Efficacy of topical cyclosporin A 0.05% in conjunctival impression cytology specimens and clinical findings of severe vernal keratoconjunctivitis in children.

PurposeTo evaluate the efficacy of topical cyclosporin A 0.05% in managing the symptoms of severe vernal keratoconjunctivitis (VKC).MethodsFifty-four children with severe VKC were included in this study. All 54 patients were treated with topical cyclosporin A (CsA) 0.05% for 3 months. Ocular signs and symptoms were scored in all patients at entry and after 3 months. Conjunctival impression cytology specimens were examined on the day of enrollment and at the end of the treatment period.ResultsThe mean scores for severity of signs and symptoms significantly decreased after 3 months compared with those at entry (P < 0.001). The density of inflammatory cells in the conjunctival impression cytology specimens decreased significantly. No side effects of the treatment with CsA 0.05% eyedrops were observed.ConclusionsTopical CsA 0.05% eyedrops were found to be safe and effective in the treatment of patients with VKC. Consistent with these results, topical CsA may efficiently reduce conjunctival inflammation in severe VKC.

Is it necessary to accompany probing with endoscopy in cases of congenital nasolacrimal canal obstruction

OBJECTIVE To compare the results of probing with and without endoscopy in cases of congenital nasolacrimal duct obstruction who had previously not undergone probing. METHODS Fifty-one children with congenital nasolacrimal duct obstruction who underwent surgical intervention between June 2007 and April 2009 in our hospital were included in the study. Patients who had had previous probings were excluded from the study. Conventional probing was performed in 37 eyes of 25 patients, and probing with intranasal endoscopic visualization in 36 eyes of 26 patients. Diagnosis was based on history of epiphora since birth or shortly after, and fluorescein dye disappearance test. RESULTS Thirty-two of 37 eyes (86.48%) were cured by probing. Of the 5 cases with complaints, 1 had lacrimal sac fistula. Thirty-four of 36 eyes (94.44%) were cured by probing guided by endoscope observation. Thirty-two cases had stenosis at the lower end of the nasolacrimal duct which required probing. In two cases the probe passed submucosally to the floor of the nose. In two cases a false passage was made at the upper end of the inferior meatus. In these cases, the operation was continued by repeating the process until the distal end of the nasolacrimal canal was seen to have been passed. CONCLUSION Probing with endoscopy may be excessive in primary cases but in cases which have undergone unsuccessful probing, it is useful for visualization of anomalies in the lower nasolacrimal canal and to obtain the correct anatomic position for the probe.

Intravitreal bevacizumab combined with panretinal photocoagulation in the treatment of open angle neovascular glaucoma.

Purpose To evaluate the clinical efficacy of intravitreal bevacizumab (IVB) combined with panretinal photocoagulation in patients with open angle neovascular glaucoma (NVG). Methods Nine patients (9 eyes) with NVG participated in this study. Patients received IVB (1.25 mg) as the initial treatment for NVG and were followed up for at least 4 months. IVB was offered as the first treatment of choice to patients with NVG. Panretinal photocoagulation was performed as soon as feasible after the second week and completed in all patients the fourth week after IVB. The main outcome measures are resolution of INV, inhibition of peripheral anterior synechia (PAS), and controllability of intraocular pressure (IOP). Results The mean follow-up period was 5.6±1.4 months (range, 4–9 months). The mean IOP before treatment was 35.1±9.7 mmHg (range, 24–56) under medication before IVB treatment. After IVB and after combined treatment, the mean IOP was reduced to 22.8±8.1 mmHg (range, 9–33) and 13.0±4.0 mmHg (range, 7–20), respectively. The mean referral INV was 3.6±0.4 grade (range, 3–4) and reduced to 1.6±0.4 (range 1–2) grade after IVB and 0.6±0.8 (range 0–2) grade after combined therapy. By IVB, combined panretinal photocoagulation recurrence of INV was not observed. Conclusions In NVG, IVB treatment can reduce iris and angle neovascularization and inhibits further PAS formation temporarily. Panretinal photocoagulation inhibits neovascularization constantly. Therefore, management of open angle NVG is more feasible with bevacizumab combined with panretinal photocoagulation.

Distribution of central corneal thickness and intraocular pressure in a large population of Turkish school children.

