INTRODUCTION: Neurotrophic keratitis, a degenerative corneal disease caused by trigeminal nerve impairment, has many etiologies and remains very difficult to treat. METHODS: Case report of a 23-year-old male with a right corneal ulcer that failed to improve despite broad-spectrum antimicrobials. RESULTS: Prior diagnosis of disseminated lymphangiomatosis with a lesion in the right petrous apex effacing Meckel's (trigeminal) cave in conjunction with a history of nonhealing corneal abrasions suggested a neurotrophic etiology. Drawstring temporary tarsorrhaphy, in addition to antibiotics and autologous serum, lead to successful clearing of the infection and resolution of the corneal ulcer. Visual acuity improved from light perception (LP) at the peak of infection to 20/40 six weeks after treatment. CONCLUSIONS: To our knowledge, we report the first case of neurotrophic keratitis in a patient with disseminated lymphangiomatosis that caused a mass effect in Meckel's (trigeminal) cave leading to compression of the trigeminal nerve. The antibiotic-resistant corneal ulcer was successfully treated with drawstring tarsorrhaphy, confirming the utility of this therapeutic measure in treating neurotrophic keratitis

The antibiotic-resistant corneal ulcer was successfully treated with drawstring tarsorrhaphy, confirming the utility of this therapeutic measure in treating neurotrophic keratitis.Keywords: neurotrophic keratitis, corneal abrasion, drawstring tarsorrhaphy, disseminated lymphangiomatosisIntroductionNeurotrophic keratitis is a degenerative disease of the corneal epithelium due to interruption of the sensory innervation provided by the trigeminal nerve leading to full or partial corneal anesthesia.1 Decreased corneal sensation results in increased susceptibility to epithelial injury and mitigated healing responses in part due to reduced tearing, trophic factors, and blinking reflexes. In addition, increased mucous secretions lead to tears with increased viscosity further impairing corneal lubrication.2 Neurotrophic keratitis can quickly progress to corneal ulceration, melting, and perforation if not treated quickly and appropriately.Corneal hypoesthesia has many potential etiologies, including infection with herpes simplex or varicella zoster virus infections, fifth cranial nerve palsy due to surgery or other trauma, neoplasia (especially acoustic neuroma), aneurysm, or congenital conditions, including familial dysautonomia (Riley–Day syndrome), Goldenhar–Gorlin syndrome, Mobius syndrome, and familial corneal hypesthesia. To our knowledge, we report here the first case of neurotrophic keratitis in a patient with congenital disseminated lymphangiomatosis, a disorder that, in this patient, affected the boney structures surrounding Meckel’s (trigeminal) cave (see Figure 1) leading Dovepressopen access to scientific and medical researchOpen Access Full Text Articlesubmit your manuscript | www.dovepress.comDovepress C A S E  R E P O RTEye and Brain 2009:1to compression of the trigeminal nerve and subsequent corneal anesthesia.Case reportA 23-year-old male presented to his local ophthalmologist with a right corneal ulcer and visual acuity of light percep-tion (LP) in the right eye. The ulcer failed to heal with two weeks of topical lubrication, tobramycin, and cefazolin every 30 minutes as well as oflaxicin and moxifloxacin every four hours. The patient was then referred to us with a 2.8 mm × 3.5 mm right corneal ulcer with surrounding dense infiltrate, stromal haze, 2+ anterior chamber cells and flare but no hypopyon, and 4+ palpebral and bulbar conjunctival injection. The patient had no sensation in the right cornea as assessed with a cotton wisp, and visual acuity was 20/200 in the right eye. His medical history was significant for disseminated lymphangiomatosis, a disease characterized by diffuse or multifocal proliferation of lymphatic vessels within bone, soft tissue, and visceral organs,3 diagnosed at the age of 14 years. In this case, lymphatic proliferation affected the boney structures surrounding Meckel’s (trigeminal) cave, through which the trigeminal nerve passes (see Figure 1).The patient reported having a previous abrasion and infection of the right cornea 18 months prior to presentation that improved in one week after treatment with tobramycin