Endophthalmitis after tooth extraction in a patient with previous perforating eye injury
The aim of this stuty is to describe a case of endophthalmitis after tooth extraction in a patient with previous perforating eye injury . 50 years oldmale patient attempted to our clinic with complaints of sudden severe pain, reduced vision, light sensitivity and redness in the right eye. The patient stated that severe pain in his eye began approximately 12 hours following tooth extraction. The patient's ocular examination revealed a visual acuity of hand motion in the right eye. Anterior segment examination of the right eye showed intense conjunctival hyperemia, chemosis, a fine keraticprespitat and corneal edema. Dental procedures of the patients who had recently underwent ocular surgery or trauma should be done in a more controlled manner under anti -infective therapy or should be postponed in elective procedures
Corneal melting after collagen cross-linking for keratoconus: a case report
<p>Abstract</p> <p>Introduction</p> <p>Corneal collagen cross-linking is a rather new technique that uses riboflavin and ultraviolet A light for collagen fiber stabilization in keratoconus corneas. Other than reversible side effects, the preliminary results of corneal collagen cross-linking studies suggest that it is a rather safe technique. In this report, we demonstrate a case of corneal melting after corneal collagen cross-linking for keratoconus corneas associated with an acute inflammatory response.</p> <p>Case presentation</p> <p>A 23-year-old Caucasian man with keratoconus cornea stage 1 to 2 underwent uneventful corneal collagen cross-linking treatment according to the Dresden protocol. The next day the patient had intense photophobia, watering and redness of the eye, and his visual acuity was limited to counting fingers. Slit lamp biomicroscopy revealed severe corneal haze accompanied by non-specific endothelial precipitates following an acute inflammatory response. Mild inflammation could be detected in the anterior chamber. Moreover, the re-epithelialization process could barely be detected. His corneal state gradually deteriorated, resulting in descemetocele and finally perforation.</p> <p>Conclusion</p> <p>In this report, we present a case of a patient with corneal melting after standard corneal collagen cross-linking treatment for keratoconus corneas following an acute inflammatory response. Despite modifying postoperative treatment, elaboration of all apparent associated causes by the treating physicians and undergoing extensive laboratory testing, the patient developed descemetocele, which led to perforation. Our report suggests that further research is necessary regarding the safety of corneal collagen cross-linking in keratoconus corneas.</p
FULL-THICKNESS MACULAR HOLE WITH MACULAR INTRACHOROIDAL CAVITATION IN A PATIENT WITH PATHOLOGIC MYOPIA
PubMed: 29443802PURPOSE: To describe a full-thickness macular hole (MH) opening to macular intrachoroidal cavitation in a patient with pathologic myopia. METHODS: Full ophthalmologic examination, fundus camera (Topcon TRC; Topcon Co, Tokyo, Japan), optical coherence tomography (RetinaScan Advanced RS-3000; NIDEK, Gamagori, Japan) imaging, and cataract surgery. RESULTS: A 61-year-old woman admitted with decreased vision in the left eye. Visual acuity was counting fingers from 30 cm. Anterior segment examination showed advanced cataract. Fundus examination revealed pathologic myopia. There was full-thickness MH opening to macular intrachoroidal cavitation in contact with the anterior surface of the sclera subfoveally. Except for the communicating part of MH and macular intrachoroidal cavitation, outer retina, ellipsoid zone, and retinal pigment epithelium were intact. Choroid was intact except for a small part at subfoveal area. The patient received an uncomplicated cataract surgery. Visual acuity improved to 5/10. Because she was satisfied, MH surgery was postponed to a later date. CONCLUSION: Full-thickness MH may occur within the area of macular intrachoroidal cavitation in pathologic myopia
Peripapillary and macular retinoschisis in a patient with pseudoexfoliation glaucoma
A 55-year-old man was admitted with a 2-year history of pseudoexfoliation glaucoma. The best-corrected visual acuities were 10/10 in both eyes. Pseudoexfoliation material was noted on the iris and the lens capsule. Fundus examination evidenced cup-to-disc ratio of 0.7 OD and 0.9 OS with peripapillary atrophy. Gonioscopy revealed open angles. Optical coherence tomography demonstrated peripapillary retinoschisis extending to the nasal macula in the left eye and optic nerve head was almost fully excavated. Coexisting retinoschisis in a patient with glaucoma may interfere with the reliability of retinal nerve fibre layer and ganglion cell complex analysis and may change the treatment plan and follow-up intervals.

