Purpose: To report a case of an intracorneal hematoma after canaloplasty.
Methods: Interventional case report of a surgical method used to resolve an intracorneal hematoma complication after canaloplasty.
Results: A 45-year-old man with uncontrolled pigmentary open-angle glaucoma underwent canaloplasty for glaucoma in the left eye. The patient previously underwent radial keratotomy for myopia in the same eye in 1997. Visual acuity was 20/20 without corrective lenses; intraocular pressure was 25 mm Hg with maximal medical therapy. During the surgical procedure, the canaloplasty microcatheter encountered an obstacle at the 6-o'clock position. During catheterization, a high-weight viscoelastic substance is normally injected in the canal. This probably caused a limited detachment of the Descemet membrane. On the day after surgery, slit-lamp biomicroscopy showed a large intracorneal hematoma that threatened the visual axis. A partial-thickness paracentesis was then performed on day 2 to remove the hematoma.
Conclusions: Intracorneal hematoma is a rare complication of canaloplasty for glaucoma. The blood can be removed without interrupting the Descemet membrane by partial-thickness paracentesis.

Clinical characteristics, treatment and outcome of clindamycin induced acute generalized exanthematous pustulosis.
Arch Dermatol Res
August 2024
College of Pharmacy, Changsha Medical University, Changsha, 410219, Hunan, China.
Article Synopsis
- Acute generalized exanthematous pustulosis (AGEP) is a serious but rare reaction to clindamycin, characterized by pustular lesions, fever, and itching, primarily seen in females around the median age of 57.
- In a study of 35 patients, AGEP typically appeared 2 days after starting clindamycin, with lesions mostly affecting the extremities and trunk, along with significant neutrophil elevation.
- The condition is self-limiting, and patients experienced recovery after stopping the drug and receiving supportive care, with a typical recovery time of 9 days; thus, awareness and prompt action by clinicians are crucial.
Corneal Toxicity in Patients Treated by BELANTAMAB MAFODOTIN: How to Improve and Facilitate Patients Follow-Up Using Refractive Shift?

Evergreen Vet Research & Publication, Duvall, Washington, USA.
Objectives: To describe the traction suture fixation technique for severely displaced lenses (≥180°) using a capsular tension ring (CTR) fragment during cataract surgery in dogs, and to retrospectively investigate its clinical outcomes.
Animals Studied: Eight dogs (nine eyes).
Procedures: The medical records of dogs with severe lens displacement (≥180°) due to cataracts that underwent traction suture fixation during cataract surgery using a CTR fragment at the Grand Animal Hospital (Hyogo, Japan) between November 2019 and September 2022 were retrospectively reviewed.
Stromal peeling for deep anterior lamellar keratoplasty in a post-penetrating keratoplasty eye with hematocornea.
Am J Ophthalmol Case Rep

University of Ferrara, Department of Translational Medicine, Ferrara, Italy.
Purpose: To present a case of hematocornea occurring in a post-penetrating keratoplasty (PK) eye and to report the outcomes of deep anterior lamellar keratoplasty (DALK) performed by simple stromal peeling.
Observations: A 45-year-old female presented with hematocornea in the left eye that previously underwent PK 26 months prior for keratoconus. Clinical examination revealed a dense reddish-brown opacity within the PK graft which was associated with deep corneal neovascularization.
