However, its effect on measured global Retinal Nerve Fiber Layer (gRNFL) is not well elucidated. This case evaluates the effect of teprotumumab on gRNFL in a patient with moderate TED. Observations: A 60-year-old female with controlled ocular hypertension and moderate TED received 8 standard IV teprotumumab infusions. Comprehensive ocular evaluations were performed pre-, during-, and post-treatment. Bilateral gRNFL thickness decreased (10 m OD;12 m OS) at 4 months post-treatment start, persisting at 8 months, but recovered at 20 months. Conclusions and Importance: Teprotumumab treatment in patients with TED led to a transient bilateral decrease in gRNFL thickness, which was restored to baseline levels with no adverse events reported. Monitoring gRNFL changes in teprotumumab-treated patients is crucial as gRNFL thinning indicates retinal ganglion cell damage. Teprotumumabs ability to dampen the IGF-IR inflammatory cascade may have reduced retinal inflammation, leading to recovery.展开更多

Design: Retrospective interventional case series. Participants: Thirty-four eyes of 32 patients with idiopathic macular holes that underwent vitrectomy between January 2001 and March 2003 were included in this study. Eyes were divided into 3 groups according to the occurrence of postoperative VF defects and the use of indocyanine green for internal limiting membrane peeling during surgery: 11 eyes with VF defects after indocyanine green-assisted vitrectomy (group 1),9 eyes without VF defects despite the use of indocyanine green (group 2),and 14 eyes without VF defects that underwent vitrectomy without indocyanine green (group 3). Methods: Retinal nerve fiber layer thickness in each of 4 quadrants (superior,inferior,nasal,temporal)was measured with OCT. Main OutcomeMeasure: Retinal nerve fiber layer thickness around the optic disc. Results: The mean RNFL thickness in 3 of 4 quadrants (superior,nasal,inferior) in group 1 was significantly less than that in the corresponding quadrant in groups 2 and 3 (P < 0.01). In the temporal quadrant,there was a significant difference between groups 1 and 3 (P=0.02),but not between groups 1 and 2. The RNFL thickness in group 1 was significantly less in 3 quadrants in operated eyes than in fellow eyes (P< 0.05). Conclusions: The RNFL thickness was reduced in eyes with VF defects after indocyanine green-assisted vitrectomy for macular holes,suggesting that the postoperativeVF defectsmay have been caused by RNFL damage relating to the use of indocyanine green.展开更多
