biomarker in MH surgery.

Long-Term Multimodal Imaging of Solar Retinopathy

This is a rare, multimodal imaging report spanning a decade of monitoring in a patient with chronic solar retinopathy showing the natural course of the disease. Spectral-domain optical coherence tomography (SD-OCT) showed mild widening of subfoveal loss of ellipsoid and interdigitation zones bilaterally, progressive retinal pigment epithelial thinning in the right eye, and hyperplasia in the left eye. Structural en face OCT showed subfoveal tissue loss bilaterally. There was no leakage on fluorescein angiography and OCT angiography (OCTA), and dense B-scan OCTA images were unremarkable. Microperimetry revealed bilateral decreased central sensitivity and eccentric fixation in the left eye. Vision remained stable throughout. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:388-392.].