Limbal stem cell defficiency associated with primary adrenocortical insufficiency
Objective: To report a female patient with bilateral limbal stem cell deficiency (LSCD) due to primary adrenocortical insufficiency (PAI).Methods: Case report Results: A 40-year-old female patient had blurry vision, foreign body sensation, tearing, and photophobia for several years. On examination, corneal epithelial haze, surface irregularity, and superficial neovascularization were observed. There was a dull and irregular reflex from the conjunctivalized corneal surface. Medical history revealed that she had a diagnosis of PAI for 11 years and received hormone replacement (fludrocortisone acetate) therapy. With the clinical presentation and examination, the diagnosis was compatible with LSCD. Frequent ocular lubricant and topical steroid drops were initially started and topical cyclosporine treatment was planned for the long term. After 3 weeks, there was no corneal superficial neovascularization and epithelial haze, peripheral stromal haze was still observed. Conclusion: LSCD may rarely be associated with PAI. In patients with LSCD, systemic evaluation should be made to rule out PAI
Anesthetic effectiveness of topical levobupivacaine 0.75% versus topical proparacaine 0.5% for intravitreal injections
Background and Purpose: Today no method of topical anesthesia for intravitreal injection administration has been proven to make the patient comfortable yet. We compared the efficacy of topical levobupivacaine 0.75% and proparacaine 0.5% in patients undergoing intravitreal injections. Materials and Methods: A prospective, randomized study comparing two agents for topical anesthesia in intravitreal injections. Ninety-six consecutive patients were enrolled into two groups to receive either topical levobupivacaine 0.75% (n=48) or proparacaine 0.5% (n=48). Patients were asked to score their pain using a visual analog scale (VAS) immediately following the injection. The average of these scores was used as the primary outcome. The surgeon performing the procedure scored his perception of the patients? pain using the Wong-Baker FACES scale. Results: Mean VAS pain scores for two groups were found to be 44.77 ± 16.42 and 34.18 ± 14.83, respectively. Mean VAS pain score in the proparacaine group was significantly lower than that in the levobupivacaine group (P= 0.003). Mean Wong-Baker FACES scores for the two groups were 1.08 ± 0.49 and 1.10 ± 0.30, respectively. There was no statistically significant difference between levobupivacaine and proparacaine groups (P=0.824). Conclusions: Topical proparacaine 0.5% was more effective in preventing pain during intravitreal injections
Comparison of the antimicrobial effect of heavy silicone oil and conventional silicone oil against endophthalmitis-causing agents
PubMed: 24817741Purpose: To conduct an in vitro experimental study comparing the effectiveness of conventional silicone oil and heavy silicone oil against endophthalmitis-causing agents. Materials and Methods: The antimicrobial activity of conventional silicone oil (RS OIL 5000) and heavy silicone oil (heavySil 1500) was tested. The antimicrobial effects of both silicone oils were determined by the growing capability of the microorganism. Results: The number of Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans decreased to zero levels at the second day of inoculation in heavy silicone oil. In conventional silicone oil, the microorganisms survived longer than in heavy silicone oil. Conclusion: Heavy silicone oil seems to be more effective than conventional silicone oil against endophthalmitis-causing agents. © 2005 - Indian Journal of Ophthalmology
Antimicrobial effectiveness of silicone oil, heavy silicone oil and perfluorodecaline against Bacillus cereus
PubMed: 24375026The purpose of this work is to study the effectiveness of silicone oil, heavy silicone oil and perfluorodecaline against Bacillus cereus. For this we tested the antimicrobial activities of three intraocularly used liquids-silicone oil (Siluron 1000), heavy silicone oil (Densiron-68) and perfluorodecaline (F-Decalin)-against B. cereus (NCTC 9946). The antimicrobial effects of silicone oil, heavy silicone oil and perfluorodecaline were determined by the growing capability of the microorganism. We found that the number of B. cereus decreased in all three concentrations of silicone oil. The bacteria grew for approximately 2 weeks in heavy silicone oil and declined after 17 days. Perfluorodecaline significantly reduced B. cereus colonies and was the most effective of the liquids. In conclusion, silicone oil and perfluorodecaline seem to be effective against B. cereus. © 2013 Springer Science+Business Media
Bilateral consecutive optic neuropathy in a patient with thrombophilia
A 39-year-old man was admitted with a sudden visual loss in the left eye. Visual acuities were 10/10 on the right and 1/10 on the left. Fundus examination did not show any abnormalities. Visual acuity improved to 10/10 and visual field defect regressed in the following 2 weeks. Three years later, the patient returned with acute visual loss in the right eye. Visual acuities were 2/10 on the right and 10/10 on the left. Right optic disc had blurred margins with mild oedema. The tests revealed methylenetetrahydrofolate reductase A1298C mutation with positive lupus anticoagulant and hyperhomocysteinaemia. Enoxaparin was initialised with vitamin B12 supplementation. Complete visual recovery occurred in the following 3 weeks in both eyes. Thrombophilic screening seems to be important in the treatment and prevention of an attack in the second eye of patients with non-arteritic anterior ischaemic optic neuropathy.
