1/49. Streptococcal keratitis after myopic laser in situ keratomileusis.A 24-year-old healthy male underwent uncomplicated laser in situ keratomileusis (LASIK) in left eye. One day after the surgery, he complained of ocular pain and multiple corneal stromal infiltrates had developed in left eye. Immediately, the corneal interface and stromal bed were cleared, and maximal antibiotic treatments with fortified tobramycin (1.2%) and cefazolin (5%) were given topically. The causative organism was identified as 'Streptococcus viridans' both on smear and culture. Two days after antibiotic therapy was initiated, the ocular inflammation and corneal infiltrates had regressed and ocular pain was relieved. One month later, the patient's best corrected visual acuity had returned to 20/20 with -0.75 -1.00 x 10 degrees, however minimal stromal scarring still remained. This case demonstrates that microbial keratitis after LASIK, if treated promptly, does not lead to a permanent reduction in visual acuity.- - - - - - - - - - ranking = 1keywords = keratitis (Clic here for more details about this article) |
2/49. Bacterial keratitis following laser in situ keratomileusis for hyperopia.A 42-year-old Bahraini man had uneventful laser in situ keratomileusis for hyperopia (OD: 3.00 0.75 x 155 degrees; OS: 2.00 0.50 x 155 degrees). Three weeks later, he presented with localized keratitis in his right eye, with localized keratitis at the flap margin with stromal edema. Uncorrected visual acuity was 20/80 OD with no improvement with pinhole, and was 20/20 OS. Corneal smear culture showed a positive growth of staphylococcus aureus. The patient was immediately treated with subconjunctival gentamicin and intensive topical ofloxacin 0.3% with systemic cephalosporin. The patient recovered from keratitis within 2 weeks and his uncorrected visual acuity OD improved to 20/20. keratitis following LASIK should be treated promptly so that it does not lead to permanent reduction in visual acuity.- - - - - - - - - - ranking = 1.4keywords = keratitis (Clic here for more details about this article) |
3/49. Infectious keratitis after photorefractive keratectomy in a comanaged setting.A 48-year-old man had simultaneous bilateral photorefractive keratectomy (PRK). The surgeon who performed the PRK did not see the patient in follow-up, and there was confusion regarding the comanaging doctor. Therefore, the patient was not examined immediately postoperatively. Several days later, he was hospitalized for an unrelated, painful orthopedic problem and heavily sedated. Seven days after the PRK, an ophthalmologist was consulted for ocular irritation and discharge. Examination showed bilateral, purulent conjunctivitis and severe infectious keratitis in the left eye. The patient was treated with periocular and topical antibiotics. Corneal cultures yielded staphylococcus aureus. The keratitis resolved slowly, leaving the patient with hand motion visual acuity. A corneal transplant and cataract extraction was performed 15 months later, resulting in a best corrected visual acuity of 20/400 because of glaucomatous optic nerve damage. Severe infectious keratitis may occur after PRK. Poor communication between the surgeon, comanaging doctor, and patient may result in treatment delay.- - - - - - - - - - ranking = 1.4keywords = keratitis (Clic here for more details about this article) |
4/49. Pneumococcal keratitis after laser in situ keratomileusis.A 20-year-old man developed keratitis in his right eye 2 days after laser in situ keratomileusis (LASIK). The patient had rubbed the eye with unclean fingers the night before the onset of symptoms. Examination showed an inferior corneal ulcer with dense infiltration at the junction of the lamellar flap and the surrounding cornea associated with a hypopyon. streptococcus pneumoniae was isolated on culture. The ulcer resolved with combination therapy of cephazolin 5% and tobramycin 1.3% eyedrops. patients having LASIK should be instructed that inadequate patient hygiene may predispose to bacterial keratitis.- - - - - - - - - - ranking = 1.3932086795423keywords = keratitis, corneal ulcer, ulcer (Clic here for more details about this article) |
5/49. Mycobacterium keratitis after laser in situ keratomileusis.PURPOSE: The authors report two cases of Mycobacterium keratitis following LASIK. methods: The case reports are based on a retrospective review of clinical history and associated findings. RESULTS: Two patients developed infectious keratitis after undergoing laser in situ keratomileusis (LASIK). In case #1, the infection developed after manipulation of the lamellar flap to remove epithelium from the stromal bed. In case #2, prior radial keratotomy may have been a contributing factor to development of the infection. Corneal infiltrates appeared as focal, white, stromal deposits. Cultures isolated mycobacterium fortuitum from case #1 and mycobacterium chelonae from case #2. Topical fortified amikacin, clarithromycin, tobramycin, and ciprofloxacin eventually controlled the infection. Topical prednisolone acetate and bandage contact lenses were necessary to control inflammation and pain. Infiltrates were slow to resolve until focal necrosis eroded through the flaps leading to rapid clearing of the infiltrates; however, scarring of the cornea developed at the site of necrosis. Visual recovery was good in the first case but limited in the second. CONCLUSIONS: Mycobacterium keratitis complicating LASIK may be difficult to eradicate until the sequestered stromal infiltrate drains. Rapid recognition of the causative organism and aggressive medical and surgical management of the infection may improve the outcome.- - - - - - - - - - ranking = 1.4keywords = keratitis (Clic here for more details about this article) |