and cefazolin ophthalmic drops. The history of disseminated lymphangiomatosis effacing Meckel’s (trigeminal) cave and corneal anesthesia led to a diagnosis of neurotrophic keratitis. Perhaps due to the multiple antibiotics the patient was taking upon referral, a culture for microbiology was negative for bacterial growth. The culture was also negative for fungus, herpes simplex virus (HSV), and Acanthamoeba. The patient was instructed to continue use of cefazolin every 30 minutes alternating with moxifloxacin every 30 minutes, tobramycin hourly, and he was also started on 100 mg oral doxycycline twice daily. The patient was urged to continue aggressive ocular lubrication during sleep and to use a moisture chamber at night. Finally, a bandage contact lens was placed.Due to difficulty in transportation to our clinic, the patient was followed locally. The ulcer worsened over the following two weeks, and fortified vancomycin was added to the treatment regimen. When we saw him again, he had a 9 mm epithelial defect (illustrated in Figure 2A) with vision of light perception. The infiltrate was stable, and vancomy-cin was discontinued. The patient was placed on autologous serum drops and drawstring temporary tarsorrhaphy was employed.4Ten days later, the epithelial defect measured 2.5 × 2.5 mm with a decreasing infiltrate (illustrated in Figure 2B). One month later, the epithelial defect had healed completely with resolution of the infiltrate (illustrated in Figure 2C). Visual acuity was 20/40.DiscussionA number of local ocular or systemic conditions that result in corneal anesthesia can cause neurotrophic keratitis. Damage to or compression of the trigeminal nerve from any source can eliminate corneal sensation and trigger the degenerative effects leading to destruction of the cornea. Here, we describe a case of neurotrophic keratitis A BFigure  A) Head CT without contrast demonstrating generalized bony changes associated with disseminated lymphangiomatosis.

Broad-spectrum antibiotics and aggressive lubrication lead to resolution of the infection, and drawstring temporary tarsorrhaphy eventually healed the corneal ulcer.Lymphangiomas are benign proliferations of well-differentiated lymphatic tissue characterized by increased numbers and complex arrangements of the lymph vessels.5 Lymphangiomatosis occurs when multiple lymphan-giomas are present, with disseminated lymphangiomatosis characterized by diffuse involvement of multiple tissues, especially bones and lungs. Lymphangiomatosis appears to be due to a developmental abnormality of the lymphatic system.3,6 Symptoms arise when progressive growth of the lymphangiomas compresses adjacent structures. In the 23-year-old male patient described here, lymphangiomatosis affected the bony structure of the skull likely leading to compression of the trigeminal nerve and subsequent anesthesia of the right cornea and face.Three clinical stages of neurotrophic keratitis have been defined.7,8 Stage I is characterized by Rose Bengal staining of the palpebral conjunctivae, decreased tear breakup time, increased viscosity of tear mucus, punctate epithelial staining with fluorescein, and scattered small facets of dried epithelium (Gaule spots). Stage II involves acute loss of epithelium, a surrounding rim of loose epithelium, stromal edema, aqueous cell and flare, and the edges of the defect becoming smooth and rolled. Finally, stromal lysis, which may result in corneal perforation, defines stage III. We assign the present case as stage III given the severe corneal ulcer with early stromal melting.To our knowledge, this is the first report of neurotrophic keratitis due to disseminated lymphangiomatosis. We hope that an awareness of this potentially disastrous blinding condition will lead to meticulous ocular examination, empathic patient education, and rigorous preventative care for these patients. This case also underscores the importance – in the setting of neurotrophic ulcer with secondary infectious keratitis – of appropriate therapies to aggressively address the A B CInfiltrate Edema ScarFluorescein Descemet’s folds DegenerationSuperficial vessels Stromal vessels Ghost vesselsFigure  Drawing of the patient’s cornea prior to A), ten days following B), and one month following C) drawstring temporary tarsorrhaphy.