Purpose: To determine the distribution of central corneal thickness (CCT) and intraocular pressure (IOP) in a population of Turkish school children and to evaluate the relationships between these values and both age and gender. Methods: A total of 30,320 eyes from 15,160 healthy school children aged 5–18 years were examined. CCT and IOP were measured using an ultrasonic pachymeter and a non-contact tonometer, respectively. Measurements were compared with age, gender, and parental consanguinity of subjects. Results: The mean age of the school children was 10.43 ± 2.54 years. For right eyes, mean CCT was 557.91 ± 34.26 µm and mean IOP was 14.15 ± 2.87 mmHg. Mean CCT was significantly thicker in males compared to females (P < 0.0001). Mean IOP was significantly higher in females compared to males (P < 0.0001). CCT in children aged 14 years and older was significantly thinner than that in the younger age groups (P < 0.0001). There was a significant difference among the age groups for IOP (P < 0.05). No significant differences were observed in CCT or IOP related to parental consanguinity (P = 0.538, P = 0.319, respectively). Conclusion: Mean CCT in Turkish school children is of comparable thickness to that in Western school children. CCT reached adult values around 14 years of age in our children. Furthermore, males had thicker CCT than females. IOP was lower in males than females, and increased with age.

Loxosceles reclusa bite to the eyelid.

Purpose The authors report a case of Loxosceles reclusa infestation on the eyelid. Methods The specimen collected by swabbing the lesions with gauze was tested by using a venom-specific enzyme-linked immunosorbent assay Loxosceles venom was detected in specimen. The patient was managed with conservative therapy that included saline compresses and ocular lubrication. Results The case presented with severe edema and necrosis on the left upper eyelid. On laboratory examination, a significant left shift of white blood cell count was detected. Although residual scar of the eyelid and punctate epitheliopathy on the inferior of cornea was detected, vision was not impaired. Conclusions Supportive therapy may be reasonable treatment for Loxosceles reclusa infestation on the eyelids. The presence of venom proteins detected with an enzyme-linked immunosorbent assay technique is beneficial for supporting the diagnosis of Loxosceles envenomatio.

Melkersson-Rosenthal syndrome with partial oculomotor nerve palsy.

Ann Saudi Med 28(2) March-April 2008 www.saudiannals.net 135 Melkersson-Rosenthal syndrome (MRS) is a rare granulomatous disease characterized by orofacial edema, facial nerve palsy, and furrowed tongue (lingua plicata).1,2 This is the classic triad which defines the syndrome, although it is accepted that the presence of two manifestations or one with a granulomatous cheilitis in the eyelid biopsy, is sufficient to make the diagnosis.3 Facial paralysis, most commonly unilateral, may also occur as well as a congenital fissuring of the tongue. It was first described in 1928 by Melkersson as a syndrome of recurrent facial palsy and edema, and Rosenthal later added the third feature of the syndrome, furrowing of the tongue, in 1931.4 The etiology of MRS is unknown, although both genetic and acquired factors have been implicated.2,5 Isolated eyelid edema, particularly bilateral involvement, is also rare, and as such it is usually misdiagnosed as orbital Melkersson-Rosenthal syndrome with partial oculomotor nerve palsy

The Effect of Extremely Low Frequency Magnetic Field on the Conjunctiva and Goblet Cells

Purpose: The aim of this study was to examine the effects of extremely low frequency magnetic field (ELF MF) on the conjunctiva and goblet cells density. Methods: Thirty adult female Spraque Dawley rats were assigned to one of two groups, each containing 15 rats. The experimental group received magnetic field 4 hr/day for 7 days. The second group received standard laboratory care and served as a control. The specimens were evaluated by light microscopy for goblet cell density, conjunctival edema, inflammation, and fibroblast proliferation. Results: In ELF MF exposure group rats, the number of goblet cells was less than the control group. We also observed a significant difference between ELF MF exposure group and control group in terms of goblet cell density (p = 0.010). The ELF MF exposure group manifested conjunctival edema and inflammation compared to the control group (p < 0.001 and p = 0.003). There was no statistical difference between the groups for fibroblast proliferation (p = 0.422). Conclusion: This study suggests that ELF MF exposure leads to morphological alterations of the conjunctiva and reductions in the number of goblet cells. We believe that ELF MF may cause dry eye symptoms.

Unilateral vernal keratoconjunctivitis: a case report.

Purpose A rare case of unilateral vernal keratoconjunctivitis is presented. Methods A 5-year-old boy had itching, foreign body sensation, redness, and ptosis in his left eye. Impression cytology specimens were taken from both upper eyelid tarsal conjunctiva. Results On slit-lamp biomicroscopy, unilateral cobblestone papillae and a shield ulcer were found in the left eye. On impression cytology examination, there was a significant increase in inflammation, presence of a honeycomb pattern, plasma cells, and mucus strands in the upper tarsal conjunctiva of the specimens. Conclusions Giant papillary conjunctivitis must be considered in differential diagnosis of unilateral vernal conjunctivitis. Impression cytology method may be combined with the clinical findings in vernal keratoconjunctivitis diagnosis.