6/49. Fungal keratitis after laser in situ keratomileusis.A 22-year-old woman presented with pain, redness, watering, and decrease in vision in her left eye 15 days after laser in situ keratomileusis for myopia. Slitlamp examination showed a central full-thickness infiltrate with hyphate edges. Microscopic examination of corneal scrapings from the edge and underneath the flap showed fungal filaments, and the growth on culture media was identified as scedosporium apiospermum.- - - - - - - - - - ranking = 0.8keywords = keratitis (Clic here for more details about this article) |
7/49. Medical management of beauveria bassiana keratitis.PURPOSE: To describe a case of beauveria bassiana keratitis and to discuss the management of this rare condition. methods: An 82-year-old woman underwent surgical repair of a graft wound dehiscence. Seven months later, shortly after the removal of sutures, the patient developed a fungal keratitis. B. bassiana was identified as the infecting organism. The patient was treated with topical natamycin and oral fluconazole. RESULTS: Following antifungal therapy, the corneal ulcer was eradicated, but the patient underwent repeat penetrating keratoplasty for decreased vision due to corneal edema. The graft remains clear and visual acuity is substantially improved. CONCLUSION: The medical management of B. bassiana keratitis has previously been unsuccessful. The use of topical natamycin combined with oral fluconazole in the management of this case is discussed.- - - - - - - - - - ranking = 1.5922386211643keywords = keratitis, corneal ulcer, ulcer (Clic here for more details about this article) |
8/49. pyoderma gangrenosum occurring in a lower limb fasciocutaneous flap--a lesson to learn.pyoderma gangrenosum is a destructive cutaneous disease characterised by progressive painful ulceration. The occurrence of pyoderma gangrenosum at a surgical site is rare (especially if there is no predisposing illness), but is well recognised. We present a case of a 63-year-old man who developed erythematous ulcerative lesions due to pyoderma gangrenosum in and around a lower limb fasciocutaneous flap used to cover an exposed total knee prosthesis. The lesions were initially confused with postoperative wound infection. No predisposing disorder, other than the rarely reported association with osteoarthritis, was found. The diagnosis is important because its rapid detection not only avoids unnecessary treatment but also allows for prompt intervention with oral steroids. This case is presented to alert surgeons to the presence of pyoderma gangrenosum and its diagnostic confusion with postoperative wound infection.- - - - - - - - - - ranking = 0.0019401167558814keywords = ulcer (Clic here for more details about this article) |
9/49. Delayed keratitis after laser in situ keratomileusis.We report 2 cases of delayed keratitis that occurred after uneventful laser in situ keratomileusis (LASIK). The first patient presented with a peripheral corneal infiltrate 3 months after a LASIK enhancement procedure. The infiltrate progressed despite treatment with topical combination tobramycin-dexamethasone. The flap was then lifted and the interface was irrigated with fortified antibiotics. The keratitis promptly resolved, and the patient recovered a best corrected visual acuity (BCVA) of 20/20. The second patient presented with decreased vision, inflammation, and a sublamellar infiltrate 1 month after primary LASIK. The flap was promptly lifted and irrigated with antibiotics. Cultures were positive for staphylococcus epidermidis. One week later, the infiltrate had resolved and BCVA had returned to 20/20. Delayed bacterial keratitis has been described as a rare occurrence after incisional refractive surgery. To the best of our knowledge, it has not yet been reported after LASIK. It is important to consider infectious keratitis in the differential diagnosis of a patient who presents with corneal inflammation, even months after having LASIK.- - - - - - - - - - ranking = 1.6keywords = keratitis (Clic here for more details about this article) |
10/49. Keratomycosis after cataract surgery.PURPOSE: To evaluate cases and results of keratomycosis that developed after cataract surgery. SETTING: Hospital de Guipuzcoa, San Sebastian, spain. methods: This retrospective study comprised 8 patients who developed keratomycosis soon after cataract surgery. RESULTS: Culture analysis revealed 7 cases of aspergillus fumigatus and 1 of aspergillus flavus. After medical treatment with antifungal agents, 6 cases resolved and 2 required evisceration. CONCLUSIONS: The presence of fungi in corneal ulcers that develop after cataract surgery should be considered. Initiation of early treatment determines the prognosis. Among the therapeutic options, collagen shields soaked in amphotericin b may be effective.- - - - - - - - - - ranking = 0.19223862116434keywords = corneal ulcer, ulcer (Clic here for more details about this article) |
