Short-term, high-dose hydroxychloroquine corneal toxicity.

ABSTRACT: Purpose:To describe the corneal findings and management of a 61-year-old female with vortex keratopathy following short term, high dose hydroxychloroquine used in the setting of a clinical trial for recurrent breast cancer. Observations:The patient was found to have significant corneal vortex keratopathy without retinal pathology within 3 months of 1200 mg daily hydroxychloroquine treatment as an adjuvant medication for cancer therapy. Cessation of the medication led to the resolution of the corneal verticillata within 1 month yet the vision did not return to baseline. Ultimately, remaining irregular astigmatism and ocular surface disease required a scleral contact lens to achieve a BSCVA of 20/25 OU. Conclusions and Importance:Hydroxychloroquine-induced vortex keratopathy is largely considered dose and duration dependent and is uncommon with most standard treatment algorithms. However, with increasing use of high-dose hydroxychloroquine in adjunct cancer therapy, corneal findings are likely to become more frequent. Persistent visual impairment may occur, thus increased understanding of this pathology can aid in counseling patients and guiding treatment recommendations.

Project description:PurposeTo evaluate the early corneal remodeling and its influencing factors after Small incision lenticule extraction (SMILE) for moderate and high myopia.MethodsThis was a retrospective study. Pre- and post-operative (1 week and 1, 3, 6 months) corneal volume (CV), mean keratometry (Km), and corneal thickness (CT) were measured by Scheimpflug tomography. CT at the central, thinnest point, and on concentric circles of 2, 4, and 6 mm diameter was recorded to assess corneal thickness spatial profile (CTSP) and percentage of thickness increase (PTI) in the moderate and high myopia groups, and to explore possible influencing factors.ResultsAfter SMILE, the peripheral CT decreased in the moderate myopia group and central corneal thickness (CCT) increased in the high myopia group at 1 month compared to 1 week (all P < 0.05). The CV, Km and CT were significantly increased at 3 months compared to 1 month (all P < 0.05), but there was no significant change at 6 months compared to 3 months for both groups (all P > 0.05). Patients with high myopia showed greater corneal thickness changes (△CT) and higher PTI than moderate myopia (all P < 0.05). Regression analysis revealed that in addition to refraction, peripheral PTI was negatively correlated with CCT in the moderate myopia group (4 mm: β = -0.023, P = 0.001; 6 mm: β = -0.050, P < 0.001), as well as in the high myopia group (4 mm: β = -0.038, P < 0.001; 6 mm: β = -0.094, P < 0.001). Moreover, peripheral PTI in the moderate myopia group was negatively correlated with age (4 mm: β = -0.071, P = 0.003; 6 mm: β = -0.162, P < 0.001).ConclusionsAfter SMILE, the CV, Km, and CTSP showed dynamic changes in the early stage, which stabilized after 3 months. Compared to the moderate myopia group, the high myopia group experienced slower corneal stabilization. The change in PTI at 6 months after SMILE may be related to higher preoperative refraction, thinner CCT and younger age.
