Abstract

Purpose: To determine the characteristics of an eye that developed acute hydrops while being treated for infectious keratitis. Observation: A 35-year-old man presented with pain and blurred vision in his left eye. He had undergone cataract surgery seven years earlier and was being treated for poorly controlled atopic dermatitis. The decimal best-corrected visual acuity (BCVA) of the left eye was 0.01. Slit-lamp microscopy showed conjunctival injection, corneal opacification, and a corneal ulcer. The patient was diagnosed with infectious keratitis and was treated with topical and systemic antibiotics. During the hospitalization, the patient was noted to rub his eyes frequently and vigorously. Five days after the first visit, the cornea protruded markedly, and the stroma surrounding the ulcerated area was edematous. These findings led to a diagnosis of acute hydrops.Penetrating keratoplasty was performed to prevent corneal perforation. Histopathological study of the excised cornea showed stromal edema, infiltration of leukocytes, and a tear in Descemet's membrane. Unfortunately, the patient developed endophthalmitis the day after the surgery. The anterior chamber was irrigated with antibiotics, and antibiotics were also injected into the vitreous. The endophthalmitis gradually subsided, and two years after the surgery, the patient's decimal BCVA had improved to 0.6. Conclusion and importance: Vigorous eye rubbing in cases of infectious keratitis can induce acute hydrops, and timely surgical intervention is recommended.

Abstract

Purpose: To report our findings in a case of pellucid marginal corneal degeneration (PMCD) in the left eye and keratoconus (KC) in the right eye, and to review earlier cases of PMCD and KC. Observations: A 45-year-old woman visited our hospital with a complaint of reduced vision in her right eye. She was predisposed to allergies since childhood and had a habit of rubbing her eyes. Based on the results of the corneal topographic study, we diagnosed her with KC in the right eye and PMCD in the left eye. We prescribed a rigid, gas permeable contact lens and treated her allergic conjunctivitis with ocular medications. Three years after her initial visit, she developed a corneal perforation in the left eye. The perforation was closed by conservative treatment consisting of therapeutic soft contact lens wear. One year after the cornea healed, the corneal astigmatism in the left eye was about one-half of what it was before the corneal perforation. Her corrected visual acuity improved to 1.0 with conventional spectacles. Conclusionand Importance: We found a difference in the progression of KC and PMCD even when they occurred in same individual. We suggest that the atopic predisposition, which is considered a risk factor for acute hydrops in KC, to be a risk factor for acute hydrops and corneal perforation in eyes with PMCD.

3. Development of Acute Hydrops in Eye with Infectious Keratitis: A case report

Abstract

Background: There have been relatively many reports of cases of acute hydrops followed by infectious keratitis, there has not been a report of cases of infectious keratitis complicated by acute hydrops. Case presentation: A 35-year-old man had undergone cataract surgery 7 years earlier and was being treated for atopic dermatitis by a neighborhood dermatologist. However, the dermatitis was poorly controlled. He came to our hospital with a complaint of pain and blurred vision in his left eye. The decimal best-correctly visual acuity (BCVA) of the left eye was 0.01. Slit-lamp microscopy showed conjunctival injection and a corneal opacity. The patient was diagnosed with infectious keratitis and treated with topical and systemic antibiotics. During his hospitalization, we noted that he frequently rubbed his eyes vigorously. Five days after the first visit, the cornea was noted to protrude markedly and the stroma surrounding an ulcerated area was edematous. These findings led to the diagnosis of acute hydrops and he underwent keratoplasty for the impending corneal perforation. Histopathological study of the excised cornea showed stromal edema, leucocyte infiltration, and a tear of Descemet membrane. Unfortunately, he developed endophthalmitis on the day after the surgery. We irrigated the anterior chamber with antibiotics and injected antibiotics into the vitreous. The endophthalmitis gradually subsided, and at two years after the surgery, his decimal BCVA had improved to 0.6. Conclusions: Eye rubbing in cases of infectious keratitis can induce acute hydrops and timely surgical intervention is recommended.

Three patients with inflamed conjunctival nevus were examined by slit-lamp biomicroscopy, and the findings before and after the treatments were compared.Results: All three patients had a slightly pigmented and edematous conjunctival tumor at the corneal limbal area. The tumors were hyperemic, and papillae and follicles were present on the superior conjunctiva in all patients. All of the patients had an allergic predisposition. The antiallergic treatment not only resolved the hyperemia and edema of the palpebral conjunctiva, but also reduced the tumor size. In one case, the topical antiallergic agent alone led to a reduction of the tumor size. A combination of topical antiallergic agent and topical immunosuppressant was effective in reducing the tumor size and degree of pigmentation in the other two patients.Conclusion: The hyperemia and pigmentation in eyes with inflamed conjunctival nevus can be resolved by topical antiallergic agent and topical immunosuppressant without resection of the tumor.Keywords: inflamed juvenile conjunctival nevus, epinastine, tacrolimus
