Article Abstract
Purpose: We report a case of neurotrophic keratopathy (NK) arising after surgery for rhabdomyosarcoma of the jaw successfully treated with Cenegermin eye drops (Oxervate; Dompé Farmaceutici, Milan, Italy) in a 3-year-old boy.
Methods: At the age of 1 year, the boy underwent surgery for rhabdomyosarcoma of the jaw, followed by radiotherapy. Subsequent NK was initially treated with preservative-free artificial tears, topical combination of dexamethasone 0.1% and netilmicin 0.3% (Netildex; Sifi, Catania, Italy), and moxifloxacin 0.5% (Vigamox; Alcon, Fort Worth, TX), followed by 10 cycles of a topical eye biopolymer containing a poly-carboxymethyl glucose sulfate solution (Cacicol; Theà, Clermont-Ferrand, France) and 4 amniotic membrane transplantations. Keratopathy was recalcitrant to therapy and tissue transplant. Therapy was switched to Cenegermin eye drops 6 times daily for 8 weeks.
Results: Complete healing of the corneal epithelium was achieved at 3 weeks into treatment.
Conclusions: Cenegermin was effective in restoring corneal integrity in this pediatric patient with NK.
Purpose: Neurotrophic keratopathy is part of the leprosy sequelae and causes progressive deterioration of visual acuity. Although leprosy is bacteriologically curable, there is currently no efficient treatment. Eye drops containing tetrapeptides, phenylalanine-glycine-leucine-methionine-amide (FGLM-NH) and serine-serine-serine-arginine (SSSR), derived from substance P and insulin-like growth factor 1, are clinically efficacious in the treatment of corneal epithelial disorders caused by neurotrophic keratopathy.
Autologous blood therapy has emerged as a promising modality in managing ocular surface disorders. This review provides a comprehensive overview of the current literature regarding the use of autologous blood in ocular surface disorders, encompassing its physiological basis, clinical applications, techniques, challenges, and future perspectives. The ocular surface, comprising the cornea, conjunctiva, and tear film, plays a critical role in maintaining visual function, and its disruption can lead to various pathological conditions.

The integrity of corneal nerves is critical for ocular surface health, and damages can lead to Neurotrophic Keratopathy (NK). Despite the regenerative abilities of the peripheral nerve system (PNS), corneal nerve regeneration is often incomplete, and the underlying mechanisms are poorly understood. This study aims to identify potential factors that can enhance corneal nerve regeneration for NK treatment, with a focus on Lysophosphatidic acid (LPA).
Purpose: To report the clinical outcomes achieved in refractory cases of neurotrophic keratopathy (NK) through the utilization of insulin eye drops alone or in conjunction with a drug-depository contact lens (DDCL).
Observations: This multicentric prospective open-label uncontrolled case series included consecutive patients with NK refractory to conventional treatment. Insulin eye drops (1 unit/mL) were prescribed 4 times/day in all cases, and a Therapeutic Hyper-CL™ soft contact lens (EyeYon Medical, Ness Ziona, Israel), designed to act as a drug reservoir, was applied in selected patients.
Purpose: To report a rare case of conjunctival neuroma after a successful corneal neurotization surgery.
Methods: The clinical file and histopathology slides of this patient who underwent surgical corneal neurotization for a neurotrophic keratopathy in the right eye were reviewed.
Results: A 70-year-old man with a history of severe herpetic (varicella zoster) neurotrophic keratopathy and keratouveitis in the right eye developed a corneal perforation, which required tectonic keratoplasty (May 2020).
